That is, the accommodation design is performed. And based on this accommodation design result, setting work for the accommodation change of several base stations accommodated in the existing relay device is performed for the newly added relay device, and further, along with this accommodation change The base station accommodation change setting operation is also performed for the existing relay apparatus.

  As described above, expansion of the relay device requires accommodation design work and accommodation change setting work, and this work man-hour is enormous. For this reason, the present situation is that the efficiency of these operations is desired.

  Therefore, Patent Document 1 below discloses a technique for improving the efficiency of the accommodation change setting operation by setting the accommodation change by inputting an accommodation change command to each relay device or the like. .

  Next, the operation of the wireless communication system in the present embodiment will be described according to the sequence diagram shown in FIG. Here, as shown in FIG. 1, a case will be described in which a base station a to e and relay apparatuses A and B are already in operation and a relay apparatus C is newly added here.

  As shown in FIGS. 1 and 7, the communication load acquisition unit 113 of the management apparatus 100 periodically communicates with all the base stations a to e via the communication control unit 111 as described later. A load notification is requested (S101). At this time, the communication control unit 111 acquires the communication address of each base station a to e from the system configuration information table 131 shown in FIGS. 4 and 7, and transmits a communication load notification request to each base station a to e. . In FIG. 7, the configuration of the system configuration information table 131 is simplified, and the communication addresses of the relay device and the accommodating base station are also simplified. Further, in FIG. 7, the configuration of the communication load information table 132 is also simplified.

  When the communication load monitoring unit 312 of each of the base stations a to e receives the communication load notification request from the management apparatus 100 via the communication control unit 311, the communication load monitoring unit 312 stores the communication load monitoring unit 312 in the communication load storage unit 322 (FIG. 6). The number of belonging terminals is transmitted as a communication load to the management apparatus 100 (S301). The call control unit 312 of each base station a to e stores information on the wireless communication terminal 5 in the connection terminal information table 321 in the course of communication connection processing between the wireless communication terminal 5 and other terminals, and performs this wireless communication. When communication between the terminal 5 and another terminal is completed, the previously stored information is deleted. The communication load monitoring unit 312 monitors the connection terminal information table 321, and stores the number of records in the connection information table 321, that is, the number of the wireless communication terminals 5 that belonged or are in the process of belonging to the communication load storage unit 322. In response to a request from the management device 100, the communication load monitoring unit 312 transmits the number of wireless communication terminals 5 stored in the communication load storage unit 322 as a communication load to the management device 100 as described above. To do.

  Here, it is assumed that the relay apparatus C is installed. When the power of the relay device C is turned on (S201), the relay device C becomes communicable and is in an operation state in which call control is possible, the own device information notification unit 215 installs the relay device C or Prior to that, the management apparatus 100 is notified of the ID and communication address of the own apparatus C via the communication control unit 211 with reference to the own apparatus information table 222 stored in the work memory 220 (S202).

  Upon receipt of this notification via the communication control unit 111, the accommodation design unit 114 of the management device 100 adds a new record to the system configuration information table 131 as shown in FIG. Stores the ID and communication address of the newly installed relay apparatus C. In this embodiment, information sent from the relay device C is stored in the system configuration information table 131 as information on the newly installed relay device C. Instead, the input device 151 ( The ID and the like of the relay device C input from FIG. 1) may be stored in the system configuration information table 131.

  As shown in FIGS. 1 and 7, the operation state grasping unit 112 of the management apparatus 100 is configured to connect all the relay apparatuses A to C whose communication addresses are stored in the system configuration information table 131 via the communication control unit 111. As will be described later, the base stations a to e are periodically requested to notify the state information (S102).

  When the operation state management units 213 and 313 of all the relay devices A to C and the base stations a to e receive this notification via the communication control units 211 and 311, they determine whether or not the own device is in an operation state. Then, the management apparatus 100 is notified via the communication control units 211 and 311 (S204, S304). The operation state management units 213 and 313 of the relay device and the base station always know whether or not the own device is in an operation state capable of executing the function required for the own device, and this grasped state To the management apparatus 100.

  As shown in FIGS. 1 and 7, the operation state grasping unit 112 of the management device 100 receives state information notifications from all the relay devices A to C and the base stations a to e via the communication control unit 111. Based on this notification, the communication load information table 132 is updated. In this case, since the operation state grasping unit 111 has newly received a state information notification from the relay apparatus C indicating that it is in an operation state, a new record is provided in the communication load information table 132, and this relay is included in this record. The ID “C” of the device C is stored. Subsequently, the operating state grasping unit 112 determines whether or not the number of records in the communication load information table 132, in other words, the number of operating relay devices has changed (S104). When the operation state grasping unit 112 determines that the number of operating relay devices has changed, the operation state grasping unit 112 instructs the accommodation design unit 114 to execute the accommodation design.

  When the accommodation design unit 114 is activated in response to this instruction, the accommodation design is executed as described later (S105), and the system configuration information table 131 and the communication load information table 132 are changed based on the accommodation design result. (S106). Specifically, the relationship between the relay device and the base station accommodated in the relay device in each table 131, 132 is changed. Then, the accommodation design unit 114 instructs the accommodation change instruction unit 115 to execute the accommodation change instruction.

  When the accommodation change instructing unit 115 receives this instruction and starts up, as will be described later, with reference to the changed system configuration information table 131, the ID of the base station to be accommodated for each of the relay devices A to C Then, a change instruction including the communication address is transmitted, and a change instruction including the ID and communication address of the accommodating relay apparatus is transmitted to each of the base stations a to e (S107).

  When the accommodation base station changing unit 214 of each of the relay apparatuses A to C receives this change instruction via the communication control unit 211, the accommodation base station information according to the ID of the accommodation base station included in the change instruction is received. The table 221 is changed (S208). The accommodation base station changing unit 214 of the newly installed relay apparatus C newly registers the accommodation base station ID and the like in the accommodation base station information table 221 (S208a). When the accommodation base station change table 214 changes the accommodation base station information table 221, the accommodation base station change unit 214 transmits a change completion notification to the management apparatus 100 via the communication control unit 211 (S209).

  Further, when the accommodation destination relay device changing unit 314 of each base station a to e receives this change instruction via the communication control unit 311, the accommodation destination relay device changing unit 314 follows the ID of the accommodation destination relay device included in the change instruction. Then, the relay device information table 323 is changed (S308). The accommodation relay device changing unit 314 changes the relay device information table 232 and transmits a change completion notification to the management device 100 (S309).

  As described above, in this embodiment, since the management apparatus 100 executes the accommodation design and the accommodation change instruction associated with the change in the number of relay apparatuses 200, it is possible to improve the efficiency of work associated with this change in the number of relay apparatuses 200.

  Next, the communication load acquisition process of each base station 300 by the management apparatus 100 will be described according to the flowchart shown in FIG.

  When the communication load acquisition unit 113 of the management apparatus 100 reaches the collection timing of the communication load (S110), the communication load is transmitted to all the base stations 300 stored in the system configuration information table 131 via the communication control unit 111. (S111, (S101 in FIG. 8)). The collection timing of the communication load is set every predetermined interval (for example, 1 hour), and the communication load acquisition unit 113 determines whether or not the collection timing has come depending on whether or not this interval has passed. To do.

  In response to this communication load notification request, each base station 300 returns a notification of the communication load of its own device to the management device 100 as described above with reference to FIG. When receiving the communication load notification via the communication control unit 111 (S112), the communication load acquisition unit 113 of the management apparatus 100 updates the communication load information table 132 based on the notification (S113). End load acquisition.

  Upon receiving the communication load notification from each base station 300, the communication load acquisition unit 113 displays the communication load (the number of base stations belonging) included in this notification in the record of the corresponding base station in the communication load information table 132. Stored in the latest communication load area 132c. Furthermore, the communication load acquisition unit 113 obtains an average value of communication loads from the past to the present time, and stores this in the average communication load area 132d.

  In this embodiment, each base station 300 is notified of the communication load of each base station 300. However, since each relay device 200 can grasp the communication load of the accommodating base station 300, in this case May request each relay device 200 to notify the communication load of each base station 300.

  Next, according to the flowchart shown in FIG. 10, the operation status grasping process of each relay device 200 and each base station 300 by the management device 100 will be described.

  The operation state grasping unit 112 of the management apparatus 100 always monitors whether the communication control unit 111 has received a state information notification from the outside (S120). When the communication control unit 111 receives a state information notification from the outside, the operation state grasping unit 112 proceeds to step 124 and updates the communication load information table 132 according to the state information notification.

  Further, when the communication control unit 111 has not received the status information notification from the outside, the operation status grasping unit 112 waits until the status information collection timing comes (S121), and at the collection timing, the system configuration information table 131 stores the status information notification. A status information notification request is transmitted to all the stored relay devices 200 and all base stations 300 via the communication control unit 111 (S122, (S102 in FIG. 8)). The collection timing of the communication load is set every predetermined interval (for example, one day), and the operating state grasping unit 112 determines whether or not the collection timing has come depending on whether or not this interval has passed. To do.

  In response to this communication load notification request, each relay device 200 and each base station 300 returns a notification of the operation state of the own device to the management device 100 as described above with reference to FIG. When receiving the notification of the operating state via the communication control unit 111 (S123), the operating state grasping unit 112 of the management apparatus 100 updates the communication load information table 132 based on the notification (S124).

  In the present embodiment, whether or not the communication control unit 111 always receives the status information notification (S120) is because the operation of the relay device 200 or the base station 300 is stopped in advance or the operation is stopped. This is to grasp immediately after the stop. As described above, the operation state grasping unit 112 periodically transmits a state information notification request (S122), and receives state information from each device in response to this request (S123). If the status information is not returned from the request transmission destination in response to this request, the operating state grasping unit 112 indicates that the request transmission destination is no longer in operation, in other words, the request transmission destination device is removed. It is possible to grasp that a failure or failure has occurred. However, if it is understood that the device has been removed by such a method, and then the accommodation design is performed, the accommodation design is newly performed after the removed device does not function, and the system is configured. The time lag until each device 200, 300 is changed is increased. Therefore, in the present embodiment, it is always monitored whether or not the communication control unit 111 has received the status information notification (S120), and the stoppage of the relay device 200 or the base station 300 can be grasped in advance or immediately after the stoppage. I am doing so. The transmission source of the state information in this case may be the relay device 200 or the base station 300 that stops operation, but may also be a terminal of an operator of this system who knows the operation stop by some means.

  When the operation state grasping unit 112 updates the communication load information table 132 based on the notification of the operation state (S124), if the notification is a notification from a device that has newly entered the operation state, the operation state grasping unit 112 If a record for this device is provided in the load information table 132, the ID of this device is stored in this record, and this notification is a notification that the operation is stopped, the communication load information table 132 reads Delete the record of the operating device. Although the record of the non-operating device is deleted here, it is not necessary to delete the record of the non-operating device if the active device and the non-operating device can be distinguished.

  When the communication load information table 132 is updated, the operating state grasping unit 112 refers to the communication load information table 132 and determines whether or not the number of active relay devices 200 has changed (S125 (in FIG. 8). S104)). If there is no change in the number of relay apparatuses 200 in operation, this operation state grasping process is terminated. Further, if there is a change in the number of relay devices 200 in operation, the accommodation design unit 114 is instructed to execute the accommodation design (S126), and the operation state grasping process is terminated.

  Next, the accommodation design process by the management apparatus 100 will be described according to the flowchart shown in FIG.

  When the accommodation design unit 114 of the management apparatus 100 is instructed to execute the accommodation design from the operation state grasping unit 112 (S130), the accommodation design unit 114 acquires data of the communication load information table 132 and expands this copy on the memory 120 ( S131). Next, among the data of the communication load information table 132 developed on the memory 120, the base station IDs are rearranged in order of increasing average communication load (S132). Specifically, the average communication load of the base station a is “24”, the average communication load of the base station b is “14”, the average communication load of the base station c is “28”, and the average communication load of the base station d is “ 19 ”, when the average communication load of the base station e is“ 8 ”, the base station IDs are arranged in the order of e → b → d → a → c as developed in the memory 120 of FIG.

  Next, the accommodation design unit 114 sequentially assigns one unit from the upper base station to each active relay device A to C (S133). Specifically, as developed on the memory 120 of FIG. 7, the relay device A for the base station e, the relay device B for the base station b, the relay device C for the base station d, the base Relay device A is assigned to station a, and relay device B is assigned to base station c.

  Next, the accommodation design unit 114 changes the accommodation relationship between the relay device 200 and the base station 300 in the communication load information table 132 based on the allocation result in step 133 (S134 (S106 in FIG. 8)). That is, as in the changed communication load information table 132 in FIG. 7, the relay device A accommodates the base stations e and a, the relay device B accommodates the base stations b and c, and the newly installed relay The accommodation relationship is changed so that the device C accommodates the base station d. In the communication load information table 132, the communication load and average communication load for each base station a to e remain in the original relationship.

  Next, the accommodation design unit 114 changes the accommodation relationship between the relay device 200 and the base station 300 in the system configuration information table 131 as well as the communication load information table 132 based on the allocation result in step 133. (S135 (S106 in FIG. 8)). Although the communication load information table 132 is changed first here, it goes without saying that the system configuration information table 131 may be changed first.

  When the accommodation design unit 114 changes the tables 131 and 132, it instructs the accommodation change instruction unit 115 to execute a change instruction to the devices 200 and 300 (S126), and ends the accommodation design process.

  In the above description, the base station IDs are rearranged in order of increasing average communication load (S132), and one unit from the upper base station is sequentially assigned to each active relay device (S133). The station IDs may be rearranged in descending order of the average communication load, and then one station from the upper base station may be sequentially allocated to each active relay device. That is, each base station may be allocated by any method as long as each base station can be allocated to each relay apparatus so that the communication load of each active relay apparatus approaches equally.

  In the above description, the number of terminals belonging to each base station is used as the communication load of each base station. However, any of the following parameters 1) to 3) is applicable as long as the parameter corresponds to the communication load of each base station. May be used.
