ETSI ETSI TS 124 238 V14.0.0 (2017-03)53GPP TS 24.238 version 14.0.0 Release 141 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 Multimedi

22、a (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 Ut interface. The present document is applicable to User Equipment (UE) and Application Servers (AS) w

23、hich 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 present document. - References are either specific (identified by date of publication, edition number

An abbreviation defined 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 protoco

30、l framework serves as a means of user configuration of supplementary services in the IM CN subsystem specified 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 se

31、ssion 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 upon the Request-URI contents to effect the desired configuration data change (e.g., register and a

32、ctivate 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 Request-URI that comprise the effective dialstrings for user configuration are defined by the IM CN

33、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 operator preferences. The length of the digit sequence is also defined by the network operator. T

34、he 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 “phone-context“ parameter is set to the home network domain name and the “user“ parameter is set t

35、o “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 a “phone-context“ parameter set to the home network domain as defined in RFC 3966 5. NOTE 2: The

36、 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 for the implementation of SIP-based user configuration: 1) UE (SIP-based user configuration cli

37、ent); 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 4967 4, with: ETSI ETSI TS 124 238 V14.0.0 (2017-03)73GPP TS 24.238 version 14.0.0 Release 14a)

38、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-context“ parameter, set to the home network domain name. The UE shall construct and initiate an appr

39、opriate 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 containing a URI configured as defined in bullet 1 of subclause 4.2, the AS shall perform servi

40、ce 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 defined in bullets 2 and 3 of subclause 4.2. In which case, the AS may treat this Request-URI as

41、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 user of the result of the operation; or - send an appropriate error response in case the AS was

42、 unable to perform the requested service configuration operation. 4.3.4 Password option 4.3.4.1 General By using 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 se

43、t to “by the service provider“ or “by subscriber using a password“. 4.3.4.2 Procedures at the UE When the subscription 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 includ

44、ing either a password with a feature code or both the current password and a new password to be 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, a

45、nd the subscription option “control of supplementary service“ is set to “by the service provider“, 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 operatio

46、n is rejected. When the subscription option “control of supplementary service“ is set to “by subscriber 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

47、 for verifying the current password stored against the user: - when the user requests a password change; and ETSI ETSI TS 124 238 V14.0.0 (2017-03)83GPP TS 24.238 version 14.0.0 Release 14- when the user requests modification of a supplementary service configuration document for a service that has p

48、assword 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. If the AS receives a password that does not

49、 match the current password stored for the service, the AS shall increment the WPA counter by 1. If a password check passes at the AS, the AS shall reset the WPA counter to zero. If the WPA counter exceeds the value three, the AS shall set the subscription option “control of supplementary service“ to “by the service provider“. 4.3.4.3.2 Password check If the subscription option “control of supplementary service“ is set to “by subscriber using a password“ for a supplementary service configuration and a password change request is received
