Abstract:
A method for setting a location registration zone in a code division multiple access system, said system including mobile stations and base transceiver stations, the method comprising the steps of:calculating a paging load for a mobile station in a specific test area, wherein said paging load, Lp is calculated as LP=AÃ—PS+BÃ—Pu+CÃ—RR, where A defines the amount of subscriber information per responded paging, B defines the amount of subscriber information per non-responsed paging, C defines the amount of subscriber information per response to registration, PS defines the frequency of response to paging, Pu defines the frequency of non-response to paging, and RR defines the frequency of response to registration; calculating a registration load for a mobile station in said test area; calculating the summation of said calculated paging load and registration load; and determining an optimal number of base transceiver stations required to minimize said calculated summation and setting a location registration zone corresponding to a coverage area associated with said optimal number of base station transcievers.
