Problems solved by technology

[0011] In practical application, the above solution has the following problems: such as PoC and other IP multimedia system services waste transmission and air interface resources in the realization of broadcast and multicast services
[0012] The main reason for this situation is that the existing IP multimedia system services implement broadcast and multicast services by sending data to all receivers in a point-to-point manner, which occupies a large amount of transmission and air interface resources
Although the MBMS service can make more effective use of transmission and air interface resources, its method has not been used in the existing IP multimedia system services

Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0061] The core of the present invention is that the application server establishes an MBMS group for the IP multimedia system service through the control center for managing broadcast and multicast services, acquires the group ID, and issues the group ID to the user terminal joining the service. Afterwards, the user terminal activates the MBMS group according to the received group identifier, and uses the channel of the MBMS group to carry the service after the activation is successful.

[0062] As shown in Figure 4, the bearer system of the IP multimedia system service of the present invention includes at least one user terminal using the IP multimedia system service, a control center for managing the multimedia broadcast multicast service, and a control center f...

Abstract

The related IP multimedia system comprises: applying MBMS group mark to BM-SC for current business, using AS to notify the client terminal added in the business apply MBMS way to load the business; initiating the activation process by user terminal; building P2P channel by AS, then loading business by MBMS way; or direct using MBMS way till there are some user terminals. This invention occupies less transmission and interface resource.

Description

technical field [0001] The invention relates to an IP multimedia system, in particular to a bearing method and system for IP multimedia system services. Background technique [0002] With the development of the third-generation mobile communication technology, the third-generation mobile communication can provide services with a higher data rate than the second-generation mobile communication, thereby supporting various business forms. And with the development of broadband networks, mobile communications will not be limited to traditional voice communications, but multimedia services that combine audio, video, pictures, text and other media types will gradually develop. The combination of data services such as browsing, positioning information, push services, and file sharing can meet various needs of users. For example, message services include instant messages, chat rooms, and multimedia short messages, and video services include entertainment, multimedia information, and...
