MOBILE COMMUNICATION SYSTEM AND METHOD FOR PACKET HAND-OVER BETWEEN ASYNCHRONOUS COMMUNICATION NETWORK AND SYNCHRONOUS COMMUNICATION NETWORK, AND MOBILE COMMUNICATION TERMINAL THEREFOR

摘要

The present invention using a number redial message transmitted in an asynchronous network, the mobile communication terminal is a mobile communication system for enabling a packet handover to the asynchronous network and a synchronous manganese so as to be connected to a synchronous network and a packet hand-over method as this for relates to a mobile communication terminal.; The present invention includes the steps of: the asynchronous mobile communication system providing a packet service to a multi-mode multi-band mobile communication terminal; If the asynchronous mobile communication system and a radio communication environment between the mobile terminal satisfies the call redial request condition, receiving a pilot signal strength information transmitted from the mobile communication terminal; Comprising: call based on the pilot signal strength information of the terminal generates a redial message; And transmits the generated call redial message to the mobile communication terminal, the mobile communication terminal is synchronous mobile communication system, and including the step of so as to be connected, the call redial message generated by the handover request asynchronous network, a multi-mode multi-band mobile communication since the service to the terminal, there is an effect that the time that you have performed a packet handover to the synchronous network in an asynchronous network, the mobile communication terminal to reconnect the synchronous network and a packet call can be shortened.
