4 x Bearer Service Negotiation and Teleservice x.1 SMG project UMTS Radio Access GSM Radio Access x GSM-UMTS Core Network UMTS Services x.2 Linked work items x.3 Justification UMTS TS «Services and Service Capabilities» identifies the service capabilities provided by UMTS which allow the creation of new and innovative applications. These building blocks are the teleservices, the bearer services and the service features. Teleservices and bearer services may be requested from any originating point in the network, typically either the mobile station, a server or an interworking gateway with other networks. For connection oriented bearer services, negotiation shall be possible at bearer set-up and re-negotiation after bearer set-up. In order to ensure backward compatibility with GSM, and support for UMTS services in legacy networks, the negotiation procedure used to set-up/modify these services should also be able to adapt and operate over legacy networks (GSM, fixed network etc). Transport mechanisms shall support the teleservices and bearer services in the UMTS core network. API and control protocols are required to setup/negotiate/re-negotiate the teleservices and bearer services. This is the purpose of this work item. This work item is a UMTS phase 1 work item. x.4 Service Aspects This work item proposes the creation of the API and control protocols which shall be used by network elements (typically Mobile Station, Server or Gateway) to set-up teleservices, to negotiate at set-up and re-negotiate after set-up bearer services, as well as the transport mechanisms to support the teleservices and bearer services in the UMTS core network. For teleservices : Speech: A default speech codec will be specified to provide speech service across the UTRAN and GSM access networks. The selected speech codec will operate with no discernable loss of speech on handover between the GSM access network and the UTRAN. Short Message Service: A short message service will be provided seamlessly (as far as the user or her terminal equipment is concerned) across the UMTS and GSM access network. Additional features are planned for SMS in Release 99. Facsimile: Transfer of data to/from facsimile machines in the PSTN/ISDN should be supported seamlessly (as far as the user or her terminal is concerned) across the UMTS and GSM access network. It is envisaged that the main use of fax in the mobile environment will be via PCs. UMTS will not support direct end-to-end communication using T.30.Instead a store and forward service is envisaged where some kind of file transfer program is used to transfer text or images to a store and forward unit for subsequent delivery to the facsimile machine in the PSTN/ISDN. The user (or her PC) may receive notification of successful delivery of the fax.. No standardisation of a fax store and forward service is planned and it is envisaged that roaming subscribers will be supported via the VHE. Circuit switched data: Circuit switched data services and "real time" data services will be provided for interworking with the PSTN/ISDN so that the user is unaware of the access network used (UMTS and GSM access network or handover between access networks). Both transparent (constant delay) and non-transparent (zero error with flow control ) services will be supported. These data services will operate with minimum loss of data on handover between the GSM access network and the UTRAN. For bearer services : 1. The phase 1 UMTS core network shall support circuit switched data service capability of at least 64 kbit/s per user. This shall not limit the user from choosing lower data rates. 2. The phase 1 UMTS core network shall support packet switched data service capabilities of at least 2 Mbit/s peak bit rate per user. This shall not limit the user from choosing lower data rates. 3. The phase 1 UMTS core network shall allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics. It shall be possible to apply traffic policy (e.g. connection admission control, flow control, usage parameter control...) on a connection during its set-up and lifetime.

5 4. The phase 1 UMTS core network shall support a range of traffic and performance characteristics for the connectionless traffic. 5. The range of traffic and performance characteristics that shall be supported by the phase 1 UMTS core network for connection oriented and connectionless traffic shall be at least those of GPRS phase 2+ release 99. This means that the support of the full set of bearer services defined in Annex 1 sections 3 and 4 is not required for the phase 1 UMTS core network. 6. Point to multipoint communication configurations as defined in Annex 1 shall be supported by the phase 1 UMTS core network. 7. The phase 1 UMTS core network shall allow one mobile termination to have more than one connection mode (connection oriented and connectionless traffic) and/or more than one connection simultaneously. It shall be possible for each connection to have independent traffic and performance characteristics. It shall be possible for each connectionless message to have independent traffic and performance characteristics. 8. In order to facilitate the development of new applications, it shall be possible to address applications to/from a phase 1 UMTS mobile termination in connection oriented and connectionless traffic modes (e.g. the notion of Internet port). 9. Support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes. x.5 MMI-Aspects None identified. x.6 Charging Aspects The charging aspects are covered in the UMTS Charging & Billing work item. x.7 Security Aspects All the authentication procedures must have been followed before the mobile can request and negotiate a teleservice or a bearer service. The UMTS Access Security work item covers the security aspects. x.8 Impacts Affects: USIM ME NW Others Yes x x No x Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release x.10 Work item rapporteurs x.11 Supporting companies Motorola, FT, Ericsson, MMO, Siemens, T-Mobil, Fujitsu, Lucent. x.12 Responsible STC(s) Prime : SMG3 & SMG4 Secondary : SMG1 & SMG12 x.13 Others

6 x UTRAN Bearer Capabilities x.1 SMG project x UMTS Radio Access GSM Radio Access GSM-UMTS Core Network UMTS Services x.2 Linked work items x.3 Justification UMTS TS «Services and Service Capabilities» identifies the broadband transport and bearer control capabilities of UMTS. UTRAN is the new access network defined in UMTS for supporting these broadband bearer capabilities in the access part of the UMTS network. UTRAN transport and control protocols shall be specified to fulfil UMTS TS requirements. This is the purpose of this work item. This work item is a UMTS phase 1 work item. x.4 Service Aspects This work item proposes the creation of transport and control protocols in the UTRAN to fulfil the following requirements : 1. A UTRAN shall be contained within only one UMTS network. (In the case of a network with a phase 1 UMTS core network consisting of both a GSM NSS and a GPRS backbone, it shall be possible to connect the UTRAN to the two types of infrastructures.) 2. The UTRAN shall support the set-up, re-negotiation and clearing of connections with a range of traffic and performance characteristics. The re-negotiation may result from an upper layer request or a change in the radio conditions (handover, cell load modification,...) and may be mobile station or network initiated. It shall be possible for the UTRAN to apply connection admission control during connection set-up and re-negotiation (Connection admission control is a network procedure used to limit the admission of new connections to those which do not compromise the traffic and QoS characteristics of the already established connections). It shall be possible for the UTRAN to apply flow control on a connection during its lifetime (Flow control is a network procedure used to regulate the traffic of a user). It shall be possible for the UTRAN to apply usage parameter control on a connection during its lifetime (Usage parameter control is a network procedure used to check that the traffic contract negotiated between the user and the network is respected by the user). 3. The UTRAN shall support a range of traffic and performance characteristics for the connectionless traffic. 4. The range of traffic and performance characteristics that shall be supported by UTRAN for connection oriented and connectionless traffic is indicated in Annex 1 sections 3 and The UTRAN shall allow one mobile termination to have more than one connection mode (connection oriented and connectionless traffic) and/or more than one connection simultaneously. It shall be possible for each connection to have independent traffic and performance characteristics. It shall be possible for each connectionless message to have independent traffic and performance characteristics. 6. Seamless handover of active connection oriented and connectionless traffic from one single mobile termination between cells of one UTRAN shall be supported. This shall result in an imperceptible loss of speech (if any) for the user of telephony services and data services with no degradation of QoS. 7. At least one Class Mark shall be standardised for mobile terminals supporting both WCDMA and TD-CDMA radio interfaces. It shall support monitoring of the two types of cells in idle mode (cell reselection procedure) and active mode (handover preparation procedure). 8. For UMTS networks composed of UTRANs with both WCDMA and TD-CDMA radio interfaces, the cell selection and the paging procedures shall accommodate to the fact that service areas may be either covered by WCDMA cells, WCDMA and TD-CDMA cells or TD-CDMA cells.

7 9. Handover of one mobile termination connection oriented and connectionless traffic between cells of two UTRANs using different radio interfaces (i.e. WCDMA and TD-CDMA) and operated by one single UMTS network operator shall be supported in both directions. SMG1 seeks SMG2 advice on whether it is technically and cost effectively feasible for this type of handover to be seamless. 10. The UTRAN shall facilitate determination of the location of a UMTS mobile termination. It shall be possible for the location precision to be a UMTS network operator choice, with the precision of the location varying from one part of the service area to another. It shall be possible to achieve a minimum precision of around 50 meters in all types of terrestrial radio environments. Location requirements are detailed in TS section The UTRAN shall support Localised Service Area (LSA)-concept. It shall facilitate user dependent radio resource selection based on LSA (e.g. when user is located at his office, radio coverage provided with indoor radio solutions should be preferred). Corresponding GSM feature has been specified in GSM The optimisation of the UTRAN radio interface shall be done around the objectives expressed in TS section Standardised protocols shall be defined for the operation, administration and maintenance of each of the UTRAN component in UMTS phase 1 in cooperation with ETSI TMN. 14. The USIM requirements defined for later releases of UMTS should be taken into account in the design of UTRAN (if having any impact). x.5 MMI-Aspects No MMI aspects. x.6 Charging Aspects No charging aspects. x.7 Security Aspects No security aspects. x.8 Impacts Affects: USIM ME NW Others Yes x x No x Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release x.10 Work item rapporteurs x.11 Supporting companies Motorola, FT, Ericsson, MMO, Siemens, T-Mobil, Fujitsu, Lucent. x.12 Responsible STC(s) Prime : SMG2 Secondary : SMG1 x.13 Others

8 x UTRAN and GSM BSS Relationship x.1 SMG project x UMTS Radio Access GSM Radio Access GSM-UMTS Core Network UMTS Services x.2 Linked work items x.3 Justification UMTS TS «Services Principles» identifies the special nature of the relationship between the UTRAN and GSM BSS access networks. It is expected that UTRAN will start as islands in a sea of GSM BSS. GSM BSS will be a key to service continuity in UMTS networks. It shall be possible for a network operator operating a UMTS network composed of UTRANs and GSM BSS access networks to manage the mobility (including handover) of dual mode mobile stations. This is the purpose of this work item. This work item is a UMTS phase 1 work item. x.4 Service Aspects This work item proposes the support of resource and mobility management between UTRAN and GSM BSS access networks in line with the following requirements : 1. At least one Class Mark shall be standardised for mobile terminals supporting the GSM BSS and UTRAN radio interfaces. It shall support monitoring of cells belonging to the two types of access networks in idle mode (cell reselection procedure) and active mode (handover preparation procedure). 2. For UMTS networks composed of both GSM BSS and UTRAN access networks, the cell selection and the paging procedures shall accommodate to the fact that service areas may be either covered by GSM BSS cells, UTRAN cells or both. 3. For UMTS networks composed of both GSM BSS and UTRAN access networks, handover shall be supported between GSM BSS and UTRAN cells of connection oriented and connectionless traffic, in both directions (i.e. UTRAN to GSM BSS and GSM BSS to UTRAN). Some traffic flows may be re-negotiated, temporarily released or re-established during these handover procedures because of the different bearer capabilities of the GSM BSS and UTRAN access networks. A detailed list of handover requirements needs to be defined service per service by SMG1 (i.e. for all GSM phase 2+ release 99 bearer services, teleservices and supplementary services). x.5 MMI-Aspects No MMI aspects. x.6 Charging Aspects No charging aspects. x.7 Security Aspects No security aspects. x.8 Impacts Affects: USIM ME NW Others Yes x x No x Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release 1999.

10 x UMTS Mobility Management x.1 SMG project UMTS Radio Access GSM Radio Access x GSM-UMTS Core Network UMTS Services x.2 Linked work items UMTS Access Security. x.3 Justification The purpose of the work item is to define the necessary functions and protocols for network selection, mobility management inside a UMTS network, roaming between UMTS networks, as well as roaming between GSM and UMTS networks. This work item is a UMTS phase 1 work item. x.4 Service Aspects The work item shall define the necessary functionality for: - Network selection - User registration and de-registration on a UMTS network - Location management, including automatic updates - Both bilateral and automatic roaming agreements between UMTS networks with improved security as defined by SMG10. The following roaming scenarios shall be supported by a UMTS network: - Roaming between UMTS operators - International/Global Roaming with IMT2000 operators - Roaming in GSM networks shall be possible for the standardised classes of UMTS mobile termination supporting the GSM BSS and UTRAN radio interfaces - It shall be possible for the standardised classes of UMTS mobile termination supporting the GSM BSS and UTRAN radio interfaces to roam in GSM networks and receive GSM services. x.5 MMI-Aspects The manual procedure of network selection will require some user interaction. x.6 Charging Aspects None identified. x.7 Security Aspects None identified. x.8 Impacts Affects: USIM ME NW Others Yes X X x No Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release 1999.

12 x MAP over TCP/UDP/IP x.1 SMG project UMTS Radio Access GSM Radio Access XGSM-UMTS Core Network UMTS Services x.2 Linked work items None identified x.3 Justification It has been identified that the UMTS core network will evolve from the GSM core network. In particular, the HLR will evolve into a Service Provider controlled database. It is not seriously doubted that the protocol used to communicate between an HLR and network subsystem nodes, e.g. the SGSN, will be an evolution of MAP (GSM 09.02). At this point, it is hard to say anything, with any level of certainty, regarding the detail of the functions that will enhance an HLR. What can be said with certainty is that: the volume of the information to be transferred between an HLR and a network subsystem node will increase substantially. Already, subscription data volumes exceed that of the SCCP UNITDATA service and inelegant solutions have been improvised at the MAP level. This ad hoc mechanism should not be continued. The correct solution is to find a suitable transport mechanism; the underlying transport mechanism used by MAP should not assume a homogenous world. Diversity of networking technology throughout the world, reuse of existing networking investments, must all be recognized and taken into account; and the underlying transport mechanism used to deliver MAP PDUs must be much more flexible than the current SS7 stack (TCAP/SCCP/MTP). In cannot be assumed in UMTS that Service Providers will have access to an SS7 entry point; in fact, the reverse must be assumed. The physical-level capabilities of SS7 are limited by ISDN s trunking structure; these are much too restrictive for UMTS and should not be built upon. In the last bullet point, flexible means that the underlying transport mechanism used to transfer MAP PDUs should satisfy the following requirements: connection-oriented/connectionless transport services should be supported; low to very high bandwidth communications should be possible (from 64kbps to Xmbps); the transport service should not assume a lower layer architecture-it should be operable over X.25, Frame Relay, ATM, WAN/LAN and other networking technologies local to different parts of the world. It should separate MAP from the underlying network structures; the transport service should be deployable within Service Provider premises (who will certainly not all be SS7 trusted partners); and the transport service should not be reinvented, but should be an off the shelf solution which is widely available. While an exhaustive, i.e. time consuming, academic study could be made of various solutions that meet these requirements, Motorola believes that this will only delay UMTS and yield little information that is not already widely known throughout the industry. The obvious solution seems clear: carry MAP over TCP/UDP/IP. x.4 Service Aspects The work item will upgrade MAP s transport service, allowing new Service Provider s to easily access the UMTS market. It will also free MAP from the limitations imposed upon it by SS7, giving MAP the ability to expand more freely. x.5 MMI-Aspects None identified x.6 Charging Aspects FFS

14 x Virtual Home Environment x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network x UMTS Services x.2 Linked work items Service Management, CAMEL phase 3, MExE, SIM Toolkit x.3 Justification UMTS TS «Services and Service Capabilities» identifies the service capabilities provided by UMTS which allow the creation of new and innovative applications. These building blocks are the teleservices, the bearer services and the service features. Service features are toolkits which allow service providers to create and provide new services on any UMTS network and any UMTS mobile station, subject to the limitations of the UMTS network and mobile station. The concept of providing the same services in the same way whatever UMTS network and UMTS mobile station is called Virtual Home Environment. This work item addresses the control aspects of VHE. Service management aspects of VHE are covered in a separate work item. This work item is a phase 1 work item. x.4 Service Aspects The technologies which could be used to provide Virtual Home Environment are CAMEL phase 3, MExE and the SIM Toolkit. x.5 MMI-Aspects None. x.6 Charging Aspects None identified. x.7 Security Aspects None. x.8 Impacts Affects: USIM ME NW Others Yes X x x No Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release x.10 Work item rapporteurs Erwin Postmann x.11 Supporting companies Motorola, FT, Ericsson, MMO, Siemens, T-Mobil, Fujitsu, Lucent. x.12 Responsible STC(s)

16 x Service Management x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network x UMTS Services x.2 Linked work items Virtual Home Environment x.3 Justification UMTS TS «Service Principles» has created the concept of the Virtual Home Environment, which is addressed in a separate work item. However, Service Providers will require a set of tools to manage the VHE which are collectively covered by the term Service Management. This will involve the creation, deployment, provisioning and removal of services on a per-user basis. It will also require the service provider to be able to determine within UMTS serving network if specific services cannot be offered due to lack of supporting features or temporarily unavailability. One important requirement for the service management is the provision of a consistent service platform which integrates harmoniously the different VHE technologies. A work item is therefore required to address these requirements, and develop a solution for Service Management covering these aspects. This work item is a phase 1 work item. x.4 Service Aspects The service requirements are covered in TS «UMTS Service Management». x.5 MMI-Aspects None. x.6 Charging Aspects None identified. x.7 Security Aspects None. x.8 Impacts Affects: USIM ME NW Others Yes X x x No Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release x.10 Work item rapporteurs x.11 Supporting companies Motorola, FT, Ericsson, MMO, Siemens, T-Mobil, Fujitsu, Lucent. x.12 Responsible STC(s) Prime : SMG6

18 x UMTS Access Security x.1 SMG project UMTS Radio Access GSM Radio Access xgsm-umts Core Network UMTS Services x.2 Linked work items x.3 Justification UMTS introduces security requirements for access to UMTS networks. Interoperability issues (access to UMTS networks with GSM access modules and access to GSM networks with UMTS access modules) are also seen as essential. A work item is required to develop a security model with appropriate signalling interfaces between the components. This work item is a UMTS phase 1 work item. x.4 Service Aspects The USIM requirements for UMTS phase 1 are the following : 1. USIM shall provide new and enhanced security features (e.g. mutual authentication...) as defined by SMG It shall be possible to use the USIM as an access module in a GSM network (with a security level of GSM) for the standardised classes of UMTS mobile terminals supporting the GSM BSS and UTRAN radio interfaces. It is not required to support USIM in existing GSM terminals. 3. The UMTS mobile terminal shall support phase 2 and phase 2+ GSM SIMs as access modules to UMTS networks. The services that can be provided in this case may be limited to GSM like services provided within that UMTS network. UMTS mobile terminals do not have to support 5V SIMs.It shall be up to the UMTS network operator whether or not to accept the use of GSM SIM as access modules in its network. 4. It shall be possible to have multiple applications on the UMTS IC card (UICC). There shall be a secure and easy mechanism for application selection. An unauthorised access between applications shall not be possible, however it shall be possible to have shared directories between applications when appropriate. UICC shall be capable of supporting SIM and USIM applications. 5. Simultaneous activation of several USIMs on one mobile terminal is not required for UMTS phase A standardised mechanism allowing highly secure transfer of applications and/or associated data to/from the UICC shall be supported in UMTS phase 1. x.5 MMI-Aspects None identified. x.6 Charging Aspects None identified. x.7 Security Aspects This work item is primarily addressing security issues. x.8 Impacts -- best possible information requested Affects: USIM ME NW Others Yes x x x No Don't know x.9 Expected Output and Timescales (to be updated at each plenary)

20 x x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network X UMTS Services Work Item Description UMTS Numbering, Addressing and Identities x.2 Linked work items VHE x.3 Justification UMTS is a telecommunications system which allows person to person and machine to machine interactions. Addressing schemes allow users (people or machines) to indicate to the system the target of a particular communications session. Traditionally, this has involved a user dialling a telephone number to indicate the destination of a telephone call. This WI shall elaborate the desirable features of the UMTS advanced schemes requirements for numbering, addressing and Identities for UMTS and translation mechanisms which could be used to enhance the service to the customer. The requirements developed in this WI are to be used within ETSI NA2 to develop a proposal for numbering, addressing and identities applying existing schemes or developing new ones. Other ETSI groups will be involved in the development of addressing of applications and network elements. This work item is a phase 1 work item. x.4 Service Aspects In addition to present numbering schemes, connection set up may be based on an alpha-numeric basis, either in place of a traditional number or in the style of the Internet. This may also be extended so as not to exclude other approaches, based on database checking, and also for terminal as well as user/subscriber numbering. This Work item is applicable to both GSM and UMTS. The need for UMTS users to be able to interwork with users on legacy schemes. These would encompass telephony, data and multimedia. Unique identification of various entities in an UMTS environment is required. For UMTS phase 1 the requirements are the following : The phase 1 UMTS core network shall support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes (E.164, X.121, IP v4/6). Different UMTS internal identities (e.g. location areas, cell IDs) have to be considered x.5 MMI-Aspects Numbering is an MMI topic. x.6 Charging Aspects Is charging still based on the dialled number? x.7 Security Aspects None identified.

22 x UMTS Charging and Billing x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network X UMTS Services x.2 Linked work items None identified x.3 Justification UMTS Charging and Billing requirements cover a range of voice and data services which are not yet available in GSM. Whilst GPRS billing features will cover many aspects of packet data, it does not yet address the QoS aspects required for multimedia and other packet-data oriented services. There is also a requirement for online billing and for external 3 rd parties (Value Added Service Providers) to be able to offer services and receive payment. These requirements are covered in SMG1 Service Requirement specification A work item is therefore required to address these requirements, and develop a solution for UMTS Charging and Billing. This work item is a phase 1 work item. x.4 Service Aspects The UMTS phase 1 requirements are the following : 1. The phase 1 UMTS core network shall support the generation of standardised charging records based among other parameters on duration, traffic (volume, bit rate) and performance provided to the user. 2. The phase 1 UMTS core network shall support on-line billing. Billing of 3 rd party value added services with the concept of one-stop-billing shall be supported by the phase 1 UMTS core network through standardised procedures. x.5 MMI-Aspects None. x.6 Charging Aspects This work item addresses all charging aspects of UMTS. x.7 Security Aspects None. x.8 Impacts Affects: USIM ME NW Others Yes X x x No Don't know x.9 Expected Output and Timescales (to be updated at each plenary) This work item is for release x.10 Work item rapporteurs David Chambers. x.11 Supporting companies Motorola, FT, Ericsson, MMO, Siemens, T-Mobil, Fujitsu, Lucent.

24 x QoS Support in GPRS for UMTS phase 1 x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network X UMTS Services x.2 Linked work items Teleservice and Bearer Service Negotiation. UTRA and GSM BSS relationship. Enhanced QoS support in GPRS. x.3 Justification It has been identified that the phase 1 UMTS core network will be an evolution of the GSM core network. Furthermore, it will be possible to integrate GSM access networks in a UMTS network to guarantee service continuity. It is foreseen that UMTS will provide a transport platform for diverse application types including real time and interactive applications. The GSM BSS access network and the GPRS backbone provide an infrastructure that can be evolved to meet UMTS requirements. However, in addition to the bearer service classes supported by the GPRS platform today, it must support real time and interactive applications. This is the purpose of this work item. This work item is a phase 1 work item. x.4 Service Aspects The requirements for the GPRS part of the GSM BSS access network are the following : The GSM BSS (GPRS part) shall allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics. The re-negotiation may result from an upper layer request or a change in the radio conditions (handover, cell load modification,...). It shall be possible to apply connection admission control during connection set-up and re-negotiation. It shall be possible to apply flow control on a connection during its lifetime. It shall be possible to apply usage parameter control on a connection during its lifetime. The GSM BSS (GPRS part) shall allow to request a range of traffic and performance characteristics for the connectionless traffic. The GSM BSS (GPRS part) shall allow one mobile termination to have more than one connection mode (connection oriented and connectionless trafic) and/or more than one connection simultaneously. It shall be possible for each connection to have independent traffic and performance characteristics. It shall be possible for each connectionless message to have independent traffic and performance characteristics. The requirements for the GPRS backbone are the following : 1. Support packet switched data services of at least 2 Mbit/s peak bit rate. 2. Allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics. It shall be possible to apply traffic policy (e.g. connection admission control, flow control, usage parameter control...) on a connection during its set-up and lifetime. 3. Support a range of traffic and performance characteristics for the connectionless traffic. 4. Allow one mobile termination to have more than one connection mode (connection oriented and connectionless trafic) and/or more than one connection simultaneously. It shall be possible for each connection to have independent traffic and performance characteristics. It shall be possible for each connectionless message to have independent traffic and performance characteristics. 5. In order to facilitate the development of new applications, it shall be possible to address applications to/from a mobile termination in connection oriented and connectionless traffic modes (notion of port). x.5 MMI-Aspects None identified.
