Embodiment Construction

[0038] The flow of the implementation method of the multimedia video system calling set in the present invention is as follows: image 3 shown, including the following steps:

[0039] In step s201, the initiating terminal sends a private calling set request message to the multimedia video system through the soft switch. Wherein, the initiating terminal first sends a private call set request message to the soft switch, and the soft switch encapsulates the private call set request message into a location request message and sends it to the multimedia video system.

[0040] In step s202, the multimedia video system sends a private calling set response message to the initiating terminal through the soft switch. Wherein, the multimedia video system first encapsulates the private calling set response message into a location confirmation message, and sends it to the softswitch, and then, the softswitch decodes the private calling set response message from the location confirmation m...

Abstract

The present invention provides a method for implementing call set in a multimedia video system: the initiating terminal sends a private call set request message to the multimedia video system through a soft switch; the multimedia video system sends a private call request message to the initiating terminal through a soft switch call set response message; the multimedia video system creates a multimedia video conference according to the private call set request message; the multimedia video system summons the terminals to participate in the conference to join the conference according to the conference information. In the present invention, the call set requests of all terminals are unified by the softswitch agent to interact with the multimedia video system, and the call set service authentication is uniformly performed on the soft switch to ensure the security of the multimedia video system; in addition, the present invention extends SIP The INFO message of the protocol carries the private call set message in the message body, and the soft switch transparently transmits the call set message of the terminal to the multimedia video system, which solves the problem of private network traversal of the call set.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a method for realizing a calling set of a multimedia video system. Background technique [0002] With the rapid development and popularization of Internet technology, people's demand for multimedia services is more and more extensive, among which video conferencing is widely used in large and medium-sized enterprises. The multimedia video system is specially used to provide users with multimedia conferencing functions. The structure is as follows: figure 1 As shown, it includes: gatekeeper 10, MCU (MultipointControl Unit, multipoint control unit) 20, multimedia conference management equipment 30, terminal 40, terminal 50 and terminal 60, wherein, soft switch 10 is used for managing user terminals, providing user access Into the multimedia video system, such as address translation, access control and bandwidth management for audio / video data streams; MCU20 mainly...
