Patent ID: 7298713

Claim:
A method of processing an incoming message in a wireless communications network, the network comprising a plurality of wireless transmit/receive units (WTRUs) and at least one recipient list associated with at least one message, the method comprising: (a) determining whether the incoming message is a duplicate of a message associated with the recipient list; (b) if the incoming message is a duplicate of a message associated with the recipient list as determined in step (a), identifying a message address status of one or more WTRUs for the incoming message, wherein the message address status indicates whether a WTRU is identified for receipt of the incoming message, and adding the identity of the WTRUs that are not already on the recipient list to the recipient list; (c) assigning destination identifiers and pointers in a frame format which associates the added WTRUs to the message associated with the recipient list; (d) adjusting a message transmission time delay parameter used by the network such that each of the WTRUs has sufficient time to prepare for the reception of the incoming message; and (e) transmitting a single instance of the incoming message to all WTRUs identified for receipt of the incoming message.
