The base station specifying unit 543 determines the distribution of the base stations in a predetermined connection state based on the determination result of the connection state determination unit 541 and the base station position information. The base station identification unit 543 identifies a base station in a congestion state, a wave stop state, or a power outage state among the plurality of base stations based on the determination result of the connection status determination unit 541 and the base station position information, and Determine the distribution of base stations. For example, the base station specifying unit 543 determines whether a certain base station is in a congestion state based on information such as the KPI of the base station.

  In addition, the base station identification unit 543 may, for example, determine a connection that is equal to or greater than a predetermined connection rate or smaller than a predetermined connection rate among a plurality of base stations based on the determination result of the connection status determination unit 541 and the base station position information. The base station having the ratio is specified, and the distribution of the base station is determined. Further, the base station identification unit 543 may request more than a predetermined number of requests or less than a predetermined number of requests among a plurality of base stations based on the determination result of the connection status determination unit 541 and the base station position information, for example.

The scale determination unit 545 determines the scale of the map including the position of the base station. For example, the scale determining unit 545 determines the scale of the map including the position of each base station according to the two-dimensional distribution of the base stations based on the base station position information, which is determined by the base station specifying unit 543. Further, the scale determination unit 545 may be configured to determine, for example, a distance between base stations having the longest difference between longitude and latitude, and determine a scale of a map that can be displayed using the distance.

  Here, the scale refers to the ratio of the actual distance reduced on the map, and the actual distance is used as the denominator, such as 1/1000, and the distance on the map is used as the numerator (generally, 1). Notation). As another notation, the scale may be indicated by a ratio such as 1: 1000, or the scale may be indicated by a scale bar in which a bar is displayed.

  Regarding the relationship between the scale and the scale bar display, for example, when the scale is “1/5000”, the scale bar display is “50 m”, and when the scale is “1 / 10,000”, the scale bar display is “100 m”. When the scale is "1 / 100,000", it may be represented by a scale bar display "1km", and when the scale is "1 / 1,000,000", it may be represented by a scale bar display "10km".

(Step SP5)
The comparison unit 547 compares the scale of the map determined by the scale determination unit 545 with a predetermined threshold. The comparison unit 547 compares, for example, whether the scale of the map determined by the scale determination unit 545 is equal to or larger than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000) or smaller than the predetermined threshold. . When the scale determined by the scale determination unit 545 is equal to or larger than the predetermined threshold (YES in step SP5), the process proceeds to step SP6. On the other hand, if the scale determined by the scale determination unit 545 is smaller than the predetermined threshold (YNO in step SP5), the process proceeds to step SP7.

(Step SP6)
When the scale of the map determined by the scale determination unit 545 is equal to or larger than a predetermined threshold, the image generation unit 549 generates a heat map map image in a display mode according to the connection information for each base station.

  FIG. 5 to FIG. 7 are diagrams illustrating an example of a display image on the display unit of the management server according to the embodiment of the present invention. Specifically, FIG. 5 is an example of a heat map map image shown in a display mode according to the number of requests for each base station. FIG. 6 is an example of a heat map map image shown in a display mode according to a connection rate for each base station. FIG. 7 is an example of a heat map map image shown in a display mode according to the connection rate for each base station having a connection rate equal to or less than a predetermined threshold among a plurality of base stations.

  As illustrated in FIG. 5, when the comparing unit 547 determines that the scale of the map determined by the scale determining unit 545 is equal to or larger than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000), The image generation unit 549 generates a heat map map image G1 shown in a display mode (for example, shades of color) according to the number of requests for each base station BI. In this heat map map image G1, colors are given around each base station BI according to the number of requests. For example, the image generation unit 549 adds a dark color around the base station BI1 having a higher number of requests, and places a base station BI2 around the base station BI2 having a smaller number of requests than the number of requests of the base station BI1. Around base station BI3, which is colored lighter than around BI1 and which has a smaller number of requests than base station BI2 or has a minimum number of requests, eg, zero, is colored. An unoccupied heat map map image G1 is generated. By generating such an image, among the base stations in the area corresponding to the heat map map image G1, a base station having a higher request number can be specified, and communication connection requests from the mobile terminal are concentrated on any base station. It can be easily grasped whether or not they are doing.

  Further, the image generation unit 549 generates the heat map map image G1 so as to include the setting image SG1, for example. On the setting screen corresponding to the setting image SG1, the setting items S1 "display target", the setting item S3 "carrier", and the setting item S4 "vendor" for selecting the base station BI to be displayed on the heat map map, and And a setting item S2 “KPI” for controlling the display mode of the heat map map image G1. The setting item S2 “KPI” includes a setting bar B1 capable of controlling the “number of requests”, a setting bar B2 capable of controlling the “connection rate”, and a tab T. For example, in the tab T, “the number of requests” or “connection rate” is configured to be selectable. In the example of FIG. 5, “the number of requests” is selected in the tab T. In this case, the user can control the “number of requests” by moving the adjustment knob K1 of the setting bar B1 that can control the “number of requests” among the setting bars B1 and B2 to the left and right. On the other hand, when the user controls the “connection rate”, the user selects “connection rate” on the tab T, and moves the adjustment knob K2 of the setting bar B2 capable of controlling the “connection rate” to the left or right, The "connection rate" can be controlled.

  On the setting screen corresponding to the setting image SG1, “convergence” is selected for the setting item S1 “display target”, and the adjustment knob K1 on the setting bar B1 is farthest to the left for the setting item S2 “KPI”. In the setting bar B2, the adjustment knob K2 is shifted to the rightmost position, "Request number" is selected in the tab T, "XXX" is selected in the setting item S3 "Carrier", and the setting item S4 "Vendor" is selected. Has not been selected at all. Therefore, as described above, in the example of FIG. 5, the base station specifying unit 543 is a congested base station among all the base stations arranged in the area corresponding to the heat map map image G1, and the carrier “ The base station provided by “XXX” is specified. Then, the image generation unit 549 generates a heat map map image G1 shown in a display mode corresponding to the number of requests for each base station BI specified by the base station specification unit 543.

  In addition, the image generation unit 549 generates an image including the scale bar SB1 such that, for example, the scale bar “XXm” SB1 corresponding to the scale of the map of the generated heat map map image is arranged at the lower right of the heat map map image G1. Generate Note that the image generation unit 549 may generate an image such that the scale bar SB1 is included in the heat map map image G1. By generating such an image, the user can easily grasp the scale of the map in the displayed map image.

  As shown in FIG. 6, when the scale of the map determined by the scale determination unit 545 is equal to or larger than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000), the image generation unit 549 generates the map for each base station BI. A heat map map image G2 is generated in a display mode (for example, shade of color) according to the connection rate.

  For example, on the setting screen corresponding to the setting image SG2, “convergence” is selected for the setting item S1 “display target”, and the adjustment knob K1 on the setting bar B1 is shifted to the left for the setting item S2 “KPI”. In the setting bar B2, the adjustment knob K2 is shifted to the rightmost position, the "connection rate" is selected in the tab T, "XXX" is selected in the setting item S3 "carrier", and the setting item S4 " No vendor has been selected. Accordingly, in the example of FIG. 6, the base station specifying unit 543 is a congested base station among all the base stations arranged in the area corresponding to the heat map map image G2, and is provided by the carrier “XXX”. Specify the base station to perform. Then, the image generation unit 549 generates a heat map map image G2 shown in a display mode according to the connection rate for each base station BI specified by the base station specification unit 543.

  Specifically, the image generation unit 549 has a darker color around the base stations BI4, BI5, and BI6 having a lower connection rate, and has a connection rate larger than the connection rate of the base stations BI4, BI5, and BI6. The periphery of the base stations BI7, BI8, BI9, and BI10 is colored lighter than the periphery of the base stations BI4, BI5, and BI6, and has a higher connection rate than the connection rates of the base stations BI7, BI8, BI9, and BI10. Alternatively, a heat map map image G2 without a color is generated around the base station BI11 or the like having the maximum connection rate, for example, 100%. By generating such an image, among the base stations in the area corresponding to the heat map map image G1, a base station having a lower connection rate can be specified, and any base station and communication associated with the base station can be identified. It is possible to easily grasp whether the connection rate with the mobile terminal located in the area is decreasing.

  As shown in FIG. 7, when the scale of the map determined by the scale determination unit 545 is equal to or larger than a predetermined threshold value (for example, 1 / 1,000,000 or 1: 1,000,000), the image generation unit 549 generates a plurality of base stations. Among them, a heat map map image G3 is generated in a display mode corresponding to the connection rate for each base station whose connection rate is equal to or less than a predetermined threshold.

  For example, on the setting screen corresponding to the setting image SG3, “convergence” is selected for the setting item S1 “display target”, and the adjustment knob K1 on the setting bar B1 of the setting item S2 “KPI” is shifted to the leftmost. In the setting bar B2, the connection rate corresponding to the position of the adjustment knob K2 is 80%, and "XXX" is selected for the setting item S3 "Carrier". Therefore, in the example of FIG. 7, the base station specifying unit 543 is a congested base station having a connection rate of 80% or less among all the base stations arranged in the area corresponding to the heat map map image G3. Then, the base station provided by the carrier “XXX” is specified. Then, the image generating unit 549 generates a heat map map image G3 shown in a display mode according to the connection rate for each base station BI specified by the base station specifying unit 543.

  Specifically, the image generation unit 549 is colored around the base station having a lower connection rate, for example, the base station BI12, and has a connection rate greater than or lower than the connection rate of the base station BI12. An uncolored heat map map image G3 is generated around a 100% base station, for example, the base station BI13. By generating such an image, among the base stations in the area corresponding to the heat map map image G3, a base station having a connection rate equal to or lower than a predetermined connection rate can be specified. It is possible to easily grasp whether the connection rate with the mobile terminal located in the assigned communication area has decreased.

  The base station specifying unit 543 may be configured to specify a congested base station that is equal to or more than a predetermined number of requests among all base stations arranged in an area corresponding to the map image. Then, the image generation unit 549 may be configured to generate a heat map map image in a display mode corresponding to the number of requests for each base station specified by the base station specification unit 543. In addition, the base station specifying unit 543 specifies a congested base station that is equal to or less than a predetermined connection rate and equal to or more than a predetermined number of requests among all the base stations arranged in the area corresponding to the map image. It may be configured as follows. Then, the image generating unit 549 may be configured to generate a heat map map image shown in a display mode according to the connection rate and the number of requests for each base station specified by the base station specifying unit 543.

  In addition, as shown in FIGS. 5 to 7, the image generation unit 549 is configured to generate a heat map map image colored around the congested base station. Here, the range to be colored may be within the range of the communication area associated with each base station. Further, the range to be colored may be appropriately changed according to the connection status or the degree of association between a plurality of base stations. For example, a base station with a smaller connection rate and a larger number of requests may be colored in a wider range. In addition, for example, the connection status determination unit 541 groups a plurality of adjacent base stations, determines a connection status for each of the grouped base stations, and the image generation unit 549 determines the connection status by the connection status determination unit 541. Based on the base station group, a heat map map image colored around each base station group may be generated.

(Step SP7)
When the scale of the map determined by the scale determination unit 545 is smaller than a predetermined threshold, the image generation unit 549 reduces the number of base stations specified by the base station specification unit 543 included in the area for each predetermined area. A map image shown in a corresponding display mode is generated.

  8 to 10 are diagrams illustrating examples of display images on the display unit of the management server according to the embodiment of the present invention. Specifically, FIG. 8 is an example of a map image displaying, for each predetermined area, the number of base stations included in the area and having a connection rate equal to or lower than a predetermined connection rate. FIG. 9 is an example of a map image that displays, for each predetermined area, the number of base stations included in the area and having the number of requests equal to or greater than the predetermined number of requests. FIG. 10 is an example of a map image displaying, for each predetermined area, the number of base stations having a connection rate equal to or less than a predetermined connection rate and having a request number equal to or greater than a predetermined request number, included in the area. It is.

  As shown in FIG. 8, when the scale of the map determined by the scale determination unit 545 is smaller than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000), the image generation unit 549 outputs a predetermined area included in the map. Each time, a map image G4 displaying the number D of base stations having a connection rate equal to or lower than a predetermined connection rate, which is arranged in the area, is generated.

  For example, on the setting screen corresponding to the setting image SG4, “convergence” is selected for the setting item S1 “display target”, and the adjustment knob K1 on the setting bar B1 of the setting item S2 “KPI” is shifted leftmost. In the setting bar B2, the connection rate corresponding to the position of the adjustment knob K2 is, for example, 80%, and "XXX" is selected as the setting item S3 "Carrier". Therefore, in the example of FIG. 8, the base station specifying unit 543 is a congested base station having a connection rate of 80% or less among all base stations arranged on the map corresponding to the map image G4. The base station provided by the carrier “XXX” is specified. Then, the image generation unit 549 generates, for each prefecture included in the map, a map image G4 that displays the number D of base stations having a connection rate of 80% or less, which are arranged in the prefecture. . By generating such an image, for each predetermined area included in the map corresponding to the map image G4, the number of base stations having a connection rate equal to or lower than a predetermined connection rate arranged in the area can be easily specified. It is possible to easily understand which area has more base stations in which congestion has occurred.

  As shown in FIG. 9, when the scale of the map determined by the scale determination unit 545 is smaller than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000), the image generation unit 549 outputs a predetermined area included in the map. Each time, a map image G5 that displays the number D of base stations having the number of requests equal to or more than the predetermined number of requests arranged in the area is generated.

  For example, on the setting screen corresponding to the setting image SG5, "Congestion" is selected for the setting item S1 "Display target", and a request corresponding to the position of the adjustment knob K1 on the setting bar B1 for the setting item S2 "KPI". The number is, for example, 500, the adjustment knob K2 on the setting bar B2 is farthest to the right, and “XXX” is selected as the setting item S3 “Carrier”. Therefore, in the example of FIG. 9, the base station specifying unit 543 is a congested base station having 500 or more requests among all base stations arranged on the map corresponding to the map image G5. The base station provided by "XXX" is specified. Then, the image generation unit 549 generates, for each prefecture included in the map, a map image G5 displaying the number D of base stations having the number of requests of 500 or more, which are arranged in the prefecture. By generating such an image, for each predetermined area included in the map corresponding to the map image G5, the number of base stations having the number of requests equal to or more than the predetermined number of requests arranged in the area can be easily specified. It is possible to easily understand which area has more base stations in which congestion has occurred.

  As shown in FIG. 10, when the scale of the map determined by the scale determination unit 545 is smaller than a predetermined threshold (for example, 1 / 1,000,000 or 1: 1,000,000), the image generation unit 549 outputs a predetermined area included in the map. Each time, a map image G6 is generated which displays the number D of base stations having a connection rate equal to or less than a predetermined connection rate and having a request number equal to or greater than a predetermined request number, arranged in the area.

  For example, on the setting screen corresponding to the setting image SG6, “congestion” is selected for the setting item S1 “display target”, and a request corresponding to the position of the adjustment knob K1 on the setting bar B1 for the setting item S2 “KPI”. The number is, for example, 500, the connection rate corresponding to the position of the adjustment knob K2 in the setting bar B2 is, for example, 90%, and “XXX” is selected as the setting item S3 “Carrier”. Therefore, in the example of FIG. 10, the base station specifying unit 543 determines that the connection rate is 90% or less and the number of requests is 500 or more among all the base stations arranged on the map corresponding to the map image G5. A base station that is in a certain congestion state and that is provided by the carrier “XXX” is specified. Then, the image generation unit 549 determines, for each prefecture included in the map, a base having a connection rate of 90% or less and a connection rate of 90% or less and a request number of 500 or more arranged in the prefecture. A map image G6 displaying the number D of stations is generated. If such an image is generated, for each predetermined area included in the map corresponding to the map image G6, a connection rate that is less than or equal to a predetermined connection rate and that is arranged in the area and that has a predetermined number of requests The number of base stations having the above-mentioned number of requests can be easily specified, and it can be easily grasped in which area the more congested base stations exist.

(Step SP8)
The display unit 58 illustrated in FIG. 3 displays the images G1 to G6 generated by the image generation unit 546.

  As described above, according to the embodiment of the present invention, based on the determination result of the connection status determination unit that determines the connection status for each base station based on the base station identification information and the connection information and the base station position information, By generating a map image indicating the determination result according to the scale of the map, the base station to be controlled can be easily and accurately determined.

<Other modifications>
The embodiments described above are intended to facilitate understanding of the present invention, and are not to be construed as limiting the present invention. The present invention can be changed / improved (for example, combining the embodiments, omitting some of the configurations of the embodiments) without departing from the spirit thereof, and the present invention also includes equivalents thereof. It is.

  In the above embodiment, in the heat map map images G1 to G3 (see FIGS. 5 to 7) generated by the image generation unit, the difference in the connection status of each base station is expressed by using light and shade of colors. The present invention is not limited to this, and may be displayed using highlighted display of different colors or different patterns.

  When the base station to be controlled is specified, the management server may be configured to generate a control command for controlling the base station and transmit the control command to each base station. In the management server, the map image generation processing and the control command generation processing may be performed in combination. For example, in the management server, after the image generation unit generates a map image and displays the image, a control command is issued to the specification result of the base station specification unit or the base station specified based on an instruction from the user. May be configured to be transmitted.

  Each step SP of the flowchart shown in FIG. 4 does not necessarily have to be executed as described above. For example, SP3 may be executed after SP4. In addition, when the user changes each setting item displayed on the setting screen after the map image is displayed in FIGS. 5 to 10, the image generation unit generates a map image corresponding to the change operation. Specifically, in the example of FIG. 7, the image generation unit is a congested base station whose connection rate is 80% or less, which is specified by the base station specification unit 543, and is provided by the carrier “XXX”. A heat map map image G3 shown in a display mode according to the connection rate for each base station is generated. However, when the user subsequently changes the connection rate from 80% to 90% in the setting item S2 on the setting screen, the image generation unit determines that the connection rate specified by the base station specifying unit 543 is 90% or less. The base station in the state may be configured to generate a new heat map map image shown in a display mode according to a connection rate for each base station provided by the carrier “XXX”.
