1. A base station apparatus comprising:
- a memory that stores a list of coverage cells of the base station apparatus or of a predetermined base station apparatus, for each of coverage cells of the base station apparatus, the coverage cells in the list neighboring the each of coverage cells of the base station apparatus; and
a processor that extracts, from the memory, a combination of a coverage cell of a predetermined base station apparatus and a coverage cell of the base station apparatus, the coverage cell of the predetermined base station apparatus being included in a list for the coverage cell of the base station apparatus, creates a notification message including the combination, and sends the notification message to the predetermined base station apparatus.

Abstract
A first base station apparatus, when newly installed, extracts cells of a second base station apparatus and its coverage cells neighboring them from neighboring cell information stored therein. The first base station apparatus notifies the second base station apparatus of the cells by a notification message. The second base station apparatus updates neighboring cell information stored therein based on the notification message. The first base station apparatus also sends a notification message to a third base station apparatus so that the third base station apparatus updates neighboring cell information stored therein.

8. A base station apparatus comprising:
-
a memory that stores a list of coverage cells of the base station apparatus or of other base station apparatus, for each of coverage cells of the base station apparatus, the coverage cells in the list neighboring the each of coverage cells of the base station apparatus; and a processor that, upon receipt from the other base station apparatus of a notification message including a combination of a coverage cell of the other base station apparatus and a coverage cell of the base station apparatus, the coverage cell of the other base station apparatus neighboring the coverage cell of the base station apparatus, stores the combination, if not present in the memory, in the memory.

9. A neighboring cell information management method comprising:
-
a first base station apparatus storing, as first neighboring cell information, a list of coverage cells of the first base station apparatus or of a second base station apparatus, for each of first coverage cells of the first base station apparatus, the coverage cells in the list neighboring the each of first coverage cells of the first base station apparatus; a second base station apparatus storing, as second neighboring cell information, a list of coverage cells of the second base station apparatus or of the first base station apparatus, for each of second coverage cells of the second base station apparatus, the coverage cells in the list neighboring the each of second coverage cells of the second base station apparatus; the first base station apparatus extracting, from the first neighboring cell information, a combination of a second coverage cell and a first coverage cell, the second coverage cell being included in a list for the first coverage cell of the first base station apparatus; the first base station apparatus creating a notification message including the combination to send the notification message to the second base station apparatus; and the second base station apparatus storing, upon receipt of the notification message, the combination, if not present in the second neighboring cell information, to update the second neighboring cell information. - View Dependent Claims (10, 11, 12, 13, 14)
