Patent ID: 7043256

Claim:
In a communication system having a network part and a mobile station selectably operable to communicate with the network part by way of a radio air interface, wherein the network part comprises a first access point defining a first coverage area and at least a second access point defining at least a second coverage area, the mobile station operable in an active state and at least a dormant state, an improvement of apparatus for facilitating initiation of a communication session with the mobile station, the mobile station forming a terminating node, said apparatus comprising: a location index for indexing together positional indicia associated with the mobile station forming the terminating node, wherein the positional indicia indexed at said location index identifies in which of the first and at least second coverage areas, respectively, that the mobile station forming the terminating node is positioned; and a page message generator embodied at the network part, said page message generator for generating a page message for broadcast upon the radio air interface throughout an area responsive to the positional indicia indexed at said location index to alert the mobile station of an invitation to initiate the communication session with the mobile station, the page message forming a wake-up indicator, the wake-up indicator detectable by the mobile station when in the dormant state; and wherein the communication system comprises a WLAN (Wireless Local Area Network) operable pursuant to operating parameters of an IEEE 802.11 operating specification that defines ADD-modify messages, and wherein the information provided to said location index is contained in an ADD-modify messase communicated by the mobile station.
