Description

A method and system for allocating speaking rights for session establishment

technical field

The invention relates to the field of broadband network communication, in particular to a multi-party multimedia communication technology in broadband network communication, specifically a method and system for allocating speaking rights for session establishment.

Background technique

With the development of broadband networks, mobile communications will not be limited to traditional voice communications, but multimedia services that combine audio, video, pictures, and texts will gradually develop. , Web page (WEB) browsing, positioning information, push service (PUSH), file sharing and other data services can meet various needs of users. For example:

Message service: instant message and chat room, multimedia short message;

Video business: entertainment, multimedia information, daily communication;

E-commerce: product catalog, search engine, shopping cart, order management, payment;

Games: single player games, group games;

Positioning business: tracing, guide, alarm;

Personal assistant: address book, calendar, bookmark management, file storage, event reminders, and e-mail.

Driven by the various applications mentioned above, the 3GPP standard organization has launched the IP-based Multimedia Subsystem (IMS) architecture, which aims to use a standardized open structure in the communication network to realize a variety of multimedia applications, providing Give users more choices and richer feelings.

With the development of network technology, multi-party communication has become a common business. In order to realize multi-party communication, a unified control point must be managed to ensure the consistency and real-time management. For example, if a user requests to send audio, the system needs to have one and only one control point to make a decision. Such as PoC system, conference (Conference) system. Among them, the PoC system is a centralized control multi-party multimedia communication system.

In the prior art, when a session is established, the system will assign the speaking right to the session establisher by default. That is: the user who establishes a session (point-to-point, ad hoc, pre-established) will be assigned the floor by default by the system. As shown in Figure 1:

User 1 first sends an Invite request, and the server forwards the Invite request to User 2 and User 3 after receiving the Invite request. After receiving the Invite request, user 2 returns a 200 OK message, and this message reaches user 1 through the server. After receiving the Invite request, user 3 returns a 200 OK message to the server, and the call establishment process is completed. By default, the server assigns the session right to user 1, the session creator. User 1 transmits media data to user 2 and user 3 via the server, so that user 1 establishes a media channel with user 2 and user 3 for dialogue.

The defect of the prior art is that, because the system assigns the speaking right to the user who establishes the session by default, but in some sessions the establisher does not necessarily need to speak, and in some special groups, the management of the speaking right is Completed by designated units or users, all granting of speaking rights needs to be decided by these units or users. Therefore, in these cases, the speaking right should not be directly assigned to the user who establishes the session by default.
