Meanwhile, in the case of the asynchronous method of the IMT-2000 system, a GSM-MAP network that is used asynchronously or an ANSI-41 network that is used synchronously may be used as the core network according to the May 1999 OHG requirement decision.

In order to be able to operate adaptively to these two structures, the asynchronous terminal, unlike the asynchronous terminal used in the conventional asynchronous mobile communication system, is a CC for GSM-MAP core network service in Layer 3 of the protocol stack structure. (Call Control), MM (Mobility Management) protocol entity, and both CC and MM protocol entity for ANSI-41 core network service, and the protocol interface must be adaptively converted according to the connected core network.
