Deveshkumar N Rai, Manoj Shetty, Sachin R Vargantwar, Siddharth S Oroskar, Debasish Sarkar: Method and system of paging a mobile station. Sprint Spectrum, June 19, 2012: US08204517 (10 worldwide citation)

An access network may identify paging areas based on a reference location (e.g., a mobile station's last known location), where each paging area includes at least one coverage area. The access network may then determine paging-channel occupancies for coverage areas in at least identified paging area ...
