JP 2005-18375 A

  In the mobile phone system, communication is performed by the base station device assigning a channel to the terminal device. By monitoring the number of terminal devices connected to the base station device, it is possible to grasp the congestion of the mobile phone system. In the commercial wireless system, a group is formed by a plurality of terminal devices, and the base station device assigns a channel to the group. In such a business wireless system, calls within a group are mainly used and a one-to-many call form is formed. In addition, when a terminal device of the same group is connected to each of the plurality of base station devices and a call is started, the channel of the base station device to which the terminal device of the group is connected is used one channel at a time. Is done. Therefore, there are cases where channels cannot be allocated (hereinafter referred to as `` busy '') when a call request occurs exceeding the number of channels that can be set in the base station device by performing a call simultaneously with a plurality of groups. Occur. In the one-to-many communication mode, the use of the channel of the base station device per call and the communication amount between the base station devices are more complicated than a general one-to-one call.

A reception unit that receives information on the number of busys generated in the group, and a processing unit that generates display data for displaying the busy number for each base station apparatus based on the information received in the reception unit.

  Another aspect of the present invention is a monitoring method. In this method, a plurality of groups including a plurality of terminal devices are formed, and each of the plurality of base station devices allocates a channel in units of groups, whereby one terminal device included in the group to which the channel is allocated To monitoring the communication system in which communication to the remaining terminal devices included in the group is performed, and information on the number of busys that occurred due to being included in the group registered in each base station device And a step of generating display data for displaying the busy number for each base station apparatus based on the received information.

Example 1
Before describing the present invention specifically, an outline will be given first. Embodiment 1 of the present invention relates to a business wireless system including a plurality of base station devices connected to a network, a plurality of terminal devices connected to each base station device, and a monitoring device connected to the network. In a commercial wireless system, a group is formed by a plurality of terminal devices. The base station apparatus assigns an uplink channel and a downlink channel to the group. Under such circumstances, one terminal device in the group (hereinafter referred to as “transmitting device”) transmits a signal on the uplink channel, and another terminal device in the group (hereinafter referred to as “receiving device”). Receives a signal on the downlink channel. Note that a base station apparatus different from the base station apparatus to which the transmitting apparatus is connected also assigns a downlink channel to the group, so that a receiving apparatus connected to the base station apparatus can also receive signals. Further, the same processing is performed for another group, but basically communication between different groups is not performed.

  In commercial wireless systems, channel allocation is done in units of groups, so as described above, the use of channels of base station devices per call and the amount of communication between base station devices can be evaluated only by the number of terminal devices. It becomes complicated. In order to grasp the state of communication when a call within the group is made, the monitoring device included in the business wireless system according to the present embodiment executes the following processing. The monitoring device acquires the number of busys generated in each base station device for each group. The monitoring device displays the busy number generated in each base station device on the map for the selected group. In this way, since the busy state of group calls at each base station device is collectively displayed on the map, it is easy to determine whether system resources are insufficient or sufficient.

  FIG. 1 shows a configuration of a business wireless system 100 according to the first embodiment of the present invention. The commercial radio system 100 is generically referred to as a first base station apparatus 10a, a second base station apparatus 10b, a third base station apparatus 10c, a fourth base station apparatus 10d, and a terminal apparatus 12, which are collectively referred to as a base station apparatus 10. A first terminal device 12a, a second terminal device 12b, a third terminal device 12c, a fourth terminal device 12d, a network 14, and a monitoring device 20 are included. The first base station apparatus 10a forms the first area 16a, the second base station apparatus 10b forms the second area 16b, the third base station apparatus 10c forms the third area 16c, and the fourth The base station device 10d forms a fourth area 16d. Here, the first area 16a, the second area 16b, the third area 16c, and the fourth area 16d are collectively referred to as an area 16. The number of base station devices 10 and the number of terminal devices 12 are not limited to “4”.

  The first base station apparatus 10 a to the fourth base station apparatus 10 d are connected via the network 14. The base station apparatus 10 can set a plurality of channels and assigns each channel to a group. A known technique may be used for the channel. Here, as an example, a plurality of channels are multiplexed by FDMA (Frequency Division Multiple Access) / FDD (Frequency Division Duplex). For example, the first base station apparatus 10a sets Ch1 and Ch3 to Ch6 as downlink channels, and sets Ch2 and Ch7 to Ch10 as uplink channels. Here, Ch1 is used for the downlink control channel, and Ch2 is used for the uplink control channel. Further, Ch3 and Ch7 are assigned to the same group as one combination. The same applies to Ch4 to Ch6 and Ch8 to Ch10. Other base station apparatuses 10 similarly set channels, but the number of channels that can be set may be different for each base station apparatus 10. Further, Ch1 and Ch2 are assumed to be used for the downlink control channel and the uplink control channel in common across all base station apparatuses 10.

  The terminal device 12 is a wireless terminal that can communicate with another terminal device 12 via the base station device 10. Here, it is assumed that a call is made as communication. Data communication may be performed. When the terminal device 12 enters the area 16, the terminal device 12 requests location registration to the base station device 10 that forms the area 16. At that time, registration of the group to be used is also required. These requests are transmitted by being included in the uplink control channel of Ch2. The uplink control channel is transmitted by random access. In response to the request, the base station device 10 registers the terminal device 12 in units of groups.

  When a call is generated in one terminal device 12, the terminal device 12 transmits an uplink control channel including a call request in Ch2. The base station apparatus 10 that has received the uplink control channel uses the terminal apparatus 12 as the transmission apparatus described above, and allocates a channel to the group including the transmission apparatus. The channel here is a generic term for a downlink channel and an uplink channel. The base station apparatus 10 requests the other base station apparatus 10 to allocate a channel to the group via the network 14. The other base station apparatus 10 confirms whether the group is registered in response to the request. When registered, the other base station apparatus 10 allocates a channel to the group.

  The base station apparatus 10 and the other base station apparatus 10 transmit a downlink control channel including information on the allocated channel to the terminal apparatus 12. The receiving device and the transmitting device that are the remaining terminal devices 12 included in the group recognize the allocated channel by receiving the downlink control channel. The transmission apparatus transmits a signal to the base station apparatus 10 using the allocated uplink channel. The signal includes a digitized audio signal. When the receiving apparatus is included in the group including the transmitting apparatus, the base station apparatus 10 transmits a signal to the receiving apparatus using the allocated downlink channel. In addition, the base station apparatus 10 transmits the received signal to another base station apparatus 10. The other base station apparatus 10 transmits a signal to the receiving apparatus using the allocated downlink channel. The receiving device reproduces an audio signal based on the received signal and outputs audio from the speaker.

  In this way, a plurality of groups including a plurality of terminal devices 12 are formed. Further, each of the plurality of base station apparatuses 10 assigns a channel in units of groups. As a result, communication is performed from one terminal device 12 included in the group to which the channel is assigned to the remaining terminal devices 12 included in the group.

  Note that the transmission device and the reception device may be interchanged among the plurality of terminal devices 12 included in the group. When a signal to be transmitted is generated in the terminal device 12 operating as the receiving device, the terminal device 12 switches to the transmitting device by transmitting the uplink control channel including the transmission request as described above. In addition, when the terminal device 12 that has operated as the transmission device finishes signal transmission, the terminal device 12 switches to the reception device. Such a group call uses one channel of each base station apparatus 10 when one call occurs. Therefore, when the terminal devices 12 included in the same group are registered in a wide range of base station devices 10, channels corresponding to the number of base station devices 10 are used in one call. The above processing is performed for each group.

  FIG. 1 shows a situation where a group 1 call is made. The second terminal device 12b corresponds to a transmission device. The second terminal apparatus 12b transmits a signal using Ch8 of the second base station apparatus 10b. Group 1 is registered in the first base station apparatus 10a and the third base station apparatus 10c. Therefore, the first terminal apparatus 12a receives a signal using Ch3 of the first base station apparatus 10a, and the third terminal apparatus 12c receives a signal using Ch3 of the third base station apparatus 10c. On the other hand, since group 1 is not registered in the fourth base station apparatus 10d, a signal from the second terminal apparatus 12b is not output to the fourth base station apparatus 10d.

  For example, when the group 1 is registered only in the second base station apparatus 10b, when a call of the group 1 occurs, the transmission apparatus transmits a signal at Ch8 of the second base station apparatus 10b, and the second base station apparatus The receiving device receives the signal at Ch3 of 10b. Therefore, one set of channels of only one base station apparatus 10 is used. When group 1 is registered in two base station apparatuses 10, when a group 1 call occurs, one set of channels is used in each of the two base station apparatuses 10. Therefore, two sets of channels are used. This corresponds to the consumption of the same number of channels as a one-to-one call such as a mobile phone system. Furthermore, when group 1 is registered in three or more base station apparatuses 10, three or more sets of channels are consumed. When all the channels of the third base station apparatus 10c are used for other groups, the third base station apparatus 10c does not make a group 1 call. This corresponds to a miss call or busy state.

  In the busy state, as in this example, in addition to the case where the channel (resource) of the called base station apparatus 10 is not allocated, the channel (resource) of the base station apparatus 10 of the calling second terminal apparatus 12b May not be assigned. In the present embodiment, the channel of the originating base station apparatus 10 (for example, the second base station apparatus 10b) is allocated, the call is successfully made, and the terminating base station apparatus 10 (for example, the third base station 10b) is allocated. When the channel of the station device 10c) is not allocated, the base station device 10 (third base station device 10c) is excluded and the group call is established. That is, only the receiving-side base station device 10 is busy. However, apart from this method, if a channel is not allocated in one or more base station apparatuses 10 on the called side, the call may not be established at all. In that case, all the base station devices 10 related to the call request including the originating base station device 10 may be considered busy. In the present embodiment, a value based on the number of times such a busy state has occurred is referred to as “busy number” or “busy number”.

  FIG. 2 is a sequence diagram illustrating a communication procedure performed by the business use radio system 100. The second terminal apparatus 12b transmits a call request using the uplink control channel (S10). The second base station apparatus 10b notifies the first base station apparatus 10a of a transmission request (S12). The second base station apparatus 10b and the first base station apparatus 10a allocate channels to group 1 (S14, S16). The second base station apparatus 10b transmits the allocation result on the downlink control channel (S18). The second terminal apparatus 12b transmits uplink data to the second base station apparatus 10b (S20). The second base station apparatus 10b transmits data to the first base station apparatus 10a (S22). The first base station apparatus 10a transmits the allocation result on the downlink control channel (S24). The first base station apparatus 10a transmits downlink data to the first terminal apparatus 12a (S26).

  FIG. 3 shows the configuration of the monitoring device 20. The monitoring device 20 includes a reception unit 30, a processing unit 32, a storage unit 34, a selection unit 36, and a display unit 38. The receiving unit 30 is connected to the network 14 in FIG. The receiving unit 30 receives information from each of the plurality of base station devices 10 via the network 14. The information corresponds to the number of busy times that the terminal device 12 included in the group registered in each base station device 10 failed to make a call. The number of busys in which the terminal device 12 has failed in communication is counted as “1” when the originating base station device 10 becomes busy once. When the destination base station apparatus 10 is busy once, the busy number of the destination base station apparatus 10 is counted as “1”. For example, when the second terminal device 12b of the group 1 registered in the second base station device 10b makes a call and the channel of the third base station device 10c is not allocated, the group 1 of the third base station device 10c The busy number is “1”. If at least one of the called-side base station apparatuses 10 is busy, the busy number of the called-side base station apparatus 10 that is busy is set to “1” in the case of busy without establishing the call. ”And the number of base station devices 10 related to the assumption that the call request is successful (the total number of base station devices 10 on the calling side and base station device 10 on the calling side) It may be the busy number of the device 10.

  This is the idea that the larger the number of base station apparatuses 10 related to the call request, the greater the loss due to the failure of the call, and the magnitude of the loss is reflected in the busy number. For example, as in the example illustrated in FIG. 1, the terminal devices of group 1 are registered in the three base station devices 10 of the first base station device 10a to the third base station device 10c, and the second base station device 10b. When the second terminal device 12b of the group 1 registered in the call originates and the channel of the second base station device 10b is allocated, but the channel of the third base station device 10c is not allocated, the first base station The busy number of the group 1 of the device 10a is “0”, the busy number of the second base station device 10b is “3”, and the busy number of the third base station device 10c is “1”. At this time, the number of the base station apparatuses 10 related to the call request is not reflected in the busy number of the originating base station apparatus 10, but the busy number of the called base station apparatus 10 that has become busy. May be reflected. For example, the second terminal device 12b of the group 1 registered in the second base station device 10b makes a call and the channel of the second base station device 10b is allocated, but the first base station device 10a and the third base device When the channel of the station device 10c is not allocated, the busy number of the group 1 of the first base station device 10a is "3", the busy number of the second base station device 10b is "1", and the busy number of the third base station device 10c is The number is “3”. Further, the number of terminal devices 12 related to the case where the call request is assumed to be successful may be reflected in the busy number. For example, a value that increases as the number of terminal devices 12 increases, such as a logarithmic value of the number of terminal devices 12 concerned, or a base station device related to the call request that causes the call failure. It may be 10 busy numbers.

  4A to 4D show the data structure of information received by the receiving unit 30. FIG. FIG. 4A shows information from the first base station apparatus 10a. The number of busys that the terminal device 12 included in each group failed to make a call and the total number of busys that occurred in all the registered groups are shown. The same applies to FIGS. 4B to 4D. Note that these pieces of information are not received from each base station apparatus 10 but are once stored in a database (not shown), and the receiving unit 30 may receive information from the database. Returning to FIG.

  The processing unit 32 outputs the information received by the receiving unit 30 to the storage unit 34. The storage unit 34 stores information from the processing unit 32 as a database. FIG. 5 shows the data structure of the database stored in the storage unit 34. The storage unit 34 stores the groups registered in each base station apparatus 10 and the busy number generated in each registered group in time series. The acquisition time indicates the time when information is acquired. The unit of time is arbitrary, and hour, minute, second, millisecond, microsecond, etc. can be used. However, in this embodiment, for the sake of simplification, “12:30” "(12:30)". Further, this acquisition time may be a so-called “acquisition date and time” including information such as year, month, day, day of the week, etc., and will be referred to as an acquisition time below including the acquisition date and time. The Group registration element indicates the number of the registered group, and the number of registered Group busy occurrences indicates the number of busy occurrences in the registered group between the previous acquisition date and the current acquisition date (for example, 30 minutes). Show. Returning to FIG.

  The selection unit 36 is an interface for allowing the user to select one group to be monitored. The processing unit 32 creates display data (screen data) for selecting a group and displays it on the display unit 38. FIG. 6 shows a group selection screen displayed on the display unit 38. The processing unit 32 acquires a list of groups from the storage unit 34 and creates data for displaying the list on the “Group List”. The user selects a group by moving the group to “Selected Group” using an operation unit such as a keyboard and a mouse. Note that the screen for selecting a group may be configured by radio buttons and pull-down menus. Returning to FIG. As described above, the selection unit 36 selects at least one of the plurality of groups and outputs the selected result to the processing unit 32. A plurality of groups may be arbitrarily combined and selected.

  The processing unit 32 receives the selection result from the selection unit 36. The processing unit 32 calculates the total number of busys corresponding to the group selected by the selection unit 36 from the storage unit 34 for each base station device 10. For example, when group 1 is selected, the busy number of group 1 is calculated for each base station apparatus 10, and when group 1 and group 2 are selected, the busy number of group 1 and the busy number of group 2 are calculated. The total is calculated for each base station apparatus 10. At this time, only one piece of data at a certain acquisition time may be read from the database of the storage unit 34, and the busy number may be calculated based on the read data. Alternatively, the busy number may be calculated based on data at a plurality of acquisition times. When using data at a plurality of acquisition times, for example, the user may specify the range of acquisition times to be used, the most recent predetermined number (for example, 10) of data, or the most recent predetermined time may be used. Data of time (for example, the past 24 hours) may be used. The specific processing unit 32 creates a pie chart with a radius corresponding to the calculated busy number for each base station apparatus 10. For example, the radius of the pie chart increases as the number of busys increases. The processing unit 32 holds a map image in which the position of each base station device 10 is associated, and superimposes a pie chart corresponding to the base station device 10 on the position of the base station device 10. Such a process is performed for each base station apparatus 10. The processing unit 32 causes the display unit 38 to display display data that is a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”). That is, the processing unit 32 creates display data and displays it on the display unit 38.

  In addition, in order to show the busy number which generate | occur | produced in the base station apparatus 10, the pie chart is used here, However, It is not limited to a pie chart. For example, another graph such as a bar graph may be used. At this time, the longer the number of busys generated, the longer the bar is displayed, so that the number of busys generated can be recognized by the user. Further, the circle may have another shape, for example, a square or the like. Also in this case, the number of generated busy is displayed so that the user can recognize it. Further, the map image may be omitted, and only a graph may be generated, or only the number of busys (numbers) generated may be shown. Here, the description is made assuming that the map image is not omitted.

  The display unit 38 displays the map image from the processing unit 32. That is, the display unit 38 displays the busy number generated in the group selected by the selection unit 36 as a pie chart for each base station device 10. FIG. 7 shows a screen displayed on the display unit 38. Here, group 1 is selected. As illustrated, a pie chart with the number of busys occurring in group 1 as a radius is displayed at the position of each base station apparatus 10. As described above, the display unit 38 displays the number of busys generated in at least one group for each base station apparatus 10 based on the information received in the receiving unit 30. It is also possible to connect the display device (not shown) to the monitoring device 20 and display the information on an external display device without including the display unit 38 in the monitoring device 20.

  The configuration of the monitoring device 20 can be realized in terms of hardware by a CPU, memory, or other LSI of an arbitrary computer, and is realized by a program loaded in the memory in terms of software. Describes functional blocks realized through collaboration. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  According to the present embodiment, since the total number of busys generated in a plurality of groups is displayed for each base station apparatus based on the information on the number of busys generated in a group registered in each base station apparatus, The communication status of the group can be grasped collectively. In addition, since one of a plurality of groups is selected and the number of busys occurring in the selected group is displayed for each base station apparatus, the communication status in one group can be easily grasped. In addition, since the number of busy occurrences in the selected group is displayed for each base station device using the graph and the map image, it is possible to easily grasp the busy occurrence distribution status in a specific group and the busy occurrence area of communication between base station devices. Further, it can be seen that the larger the radius of the pie chart is, the more busy is occurring, so the degree of channel resource shortage of the base station apparatus can be estimated. Note that the charge for the group call may be adjusted based on the busy number for each group described in the present embodiment. For example, measures such as reducing the usage fee may be taken for groups with a large number of busys.

(Example 2)
Next, Example 2 will be described. As in the first embodiment, the second embodiment relates to a business wireless system including a monitoring device. The monitoring apparatus according to the first embodiment displays the busy number generated in each base station apparatus with a graph for the selected group. Such a display makes it possible to grasp the communication status at a specific time. In general, the communication status changes with the passage of time. The second embodiment aims to inform the user of changes in the communication status. The monitoring apparatus according to the second embodiment displays the display of the first embodiment while changing the display in time series. The display at that time is, for example, an animation display. The business wireless system 100 and the monitoring device 20 according to the second embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference with Example 1. FIG.

  The receiving unit 30 sequentially receives information from each of the plurality of base station devices 10 via the network 14. For example, the reception unit 30 receives information periodically. Each piece of information received in sequence is the number of busys occurring in the group registered in each base station apparatus 10 and corresponds to the number of busys at a predetermined time. The processing unit 32 receives the selection result from the selection unit 36. The processing unit 32 extracts the number of busys generated in the group selected by the selection unit 36 from the storage unit 34 for each base station device 10. As described above, the processing unit 32 generates a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”). The processing unit 32 displays the generated pie chart on the display unit 38. Further, the processing unit 32 repeatedly executes the above-described processing while changing the acquisition time in FIG. As a result, the processing unit 32 updates the map image with the passage of time. The map image may display and update information on the current date and time in real time, or may display past information in an animated manner in a short time.

  The display unit 38 updates the display of the map image according to the information sequentially received by the reception unit 30. FIGS. 8A and 8B show screens displayed on the display unit 38 according to the second embodiment of the present invention. FIG. 8A shows a map image at a predetermined time (2013/11/27 12:00), which corresponds to FIG. FIG. 8B shows a map image at a time (2013/11/27 13:00) after the time of FIG. When the user specifies a time or a time range, the display unit 38 may display only a map image at the specified time.

  In addition, as illustrated in FIG. 8, a “play” button is arranged on the screen displayed on the display unit 38, and the user presses the “play” button to indicate a change in the number of busys in the past acquisition time. An animation may be played back. Further, the acquisition time (acquisition date and time) of each data may be superimposed and displayed on each frame (each graph) constituting the animation. With such a playback function, it is possible to grasp a busy change occurring in a group registered in each base station apparatus in a very short time compared to the real time, thereby improving user convenience.

  Further, the processing unit 32 may calculate new data by statistical processing using a plurality of data having different acquisition times (acquisition dates and times) and display the new data on the display unit 38. For example, the data for 30 days acquired at the time every 30 minutes (“12:00”, “12:30”, etc.) is stored in the database of the storage unit 34. Then, an average value of 30 data corresponding to a certain time (for example, “12:00”) is calculated. In this way, the average value of the number of busys occurring in the group registered in the base station device 10 calculated every predetermined time within one day (24 hours) may be displayed together with the time information. By calculating such an average value, it is possible to reduce the influence of sudden events, so that it is possible to display the tendency of the busy number with time with time transition with higher accuracy. In addition to the average value, statistical values (such as representative values) such as median, mode, quartile, maximum, and minimum may be calculated, and a graph based on them may be created.

  Further, a statistical value such as an average value may be calculated using data of the same day of the week and the same time. For example, a plurality of data corresponding to “Friday 17:30” may be read from the database of the storage unit 34, and their statistical values may be calculated and displayed. Further, a statistical value may be calculated and used for each elapsed time from the beginning of the month (0: 0 of the day). For example, data for 12 months may be stored in the database, and the statistical value may be calculated from 12 data corresponding to “2 days 12:00”. It should be noted that the arithmetic processing may be performed by regarding data having slightly different acquisition times as the same time. Further, when such a statistical value is calculated and displayed, animation display need not necessarily be performed. For example, a statistical value corresponding to one time (for example, “12:00”) may be calculated from a plurality of data. In this case, since only one image to be displayed is generated, it is displayed as a still image, not an animation.

    According to this embodiment, since the display is updated, it is possible to easily grasp the time change of the busy number. In addition, since the transition of the busy distribution according to the passage of time is shown, it can be easily determined whether the shortage of channel resources is temporary or constantly short.

(Example 3)
Next, Example 3 will be described. The third embodiment relates to a commercial wireless system including a monitoring device as before. In the first and second embodiments, the number of busys occurring in the group registered in each base station apparatus is displayed in a graph for the selected group. When a plurality of groups are selected, the total number of busy groups is displayed. On the other hand, the third embodiment aims to inform the user of the communication status of each group when a plurality of groups are included. The monitoring apparatus according to the third embodiment displays the total number of busys occurring in all groups in a graph instead of the selected group. The monitoring device also displays the ratio of the number of busys for each group set in the base station device. The commercial wireless system 100 according to the third embodiment is the same type as that shown in FIG. Here, it demonstrates centering on the difference from before.

  FIG. 9 shows a configuration of the monitoring device 20 according to the third embodiment of the present invention. The monitoring device 20 includes a receiving unit 30, a processing unit 32, a storage unit 34, and a display unit 38. The processing unit 32 calculates the total number of busys occurring in all groups registered in one base station apparatus 10. Taking FIG. 5 as an example, for the first base station apparatus 10a at the acquisition time “12:00”, “3”, “1”, “0”, “5” indicated in “Registered Group busy occurrences”. The total number of “1” is calculated. The processing unit 32 creates a pie chart with a radius corresponding to the total number. For example, the radius of the pie chart is increased as the total number increases.

  At that time, the pie chart is divided according to the ratio of the number of busy occurrences for each group. For example, a pie chart is divided so as to form a fan with a large central angle for a group with a high percentage of busy occurrences. The processing unit 32 holds the map image in which the position of each base station apparatus 10 is associated with the pie graph corresponding to the base station apparatus 10 at the position of the base station apparatus 10 as before. Superimpose. Such a process is performed for each base station apparatus 10. The processing unit 32 causes the display unit 38 to display a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”). Note that a graph may be created using not only data of one acquisition time but also data of a plurality of acquisition times. For example, using the data corresponding to one day or the most recent predetermined number (such as 12) of acquisition date and time, the total value or average value of the number of busys for each base station device 10 and group is calculated, and based on that value The radius of the pie chart and the center angle of each may be determined.

  The display unit 38 displays the map image from the processing unit 32. That is, the display unit 38 displays, for each base station apparatus 10, the total number of busys generated in the groups registered in the base station apparatus 10 and the ratio of the number of busys generated for each group set in the base station apparatus 10. To do. FIG. 10 shows a screen displayed on the display unit 38. As described above, the total number of busys occurring in the group registered in each base station apparatus 10 is expressed by the size of the radius of the pie chart. The proportion of each group in the total number is expressed as a sector angle. Furthermore, the sector representing each group may be color-coded for each group. In addition, a group that is registered in the base station device 10 and is not busy (a group whose busy number is “0”) may not be displayed in the pie chart at all, and the group name may be displayed in the pie chart. You may make it display related.

  Here, Example 3 will be further described based on FIGS. 11 and 12. FIG. 11 shows an example of a channel configuration in the commercial radio system 100 according to the third embodiment of the present invention. FIG. 11 is the same as FIG. 1, but in order to simplify the display, the downlink control channel, the uplink control channel, and the uplink channel are omitted, and only the downlink channel is shown. Therefore, here, a combination of a downlink channel and an uplink channel is described as one channel. FIG. 12 shows a screen corresponding to the example in FIG.

  In this case, it can be seen that the amount of busy generated in the first base station apparatus 10a and the second base station apparatus 10b is relatively small. Therefore, it can be said that the priority of channel resource enhancement for the first base station apparatus 10a and the second base station apparatus 10b is low.

  On the other hand, in the third base station apparatus 10c and the fourth base station apparatus 10d, there is a lot of busy in group calls. In addition, the third base station apparatus 10c and the fourth base station apparatus 10d are frequently busy in the same group. From this, it can be seen that there is a state where the group call between the base station devices is not established due to a shortage of channel resources, or there is a state where there are too many registered groups for each base station device. By providing the display of FIG. 12 as described above, the user can easily determine the necessity of channel resource enhancement of the base station device 10 and the load situation due to the bias of the group distribution of the terminal devices 12.

  In the screen shown in FIG. 12, information regarding channel resources (for example, the number of channels) possessed by each base station may be displayed in association with the pie chart of each base station. For example, a display such as “first base station apparatus (number of channels = 4)” may be displayed instead of the display of “first base station apparatus” in FIG. Or you may display the information regarding the channel resource which a base station has in the center part of a pie chart. With such a display, the user can more easily determine the shortage and sufficiency of system resources.

  In addition, on the screen shown in FIG. 12, instead of information on channel resources, information on the total number of successful calls of the group call that occurred in each base station device 10 may be displayed. This display makes it possible to determine whether or not group calls are frequently made. If the total number of successful calls is large and the number of busy calls is large, the number of calls with short call times is high. If the total number of successful calls is small but the number of busy is large, it can be estimated that many long-time calls that occupy channel resources are occurring. Note that information regarding the total number of call requests including the busy number may be displayed instead of the total number of successful calls in the group call.

  Further, as in the second embodiment, the display shown in FIG. 12 may be changed in time series. At this time, it may be displayed in real time (real time), or data of past acquisition times may be reproduced in animation at a speed different from the real time.

  According to the present embodiment, since the total number of busys occurring in the group registered in the base station apparatus is displayed, it is easy to select the time zone where calls are concentrated or the target base station apparatus where calls are concentrated. Can grasp. Further, since the ratio of the number of busys occurring for each group set in the base station apparatus is displayed, it is possible to easily grasp which group call tends to fail. Further, since the distribution of the busy numbers of all groups in each base station device is shown, it is possible to estimate the degree of channel resource shortage in units of base station devices.

Example 4
Next, Example 4 will be described. The fourth embodiment relates to a business wireless system including a monitoring device, as before. The fourth embodiment aims to inform the user how busy is occurring in a plurality of base station devices for a group registered in the base station device of interest. As described above, in a group call, communication is performed between base station apparatuses in which the same group is registered. Therefore, regarding the group registered in the target base station apparatus, the path on which communication between the base station apparatuses occurs is recognized by recognizing how much busy is occurring in the plurality of base station apparatuses. . The monitoring apparatus according to the fourth embodiment displays the number of busys generated in a plurality of base station apparatuses for the group registered in the selected base station apparatus. The business wireless system 100 and the monitoring device 20 according to the fourth embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

  The selection unit 36 selects one base station apparatus 10 according to an instruction from the user. Prior to this, the user selects one base station apparatus 10 from among the plurality of base station apparatuses 10 using an operation unit such as a keyboard and a mouse. The selection unit 36 outputs the selected result to the processing unit 32.

  The processing unit 32 receives the selection result from the selection unit 36. The processing unit 32 identifies the group registered in the base station device 10 selected by the selection unit 36 from the storage unit 34. For example, when group 3, group 4, and group 5 are registered in the fourth base station apparatus 10d, if the fourth base station apparatus 10d is selected, the processing unit 32 selects group 3, group 4, and group 5. Identify. Similarly to the third embodiment, the processing unit 32 calculates the total number of busy groups in the corresponding group in the fourth base station apparatus 10d, and creates a pie chart of radii according to the total number. Further, the processing unit 32 divides the pie chart according to the ratio of the number of busys for each group. As a result, a graph similar to that in the third embodiment is generated for the selected base station apparatus 10.

  In addition, the processing unit 32 refers to the database stored in the storage unit 34 to detect another base station device 10 in which the identified group is registered. One or more base station devices 10 may be detected. The processing unit 32 calculates the total number of busy numbers corresponding to the identified group in each detected base station apparatus 10, and creates a pie chart of radii according to the total number. In the above example, the total number of busys included in group 3, group 4, and group 5 is calculated for each detected base station apparatus 10. Further, the processing unit 32 divides the pie chart according to the ratio of the number of busys for each group.

  The processing unit 32 holds the map image in which the position of each base station apparatus 10 is associated with the pie graph corresponding to the base station apparatus 10 at the position of the base station apparatus 10 as before. Superimpose. Such a process is performed for each base station apparatus 10. In addition, the processing unit 32 executes such processing for other base station apparatuses 10. The processing unit 32 causes the display unit 38 to display display data that is a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”).

  The display unit 38 displays the map image from the processing unit 32. That is, the display unit 38 displays, for each base station device 10, the total number of busys corresponding to the group registered in the base station device 10 selected by the selection unit 36 and the busy number ratio for each group. FIG. 13 shows a screen displayed on the display unit 38 according to the fourth embodiment of the present invention. The fourth base station apparatus 10d is selected by the user, and the total number of busys corresponding to each group registered in the selected fourth base station apparatus 10d is indicated by the size of the pie chart. The total number of busys corresponding to the group registered in the fourth base station device 10d among the groups registered in other neighboring base station devices 10 is also indicated by the size of the pie chart. At that time, if the busy of the group registered in the fourth base station apparatus 10d has not occurred, the message is displayed so that it can be understood.

  For example, in the example shown in FIG. 13, the first base station apparatus 10a does not have a busy group common to the fourth base station apparatus 10d, so the center point (dot) of the pie chart is set to the first predetermined point. Display in color (for example, blue). In addition, a base station apparatus in which a group common to the fourth base station apparatus 10d is not registered is displayed so that it can be understood. For example, the center point (dot) of the pie chart is displayed in a second predetermined color (for example, black). In addition, you may display the list etc. of the group number with which busy does not generate | occur | produce in the group registered with the 4th base station apparatus on the map which shows a 4th base station apparatus and another base station apparatus. For example, in the example shown in FIG. 13, group 4 (G1) and group 2 (G2) are registered in the fourth base station apparatus 10d in addition to the illustrated G3 to G5. If no occurs, a display such as “no busy = G1, G2” may be displayed in the vicinity of the pie chart of the fourth base station apparatus. Further, when group 1 and group 2 are registered in the first base station apparatus 10a, “no busy = G1, G2” or the like is displayed near the center point of the pie chart of the first base station apparatus. Good. Furthermore, the sector representing each group may be color-coded for each group.

  According to the present embodiment, since the total number of busys corresponding to the group registered in the selected base station device and the ratio of the busy number for each group are displayed for each base station device, the selected base station device It is easy to find the problem of the group concerning. For example, if a certain base station device (base station X) has a large busy number, the group is registered in another base station device, and the other base station device has a small busy number, It can be determined that resources are insufficient.

(Example 5)
Next, Example 5 will be described. The fifth embodiment corresponds to a modification of the first embodiment and, like the first embodiment, relates to a business wireless system including a monitoring device. The monitoring apparatus according to the first embodiment displays the busy number generated in each base station apparatus with a graph for the selected group. Specifically, the radius of the pie chart is adjusted according to the busy number. The fifth embodiment aims to inform the user of information other than the number of busys generated by a graph. The monitoring apparatus according to the fifth embodiment derives an index indicating the degree of congestion of the base station apparatus, and generates a graph according to the value of the degree of congestion. The business wireless system 100 and the monitoring device 20 according to the fifth embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

  The processing unit 32 receives the selection result from the selection unit 36. The processing unit 32 extracts the number of busys generated in the group selected by the selection unit 36 from the storage unit 34 for each base station device 10. The processing unit 32 derives a ratio between the extracted busy number and the number of channels that can be set in the base station apparatus 10 for each base station apparatus 10. Here, as the ratio, a value obtained by dividing the number of busys occurring in the selected group by the number of channels of the base station apparatus 10 (hereinafter referred to as “index 1”) is derived. This index 1 is the radius of the pie chart, and the larger the index 1, the larger the radius.

  For example, it is assumed that the number of busys occurring in a predetermined group is the same in each of the first base station apparatus 10a and the second base station apparatus 10b. Further, it is assumed that the number of channels that can be set in the first base station apparatus 10a is “10” and the number of channels that can be set in the second base station apparatus 10b is “20”. Under such circumstances, it can be said that the first base station apparatus 10a is more conspicuous in channel resources than the second base station apparatus 10b. Since the index 1 can be said to be an index indicating the degree of congestion of the base station apparatus 10, the processing unit 32 derives an index indicating the degree of congestion of each base station apparatus 10 based on the information received by the receiving unit 30. Yes.

  Further, the processing unit 32 holds a map image in which the position of each base station device 10 is associated with the circle corresponding to the base station device 10 at the position of the base station device 10 as before. Superimpose graphs. Such a process is performed for each base station apparatus 10. The processing unit 32 causes the display unit 38 to display display data that is a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”).

  The display unit 38 displays the map image from the processing unit 32. That is, the display unit 38 displays, for each base station apparatus 10, the index 1 derived by the processing unit 32, that is, the index indicating the degree of congestion, for each group selected by the selection unit 36. The display is the same as in FIG. As in the past, not only the pie chart but also other types of charts such as a bar chart may be used to display the index 1. Also, instead of a graph, the numerical value of index 1 may be displayed as it is. FIG. 14 shows another screen displayed on the display unit 38 according to the fifth embodiment of the present invention. As illustrated, the index 1 for each base station apparatus 10 is shown as a bar graph. As shown in FIG. 14, the graph may be displayed without being superimposed on the map image.

  According to the present embodiment, an index indicating the degree of congestion of each base station apparatus is derived based on information on the number of busys occurring in the group registered in each base station apparatus, and the derived index is assigned to at least one group. On the other hand, since the information is displayed for each base station apparatus, it is possible to grasp the base station apparatus whose degree of congestion increases. In addition, since the ratio between the number of busys generated in the selected group and the number of channels that can be set in the base station apparatus is derived and displayed for each base station apparatus, it is possible to identify a base station apparatus in which the channel is likely to be busy. Further, by displaying the index 1, it is possible to easily grasp the necessity of facility enhancement of the base station device.

(Example 6)
Next, Example 6 will be described. The sixth embodiment corresponds to a combination of the fifth embodiment and the second embodiment, and relates to a commercial wireless system including a monitoring device as before. The monitoring apparatus in the fifth embodiment displays an index 1 indicating the degree of congestion of the base station apparatus with a graph for the selected group. The monitoring apparatus according to the sixth embodiment displays the display of the fifth embodiment while changing the display in time series. The display at that time is, for example, an animation display. The business wireless system 100 and the monitoring device 20 according to the sixth embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

  The processing unit 32 receives the selection result from the selection unit 36. The processing unit 32 extracts the number of busys generated in the group selected by the selection unit 36 from the storage unit 34 for each base station device 10. As described above, the processing unit 32 derives the index 1 to generate a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”). The processing unit 32 displays the generated pie chart on the display unit 38. Further, the processing unit 32 repeatedly executes the above-described processing while changing the acquisition time in FIG. As a result, the processing unit 32 sequentially derives the index 1 according to the information sequentially received by the receiving unit 30. The display unit 38 updates the display of the map image with the index 1 sequentially derived by the processing unit 32. The display here is the same as in FIGS. 8A to 8B. Similar to the second embodiment, the map image may display and update information on the current date and time in real time, or may display past information in an animation in a short time. Further, the processing unit 32 associates the acquisition time with the derived index 1 and stores it in the database of the storage unit 34. When displaying a map image or the like, the index 1 of the predetermined acquisition time is displayed from the database of the storage unit 34. You may make it read. Further, as described in the second embodiment, a statistical value may be calculated using a plurality of data having different acquisition times (acquisition dates and times), and the index 1 may be calculated based on the statistical values.

  According to the present embodiment, the time change of the index 1 can be easily grasped.

(Example 7)
Next, Example 7 will be described. The seventh embodiment corresponds to a modification of the third embodiment, and relates to a commercial wireless system including a monitoring device, as before. The monitoring apparatus according to the third embodiment displays the total number of busys occurring in all groups in a graph and also displays the ratio of the number of busys for each group set in the base station apparatus. The purpose of the seventh embodiment is to inform the user of information other than the total number of busys using a graph. The monitoring apparatus according to the seventh embodiment derives an index indicating the degree of congestion of the base station apparatus, and generates a graph according to the value of the degree of congestion. The business wireless system 100 and the monitoring device 20 according to the seventh embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

  The processing unit 32 derives a ratio between the number of busys generated in a group registered in one base station apparatus 10 and the number of channels that can be set in the base station apparatus 10. Here, as a ratio, a value (hereinafter referred to as “index 2”) obtained by dividing the total number of busys generated in the group by the number of channels of the base station apparatus 10 is derived in each base station apparatus 10. This index 2 is the radius of the pie chart. The larger the index 2, the larger the radius. Further, the pie chart is divided according to the ratio of the number of busys for each group. Further, the processing unit 32 holds a map image in which the position of each base station device 10 is associated with the circle corresponding to the base station device 10 at the position of the base station device 10 as before. Superimpose graphs. Such a process is performed for each base station apparatus 10. The processing unit 32 causes the display unit 38 to display display data that is a map image on which a pie chart is superimposed (hereinafter also referred to as “map image”).

  The display unit 38 displays the map image from the processing unit 32. That is, the display unit 38 displays the index 2 derived by the processing unit 32 for each base station device 10 and displays the ratio of the number of busys for each group set in the base station device 10 for each base station device 10. To do. The display is the same as in FIG. It can be said that the base station apparatus 10 having a larger index 2 value and a larger number of busy groups has a higher necessity for equipment enhancement of the base station apparatus 10. This index 2 can also be said to be an index indicating the degree of congestion of the base station device 10. Moreover, you may display other types of graphs, such as a bar graph, instead of a pie chart. For example, the index 2 may be the height of the bar graph, and the bar graph may be divided and displayed according to the number of busys for each group. Furthermore, the ratio of the number of busys for each group set in the base station device 10 may not be displayed.

  According to the present embodiment, the ratio between the total number of busys generated in the group registered in the base station apparatus and the number of channels that can be set in the base station apparatus is derived and displayed for each base station apparatus. Easily grasp the necessity of station equipment enhancement. In addition, since the ratio of the number of busys for each group set in the base station apparatus is displayed for each base station apparatus, it is possible to identify a base station apparatus that is frequently congested and easily congested.

(Example 8)
Next, Example 8 will be described. The eighth embodiment corresponds to a modification of the seventh embodiment. The index of Example 8 is different from index 2. The business wireless system 100 and the monitoring device 20 according to the eighth embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

  The processing unit 32 derives a ratio between the total number of busys generated in one base station apparatus 10 and the number of groups registered in the base station apparatus 10. Here, as the ratio, a value (hereinafter referred to as “index 3”) obtained by dividing the total number of busys generated in each base station apparatus 10 by the number of groups registered in the base station apparatus 10 is derived. This index 3 is the radius of the pie chart or the height of the bar chart. Note that the pie chart or the bar chart may be divided or not divided according to the ratio of the number of busys for each group.

  Generally, as the number of registered groups increases, the number of busys tends to increase. However, there are cases where the number of busys is large even though the number of groups is small. For example, when the number of groups registered in a base station is larger than the number of channels and the call pattern of the group is much higher than the average group, the number of calls per unit time is very high. This is the case when the call time is very long. It can be said that the base station apparatus 10 having a larger value of the index 3 is more likely to include such a special group. In such a case, it is necessary to increase the resources of the base station or request the registered group to bring the call pattern closer to the average. For example, the busy number of the first base station apparatus 10a is “10”, the registered group number is “5”, the busy number of the second base station apparatus 10b is “20”, and the registered group It is assumed that the number is “2”. In this case, the index 3 of the first base station apparatus 10a is “2”, and the index 3 of the second base station apparatus 10b is “10”. Compared to the second base station apparatus 10b, the first base station apparatus 10a is judged to have a higher necessity for facility enhancement and a need for a call pattern change request for the group. Such an index 3 can also be said to be an index indicating the degree of congestion of the base station apparatus 10.

  According to the present embodiment, since the ratio between the total number of busys generated in the base station device and the number of groups registered in the base station device is derived and displayed for each base station device, the equipment of the base station device is enhanced. It is possible to easily grasp the necessity of calling and a request for changing the call pattern to the group.

Example 9
Next, Example 9 will be described. The ninth embodiment corresponds to a modification of the seventh and eighth embodiments. The index of Example 8 is different from index 2 and index 3. The business wireless system 100 and the monitoring device 20 according to the ninth embodiment are the same type as those in FIGS. Here, it demonstrates centering on the difference from before.

The processing unit 32 determines the ratio between the total number of busys generated in each group registered in the base station apparatus 10 and the number of channels that can be set in the base station apparatus 10, the number of groups registered in the base station apparatus 10, and the base An index is derived based on the ratio to the number of channels that can be set in the station apparatus 10. Here, “index 4” is derived according to equation (1) or equation (2). In Equation (1) and Equation (2), the number of channels of a predetermined base station device 10 is “C”, the number of groups registered in the base station device 10 is “G”, and the busy number of group j is D [j] and index 4 are Z [4]. Formula (1) is shown as follows.

  In Expression (1), α1 and α2 are constants that satisfy α1> 0 and α2> 0, and λ1 and λ2 are constants that satisfy λ1> 0 and λ2> 0. N indicates the number of all groups. Equation (1) can be said to be a weighted average of two terms, with α1 and α2 as weighting factors. As α2 is larger than α1, the influence of the group number G in the index 4 increases. Further, it is possible to set λ1 = λ2 = 1 and not to perform the power operation.

式（２）において、βは、β＞０を満たす定数であり、μ１、μ２は、μ１＞０、μ２＞０を満たす定数である。また、μ１＝μ２＝１としてべき乗の演算を行わないようにしてもよい。式（１）または式（２）にしたがって算出される指標４は、基地局装置１０のチャネル数Ｃが小さいほど、かつグループ数Ｇが大きいほど、かつ各グループのビジー数の総和が大きいほど、大きな値になる。指標４が大きくなるほど、基地局装置１０の設備増強の必要性が高いといえる。このような指標４も、基地局装置１０の混雑度を示す指標ともいえる。この指標４を円グラフの半径あるいは棒グラフの高さに対応させて、基地局装置ごとに円グラフまたは棒グラフを表示する。なお、グループごとのビジーの数の割合に応じて、円グラフまたは棒グラフが分割されてもよいし、分割されなくてもよい。 Formula (2) is shown as follows.

In Expression (2), β is a constant that satisfies β> 0, and μ1 and μ2 are constants that satisfy μ1> 0 and μ2> 0. Further, power calculation may not be performed with μ1 = μ2 = 1. The index 4 calculated according to the formula (1) or the formula (2) is such that the smaller the channel number C of the base station apparatus 10 is, the larger the group number G is, and the larger the total sum of the busy numbers of each group is, Great value. It can be said that the larger the index 4, the higher the need for equipment enhancement of the base station apparatus 10. Such an index 4 can also be said to be an index indicating the degree of congestion of the base station apparatus 10. The index 4 is made to correspond to the radius of the pie graph or the height of the bar graph, and the pie graph or bar graph is displayed for each base station apparatus. Note that the pie chart or the bar chart may be divided or not divided according to the ratio of the number of busys for each group.

  According to the present embodiment, since the index 4 is displayed for each base station apparatus, it is possible to accurately grasp the necessity for equipment enhancement of the base station apparatus.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  The second embodiment may be combined with the third embodiment of the present invention. In this case, the display of Example 3 is updated with time. According to this modification, it can be determined whether the channel resource shortage of the entire base station apparatus is temporary or stationary.

You may combine Example 2 with Example 4 of this invention. In this case, the display of Example 4 is updated with time. According to this modification, it is possible to grasp whether or not the change in busy status in a plurality of base station devices transitions with time for a group registered in the selected base station device. Note that a group registered in the selected base station apparatus at the time of selection may be specified, and the change in the busy status of the specified group over time may be displayed.
