Mobile station paging method and mobile call center device

A mobile call center device, comprising:

• a first processing module, configured to receive a service call request and to select 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
• a paging module, configured to select a cell to page the target mobile station according to the distribution probability, the paging module comprising:
• a first processing sub-module, configured to classify each cell in the posterior probability table into one of plurality of paging sets by selecting a paging set comprising the minimum number of cells, where P1>Pt1, P2>Pt2, . . . , PK>PtK, where Pk 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, Ptk represents a paging success probability threshold in a kth 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
• a second processing sub-module, configured to page the target mobile station in a descending order of the distribution probabilities with the paging set as a unit.
