摘要

Method for controlling multi-mode mobile communication terminal designed for handover between communication network and communication network assu00ecncrona su00ecncrona and its system of mobile communication ".The present invention relates to a method for controlling communication terminal and mobile communication system.In the control method of mobile communication terminal.A base station synchronous to a synchronous area placed in the region limit of an asynchronous area transmits a dummy pilot signal at the same frequency as that of the signal used in the communication systemMobile unit and triggers an asynchronous modem of terminal of mobile communication and move from area to area, asynchronous synchronous.Is built a cell handover at the limit between the areas of synchronous and asynchronous.And a base station for handover in the handover cell transmits a signal including the information of the system at the same frequency signal used in the asynchronous mobile communication system.Through the synchronous modem unit of the mobile communication terminal which enters the cell for handover.
