  FIG. 3 is a sequence diagram showing the overall operation of the mobile communication system of the present embodiment.

  First, in the host control device 30, a communication area in which the number of in-zone subscribers should be investigated is determined as the communication area 20 (FIG. 3: step s301, survey area specifying step). Subsequently, an incoming signal in which an identifier for checking the number of subscribers is set is generated (FIG. 3: step s302, signal generation step). The generated incoming signal is transmitted to the communication area 20 all at once (FIG. 3: step s303, identifier transmission step). Thereby, the identifier for investigation can be instantaneously transmitted to all mobile terminals located in the communication area 20 at this time.

  Then, the mobile terminal 40, 41, 42 located in the communication area 20 receives the incoming signal (FIG. 3: step s401, incoming signal reception process), and an identifier for checking the number of subscribers is included in this incoming signal. It is determined whether it is set (FIG. 3: step s402, identification poem detection step). As a result, a signal unrelated to the subscriber survey can be repelled, and a more accurate survey is possible.

  When it is determined that the investigation identifier is set in the incoming signal, a response signal with a specific code is returned (FIG. 3: step s403, response signal return step). Then, the host control device 30 determines whether or not the received signal is a response signal to the investigation identifier from the mobile terminal (FIG. 3: step s305, response signal detection step). Is counted and stored (FIG. 3: step s306, response number storage step).

  Thus, by counting the number of response signals from the mobile terminals 40, 41, and 42, the number of subscribers residing in the communication area 20 at that time can be grasped instantaneously.

  Here, the contents of the identifier transmission process, response signal detection process, and response count storage process described above are programmed and executed by a computer that controls the RNC as an identifier transmission process, a response signal detection process, and a response count storage process.

  In this embodiment, the RNC as the host control device includes the incoming signal generation means 302, the survey area specifying means 303, and the identifier transmission means 304, determines the communication area 20 in which the number of in-zone subscribers should be investigated, The communication area 20 functions to broadcast an incoming signal in which an identifier for the number of subscribers survey is set. However, the present invention is not limited to this, and the MSC or SGSN as the overall control device 31 generates an incoming signal. The means 302, the survey area specifying means 303, and the identifier transmitting means 304 may be mounted so that the incoming signal in which the identifier for the number of subscribers survey is set is transmitted simultaneously.

  In this way, since the device that generates and broadcasts the incoming signal and the device that receives and counts the response signal are separated into different devices, the processing burden for each device is reduced, and the processing capacity of the subscriber number survey is reduced. improves.
