The present document defines the architectural description for emergency services in the IP Multimedia Core Network Subsystem

19、(IMS), including the elements necessary to support IP Multimedia (IM) emergency services The present document covers also the Access Network aspects that are crucial for the provisioning of IMS emergency services. 2 References The following documents contain provisions which, through reference in th

For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In

26、 123 509 V8.0.0 (2008-10) 6 3GPP TS 23.509 version 8.0.0 Release 8 Clause 4.1 Architectural Principles After item 7, add the following: NOTE: For NGN fixed access, the additional emergency registration is for further study. Clause 6.1 UE Add the following as the first paragraph of the section: The s

27、teps described below applies to UEs that are able to detect that a user is requesting an emergency session: In case the UE is not able to detect that the user is requesting an emergency session, the session establishment will from the UEs perspective proceed as the establishment of an ordinary multi

28、media session. Clause 6.2.1 Proxy-CSCF Delete the third bullet item “Reject/allow unmarked emergency requests“. Clause 7.1.1 UE Detectable Emergency Session After NOTE 2 that follows item 5 add the following: NOTE 2a: For NGN fixed access, the mechanisms and procedures for discovery of a local P-CSC

29、F that is suitable for use in emergency sessions, are for further study. Therefore, the ordinary procedures for P-CSCF discovery may be used. Clause 7.1.2 Non UE Detectable Emergency Session After the third bullet item starting Alternatively, the P-CSCF add the following: NOTE: For NGN fixed access,

30、 the third alternative is always to be used. ETSI ETSI TS 123 509 V8.0.0 (2008-10) 7 3GPP TS 23.509 version 8.0.0 Release 8 New Annex ZA (normative): Call back of Emergency Session At the end of the document add the following new annex: Annex ZA (normative): Call back of Emergency Session NOTE: The

31、PSAP can return a call to the UE, via the S-CSCF in the home network, using existing basic call procedures. Procedures for a real Emergency call back is a GAP for this release. Alternative methods and procedures for establishing an emergency call back session, e.g. via the E-CSCF in the local networ

32、k, is for further study ETSI ETSI TS 123 509 V8.0.0 (2008-10) 8 3GPP TS 23.509 version 8.0.0 Release 8 New Annex ZB (informative): Examples of Network Connection Model for Emergency services At the end of the document add the following new annex: Annex ZB (informative): Examples of Network Connectio

33、n Model for Emergency services This annex provides typical examples of network connection model to support emergency services. The annex clarifies the NGN Release 1 ability to support emergency services depending on the network connection model. It also clarifies which network is responsible for the

34、 connection to PSAP. Three connecting cases using the TISPAN NGN are described as follows. ZB.1 Non roaming PSAP S-CSCF E-CSCF UE P-CSCF Provider 1 RACS Ordinary Call Figure ZB.1 The Figure ZB.1 shows the case where the Provider 1 network handles both ordinary calls and emergency calls to be connect

35、ed to PSAP. Provider 1 takes the responsibility on the connection to PSAP. This is one of the network connection model case provided by TISPAN NGN Release1 Emergency services. ETSI ETSI TS 123 509 V8.0.0 (2008-10) 9 3GPP TS 23.509 version 8.0.0 Release 8 ZB.2 Roaming at IMS level PSAP E-CSCF UE Prov

36、ider 1 RACS Provider 2 P-CSCF S-CSCF Ordinary Call Figure ZB.2 Figure ZB.2 shows the case where Provider 1 network handles ordinary calls and the other Provider 2 network handles emergency calls to be connected to PSAP. The P-CSCF is located in Provider 2. Thus this is a case of IMS level roaming. P

37、rovider 2 Network takes the responsibility on the connection to PSAP. This is one of the network connection model case provided by TISPAN NGN Release1 Emergency services. ZB.3 Roaming at the Access Network level Provider 2 PSAP S-CSCF E-CSCF UE P-CSCF Ordinary Call Access Provider 1 Country A Countr

38、y B RACS P-CSCF Country B Provider Figure ZB.3 Figure ZB.3 shows the case where Provider 1 network handles ordinary calls using their own P-CSCF, and the other Provider 2 network handles emergency calls to be connected to PSAP using their own P-CSCF. P-CSCFs are located in both Provider 1 and 2 resp

39、ectively. This is a case of Access Network level roaming. Access Provider and Provider 2 jointly takes the responsibility on the connection to PSAP. In this case, it is necessary to clarify the mechanism on how UE selects the P-CSCF providing emergency services. As the current architecture of UE and

40、 the access network does not provide or handle any information on which P-CSCF has the ability to connect to PSAP for the serving user, enhancements in the UE and the access network is needed to support this case. Therefore, this network connection model case is out of scope of the TISPAN NGN Releas
