Method of determining a relocation start in a mobile communication system, radio network controller having a relocation start determination function, and mobile communication system including the radio network controller
First Claim
1. A method of determining a relocation start in a mobile communication system in which each of service areas is constituted of a plurality of cells, comprising:
- determining, when a mobile station moves into a different service area, whether the service area is a relocation inhibition target or not based on prestored first data;
determining, when the service area is not a relocation inhibition target, whether a cell where the mobile station exists is a relocation inhibition target or not based on prestored second data; and
determining advisability of a start of relocation processing based on the determination results.
