Foreword This Technical Speci
14、fication (TS) has been produced by ETSI Project Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON). Introduction The present document contains proposals for extensions and additions to the TIPHON Release 3 and Release 4 deliverable on the protocol framework definition (TS
15、101 882 1). TIPHON and UMTS developments do not share a common method to achieve a common goal. However the core methods proposed by TIPHON in TS 101 878 2 of service capabilities as service independent building blocks allows the services defined in UMTS by the 3rdGeneration Partnership Project (3GP
16、P) to be synthesized. Examples of the synthesis of some example UMTS services are given in TS 102 289 3. The initial report on the harmonization (TS 102 285 4) did however identify some capabilities that may be required to be standardized in the TIPHON suite to ensure that all UMTS services can be s
17、ynthesized. These missing capabilities are identified in TS 102 283 5. ETSI ETSI TS 102 286 V1.1.1 (2003-11) 5 1 Scope The present document defines extensions to the TIPHON meta-protocol suite of service capabilities to enable full harmonization with the UMTS services identified in 3GPP TR 24.841 9.

34、on and service attachment service according to ITU-T Recommendation I.130 7. The meta-protocol in TS 101 882-2 6 identifies 4 Functional Entities (FEs) and a mapping of these FEs to domains in a number of scenarios. The overall meta-protocol for the registration and service attachment service was de
35、veloped to enable support of the mechanisms developed in 2ndgeneration mobile network devices (e.g. GSM, TETRA and DECT). There is no documented method of implementing the equivalent service using SIP in UMTS Release 6. It should be noted that the Radio Access Network of 3rdgeneration mobile systems
36、 has not abandoned the registration capabilities of 2ndgeneration systems and therefore the TIPHON meta-protocol, derived from 2ndgeneration systems, maintains support for 3rdgeneration systems. Furthermore services being introduced to UMTS based on SIP Instant Messaging concepts of a presence servi
37、ce also map to the capability set defined in TS 101 878 2. TS 101 884-1 8 describes a mapping of SIP to TS 101 882-2 6 that shows that the SIP registration service does not meet the TIPHON meta-protocol requirements completely. However in UMTS-Release 6 a SIP guide for implementing a presence servic
38、e (as for instant messaging) has been defined in 3GPP TR 24.841 9 that has similar capabilities to those defined in TS 101 878 2 but that does not fully map to the registration service as defined by TS 101 882-2 6. The full support of the PUBLISH message in SIP and the behaviour surrounding it will
39、require that this mapping and comparison of the capability of TIPHON and UMTS is revisited. 5 Simple call 5.1 Introduction TS 101 882-3 10 describes the information flows and behaviour of the simple call service according to ITU-T Recommendation I.130 7. The meta-protocol in TS 101 882-3 10 identifi
40、es 11 Functional Entities (FEs) and a mapping of these FEs to domains in a number of scenarios. The overall meta-protocol for the simple call service was developed to enable support of the ISDN and PSTN call services and those call services defined by ITU-T Recommendation H.323 11. There is no docum
41、ented method of implementing the equivalent service using SIP in UMTS Release 6, although a report on implementing multimedia call control using SIP is available as TS 124 228 16. TS 101 884-1 8 describes a mapping of SIP to TS 101 882-3 10 that shows that SIP does not meet the TIPHON meta-protocol
42、requirements completely. In some cases the data definitions in TIPHON are over restrictive for simple mapping to SIP. The following clauses identify where changes to the TIPHON specification in TS 101 882-3 10 should be modified to allow greater harmonization of UMTS and TIPHON. 5.2 Detailed mapping
43、 of TIPHON simple call parameters to UMTS SIP TIPHON parameters, in TS 101 882-3 10, are defined using ASN.1 and do not map directly to the definitions used in SIP or in SDP. 5.2.1 Call identifier The ASN.1 definition of Call identifier in TS 101 882-3 10 is: CallIDType := Natural The UMTS SIP equiv
44、alent is the combination of the Call-ID, To tag, and From tag. Although it would be possible to map between the two domains, the CallIDType in TIPHON may be defined differently to enable a more direct mapping whilst retaining support for mapping between TIPHON and other (not SIP based) protocols. ET
45、SI ETSI TS 102 286 V1.1.1 (2003-11) 8 5.2.2 Calling user ID and called user ID The ASN.1 definition of Calling user ID and Called user ID in TS 101 882-3 10 is: TiphonUserName := CHOICE e164 E164Number, url Visiblestring, displayName Visiblestring The UMTS SIP equivalent is the From header field, th
46、at contains a URI and an optional display name. The current meta protocol type definition allows the SIP calling user information to be mapped, however a more direct mapping is possible if the meta-protocol definition for calling and called user ID is modified. The TiphonUserName definition should b
47、e modified to a SEQUENCE type with an optional element for displayName as shown below: TiphonUserName := SEQUENCE primaryName CHOICEe164 E164Number, url Visiblestring, displayName Visiblestring OPTIONAL 5.2.3 Calling user ID restriction The ASN.1 definition of Calling user ID restriction in TS 101 8
48、82-3 10 is: IdentityRestrictionType := ENUMERATED identityAvailable, identityUnavailable The UMTS SIP/SDP equivalent is the From header field. If in a session initiation a user wants to restrict the identity the string “Anonymous“ is assigned to the From header field, clause 5.1.2A.1, TS 124 229 12.
49、 5.2.4 Operator selection The ASN.1 definition of Operator selection in TS 101 882-3 10 is: OperatorSelection := CHOICE prefixdial SEQUENCE OF TelephoneDigitType, operatorID Visiblestring No equivalent capability is supported by the UMTS SIP/SDP protocol, TS 124 229 12. 5.2.5 Service offer ticket The ASN.1 definition of the Service Offer Ticket in TS 101 882-3 10 is: TicketType := SEQUENCE registrantId Visiblestring, registrarId
