Embodiment Construction

[0047] In order to make the purpose, 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 and specific embodiments.

[0048]Since the MBMS service is a service sent in broadcast mode and can be received by multiple users at the same time, it has its particularity compared with ordinary services; moreover, the recipient of the MBMS service is uncertain, and the system does not necessarily save all required Receive the user information of the MBMS service, and at the same time, it is impossible to notify each user of the paging of the MBMS service in consideration of efficiency. Therefore, the paging mode of common services is not suitable for paging of MBMS services.

[0049] In addition, MBMS services generally do not require high real-time performance, so this feature can be used when designing the paging mode of MBMS services to minimize the number of ...

Abstract

The embodiment of the invention provides a paging method of a multimedia multicast service, and the method comprises following steps, a network side sends a notice and dispatch signal of multimedia multicast service notice information in a shared control channel; the network side sends the notice information of multimedia multicast service in a down-going shared channel which has the same subframe with the shared control channel; the user equipment makes sure whether the notice information of multimedia multicast service exists according to the indication of the notice, and if the notice information exists, the user equipment can receive the notice information of multimedia multicast service according to the resource indicated by the dispatch signals. At the same time, the embodiment of the invention provides a multimedia multicast service paging system corresponding to the method. Through the method and the system, the paging of multimedia multicast service can be realized.

Description

technical field [0001] The invention relates to multimedia broadcast and multicast technology, in particular to a paging method and system for multimedia broadcast and multicast services. Background technique [0002] In order to effectively utilize mobile network resources, 3GPP proposed Multimedia Broadcast / Multicast Service (MBMS), which provides a point-to-multipoint service in which a data source sends data to multiple users in a mobile network, and realizes network resources Sharing to improve the utilization of network resources, especially the utilization of air interface resources. MBMS provides two modes: broadcast mode and multicast mode. MBMS can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services. [0003] 3GPP specifies the cells that carry MBMS services. There are two types of cells that can be used to carry MBMS services: [0004] 1. A cell using a specific frequen...
