ETSI ETSI TS 124 238 V13.0.0 (2016-01)53GPP TS 24.238 version 13.0.0 Release 131 Scope The present document provides a Session Initiation Protocol (SIP) based protoco
21、l framework that serves as a means of user configuration of supplementary services in the IP Multimedia (IM) Core Network (CN) subsystem. The protocol framework relies upon the contents of the Request-URI in a SIP INVITE request to enable basic configuration of services without requiring use of the
22、Ut interface. The present document is applicable to User Equipment (UE) and Application Servers (AS) which are intended to support user configuration of supplementary services. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the

For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP doc

The contents of the Request-URI in a SIP INVITE request is used to conve
30、y the configuration code to the Application Server that hosts the supplementary service. Upon session initiation, the contents of the Request-URI are delivered by means of normal session setup signalling, as described in 3GPP TS 24.229 3 to an Application Server. The Application Server then acts upo
31、n the Request-URI contents to effect the desired configuration data change (e.g., register and activate Communication Forwarding unconditional). Procedures regarding Operator Determined Barring (ODB) are defined in 3GPP TS 24.315 6. 4.2 Syntax requirements The precise digit sequences within the Requ
32、est-URI that comprise the effective dialstrings for user configuration are defined by the IM CN subsystem service provider and are not subject to standardisation. NOTE 1: The digit sequence corresponding to the feature code can begin with a special character such as “#“ or “*“ according to network o
33、perator preferences. The length of the digit sequence is also defined by the network operator. The digit sequences corresponding to the feature code shall be transported to the AS in the Request-URI of a SIP INVITE request as follows: 1) as a SIP URI dial string conforming to RFC 4967 4 where the “p
34、hone-context“ parameter is set to the home network domain name and the “user“ parameter is set to “dialstring“; 2) as a SIP URI that is not a GRUU, with the user part preceded with a “+“, the “user“ parameter set to “phone“ and the domain part set to the home network domain; or 3) as a tel URI with
35、a “phone-context“ parameter set to the home network domain as defined in RFC 3966 5. NOTE 2: The format for encoding of the digit sequence defined in the first bullet is the preferred format. The other two formats are now deprecated. 4.3 Signalling requirements 4.3.1 General Two roles are recognized
36、 for the implementation of SIP-based user configuration: 1) UE (SIP-based user configuration client); and 2) Application Server. 4.3.2 Actions at the originating UE (SIP-based user configuration client) When performing SIP-based user configuration, the UE shall create a SIP URI, as described in RFC
37、4967 4, with: ETSI ETSI TS 124 238 V13.0.0 (2016-01)73GPP TS 24.238 version 13.0.0 Release 13a) a dialstring, set to either the concatenation of feature code and the number to be provisioned or the feature code alone if no number information needs to be provided for the service; and b) a “phone-cont
38、ext“ parameter, set to the home network domain name. The UE shall construct and initiate an appropriate INVITE in accordance with 3GPP TS 24.229 3 with the Request-URI set to the URI created above. 4.3.3 Actions at the AS serving the originating UE Upon receiving an INVITE request with a Request-URI
39、 containing a URI configured as defined in bullet 1 of subclause 4.2, the AS shall perform service activation, deactivation, or configuration data modification based on the recognized contents of the Request-URI. An AS can receive an INVITE request with a Request-URI containing a URI configured as d
40、efined in bullets 2 and 3 of subclause 4.2. In which case, the AS may treat this Request-URI as a dial-string, as specified above. Based on the outcome of the service configuration operation, the AS may: - play an appropriate announcement using the methods specified in 3GPP TS 24.628 7 to notify the
41、 user of the result of the operation; or - send an appropriate error response in case the AS was unable to perform the requested service configuration operation.
