Description

  The present invention relates to a technique for performing processing according to the ability of a relay device that amplifies and transmits a radio signal from a base station to transmit the radio signal.

  In order to improve the reception environment for radio signals (radio waves) from a base station, a relay device called a repeater may be used. This relay device amplifies and transmits a radio signal received from the base station. When the capability (efficacy) of transmitting a radio signal of such a relay device is reduced, for example, when an abnormality such as a failure occurs in the relay device, the user may not be able to use the wireless communication service. Moreover, in stores, such as a restaurant, the customer who visited the store becomes a user of a wireless communication service. In this case, it is difficult for the user to notice the abnormality of the relay device. For this reason, even if an abnormality occurs in the relay device, the abnormality may be buried without being noticed by anyone.

  If it is quickly identified that the cause is an abnormality of the relay device, the user's inconvenience is reduced. However, it is not easy for a telecommunications carrier to quickly grasp such an abnormality. Although there is a method of regularly performing maintenance of relay devices, when the number of relay devices that circulate increases, the work load related to the maintenance increases.

  On the other hand, in Patent Document 1, in a repeater, the presence or absence of a failure in the amplification system is determined based on the difference between the level of the signal amplified in the amplification system and the level of the signal not amplified in the amplification system. It is described. In Patent Document 2, a radio base station diagnoses the presence or absence of a control abnormality in its amplifier in accordance with a remote operation command from a host monitoring device connected via a communication line, and transmits the diagnosis result to the host monitoring device. It is described. According to the techniques described in Patent Documents 1 and 2, an artificial work load is reduced. Patent Document 3 describes that a repeater acquires a cell ID for identifying a radio base station to which the repeater belongs and notifies the maintenance service center station of the cell ID.

The techniques described in Patent Documents 1 and 2 do not monitor the wireless signal that is actually transmitted by the relay device. The technique described in Patent Document 3 cannot automatically detect a failure of a repeater. As described above, in the techniques described in Patent Documents 1 to 3, the ability of relay devices to transmit radio signals cannot be grasped with a reduced burden on human work.
On the other hand, an object of this invention is to enable it to perform the process according to the capability which transmits the radio signal of a relay apparatus, without increasing an artificial work.

A position where the environment is good or bad may be determined.
Further, the processing unit may determine that the reception environment is bad when a difference between the first level and the second level is equal to or less than a fourth threshold value. Alternatively, the processing unit may determine that the reception environment is bad when the first level is equal to or less than a fifth threshold.

[Summary of Invention]
The information processing system of the present invention is a system that executes processing according to the ability of a relay device to transmit a radio signal (hereinafter sometimes referred to as “capability of the relay device”). In the embodiment described below, the capability is grasped by the level of the radio signal transmitted by the relay device. In the repeater maintenance system of the first embodiment, the ability to change according to the presence or absence of an abnormality of the repeater is grasped. In the reception environment management system of the second embodiment, the ability of the repeater to change according to the reception environment of the radio signal from the base station is grasped.

[First Embodiment]
<Configuration>
FIG. 1 is a diagram showing an overall configuration of a repeater maintenance system 1 according to the first embodiment. The repeater maintenance system 1 is a system that supports the maintenance of a repeater. The repeater maintenance system 1 includes one host device 10, a plurality of monitoring devices 20, a plurality of repeaters 30, and a computer device 40. However, the number of these devices is only an example. In FIG. 1, only base stations BS1, BS2, BS3 are shown as base stations connected to the communication line NW, but there are actually more base stations. When there is no need to distinguish each of the base stations, they are collectively referred to as “base station BS”.

  The host device 10 collects data for grasping the capabilities of each of the plurality of repeaters 30. Then, the host device 10 determines whether each of the plurality of repeaters 30 is abnormal. The host device 10 is managed by, for example, a communication carrier that lends or transfers the repeater 30 to a user. The host device 10 corresponds to the information processing device of the present invention.

The monitoring device 20 monitors the repeater 30 based on the radio signal received from the repeater 30. One monitoring device 20 monitors one repeater 30. For example, the monitoring device 20 is disposed in the user's home together with the repeater 30. The monitoring device 20 is connected to the commercial power source PS by wire using the power line C1, and is connected to the repeater 30 by wire using the power line C2. The monitoring device 20 is supplied with power from the commercial power source PS via the power line C1. The monitoring device 20 supplies power to the repeater 30 via the power line C2.
It is desirable that the connection between the monitoring device 20 and the repeater 30 via the power line C2 is a connection that cannot be easily removed by the user. The reason for this is to ensure that the monitoring device 20 is arranged at a position for receiving a radio signal from the repeater 30 to be monitored.

  The repeater 30 receives a radio signal from the base station BS, amplifies the received radio signal, and transmits it. The repeater 30 further receives a radio signal from the radio communication terminal 50, amplifies the received radio signal, and transmits it to the base station BS. That is, the repeater 30 corresponds to a relay device that relays communication performed between the base station BS and the wireless communication terminal 50. The repeater 30 receives supply of power from the monitoring device 20 via the power line C2. The radio communication terminal 50 is a communication terminal that performs radio communication via the base station BS. The wireless communication terminal 50 is, for example, a smartphone, but may be other communication terminals.

  The computer device 40 is used by a person in charge of maintenance of the repeater 30. The computer device 40 is, for example, a personal computer, but may be a computer device such as a smartphone or a tablet terminal.

  Each of the host device 10, the plurality of monitoring devices 20, the plurality of repeaters 30, the computer device 40, and the wireless communication terminal 50 performs communication via the communication line NW. The communication line NW includes, for example, a wireless communication network and the Internet, but the line type is not particularly limited.

FIG. 2 is a block diagram showing the configuration of each device of the repeater maintenance system 1.
The host device 10 includes a communication unit 11, a control unit 12, and a storage unit 13. The communication unit 11 communicates by connecting to the communication line NW. The communication unit 11 includes a modem, for example. The control unit 12 controls each unit of the host device 10. The control unit 12 includes, for example, a processor and a memory. The processor reads the program into the memory and executes it. The storage unit 13 stores data. The storage unit 13 includes, for example, a hard disk device.

  The control unit 12 includes a command generation unit 121, an acquisition unit 122, and a processing unit 123. The command generation unit 121 generates a command that instructs each of the plurality of monitoring devices 20 to execute processing. The command generation unit 121 transmits the generated command to the monitoring device 20 via the communication unit 11. The acquisition unit 122 acquires data received from the monitoring device 20 by the communication unit 11. The processing unit 123 performs processing according to the capability of the repeater 30 based on the data acquired by the acquisition unit 122. In the present embodiment, this process is a process for notifying the computer device 40 of the fact that it is determined that the repeater 30 is abnormal.

  The monitoring device 20 includes an antenna 21, a communication unit 22, a control unit 23, and a power management unit 24. The antenna 21 is an antenna for receiving a radio signal transmitted from the repeater 30. In the antenna 21, the transmitting antenna and the receiving antenna may be separated. The communication unit 22 performs communication via the communication line NW using the antenna 21. This corresponds to a receiving unit that receives radio signals from the communication unit 22 and the repeater 30. The communication unit 22 includes a communication circuit for performing wireless communication, for example. The control unit 23 controls each unit of the monitoring device 20. The control unit 23 includes, for example, a processor and a memory. The processor reads the program into the memory and executes it.

The power management unit 24 manages power supplied from the commercial power source PS. The power management unit 24 manages the supply of power in the monitoring device 20 and the supply of power to the repeater 30. The power management unit 24 includes a supply unit 241 and a switching unit 242. The supply unit 241 supplies the power supplied from the commercial power source PS to the repeater 30. The supply unit 241 includes a power supply circuit including a protection circuit and a switch circuit, for example, and supplies power to the repeater 30 when the switch circuit is on, and does not supply power to the repeater 30 when the switch circuit is off. The switching unit 242 controls the supply unit 241 to switch the state of the repeater 30. Specifically, the switching unit 242 switches the repeater 30 between an energized state in which the repeater 30 is energized and a non-energized state in which the repeater 30 is deenergized. The repeater 30 transmits the amplified radio signal in the energized state, but stops the transmission in the non-energized state. That is, the energized state corresponds to the first state of the present invention, and the non-energized state corresponds to the second state of the present invention. The switching unit 242 is configured by, for example, a processor including a CPU and a memory, and switches the switching circuit of the supply unit 241 between on and off.
Note that the control unit 23 may have a function corresponding to the switching unit 242 instead of the power management unit 24.

  The control unit 23 includes a measurement unit 231 and an output unit 232. The measurement unit 231 measures the level of the radio signal according to the command generated by the command generation unit 121. In the following description, the term “level” is a general term for a reception level and a quality level unless otherwise specified. The reception level is an index value of the strength of the received radio signal, and is, for example, the received electric field strength. The quality level is an index value of the quality of the received radio signal, and is, for example, a signal-noise ratio (SNR). The output unit 232 outputs data corresponding to the level measured by the measurement unit 231. In the present embodiment, the output unit 232 transmits the level measured by the measurement unit 231 to the host device 10 via the communication unit 22 and the antenna 21.

<Operation>
3 and 4 are sequence diagrams showing processing executed by the repeater maintenance system 1. FIG. In the repeater maintenance system 1, it is assumed that processing described below is performed for each of a plurality of monitoring devices 20.
The power management unit 24 of the monitoring device 20 puts the repeater 30 in an energized state in which power from the commercial power source PS is supplied in advance (step S1). In this case, the repeater 30 amplifies and transmits a radio signal from the base station BS.

  In the host device 10, the command generation unit 121 determines whether it is the monitoring timing for monitoring the repeater 30 (step S2). The monitoring timing may be determined in any way, but is, for example, a regular timing at which maintenance is performed. If “NO” is determined in the step S2, the process for the corresponding monitoring device 20 is ended.

  When it determines with "YES" at step S2, the command production | generation part 121 produces | generates a 1st command (step S3). The first command is a command for instructing measurement of the level of the radio signal when the repeater 30 is in the energized state. The command generation unit 121 transmits a wireless signal indicating the first command to the monitoring device 20 via the communication unit 11 (step S4).

  In the monitoring device 20, the communication unit 22 receives a radio signal indicating the first command via the antenna 21. The measuring unit 231 measures the reception level RL1 and the quality level QL1 of the radio signal according to the first command (Steps S5 and S6). In the energized state, the level measured by the measurement unit 231 (corresponding to the first level of the present invention) is when a radio signal amplified by the repeater 30 and a radio signal directly received from the base station BS are received. Indicates the level.

  The output unit 232 transmits the reception level RL1, the quality level QL1, and the device ID and the base station ID to the host device 10 via the communication unit 22 and the antenna 21 (step S7). The device ID is an identifier that uniquely identifies the monitoring device 20. The base station ID is an identifier that uniquely identifies the base station BS to which the monitoring device 20 is connected.

  In the host device 10, when the data transmitted from the output unit 232 is received by the communication unit 11, the acquisition unit 122 acquires this data (step S8). Next, the command generation unit 121 determines whether or not the reception level RL1 or the quality level QL1 is equal to or lower than the second threshold (step S9). The second threshold for the reception level and the second threshold for the quality level are predetermined values. When the reception level RL1 is less than or equal to the second threshold value, the strength of the radio signal transmitted by the repeater 30 is low, and there is a possibility that an abnormality has occurred in the repeater 30. When the quality level QL1 is less than or equal to the second threshold value, the quality of the radio signal transmitted by the repeater 30 is not good, and there is a possibility that an abnormality has occurred in the repeater 30. As described above, the level measurement according to the first command is performed for the purpose of extracting the repeater 30 in which an abnormality may occur.

If “NO” is determined in the step S9, the process for the corresponding monitoring device 20 is ended. This is because there is a low possibility that an abnormality has occurred in the repeater 30.
On the other hand, when it determines with "YES" at step S9, the command production | generation part 121 produces | generates a 2nd command (step S10). The second command is a command for instructing measurement of the capability of the repeater 30. The second command includes an instruction to set the repeater 30 to either the energized state or the non-energized state, and an instruction to measure the level of the radio signal in each state. The command generation unit 121 transmits a wireless signal indicating the second command to the monitoring device 20 via the communication unit 11 (step S11).

  In the monitoring device 20, the communication unit 22 receives a radio signal indicating the second command via the antenna 21. The measuring unit 231 measures the reception level RL2 and the quality level QL2 of the radio signal according to the second command (Steps S12 and S13). The reception level RL2 and the quality level QL2 are levels of radio signals received when the power is on.

  Next, the measurement part 231 controls the power supply management part 24, and switches the repeater 30 to a non-energized state (step S14). Thereby, repeater 30 stops transmission of a radio signal.

Next, the measurement unit 231 measures the radio signal reception level RL3 and the quality level QL3 (steps S15 and S16). The reception level RL3 and the quality level QL3 are the levels of the radio signal received in the non-energized state. In the non-energized state, the level measured by the measurement unit 231 (corresponding to the second level of the present invention) is the level of the radio signal that has reached directly from the base station BS. This level is not affected by the ability of the repeater 30.
In addition, the measurement part 231 may switch the repeater 30 to an energized state by controlling the power supply management part 24 after the process of step S16. As a result, the repeater 30 resumes the operation of amplifying and transmitting the radio signal from the base station BS.

  The output unit 232 transmits the reception level RL2, the quality level QL2, the reception level RL3, the quality level QL3, and the device ID and the base station ID to the host device 10 via the communication unit 22 and the antenna 21. (Step S17).

  In the host device 10, when the data transmitted from the output unit 232 is received by the communication unit 11, the acquisition unit 122 acquires this data (step S18). Next, the processing unit 123 calculates a level difference ΔR23 that is a difference between the reception level RL2 and the reception level RL3 (step S19). Next, the processing unit 123 calculates a level difference ΔQ23 that is a difference between the quality level QL2 and the quality level QL3 (step S20). Then, the processing unit 123 determines whether or not the level difference ΔR23 or the level difference ΔQ23 is equal to or smaller than the first threshold (step S21). The first threshold value for each level difference is a predetermined value.

FIG. 5 is a diagram for explaining abnormality determination in the host device 10.
The reception level RL3 substantially indicates the reception level of the radio signal when the repeater 30 is not present. On the other hand, if the reception level RL2 is sufficiently higher than the reception level RL3, it can be said that the reception level has been raised by the repeater 30. Therefore, as shown in the diagram on the left side of FIG. 5, when the level difference ΔR23 exceeds the first threshold value TH1, it is possible to estimate that the repeater 30 has high capability and the repeater 30 has no abnormality. On the other hand, as shown in the diagram on the right side of FIG. 5, when the level difference ΔR23 is equal to or smaller than the first threshold value TH1, it indicates that the reception level to be raised by the repeater 30 is low. In this case, the capability of the repeater 30 is not sufficiently exhibited, and there is a possibility that an abnormality has occurred in the repeater 30.

  The same can be said from the viewpoint of quality level. That is, when the quality level QL2 is sufficiently higher than the quality level QL3, it can be said that the quality level is raised by the repeater 30 and the radio wave quality is improved. Therefore, as shown in the diagram on the left side of FIG. 5, when the level difference ΔQ23 exceeds the first threshold value TH2, it is possible to estimate that the repeater 30 has high capability and the repeater 30 has no abnormality. On the other hand, as shown in the diagram on the right side of FIG. 5, when the level difference ΔQ23 is equal to or smaller than the first threshold value TH2, it indicates that the quality level to be improved by the repeater 30 is small. In this case, the capability of the repeater 30 is not sufficiently exhibited, and there is a possibility that an abnormality has occurred in the repeater 30.

  For the reasons described above, when it is determined “YES” in step S21, the processing unit 123 performs a notification process (step S22). The notification process is a process for notifying the computer device 40 that there is an abnormality in the repeater 30. In the notification process, the processing unit 123 notifies the computer device 40 that the repeater 30 indicated by the device ID is abnormal and that the repeater 30 is under the base station BS indicated by the base station ID. The person in charge who uses the computer device 40 looks at the notified contents, visits the place where the repeater 30 is arranged, and performs maintenance thereof.

  On the other hand, when the processing unit 123 determines “NO” in step S21, it is determined that there is no abnormality in the repeater 30, and the process for the corresponding monitoring device 20 is ended.

  In the repeater maintenance system 1 according to the first embodiment described above, the host device 10 controls the monitoring device 20 and the repeater 30 by remote operation, and collects data for grasping the capabilities of each of the plurality of repeaters 30. To do. Then, the host device 10 determines whether there is an abnormality in the repeater 30 based on the capability of the repeater 30 grasped from the collected data. Therefore, since the person in charge of maintenance can determine the presence or absence of the abnormality without actually inspecting the monitoring device 20, an artificial work load related to maintenance is reduced. Further, the repeater maintenance system 1 measures the level of the radio signal in two stages, that is, measurement by the first command and measurement by the second command. As a result, an increase in the load on the communication line NW and an increase in processing related to the abnormality determination are suppressed as compared with a case where measurement by the second command is performed on all the monitoring devices 20. In addition, the monitoring device 20 switches the presence / absence of transmission of a radio signal by the repeater 30 by controlling on / off of power supply to the repeater 30. Therefore, the control for such switching is simple. Further, the repeater 30 may not have a specific function for grasping the capability of the repeater 30. Therefore, an off-the-shelf repeater can be used for the repeater 30.

[Second Embodiment]
In the second embodiment of the present invention, the information processing system of the present invention is applied to a reception environment management system. The reception environment management system is different from the first embodiment described above in that the capability of the repeater is used to determine whether the reception environment of the radio signal from the base station is good or bad. The reception environment of the radio signal is grasped by the level of the radio signal. In the following description, the same elements as those of the first embodiment described above are denoted by the same reference numerals, and description thereof will be omitted as appropriate. Also. Elements corresponding to the elements of the first embodiment described above are represented by adding “A” to the end of the reference numerals.

FIG. 6 is a diagram for explaining the outline of the reception environment management system according to this embodiment.
In the area where the base stations BS1, BS2, and BS3 shown in FIG. 6 exist, the cell T1 is formed by the base station BS1, the cell T2 is formed by the base station BS2, and the cell T3 is formed by the base station BS3. . In this case, at a point close to any of the base stations BS1, BS2 and BS3, the strength and quality of the radio signal are usually high and the reception environment is good. On the other hand, in the area AR that is far from any of the base stations BS1, BS2, and BS3, the strength and quality of the radio signal may be low, and the reception environment may be poor. In the area AR, it is considered that there are many repeaters 30 as in the position P shown in FIG. Furthermore, even if the repeater 30 is used in the area AR, there is a possibility that the reception environment of the radio signal is not sufficiently improved. The reason is that if the strength of the radio signals from all of the base stations BS1, BS2 and BS3 is quite low, even if the repeater 30 amplifies the received radio signal, the repeater 30 does not reach a sufficient strength, and the quality is sufficient. It is because it does not improve. In such a case, it is difficult to improve the reception environment using the repeater 30, and it is necessary to take measures such as resetting the parameters (for example, the radiation angle) of the base station and newly installing the base station.

  Therefore, in the reception environment management system of the present embodiment, a position where the reception environment of the radio signal is bad is specified based on the point where the repeater 30 that does not sufficiently exhibit the capability exists.

<Configuration>
FIG. 7 is a block diagram showing the configuration of each device of the reception environment management system 1A. The host device 10 </ b> A includes a communication unit 11, a control unit 12, and a storage unit 13. The control unit 12 includes a command generation unit 121A, an acquisition unit 122A, and a processing unit 123A. The command generation unit 121A generates a command that instructs each of the plurality of monitoring devices 20A to execute processing. The command generation unit 121A transmits the generated command to the monitoring device 20A via the communication unit 11. The acquiring unit 122A acquires data transmitted from the monitoring device 20A in response to this command. The processing unit 123A performs processing related to the capability of the repeater 30 based on the data acquired by the acquisition unit 122A. In the present embodiment, this process is a process of notifying the computer device 40 of an area where the radio signal reception environment is not good.

The monitoring device 20A includes an antenna 21, a communication unit 22, a control unit 23, a power management unit 24, and a positioning unit 25. The positioning unit 25 performs a positioning process for measuring the position of the monitoring device 20A. The positioning process is a process for generating position information indicating the position of the monitoring device 20A. For the positioning processing, for example, a GPS (Global Positioning System) method is adopted, but other methods such as base station positioning may be adopted.
Since the monitoring device 20A and the repeater 30 are connected via the power supply line C2, the position of the monitoring device 20A may be regarded as the same as the position of the repeater 30.

<Operation>
8 and 9 are sequence diagrams showing processing executed in the reception environment management system 1A.
The power management unit 24 of the monitoring device 20A sets the repeater 30 in an energized state in which power from the commercial power source PS is supplied to the repeater 30 in advance (step S31). In this case, the repeater 30 amplifies and transmits the radio signal received from the base station BS.

  In the host device 10A, the command generation unit 121A determines whether it is the monitoring timing for monitoring the repeater 30 (step S32). The monitoring timing may be determined in any way. If “NO” is determined in the step S32, the process for the corresponding monitoring device 20A ends.

  When determining “YES” in Step S32, the command generating unit 121A generates a third command (Step S33). The third command is a command for instructing measurement of the capability of the repeater 30. The third command includes an instruction to set the repeater 30 to either the energized state or the non-energized state, and an instruction to measure the level of the radio signal in each state. The command generation unit 121A transmits a wireless signal indicating the third command to the monitoring device 20A via the communication unit 11 (step S34).

  In the monitoring device 20 </ b> A, the communication unit 22 receives a wireless signal indicating the third command via the antenna 21. The measurement unit 231 measures the reception level RL4 and the quality level QL4 of the radio signal according to the third command (Steps S35 and S36). The reception level RL4 and the quality level QL4 are the levels of the radio signal received in the energized state. In the energized state, the level measured by the measurement unit 231 (corresponding to the first level of the present invention) is when a radio signal amplified by the repeater 30 and a radio signal directly received from the base station BS are received. Indicates the level.

  Next, the measurement part 231 controls the power supply management part 24, and switches the repeater 30 to a non-energized state (step S37). Thereby, repeater 30 stops transmission of a radio signal.

  Next, the measurement unit 231 measures the reception level RL5 and the quality level QL5 of the radio signal (Steps S38 and S39). Reception level RL5 and quality level QL5 are levels of radio signals received when repeater 30 is in a non-energized state. In the non-energized state, the level measured by the measurement unit 231 (corresponding to the second level of the present invention) is the level of the radio signal that has arrived directly from the base station BS. This level is not affected by the ability of the repeater 30.

Next, the positioning unit 25 performs a positioning process (step S40). The positioning unit 25 generates position information indicating the position of the monitoring device 20A. Then, the output unit 232 transmits the reception level RL4, the quality level QL4, the reception level RL5, the quality level QL5, and the device ID and the position information to the host device 10A via the communication unit 22 and the antenna 21. (Step S41).
In addition, the measurement part 231 may control the power supply management part 24 after the process of step S40, and may switch the repeater 30 to an energized state. As a result, the repeater 30 resumes the operation of amplifying and transmitting the radio signal from the base station BS.

  In the host device 10A, when the data transmitted by the output unit 232 is received by the communication unit 11, the acquisition unit 122A acquires this data (step S42). Next, the processing unit 123A determines whether the reception level RL5 or the quality level QL5 is equal to or lower than the third threshold (step S43). The third threshold value for each level is a predetermined value. The process of step S43 is for grasping the level of the radio signal from the base station BS when the repeater 30 is not present. If “NO” is determined in the step S43, the process for the corresponding monitoring device 20A ends. This is because the level of the radio signal from the base station BS is sufficiently high, and it cannot be said that the repeater 30 exists in the poor reception area.

  Next, the processing unit 123A calculates a level difference ΔR45 that is a difference between the reception level RL4 and the reception level RL5 (step S44). Next, the processing unit 123A calculates a level difference ΔQ45 that is a difference between the quality level QL4 and the quality level QL5 (step S45). Then, the processing unit 123A determines whether or not the level difference ΔR45 or the level difference ΔQ45 is equal to or smaller than the fourth threshold value (step S46). The fourth threshold value for each level difference is a predetermined value. The fourth threshold is larger than the third threshold. The reason that the capability of the repeater 30 is low when the difference in reception level or the difference in quality level is equal to or less than the fourth threshold is the same as in the first embodiment described above.

  When determining that the level difference ΔR45 or the level difference ΔQ45 is equal to or smaller than the fourth threshold (step S46; YES), the processing unit 123A identifies the position indicated by the position information as a reception failure point where the reception environment of the radio signal is not good. (Step S47). The processing unit 123A causes the storage unit 13 to store information regarding the reception failure point.

Next, the processing unit 123A determines whether to generate a map indicating a poor reception area (step S48). The conditions for generating the map are not particularly limited. For example, the condition is that the number of collected reception failure points has reached a predetermined number. This is because, in order to grasp the reception failure area, it is considered that more accurate reception failure area information can be obtained by considering the distribution of a plurality of reception failure points.
If it determines with "YES" at step S48, 123 A of process parts will produce | generate the map which shows a poor reception area (step S49).

  FIG. 10 is a diagram illustrating an example of a map indicating a poor reception area. In the map M shown in FIG. 10, the display element E which shows the position of a poor reception area is shown by the image showing a map. The display element E indicates an area where a plurality of reception failure points P are distributed. The method for identifying the reception failure area based on the reception failure point is not particularly limited. For example, known clustering is used.

  The processing unit 123A transmits a map indicating the poor reception area to the computer device 40 via the communication unit 11 (step S50). The person in charge who uses the computer device 40 can use the information of the area where the reception environment is bad to set the parameters of the base station and to formulate the installation plan of the base station.

  Note that when the processing unit 123A determines that the level difference ΔR45 and the level difference ΔQ45 exceed the fourth threshold (step S46; NO), the processing unit 123A ends the processing for the corresponding monitoring device 20A.

  In the reception environment management system 1A of the second embodiment described above, the host device 10A controls the operations of the monitoring device 20A and the repeater 30 by remote operation, and collects data necessary for grasping the reception failure area. Then, the host device 10A specifies the reception failure area based on the capability of the repeater 30 specified from the collected data. Thereby, even if the person in charge does not actually investigate the reception environment of the radio signal from the base station, the reception failure area can be grasped. Therefore, the artificial work burden related to this grasp is reduced.

[Modification]
The present invention may be implemented in a form different from the above-described embodiment. Moreover, you may combine each of the modification shown below.
(Modification 1)
The process of determining the capability of the repeater 30 in steps S44 to S46 of the second embodiment described above may be replaced with the process described below. When the reception level RL5 is below the fourth threshold and the reception level RL4 exceeds the fifth threshold, the processing unit 123A has a good reception environment and the reception level RL4 is below the fifth threshold. May determine that the reception environment is bad. Further, when the quality level QL5 is equal to or lower than the fourth threshold and the quality level QL4 exceeds the fifth threshold, the processing unit 123A has a good reception environment and the quality level QL4 is equal to or lower than the fifth threshold. In some cases, it may be determined that the reception environment is bad.

FIG. 11 is a diagram for explaining abnormality determination in the host device 10A.
When the reception level RL5 is equal to or less than the fourth threshold value TH3, the reception level of the radio signal indicates that the reception environment is bad. In this case, as shown in the diagram on the left side of FIG. 11, when the reception level RL4 exceeds the fifth threshold TH4 (however, TH4> TH3), the reception level is sufficiently increased by the capability of the repeater 30. It can be said. In this case, the capability of the repeater 30 is sufficiently exhibited. On the other hand, as shown in the diagram on the right side of FIG. 11, when the reception level RL4 is equal to or lower than the fifth threshold value TH4, it indicates that the reception level to be raised by the repeater 30 is low. In this case, the capability of the repeater 30 is not fully exhibited, and it can be said that the reception environment of the radio signal is poor.

  The same can be said from the viewpoint of quality level. That is, when the quality level QL5 is equal to or lower than the fourth threshold value TH5, it indicates that the reception environment of the radio signal is poor such that the radio signal reception level requires the repeater 30. In this case, as shown in the diagram on the left side of FIG. 11, when the quality level QL4 exceeds the fifth threshold TH6 (however, TH6> TH5), the quality level is raised by the capability of the repeater 30. be able to. In this case, the capability of the repeater 30 is sufficiently exhibited. On the other hand, as shown in the diagram on the right side of FIG. 11, when the quality level QL4 is equal to or lower than the fifth threshold value TH6, it indicates that the reception level to be raised by the repeater 30 is low. In this case, the capability of the repeater 30 is not fully exhibited, and it can be said that the reception environment of the radio signal is poor.

(Modification 2)
In the first embodiment described above, the monitoring device 20 measures the reception level RL2 and the quality level QL2 according to the second command. However, the reception level RL2 and the quality level QL2 indicate the levels measured when the repeater 30 is in the energized state, similarly to the reception level RL1 and the quality level QL1. In addition, the measurement according to the first command and the measurement according to the second command may be performed without much space. Therefore, the monitoring device 20 may not measure the reception level RL2 and the quality level QL2 in accordance with the second command. In this case, the monitoring device 20 may use the reception level RL1 and the quality level QL1 instead of the reception level RL2 and the quality level QL2 to calculate a level difference and determine whether there is an abnormality in the repeater 30. .

(Modification 3)
The host device 10 or 10A may have some of the functions that the monitoring devices 20 and 20A described in the above-described embodiments have. The monitoring devices 20 and 20A may have some of the functions that the host device 10 or 10A described in the above embodiment has. For example, the monitoring devices 20 and 20A may perform the level difference calculation in steps S18, S19, S44, and S45. In this case, the monitoring devices 20 and 20A may output the calculated level difference to the host devices 10 and 10A. Furthermore, the output unit 232 of the monitoring device 20 may determine whether the repeater 30 is abnormal based on the calculated level difference and output the determination result to the host device 10A. The output unit 232 of the monitoring device 20A may determine whether there is a reception environment based on the calculated level difference and output the determination result to the host device 10A, or information on the reception failure point to the host device 10A. It may be output.

A switching unit that switches between a first state of transmitting a radio signal and a second state of stopping transmission of the amplified radio signal, and a measurement unit that measures the level of the radio signal received by the monitoring device. , Based on the measurement unit that measures the first level in the first state and the second level in the second state, the measured first level, and the second level. And a processing unit that performs processing according to the ability of the device to transmit a radio signal.

(Modification 4)
In the above-described embodiment, the presence / absence of transmission of a radio signal by the repeater 30 is changed by switching between the energized state and the non-energized state of the repeater 30. Instead, the monitoring devices 20 and 20A may control whether or not the repeater 30 transmits a radio signal while the repeater 30 is in an energized state. For example, the control unit 23 functioning as a switching unit may switch between a first state in which a radio signal is transmitted and a second state in which the transmission is stopped by transmitting a command to the repeater 30. Further, the host devices 10 and 10 </ b> A may control whether the repeater 30 transmits a radio signal. In this case, the control unit 12 functioning as a switching unit may switch between a first state in which a radio signal is transmitted and a second state in which the transmission is stopped by transmitting a command to the repeater 30.

  Furthermore, the monitoring devices 20 and 20A do not necessarily have to be connected to the repeater 30 via the power line as long as the monitoring devices 20 and 20A are provided at a position where the wireless signal transmitted by the repeater 30 is received. For example, the monitoring devices 20 and 20A receive a radio signal transmitted from the repeater 30 because the monitoring devices 20 and 20A are wirelessly connected to the repeater 30 by short-range wireless communication (for example, Bluetooth (registered trademark)). It may be secured that it is provided at the position. In this case, the monitoring device 20 may determine whether or not the repeater 30 exists within a predetermined distance based on the strength of the signal received from the repeater 30.

(Modification 5)
A part of the configuration and operation described in the above-described embodiment may be omitted. For example, the repeater maintenance system 1 may determine whether there is an abnormality in the repeater 30 based on one of the reception level and the quality level. The reception environment management system 1A may determine a reception failure point based on one of the reception level and the quality level. Further, in the repeater maintenance system 1, the process related to the first command may not be performed. In this case, the host device 10 may transmit the second command to the monitoring device 20 without transmitting the first command.
