First, when the client terminal CL (any one of CL-1 to CL-1) instructs the management device 300 to start the usage state totalization process, the management device 300 sends each communication carrier to the master device 100 through the network NW. A request is made to detect the usage status of the systems of companies A to M (sequence S701).

Then, control unit 290 (reporting unit 290 b ) transmits the aggregated uplink data to master device 100 via MU interface unit 210 . On the other hand, control unit 160 (aggregating unit 160a) of parent device 100 receives aggregated upstream data from child devices 200-1 to 200-n and records it in storage unit 170 as aggregated upstream data 170c.

After that, when the counting period T or longer has passed since the start of detection (sequence S703), master device 100 puts together downlink aggregated data 170b and uplink aggregated data 170c recorded in storage unit 170, and generates report data (sequence S708). ). Specifically, the control unit 160 (aggregation unit 160a) generates report data in which aggregated downlink data 170b and aggregated uplink data 170c recorded in the storage unit 170 are summarized.

Thereafter, sequences S710-714 are periodically executed. Note that the sequences S710, S711, S712, S713, and S714 are the same processing as the sequences S705, S706, S707, S708, and S709 described above, so description thereof will be omitted.

In addition, in the management apparatus 300, when report data is received by sequence S709 or sequence S714, the following processes are performed. That is, the control unit 340 of the management device 300 records the report data received through the MU interface unit 310 in the usage database 332 .

After that, for example, in response to a request from the client terminal CL-1, the report data is read from the usage status database 332, and based on this report data, the traffic volume of each telecommunications carrier A company to M company for each aggregation period T is associated with the time to create display information that visually indicates it.

Various GUIs (Graphical User Interfaces) and CLIs (Character User Interfaces) are conceivable for displaying information on the client terminals CL-1 to CL-l. FIG. 8 is an example of the above display information. In this example, the aggregate period T is set to 72 hours, and changes and ratios of traffic of each communication carrier are shown in correspondence with time. Such display information is generated by the management device 300 and provided to the client terminal CL-1, and the client terminal CL-1 displays the display information to the operator.

As described above, in the communication relay system configured as described above, the base unit 100 monitors the downlink signals sent from the base station devices BSa to BSm of the communication carriers A to M, and the downlink signals for each communication carrier are monitored. The slave units 200-1 to 200-n monitor the uplink signals sent from the mobile stations UEa to UEm that have subscribed to the services provided by the communication carriers A to M, respectively, and detect the traffic volume. The uplink traffic volume is detected for each carrier, and the parent device 100 generates report data by summing up these uplink and downlink traffic volumes for each communication carrier, and transmits the report data to the management device 300 . Therefore, according to the communication relay system configured as described above, it is possible to grasp the usage status of communication resources in the communication relay system of each communication carrier based on the report data.

It should be noted that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying constituent elements without departing from the scope of the present invention at the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiments is also conceivable. Furthermore, components described in different embodiments may be combined as appropriate.

For example, in the above embodiment, the uplink traffic volume is counted by the child devices 200-1 to 200-n, but the present invention is not limited to this. For example, the child devices 200-1 to 200-n may detect the amount of uplink traffic, notify the parent device 100, and the parent device 100 may totalize the amount.

Also, in the above embodiment, the report data is generated by the master device 100, but the present invention is not limited to this. For example, notifying the management device 300 of the amount of downlink traffic detected by the parent device, and notifying the management device 300 of the amount of uplink traffic detected by the child devices 200-1 to 200-n via the parent device 100, The control unit 340 of the management device 300 may count downlink and uplink traffic volumes.

Further, in the above embodiment, the signal detection unit 122 and the signal detection unit 270 determine the presence or absence of a communication signal in order to investigate the usage of communication resources in the base device 100 and the child device 200, and based on the determination result, It has been explained that the control unit 160 and the control unit 290 detect traffic volume from time. Instead of this, for example, the amount of data for each communication carrier may be detected.
In addition, it goes without saying that various modifications can be made in the same way without departing from the scope of the present invention.
