Problems solved by technology
[0013] For the MBS-MAP message, if only the information element MBS-MAP_IE() of the DL-MAP message is used for indexing, since the location information contained in the corresponding information element is only for the OFDMA symbol offset information where the MBS-ZONE is located , so the actual physical channel resource occupied by the MBS-MAP message cannot be located

The present invention discloses a method of realizing indicating resource of MBS, and the method comprises: a Down Link-MAP (DL-MAP) message sent by a Base Station (BS) carries resource information associated Multicast and Broadcast Service (MBS); receiving the DL-MAP message sent by BS, Mobile Station (MS) judges whether the service information associated with MBS comprised in this message is identical to that reserved by the MS itself, if yes, the MS determines the physical channel resource occupied by MBS according to the resource information which is associated with MBS and carried in this message. The present invention also discloses another method of realizing indicating resource of MBS. The present invention solves the problem that the prior art cannot directly perform resource indication upon multicast service. Through the scheme of the present invention, position of the physical channel resource occupied by the MBS-MAP message corresponding to multicast service can be determined, and various specific positioning measures are provided thereof.
Description
technical field [0001] The present invention relates to the physical resource indication technology of multicast service, more precisely, relates to a method for realizing multicast service resource indication. Background technique [0002] With the rapid development of the Internet, a large number of multimedia services have emerged, some of which require multiple users to receive the same data at the same time, that is, multicast the data, and the involved application services include video on demand, TV broadcasting, video Conferences, online education, interactive games, etc. [0003] Multicast service is a technology for transmitting data from one data source to multiple targets, including multicast and broadcast. For the broadcast service, in the traditional mobile network, the Cell Broadcast Service (CBS, CellBroadcast Service) only allows low bit rate data to be sent to all users through the broadcast channel shared by the cell, which belongs to the message service....
