  • 75. Video Call Quality Index • Anite has developed an algorithm called the VQI (Video Quality Index) to assess the quality of video calls. The VQI is intended for measuring the downlink video quality of video telephony calls. It is a non-intrusive, proprietary algorithm; built upon the fact that most of the video quality degradation is caused by errors in data transmission. The VQI is calculated in real-time during the measurement with Nemo Outdoor, and stored into the log file along with standard network parameters and signalling. • The VQI algorithm is based on H.233 metrics, such as H.233 Frame Error Rate (FER) and H.233 frame rate monitored from the 3G-324M protocol stack of the handset. Subjectively graded video material, collected in extensive test campaigns in various live 3G networks, has been compared to H.233 metrics to build an algorithm that translates these errors into a video quality index value. • Video call quality measurement are supported with Motorola 3G terminals (V3xx, V9)
  • 76. Voice Quality Measurements, Mobile-to-Mobile • The measurement is based on the ITU-T recommendation P.862.1 & 862.2 and it produces a PESQ score that is mapped on a EMOS (Estimated Mean Opinion Score) scale
  • 77. Voice Quality Testing, Fixed-to-Mobile
  • 78. Voice Quality Testing, Test Samples • Length 3 to 10 seconds • 16-bit linear, 8Khz sampling rate wave files (Narrow band) • 16-bit linear, 16Khz sampling rate wave files (Wide band) • Speech and only speech • Speaker’s language, gender and age are quite irrelevant
  • 79. Voice Call/Voice Quality Settings • Number defines the number to be called. It must be a valid phone number. • The Voice Quality check box activates the voice quality settings. • Reference sample filename defines the reference sample to which the received audio sample is compared. • Prefix for received sample files refers to the prefix that is added to the file names of received audio sample files. If you leave this field empty, the received audio files are not stored. For example: terminal1_34_15112004_143045.wav. • Save only samples below threshold determines the value below which the samples are saved. • Call duration determines the time that the call lasts in seconds. The duration timer is started from the channel assignment. The range of duration values is from 1 to 1,000,000 seconds. • Call attempt timeout value determines the maximum duration of the call attempt.

Requires option 315017-00 (GSM/WCDMA or 315017-01 WCDMA only) • Data Mode defines the type of measurement data computed from each sample. Note that the available selection depends on the scanner type
  • 95. Nemo Outdoor – WCDMA Scanner Settings Measurement Mode defines whether frequency scanning or pilot scanning is used. For Anritsu scanners, only pilot scanning is available. Network Name field can be used for stating the friendly name for the network (operator) that Nemo Outdoor measures with the respective test device, for example, Sonera, A1, and DTX. Note that you should enter the name yourself, as Nemo Outdoor does not recognize the network that each device is using. The network name is presented in the output files and helps you to recognize which network you have been monitoring. Channel Style refers to the style of the channel. For UMTS scanners, the options are Narrow Band (200kHz) and Wide Band (3.84MHz). For Anritsu scanners, only Wide Band is available. By clicking the Channel Configuration button, you can access the Select Channels dialog. See section Channel Configuration on page 67 for detailed information about configuring channels. Measurement Period defines the time in milliseconds for which the scanner measures and then reports the result. The result reported is calculated according to settings defined in the Channel Configuration dialog. Anritsu specific
  • 96. Nemo Outdoor – WCDMA Scanner Settings TOP-N mode check box enables/disables TOP-N scrambling code scanning. If enabled, scanner will report results from N best scrambling codes. PcTel scanners support only TOP- N mode returning max. 32 pilots. With Anritsu it’s possible to measure/ log all 512 pilots as well Number of scrambling codes field defines how many scrambling codes are reported by scanner in TOP-N mode to improve on the accuracy of radio propagation models High Speed mode makes it possible to acquire more samples (max 32 pilots per channel), (Ec/N0 -21.5dB) while in High Dynamic mode offers fewer samples (max 16 pilots per channel) with a larger dynamic range Ec/N0 -26 dB) Data Processing Method defines how the scanned data is processed by the scanner. In aggregate method, the sum of all peak pilot Ec/Io values above the PN threshold is calculated. If there are no peaks above the PN threshold, value -30 dB is returned for WCDMA. With Peak method Peak pilot Ec/Io value is recorded. Aggregate Ec/Io is calculated in +/- 25 chips window from the Peak Ec/Io by aggregating all the Ec/Io components that cross user supplied PN Threshold.
  • 97. Nemo Outdoor – WCDMA Scanner Settings CPICH Ec/N0 Threshold defines the power that is included to find delay spread. Number of fingers defines the maximum number of fingers used for RAKE in measurement. Number of delayed CPICH peak components (inside the search window) each independently Decoded. Max. is 50, but it is not exactly "rake fingers" as there is no rake receiver, but a maximum of 51 multipaths are handled. Not supported with Pctel scanners at the moment Rake threshold determines a valid path (in dB). Subtracting the set value from a path with a maximum correlation value gives the lower limit of the valid path. (Anritsu) Pilot sampling ratio option is available for WCDMA pilot scanning mode and for PCTEL EX scanners only. The available options are 1:1, 1:2, 1:4 and 1:8. With ratio 1:1 all samples (Pilotscan events) are logged, with ratio 1:2 every second sample is logged, with ratio 1:4 every 4th sample is logged, and with ratio 1:8 every 8th sample is logged. By decreasing the sampling ratio you can decrease the output file size, but the scanning accuracy will be diminished
  • 98. Nemo Outdoor – WCDMA Scanner Settings P-SCH defines if the selected scanner will measure the P-SCH Ec/N0 and RSCP values for each scrambling code. S-SCH defines if the selected scanner will measure the S-SCH Ec/N0 and RSCP values for each scrambling code. Time of arrival is defined as the measured difference between the expected arrival time (GPS time) and the actual arrival time of the maximum peak above the PN threshold. It is reported in chips or half chips. Position of a selected pilot (Scrambling Code) in chips from the internal 1/100th second time mark that is aligned with GPS time if GPS signal is present. Ranges from 0 to 38399. If pilot is not detected 38400 is returned.
  • 99. Nemo Outdoor – WCDMA Scanner Settings Delay spread defines if the selected scanner will also measure the delay spread value (in chips) for each scanned scrambling code. Delay spread is determined as the difference between the last and first component to break the threshold set in PN Threshold. SIR (signal to interference ratio) defines if the selected scanner will measure the SIR value for each scrambling code. Co-channel interference or CCI is crosstalk from two different Base Stations/Sectors reusing the same frequency channel. There may be several causes of CCI such as: frequency planning issues, inaccuracies in propagation models, weather conditions etc. This will cause the signal to travel much further than intended or in ways not predicted often causing interference to local transmitters in the areas affected by the increased range of the distant Base Station. CPICH SIR Measurement is quantifying the interference. (Peak Pilot Ec)/(Aggregate of Peak Ec from all Interfering Pilots).
  • 100. Nemo Outdoor – WCDMA Scanner Settings Finger check box enables and disables Finger measurements for the scanner. Rake receiver approach in general is used to counter the effects of multipath fading. Each delayed component independently decoded when combined by a receiver (for example mobile phone) may result in better Signal to Noise Ratio compared to “clean” environment (Anritsu) SIB decoding option is available for Anritsu and PCTEL EX scanners. When the option is selected, SIB messages (SIB 1-18) are written in the log file. Note that when SIB decoding is selected and more than one WCDMA carriers are scanned, it will affect the scanning of other carriers and slower down the scanning rate When the Neighbor list decoding option is selected, the NLIST (neighbor list) event is written in the log file for both GSM and WCDMA. When the Missing neighbor detection option is selected, the missing neighbor information event (NMISS) is written in the log file. You can view the missing neighbor information, for example, in a grid view. Requires SIB decoding option Uplink interference check box enables and disables uplink interference decoding for the scanner. Available for scanners that support BCH demodulation (Anritsu)

Note that this functionality is available for certain GSM and GSM/UMTS dual-mode mobiles only.
  • 104. Cell Testing • The surrounding cells of a location can be tested through an automated list of test calls that are locked to a cell at a time • Also called ”sleeping cell detection”. UE is automatically locked to neighboring cells and the test call is made. • Useful also in high traffic areas as surrounding cells can be tested from one location • Test cases: – Voice call, packet call or both – Adjustable RX level and Ec/N0 thresholds • Results can be stored in a file • Test results seen also in the UI
  • 105. GSM/WCDMA Forced Handovers (Only with SAGEM and Nokia terminals) • HO forcing 2G- 2G, 3G- 3G • BCCH/ ARFCN must be defined • UARFCN and Scr. Code must be defined • UE makes single HO to specified cell, returns back to the original cell
  • 106. GSM Forced Handovers (Only with SAGEM and Nokia Terminals) BCCH ARFCN • Define channel where you want to make the HO Normal mode • Forcing disabled Handover forcing • Handover forcing enabled Handover suppression • Stops making handovers
  • 107. Measurement report message modification with Nokia UE’s (3G) • Measurement report message modification is done by enhancing the current UMTS HO forcing functionality. Handover/ Handoff control can be accessed during a voice call • There are three different mode request commands : Normal mode, Handover Suppression, and Handover Forcing. If the terminal accepts the command, the corresponding button in Nemo Outdoor user interface will indicate this. If the command fails, this is notified as well. It is also possible to send the same command several times without clicking other commands (i.e. send a new Handover Forcing command with different bias values or forced UE to different scr. code, or in GSM to a different channel without first deactivating HO forcing. Example: the UE can be forced to scrambling code 6. Once the UE is locked to scrambling code 6, the user can set a new target cell and press the Handover forcing button again. • During normal mode forcing is disabled and the device makes 2G and 3G handovers normally.
  • 108. Measurement report message modification with Nokia UE’s (3G) II • Once target cell settings including biasing information are defined by the user, the handover mode can be changed to Handover forcing mode by pressing the button. Handover forcing is done by biasing target and non-target cell Ec/N0 and RSCP values. Therefore, it is also possible to bias current active cell. For example, in the example below active set includes only one scrambling code. By pressing the Handover forcing button UE reports biasing Ec/N0 and RSCP values as set by the user. When the mode is changed back to normal mode, the UE starts reporting unbiased values.

Conditional Scripting (2) • Example: FTP download with multiple usb modems • Idea is to make such a script file where FTP DL is done several times without PDP context deactivation command • In case PDP context is dropped device should make automatically new PDP context activation followed by FTP DL transfer • First open existing script file or make a new one • Conditional scripting based on packet statenotifications, e.g., “wait until system change to UMTS until start a new call”
  • 160. Conditional Scripting (3) • Under Loop settings select “Repeat the loop as long as the following criteria are met” and press “Field” button • Select GSM/ GPRS/ Packet state
  • 161. Conditional Scripting (3) • Select “4: Packet session active” for value. • Loop is now repeated as long as packet session is active • Press ”Add to list” button and then press ok
  • 162. Conditional Scripting (4) • Loop commands appear to the list and next step is to move loop commands to correct lines • Highlight ”Loop as long as... ” And move it after PDP context activation • Highlight ”End Loop” and move it to after Stop FTP transfer line • Now device will make PDP context activation followed by FTP download data transfers. After FTP data transfer new data transfer is made after wait time (5s) • In case PDP drops new PDP context activation is made automatically
  • 163. Conditional Scripting (5) • Idea is to make one long voice call only in UMTS. After inter system HO to GSM call must be stopped. New call is made only when system is UMTS. Calls are not allowed while in GSM • Line 1: Loop as lond as serving system is different than UMTS • Line 3: Voice call start. Duration set to only 3 seconds • Line 4 and 5: Script is running in the loop as long as system is UMTS (5) • When system is different than UMTS call is ended
  • 164. Script groups & synchronization • Script groups are useful especially if certain devices and script files are needed to be synchronized • Synchronization points can be added to script files as many as needed. It should be noted that number of synchronization points between script files used in the same script group should be equal.
  • 165. Missing Neighbor Detection
  • 166. Missing Neighbor Detection (2) • Based on comparison of scanner and mobile measurements OR • Scanner receiver only if scanner includes optional SI and SIB decoding OR • Using terminal only if terminal is capable of doing also scanning. (Available with Nemo Outdoor 5.2 onwards) • Each cell has list of neighbouring intra-frequency, inter-frequency, and inter-system cells • Terminal sees (measures) only cells in the neighbour list • Scanner measures all available cells regardless of any neighbour lists • Missing neighbour detection is based on comparing scanner measurements to the neighbour list of the mobile • Possible missing neighbor: cell that is not in the neighbourl ist of the mobile at given time, but is seen (measured) by the scanner Missing neighbors measured by scanner Neighbourlist of the serving cell as seen by the terminal, SCRs 72 and 73 are not in the list New site, cells not added to the neighbourlists of the surrounding cells and vice versa
  • 167. Missing Neighbor Detection (3) • Missing neighbor: the missing cell is adjacent to the serving cell, and equal or stronger levels are measured compared to the serving cell – Fix: Update neighborlist • Overshooting: the missing cell is not adjacent to the serving cell, it was not planned to be strong in the measured location – Fix: downtilt the missing cell, or otherwise improve the cell isolation • Not a problem: the missing cell is not adjacent to the serving cell, and is fairly weak compared to the serving cell
  • 168. Missing Neighbor Detection (4) From the Control menu, select Missing Neighbor to open the following dialog box. The field displays the GSM/ UMTS scanner used. Click Enable to start the missing neighbor detection. • Available for both GSM and UMTS. • No need for neighbor list info in BTS file.
  • 169. Missing Neighbor Detection (5) • Missing neighbor detection using only scanner receiver • Support for GSM SI and UMTS SIB message decoding with Anritsu, PcTel EX and R&S scanners . • By selecting ”System Information decoding”, L3 messages are written in log file • By selecting ”SIB decoding”, SIB messages are written in log file • By selecting “Neighbor list decoding” NLIST event is written in log file for both GSM and WCDMA • By selecting ”Missing neighbor detection”, missing neighbor information is written in log file (NMISS event). Missing neighbor information can be seen e.g. on table grid
  • 170. GSM Missing Neighbor Detection using Nokia Terminal • With single shot scanning results possible missing neighbors can be seen during the measurement in the event view as the result is only a snapshot from one time stamp. During playback the same information can also be seen when using the bar graph view • Missing neighbor cell names can be shown as well in different views • With continuous scanning mode it is not recommended to use missing neighbor detection as signalling messages are decoded at the beginning of the scanning
  • 171. UMTS Missing Neighbor Detection using Nokia Terminal • CPICH RSCP threshold can be adjusted by the user. Scr. codes below the threshold value are not measured • By enabling ”Missing neighbor detection”, possible UMTS missing neighbors can be detected. With continuous scanning mode it is not recommended to use missing neighbor detection as signalling messages are decoded at the beginning of the scanning and this can lead to incorrect missing neighbor detection • From channel configuration UMTS carriers can be selected
  • 172. UMTS Missing Neighbor Detection (2) • Example of possible UMTS missing neighbors with indoor measurement • Scr. codes #209 and #243 are detected as possible missing neighbors with high Ec/N0 values causing also interference to active pilots • Location where missing neighbors were detected is shown on the indoor map • Cell names for the missing neighbors shown on the event view
  • 173. UMTS Pilot Pollution Analysis • UMTS Pilot pollution analysis – Pilot pollution analysis can be done real time using UE or scanner receiver – Pilot pollution analysis is made on based CELL MEASUREMENT events and analysis is always active – User can define thresholds for pilot pollution analysis via user interface. Pilot pollution is detected when all criterias matches. • Ec/N0 active set best below threshold: Default value set to - 12dB. Pilot pollution analysis is done when best reported active set Ec/N0 value is below -12dB • RSCP active set best above threshold: Default value set to - 95dBm. Pilot pollution analysis is done when reported active set best RSCP value is above -95dBm • Polluter level window from best active set cell: Default value set to -6dB. Pilot pollution analysis is done when Ec/N0 value of polluting pilots are within -6dB from the best active set Ec/N0 value • Pilot count threshold: Default value is set to 3. Number of cells that are within the user defined window from the Ec/N0 of active set best cell. Pilot count includes active and monitored sets. E.g. Pilot pollution analysis is done when more than three pilots are detected within the user defined window from the Ec/N0 of active set best cell
  • 174. UMTS Pilot Pollution Analysis • UMTS Pilot pollution analysis – Pilot pollution analysis results are written to log file as a own event called ”CELLPOLLUTION” – Event includes the following information: • Source system • Source band • Source ch number • Pilot pollution scr code • Pilot pollution Ec/N0 • Pilot pollution RSCP • Cell name of polluting pilot (if cell site file is used) • Cell ID of polluting pilot (if cell site file is used) *) cell site file not used with scanner devices at the moment
  • 175. UMTS Pilot Pollution Analysis • UMTS Pilot pollution analysis based on scanner measurements • Ec/N0 values for pilots are less than -12dB • Ec/N0 values of the pilots are within -6dB from the best Ec/N0 value • Ec/N0 and RSCP values for the strongest polluting pilot can be seen on the map
  • 176. UMTS Pilot Pollution Analysis • UMTS Pilot pollution analysis – Pilot pollution analysis is made based on previous CELLMEAS events what are already measured and written to log file. CELLMEAS events are updated also during pilot pollution analysis. Due to this reason pilots listed in the pilot pollution event have different Ec/N0 and RSCP values than for the current pilots in the active/ monitored sets
  • 177. UMTS Pilot Pollution Analysis • UMTS Pilot pollution analysis – Brown bar graph is for active set Ec/N0 (-17.4dB) – (CH 10837, scr. code 40). Value is the present value taken from CELLMEAS event at 11:35:37.266 – Blue bar graph. The same scr. code is listed as polluting pilot but with different Ec/N0 value – (-18.1dB). Value is taken from CELLPOLLUTION event at 11:35:37.266. – Pilot pollution analysis was triggered at 11:35.37.108 – (active set Ec/N0 -18.1dB)
  • 178. GSM interference analysis • GSM co-channel and adjacent channel analysis is done real time during the measurement and playback with Nemo Outdoor. The user must enable interference analysis similarly to e.g. with missing neighbor detection. Interference detection is done based on GSM terminal and GSM scanner measurements and these measurements are combined together. GSM terminal continuously reports RX level, RX quality and C/I values. With RX level and RX quality, the sub values are used to make correct analysis in case DTX downlink is used
  • 179. User Parameters • User-defined parameters from signaling • User-defined string is searched from decoded messages, and the following value is returned • Parameter can be displayed in info view and graph side panel • User parameters can be seen also exported from event grid
  • 180. Exporting Measurements • Exporting Nemo measurement file to MapInfo tab file format or to .csv formats – Open measurement file – Open event view and select parameters (drag and drop) to be exported – Right click and select all from menu. All lines are now highlighted – Select save -> Mapinfo tab file, csv or other format for export file
