Problems solved by technology

[0002] The 3rd Generation Partnership Project Release 6 (3GPP R6) protocol can implement multimedia broadcast and multicast services, but the R6 protocol has not yet been formulated, and it will take a long time for mature products to be launched on the market
When the local streaming media system forwards the streaming media of the center, even if an emergency occurs locally in a certain area, the emergency event cannot be released to the public immediately, which makes the streaming media live broadcast in the CMB business lack of timeliness

Embodiment Construction

[0037] The core idea of ​​the present invention is: the local stream media server receives the switching request from the start local stream media live broadcast of local CMS, stops receiving the global stream media of center live broadcast, receives and forwards the area stream media of local live broadcast; In local stream media server After detecting that the local live broadcast is completed, the local streaming media server ends the local live broadcast service, receives and forwards the global streaming media.

[0038] The present invention realizes the switching and playing of the global / regional streaming media by setting a switching module for controlling the switching of the global / regional streaming media live broadcast in the local streaming media server.

[0039] 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 with reference to the accompanying drawings ...

Abstract

The present invention discloses realizing stream media switching method. In Cell Multimedia Broadcast (CMB) service, local stream media server receives switching request of starting up local stream media living broadcast from local content management systems, then stopping receiving center living broadcasted global stream media and switching as receiving and retransmitting local living broadcast area stream media; after local stream media server detecting local living broadcast completion, said local stream media server ending local living broadcast service, and switching back receiving and retransmitting global stream media. The present invention also discloses a stream media server, through switching module set in local stream media server to control global/area stream media living broadcast switching and playing. The present invention ensures stream media living broadcast timelinest in CMB service.

Description

technical field [0001] The invention relates to a mobile communication broadcasting technology, in particular to a method for realizing streaming media switching in Cell Multiple Broadcast (CMB, Cell Multiple Broadcast) service and a streaming media server. Background technique [0002] The 3rd Generation Partnership Project Release 6 (3GPP R6) protocol can implement multimedia broadcast and multicast services, but the R6 protocol has not yet been formulated, and it will take a long time for mature products to be launched on the market. Wideband Code Division Multiple Access (WCDMA) products of R99 and R4 protocols have been commercialized, but they can only provide point-to-point live streaming and on-demand services for each user. [0003] In view of this, the prior art provides Cell Multiple Broadcast (CMB, Cell Multiple Broadcast) services, which can implement broadcast / multicast services in WCDMA R99 and R4 protocol products. [0004] The CMB service is a simplified Mu...
