Abstract:
1. A method for determining a plurality of registration areas in a wireless communication system, wherein the wireless communication system comprises a plurality of first registration areas, and each of the first registration areas comprises at least one of a plurality of first partition units, the method comprising the steps of: performing a registration area determining procedure according to a plurality of mobility data corresponding to the first partition units to determine a plurality of second registration areas, wherein each of the second registration areas comprises at least one of the first partition units; comparing an overall cost of the first registration areas with an overall cost of the second registration areas; determining a plurality of second partition units, including a dynamic partition unit, and a plurality of mobility data corresponding to the second partition units and the dynamic partition unit according to the result of comparison, wherein at least the dynamic partition unit is generated by combining at least two of the first partition units when the overall cost of the first registration areas is lower than or equal to the overall cost of the second registration areas, and at least the dynamic partition unit is generated by partitioning one of the first partition units when the overall cost of the first registration areas is higher than the overall cost of the second registration areas; and performing the registration area determining procedure according to the mobility data corresponding to the second partition units and the dynamic partition unit to determine a plurality of third registration areas, wherein each of the third registration areas comprises at least one of the second partition units, and one of the third registration areas includes the dynamic partition unit.
