INFORMATION COLLECTION DEVICE, COMMUNICATION FAILURE DETECTION DEVICE, AND COMPUTER PROGRAM

摘要

When a communication device is connected to another device, a signaling packet analysis unit (12) extracts a time and communication device information for identifying the communication device which transmits a signaling packet from the signaling packet to be transmitted. According to the communication information and the time extracted by the signaling packet analysis unit (12), a counting unit (13) counts the number of times the communication device transmitted the signaling packet within a predetermined time.
