Abstract

It administers a plurality of wireless base stations grouped into a plurality of groups, and performs the processing about the management, control and maintenance of the wireless base stations selectively for each of the groups. This enables the efficient management, control and maintenance processing of the wireless base stations.

Claims

1. A wireless communication system, comprising:

a plurality of wireless base stations,

an apparatus for management, control, and maintenance that groups the wireless base stations into a plurality of groups and performs processing about management, control and maintenance of the wireless base stations selectively for each of the groups.

2. A method of management, control, and maintenance, the method comprising:

controlling a plurality of wireless base stations grouped into a plurality of groups, and

performing processing about management, control and maintenance of the wireless base stations selectively for each of the groups.

3. An apparatus for management, control, and maintenance, the apparatus comprising:

a control unit that administers a plurality of wireless base stations grouped into a plurality of groups, and

a processor that performs processing about management, control and maintenance of the wireless base stations selectively for each of the groups.

4. The apparatus for management, control, and maintenance according to claim 3, wherein

the control unit stores threshold about a number of failures of the wireless base stations for each of the groups, and

the processor monitors event of a failure in the wireless base stations, and determine that a failure has occurred in one of the groups when the number of failures in the group is equal to the threshold or more.

5. The apparatus for management, control, and maintenance according to claim 4, wherein the processor determines that no failure has occurred in the group of the wireless base stations when the number of failures is less than the threshold in the group.

6. The apparatus for management, control, and maintenance according to claim 4, wherein the processor notifies failure information to an upper apparatus of the apparatus for management, control, and maintenance when it is determined that a failure has occurred in the group.

7. The apparatus for management, control, and maintenance according to claim 4, wherein the processor monitors the event of a failure by receiving the failure information from each of the wireless base stations.

8. The apparatus for management, control, and maintenance according to claim 4, wherein the processor monitors the event of a failure also in the apparatus for management, control, and maintenance and notifies the monitoring result to the upper apparatus of the apparatus for management, control, and maintenance.

9. The apparatus for management, control, and maintenance according to claim 3, wherein

the control unit stores threshold about congestion of the wireless base stations for each of the groups, and

the processor monitors congestions of the wireless base stations and determines that congestion has occurred in one of the groups when the congestion in the group is equal to the threshold or more.

10. The apparatus for management, control, and maintenance according to claim 9, wherein the processor determines that no congestion has occurred in a group when the congestion in the group is less than the threshold.

11. The apparatus for management, control, and maintenance according to claim 9, wherein, when it is determined that congestion has occurred in a group, the processor notifies the upper apparatus of the apparatus for management, control, and maintenance of the determination.

12. The apparatus for management, control, and maintenance according to claim 9, wherein the processor monitors the congestion by receiving notification of congestions detected by each of the wireless base stations.

13. The apparatus for management, control, and maintenance according to claim 9, wherein the processor monitors the congestion by receiving notification of a communication traffic amount measured by each of the wireless base stations.

14. The apparatus for management, control, and maintenance according to claim 9, wherein the processor monitors the congestion of the apparatus for management, control, and maintenance and notifies the monitoring result to the upper apparatus of the apparatus for management, control, and maintenance.

15. The apparatus for management, control, and maintenance according to claim 9, wherein the processor controls calls in each of the wireless base stations belonging to a group determined to have the congestion.

16. The apparatus for management, control, and maintenance according to claim 3, wherein

the control unit stores threshold about an update rate of a file stored by the wireless base stations for each of the groups, and

the processor monitors the update rate of the file stored by the respective wireless base stations, and updates the file of each of the wireless base stations belonging to one of the groups when the update rate in the group exceeds the threshold.

17. The apparatus for management, control, and maintenance according to claim 16, wherein the processor determines that update of the file is not necessary when the update status is equal to the threshold or less.

18. The apparatus for management, control and maintenance, according to claim 16, wherein the processor notifies information about the update rate exceeding the threshold of the update rate to the upper apparatus of the apparatus for management, control, and maintenance.

19. The apparatus for management, control, and maintenance according to claim 3, wherein the wireless base station is a femtocell station.

20. The apparatus for management, control, and maintenance according to claim 3, wherein the group is set depending on a setting place of the wireless base station.
