20090080353 | METHOD AND APPARATUS FOR TRANSMITTING MULTIPLE MULTICAST COMMUNICATIONS OVER A WIRELESS COMMUNICATION NETWORK - Apparatus and method for allocating bandwidth for multicast communications in a wireless communication network. The base station allocates certain bandwidth for handling multicast communications through a multicast communication channel. When a new multicast communication arrives, the base station assigns a predefined number of bandwidth to the multicast communication channel according to a predefined algorithm. A wireless device will monitor all slots in a multicast channel and discard all the packets not belonging to its call. | 03-26-2009 |
20090080357 | MULTICAST MESSAGING WITHIN A WIRELESS COMMUNICATION SYSTEM - Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message. | 03-26-2009 |
