Method and apparatus for controlling services in an internet protocol multimedia subsystem
Abstract:
A method for controlling services in an Internet Protocol Multimedia Subsystem, IMS, the IMS comprising a Home Subscriber Server, HSS, and a Serving Call Session Control Function server, S-CSCF. The method comprises: configuring (4110) in the HSS a service profile, SP, in relationship with the subscription to the IMS of a user, the SP comprising a set of SP data usable by the S-CSCF for processing of services of said user, transmitting (4210) the set of SP data from the HSS to a S-CSCF, and controlling (4310) by the S-CSCF the processing of services of said user according to the set of SP data received from the HSS; wherein configuring (4110) the SP comprises configuring (4115) new SP data used to identify in the S-CSCF a controlling rule, said controlling rule comprising values for one or more timers for controlling by the S-CSCF the value of a time associated to the processing of services of said user. The method further comprises: configuring (4305) in the S-CSCF a controlling rule, said controlling rule comprising: a rule value that maps to a value of the new SP data, and, in relationship with the rule value, values for one or more timers for controlling by the S-CSCF a time associated to the processing of services of said user; wherein the transmitting (4210) the set of SP data from the HSS to a S-CSCF further comprises transmitting (4215) the new SP data.
