ABSTRACT:
The invention concerns a method (200) and system (100) for improving the efficiency of a mobile station (112) during a listening interval (310). The method can include the step of setting (212) a paging message indicator (414) or a neighbor advertisement message indicator (416) in which the paging message indicator indicates whether a paging message (314) is the last paging message designated for the mobile station in the listening interval and the neighbor advertisement message indicator indicates the presence of a neighbor advertisement message (316). The method can also include the step of transmitting (214) the paging message indicator or the neighbor advertisement message indicator to the mobile station. Based on these indicators, the mobile station can selectively enter a sleep state during and/or after the listening interval to conserve battery life.
