Patent ID: 6901058

Claim:
A system providing native physical and link layer support for handling multicast messaging in a wireless telecommunication network operating to communicate with mobile stations according to a CDMA air-interface standard, the mobile stations being members of a multicast group, said system comprising: a base station transceiver (BTS) for communicating with the mobile stations over the air interface; and a base station controller (BSC) for including a packet control function, the BSC for controlling the BTS and assigning Walsh codes for use in message processing by the BTS and by the mobile stations, wherein the BSC assigns a first multicast Walsh code for use by the mobile station in processing multicast control messages for transmission to the mobile stations belonging to the multicast group and wherein the BSC assigns a second multicast Walsh code, “for use by the BTS in processing messages for transmission to the mobile stations being members of the multicast group” said packet control function further comprising a multicast reflection function for receiving multicast messages that have been processed by a mobile station using a long-code mask and processing the multicast messages using the second multicast Walsh code for transmission by the BTS to the mobile stations being members of the multicast group.
