ABSTRACT:
The present invention relates to a method for selecting an Application Server in an Internet Protocol multimedia network upon reception of an Internet Protocol Multimedia call destined to a called party terminal. This method at first comprises the step of a call session control network element intercepting the incoming IP multimedia call. Subsequently, the call session control Network element upon intercepting of the incoming IP multimedia call activates a dedicated primary application server. The primary application server, upon analysis of the incoming IP multimedia call presents the incoming IP multimedia call to the called party terminal together with a set of service applications for answering said incoming call. This set of service applications is determined in the analysis. The call session control Network element receives a selection of at least one service application from the set of service applications forwarded by said called party terminal.
