Abstract:
To provide a network monitoring system extracting the performance measurement data while eliminating the performance measurement data that is not effective for improvement of the network performance on the basis of a predetermined extraction condition and presenting the extraction result to the operator. The network monitoring system includes extraction condition presenting means for presenting a predetermined extraction condition indicating a relationship between performance measurement data of each device configuring the network and a status of a device to be eliminated upon extracting said performance measurement data; and performance measurement data extracting means for eliminating the performance measurement data that is measured under a status of the device to be eliminated on the basis of an extraction condition indicated by said extraction condition presenting means and extracting the performance measurement data that is effective for improvement of the network performance.

Abstract:
Concentrated use of wireless resources by location registrations carried out by slave mobile stations all together when a plurality of slave mobile stations present in a moving body provided with a master mobile station while bridging adjacent location registration areas is prevented. For this purpose, a mobile communications system 1 comprises: at least a broadcast information transmitting function unit (21) for notifying to the slave mobile stations (3) that the slave mobile stations are slaved to the master mobile station (2), a link maintaining function unit (31) for holding master-slave relationships, home location registers (5, 6) provided with expansion areas (52, 62) for holding the mobile station link information, and a mobile station link information forwarding function unit (41) for forwarding the address information of the master mobile station (2).
