23、 151 Scope The present document provides a Session Initiation Protocol (SIP) based protocol 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
24、SIP INVITE request to enable basic configuration of services without requiring use of the 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 docume
25、nts contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - Fo
26、r a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Spec

An abbreviation defi
31、ned in the present document takes precedence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 1. 4 SIP based user configuration 4.1 General description SIP-based protocol framework serves as a means of user configuration of supplementary services in the IM CN subsystem specifi
32、ed in 3GPP TS 24.173 2. The contents of the Request-URI in a SIP INVITE request is used to convey 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,
33、 as described in 3GPP TS 24.229 3 to an Application Server. The Application Server then acts upon 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
34、defined in 3GPP TS 24.315 6. 4.2 Syntax requirements The precise digit sequences within the Request-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
35、to the feature code can begin with a special character such as “#“ or “*“ according to network operator 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
36、SIP INVITE request as follows: 1) as a SIP URI dial string conforming to RFC 4967 4 where the “phone-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“ param
37、eter set to “phone“ and the domain part set to the home network domain; or 3) as a tel URI with 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 tw
38、o formats are now deprecated. 4.3 Signalling requirements 4.3.1 General Two roles are recognized 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) W
39、hen performing SIP-based user configuration, the UE shall create a SIP URI, as described in RFC 4967 4, with: a) 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
40、 b) a “phone-context“ parameter, set to the home network domain name. ETSI ETSI TS 124 238 V15.0.0 (2018-06)73GPP TS 24.238 version 15.0.0 Release 15The 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
41、Actions at the AS serving the originating UE Upon receiving an INVITE request with a Request-URI 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 Requ
42、est-URI. An AS can receive an INVITE request with a Request-URI containing a URI configured as defined 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:
43、- play an appropriate announcement using the methods specified in 3GPP TS 24.628 7 to notify the 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. 4.3.4 Password option 4.3.4.1 General By u
44、sing the subscription option “control of supplementary service“, the service configuration may be restricted by a password. The subscription option “control of supplementary service“ can be set to “by the service provider“ or “by subscriber using a password“. 4.3.4.2 Procedures at the UE When the su
45、bscription option “control of supplementary service“ is set to “by subscriber using a password“, the UE shall create the INVITE request as described in subclause 4.3.2 with a dialstring including a feature code with either the current password or both the current password and the new password to be
46、registered. 4.3.4.3 Procedures at the AS 4.3.4.3.1 General When the AS receives a Request URI in the INVITE request as defined in subclause 4.2 with a service configuration or a password change request, and the subscription option “control of supplementary service“ is set to “by the service provider
47、“, the AS shall send a 403 (Forbidden) error response. As a network option, the AS may play an appropriate announcement using the methods specified in 3GPP TS 24.628 7 to notify the user that the operation is rejected. When the subscription option “control of supplementary service“ is set to “by sub
48、scriber using a password“, the AS shall perform the password management procedures that consist of two independent procedures: - password check; and - password change; The password check procedure is used for verifying the current password stored against the user: - when the user requests a password
49、 change; and - when the user requests modification of a supplementary service configuration document for a service that has password control. The password change procedure is used by the AS to set a new password for the user. The AS shall maintain a Wrong Password Attempts (WPA) counter. When the password is set by the service provider the AS shall reset the WPA counter to zero. ETSI ETSI TS 124 238 V15.0.0 (2018-06)83GPP TS 24.238 version 15.0.0 Release 15If the AS receives a password that does not match the current password stored for
