Abstract
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, includes: 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.

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.
A method of determining a relocation start in a mobile communication system in which each of service areas covered by each of radio network controllers is constituted of a plurality of cells, comprising:
- determining, when a mobile station moves into a service area of an adjacent radio network controller, whether the adjacent radio network controller is a relocation inhibition target or not based on a first database;
- determining, when the adjacent radio network controller is not a relocation inhibition target, whether a cell where the mobile station exists is a relocation inhibition target or not based on a second database;
- and
- determining advisability of a start of relocation processing based on the determination results.
A method of determining a relocation start in a mobile communication system in which each of service areas covered by each of radio network controllers is constituted of a plurality of cells, wherein the radio network controller for controlling a mobile station comprises:
- a first database for storing information to determine an adjacent radio network controller of a relocation inhibition target;
- and
- a second database for storing information to determine a cell of a relocation inhibition target in a service area covered by an adjacent radio network controller, and
- wherein the method executed in the radio network controller includes determining advisability of a start of relocation processing by referring to the first and second databases when the mobile station moves into a service area covered by an adjacent radio network controller.
