Description

  The present invention relates to a management apparatus and a management method.

  In the wireless communication network, a plurality of stations including an upper station (for example, RNC: Radio Network Controller) and a lower station (for example, a base station) are arranged. In the wireless network device, a plurality of stations may be newly added. Each station has various configuration items (for example, an installation position, a sector, a carrier, and a frequency in a wireless communication network). Therefore, when newly adding a plurality of stations, an update data group related to the configuration items of the plurality of extension stations is input to the management apparatus in the wireless communication network, and the management apparatus reflects the update data group in the database. For example, conventionally, the management apparatus inputs a plurality of “first data units”. Each first data unit is, for example, an independent data file. The plurality of first data units respectively correspond to a plurality of configuration items of the station. Each first data unit includes a first update data group related to configuration items for a plurality of stations. Then, the management device inputs the plurality of first data units in order, and advances the update process in that order.

  Such an update process is expected to be frequently executed when a new system such as a 3GPP LTE (3rd Generation Partnership Project Long Term Evolution) system is introduced. In addition, since many small cells are introduced in the LTE system, such an update process is expected to be executed more frequently. Therefore, the update processing time is expected to be prolonged, and it is desired to shorten the update processing time.

JP-A-6-252900 JP 2004-274608 A

  By the way, generally, in order to shorten the processing time, it is conceivable to perform processing by a plurality of processors (that is, multi-core).

  However, there is a dependency relationship between the configuration items, and an error may occur if the second configuration item is processed before the first configuration item. Therefore, even if a plurality of processors are prepared, processing is eventually performed by one processor, resulting in a long update processing time.

  The disclosed technology has been made in view of the above, and an object thereof is to provide a management device and a management method capable of reducing the update processing time.

  In the disclosed aspect, a management device that manages information on each station in a wireless communication network includes an acquisition unit, a creation unit, and an allocation unit. The acquisition unit acquires a plurality of first data units respectively corresponding to a plurality of configuration items of a station and each first data unit includes a first update data group related to the configuration items for the plurality of stations. . The creation unit includes, from the plurality of acquired first data units, a second update data group corresponding to the plurality of stations and each second data unit relating to the plurality of configuration items for one station. A plurality of second data units are created, and in each of the second data units, the second update data group is arranged in an order based on the dependency of the plurality of configuration items. The assigning unit assigns each of the created second data units to any of a plurality of processors that execute data update of a database.

  According to the disclosed aspect, the update processing time can be shortened.

  Hereinafter, embodiments of a management device and a management method disclosed in the present application will be described in detail with reference to the drawings. In addition, the management apparatus and management method which this application discloses are not limited by this embodiment. Moreover, the same code | symbol is attached | subjected to the structure which has the same function in embodiment, and the overlapping description is abbreviate | omitted.

[Example 1]
[Outline of communication system]
FIG. 1 is a diagram illustrating an example of a communication system according to the first embodiment. In FIG. 1, the communication system 1 includes a management apparatus 10, control stations 30-1 and 30-1, and base stations 50-1 to 50-5. That is, the communication system 1 is a wireless communication network. Here, the number of control stations 30 is two and the number of base stations 50 is five, but the number is not limited to this. The control station 30 is, for example, an RNC. In FIG. 1, base stations 50-1 to 50-3 are arranged under the control station 30-1, and base stations 50-4 and 5 are arranged under the control station 30-2.

  Here, it is assumed that the control station 30-2 and the base stations 50-4 and 5 already exist, and the control station 30-1 and the base stations 50-1 to 50-3 are newly added.

  At this time, in the management apparatus 10, “update processing” of the configuration information (configuration item) of each station in the communication system 1 is executed.

  For example, first, the management apparatus 10 includes a plurality of first update data groups each corresponding to a “plurality of configuration items” of a station and each first data unit includes configuration items for a plurality of stations. The first data unit is input. The first data unit is, for example, an independent data file. The “plurality of configuration items” includes, for example, an installation position, a sector, a carrier, and a frequency in the wireless communication network.

  Then, the management device 10 includes a second update data group related to a plurality of configuration items for one station, each corresponding to a plurality of stations from the plurality of acquired first data units, A plurality of “second data units” are created. At this time, the management apparatus 10 arranges the second update data group in each second data unit in the order based on the “dependency relationship” of the plurality of configuration items. For example, the management apparatus 10 arranges the second update data group in each second data unit in the order from the higher order to the lower order. Here, the “dependency relationship” is an upper-lower relationship between configuration items. For example, the installation position in the wireless communication network is higher, and the mounting information (that is, sector information, carrier information, frequency information, etc.) is lower. Further, when sector information and carrier information are compared with frequency information, sector information and carrier information are higher and frequency information is lower.

  That is, the “first data unit” is a data unit grouped in units of configuration items, while the “second data unit” is a data unit grouped in station units.

  Then, the management apparatus 10 allocates the plurality of second data units in units of second data units to any of the plurality of processors that execute data update of the database.

  In the management apparatus 10, the plurality of processors reflect the plurality of second data units in the database. The database holds a plurality of second data units independently for each second database.

  Then, the management apparatus 10 transmits a plurality of second data units (for example, a plurality of station data files) held in the database to corresponding stations (for example, the control station 30 and the base station 50). Thereby, the information of the station data file is reflected on each station.

  As described above, the management apparatus 10 includes a plurality of first data units in which update data is collected in units of configuration items from a plurality of first data units in which update data is collected in units of configuration items. The second data unit is created. Then, the management apparatus 10 allocates the plurality of second data units in units of second data units to any of the plurality of processors that execute data update of the database.

  Thereby, since a plurality of second data units can be reflected in the database using a plurality of processors, the update processing time can be shortened.

  In each second data unit, the second update data group is arranged in the order based on the dependency relationship between the plurality of configuration items.

  Thereby, since the second update data group can be arranged in an order that matches the processing order in the update process of each processor, the occurrence of an error can be prevented, and as a result, the update process time can be shortened.

[Configuration example of management device]
FIG. 2 is a block diagram illustrating an example of a management apparatus according to the first embodiment. In FIG. 2, the management apparatus 10 includes an acquisition unit 11, a creation unit 12, a processing time calculation unit 13, storage units 14 and 18, a scheduler 15, a buffer 16, processors 17-1 and 2, and a processing time. A management unit 19 and a distribution unit 20 are included. Although the number of processors 17 is two here, this number is not particularly limited to two as long as it is plural.

  The acquisition unit 11 acquires the plurality of first data units. The acquisition timing is, for example, when a change occurs in the configuration of the communication system. Then, the acquisition unit 11 outputs the acquired plurality of first data units to the creation unit 12.

  The creation unit 12 includes a second update data group related to a plurality of configuration items for each of the plurality of first data units acquired by the acquisition unit 11 and corresponding to each of the plurality of stations. A plurality of second data units including are created. At this time, the management apparatus 10 arranges the second update data group in each second data unit in the order based on the dependency of the plurality of configuration items.

  For example, the creating unit 12 performs “analysis processing” for each first data unit from the plurality of first data units. That is, the creating unit 12 analyzes the update data (that is, the entry) of the first update data group included in one first data unit one by one. In this analysis, a station corresponding to each update data is specified. Then, the creation unit 12 associates a plurality of update data with station identification information and configuration items corresponding to each update data. Then, the creation unit 12 creates the plurality of second data units by arranging a plurality of update data associated with the same station identification information in an order according to the dependency relationship.

  In addition, the creation unit 12 outputs station identification information and configuration items corresponding to each update data to the processing time calculation unit 13.

  The creating unit 12 outputs the created second data units to the buffer 16.

  The processing time calculation unit 13 calculates the time required for database update processing (hereinafter, may be referred to as “first predicted time”) for each second data unit.

  For example, the processing time calculation unit 13 determines the number of combinations of stations and configuration items based on the station identification information and configuration items received from the creation unit 12, that is, the number of entries for each configuration item in each second data unit. Count. Then, the processing time calculation unit 13 is based on each count value and the update processing required time for each configuration item stored in the storage unit 14 (hereinafter sometimes referred to as “second predicted time”). The first predicted time for each second data unit is calculated. That is, the processing time calculation unit 13 multiplies the count value of each configuration item in a certain second data unit by the second prediction time corresponding to each configuration item, and adds all the multiplication results to obtain the first. A first predicted time for two data units is calculated.

  Then, the processing time calculation unit 13 associates the combination of the station and the configuration item with the count value for each combination and stores it in the “management table” stored in the storage unit 14. Further, the processing time calculation unit 13 associates the multiplication result with the first prediction time and stores the result in the “management table”.

  The storage unit 14 stores the “management table”. The management table first includes information related to the dependency relationship. The management table stores a combination of the station and the configuration item and a count value for each combination in association with each other. In addition, the management table stores the multiplication result and the first predicted time in association with each other.

  FIG. 3 is a diagram illustrating an example of a management table according to the first embodiment. The “input order” in FIG. 3 corresponds to the above-described dependency relationship. “Grouping information” in FIG. 3 corresponds to the station identification information. In addition, “record 1-5 average” of “estimated input time” in FIG. 3 corresponds to the second predicted time. In addition, “management number” in FIG. 3 corresponds to the combination of the station and the configuration item, and “number of rows” corresponds to the count value. In addition, “predicted time” in FIG. 3 corresponds to the multiplication result and the first predicted time. That is, when attention is paid to the station A in FIG. 3, the prediction times “1”, “2.5”, and “15” correspond to the multiplication results, respectively, and the prediction time “18.5” corresponds to the first prediction time. To do. Note that “records 1 to 5” in FIG. 3 store the latest five times of the time actually taken for the update processing for one entry. The “records 1 to 5” and the “average of records 1 to 5” are managed by the processing time management unit 19.

  The scheduler 15 assigns each of the plurality of second data units created by the creation unit 12 to one of the processors 17-1 and 17-2. Then, the scheduler 15 outputs an “output command signal” to the buffer 16 based on the allocation result. The output command signal includes identification information of the second data unit that is the output target and identification information of the processor 17 that is the output destination.

  For example, the scheduler 15 assigns each of the plurality of second data units to one of the processors 17-1 and 2 in order from the longest first prediction time based on the “management table”. .

  The buffer 16 temporarily holds a plurality of second data units created by the creation unit 12. Then, the buffer 16 outputs the second data unit indicated by the output command signal received from the scheduler 15 to the processor 17 indicated by the output command signal.

  Each of the processors 17-1, 2 reflects the second data unit received from the buffer 16 in the database stored in the storage unit 18. Each of the processors 17-1 and 17-2 outputs a “completion notification signal” to the scheduler 15 every time the reflection process (that is, the update process) of one second data unit is completed. Using this completion notification signal as a trigger, the scheduler 15 outputs the next output command signal.

  Each of the processors 17-1 and 17-2 reports the time taken for the update process of each update data to the processing time management unit 19.

  The storage unit 18 stores the above database. Note that the storage unit 14 and the storage unit 18 may be configured as one storage unit.

  The processing time management unit 19 calculates the second predicted time using the time reported from the processors 17-1 and 17-2.

  For example, the processing time management unit 19 updates “Record 1-5” of the management table as needed using the times reported from the processors 17-1 and 17-2. Then, the processing time management unit 19 calculates the second predicted time by averaging the values of “Record 1-5”. Then, the processing time management unit 19 updates the value of “average of records 1-5” in the management table using the calculated second predicted time.

  The distribution unit 20 distributes a plurality of second data units (for example, a plurality of station data files) held in the database to corresponding stations (for example, the control station 30 and the base station 50).

[Operation example of management device]
An example of the processing operation of the management apparatus 10 having the above configuration will be described. FIG. 4 is a flowchart illustrating an example of a processing operation of the management apparatus according to the first embodiment.

  In the management device 10, the acquisition unit 11 acquires a plurality of first data units (step S101).

  The creating unit 12 executes “analysis processing” for each first data unit from the plurality of first data units (step S102). For example, the creation unit 12 analyzes update data (that is, entries) of the second update data group included in one first data unit one by one. In this analysis, a station corresponding to each update data is specified. Then, the creation unit 12 associates a plurality of update data with station identification information and configuration items corresponding to each update data.

  The creating unit 12 creates a plurality of second data units (step S103). For example, the creating unit 12 creates a plurality of second data units by arranging a plurality of update data associated with the same station identification information in an order according to the dependency relationship.

  Here, a plurality of first data units and a plurality of second data units will be described with reference to FIGS. FIG. 5 is a diagram illustrating an example of a plurality of first data units. FIG. 6 is a diagram illustrating an example of a plurality of second data units. In FIG. 5, the data unit DU1-1 is a first data unit corresponding to “station installation position in the wireless communication network”. The data unit DU1-2 is a first data unit corresponding to “sector / carrier information”. The data units DU1-3 are first data units corresponding to “frequency information”. In any of the data unit DU1-1, the data unit DU1-2, and the data unit DU1-3, update data (that is, each row in FIG. 5) for the stations A, B, and C is mixed.

  In FIG. 6, the data unit DU <b> 2-1 is a second data unit corresponding to “Station A”. The data unit DU2-2 is a second data unit corresponding to “Station B”. The data unit DU2-3 is a second data unit corresponding to “station C”. In any of the data unit DU2-1, the data unit DU2-2, and the data unit DU2-3, update data for one station (that is, each row in FIG. 6) is included.

  Returning to the description of FIG. 4, the processing time calculation unit 13 calculates the first predicted time for each second data unit (step S <b> 104). For example, the processing time calculation unit 13 determines the number of combinations of stations and configuration items based on the station identification information and configuration items received from the creation unit 12, that is, the number of entries for each configuration item in each second data unit. Count. Then, the processing time calculation unit 13 calculates a first prediction time for each second data unit based on each count value and the second prediction time for each configuration item stored in the storage unit 14. That is, the processing time calculation unit 13 multiplies the count value of each configuration item in a certain second data unit by the second prediction time corresponding to each configuration item, and adds all the multiplication results to obtain the first. A first predicted time for two data units is calculated.

  The scheduler 15 assigns each of the plurality of second data units created by the creation unit 12 to one of the processors 17-1 and 17-2 (step S105). For example, the scheduler 15 assigns each of the plurality of second data units to one of the processors 17-1 and 17-2 in order from the longest first prediction time calculated by the processing time calculation unit 13.

  Then, the scheduler 15 outputs an output command signal to the buffer 16 based on the allocation result.

  The processor 17 that has received the second data unit from the buffer 16 uses the second data unit to perform update processing on the database (step S106).

  FIG. 7 is a diagram for explaining the update processing according to the first embodiment. The left side in FIG. 7 shows how the data unit DU1-1, data unit DU1-2, and data unit DU1-3 are updated by one processor. Further, the right side in FIG. 7 shows a state in which the data unit DU2-1, the data unit DU2-2, and the data unit DU2-3 are updated by two processors. As can be seen from FIG. 7, a plurality of first data units grouped in units of configuration items are converted into a plurality of second data units grouped in units of stations, and they are used for a database by a plurality of processors. Thus, the update processing time can be shortened by ΔT.

  As described above, according to the present embodiment, in the management apparatus 10, the creation unit 12 corresponds to each of a plurality of stations from the plurality of first data units acquired by the acquisition unit 11, and each second data unit is A plurality of second data units including a second update data group related to a plurality of configuration items for one station are created. At this time, the creation unit 12 arranges the second update data group in each second data unit in the order based on the dependency of the plurality of configuration items. Then, the scheduler 15 assigns each of the plurality of second data units created by the creation unit 12 to either the processor 17-1 or the processor 17-2.

  With the configuration of the management apparatus 10, a plurality of second data units can be reflected in the database using a plurality of processors, so that the update processing time can be shortened. In addition, since the second update data group can be arranged in an order that matches the processing order in the update process of each processor, it is possible to prevent the occurrence of an error, and as a result, the update process time can be shortened.

  For example, the plurality of configuration items include the installation position of each station in the wireless communication network and the mounting information of each station. Then, the creation unit 12 arranges the update data related to the installation position before the update data related to the mounting information in each second data unit.

  In addition, the scheduler 15 assigns each of the plurality of second data units created by the creation unit 12 to either the processor 17-1 or the processor 17-2 in order from the longest first prediction time required for data update. Assign to.

  With this configuration of the management apparatus 10, it is possible to allocate to increase the operating rates of the processors 17-1 and 17-2. As a result, the update processing time can be shortened.

  In the management device 10, the processing time calculation unit 13 calculates the first predicted time for each second data unit based on the second predicted time required for data update for the update data corresponding to each configuration item. .

  With the configuration of the management device 10, the first predicted time can be calculated with high accuracy.
