According to the existing standard definition, the terminal/network completes DC negotiation through the Session Description Protocol (Session Description Protocol, SDP). In the same session, the terminal can negotiate multiple data channels. When the data channels have different Internet Protocol (IP) addresses, or different User Datagram Protocol (UDP) port numbers, or Stream Control Transmission Protocol (SCTP) port numbers , different SDP m lines need to be used for negotiation.

In the related technology DC negotiation process, after receiving the media negotiation request, the network side network element cannot determine whether the media negotiation request is used to request a data channel between the terminal and the terminal, or a data channel between the terminal and the network server. problem; and, in the operator network, there is also a problem that the network element on the network side cannot know whether the received media negotiation request needs to be processed by the local network or the remote network.
