In a specific implementation scenario, please refer to fig. 2 in combination, where fig. 2 is a relationship diagram of a first embodiment of communication connections of devices in a communication method between wide and narrow networks provided in the present invention. As shown in fig. 2, a first network terminal 11 communicating in a first network needs to transmit multimedia data to a second network terminal 21 communicating in a second network, and since the first network terminal 11 and the second network terminal 21 communicate in different networks, the first network terminal 11 cannot directly transmit the multimedia data to the second network terminal 21. In this implementation scenario, the first network terminal 11 sends multimedia data to the second network terminal 21 through the first network server 12 and the second network server 22. The first network server 12 and the first network terminal 11 perform communication traffic in a first network, and the second network server 22 and the second network terminal 21 perform communication traffic in a second network. In this implementation scenario, the first network is a broadband network, the first network terminal 11 is a broadband terminal, the second network is a narrowband network, and the second network terminal 21 is a narrowband terminal. In other implementation scenarios, the first network may also be a narrowband network, the first network terminal 11 may also be a narrowband terminal, the second network may also be a broadband network, and the second network terminal 21 may also be a broadband terminal.
Specifically, the first network terminal 11 transmits a call message for calling the at least one second network terminal 21, which includes the first media negotiation information, to the first network server 12. After receiving the call message, the first network server 12 establishes a connection with the second network server 22 based on the call message, in this implementation scenario, the first network server 12 and the second gateway server 22 are directly connected, in other implementation scenarios, a gateway is provided between the first network server 12 and the second gateway server 22, and the first network server 12 and the second gateway server 22 are connected through the gateway.
In this implementation scenario, the first media negotiation information is NVOC (digital voice compression) media negotiation information, and in other implementation scenarios, the first media negotiation information may also be AMR (Adaptive Multi-Rate) media negotiation information.
After the first network server 12 establishes a connection with the second network server 22, the second network server 22 is notified that the first multimedia data of the first encoding scheme that can be supported by the second network terminal 21 is about to be received. In this implementation scenario, the first network server 12 forwards the received first media negotiation information to the second network server 22, so that the second network server 22 knows that it is about to receive the first multimedia data in the first coding mode that can be supported by the second network terminal 21. In this implementation scenario, the second network terminal 21 receiving the multimedia message is a narrowband terminal, and the first encoding mode is an NVOC encoding mode.

After receiving the multimedia message, the first network server 12 forwards the first multimedia data to the second network server 22 through the connection established in step S101, so that the second network server 22 transmits the first multimedia data to the second network terminal 21.
Since the first multimedia data is the first encoding mode that the second network terminal 21 can support, the second network terminal 21 can directly read the content of the multimedia message, without transcoding the first network server 12 when forwarding the first multimedia data to the second network server 22, which can effectively avoid error code caused by transcoding.
It should be noted that in this implementation scenario, there is only one second network terminal 21, and in other implementation scenarios, there may be multiple second network terminals 21, and the second network server 22 forwards the multimedia message to these second network terminals 21 at the same time.

In this implementation scenario, the first network server 12 forwards the received first media negotiation information to the second network server 22, so that the second network server 22 knows that it is about to receive the first multimedia data in the first encoding mode that can be supported by the second network terminal 21.
In this implementation scenario, since the second network terminal 21 receiving the multimedia message is a narrowband terminal, the first encoding mode is an NVOC encoding mode, and the second encoding mode is an AMR encoding mode.
