1 UMTS Phase 1 Specifications ETSI TC SMG #26 Plenary Tdoc SMG 327 / 98 Helsinki, Finland, June 22-25, 1998 Agenda Item: 7.3 ETSI SMG1 Ad-hoc on UMTS phase 1 Tdoc SMG1 Adhoc 037 / 98 Newbury, UK, June 2-3, 1998 Agenda item:3.1 Source: SMG1 Ad Hoc UMTS phase 1 capabilities This Tdoc shall be used to produce version of the new specification «UMTS phase 1 capabilities» for SMG# A phased approach for UMTS The UMTS system will be defined in a phased approach. This specification addresses the UMTS phase 1 capabilities. The UMTS phase 1 capabilities are those of GSM phase 2+ release 99 completed by UMTS specific requirements. These additional requirements for UMTS phase 1 are listed in this specification for the different elements of a high level functional architecture composed of a UMTS mobile station, a UMTS access network and a UMTS core network. The fundamental difference between GSM and UMTS phase 1 resides in the support of high bit rate bearer services with the notion of negotiated traffic and QoS characteristics. UMTS phase 1 shall in particular support bursty traffic in an efficient way. The UMTS mobile station is composed of a USIM and a UMTS mobile termination. The phase 1 USIM is developed on the basis of the phase 2+ release 99 SIM. When UMTS specific requirements do not appear, this means that the GSM phase 2+ release 99 specifications for the SIM already cover the UMTS phase 1 requirements. The UMTS mobile termination is the component of the UMTS Mobile Station which supports functions specific to the management of the radio interface (Um). No requirements address the mobile termination itself as it is seen as being partly an element of the UMTS access network and partly an element of the UMTS core network (it contains protocols which peer entities are ended either in the access or in the core). Regarding the phase 1 UMTS access network, only the UTRAN (including both WCDMA and TD- CDMA radio interfaces) is considered as being part of the UMTS access network. Other types of access networks are for further consideration. UTRAN is a new access network and as such all the UTRAN requirements are defined in this specification. This includes in particular the interoperability requirements put on the UTRAN and GSM BSS access networks to cater with UMTS networks operating the two types of access networks. The phase 1 UMTS core network is developed on the basis of the phase 2+ release 99 GSM core network (i.e. the GSM NSS and the GPRS backbone infrastructures). When UMTS specific requirements do not appear, this means that the GSM phase 2+ release 99 specifications for the core network already cover the UMTS phase 1 requirements. It shall be noted that the advanced bearer capabilities of the phase 1 UMTS access network will not be integrally supported by the phase 1 UMTS core network. This however guarantees the viability of the UMTS access network as it is designed since phase 1 with the objective of supporting broadband bearer services. 1 / 12

2 UMTS Phase 1 Specifications The time plan for UMTS phase 1 is a stable set of specifications for the end of This time plan is considered of primary importance. If the required functionality is considered not feasible to finalise for the end of 1999, this shall be reported back to SMG1 for a possible redefinition of the contents. After phase 1, the new capabilities of UMTS shall be defined in annual releases (each release constituting a coherent set of UMTS mobile station, access network and core network specifications). UMTS phase 2 will be based on annual releases 2000, 2001 and 2002, allowing complete operational functionality by 2005 but partial operation in earlier stages. One fundamental objective of UMTS phase 2 to be taken into account since UMTS phase 1 design is that one possible implementation of the UMTS phase 2 core network shall be an integrated infrastructure, and not any more the juxtaposition of the GSM NSS and GPRS backbone. NOTE 1 : This specification describes UMTS phase 1 capabilities from a service point of view. As such, the terms connection oriented and connectionless always refer to the connection mode required by applications. It has nothing to do with the nature of the technology used to provide bearer services inside the network. NOTE 2 : The term GSM BSS refers in this specification to the GSM/GPRS access network. NOTE 3 : The term GSM core network refers in this specification to the GSM NSS and GPRS backbone infrastructures. NOTE 4 : The term UMTS network refers in this specification to a network operated by a single network operator and composed of : UTRAN access networks (WCDMA and/or TD-CDMA), optionally GSM BSS access networks, a UMTS core network. 2. UTRAN capabilities NOTE : The term performance refers in this section to the realisation of the QoS objectives inside the UTRAN. UTRAN capabilities for UMTS are the complete set of bearer capabilities and bearer control specified in TS The UTRAN shall have the following capabilities : 1. It shall be possible to connect one UTRAN to one and only one UMTS core network. (In the case of a phase 1 UMTS core network consisting of both a GSM NSS and a GPRS backbone, its 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 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). 2 / 12

3 UMTS Phase 1 Specifications 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 one mobile termination connection oriented and connectionless traffic 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. 7. At least one class of mobile termination supporting both WCDMA and TD-CDMA radio interfaces shall be standardised. 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. 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 the location of a UMTS mobile termination. It shall be possible for the location precision to be an UMTS network operator choice, with the precision of the location varying from one part of the service area to another. A minimum precision of around 50 meters shall be achieved in all types of terrestrial radio environments. Location requirements are detailed in TS section The optimisation of the UTRAN radio interface shall be done around the objectives expressed in TS section The USIM requirements defined for later releases of UMTS shall be taken into account in the design of UTRAN (if having any impact). 3. UTRAN and GSM BSS relationship There is a special relationship between the UTRAN and GSM access networks as it is expected that UTRANs will start as islands in a sea of GSM BSS. GSM BSS access networks will be a key element for service continuity in UMTS networks. The requirements are the following for UMTS phase 1 : 1. At least one class of mobile termination supporting the GSM BSS and UTRAN radio interfaces shall be standardised. 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). 3 / 12

4 UMTS Phase 1 Specifications 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, GSM BSS and UTRAN cells or UTRAN cells. 3. For UMTS networks composed of both GSM BSS and UTRAN access networks, the handover procedures in the UTRAN and the GSM BSS shall support handover 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 liberated 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). 4. UMTS Core Network NOTE : The term performance refers in this section to the realisation of the QoS objectives inside the UMTS core network. In the first phase of UMTS, the UMTS core network shall be developed on the basis of the phase 2+ release 99 GSM core network. The additional requirements for the phase 1 UMTS core network are as follows : 1. The phase 1 UMTS core network shall support up to 64 kbit/s circuit switched bearer services. 2. The phase 1 UMTS core network shall support packet switched data services of at least 2 Mbit/s peak bit rate. 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. 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 in line with 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. GPRS phase 2+ release 99 point to multipoint communication configurations 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. 4 / 12

5 UMTS Phase 1 Specifications 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 (notion of port). 9. Calls with multiple connections are not supported by phase 1 UMTS core networks. 10. Operator specific services based on the VHE concept defined in TS shall be provided by the phase 1 UMTS core network. This functionality could be provided through available toolkits (CAMEL, MExE and SIM Toolkit). 11. The phase 1 UMTS core network shall support the generation of call data records based on the traffic (volume, bit rate) and performance provided to the user. 12. 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. 13. The phase 1 UMTS core network shall support both bilateral and automatic roaming agreements between UMTS networks with improved security as defined by SMG The phase 1 UMTS core network shall support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes. TR addresses this issue in more details. 15. It shall be possible for the standardised classes of phase 1 UMTS mobile termination supporting the GSM BSS and UTRAN radio interfaces to roam in GSM networks and receive GSM services. 16. It shall be up to the UMTS network operator whether or not to accept the use of phase 1, phase 2 and phase 2+ SIM applications as access modules in their network. 17. The USIM requirements defined for later releases of UMTS shall be taken into account in the design of the phase 1 UMTS core network. 5. USIM In the first phase of UMTS, the USIM shall be developed on the basis of the phase 2+ release 99 GSM SIM. The additional requirements for the phase 1 UMTS USIM are as follows : 1. USIM is the GSM phase 2+ release 99 SIM for UMTS phase 1. It may provide new 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 termination supporting the GSM BSS and UTRAN radio interfaces. It is not required to support USIM in existing GSM terminals. 3. The UMTS mobile termination shall support phase 1, phase 2 and phase 2+ SIM applications as access modules. (It shall be up to the UMTS network operator whether or not to accept the use of these access modules in its network.) 4. Multiple USIM per smart card and simultaneous activation of several USIMs on one mobile termination are not required for UMTS phase 1. 5 / 12

6 UMTS Phase 1 Specifications 5. Multiple user profile per smart card shall be supported as specified in GSM phase 2+ Multiple Subscriber Profile work item. 6. Simultaneous activation of one user profile on different terminals through multiple USIMs is not required for UMTS phase 1. 6 / 12

7 UMTS Phase 1 Specifications 1. Definition of bearer services Annex 1 UMTS Bearer Services Bearer services provide the capability for information transfer between access points and involve only low layer functions. These functions are sometimes referred as low layer capabilities (in reference to OSI layers). On the top the application may choose any set of high layer protocols for which the UMTS network does not ascertain compatibility. 2. Bearer service control The two main categories of bearer services are the connection oriented bearer services and connectionless bearer services. The bearer service control capabilities depends on the category of bearer service. It shall be possible to negotiate the traffic and QoS characteristics of a connection oriented bearer service during its establishment. It shall be possible to re-negotiate the traffic and QoS characteristics of a connection oriented bearer service during its lifetime. It shall be possible to add and drop parties to/from a connection oriented bearer service during its lifetime, i.e. to change the communication configuration. It shall be possible for the network to apply connection admission control on a connection oriented bearer service during its establishment. Connection admission control is a network procedure used to limit admission of new connection oriented bearer services to those which do not compromise the traffic and QoS characteristics of the already established connection oriented bearer services. It shall be possible for the network to apply flow control on a connection oriented bearer service during its lifetime. Flow control is a network procedure used to regulate the traffic of a user. This is particularly important for Available Bit Rate and Unspecified Bit Rate traffic types. It shall be possible for the network to apply usage parameter control on a connection oriented bearer service 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. Connectionless bearer services lifetime is reduced to the transport of one message. It shall be possible to require traffic and QoS characteristics for a connectionless bearer service. In order to facilitate the development of new applications, it shall be possible to address applications in connections and connectionless messages (notion of port). It shall be possible for one mobile termination to have more than one bearer service simultaneously (one or more connection oriented bearer services and/or one or more connectionless bearer services). 3. Characterisation of bearer services Bearer services are characterised from a static point of view by a set of low layer attributes. This set has been chosen so that a bearer service can be entirely defined by assigning values to the attributes of the set. All the attributes and their possible values are listed in this section. Additional attributes may be specified in latter releases. The parameters of the set are grouped into two categories; - Information transfer attributes, which characterise the network transfer capabilities required for transferring user information between two or more access points. 7 / 12

8 UMTS Phase 1 Specifications - Information quality attributes, which characterise the quality of the user information transferred between two or more access points. Giving one of the possible values to each attribute defines a candidate bearer service. However, any combination is neither meaningful nor necessarily supported by the UMTS system. The meaningful and supported combinations are specified in the following section. Information transfer attributes (i) connection mode attribute connection oriented connectionless (ii) traffic type attribute constant bit rate Used for sources that require a static amount of bandwidth allocation in the network during the connection lifetime. The source is characterised by the Peak Bit Rate information transfer rate attribute. The source may emit at or below the Peak Bit Rate at any time and for any duration. The source keeps the control of the bit rate emission. variable bit rate Used for sources that require a dynamic amount of bandwidth allocation in the network during the connection lifetime. The source is characterised by the Peak Bit Rate and Minimum Bit Rate information transfer rate attributes, and whenever possible by the Mean Bit Rate information transfer rate attribute. The source keeps the control of the bit rate emission. available bit rate Used for sources that require a dynamic amount of bandwidth allocation in the network during the connection lifetime and have the ability to reduce or increase their information rate if the network requires them to do so. The source is characterised by the Peak Bit Rate and Minimum Bit Rate information transfer rate attributes. The network controls the source rate through flow control mechanisms. The bandwidth available from the network may vary but shall not become less than the Minimum Bit Rate. unspecified bit rate Used for sources that do not require any specific amount of bandwidth allocation in the network during the connection lifetime. The source is not characterised by any information transfer rate attribute. This is a best effort service. (iii) timing end to end attribute required not required The value required applies when a timing relationship is required between source and sink(s) of information. End to end timing is necessary for real time information. (iv) information transfer rate attribute (iv-1) peak bit rate (sub)attribute (iv-2) mean bit rate (sub)attribute (iv-3) minimum bit rate (sub)attribute 8 / 12

9 UMTS Phase 1 Specifications The Peak Bit Rate is defined as the maximum bit rate a source transmits data. The Mean Bit Rate is defined as the average bit rate a source would transmit data if it had an infinite activity. The Minimum Bit Rate is defined as the minimum bit rate a source transmits data. The possible values for these three (sub)attributes are not a limited set, but a continuous range of values. (v) symmetry attribute unidirectional (together with the direction of transmission) bi-directional symmetric bi-directional asymmetric The value unidirectional applies when the information flow is provided only in one direction. The value bi-directional symmetric applies when the information flow characteristics are the same in the two directions. The value bi-directional asymmetric applies when the information flow characteristics are different in the two directions. (vi) communication configuration attribute point to point point to multipoint - multicast point to multipoint - broadcast The value point to point applies when the communication is from a single point to another single point. The value point to multipoint - multicast applies when the communication is from a single point to a limited number of specified destinations. The value point to multipoint - broadcast applies when the communication is from a single point to an unlimited number of unspecified destinations. (vii) structure attribute message flow The value message applies when the information (the Service Data Units or SDUs) provided by a source shall be delivered with the same structure to the sink(s) (the SDUs borders are unchanged by the network). Information quality attributes (i) maximum transfer delay attribute This is the maximum end to end transfer delay required by a source of information. The possible values for this attribute are not a limited set, but a continuous range of values. (ii) delay variation attribute This is the maximum end to end transfer delay variation required by a source of information. The possible values for this attribute are not a limited set, but a continuous range of values. (iii) bit error rate attribute This is the maximum bit error rate required by a source of information. The possible values for this attribute are not a limited set, but a continuous range of values. 9 / 12

10 UMTS Phase 1 Specifications 4. Supported combinations (i) Attributes not applicable to the connection oriented bearer services Some of the attributes used to characterise bearer services are not applicable to the connection oriented traffic. Applicability of the information transfer rate (sub)attributes Peak Bit Rate, Mean Bit Rate and Minimum Bit Rate depends on the value of the traffic type attribute, as indicated in the description of the traffic type attribute. (ii) Attributes not applicable to the connectionless bearer services Some of the attributes used to characterise bearer services are not applicable to the connectionless traffic. Those are the : traffic type timing end to end information transfer rate symmetry delay variation error characteristic Furthermore, the only authorised value of the structure attribute for the connectionless traffic is message. (iii) Supported topologies The supported combinations between the symmetry and communication configuration attributes are limited to the following topologies : point to point unidirectional point to point bi-directional symmetric point to point bi-directional asymmetric unidirectional point to multipoint - multicast unidirectional point to multipoint - broadcast (iv) Asymmetric bearer services In the case of bi-directional asymmetric (connection oriented) bearer services, the following attributes shall be defined for each direction of the connection : traffic type timing end to end information transfer rate structure maximum transfer delay delay variation bit error rate error characteristic It shall be possible for the two directions of the bi-directional asymmetric connection to have totally independent values for these attributes. 10 / 12

11 UMTS Phase 1 Specifications (iv) Mobile termination with more than one bearer service simultaneously In the case of a mobile termination with more than one bearer service simultaneously, it shall be possible for each bearer service to have totally independent values for the attributes. (iv) Supported information transfer rates The only limiting factor for the supported bit rates of connection oriented and connection less bearer services shall be the Peak Bit Rate. The minimum targets of Peak Bit Rate to be supported by UMTS are radio environment dependent : At least 144 kbits/s in satellite radio environment (Note 1). At least 144 kbits/s in rural outdoor radio environment. At least 384 kbits/s in urban/suburban outdoor radio environments. At least 2048 kbits/s in indoor/low range outdoor radio environment. NOTE 1 : This may only be achieved in a nomadic operating mode. (v) Supported information quality The following table indicates the range of values that shall be supported by UMTS for the information quality attributes. Timing end to end Required (Real Time) Timing end to end Not Required (Non Real Time) Operating BER/Max Transfer Delay environment Satellite Max Transfer Delay less than 400 ms (Terminal relative speed to BER ground up to (Note 1) 1000 km/h for plane) Rural outdoor Max Transfer Delay ms (Terminal relative speed to BER ground up to 500 (Note 1) km/h) (Note 3) Urban/ Suburban Max Transfer Delay ms outdoor (Terminal BER relative speed to (Note 1) ground up to 120 km/h) Indoor/ Low Max Transfer Delay ms range outdoor (Terminal BER relative speed to (Note 1) ground up to 10 km/h) BER/Max Transfer Delay Max Transfer Delay 1200 ms or more (Note 2) BER = 10-5 to 10-8 Max Transfer Delay 150 ms or more (Note 2) BER = 10-5 to 10-8 Max Transfer Delay 150 ms or more (Note 2) BER = 10-5 to 10-8 Max Transfer Delay 150 ms or more (Note 2) BER = 10-5 to 10-8 NOTE 1; There is likely to be a compromise between BER and delay. NOTE 2; The Max Transfer Delay should be here regarded as the target value for 95% of the data. NOTE 3; The value of 500 km/h as the maximum speed to be supported in the rural outdoor environment was selected in order to provide service on high speed vehicles (e.g. trains). This is not meant to be the typical value for this environment (250 km/h is more typical). 11 / 12

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 : 1. speech selection of speech codec or if not default codec selection of interworking to PSTN, ISDN, GSM, Internet 2. emergency calls 3. short message service 4. facsimile 5. internet access 6. Support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes. For bearer services : 1. Support up to 64 kbit/s circuit switched bearer services. 2. Support packet switched data services of at least 2 Mbit/s peak bit rate. 3. Allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics.

Support a range of traffic and performance characteristics for the connectionless traffic. 5. The range of traffic and performance characteristics that shall be supported for connection oriented and connectionless traffic shall be in line with GPRS phase 2+ release GPRS phase 2+ release 99 point to multipoint communication configurations shall be supported. 7. 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. 8. In order to facilitate the development of new applications, it shall be possible to address applications to/from a UMTS mobile termination in connection oriented and connectionless traffic modes (notion of port). 9. Calls with multiple connections are not supported. 10. Support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes. 3 / 24

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. It shall be possible to connect one UTRAN to one and only one UMTS core network. (In the case of a phase 1 UMTS core network consisting of both a GSM NSS and a GPRS backbone, its 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 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 TS section 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 one mobile termination connection oriented and connectionless traffic 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. 7. At least one class of mobile termination supporting both WCDMA and TD-CDMA radio interfaces shall be standardised. 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. 5 / 24

18 UMTS Phase 1 Work Items 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 the location of a UMTS mobile termination. It shall be possible for the location precision to be an UMTS network operator choice, with the precision of the location varying from one part of the service area to another. A minimum precision of around 50 meters shall be achieved in all types of terrestrial radio environments. Location requirements are detailed in TS section The optimisation of the UTRAN radio interface shall be done around the objectives expressed in TS section The USIM requirements defined for later releases of UMTS shall 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 6 / 24

19 x UTRAN and GSM BSS Relationship UMTS Phase 1 Work Items 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 of mobile termination supporting the GSM BSS and UTRAN radio interfaces shall be standardised. 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, GSM BSS and UTRAN cells or UTRAN cells. 3. For UMTS networks composed of both GSM BSS and UTRAN access networks, the handover procedures in the UTRAN and the GSM BSS shall support handover 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 liberated 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) 7 / 24

23 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 UMTS Phase 1 Work Items 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 11 / 24

25 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 Phase 1 Work Items 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) 13 / 24
