Abstract
A serving call session control function unit (S-CSCF) is provided within an IMS-based service communication system in order to register a user of a mobile communication terminal for communication service in a mobile communication system. The IMS-based service communication system has several call session control function units and at least one interrogation call session control function unit (I-CSCF). The mobile communication system is equipped with at least one policy decision point unit (PDP). To select a suitable S-CSCF unit, user information is first determined using a user context server unit that is assigned to the policy decision point unit and network information is determined using a network context server unit. The user information and network information are interlinked in the policy decision point unit (PDP) and user-specific and/or network-specific selection criteria are derived from said information and are taken into consideration to select a suitable S-CSCF unit.
