VOICE TRANS-CODING METHOD FOR HAND OVER FROM ASYNCHRONOUS MOBILE COMMUNICATION NETWORK TO SYNCHRONOUS MOBILE COMMUNICATION NETWORK

摘要

When the present invention requests a handover to a handover access network of the asynchronous mobile communication network according to the handover request of that, the mobile communication terminal for voice transcoding method is the exchange of the synchronous mobile communication network, from the asynchronous mobile communication network, handover If the exchange of the asynchronous mobile communication network according to the request is determined that the handover to the determined handover type, and synchronous mobile communication network, from the asynchronous mobile communication network, and driving the transcoder via a predetermined procedure, the exchange of the asynchronous mobile communication network, the dual by a stack received by the home location register requesting the subscriber information of the mobile communication terminal to the requesting handover to the synchronous mobile communication network, the dual-band / support dual-mode mobile communication terminal a synchronization in an asynchronous mobile communication network using a different speech coding scheme that handover when a mobile communication network to the mobile communication network, By supporting document appropriate voice transcoding has the effect that can provide seamless voice of the handover.
