  The icon 91 is, for example, an icon dedicated to the switching operation. That is, when the user performs an operation on the icon 91, the connection application is activated independently.

  Note that in the wireless terminal device 202, a connection application-linked icon may be displayed for each application. That is, when the user performs an operation on the icon 91, the connection application and other applications are activated.

  When such an icon is used, for example, the wireless terminal device 202 is provided with a separate screen for displaying a normal application icon and a screen for collectively displaying connection application-linked icons. In addition, a launcher capable of displaying a list of a plurality of applications and selecting activation may be used.

  Note that the wireless terminal device 202 is not limited to the configuration in which the switching operation is started when the user performs an operation on the connection application icon. For example, the wireless terminal device 202 is configured to be able to start the connection application with the user's voice. Also good.

  FIG. 7 is a diagram showing an example of a setting screen of the wireless terminal device according to the embodiment of the present invention.

  Referring to FIG. 7, the method is not limited to a method in which the user instructs radio terminal apparatus 202 to switch the communication partner to small base station 101 by operating icon 91. Further, the configuration is not limited to a configuration in which the user instructs the wireless terminal device 202 to perform a switching operation using a connection application.

  For example, as indicated by a dotted circle, by directly changing the carrier selection to “SmallCell” on the setting screen, the user can instruct the wireless terminal device 202 to perform the switching.

  FIG. 8 is a diagram illustrating an example of a monitoring operation performed by the radio base station apparatus according to the embodiment of the present invention.

  Referring to FIG. 8, since it is not possible to accurately control the distance that radio waves from small base station 101 propagate, small base station 101 analyzes radio wave echoes, that is, reflected waves, similarly to radar. Thus, the monitoring operation is performed.

  For example, in the small base station 101, the detection unit 36 further measures the distance between the person and the own small base station 101 in the target area based on the radio wave received by the LTE communication unit 31 or the WiFi communication unit 32. .

  That is, even if a person is detected, if the distance to the small base station 101 is not known, it is not possible to determine, for example, whether a person has entered the store or simply passed through the store. The distance determination using the reflected wave is performed. Thereby, the small base station 101 detects a person using the reflected wave, and determines whether or not the detected person exists in the target area. The small base station 101 can determine that there is a person at a position on the circumference of a circle whose radius is the measurement distance with the self as a center.

  Specifically, when the time from when the detection radio wave 151 is transmitted from the small base station 101A installed in the store to when the reflected wave 152 is received at the small base station 101 is 0.1 microseconds, The propagation distance of is 30 m and 15 m one way. Assuming that this 15 m is the size from the small base station 101A to the boundary of the store, the small base station 101A will return to the small base station 101A if the reflected wave 152 returns to the small base station 101A within 0.1 microsecond. It is determined that has entered, and an alarm is output. On the other hand, if the time for the reflected wave 152 to return to the small base station 101A is longer than 0.1 microsecond, the small base station 101A determines that there is only a person outdoors or in the passage, and issues a warning. Absent.

  Since the inside of the store and the area shape are complicated, it is possible to improve the accuracy of determining whether a person has entered the target area by installing a learning function in the small base station 101.

  In addition, when the communication system 301 includes a plurality of small base stations 101, the plurality of small base stations 101 can perform a monitoring operation in cooperation with each other to increase the level of the crime prevention service.

  That is, in the small base station 101, the reporting unit 38 transmits information indicating the distance measured by the detecting unit 36 to the network via the mobile communication network transmitting / receiving unit 41 or the IP network transmitting / receiving unit 42.

  Specifically, for example, each of the small base station 101A and the small base stations 101B and 101C installed outside the store determines the distance between the detected person and itself based on the reflected wave 152 of the detection radio wave 151. Measure and notify the measured distance to the server in the network. Then, the server performs three-point measurement using the distance notified from each small base station 101, and calculates the coordinates of the intruder.

  Thus, the structure which performs a complex measurement can improve the intruder detection accuracy and the intruder location specifying accuracy.

  Here, the small base station 101 can switch between the normal mode and the monitoring mode as the operation mode. The detection unit 36 performs a monitoring operation in the monitoring mode.

  Specifically, for example, when the store clerk performs a mode switching operation when the store is closed, the small base station 101 shifts to the monitoring mode.

  Alternatively, the small base station 101 automatically shifts to the monitoring mode when the number of people in the store decreases, specifically, for example, when the amount of communication with the wireless terminal device 202 decreases. Alternatively, the small base station 101 creates a delay profile of the reflected wave of its own transmission radio wave, and operates in the normal mode because there are many people in the store when the radio wave state indicated by the delay profile fluctuates. When the radio wave state indicated by the delay profile is not changed, the monitor mode is entered.

  As described above, in the monitoring mode, it may be possible to perform a communication operation with the wireless terminal device 202 similar to the normal mode, or a configuration in which only the monitoring operation is performed. In the former case, the small base station 101 performs a monitoring operation for detecting a person in the target area based on the received radio wave while performing wireless communication as necessary.

  FIG. 9 is a flowchart defining an operation procedure when the small base station in the communication system according to the embodiment of the present invention monitors the target area using the reflected wave.

  Referring to FIG. 9, when the small base station 101 is operating in the normal mode (step S21), when switching to the monitoring mode occurs (YES in step S22), the small base station 101 transmits a detection radio wave to the target area. (Step S23).

  Next, the small base station 101 receives the reflected wave from the target area (step S24), and performs a monitoring operation based on the received reflected wave (step S25).

  Next, when the small base station 101 does not detect a person in the target area (NO in step S25), the small base station 101 repeats transmission of the detection radio wave and reception of the reflected wave (steps S23 to S25).

  On the other hand, when the small base station 101 detects a person in the target area (YES in step S25), the small base station 101 outputs an alarm (step S26).

  Next, the small base station 101 further measures the distance between itself and the intruder using the received reflected wave (step S27).

  Next, the small base station 101 notifies the server in the network that the intruder has been detected and the measured distance (step S28).

  The small base station 101 may be configured to perform either one of alarm output (step S26) and notification to the server (step S28).

  FIG. 10 is a diagram illustrating an example of a monitoring operation performed by the radio base station device according to the embodiment of the present invention.

  Referring to FIG. 10, when store goods are stolen by a plurality of offenders, there is a high possibility that an intruder into the store and a watcher outside the store communicate with each other using a mobile phone. Therefore, the small base station 101 performs a monitoring operation by analyzing communication radio waves transmitted or received between itself or another radio base station apparatus.

  Specifically, at night, it is possible to acquire the travel route of the intruder by recording the communication history of the wireless terminal device 202 for crime prevention. The communication history may be, for example, a history of handover operation of the wireless terminal device 202 or a history of intercepting communication radio waves.

  For example, in the small base station 101, the communication history acquisition unit 37 includes information on the time when the wireless terminal device 202 communicated with its own small base station 101 or another wireless base station device, and its own small base station 101 or other A communication history that is at least one of the measurement results related to the wireless terminal device 202 communicating with the wireless base station device is acquired. Note that the information related to time may be, for example, an absolute time such as a time, a relative time, or a length of a period.

  Specifically, the small base station 101A installed in the store uses radio terminals transmitted or received by the wireless terminal device 202 in order for an intruder in the store to contact a watcher outside the store, that is, a wireless terminal The apparatus 202 receives the communication radio wave 153 transmitted or received with, for example, the macro base station 131 or the small base station 101B outside the store, and detects an intruder in the store using the received communication radio wave 153 To do.

  The small base station 101 may be configured to measure the distance between a detected person and the small base station 101 using a communication radio wave.

  The small base station 101 can perform a monitoring operation using radio waves such as Zigbee (registered trademark) and wireless LAN as communication radio waves, not limited to mobile phones.

  In addition, when the communication system 301 includes a plurality of small base stations 101, the plurality of small base stations 101 can perform a monitoring operation in cooperation with each other to increase the level of the crime prevention service.

  That is, in the small base station 101, the reporting unit 38 transmits information indicating the communication history acquired by the communication history acquiring unit 37 to the network via the mobile communication network transmitting / receiving unit 41 or the IP network transmitting / receiving unit 42.

  Specifically, each of the small base station 101A and the small base stations 101B and 101C installed outside the store transmits the communication history of the wireless terminal device 202 to the server. Then, the server calculates, for example, an intruder's movement route using the communication history received from each small base station 101.

  Thus, the structure which performs a complex measurement can improve the intruder detection accuracy and the intruder location specifying accuracy.

  Next, when receiving the communication radio wave (YES in step S33), the small base station 101 analyzes the received communication radio wave and records the communication history of the wireless terminal device 202 (step S34).

  Next, the small base station 101 analyzes the received communication radio wave and performs a monitoring operation based on the analysis result (step S35).

  Next, when the small base station 101 does not detect a person in the target area (NO in step S35), the small base station 101 repeats reception of communication radio waves and recording of a communication history (steps S33 to S35).

  On the other hand, when the small base station 101 detects a person in the target area (YES in step S35), the small base station 101 outputs an alarm (step S36).

  Next, the small base station 101 notifies the server in the network of the detected intruder and the recorded communication history (step S37).

  The small base station 101 may be configured to perform either one of alarm output (step S36) and notification to the server (step S37).

  In addition, the small base station 101 is not limited to the configuration in which the recorded communication history is collectively transmitted to the server when a person is detected in the target area, and the wireless terminal device can be used even when the person in the target area is not detected. The configuration may be such that every time a communication history of 202 is obtained, it is transmitted to the server.

  The small base station 101 may be configured to perform either one of the monitoring operation using the reflected wave and the monitoring operation using the communication radio wave, or may be configured to perform these monitoring operations in parallel. May be.
