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.

Mixed mobile communication system of asynchronous communication network and synchronous communication network having handover function of mobile communication terminal, and handover method in the same

The present invention relates to a clustering method for rosette scan images, comprising the steps of: (a) obtaining a subject image according to its rosette pattern; (b) converting the location information among the data of the subject image and arraying the converted information into a two-dimensional memory; (c) reading the image data arrayed in the two-dimensional memory from the first row and defining a portion of the data with continuous 1's as a partial cluster; (d) storing multiple partial clusters created upon the completion of the step (c) with respect to the said two-dimensional memory to the end; (e) examining the adjacency among the created multiple partial clusters; and (f) binding the adjacent partial clusters detected in the step (e) as an independent cluster.
