METHOD FOR HANDOVER OF MOBILE COMMUNICATION TERMINAL IN MIXED MOBILE COMMUNICATION NETWORK OF ASYNCHRONOUS AND SYNCHRONOUS COMMUNICATION NETWORK

摘要

Disclosed is a method for handover of a mobile communication terminal by using an Interworking Interoperability Function (HF) unit for signal exchange between asynchronous and synchronous mobile switching centers and a protocol (ISUP) for message transmission between the mobile switching centers in a hybrid mobile communication system including both an asynchronous network and a synchronous network.
