Abstract: The present invention discloses a method, a system and apparatus of realizing indicating resource of MBS. 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.
