  • 3. 1 11. Network Capabilities 2 1.1- 1.3 Intentionally Left Blank 3 Completed work item. See System Capabilities Guide. 4 5 1.4 Authentication - Incorporation of 3GPP AKA 6 This work item is to incorporate the 3GPP AKA algorithms into the system taking into 7 account any specific requirements of an ANSI-41 evolved network. This will provide 8 for: 9 1.4.1 Enhancements: 10 The 3G system will provide users with a common authentication and key 11 management algorithm for use in all 3G TIA/EIA-41 mapped networks. Enhanced 12 Subscriber Authentication (ESA) will provide the capability for mutual 13 authentication between UIM and network. Key management will ensure that keys 14 for authentication and ciphering are sufficiently independent that compromise of 15 one key does not compromise the other. 16 17 1.4.2 Exportability: 18 The 3G authentication and key management algorithm will meet the requirements 19 of U.S. export laws and regulations. 20 21 1.4.3 Internationalization: 22 This is the ability to permit the use of specific algorithms as may be required on a 23 national or regional basis. It would also provide for the co-existence of multiple 24 algorithms in a mobile station and/or infrastructure to facilitate backward 25 compatibility and roaming capabilities. This capability implies that a mobile station 26 and infrastructure will negotiate the specific algorithms to be used. 27 1.5 Ciphering (circuit switched) 28 1.5.1 Enhancements: 29 Enhanced Subscriber Privacy (ESP) by means of encryption across the air interface 30 protects subscriber traffic (bearer data and signaling) from unauthorized disclosure. 31 32 1.5.2 Exportability: 33 At least one 3G ciphering algorithms will be developed which shall be capable of 34 being used globally. This implies that the algorithm meets U.S. export laws and 35 regulations. This does not preclude the development of algorithms to be used on a 36 national or regional basis. 37 38 1.5.3 Internationalization: 39 Due to restrictions on the use and export or encryption algorithms, it is required that 40 a mechanism be developed to permit the use of specific algorithms as may be 41 required on a national or regional basis. This provides for the co-existence of 42 multiple algorithms in a mobile station and/or infrastructure to facilitate backward 2 2
  • 4. 1 1 compatibility and roaming capabilities. This capability implies that a mobile station 2 and infrastructure will negotiate the specific algorithms to be used. 3 1.6 Intentionally Left Blank 4 Completed work item. See System Capabilities Guide. 5 6 1.7 3G Mobile Equipment Identifier 7 Expanding the ESN field beyond 32 bits. 8 When the length of the ESN is extended, the unique country information should be 9 included in the ESN field. The ESN numbering space should be appropriately divided 10 into a number of subspaces and each subspace is administered by each country. This 11 capability differs from the Expanded ESN effort previously addressed within the TR-45 12 ESN Ad Hoc. 13 1.8 TMSI Support 14 This capability provides for Temporary Mobile Station Identity (TMSI) support in order 15 to mask or hide a mobile station’s subscriber identity from unwanted eavesdropping. The 16 use of TMSI also permits a shortened mobile station address to reduce the size of the 17 messages sent over the air. 18 1.9 Data Field Encoding for Multiple Character Set 19 Support 20 This capability provides the ability to deliver and receive messages from the mobile 21 station in a variety of character sets. Support includes both Short Message Service and 22 other messaging (e.g., Calling Name Presentation) where the information may be 23 presented on the mobile station’s display. The ability to support different character sets 24 includes the ability to assign character sets on a message by message basis as well as the 25 ability to mix character sets within a message. The choice of character set a message is to 26 be encoded in may be driven either by the source information or by the Preferred 27 Language Indicator as the application demands. 28 1.10 Out- of-band Feature Activation/Deactivation 29 Messages 30 Feature activation and de-activation messages provide an out of band mobile station to 31 network signaling procedure for the activation/de-activation, registration and de- 32 registration, and invocation and de-invocation of features. They also provide network 33 level confirmation of a change in a feature back to the mobile station and provide for the 34 capability of a mobile station to query the network as to the status of a feature. 35 1.11 Location - Position Technology Enhanced 36 This capability adds common channel support for position assist parameters passed from 37 the network to the mobile station. This reduces the capacity impact of delivering 38 common parameters to multiple mobile stations. 2 3

See System Capabilities Guide. 3 4 1.13 Automatic Roaming Agreements 5 In the environment where the automatic roaming agreement is supported even if the 6 operator A doesn't have a roaming agreement with the operator B, a user subscribing the 7 operator A can enjoy the operator B's cellular service. This feature may be realized by 8 information transaction other than TIA/EIA-41. 9 Upon registration, the home HLR will be queried and parameter loaded in the visited 10 switch, however it is a business issue to enable the feature where there are no roaming 11 agreements. 12 No additional requirements have been identified. 13 1.14 Intentionally Left Blank 14 Completed work item. See System Capabilities Guide. 15 16 1.15 Backwards Compatibility 17 This standing requirement requires each new version of the specifications to be backward 18 compatible with previous versions, providing for the capability of new mobile stations to 19 work on older systems and for older mobiles to operate on new systems with as 20 consistent set of features as is possible. 21 1.16 Location - Support Services 22 1.16.1 Calling Party Cell/Sector: 23 The ability to transport calling party cell/sector information through the network. 24 1.16.2 Called Party Cell/Sector: 25 The ability to transport called party cell/sector information through the network. 26 1.16.3 Calling Party Latitude/Longitude: 27 The ability to transport calling party cell/sector information through the network. 28 1.16.4 Called Party Latitude/Longitude: 29 The ability to transport called party cell/sector information through the network. 30 1.16.5 Mid Call Location Update 31 The ability to obtain location information for either party while a call is in progress. 32 1.17 Location - Tiered Services 33 Tiered Services provides the ability to identify to the network that a mobile station is 34 within a User Zone (geographical area) and to identify to the mobile station user the 35 name of the User Zone where the mobile station is active via the mobile station display. 36 This allows the Location Based Services capability to provide services such as 37 differential billing, wireless PBX emulation, and residential base station emulation to 38 individuals or groups of subscribers. 2 4
  • 6. 1 1 1.18 Automatic Code Gapping 2 This features allows elements in an ANSI-41 to shed excessive load by instructing the 3 source of incoming requests to suspend messaging for a period of time. 4 5 1.19 All IP Network 6 This project is the development of a network that uses IP based packet data as its primary 7 mechanism for transport and switching. The actual scope of the activity is being defined 8 in a Steering Committee Ad Hoc. 9 102. UIM Capabilities and Services 11 2.1 User Identification Module (UIM) Support – 12 Integrated and Removable 13 The User Identity Module (UIM) contains information specific to an individual 14 subscriber as well as elements required for authentication such as secret keys and 15 algorithms. The UIM functionality can be implemented directly in the MS or via a 16 separate, removable, hardware token. The UIM capability provides for terminal 17 portability within a single subscription based on a single air interface. Combined with 18 the Personal Mobility capability, a UIM should provide portability of services across 19 different MSs and/or different networks (i.e., dual mode international roaming). 20 2.2 Intentionally Left Blank 21 Completed work item. See System Capabilities Guide. 22 23 2.3 Personal Mobility 24 This capability allows a subscriber to roam between different 3G family members (e.g., 25 from cdma2000 to UWC-136, TIA/EIA-41 to GSM MAP) based on either the integrated 26 or removable UIM capability. It provides for the provisioning of all parameters to access 27 the air and network interfaces when moving between families. 283 Data - Circuit Switched Capabilities 29 3.1 V.90 Interworking 30 This capability supports a user’s ability to attach a data terminal device (e.g., laptop 31 computer) to a mobile station and use the wireless network as if it were a V.90 modem. 32 Aspects of this capability include the user’s ability to specify a modem and the airlink’s 33 support of the selected modem’s command set and the sustained bandwidth requirements. 34 3.2 Intentionally Left Blank 35 Completed work item. See System Capabilities Guide. 2 5
  • 7. 1 1 3.3 Analog Async Data to V.90 Speeds 2 This capability allows the transport, over the air interface, of V.90 data signals that are 3 presented to the mobile station as analog signals. The analog signals may be 4 encapsulated/translated as required for transmission over the air interface. An 5 interworking function in the network provides conversion back to the native analog 6 format. 7 3.4 ISDN Interworking 8 ISDN networking is required to achieve the interconnection to ISDN and support 3G 9 mobile station users to communicate to ISDN subscriber directly in circuit switched 10 mode. 11 Required data rates are as follows: 12 1. 64 kbps. 13 2. 128 kbps 14 154. Data - Packet Capabilities 16 4.1 Packet Data Rates 17 The system standards shall support high-speed packet based communications. The bearer 18 capabilities for packet mode are as follows: 19 Packet mode bearers to at least 384 kbps. 20 4.2- 4.5 Intentionally Left Blank 21 Completed work item. See System Capabilities Guide. 22 23 4.6 Multiprotocol support (e.g. X.25) 24 Support for multiple protocols for packet data.(e.g. X.25). 25 4.7 Internet Protocol Version 6 (IPv6) Support 26 Support of IPv6 as per RFC 1883.. 27 4.8 IP Broadcast and IP Multicast Services 28 This is a bearer capability that the network provides single originator - multi terminator 29 communication for packet data communications. Standard IETF multicast/broadcast 30 protocols should be taken into account. 31 Broadcast Services: 32 For broadcast services, the communication terminates to all subscribers on a PDSN 33 or in a particular area. 2 6
  • 8. 1 1 Multicast Services: 2 For multicast services, the communication terminates to all users subscribed to a 3 specific group. 4 These services may be provided via the air interface and/or the packet network per the 5 following. 6 4.8.1 IP Broadcast and Multicast Support at the PDSN: 7 This capability translates IP Broadcast and Multicast messages received at the 8 PDSN into individual mobile specific messages for transport to the targeted mobile 9 stations. 10 4.8.2 IP Broadcast and Multicast Support Over the Air Interface: 11 For broadcast and multicast support the information should be sent over-the-air 12 using common channels to avoid message replication and thereby reduce traffic. 13 When a mobile station is otherwise engaged in a transmission and does not have 14 immediate access to the common channel, it may be required that the message be 15 replicated to reach one or more specific mobile stations. If no multicast member is 16 in a particular cell or sector, the information should not be sent. 17 4.9- 4.10 Intentionally Left Blank 18 Completed work item. See System Capabilities Guide. 19 20 4.11 Optimal Packet Routing 21 Optimal Packet Routing minimizes the number of nodes an IP packet traverses between 22 the mobile and host. This can be supported via the assignment of a Home Agent in a 23 local network. 24 4.12 Prepaid Support 25 This item will extend support for prepaid into packet based services. 26 275. Subscriber Services 28 5.1 Intentionally Left Blank 29 Completed work item. See System Capabilities Guide. 30 31 5.2 User Selective Call Forwarding 32 This feature permits a user to manually redirect, on a per call basis, incoming calls in the 33 alert or call waiting notification states to a network based voice mail system, to a network 34 pre-registered phone number, or to a phone number stored in the mobile station. 35 5.3- 5.4 Intentionally Left Blank 36 Completed work item. See System Capabilities Guide. 2 7
  • 9. 1 1 5.5 Emergency Services 2 Enhanced Emergency Services (ES) permits a subscriber to be connected to a Public 3 Safety Answering Point (PSAP) to request an emergency response from the appropriate 4 agency (e.g., fire, police, ambulance, poison control center, suicide prevention center). 5 The PSAP shall be the PSAP appropriate to the calling subscriber’s current location. An 6 ES call shall bypass any authorization restrictions or call origination restriction features 7 (e.g., Subscriber PIN Access (SPINA), Subscriber PIN Intercept (SPINI) features). ES 8 calls from uninitialized mobile stations shall also be supported. This call may 9 automatically invoke Priority Access and Channel Assignment (PACA) and the call may 10 be given a higher priority than normal calls. Once the ES call is answered, the subscriber 11 shall be able to communicate the type of emergency over a normal voice connection with 12 the PSAP. Air interface encryptions may be used, but the signal at the PSAP must be 13 unencrypted. A subscriber’s ability to activate flash privileges (features controlled by 14 activating the SEND key such as Call Waiting, Three-Way Calling, Conference Calling 15 and Call Transfer) is suspended during an ES call. The only flash privilege exception is 16 in the case where another call was placed on hold to originate the ES call, the mobile 17 station will be allowed to return to the held call while the ES call is still in progress. 18 When the ES call is released, the subscriber’s normal calling capabilities are restored. 19 Release occurs when either the subscriber or PSAP disconnects or when the ES call is 20 dropped. 21 5.5.1 Calling Party Cell/Sector: 22 See 1.16.1. 23 5.5.3 Calling Party Latitude/Longitude: 24 See 1.16.3. 25 5.5.5 Mid Call Location Update 26 See 1.16.5. 27 The Stage-1 for this service is in ANSI-664-A. 28 5.6- 5.10 Intentionally Left Blank 29 Completed work item. See System Capabilities Guide. 30 5.11 Calling Party Pays 31 Calling Party Pays (CPP) permits a wireless subscriber to have some or all air time 32 charges for received calls applied to the calling party. The calling party may be calling 33 from the wireline or the wireless network. 34 The calling party will be given an opportunity to decline the charges. In cases when it is 35 not possible to charge the calling party, an alternative action may be taken (e.g., diverting 36 the call, denying the call, alternate billing, presenting the call to the user with an 37 indication, such as distinctive ringing, that the caller will not be paying for the call). 38 CPP does not impact a subscriber’s ability to originate calls. 2 8
  • 10. 1 1 5.12 Location Based Services 2 Location based services are services that provide different functional features, 3 capabilities, or attributes based on the geographic position or location area of the mobile 4 subscriber using the service. Location based services may be implemented in an 5 IMT-2000 network by using Position Location Technologies or zone determining 6 technologies (e.g., Tiered Services, Non-Public Mode). 7 Location based services allow service providers the opportunity to offer differential 8 billing an selective services based on the subscriber's geographic location when accessing 9 these services. They also allow service providers the opportunity to offer individual 10 subscribers, groups of subscribers, or businesses the ability to utilize private equipment to 11 offer location based services and the ability to restrict access to that equipment to the 12 users of the network. Service providers may also offer subscribers a residential service 13 which is a private system limit to a subscriber's home or a small area surrounding the 14 home. Examples of location based services include such services as Location Based 15 Charging, Fleet and Asset Management, Enhanced Call Routing, and Location Based 16 Information services. 17 See 1.16 for specific location based service support capabilities. 18 5.13 Intentionally Left Blank 19 Completed work item. See System Capabilities Guide. 20 5.14 Rejection of Undesired Annoying Calls 21 This service allows a subscriber to register a directory number of an incoming call as 22 undesirable and annoying after the call ends. Based on this registration, future calls from 23 the same calling party directory number will be denied. 24 5.15- 5.18 Intentionally Left Blank 25 Completed work item. See System Capabilities Guide. 26 5.19 Air Chat 27 This capability allows the real-time transfer of limited amounts of data directly between 28 two subscribers involved in a call. Examples of such data might be a phone number or a 29 phone list. 30 5.20 Intentionally Left Blank 31 Completed work item. See System Capabilities Guide. 32 5.21 Third Party Charging 33 This capability allows all or part of a call to be charged to a third party. 34 If a user does not have credit to originate a voice call, the network will connect a live 35 operator during call origination. The operator may request a credit card number and 36 other information to validate the mobile station and authorize credit. Depending upon the 37 credit limit, the user may make/receive a single call or a series of voice/data calls. The 38 network may restrict services to a geographic area (e.g., city wide) or time duration (e.g., 39 end of business day). 2 9
  • 11. 1 1 For a normal user or a pre-paid user with sufficient credit, the user can connect with a 2 human operator and request third-party billing to override the normal billing for the next 3 call or series of calls. 4 5.22 Intentionally Left Blank 5 Completed work item. See System Capabilities Guide. 6 5.23 Location Dependent Charging 7 Location Depending Charging permits a wireless subscriber to be charged based on the 8 mobile station location. The Location Depending Charging is different than the normal 9 rate charged to the wireless subscriber, it may be higher rate or a lower rate based on the 10 specified geographic areas or zones. When the subscriber is requesting service and is 11 located outside the zones, the service provider may deny access to the services, or 12 provide the services at a different rate. 13 See 1.16 for specific location based service support capabilities. 14 5.24- 5.27 Intentionally Left Blank 15 Completed work item. See System Capabilities Guide. 16 5.28 Calling Information Audio Presentation 17 This capability allow a subscriber upon receiving a call to first hear audio information 18 about the call such as calling party name or number prior to being connected to the 19 calling party. 20 21 5.29 Video Streaming 22 Video streaming services are services in which continuous one way video and audio data 23 are delivered to an end user. 24 25 5.30 Video Conferencing 26 27 5.30.1 Video Conferencing – Two-Party 28 29 Two-party video conferencing services are the services that provide two-way 30 transmission of real-time video, audio and other contents through the wireless 31 communication systems between two parties. 32 33 5.30.2 Video Conferencing – Multi-Party 34 35 Multi-party video conferencing services are the services that provide two-way 36 transmission of real-time video, audio and other contents through the wireless 37 communication systems between two or more parties. 38 39 40 2 10

Over the Air Service Provisioning and 19 Administration (OTASPA) 20 13.1 Mobile Initiated 21 This capability extends the OTASPA capabilities to permit a mobile station to initiate a 22 parameter update. The update may be application or user initiated, for example, to receive 23 an updated Preferred Roaming List after returning from a trip where roaming problems 24 occurred. 25 13.2 User Data 26 This capability extends OTASPA to support user data contained within a mobile station. 27 Examples of user data would be a phone list or stored short messages. This capability 28 permits user data to be uploaded to the network for backup purposes and to be subsequently 29 downloaded to the mobile station for purposes of activation a new mobile station or 30 replacing a damaged unit. The data models for this capability shall support both generic 31 concepts such as a phone list to permit transfers between different mobile station models and 32 manufacturers and vendor specific data that may be unique to a particular mobile station 33 model. 34 13.3 UIM Support 35 This capability extends OTASPA to support both integrated and removable UIM. 36 13.4 Tiered Services 37 This provides support for the Preferred User Zone List (PUZL) in OTASPA. 38 2 15
  • 17. 1 1 13.5 International Band Support 2 This capability will expand the supported bands to include the IMT-2000 band amongst 3 others. It will resolve potential problems where frequency blocks are no longer being 4 assigned consistently on an international basis. 5 6 13.6 Card Application Toolkit 7 The Card Application Toolkit (CAT) provides mechanisms that allow applications, existing 8 on the R-UIM, to interact and operate with any CAT capable ME irrespective of access 9 technology that the ME supports. 10 1114. Data - Support 12 14.1 Data Compression 13 Data compression support in the packet data network includes transparent support of IP 14 network layer compression between the mobile station and the host, compression at the 15 link layer, and TCP/IP header compression (e.g., RFC-1144 Compressing TCP/IP 16 headers for Low-Speed Links by Van Jacobson). This standing requirement exists to 17 insure maximum efficiency over the Air Interface. 18 14.2 Intentionally Left Blank 19 20 14.3 QoS – End to End 21 This activity is to provide an overall architectural and requirements model for the 22 provisioning and delivery of Quality of Service on an end-to-end basis, taking into 23 account the unique characteristics of each of the networks and transports involved. 24 25 14.4 Packet Data QoS Negotiation 26 The access network must support QoS negotiation per connection based on radio 27 resources and mobile station capabilities. 28 14.5 Packet Data QoS Parameters 29 QoS parameters allow differentiated services, whether the parameters are in the air 30 interface or system wide. 31 Initial - The initial set of parameters allow different priorities to be established between 32 applications and subscribers for basic IP transport. 33 Enhanced - The enhanced set of parameters support services such as video streaming and 34 conferencing. 35 14.6 Quality of Service Negotiation - During a Call 36 This capability would provide for dynamic provisioning of Quality of Service Parameters 37 as determined by either the application or the mobile station subscriber. 2 16
  • 18. 1 1 2 14.7 Quality of Service - User Selection 3 This capability permits a user to select Quality of Service Parameters from the mobile 4 station 515. Codec 6 15.1 Vocoder Tandem Free Operation (VTFO) 7 VTFO permits the bypass of speech encoding and decoding in the network for mobile 8 station to mobile station calls when the same digital codec type is used over the radio 9 interfaces serving the calling and called party. Vocoder bypass reduces throughput delay 10 produced by the tandeming of vocoders and may improve audio quality. This capability 11 includes both inter-BSC (intra-MSC) and inter-MSC operation. 12 Description needed for enhancements. 13 15.2 Selectable Mode Vocoder 14 This vocoder will provide for equivalent and/or improved voice quality when compared 15 against EVRC at a reduced average bit rate. It will provide for operator selection of 16 operating modes to trade off average bit rate vs. voice quality. 17 15.3 High Quality Audio Codec 18 A high quality audio codec would provide a quality level for audio transmission that far 19 exceeds current codecs that are tailored for voice. Such a codec would have increased 20 input bandwidth capability, wider dynamic range and may have multi-channel 21 capabilities such as stereo and/or surround sound. 22 23 15.4 Intentionally Left Blank 24 25 2 17
