  Next, with reference to FIG.7 and FIG.8, the measuring method which concerns on this embodiment is demonstrated. FIG. 7 is an explanatory diagram of the measurement method according to the present embodiment. FIG. 8 is a flowchart illustrating an example of the procedure of the measurement method according to the present embodiment.

  FIG. 7 shows an example of the movement route of the terminal device 10. In FIG. 7, the terminal device 10 passes through each sector in the order of non-specific sector A, specific sector B, non-specific sector C, specific sector D, and non-specific sector E as time passes. .

  The communication area detection unit 12 of the terminal device 10 detects specific sectors and non-specific sectors based on the specific sector list file 52. The communication area detection unit 12 acquires base station sector identification information (a set of a base station ID and a sector ID) received by the radio unit 33 from the radio base station. The communication area detection unit 12 determines whether or not the acquired base station sector identification information exists in the specific sector list file 52. As a result of the determination, the communication area detection unit 12 determines that a specific sector is detected when it exists in the specific sector list file 52, and detects that a non-specific sector is detected when it does not exist in the specific sector list file 52. decide.

  When the non-specific sector is detected as a result of the detection by the communication area detection unit 12, the measurement control unit 13 of the terminal device 10 determines the communication status data of the measurement unit 11 according to the non-specific sector measurement method of the measurement catalog file 53. Control the measurement of The measurement unit 11 measures communication status data under the control of the measurement control unit 13. Here, as an example of the non-specific sector measurement method according to the present embodiment, communication status data is measured at a non-specific sector measurement interval (for example, every 15 minutes). The non-specific sector measurement interval is described in the measurement catalog file 53.

  The measurement control unit 13 of the terminal device 10 measures the communication status data of the measurement unit 11 according to the measurement method of the specific sector of the measurement catalog file 53 when the specific sector is detected as a result of the detection by the communication area detection unit 12. To control. The specific sector measurement method is different from the non-specific sector measurement method. Hereinafter, with reference to FIG. 8, an example of the procedure of the measurement method in the case where a specific sector is detected will be described.

(Step S11) The measurement control unit 13 determines whether or not to measure the communication status data of the measurement unit 11. This measurement execution determination method will be described. The measurement control unit 13 determines the communication status data of the detected specific sector based on the coincidence between the specific sector detected by the communication area detection unit 12 and the record (measurement history data) of the specific sector in the measurement history storage unit 15. It is determined whether or not to perform the measurement. An example of the conditions for this determination is shown below.

(Example of measurement execution judgment conditions)
When both condition A and condition B are satisfied, it is determined that the measurement is not performed. In other cases, it is determined that the measurement is performed.
(Condition A) The specific sector (specific sector identification information) detected by the communication area detection unit 12 is the specific sector (measurement threshold value) that has been measured within the most recent predetermined number of times (measurement count threshold) among the specific sectors that have been measured in the past ( Coincides with specific sector identification information). The measurement frequency threshold is described in the measurement catalog file 53.
(Condition B) The interval between the most recent measurement date and time and the current date and time of the specific sector (specific sector identification information) detected by the communication area detection unit 12 is within a predetermined time (shortest measurement interval). The shortest measurement interval is described in the measurement catalog file 53.

  According to the example of the measurement execution determination condition described above, it is possible to obtain an effect of preventing frequent measurement when the terminal device 10 remains near the boundary of a specific sector. When the terminal device 10 remains near the boundary of a specific sector, detection of the same specific sector may be repeated in a short time. At this time, if measurement is performed every time the same specific sector is detected, the number of times of measurement of the same specific sector may be excessive. For this reason, according to the example of the measurement execution determination condition described above, the measurement of the same specific sector is limited not to be repeated excessively in a short time.

(Step S12) As a result of the determination in step S11, if the measurement is performed, the process proceeds to step S13. If the measurement is not performed, the process of FIG. 8 is terminated.

(Step S13) The measurement control unit 13 calculates the scheduled measurement time. The calculation method of the scheduled measurement time is different between the specific sector and the non-specific sector. As an example of this embodiment, in the non-specific sector, the scheduled measurement time is calculated at a non-specific sector measurement interval (for example, every 15 minutes). In the specific sector, the measurement scheduled time is calculated by a calculation method different from that for the non-specific sector. An example of a method for calculating the scheduled measurement time for a specific sector is shown below.

(Example 1 of scheduled measurement time calculation method for a specific sector)
The scheduled measurement time is assumed to be immediate. In this case, the measurement control unit 13 instructs the measurement unit 11 to perform measurement when it is determined that measurement is to be performed as a result of the determination in step S11. The measurement unit 11 performs measurement immediately in response to the measurement instruction.

(Example 2 of calculation method for scheduled measurement time of specific sector)
A measurement time is randomly selected from measurement time candidates within the measurement time range, and a scheduled measurement time is calculated using the selected measurement time. The measurement time range is described in the measurement catalog file 53. A measurement time candidate exists for each measurement time interval. The measurement time interval is described in the measurement catalog file 53. For example, when the measurement time range is 0 second to 300 seconds and the measurement time interval is 1 second, the measurement time candidates are “0 seconds, 1 second, 2 seconds” every other second from 0 seconds to 300 seconds. Seconds, ... 299 seconds, 300 seconds ". Randomly select the number of measurement times selected from the measurement time candidates and use it for calculation of the scheduled measurement time. The selected number of measurement times is described in the measurement catalog file 53. For example, when the number of measurement time selections is 2, select two measurement times at random from the measurement time candidates “0 seconds, 1 second, 2 seconds,..., 299 seconds, 300 seconds”. To do. Here, it is assumed that 5 seconds and 100 seconds are selected. Using the two measurement times “5 seconds” and “100 seconds”, 5 seconds after the current time is determined as the first scheduled measurement time, and 100 seconds after the current time is scheduled for the second measurement. Decide on time.
In Example 1 of the above-described measurement scheduled time calculation method for a specific sector, the measurement is performed immediately after the detection of the specific sector, so the measurement location is biased near the boundary of the specific sector. For example, in a specific sector where a railroad track passes, it is conceivable that the measurement location is biased to substantially the same place on the track near the boundary of the specific sector. On the other hand, according to Example 2 of the scheduled measurement time calculation method for the specific sector, the measurement location is prevented from being biased near the boundary of the specific sector as in Example 1 of the measurement scheduled time calculation method for the specific sector, and the measurement locations are distributed. Effect is obtained.

(Example 3 of calculation method for scheduled measurement time of specific sector)
The scheduled measurement time is calculated at a specific sector measurement interval. However, the specific sector measurement interval is different from the non-specific sector measurement interval. The specific sector measurement interval is described in the measurement catalog file 53.

Any one of Example 1, Example 2, and Example 3 of the above-described measurement scheduled time calculation method for a specific sector may be used alone, or a plurality may be used in combination. Also,
You may make it calculate the measurement scheduled time of a specific sector so that the frequency of measurement of a specific sector may be changed from the frequency of measurement of a non-specific sector. The frequency of measurement of a specific sector may be increased or decreased compared to the frequency of measurement of a non-specific sector.

(Step S14) The measurement control unit 13 instructs the measurement unit 11 to perform measurement in accordance with the scheduled measurement time. The measurement unit 11 performs measurement immediately in response to the measurement instruction. The measurement unit 11 measures communication status data indicating the status of communication via radio communication performed by the radio unit 33 with the radio base station.

  For example, the measurement unit 11 measures data indicating the reception intensity of the radio wave received from the radio base station by the radio unit 33 as communication status data. For example, the measurement unit 11 measures data indicating the communication speed of communication performed by the wireless unit 33 as communication status data. Alternatively, the measurement unit 11 determines the presence or absence of an end-to-end response (for example, a reply of an ACK signal) of communication performed by the wireless unit 33, and uses data indicating the presence or absence of the response as communication status data. Generate.

(Step S <b> 15) The measurement control unit 13 acquires communication state data as a measurement result from the measurement unit 11. The measurement control unit 13 stores measurement data including the acquired communication status data, measurement date / time information, specific sector identification information, and information indicating the specific sector in the measurement data storage unit 14. Further, the measurement control unit 13 stores measurement history data including measurement date information and specific sector identification information in the measurement history storage unit 15 as measurement history data of the measurement.
Thereafter, the process of FIG. 8 is terminated.

  In the present embodiment, the measurement data storage unit 14 and the measurement history storage unit 15 are provided separately. However, the measurement data storage unit 14 and the measurement history storage unit 15 may be integrated. For example, only the measurement data storage unit 14 shown in FIG. 5 may be provided, and the measurement data storage unit 14 may be used as the measurement history storage unit 15.

  Next, a modification according to this embodiment will be described.

(Modification 1)
FIG. 9 is an explanatory diagram of Modification 1 according to the present embodiment. In the first modification, a regulation rate of measurement is provided. The restriction rate is a rate at which measurement of communication status data of the measurement unit 11 is not performed. The restriction rate may be a different value between the specific sector and the non-specific sector. The regulation rate is described in the measurement catalog file 53.

  The measurement control unit 13 executes a measurement instruction to the measurement unit 11 according to the regulation rate. In the example of FIG. 9, the restriction rate of the specific sector is “0%”, and the restriction rate of the non-specific sector is “30%”. In the example of FIG. 9, the measurement control unit 13 applies the restriction rate “0%” when a specific sector is detected as a result of the detection by the communication area detection unit 12. Thereby, the measurement control unit 13 does not restrict the measurement instruction to the measurement unit 11 and executes the measurement instruction to the measurement unit 11 according to the scheduled measurement time. Therefore, when a specific sector is detected, the measurement is performed according to the scheduled measurement time.

  On the other hand, in the example of FIG. 9, the measurement control unit 13 applies the restriction rate “30%” when the non-specific sector is detected as a result of the detection by the communication area detection unit 12. As a result, the measurement control unit 13 executes the measurement instruction to the measurement unit 11 by reducing it by 30% from the scheduled measurement time. Therefore, when non-specific sectors are detected, only 70% of the scheduled measurement time is measured.

(Modification 2)
In the second modification, the ratio of the number of communication status data items stored in the measurement data storage unit 14 for specific sectors and non-specific sectors is provided. There is an upper limit to the number of communication status data that can be stored in the measurement data storage unit 14. The ratio of the communication status data of the specific sector and the communication status data of the non-specific sector is provided with respect to the upper limit number of communication status data (total number of maximum logs) that can be stored in the measurement data storage unit 14. The total log upper limit number is described in the measurement catalog file 53.

  For example, the upper limit number (non-specific sector log upper limit number) of non-specific sector communication status data that can be stored in the measurement data storage unit 14 is described in the measurement catalog file 53. The measurement control unit 13 acquires the number of measurement data of the non-specific sector in the measurement data storage unit 14 when the non-specific sector is detected as a result of the detection by the communication area detection unit 12. The measurement control unit 13 executes a measurement instruction to the measurement unit 11 when the acquired number is less than the non-specific sector log upper limit number, and when the acquired number reaches the non-specific sector log upper limit number. Does not execute a measurement instruction to the measurement unit 11. On the other hand, if the detection of the specific sector is detected as a result of the detection by the communication area detection unit 12, the measurement control unit 13 determines that the total number of measurement data in the measurement data storage unit 14 is less than the total log upper limit number. The measurement instruction to the measurement unit 11 is executed, and when the total number of measurement data reaches the total log upper limit number, the measurement instruction to the measurement unit 11 is not executed.

(Modification 3)
FIG. 10 is an explanatory diagram of Modification 3 according to the present embodiment. In the third modification, the measurement method is changed according to the sector (passing sector) through which the terminal device 10 passes. The correspondence between the passing sector and the measurement method is described in the measurement catalog file 53. In the example of FIG. 10, when the terminal device 10 moves from a non-specific sector to a specific sector, the non-specific sector measurement method is applied, and when the terminal device 10 moves from a specific sector to a specific sector, Apply the measurement method. The communication area detection unit 12 holds a history of detection results of a specific sector and a non-specific sector (sector detection history). The measurement control unit 13 determines the passing sector of the terminal device 10 based on the sector detection history.

In the example of FIG. 10, the measurement control unit 13 determines that if the detection result of the communication area detection unit 12 indicates that a specific sector is detected and the most recent detection result of the sector detection history is a non-specific sector, Apply the measurement method. On the other hand, in the example of FIG. 10, the measurement control unit 13 detects that the specific sector is detected when the detection result of the most recent sector detection history is a specific sector in the case where the detection of the specific sector is detected as a result of the detection by the communication area detection unit 12. Apply the measurement method.
In this way, the combination of sector types (specific sector or non-specific sector) before and after the movement of the terminal device 10 “movement from a specific sector to a specific sector, movement from a non-specific sector to a non-specific sector, non-specific from a specific sector Depending on the movement to the sector or the movement from the non-specific sector to the specific sector, it may be determined whether to apply the specific sector measurement method or the non-specific sector measurement method.

The correspondence relationship between the passing sector and the measurement method is determined based on the terminal type, the frequency used in the sector, the measurement condition of the wireless communication network, or the like. For example, when the communication quality differs depending on the terminal specifications such as the model and OS (Operating System), the correspondence between the passing sector and the measurement method is determined for each type of terminal specifications. For example, when the communication quality differs depending on the used frequency of the sector, the correspondence relationship between the passing sector and the measurement method is determined for each used frequency of the sector. For example, when the desired number of measurement data differs depending on the radio access method of the radio communication network, the correspondence relationship between the passing sector and the measurement method is determined for each sector radio access method.
Further, it may be determined whether to apply a specific sector measurement method or a non-specific sector measurement method according to the combination of sectors (base station sector identification information) before and after the terminal device 10 moves. Good. Thereby, the measurement data number specifying the position of the sector at the measurement location can be adjusted.

(Modification 4)
FIG. 11 is an explanatory diagram of Modification 4 according to the present embodiment. In the fourth modification, the type of the same sector (specific sector or non-specific sector) is changed according to the time zone. In the specific sector list file 52, a time zone for making a specific sector is added.

  In the example of FIG. 11, a graph of the acquisition result of the number of measurement data per time in the sector Z is shown. In the example of FIG. 11, the time zone “from 0 o'clock to 6 o'clock” that is less than the threshold value “1000” of the number of measurement data is determined to make the sector Z a specific sector. On the other hand, the time zone “from 7 o'clock to 23 o'clock” that is equal to or greater than the threshold value “1000” for the number of measurement data is determined to make sector Z a non-specific sector. The specific sector list file 52 includes specific sector identification information of the sector Z and information indicating the time zone “from 0:00 to 6 o'clock”. When detecting the sector Z, the communication area detecting unit 12 determines that the specific sector is detected in the time zone “from 0 o'clock to 6 o'clock” based on the specific sector list file 52, and other times The band “from 7 o'clock to 23 o'clock” is determined to have detected a non-specific sector. As a result, in the sector Z, the time zone “from 0 o'clock to 6 o'clock” is measured by the specific sector measurement method, and the time zone “from 7 o'clock to 23 o'clock” is measured by the non-specific sector measurement method. Is executed.

  A method for determining the time zone for the specific sector may be arbitrary. For example, in the sector Z, a time zone in which the sector Z is a specific sector may be determined based on a time zone in which many people gather (for example, a time zone in which an event is held). Thereby, communication quality data in a time zone in which communication is congested in the sector Z can be acquired with priority. Further, the measurement management server 71 may generate the specific sector list file 52 in accordance with a method for determining a time zone for a specific sector.

(Modification 5)
In the embodiment described above, the sector of the radio base station is used as the communication area, and the sector of the radio base station is determined by the set of the base station ID and the sector ID. In the fifth modification, the communication area is determined by latitude and longitude. The specific communication area information according to the modified example 5 is latitude / longitude indicating the specific communication area. In the modified example 5, the communication area detection unit 12 includes a positioning function for acquiring the latitude and longitude of the terminal device 10. As the positioning function, for example, GPS (Global Positioning System) may be used, or the wireless unit 33 may acquire position information of a wireless base station that performs wireless communication.

  The communication area detection unit 12 compares the latitude / longitude of the terminal device 10 acquired by the positioning function with the latitude / longitude of the specific communication area information, and determines whether or not a specific communication area is detected. If no specific communication area is detected, the communication area detection unit 12 determines that a communication area other than the specific communication area (non-specific communication area) is detected.

  When the specific communication area is detected, the measurement control unit 13 applies the same measurement method as the specific sector measurement method according to the embodiment described above. On the other hand, the measurement control unit 13 applies a measurement method similar to the measurement method of the non-specific sector according to the above-described embodiment when the non-specific communication area is detected.

(Modification 6)
In the sixth modification, the communication area is a combination of a geographical area and a communication frequency area. For example, a radio base station sector indicated by base station sector identification information (a set of base station ID and sector ID) is composed of a geographical area and a frequency band used by the sector. Even if the sector of the same geographical area of the same radio base station, if the used frequency band of the sector is different, the sector ID is different, and therefore the base station sector identification information is different. As a result, a specific sector can be set for each used frequency band of the sector.

  Any one of the above-described modified examples 1-6 may be applied alone, or a plurality may be applied in combination.

  According to the above-described embodiment, regarding measurement control of communication status data, it is possible to perform control of measurement that differs between a specific sector (specific communication area) and a non-specific sector (non-specific communication area). Thereby, the effect that adjustment of the number of measurement data of each communication area of radio | wireless communication networks, such as a mobile telephone network, can be performed is acquired.

  For example, when a situation occurs in which the number of measurement data per day of a certain sector does not reach a desired number, the sector is set as a specific sector so that the number of measurement data per day of the specific sector is increased. By changing the measurement method of a specific sector from the measurement method of a non-specific sector, the number of measurement data per day for the sector can be increased. For example, by increasing the frequency of measurement of a specific sector over the frequency of measurement of a non-specific sector, the number of measurement data per day for the sector can be increased.

  For example, when a situation occurs in which the number of measurement data per day for a certain sector is excessive, the measurement method for a specific sector is set such that the sector is set as a specific sector and the number of measurement data per day for the specific sector is reduced. Is changed from the measurement method of the non-specific sector, the number of measurement data per day of the sector can be reduced. For example, by reducing the frequency of measurement of a specific sector over the frequency of measurement of a non-specific sector, the number of measurement data per day for the sector can be reduced.

  For example, when the difference in the number of measured data per day between sector X and sector Y is unacceptably large, one sector is set as a specific sector, and the difference in the number of measured data per day between a specific sector and a non-specific sector By changing the measurement method of the specific sector from the measurement method of the non-specific sector so as to reduce the difference, the difference in the number of measurement data per day between the sector X and the sector Y can be reduced. For example, the difference in the number of measurement data per day between the sector X and the sector Y can be reduced by changing and adjusting the measurement frequency of a specific sector or the measurement frequency of a non-specific sector.
