Claim:
An operation data creating method for creating operation data in a mobile communication system which includes a plurality of base stations within a service area and a mobile station which makes a wireless communication with the base stations, said operation data creating method comprising the steps of: creating quality information indicating the communication quality level with respect to each base station at each of plural identified regions within a cell of the service area; selecting a subset of first identified regions from the plural identified regions, a first base station having a highest communication quality level at each identified region in the subset of first identified regions based on the created quality information, said subset of first identified regions including a local position of the mobile station; creating a list having base stations arranged at positions in an order form a highest communication quality level based on the created quality information, with respect to each identified region; selecting from each list base stations having a second highest or subsequent communication quality level which is lower than the first base station at each identified region in the subset of first identified regions where the first base station has the highest communication quality level in the corresponding list based on the created quality information; and creating the operation data indicating the selected base stations as other base stations related to the first base station having the highest communication quality level.
