Wireless network using shared traffic channel mode of operation for broadcast services
First Claim
1. For use in a wireless network, a base station capable of transmitting broadcast data over a shared traffic channel to a plurality of mobile stations in a coverage area of said base station,wherein said base station is capable of transmitting a first control message over said shared traffic channel to said plurality of mobile stations, said first control message operable to assign a shared public long code mask (PLCM) to said plurality of mobile stations, transmitting a second control message to said plurality of mobile stations, said second control message operable to assign a shared Walsh Code (WC) to said plurality of mobile stations, transmitting mobile station-specific information to a first target mobile station by transmitting in said broadcast data a first packet data unit containing a first local address identifier associated with said first target mobile station, transmitting multicast information to a first group of mobile stations by transmitting in said broadcast data a second packet data unit containing a second local address identifier associated with said first group of mobile stations,wherein said broadcast data comprises the first local address identifier and said mobile station-specific information, and wherein the first address identifier comprises fewer bits than the mobile station electronic serial number (ESN) value.

Abstract
A wireless network base station for transmitting broadcast data to a plurality of mobile stations in a coverage area of the base station. The base station transmits a first control message to the mobile stations that assigns a shared public long code mask (PLCM) to the mobile stations. The base station also transmits a second control message to the mobile stations that assigns a shared Walsh Code (WC) to the mobile stations. Thereafter, the base station transmits the broadcast data to the mobile stations using the shared PLCM and the shared WC.

9. For use in a wireless network, a method of transmitting broadcast data from a base station to a plurality of mobile stations in a coverage area of the base station using a shared traffic channel, the method comprising the steps of:
-
wherein said base station is capable of transmitting a first control message over said shared traffic channel to said plurality of mobile stations, said first control message operable to assign a shared public long code mask (PLCM) to said plurality of mobile stations, transmitting a second control message to said plurality of mobile stations, said second control message operable to assign a shared Walsh Code (WC) to said plurality of mobile stations, transmitting mobile station-specific information to a first target mobile station by transmitting in said broadcast data a first packet data unit containing a first local address identifier associated with said first target mobile station, transmitting multicast information to a first group of mobile stations by transmitting in said broadcast data a second packet data unit containing a second local address identifier associated with said first group of mobile stations, wherein said broadcast data comprises the first local address identifier and said mobile station-specific information, and wherein the first address identifier comprises fewer bits than the mobile station electronic serial number (ESN) value. - View Dependent Claims (10, 11, 12, 17, 18, 19)
