Abstract: A method and apparatus for multicasting data streams in a wireless radio communication system are provided. A server assigns a plurality of data streams amongst RF resources. One or more points-of-access of the wireless radio communication system are operable to transmit each RF resource to mobile communication devices. Responsive to a request from a mobile communication device for a selected one of the plurality of data streams, the server identifies the points-of-access that have not been assigned, and hence cannot transmit, the RF resource to which the selected data stream is assigned. An access controller instructs those points-of-access to deny association to the mobile communication device. The server then multicasts the selected data stream to the mobile communication device through one of the remaining points-of-access that can transmit the selected RF resource.
