Embodiment

[0066] reference figure 2 When the terminal 1 needs to use the IM multi-party conference function of the present invention, it first creates an IM multi-party conference on the IM server. The data stream for creating IM multi-party conferences uses standard SIP protocol, figure 2 The data flow of the process is illustrated:

[0067] The first step is to set terminal 1 as the creator of the IM multi-party conference and send an INVITE message to the IM server. The Request-Line field of the message indicates that it is a request message to create an instant message multi-party conference, where imc-Factory is a system convention for request messages to be routed to the IM server. The message parameter indicates that the media type is an instant message. The INVITE message information is as follows:

[0068] INVITE sip:imc-Factory@conf.example.com SIP / 2.0

[0069] ......

[0070] m=message 10600 UDP 520

[0071] Step 2: After the IM server receives the INVITE request to create an IM ...

Abstract

The invention relates to a multiparty communication technology in the network communication field, and discloses a multiparty communication method based on SIP protocol. The technical scheme is that: a, a terminal requests an IM server to establish an IM multiparty conference; b, a terminal participating in the IM multiparty conference invites other terminals to join in the conference; c, a terminal participating in the IM multiparty conference drives another terminal participating in the IM multiparty conference out of the IM multiparty conference; d, the terminals participating in the IM multiparty conference send an instant message to and receive an instant message from each other; e, the terminals participating in the IM multiparty conference do not comprise an initiator, and exit the conference; f, when the conference initiator exits the conference or all participants of the conference exit the conference, the IM multiparty conference is ended; and g, before the IM multiparty conference is ended, all users participating in the conference are informed of a minutes link address. The invention is applied to a multiparty conference system.

Description

Technical field [0001] The present invention relates to a multi-party communication technology in the field of network communication, and particularly relates to an IM (Instant Message) multi-party conference creation process and a user joining and user exiting process in a SIP (Session Initiation Protocol) system. Background technique [0002] In an IM multiparty conference, the message sender and conference participants send and receive instant messages through the communication network. In a message exchange process, the party sending the message is called the message sender, and the participant receiving the message is called the message receiver. The sender of the message can be a terminal, a WEB user, or other application server. In the IM multi-party conference system, it also includes functions such as authority control, meeting minutes storage and retrieval, and user management. [0003] With the increasing market demand for presence and IM, various implementation method...
