Negotiation method, device, network equipment and terminal

Technical Field

The present invention relates to the field of data service technologies, and in particular, to a negotiation method, a device, a network device, and a terminal.

Background

In order to realize richer interaction and Data transmission capability in the VoIMS call, a Data Channel (DC) technology is currently introduced in the IMS system. The terminal/network completes the DC negotiation via session description protocol (Session Des cription Protocol, SDP) according to the existing standard definition. In the same session, the terminal may negotiate multiple data channels. When the data channels have different IP addresses, or different user data protocol (User Datagram Protocol, UDP) port numbers, or stream control transmission protocol (Stream Control Transmission Protocol, SCTP) port numbers, different SDP m lines need to be used for negotiation.

In the existing DC negotiation process, after receiving a media negotiation request, a network side network element has the problem that whether the media negotiation request is used for requesting a data channel between terminals or a data channel between a terminal and a network server cannot be judged; in addition, in the operator network, there is a problem that the network side network element cannot know whether the received media negotiation request needs local network processing or remote network processing.

In addition, for a DC application that involves the common use of both parties in a call, it is required that both party terminals have the same application program for providing the DC application, and the initiator terminal may acquire the application program/application page data when the user selects the DC application, and then establish a data channel with the opposite party for application data transmission. At this time, the receiving terminal receives the data channel establishment request from the initiator, so that the establishment of the data channel can be completed, but the application program/application service data corresponding to the data channel cannot be known and requested, so that the service data analysis and interaction of the data channel application cannot be realized.

Therefore, in the data channel negotiation process, the receiving end of the media negotiation request cannot accurately execute the data channel establishment, and the problem of service analysis and interaction is solved.
