Description

This invention relates to a communication monitoring device, a communication monitoring system, a communication monitoring method, and a program, and for example, to a communication monitoring device, a communication monitoring system, a communication monitoring method, and a program for monitoring the presence or absence of communication failures at a base station. During disasters such as earthquakes and typhoons, power outages to wireless base stations or transmission line failures can cause communication disruptions, including outages, in mobile communications provided by mobile carriers or third-party wireless communications using MCA (multi-channel access) wireless technology. In addition, it is anticipated that there will be a surge in requests for network connections to confirm the safety of those in disaster-stricken areas. In this case, mobile carriers implement traffic restrictions for each communication area to prevent congestion (for example, Patent Document 1).

(Communication monitoring device 10) Figure 1 is a block diagram showing the configuration of the communication monitoring device 10 according to this embodiment 1. As shown in Figure 1, the communication monitoring device 10 includes an acquisition unit 11, a monitoring unit 12, and a notification unit 13. The acquisition unit 11 acquires information indicating the received signal strength (RSSI; Received Signal Strength Indicator) of the wireless communication. The acquisition unit 11 is an example of an acquisition means. In one example, the acquisition unit 11 acquires information from the wireless communication terminal (not shown) indicating the strength of the radio signal received from the wireless base station (hereinafter abbreviated as base station 99 (Figure 5)). A wireless communication terminal is, for example, a mobile device capable of wirelessly accessing mobile broadband. The wireless communication terminal may be a USB (Universal Serial Bus) memory device, a CompactFlash® card, an SD memory device, or a mobile Wi-Fi® router. Base stations 99 are constructed by mobile carriers. At the end of the telephone network, base stations 99 communicate wirelessly with wireless communication terminals (e.g., mobile phones) within their coverage area (cell), enabling these terminals to make phone calls or access wide-area networks such as the internet. Base stations 99 can be in various forms, including tower-type, pole-type, antenna-type, and portable types. The acquisition unit 11 outputs information indicating the received signal strength of the wireless communication to the monitoring unit 12.
