Patent ID: 8478293

Claim:
A mobile station paging method, comprising: receiving a service call request and selecting a corresponding posterior probability table according to an identifier of a target mobile station included in the service call request, wherein the posterior probability table comprises distribution probability of the target mobile station in each cell of a location area where the target mobile station is located in a service state; and selecting a cell to page the target mobile station according to the distribution probability by classifying each cell in the posterior probability table into one of a plurality of paging sets by selecting a paging set comprising the minimum number of cells, where P 1 >P t1 , P 2 >P t2 , . . . , P K >P tK , where P k represents a sum of the distribution probabilities corresponding to the cells included in the first paging set to the kth paging set in the K paging sets, P tk represents a paging success probability threshold in a kth time, k and K are positive integers, 0<k≦K, and K represents the maximum paging times, wherein the paging sets are obtained in a descending order of the distribution probabilities and the maximum paging times is obtained according to the maximum allowable call delay of the service call request and each paging time; and paging the target mobile station in a descending order of the distribution probabilities with the paging set as a unit.
