Embodiment 1

[0080] In this embodiment, the control point directly sends the operation indication information of the remote operation to be performed to the controlled point. specifically, Figure 4 It is a specific flowchart of the method for realizing remote media stream control in Embodiment 1 of the present invention. Such as Figure 4 As shown, the method includes:

[0081] Step 401, the control point generates operation instruction information according to the remote control operation to be performed.

[0082] In this embodiment, according to different remote control operations, the content of the generated operation indication information is also different.

[0083] In general, the operation indication information may include the following specific information: session indication information, media stream indication information corresponding to the session, operator corresponding to the media stream, association indication and reason information.

[0084] 1. Session indication i...

Embodiment 2

[0218] In this embodiment, the control point first acquires session state information of the controlled point, and then forms operation instruction information based on the information and sends it to the controlled point. specifically, Figure 9 It is a specific flowchart of the method for realizing remote media stream control in Embodiment 2 of the present invention. Such as Figure 9 As shown, the method includes:

[0219] Step 901, the control point acquires session state information of the controlled point.

[0220] In this step, the manner in which the control point obtains the session state information of the controlled point specifically includes: the control point sends a request message for obtaining session state information to the controlled point, and the controlled point sends the session state information after receiving the request message Give control points.

[0221] The control point can obtain the session state information of the controlled po...

Abstract

The embodiment of the invention discloses a method for realizing remote media flow control which comprises the following steps that: a control point sends an SIP request message carried with an operating instruct message to a controlled point, and remotely indicates a session operation and / or a media flow operation needed to be executed by the controlled point; after the controlled point receives the SIP request message, the controlled point executes the corresponding session operation and / or media flow operation according to the operating instruct message. With the method of the embodiment of the invention, the operation of appointed medial flows that the control point directly controls the controlled point can be realized. Further, an operating instruct for a plurality of sessions and corresponding media flows can be carried in the operating instruct message, so the aim of remote control of a plurality of sessions in an SIP request can be realized. The embodiment of the invention also discloses a communication system, control point equipment and controlled point equipment for realizing remote media flow control.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, communication system and equipment for realizing remote media flow control. Background technique [0002] Session Initiation Protocol (SIP) is one of the multimedia communication system framework protocols formulated by the Internet Engineering Task Force (IETF), and is a text-based application layer control protocol. It is independent of the underlying protocol and is used to establish, modify and terminate multimedia sessions on the IP network. In the SIP protocol, a multimedia session is composed of a group of multimedia senders and receivers and their data streams between each other. The session uses a SIP dialogue and follows the SIP rules when sending requests during the dialogue. A dialog is a SIP relationship between communicating parties that provides the necessary state information for routing and message sequencing between communicating parties. A SIP Use...
