MULTI-NETWORK COMMUNICATION METHOD AND MULTI-NETWORK COMMUNICATION SYSTEM

The present application discloses a multi-network communication method and a multi-network communication system. The method comprises: when a multi-mode terminal receives a calling request initiated by a target terminal to a first call object in a first network, invoking a call mapping relationship between the first call object and call objects in a second network, and determining a second call object corresponding to the first call object in the second network on the basis of the call mapping relationship; initiating a call request to the second call object by means of the multi-mode terminal; and when it is determined that the call request of the multi-mode terminal is successful, sending first speech information corresponding to the first call object to the second call object, simultaneously acquiring second speech information corresponding to the second call object, sending the second speech information to the first call object, and sending to each second call object third speech information of call objec
