Patent ID: 7512090

Claim:
A system for routing calls having different call types in a 3GPP/3GPP2 wireless communications network made to a called party single point of contact comprising: an Internet Protocol Multimedia Subsystem (IMS) Call Session Control Function (CSCF) network entity receiving Subscriber Universal Destination Identifier (SUDI) call requests from a calling party multimedia enabled mobile phone via a radio area network, each SUDI call request corresponding to a different call made to a called party single point of contact, at least some of the SUDI call requests including a session identifier and a SUDI defining a single point of contact for calls having different call types made to a called party and a media descriptor defining the type of media to be transferred by the call and an indicator of the originating host, the OSOF network entity executing call setup and call session control for each call and determining a call type for each call from the corresponding SUDI call request including: determining if a protocol for the SUDI call request can support multiple call types, wherein if the SUDI call request protocol cannot support multiple call types then determining the call type from the SUDI call request protocol, and wherein if the SUDI call request protocol can support multiple call types then determining the call type from the media descriptor in the SUDI call request; means for determining a call type for each call; and means for selecting a call-type-specific destination identifier for each call from a plurality of called party destination identifiers based on the call type, wherein the CSCF network entity routes the calls to the called party using the selected call-type-specific destination identifiers.
