A method and apparatus is provided to efficiently assign addresses for a mobile station ( 110 ) that monitors one or more broadcast groups. The mobile station ( 110 ) determines ( 210 ) at least one broadcast group to monitor. A broadcast server ( 150 ) determines ( 220 ) the broadcast time for the monitored broadcasts group(s). A broadcast server ( 150 ), mobile switching center ( 130 ), or mobile station ( 110 ) then determines ( 230 ) an address for the mobile station ( 110 ) that minimizes the wake up times for the mobile station for monitoring the chosen broadcast group. Preferably, the address is assigned a wake up time corresponding to a broadcast time for a monitored broadcast group. Further, a second preferred address may be determined ( 450 ) that is assigned to a second broadcast group. The mobile station ( 110 ) is registered ( 430 ) under the chosen address(es) if the mobile station ( 110 ) is not already assigned to one of the chosen addresses.
