Patent ID: 8768409

Claim:
A wireless communication terminal comprising a layered protocol structure to communicate with an asynchronous core network through a synchronous radio network, the wireless communication terminal comprising: a physical layer to communicate with a physical layer of the asynchronous core network through a physical layer of the synchronous radio network; a data link layer to communicate with a data link layer of the asynchronous core network through a data link layer of the synchronous radio network; and a network layer comprising an asynchronous call control (CC) entity and an asynchronous mobility management (MM) entity, wherein the asynchronous call control (CC) entity of the wireless communication terminal communicates with an asynchronous call control (CC) entity of the asynchronous core network without communicating with a synchronous call control (CC) entity of the synchronous radio network, and the asynchronous mobility management (MM) entity of the wireless communication terminal communicates with an asynchronous mobility management (MM) entity of the asynchronous core network without communicating with a synchronous mobility management (MM) entity of the synchronous radio network.
