  5. 5. GSM Association Official Document DG.09 1 INTRODUCTION 1.1 Overview This document is applicable to GSM, GPRS, WCDMA, WLAN and multi mode terminals. It defines mobile equipment (MS/UE) power consumption test methods for specific technologies, applications and services. 1.2 Scope Comparing the standby and talk times of handsets is a complicated process because of the number of parameters that affect these results. For GSM an industry standard parameter set was agreed. This is described in the TW09 specification [1]. However, handset technology has moved on since the specification was agreed. Expansion of this specification is needed to cover additional radio access such as GPRS, WCDMA and WLAN as well as to cover usage of dedicated software, services or interface connection. This document is applicable to GSM, GPRS, WCDMA, WLAN and multi mode terminals. It defines mobile equipment (MS/UE) power consumption test methods for specific technologies, applications and services. The document describes a selection of basic measurements that are representative of the main uses of mobile equipment (MS/UE) with a view that the resulting figures can provide a measure of battery performance whilst being exercised by a specific technology within a specified parameter set. Whilst the figures are not intended to provide a definitive power consumption figure for a MS/UE, they may be used to extrapolate indicative power consumption data for complicated usage scenarios. In this document, main categories of features have been defined to rationalise the amount of testing required, whilst maintaining an overview of the battery performance. The categories are illustrated in the diagram below. Within these categories, all possible scenarios have been listed. A lot of combinations have been identified as representative of the user experience. The most representative scenario in each category has been selected, and defined in detail. The performance figures produced by the tests are intended to give benchmarks for the operators to use when comparing terminals. It is not anticipated that the figures will be made available to end-users. Main categories covered in this document: Page 5 of 64

Then it describes the selected scenarios that were limited on purpose to make the testing feasible. Page 6 of 64
  7. 7. GSM Association Official Document DG.09 2.1 Possible Scenarios The two user parameters measured under [1] are standby and talk time. Considering handsets in the market place at present, and the development trends, it appears that these two scenarios are the only ones that are common to all handsets. We will therefore attempt to expand these to cover the new network technologies. 2.1.1 Standby Time We have the following possible operation modes to be considered for standby: Operational Mode GSM Dual mode GSM/WCDMA GSM/ GPRS Dual mode GPRS/WCDMA WCDMA Dual mode WCDMA/(GSM/GPRS) WLAN Dual mode Cellular/WLAN Table 2.1: Standby Time possible scenarios 2.1.2 Talk Time For talk time, we need to redefine our terms a little – “talk time” is not applicable to packet. For circuit switched connections we propose to keep “talk time”, but for packet switched “connection time” is a more appropriate term. As will be seen later, it may be commercially preferable to express packet switched results in terms of data transferred rather than time. 2.1.2.1 Circuit Switched The following possible operation modes have to be considered for circuit switched talk time: Operational Mode GSM Dual mode GSM/WCDMA WCDMA Dual mode WCDMA/GSM WLAN Dual mode Cellular / WLAN Table 2.2: Talk Time possible scenarios 2.1.3 Connection Time 2.1.3.1 Packet Switched The following possible operation modes have to be considered for packet switched connection time: Operational Mode GSM/GPRS Dual mode GPRS/WCDMA WCDMA Dual mode WCDMA/GPRS WLAN Dual mode Cellular/WLAN Page 7 of 64
  8. 8. GSM Association Official Document DG.09 Table 2.3: PS Connection Time possible scenarios 2.1.3.2 Circuit and Packet Switched Simultaneously The following possible operation modes have to be considered for simultaneous circuit and packet switched connection time: Operational Mode GSM Dual mode GSM/WCDMA GSM/ GPRS Dual mode GPRS/WCDMA WCDMA Dual mode WCDMA/(GSM/GPRS) WLAN Dual mode Cellular/WLAN Table 2.4: CS+PS Connection Time possible scenarios In existing networks simultaneous CSD and PSD are only possible in WCDMA – however dual mode monitoring is still performed to allow fallback to a less sophisticated service on GSM/GPRS. It should be noted that Dual Transfer Mode (DTM) would allow simultaneous packet and circuit switched operation in GSM/GPRS. However this technology is not yet deployed. Once it is, this section may need to be revisited. 2.1.4 Browsing The following possible operation modes could be considered for circuit, packet or simultaneous switched connection time: Operation Operational Mode Browsing WAP 1.x Browsing WAP 2.x Browsing iMode Browsing HTML Table 2.5: Browsing possible scenarios 2.1.5 Interface connection The following possible interface connections could be considered for either circuit or packet switched connection time: Page 8 of 64

  13. 13. GSM Association Official Document DG.09 From the possible combinations of applications and cellular technology, several representative scenarios have been selected. If the terminal is WCDMA capable, the following scenarios apply: Page 13 of 64

  15. 15. GSM Association Official Document DG.09 • Dual mode scenarios are for further study 2.3 Parameter Selection For our definitions to be of use, we must select parameters that meet the following criteria: • Representative of real network deployment • Capable of being produced with a minimum amount of test equipment • Use only features present on existing test equipment • Define available options unambiguously It may be that some of the above are contradictory. This will be considered in the following sections if applicable. Where options allow, the parameters in this document are meant to be more representative of urban usage, as this is the most common user experience. For example this can affect such parameters as number of neighbour cells, transmit power, etc. 2.4 Common Parameters There are certain parameters that are common to all modes of operation. We intend to adopt these values directly from [1]. The items in question are as follows: Item Parameter Ambient Temperature 18-25 Celsius PLMN Home Backlight Default setting SIM Supporting clock stop Keypad No activity Cell broadcast Not used Table 2.11a: Common parameters to all modes of operations We also propose additional common parameters: Item Parameter Additional services Disabled System Information 13 Present Table 2.11b: Additional common parameters to all modes of operations “Additional Services” is intended to cover new additions to the standards such as location services. These new features are generally optional. They are also difficult to arrange in a test configuration. In view of this, we believe that they should be excluded from the standard scenarios. Page 15 of 64
  16. 16. GSM Association Official Document DG.09 “System information 13” is an optional message which allows for more efficient decoding of BCCH. This is an important message for GPRS; although optional, it is almost universally used. Therefore it has been added to the scenario. The display contrast / brightness shall be set to the default values as delivered from the factory. Test environment lighting should be typical office conditions with no direct sun shining on the device under Test. The audio volume shall be set to the middle of the available range. If graduations are displayed this is the middle graduation mark. Furthermore, if the tester perceives that the volume is too low; the reference volume is increased subjectively up to a realistic level. 3 STANDBY TIME TEST 3.1 GSM A generally accepted model is provided by [1]. Key parameters are as follows and they apply to all scenarios run in standby mode unless otherwise specified. The common parameters mentioned earlier also apply. The GSM configuration of the tests is described below. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results. Parameter Value Comment All values are chosen to be mid band. ARFCN : All bands supported by 62 for 900 MHz the handset must be 698 for 1800 MHz measured. BCCH 660 for 1900 MHz Results must indicate 276 for 450 MHz which band(s) have 323 for 480 MHz been measured, and 189 for 850 MHz individual result for each band RX level -82 dBm Cell Reselection No Paging interval 5 multi frames No of neighbour cells 16 frequencies as defined in appendix declared in the BA_LIST Periodic location T3212 = 0 No updates Cell broadcast No Table 3.1: GSM parameters for Standby Time Page 16 of 64
  17. 17. GSM Association Official Document DG.09 Note that, although the mobile is required to monitor these neighbour cells, the test equipment does not in fact provide signals on these frequencies. It is explicitly stated in [1] that no signals should be present on the neighbour frequencies. If signals are present then the handset will attempt to synchronise to the best 6, and this is not part of the test. 3.2 GSM/GPRS For GPRS most of the key parameters can be kept from GSM (see previous section) but the paging type and interval needs to be addressed. Three possibilities for paging type are available: 1. Network mode of operation I. All paging messages (GSM or GPRS) are sent on the PPCH - or CCCH-PCH if no PPCH is present. In PS connected mode CS paging arrives on the PDTCH. 2. Network mode of operation II. All paging messages are sent on the CCCH-PCH whether PS connected or not. This means the mobile must monitor paging channel even when in a packet call. 3. Network mode of operation III. CS and PS paging operations are completely uncoordinated and may or may not be on separate paging channels. Most deployed GPRS networks operate in mode I or mode II, so mode I as been adopted as the standard. For simplicity the paging has been selected to arrive on the CCCH-PCH, this is also the paging channel used under [1]. Finally the paging interval needs to be considered. As the decisions on paging mode and channel lead to use the same paging system as in GSM, the same paging interval was selected: 5 multi frames. Parameter Value Comment Network Mode of I Operation Paging channel CCCH-PCH Unless operator Paging interval 5 multi frames requests a different value All other parameters As for GSM standby. Table 3.2: GSM/GPRS parameters for Standby Time Note: the selected parameters for GSM/GPRS standby are effectively the same as those used in [1] for GSM. Thus the same results should be obtained when measuring/modelling GSM under [1] and GSM/GPRS under the details above. Page 17 of 64
  18. 18. GSM Association Official Document DG.09 3.3 WCDMA The WCDMA bearer configuration of the tests is described below. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results. Parameters apply to all scenario run in standby mode unless otherwise specified. Some items can be directly adopted from GSM: Item Parameter Cell Reselection No Cell Broadcast No Additional services Disabled Page 18 of 64
  19. 19. GSM Association Official Document DG.09 Parameter Recommended Value Comment Band I: Mid Range Band II: Mid Range All bands supported by Band III: Mid Range the handset must be Band IV: Mid Range measured. Serving Cell UARFCN Band V: Mid Range Results must indicate (downlink) Band VI: Mid Range which band(s) have been Band VII: Mid Range measured, and individual Band VIII: Mid Range result for each band Band IX: Mid Range Number of neighbours declared in the 16 See Note BA_LIST Neighbour cells on No different frequency Used value shall be Serving Cell Any reported with the test Scrambling Code results See Note. Used values Neighbour cell Any shall be reported with the scrambling codes test results This value must be used Paging Interval 1.28 seconds (DRX 7) unless operator requests 2.56 s (DRX 8). Periodic location No T3212 = 0 updates This level is typically CPICH_RSCP (Ec) -97 dBm seen on network serving cells This level is measured as Serving cell code -5 dB an offset from channel power (DPCH_Ec/Ior) power Ec/No > 12 dB This parameter shall not SIntrasearch Not applicable be sent. Refer to [8] section 5.2.6.1.1 This parameter shall not SsearchRAT Not applicable be sent. Refer to [8] section 5.2.6.1.1 Table 3.3: WCDMA parameters for Standby Time Note: although the mobile is required to monitor these neighbour cells, the test equipment does not in fact provide signals. It is explicitly stated in [1] that no signals should be present on the neighbour frequencies. If signals are present then the handset will attempt to synchronise and this is not part of the test.

  20. 20. GSM Association Official Document DG.09 3.4 GSM/WCDMA Dual Mode In this scenario the terminal is camped on GSM according to section 3.1 with the addition that the neighbour cell list includes also WCDMA cells according to section 3.3. Table 3.1 applies with the addition to the BA_LIST of 16 WCDMA neighbour cells on the same UARFCN. Note: If the test equipment does not support 16+16 neighbour cell configuration then chose the best fit possible and note in B.1. 3.5 (GSM/GPRS)/WCDMA Dual Mode In this scenario the terminal is camped on GSM/GPRS according to section 3.2 with the addition that the neighbour cell list includes also WCDMA cells according to section 3.3. Table 3.1 applies with the addition to the BA_LIST of 16 WCDMA neighbour cells on the same UARFCN. Note: If the test equipment does not support 16+16 neighbour cell configuration then chose the best fit possible and note in B.1. 3.6 This is for further study. WCDMA (GSM/GPRS) Dual Mode In this scenario the terminal is camped on WCDMA according to section 3.3 with the addition that the neighbour cell list includes also GSM/GPRS cells according to section 3.2. Table 3.3 applies with the addition to the BA_LIST of 16 GSM neighbour cells with frequencies as defined in Appendix A.2. Note: If the test equipment does not support 16+16 neighbour cell configuration then chose the best fit possible and note in B.1. 3.7 WLAN in conjunction with GSM or WCDMA This section is applicable for device with Wi-Fi capabilities. WLAN parameters of the test Access Point (AP) are described below: Parameter Mandatory Value Comment WLAN standards Wi-Fi 802.11b/g Wi-Fi frequency 7 Authentication / WPA-PSK Ciphering DTIM period 3 All WLAN tests shall be 1) Both turned on WMM/UAPSD power run twice with AND save WMM/UAPSD turned 2) Both turned off on and turned off. Wi-Fi RSSI -70 dBm Beacon interval 100ms Table 3.4: Access Point WLAN parameters WLAN parameters of the device under test are described below: The device shall be put in the mode that the user will encounter in the production model. Those values need to be recorded into the Performa table: Page 20 of 64
  21. 21. GSM Association Official Document DG.09 Recommended Parameter Comment Values Used value shall be reported with the test WLAN standards Wi-Fi 802.11b/g results Used value shall be reported with the test Long Retry Limit 4 results Used value shall be reported with the test Short Retry Limit 7 results Used value shall be reported with the test RTS threshold 2346 results Used value shall be reported with the test TX Power Level 100mW results Wi-Fi Network Scan Used value shall be reported with the test Every 5 minutes Period results Table 3.5: Device WLAN parameters 3.7.1 GSM Standby Time, Wi-Fi enabled, no AP This scenario is similar to GSM Standby Time scenario (ref. chapter 4.1) however for this test the Wi-Fi radio must be enabled within the device and the device must periodically searching for Wi-Fi access points. For this test no Wi-Fi access points shall be in range, so the handset will be forced to search for an access point without ever finding one. The GSM parameters for this test are the same as for the GSM test described in section 4.1 The Wi-Fi parameters for this test are stated earlier in this section of the document. The other common parameters mentioned earlier in this document also apply. All parameters and the selected values used for the test shall be reported with the tests results. 3.7.2 GSM Standby Time, Wi-Fi enabled, device connected to AP The set up for this test is similar to the GSM standby time test defined in section 4.1 of this document the only difference being that a Wi-Fi access point is present as shown in the diagram below. For this test the device must be connected and registered to both the GSM test set and the Wi-Fi access point at the same time. The device must therefore monitor the paging / beacon frames from both technologies at the same time. The Wi-Fi is directly connected to Public Internet (not GAN, nor VPN). Figure 3.1: Test set-up for GSM Standby / Wi-Fi enabled Page 21 of 64
  22. 22. GSM Association Official Document DG.09 The GSM parameters for this test are the same as for the GSM test described in section 3.1 The Wi-Fi parameters for this test are stated earlier in this section of the document. No active data transmission shall be stimulated by the tester across the Wi-Fi radio bearer. The other common parameters mentioned earlier in this document also apply. The parameters and the selected values used for the test shall be reported with the tests results. 3.7.3 GAN Standby Time over WLAN, GSM coverage available This section is designed to test the effect of GAN over Wi-Fi radio capabilities on the standard operation of a handset. Clearly the tests are only applicable to a handset that supports GAN over Wi-Fi. Device is in GAN preferred mode. The GAN network parameters of the tests are described below: Parameter Mandatory Value Comment Keep alive timer 100 seconds ESP rekeying (IPSec) 1 hour IKE rekeying (IPSec) 8 hours Table 3.6: GAN network parameters It is also assumed that a 900 MHz GSM cell covers the GAN cell: parameters can be kept from previous section 3.1. 3.7.4 WCDMA Standby, Wi-Fi enabled, no AP This scenario is similar to WCDMA Standby Time scenario (ref. chapter 3.3) however for this test the Wi-Fi radio must be enabled within the device and the device must periodically search for Wi-Fi access points. For this test no Wi-Fi access points shall be in range, so the handset will be forced to search for an access point without ever finding one. 3.7.5 WCDMA Standby, Wi-Fi enabled, device connected to AP The set up for this test is similar to the WCDMA standby time test defined in section 3.3 of this document the only difference being that a Wi-Fi access point is present as shown in the diagram below. For this test the device must be connected and registered to both the WCDMA test set and the Wi-Fi access point at the same time. The device must therefore monitor the paging/beacon frames from both technologies at the same time. The Wi-Fi is directly connected to the Public Internet (not GAN, nor VPN). Page 22 of 64

GSM Association Official Document DG.09 Figure 3.2: Test set-up for WCDMA standby, Wi-Fi enabled The WCDMA parameters for this test are the same as for the WCDMA standby test described in section 3.3 The Wi-Fi parameters for this test are stated earlier in this section of the document. No active data transmission shall be stimulated by the tester across the Wi-Fi radio bearer. The other common parameters mentioned earlier in this document also apply. The parameters and the selected values used for the test shall be reported with the tests results. 4 TALK TIME TEST 4.1 GSM All the common parameters apply, plus the following. All of these parameters are from [1] with the exception of the codec (updated to EFR as this is now most common) and addition of the new GSM bands The GSM configuration of the tests is described below. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results. Page 23 of 64

Previously, permissible error in Tx power and whether the power should be radiated or conducted were not specified. Using PCLs defines these missing variables in accordance with the 3GPP standards. The single mode GSM neighbours list (appendix 1) also applies. Again, care should be taken to ensure no signals are actually present on the neighbour frequencies. Where talk time is band specific the band measured must be specified. 4.2 WCDMA The WCDMA bearer configuration is described below. Some bearer parameters are left to the vendor to decide. In these cases the values used must be reported with the test results. Parameters Value Comment Serving Cell UARFCN (downlink) Band I: Mid Range All bands supported by the handset Band II: Mid Range must be measured.

  27. 27. GSM Association Official Document DG.09 • The method of testing involves averaging over a defined period. A test set must be configured to produce the relevant power for the relevant percentage of that period • Alternatively, depending on the test set, it may be easier to individually measure the current at each power level and average according to the % weighting given. • To ensure that results are always repeatable, the measurements should always be made with the MS moving from minimum power to maximum power. This will minimise any effects due to residual heat in the handset after transmitting at higher power levels 4.3 GSM/WCDMA Dual Mode Device is in GSM dedicated mode, monitoring WCDMA This section is for further study. 4.4 WCDMA/GSM Dual Mode Device is in WCDMA dedicated mode, monitoring GSM. This section is for further study. 4.5 WLAN in conjunction with GSM or WCDMA 4.5.1 VoIP over GAN, GSM coverage available The WLAN, GAN and GSM parameters are the same as the Standby Time test section 3.7 In addition the following network GAN parameters apply: Parameter Recommended Value Comment RTP/UDP packet sample size 20 ms Channel mode Full rate AMR Speech codec rate 12.2 kbit/s WiFi Device Tx level 10 dBm Table 4.4: additional GAN network parameters for VoIP 4.5.2 VoIP over WLAN The purpose of this test is to measure the talk time of the device when using VoIP over a Wi-Fi bearer. For this test the device shall be in WLAN radio coverage only – GSM or WCDMA radio networks are not required. The WLAN parameters for the access point shall be as per those defined in the Standby Time test section 3.7. The recommended parameters for the device as stated in section 3.7 may also be used. In addition to these the following parameters shall also be applied. Page 27 of 64

  29. 29. GSM Association Official Document DG.09 5 PACKET SWITCHED TRANSFER TEST Data transfer tests of various types are defined in later sections; however the principles indicated in this section are also applicable to some of the later described tests. 5.1 GPRS The GPRS configuration of the tests is described below. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results. Parameter Value Comment Hopping On Hopping sequence (900) 1, 30, 62, 93, 124 Hopping sequence (1800) 512, 600, 690, 780, 855 Hopping sequence (1900) 512, 590, 670, 750, 810 Hopping sequence (450) 259, 268, 276, 284, 293 Hopping sequence (480) 306, 315, 323, 331, 340 Hopping sequence (850) 128, 159, 189, 219, 251 Reselection No Rx level -82 dBm Handset Tx Level (900, 850 & Used value shall be reported with (Max, 29 dBm, min) 400) the test results Used value shall be reported with Handset Tx Level (1800) (Max, 28 dBm, min) the test results Used value shall be reported with Handset Tx Level (1900) (Max, 28 dBm, min) the test results Table 5.1a: GPRS parameters for Packet Switched Transfer Where transfer is band specific, the band measured must be specified The single mode GSM neighbours list (appendix 1) also applies. The following parameters are suggested based on observations of real operation. Justifications follow the table. However these are only suggestions. It is recommended that vendors define the test for their most efficient transfer mode. The test results and the channel parameters used to perform the test should all be reported in the last column of the table. Table 5.1b: Additional parameters for Packet Switched Transfer Used value Parameter Suggested value (To be reported) Multi-slot class 12 Handset type 1 Slots (uplink) 1 Slots (downlink) 4 Duty cycle 100% Coding scheme CS4 CS can change No Transfer mode Acknowledged Non Transparent Yes Page 29 of 64 Retransmissions Yes
  30. 30. GSM Association Official Document DG.09 All the GPRS handsets currently available are generally “class 12” or higher. Therefore “class 12” operation (4DL, 1UL slots) has been chosen as the baseline for this test. Type 1 operation has also been chosen as being the lowest common denominator. Other parameters have been selected to represent the handset being used as a modem for download of a large block of data. This choice was made on two grounds: 4. It is an operation that the user will actually perform, and that will occur in much the same way regardless of the user (unlike WAP browsing for example, which is highly user specific) 5. It is relatively easy to set up on test equipment. Acknowledged mode is specified as this is generally used for data downloads. For the same reason non-transparent mode is chosen. Finally the coding scheme with the highest throughput (lowest protection) was chosen and it was decided that this coding scheme would not change (no link adaptation). Note that no retransmissions are supposed to actually happen. The sensitivity or decoding performance of the handset is not measured – no fading channel is specified – the purpose of the tests in this document is to establish the power consumption of the mobile on an ideal (and easily reproducible) channel. In view of this and the relatively high receive signal strength, retransmissions are not expected. 5.2 WCDMA The WCDMA bearer configuration of the tests is described below. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results. Page 30 of 64

Table 5.2: WCDMA parameters for Packet Switched Transfer Page 31 of 64
  32. 32. GSM Association Official Document DG.09 Where transfer is band specific, the band measured must be specified. 5.3 GPRS/WCDMA Dual Model This section is for further study. 5.4 WCDMA/GPRS Dual Mode This section is for further study. 5.5 WLAN WLAN FTP File Transfer In this test we consider a FTP file transfer over WLAN to the handset. The test file shall be located on a dedicated server or PC with network sharing enabled to allow the handset to access the file via the WLAN. Measure the current drain over the period it takes to transfer the file. The size of the file must guarantee a test time of at least 10 minutes. The transferred test file shall be stored on the (external) memory card (or internal hard disk where appropriate). In the event that the handset does not support an external memory card or internal hard disk, the transferred test file shall be stored in the internal memory. The WLAN AP parameters shall be as per Section 3.7 During the test the handset shall be in GSM standby as per Section 3.1 5.6 WLAN/Dual Mode This section is for further study. 5.7 Dual Mode/WLAN This section is for further study. 5.8 Recommendation It is recommended that the results of all the packet switched data tests be expressed as total data transferred rather than time spent in the mode – the data transfer total is a more useful indication to the user of what the handset is capable of and will be very roughly the same regardless of the actual duty cycle seen. 6 CS AND PS SIMULTANEOUSLY CONNECTION TIME TEST This section has been created for further study. Page 32 of 64
  33. 33. GSM Association Official Document DG.09 6.1 WCDMA Simultaneous CS and PS connection can be used for several purposes, but the most common is likely to be data sharing during calls – voice is sent over the CS connection, while data is sent over PS. 6.2 WCDMA/ (GSM/GPRS) Dual Mode Yet again, this scenario is the single mode case of the preceding section with the added requirement to monitor neighbour cells on GSM/GPRS. 6.3 GSM/GPRS CS & PS simultaneously (DTM) This section is for further study. 7 BROWSING TEST The following test simulates Internet browsing operation. It exercises the communications link, the display, and the processor. As per the principles in section 5, the bearer used shall be the most efficient one, and bearer parameters used shall be stated in the test results. 7.1 WCDMA HTML Browsing The GSMA have created a web page containing text and an image that automatically refreshes every 20 seconds. By ‘refreshes’ we mean that the page contains appropriate HTML instructions so as to force the browser to completely reload the page and image every 20 seconds. To execute the test please download the HTML test page and its associated files from the GSM-A website and load it onto your own local web server that is accessible to the handset. The test should not be run from the GSM-A web server because it is not configured to act as a test server. With the handset in WCDMA mode, open its browser, enter the URL of the test page and download the page via the WCDMA network. The complete test page and image should now be automatically refreshed by the browser every 20 seconds until the browser is closed. For the duration of this test, the backlight shall be lit. If this does not happen automatically because of the page update then it must be forced by other means. For example it may be possible to set this in the options, or it can be achieved by manually pressing a key. The method used must be indicated in the test results. Measure the current for 5 minutes as defined in section 19.4. 7.2 GSM / GPRS HTML Browsing The GSMA have created a web page containing text and an image that automatically refreshes every 20 seconds. By ‘refreshes’ we mean that the page contains appropriate HTML instructions so as to force the browser to completely reload the page and image every 20 seconds. Page 33 of 64
  34. 34. GSM Association Official Document DG.09 To execute the test please download the HTML test page and its associated files from the GSM-A website and load it onto your own local web server that is accessible to the handset. The test should not be run from the GSM-A web server because it is not configured to act as a test server. With the handset in GSM mode open its browser, enter the URL of the test page and download the page via the GSM network. The complete test page and image should now be automatically refreshed by the browser every 20 seconds until the browser is closed. For the duration of this test, the backlight shall be lit. If this does not happen automatically because of the page update then it must be forced by other means. For example it may be possible to set this in the options, or can be achieved by manually pressing a key. The method used must be indicated in the test results Measure the current for 5 minutes as defined in section 20.4. 8 STREAMING CONTENT TEST Since the used bearer and transmit power of the terminal is impacting the streaming power consumption, it is recommended that a system simulator is used. In case the system simulator is not connected to the internet, the streaming server provides the required streaming files which can be downloaded and installed on the system simulator. The default setting for the appropriate bearer (see section 5) shall be used. When supported, WCDMA shall be used. 8.1 Video Streaming Terminal devices do support a variety of different streaming formats, which makes it difficult to determine one “default” video stream suitable for every terminal device. Therefore a set of core streaming formats is defined and available on the streaming server as reference content as follows: Bit Rate Frames perProposed Resolution / Size Video Part Audio Part (kbps) second Bearer 128 x 96 176 x 320 x 240 H.263 MPEG4 AMR AAC (SQcif) 144 (QVGA) 12.2 (Qcif) Video 46 15 GPRS X X X Stream 1 Video 50 15 EGPRS X X X Stream 2 Video 77 15 UMTS X X X Stream 3 Video 112 15 UMTS X X X Stream 4 Video 250 15 HSDPA X X X Stream 5 Table 8.1: Set of reference streaming formats Page 34 of 64
  35. 35. GSM Association Official Document DG.09 Standard File Format is 3GPP (usually: file.3gp). The power consumption measurement shall be carried out by selecting and re-playing the stream with the highest possible bit rate with Codec’s, which are supported by the terminal device. If the terminal capabilities are unknown, the test shall be started with Video Stream 5. If this stream does not work, Video Stream 4 shall be used, and so on. The pre-installed Media Player of the terminal device shall be used for Video Streaming. Full Screen shall be enabled, if supported by the terminal device. The Video Stream shall be played using the inbuilt (hands free) speaker of the terminal device. If this is not available, the original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. Test Procedure: Connect to the Reference Content Portal to obtain the video content The actual playing time should be 10 minutes After successfully established connection to the streaming server, start watching the clip Start Power Consumption Measurement The reference content for Video Streams can be retrieved from the GSMA website. 8.2 Audio Streaming Audio Streams are usually only supplied on UMTS Bearers, i.e. this test would only apply to UMTS capable terminals devices only. The following core audio streaming format is defined and available on the streaming server as reference content as follows: Codec Bit Rate Sampling Rate SBR Signalling Audio Stream 1 AAC+ 32 kbps 44.1 kHz 0 (= implicit) Standard File Format is 3GPP (usually: file.3gp). The pre-installed Media Player of the terminal device shall be used for Audio Streaming. The Audio Stream shall be played using the inbuilt (hands free) speaker of the terminal device. If this is not available, the original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. Test Procedure: Connect to the Reference Content Portal to obtain the audio content The actual playing time should be 10 minutes After successfully established connection to the streaming server, start listening to the audio clip Start Power Consumption Measurement Page 35 of 64
  36. 36. GSM Association Official Document DG.09 The reference content for Audio Streams can be retrieved from the GSMA website. 9 APPLICATION SOFTWARE TEST Suggested standard applications are as follows. These have been chosen as the applications most commonly provided on handsets at present. Clearly if a handset does not support the application, the corresponding test is not required. These are activities that do not require active data transfer channel. For these tests the terminal shall be in idle mode as far as air interface activities are concerned (either WCDMA or GSM/GPRS according to the type of terminal). 9.1 Music Playback Terminal devices do support a variety of different music playback formats. Most common use is the mp3 media format. If MP3 is not supported, a reference file shall be transcoded from the mp3 one. The codec used for the test shall be specified in the test results. The following parameters are used for the media file: Bit Rate: 128 kbps Sampling Rate: 44.1 kHz (Stereo) Download the reference music file from the GSMA website and store it onto the handset. The media file shall be stored on the (external) memory card (or internal hard disk where appropriate) and played back from there. Only if the terminal device does not support an external memory card or internal hard disk, the media file shall be stored in the internal phone memory and played from there. The pre-installed Music Player of the terminal device shall be used for music playback. Enabling of screensavers shall be set to the default values as delivered from the factory. The original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. Test Procedure: Save the media file on the phone (memory selection see above) The actual playing time should be 5 minutes Set the volume to mid-level and start listening to the audio media clip Start Power Consumption Measurement 9.2 Video Playback Page 36 of 64
  37. 37. GSM Association Official Document DG.09 Terminal devices do support a variety of different Video Playback formats. Most common use is the MPEG4 Visual Simple Profile Level 0 media format. If this is not supported, H.263 Profile 0 Level 10 shall be used to perform this test. Download the reference video file from the GSMA website and store it onto the handset. The media file shall be stored on the (external) memory card (or internal hard disk where appropriate) and played back from there. Only if the terminal device does not support an external memory card or internal hard disk, the media file shall be stored in the internal phone memory and played from there. The pre-installed Media Player of the terminal device shall be used for Video playback. Background illumination shall be enabled. Screensaver shall be disabled. The original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. Full Screen shall be enabled, if supported by the terminal device. Test Procedure: Save the media file on the phone (memory selection see above) The actual playing time should be 5 minutes Set the volume to mid-level and start watching the video media clip Start Power Consumption Measurement 9.3 Camera Operation The taken pictures shall be stored on the (external) memory card (or internal hard disk where appropriate). Only if the terminal device does not support an external memory card or internal hard disk, the pictures shall be stored in the internal phone memory. Use the terminal under normal light conditions (bright daylight) in a normal illuminated room. Use no external lamps or flashlight and switch off the internal lamp or flash. Picture size/resolution and quality shall be set to maximum. Use the UE in Idle mode. Test Procedure: The reference image to be photographed shall be downloaded from the GSMA website and displayed on a suitable computer screen Start taking photos and store them immediately in the appropriate memory. Take 20 pictures at an interval of 30 seconds Measure the current consumption during the period that photographs are being taken and stored 9.4 Java Game The original stereo cable headset (or one recommended by the terminal manufacturer) shall be used.

  38. 38. GSM Association Official Document DG.09 • Download the Java 3D game applet from the GSMA website and store it onto the handset • Set the volume to mid-level and start the JAVA game • The game should use high quality and 3D graphics, sound and vibrator mode and demo mode to ensure same activities are running during gaming and no need to operate the UE / game • Use the game in Idle mode • Ensure different currents during sound and vibrator activities are covered correctly • Measure the current consumption for 5 minutes as per section 19.4 9.5 Java Music Player The original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. • Download the Java Music Player applet from the GSMA website and store it onto the handset • Set the volume to mid-level and start the JAVA Music Player • Use the Music Player in Idle mode • Measure the current consumption for 5 minutes as per section 20.4 9.6 Video Recording Prerequisites If certain parameter data is not defined by the default factory settings at the factory the measurements shall be made using the setting parameters that the manufacturer assumes will most likely be employed by the users. Mass storage memory is used for streaming video material. If removable mass memory usage is not possible, then saving to the phone's integrated mass memory is acceptable. In the event that the handset has two cameras, the highest resolution (main) camera is to be used for recording. Audio recording shall be on. Video stabilization, if supported, shall be on. If the display is equipped with an illumination function (e.g. backlight), this shall be lit for the duration of the test. If the brightness or contrast of the display is adjustable, the adjustable parameter shall be set at the factory setting when measurement is done. Page 38 of 64
  39. 39. GSM Association Official Document DG.09 If the device under test has an ambient light sensor controlled display, the input of the sensor shall be set to maximum. Keypad lights: default settings. Measurements have to be carried out in a light environment (in the region of 500 lux). Viewfinder on. The highest Video recording quality available on the handset shall be used. Test procedure: A default video file available at the GSMA website shall be played on a PC with medium volume. Enable Video recording on the handset. Capture the video clip as full screen on the viewfinder. Start Power Consumption Measurement The actual recording time should be 10 minutes. Record the Video Recording time and the settings used in Appendices B.1 and B.2 respectively. Note: The PC display refresh rate shall be at least twice the recording frames per second in order to minimise interference. 10 VIDEO TELEPHONY TEST The video telephony is only applicable in WCDMA; the parameters described in section 4.2 are used here. The video telephony call shall be made in Circuit Switched mode and must be bi-directional. Supplementary services shall not be activated. Note: To achieve a bi-directional video call, a second video capable terminal may be used to conduct the test. If so it should be from the same vendor, & be the same type. Codec used is to be specified by the manufacturer. Alternatively, a video loopback may be employed whereby the captured video content is sent back to the terminal. Use bearer data rate of 64 kbps for uplink and downlink (Signalling Radio Bearer: Conversational/ Unknown / UL 64 DL 64 kbps / CS RAB+UL 3.4 DL 3.4kbps SRB for DCCH.). Background illumination shall be enabled. Screensaver shall be disabled. The original stereo cable headset (or one recommended by the terminal manufacturer) shall be used. A default video file available at the GSMA website shall be played on a PC with medium volume. This media file shall be “transmitted” via Video Telephony by both parties or looped back in the case where only one terminal is being used. Test procedure: Page 39 of 64
  40. 40. GSM Association Official Document DG.09 Establish a Video Telephony Call. Make sure video and audio is transmitted properly. Capture the Video Clip as full screen and transmit this as Video Telephony Call to the other party, if used. In the case of video loopback, this should be activated Start Power Consumption Measurement The actual playing time should be 10 minutes The reference content for Video Telephony can be retrieved from the GSMA website 11 BLUETOOTH INTERFACE USAGE TEST This section is designed to test the effect of Bluetooth accessories on the standard operation of a handset. Clearly the tests are only applicable to a handset that supports Bluetooth and specifically supports the accessories indicated in the following subsections. Record the Bluetooth standard version number used on the results sheet. 11.1 Common Parameters Radio environment The interface tested shall be the only Bluetooth connection in the test area. No other radio should be transmitted in the 2.4 GHz band (e.g. 802.11b or 802.11g) Distance (Phone to BT device) 10 centimetres Power Class of the BT device To be stated in the test report Enhanced Data Rate (EDR) Off Sniff interval 0x800 (about 1.28 seconds) Sniff Attempt parameter 8 Sniff Timeout parameter 8 Table 11.1: Bluetooth interface parameters It is recommended to set-up the following scenarios with Bluetooth devices associated with the tested terminal. However the accessory device used must be Bluetooth certified and commercially available. 11.2 Headset – Talk Time This scenario shall be run on top of a Talk Time scenario (ref. chapters 4 or 5). The test shall be run with a commercially available Bluetooth certified headset. In measurement of talk time, a voice signal shall be put through in both directions of the Bluetooth connection. When you have human conversation there are natural breaks in between the words and when that occurs the Bluetooth device goes into sniff mode. If you play music or use a continuous tone generated by a signal generator you don’t get these breaks and the Bluetooth device doesn’t go to sniff mode. Page 40 of 64
  41. 41. GSM Association Official Document DG.09 The test setup will emulate a regular call situation with the headset connected to the terminal under test and a regular voice call open to a second terminal. 11.3 Headset – Music Player This scenario shall be run on top of the Music Playback scenario (ref. chapter 9.1). The test shall be run with a commercially available Bluetooth certified headset. 11.4 PC connection – FTP download This scenario shall be run according to the FTP Download Test scenario (ref. chapter 12) with Bluetooth connection in place of Cable. 11.5 Device in BT discovery mode – Standby Time This scenario shall be run on top of a Standby Time scenario (ref. chapter 3). Bluetooth is enabled on the phone side but remains unpaired with other devices throughout the test cycle. There shall be no other Bluetooth device in range. 11.6 BT data transfer in idle The objective of this test is to measure specifically Bluetooth power efficiency. The test parameters are: Cellular mode: idle, as per the already specified idle mode scenario BT node to handset distance: 1 meter, or use artificial attenuation to achieve the same result File to transfer: GSMA MP3 reference file (as per Music Playback scenario) The results are to be specified as MB Transfer within battery life (as per other data transfer tests). 12 FTP DOWNLOAD TEST For packet transfer modes the useful reference value is the amount of data that can be transferred, not the battery lifetime if performing continuous transfer. The channels defined/suggested in chapter 5 are used to produce a battery life in terms of MB rather than hours. As per the principles in section 5, the bearer used shall be the most efficient one, and bearer parameters used shall be stated in the test results. In this test we consider a file download to an external device (e.g. laptop) connected with a mobile phone via A cable connection Page 41 of 64
  42. 42. GSM Association Official Document DG.09 Bluetooth. During the test using a cable connection, the phone should not be powered by the external device via the cable connection. If this kind of charging cannot be disabled by an appropriate SW tool, the cable FTP test is not relevant.

  45. 45. GSM Association Official Document DG.09 19 TEST METHOD 19.1 General Description The bearer configurations of the tests are described in the previous section. Some bearer parameters shall be selected among some recommended values. These parameters and the selected value shall be reported with the tests results, along with the nominal voltage of the (dummy) battery used for testing. There are 2 measurement methods described in this section. The first method uses a dummy battery and a power supply while the second uses a live battery and measurement circuitry. The former is provided where repeatability is a requirement while the latter is included for backward compatibility reasons. 19.2 Measurement Preparation For the method employing a dummy battery and power supply, please reference 19.2.1 and 19.2.2. For the method employing a live battery, please reference 19.2.3. When using the Dummy Battery Fixture test method, it is mandatory for a conductive RF connection to be used. 19.2.1 Dummy Battery Fixture The dummy battery fixture is a device designed to replace the usual battery pack to facilitate powering the MS from an external DC source and simulating “normal” indications to any active battery management functions within the MS. The dummy battery may consist of a battery pack where the connections to the internal cells have been broken and connections instead made to the DC source. Alternatively it may consist of a fabricated part with similar dimensions and connections to a battery pack and containing or simulating any required active battery management components. The dummy battery should provide a connection between the battery terminals of the MS and the DC power source whilst minimising, as far as possible, the resistance, inductance and length of cables required. Separate “source and sense” conductors may be used to accurately maintain the nominal battery voltage as close to the MS terminals as possible. It may be necessary to include some capacitance across the MS terminals to counteract the effects of cable inductance on the MS terminal voltage when the MS draws transient bursts of current. Such capacitance should be kept to a minimum, bearing in mind that it will affect the temporal resolution of the current sampling. Page 45 of 64
  46. 46. GSM Association Official Document DG.09 19.2.2 Power Source and Current Measurement Device This device performs the combined functions of providing, regulated DC power to the MS and measuring the current consumption of the MS. The power source should support the following minimum set of features: 1. Configurable output voltage with a resolution of 0.01V or better. 2. Output voltage range covering the nominal voltage of the MS battery with some headroom to compensate for voltage drop in the supply cables. 3. Remote sensing to allow the effects of resistance of the supply cables to be compensated for, and to allow maintenance of the nominal voltage at the MS battery terminals. 4. The DC source should have sufficient output current capability, both continuous and peak, to adequately supply the MS during all measurements. Current limiting of the power supply shall not function during a measurement. The following current measurement capability when configured for standby and dedicated mode tests should be met or exceeded: Parameter Idle Mode Requirement Dedicated Mode Requirement Internal Resistance <= 0.1 ohms* <= 0.1 ohms* Sampling frequency >= 50 ksps >= 50 ksps Resolution <= 0.1mA <= 0.5mA Table 19.1: Measurement requirements for Power Supply 19.2.3 Battery Preparation The measure of the battery performance shall be done in optimal configuration. The best battery performances can be obtained by doing a battery cycling, id est. by having the battery fully charged and discharged at least [3] consecutive times. [The cycling method should be described as FFS] 19.3 Standby Test Method using a Power Supply 19.3.1 Configuration If the terminal is WCDMA capable, then the parameters to be used are described in section 3.3 ”Stand by time parameters for GSM/WCDMA dual mode” of this document. If the terminal is not WCDMA capable, but GSM/GPRS capable, then the parameters to be used are described in section 3.2”Stand by time parameters for GSM/GPRS” of this document. If the terminal is GAN capable, then parameters to be used are described in section 3.7 “GAN (UMA) over WLAN / GSM”. Page 46 of 64
