Neighbor cell notifying apparatus and neighbor cell notifying method

A neighbor cell notifying apparatus for notifying a mobile station of predetermined information in a mobile communication network for implementing radio communication utilizing a plurality of cells between the mobile station and a base station, the neighbor cell notifying apparatus comprising:

• cell information extracting means for extracting neighbor cell information items for specifying respective neighbor cells corresponding to each of said plurality of cells;
• cell rank determining means for determining ranks of neighbor cell information items that the mobile station is to be notified of, based on the neighbor cell information items extracted and on priority information items preliminarily determined for the respective neighbor cells;
• and
• cell information notifying means for notifying the mobile station of a predetermined number of neighbor cell information items among said neighbor cell information items on the basis of the ranks determined.
