Problems solved by technology
[0008] In some conference services, conference users join the cluster conference through INVITE from the network side, and the session description protocol (SDP) of INVITE does not carry the information to join the conference. At this time, It is necessary to establish a call with the MS through the SIP Server, and to play the conference user to collect the number to collect the information that the user wants to join the conference, but if the created conference is not in the SIP Server, the SIP Server will not be able to directly connect the conference user to the conference The SIP Server of the meeting finally causes the meeting users to fail to join the meeting normally

A method, apparatus and system for creating and joining the IP Multimedia Subsystem (IMS) are disclosed by the embodiments of the present invention, which belong to the telegraphy field and can effectively solve the problem of joining a group conference by the voice dialing in the prior art, and enable the users to join the conference normally when playing sound and receiving telephone number are required in joining the IMS group conference. Comparing to the prior art, the system provided by the embodiments of the present invention adds a global conference manager, which is used to distribute a globally unique conference number to the conference to be created, and store the conference number in the global conference index table; and search the information of the Session Initiation Protocol (SIP) server which the conference is disposed in according to the information of the conference to be joined. The technical solution of the embodiment of the present invention can adapt to the technical requirements of the large-scale extender for the IMS group conference service capacity.
Description
technical field [0001] The present invention relates to the technical field of telecommunications, in particular to a method for creating and joining an Internet Protocol Multimedia Subsystem (IP Multimedia Subsystem, IMS) cluster conference, a distribution system and a global conference manager. Background technique [0002] Session Initiation Protocol (Session Initiation Protocol, SIP) is a signaling protocol that implements real-time communication applications in an IP-based network, especially in an Internet-based network environment. The application target of SIP is in an Internet-based environment. Realize data, audio and video real-time communication and other multimedia applications. Parlay is an application programming interface (Application Programming Interface, API) of a telecommunication service. These interfaces cover various telecommunication network functions such as call control, short message service SMS / multimedia short message service MMS, positioning, b...
