Embodiment Construction

[0016] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0017] IMS multimedia communication mainly includes two aspects: signaling negotiation on the control plane and media data (content) transmission on the user plane. The former generally uses the SIP (Session Initiation Protocol) protocol, and the latter generally uses the RTP (Real- time Transport Protocol, real-time transport protocol) protocol. figure 1 is an architecture diagram of an IMS multimedia communication system according to an embodiment of the present invention, such as figure 1 As shown, generally involves terminal 10 (UE-A and UE-B) and IMS core network 20 (UE-A's home network and UE-B's home network), the following embodiments of the present invention mainly focus on terminal 10 and ...

Abstract

The invention discloses an IP multimedia subsystem (IMS) multimedia communication method and system as well as a terminal and an IMS core network, wherein the IMS multimedia communication method comprises the following steps: the terminal carries out signaling negotiation with the IMS core network, and establishes an IPsecurity-encapsulate secure playload (IPSec-ESP) security association for media transmission between the terminal and the IMS core network during the signaling negotiation process; and media content transmission is carried out between the terminal and the IMS core network through the IPSec-ESP security association for media transmission. By means of the invention, the safety of the media content transmitted between the terminal and the IMS core network is ensured, the safety problem of multimedia communication under the IMS in the correlation technique is solved, and the multimedia content is prevented from being maliciously stolen and falsified by others when being transmitted between the terminal and the IMS core network.

Description

technical field [0001] The present invention relates to the communication field, in particular to an IMS multimedia communication method and system, a terminal and an IMS core network. Background technique [0002] With 3G (the 3 rd Generation, third generation) network development, more and more multimedia services can be deployed under the IMS (IP MultiMedia Subsystem, IP Multimedia Subsystem) core network, such as video sharing (VS, Video Sharing), IP-based voice communication ( VoIP, Voice over IP), IP-based video and voice communication (V2IP, Video and Voice over IP), and push-to-talk (PoC, Push To Talk over Celluar), etc. These services are transmitted using the IP protocol instead of the SS7 (Signal System 7, No. 7 signaling system) of the 2G network. [0003] The introduction of the IP protocol makes it very convenient to deploy packet switching services in the IMS core network, and also makes the IMS core network completely open and easy to access. Due to the d...
