摘要

A mode of mobile communication, in which voice communication (CV) is switched from one state to another, and a voice communication packet (PPCV) carrier is used to access the first communication system in a wireless access network (AR) which does not support c-line communicationIn the first communication plan, AR is installed in the second communication plan through the carrier of a switching line and a central network to realize the CV of a state.CM's method includes the following steps: making EM modulate an AR in the connected destination, from the AR in the first AC plan to the AR in the second AC plan. Make a flow management node (NGM) of RTM store specific information, indicating that the connection destination of EM has been transferred; make NGM receive a request to delete papcv carrier in a service gateway device of RTM; and make NGM send. In the service gateway system, a response signal to clear the un manned in the request to delete the un manned,Do not give an instruction to em or an instruction in the first communication system to release PPCV, if GNM stores preset information
