Embodiment 1

[0058] see figure 2 , this embodiment provides a method for actively transferring session control rights. In this embodiment, client A is used as the first client, and client B is used as the second client. The method includes the following steps:

[0059] Step 101: Client A sends a request to the server to transfer a certain session. The message may contain information about the session to be transferred, such as session identification information, specifically session ID, URI (Universal Resource Identifier, Uniform Resource Identifier), and the like. If the client A controls multiple sessions with the server at the same time, the message also includes identification information that can uniquely confirm the session. Client A specifies the destination to be transferred in the message. The transfer destination in this embodiment is client B. You can confirm the identity of client B by specifying the IP address of client B or the user name of client B. information. If no de...

Embodiment 2

[0070] see image 3 , this embodiment provides a method for passively transferring session control rights. In this embodiment, client A is used as the first client, and client B is used as the second client. The method includes the following steps:

[0071] Step 201: client B sends a request to the server, requesting to take over the control right of a certain session. In this embodiment, client B requests to take over a session control right of client A. The session to be received can be directly specified in the message, such as the session identification information controlled by client A, that is, session ID, URI, etc.; it can also be specified indirectly, such as the identification information of client A, which includes client A's IP, username etc. If client B wants to forcibly take over a session, it specifies in the request message that the session is to be forcibly taken over. When the priority of client B is higher than that of client A, client B has a session forc...

Embodiment 3

[0110] see Figure 5 , this embodiment provides a system for transferring session control rights, including: a first client, a second client, and a server;

[0111] The first client is used to send a request to the server to transfer the control right of the session to the second client;

[0112] The server is used to receive the request sent by the first client, negotiate with the second client for session transfer according to the request, and after the negotiation is passed, the first client disconnects the control right of the session;

[0113] The second client is used for taking over the control right of the session after the first client disconnects the control right of the session.

Abstract

The invention provides a method, a system and a server for transferring conversation control and belongs to a communication technique field. In order to implement transfer of conversation control, the invention provides the method for transferring conversation control. The method comprises the following steps that a first client terminal requests a server to transfer control of conversation to a second client terminal; the server and the second client terminal negotiate conversation transfer; and after the agreement is achieved, the first client terminal disconnects the control of the conversation, and the control of the conversation is transferred to the second client terminal. The invention further provides the system for transferring conversation control, which includes the first client terminal, the second client terminal and the server. The invention also provides the server, which includes a receiving request module, a negotiation module, and a control transfer module. With the technical scheme provided by the invention, conversation control transfer on different client terminals is implemented, which facilitates a user to better control conversation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and server for transferring session control right. Background technique [0002] The current media on demand basically adopts the separation of control signaling and media streams. see figure 1 , providing the principle of media on demand. For example, client A orders a multicast stream, other clients B and C join the multicast group to watch, and client A sends the control stream. The terminal can be a PC, a TV (set-top box), or a mobile phone. [0003] RTSP (Real Time streaming Protocol, real-time streaming protocol) is a commonly used media transmission control protocol in the world at present. The on-demand process of RTSP is as follows: [0004] The RTSP client initiates a TCP (Transmission Control Protocol, Transmission Control Protocol) connection to the RTSP server. After the connection is established, the client and the server exchange session...
