Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] like image 3 As shown, it is a schematic diagram of the EMBMS system architecture in the LTE system of the present invention. The BM-SC 30 is connected to a multimedia service source (Content Provider) 35 for receiving multimedia data services provided by the data service source, such service data includes but not limited to weather forecasts, news clips, sports game highlights and various advertisements. The UTRAN Access Gateway (AGW, E-UTRAN Access Gateway) 31 of each access gateway evolution is connected to the BM-SC 30 through the Gmb interface / Gi interface, and is used to complete the signaling interaction with the BM-SC 30; each evolved NodeB The (eNB) 34 is connected to the AGW 31 through the S1 interface to complete signaling interaction with the AGW 31 . Each eNB 34 is connected to each user terminal UE (not shown in the figure) through a U...

Abstract

The present invention discloses a resource allocation method and a system for a multimedia broadcast service in a 3G long-time evolution system, wherein, the method includes three steps. (1). after receiving the multimedia broadcast service instruction sent by a broadcast multicast service center, a central processing module initiates a resource query instruction to the subdistrict related to the multimedia broadcast service, determines the resource configuration information of sending the multimedia broadcast service according to the returned resource information and issues the determined resource configuration information to the subdistrict; (2). according to the received configuration information, the subdistrict determines if configuration resources are available, and returns a message to the central processing module, and the message determines if configurations are successful; thirdly; (3) the central processing module sets the successfully configured subdistrict as the single-frequency network (SFN) district of the multimedia broadcast service. The present invention sets each subdistrict related to the multimedia broadcast service to a SFN district, which is favorable to the realization of the macro-diversity of UE (user equipment). The resource configuration flow of the present invention is perfect, and realization is simple.

Description

technical field [0001] The present invention relates to a resource allocation technology for multimedia broadcasting services in a mobile communication system, in particular to a resource allocation method and system for multimedia broadcasting services in a 3G long-term evolution system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) has long recognized the importance of broadcasting and multicasting, and made efforts for this—3GPP Release 6 proposed Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service). MBMS is a point-to-multipoint service in which one data source sends data to multiple users, such as weather forecast, news clips, sports game highlights and other multimedia services, which realizes the sharing of core network and access network resources. MBMS includes two modes: broadcast and multicast. Both modes can use the service announcement function to indicate effective MBMS services. In the broadcast m...
