AI Technical Summary

Technical Problem

The fixed protocol stack of existing IMS data channels cannot meet the diverse security needs of different communication scenarios and is less flexible.

Method used

By negotiating whether to include the DTLS protocol in the data channel of the IMS session, it allows flexible selection of the protocol stack in different communication scenarios, such as using the UDP/DTLS/SCTP protocol stack or the UDP/SCTP protocol stack.

Benefits of technology

It improves communication flexibility, can adapt to communication scenarios with different security needs, reduces unnecessary encryption times, improves data transmission efficiency and reduces the performance overhead of network equipment.

Abstract

The invention provides a communication method and device and a communication system, and relates to the technical field of communication. In the method, a session description protocol (SDP) proposal party and an SDP responder can negotiate whether a protocol stack of a data channel of an IMS session in which the two parties participate comprises a datagram transport layer security (DTLS) protocol or not, so as to adapt to communication scenes with different security requirements and improve the flexibility of communication. Wherein the SDP proposal party is one terminal in the IMS session, and the SDP responder is another terminal in the IMS session, or the SDP proposal party is one terminal in the IMS session, and the SDP responder is network equipment in a communication network in which the IMS session is located, or the SDP proposal party is network equipment in the communication network in which the IMS session is located, and the SDP responder is one terminal in the IMS session.
