Problems solved by technology

This leads to increased complexity when the IMS network needs to be upgraded
[0017] Other issues associated with handling alias identities are the need for additional database requests and more logic to be executed in the application server

Embodiment Construction

[0034] Briefly described, the present invention provides a solution in which the data model of the IMS network and the setup of the HSS and application servers are simplified and the performance of handling service requests is improved, especially considering memory requirements and latency.

[0035] image 3 A first embodiment for handling service requests in IMS is illustrated. In a first step 3:1 , provisioning system 300 creates all required data, including user identities defined as master user identities and any known alias identities, and forwards this data to HSS 301 . The provisioning process may be initiated by a user requesting that a service provider (not shown) connected to the provisioning system assign an alias identity to a user identity identified as a primary user identity. A master user identity is a user identity with a specific set of services connected to the master user identity, which exists when the user customizes the corresponding set of services. ...

Abstract

A method and arrangement for handling a service request (3:5) in a session control unit (302) in a multimedia network is provided. Upon receiving a service request (305) from a user equipment (304) ina session control unit, a service profile associated with the user-identity of the service request is checked in order to find the application server (303) to which said service request is to be routed to. Before the service request (306) is routed (3:8) to the application server, an ensuring entity ensures that the service request will include a primary user-identity. In the application server,the primary user-identity is used for finding stored data, which is necessary for executing the requested service.

Description

technical field [0001] The present invention relates generally to efficient handling of service requests in multimedia networks, and more particularly to service requests involving alias identities. Background technique [0002] The IP Multimedia Subsystem (IMS) is a Session Initiation Protocol (SIP)-based architecture that creates a common platform to enable wider adoption of advanced Internet-based multimedia services and packet-switched networks. [0003] exist figure 1 In , the conventional procedures in an IMS network for registering user equipment with IMS and for requesting IMS-based services are illustrated. In this figure, only basic nodes are presented, while any intermediate nodes not affected by the present invention are omitted. [0004] Among other functions, a Serving-Call Session Control Function (S-CSCF) node is a SIP server or session control element that handles registration requests received from user equipment registered to the IMS. An S-CSCF node tha...
