Abstract
In the mobile communication system, asynchronous and synchronous Mobile Switching Centers (MSCs) are interconnected via an Interworking Interoperability Function (IIF), and are connected to a Dual stack Home Location Register (D-HLR). The D-HLR stores and manages asynchronous subscription and synchronous subscription information of the mobile communication terminal. The IIF stores and manages the synchronous mobile communication system information, receives the synchronous subscription information of the mobile communication terminal from the D-HLR, transmits synchronous system information and the synchronous subscription information of the mobile communication terminal to the synchronous MSC and receives a response from the synchronous MSC, and requests the asynchronous MSC to release a wireless connection when the mobile communication terminal and the synchronous mobile communication system are interconnected and notification of completion of the handover is provided.
