Abstract: PROBLEM TO BE SOLVED: To efficiently process a client with the high frequency of utilization while surely providing prescribed services to all the clients. SOLUTION: The existence of data call to generate a line with the high frequency of utilization is detected by detecting a response signal (301), testing the signal of tone or the like on the node of that call later (311) and investigating whether the duration of that call exceeds prescribed time or not (315). The line for transmitting or receiving the data call exceeding the prescribed time is monitored for next measuring its frequency of utilization. As a result, the line with the high frequency of utilization can be detected by monitoring only the comparatively less lines for transmitting or receiving the data call.
