Hybrid media gateway control function providing circuit-switched access to a packet-switched radio telecommunications network

摘要: A hybrid Media Gateway Control Function (MGCF) implemented in a 3G wireless telecommunications network that provides access to multimedia services and IP networks for mobile terminal operating circuit-switched (CS) mode. The MGCF includes CS-specific signaling mechanism exchanges control with radio (RAN) serving the terminal, SIP Call State (CSCF) accesses terminal. converter converts into signaling, sends mechanism. switching function within controls (MGW) route media payload from RAN destinations such as networks.
