FIG. 7 is a third diagram illustrating the processing of the frequency arrangement device according to the present embodiment.
Next, the processing of the frequency allocation device will be described with reference to FIGS.
The allocation information acquisition unit 12 of the frequency allocation device 10 obtains first allocation information A and second allocation information B (Step S1). The frequency allocation device 10 may acquire the first allocation information A and the second allocation information B recorded in a storage unit such as the HDD 106 in advance. Alternatively, the frequency allocation device 10 may acquire the first allocation information A and the second allocation information B from the management device 50. The arrangement information acquisition unit 12 outputs the acquired first arrangement information A and second arrangement information B to the arrangement information determination unit 13.

  The arrangement information determining unit 13 determines the arrangement information to be frequency-reduced among the plurality of acquired arrangement information. The arrangement information of the frequency reduction target is the arrangement information for reducing the frequency due to the interference when the frequencies included in the frequency group of the other arrangement information are used at the same time as the frequencies included in the frequency group of the other arrangement information. Point to. In the present embodiment, the frequency-reduction target location information is referred to as first location information A. The arrangement information other than the arrangement information of the frequency reduction target is referred to as other arrangement information (second arrangement information B).

  The arrangement information determining unit 13 identifies one frequency included in the frequency group of the second arrangement information B, which is another arrangement information, and determines the identified frequency and the frequency of the arrangement information (first arrangement information A) to be reduced. Each frequency included in the group is compared (step S2). In step S2 of FIG. 5, A1 shows an example in which the frequency 2a included in the second arrangement information B is shown in a diagram showing the positional relationship of the frequencies in the frequency bandwidth indicated by the frequency group included in the first arrangement information A. ing. In step S2 in FIG. 5, A2 indicates an example in which the frequency 2b included in the second arrangement information B is illustrated in a diagram illustrating the positional relationship of the frequencies in the frequency bandwidth indicated by the frequency group included in the first arrangement information A. ing. Although not shown, the arrangement information determining unit 13 similarly includes the frequency 2c included in the frequency group of the second arrangement information B in the frequency group of the arrangement information (first arrangement information A) to be reduced in frequency. Compared with each frequency. That is, the arrangement information determining unit 13 performs the process of step S2 for all frequencies included in the frequency group of the second arrangement information B, which is another arrangement information.

  When the specified frequency overlaps with the frequency included in the frequency group of the first arrangement information A, the arrangement information determination unit 13 deletes the frequency included in the frequency group of the first arrangement information A that overlaps the specified frequency. . When the frequency specified in the second allocation information B and each frequency included in the frequency group of the first allocation information A are simultaneously used, the allocation information determination unit 13 determines whether the wireless signal included in the frequency group of the first allocation information A Calculates the interference value affecting the radio signal of the frequency specified in the second arrangement information B, and specifies the frequency in the frequency group of the first arrangement information A that gives the interference indicating the interference value. A known technique (such as the technique disclosed in the above-mentioned non-patent document) is used for calculating the interference value and specifying the frequency of the interference. The arrangement information determining unit 13 deletes the frequency at which the interference value has an influence equal to or more than the predetermined value. As a result, the arrangement information determining unit 13 generates temporary arrangement information when one frequency specified from other arrangement information is included in the arrangement information to be subjected to frequency reduction (step S3).

  The arrangement information determining unit 13 generates the temporary arrangement information A1 'and the temporary arrangement information A2' as shown in the diagram of step S3 of FIG. 5 by the processing of step S3. In the provisional arrangement information A1 ', since the frequency 2a overlaps the frequency 1a in A1 in step S2, the frequency 1d is a frequency which has an influence of a predetermined value or more on the frequency 2a specified in the second arrangement information B. Therefore, this is an example in which the frequency 1a and the frequency 1d of the first arrangement information A are deleted. As a result of calculating the interference value affecting the signal of the frequency specified in the second arrangement information B in A2 of the step S2, the temporary arrangement information A2 ′ determines that the interference value affecting the frequency 2b specified in the second arrangement information B is predetermined. This is an example in the case where the frequency 1a is deleted because the influence is greater than or equal to the threshold value. Although not shown, the arrangement information determination unit 13 also performs the process of step S3 using the frequency 2c of the second arrangement information B and each frequency of the first frequency information A.

The arrangement information determining unit 13 selects temporary arrangement information having the most remaining number of frequencies of the frequency group of the first arrangement information A from the temporary arrangement information generated in step S3 (step S4). The selected temporary arrangement information is referred to as first temporary integrated arrangement information C. The arrangement information determination unit 13 includes, among the frequencies of the frequency group of the second arrangement information B, the second group including the remaining frequencies 2a and 2c other than the frequency 2b of the second arrangement information B included in the first temporary integrated arrangement information C. The arrangement information B1 is extracted.

  The arrangement information determination unit 13 determines whether the first temporary integrated arrangement information C generated in step S4 includes a frequency specified in a frequency group included in the second arrangement information in a predetermined number. If it is determined that the frequency included in the frequency group of the second arrangement information is included in the first temporary integrated arrangement information C generated in step S4, the first The temporary integrated arrangement information C is output as integrated arrangement information and recorded in a storage unit such as the HDD 106. If the arrangement information determination unit 13 determines that the frequency included in the frequency group of the second arrangement information does not include the frequency designated in advance in the first temporary integrated arrangement information C generated in step S4, The process proceeds. In the present embodiment, an example in which the integrated arrangement information specifies that the frequencies included in the frequency group of the second arrangement information include two frequencies will be described below.

  That is, the arrangement information determination unit 13 specifies one frequency from the second arrangement information B1 including the remaining frequencies. The arrangement information determining unit 13 compares the specified frequency with the frequencies included in the frequency group of the first temporary integrated arrangement information C (Step S5). In step S5 of FIG. 6, C1 is a diagram showing the positional relationship of the frequencies in the frequency bandwidth indicated by the frequency group included in the first temporary integrated arrangement information C. An example is shown in which the frequency 2a of the second arrangement information B1 indicating the remaining frequencies not included in the temporary integrated arrangement information is shown. In step S5 in FIG. 6, C2 is a diagram showing the positional relationship of the frequencies in the frequency bandwidth indicated by the frequency group included in the first temporary integrated arrangement information C. An example is shown in which the frequency 2c of the second arrangement information B1 indicating the remaining frequencies not included in the temporary integrated arrangement information is shown. As described above, the arrangement information determining unit 13 determines all the frequencies included in the second arrangement information B1 including the remaining frequencies not included in the temporary integrated arrangement information among the frequencies of the second arrangement information B, which is another arrangement information. , The process of step S5 is performed.

  When the frequency specified from the second allocation information B1 including the remaining frequency overlaps with the frequency included in the frequency group of the first temporary integrated allocation information C, the allocation information determining unit 13 overlaps the specified frequency. The frequency included in the frequency group of the first temporary integrated arrangement information C is deleted. Further, when the frequency specified from the second allocation information B1 including the remaining frequency and the frequency included in the frequency group of the first temporary integrated allocation information C are simultaneously used, the allocation information determining unit 13 sets the first allocation information An interference value is calculated in which the radio signal based on the frequency included in the frequency group A affects the radio signal of the frequency specified in the second arrangement information B1. In addition, the arrangement information determination unit 13 specifies a frequency in the frequency group of the first arrangement information A that gives the interference indicating the interference value. As described above, the calculation of the interference value and the specification of the frequency giving the interference use a known technique. The arrangement information deciding unit 13 deletes the frequency of the first arrangement information A exerting the influence of the interference of the predetermined value or more. Thereby, the arrangement information determining unit 13 generates temporary arrangement information in a case where one frequency specified from the second arrangement information B1 including the remaining frequencies is included in the first temporary integrated arrangement information C (step S6).

  The arrangement information determination unit 13 generates the temporary arrangement information C1 'and the temporary arrangement information C2' as shown in the diagram of step S6 in FIG. 7 by the processing of step S6. As a result of calculating the interference value affecting the signal of the frequency specified in the second allocation information B1 in the temporary allocation information C1 ′ in C1 of step S5, the interference of the predetermined frequency or more to the frequency specified in the second allocation information B1 is calculated. This is an example in which the frequency 1c is deleted because of the influence. In the provisional arrangement information C2 ′, since the frequency 2c and the frequency 1e overlap in C2 in step S5, the frequency 1e of the first arrangement information A is deleted, and interference affecting the signal of the frequency specified in the second arrangement information B1 is performed. As a result of calculating the value, the frequency specified in the second arrangement information B1 is affected by interference equal to or greater than a predetermined threshold, and thus the frequency 1c is deleted.

  The allocation information determining unit 13 selects the temporary allocation information C1 'having the most remaining number of frequencies of the frequency group of the first allocation information A from the temporary allocation information generated in step S6 (step S7). The selected temporary arrangement information is referred to as second temporary integrated arrangement information D.

  The arrangement information determining unit 13 determines whether or not the second temporary integrated arrangement information D generated in step S7 includes a frequency specified in a frequency group included in the second arrangement information in a predetermined number. If it is determined that the frequency included in the frequency group of the second arrangement information is included in the second temporary integrated arrangement information D generated in step S7, the second The temporary integrated arrangement information D is output as integrated arrangement information and recorded in a storage unit such as the HDD 106. As shown in FIG. 7, the second temporary integrated arrangement information D includes a specified number of two frequencies included in the frequency group of the second arrangement information. Therefore, the arrangement information determining unit 13 outputs and records the second temporary integrated arrangement information D as integrated arrangement information.

  In the present embodiment, an example in which the number N of frequencies included in the original second arrangement information is three, and the number M of frequencies of the second arrangement information to be included in the integrated arrangement information is designated as 2. Is explained. However, any number of frequencies may be included in the second arrangement information, and the number M of frequencies of the second arrangement information to be included in the integrated arrangement information may be any number as long as M ≦ N.

  For example, when there are three pieces of arrangement information, one piece of frequency reduction target arrangement information is determined from the three pieces of arrangement information, and frequencies are sequentially specified one by one from the other pieces of arrangement information. And subsequent processing may be performed in a similar manner. In this case, also in step S5, the frequencies of one by one may be sequentially specified one by one from the other arrangement information, and the processes of steps S6 and S7 may be performed.

  Next, the frequency allocating unit 14 allocates a frequency to the wireless station device including the DAMA access slave device 31 using the integrated arrangement information. In this case, the DAMA access slave device 31 makes a frequency allocation request to the DAMA access master device 21. The DAMA access main device 21 acquires the unified allocation information from the frequency allocation device 10, and specifies the frequency recorded in the unified allocation information. The integrated arrangement information stores information on a plurality of frequencies used by the wireless station device for wireless communication in a certain frequency band. This frequency may be information having a predetermined frequency width. The integrated arrangement information holds the correspondence between each frequency and the communication speed. The frequency allocation request from the DAMA access slave device 31 may include communication speed information. In this case, the frequency allocating unit 14 allocates a frequency corresponding to the requested communication speed. Frequency allocating section 14 transmits information on the frequency to be allocated to DAMA access slave device 31.

Although the embodiment of the present invention has been described above, according to the above-described processing, the frequency allocation device 10 has a plurality of frequencies determined as frequencies used for wireless communication of the wireless station device in the first frequency bandwidth. Acquisition of arrangement information including information of one frequency group. Further, the frequency allocation device 10 obtains allocation information including information of a second frequency group having a plurality of frequencies determined as frequencies used for wireless communication of the wireless station device in the second frequency bandwidth. Then, the frequency allocation device 10 determines the frequency included in the first frequency group based on the interference value affecting each frequency when the frequency included in the first frequency group and the frequency included in the second frequency group are used simultaneously. From the frequency used for wireless communication. Further, the frequency allocation device 10 sequentially increases the number of frequencies included in the second frequency group, and when the interference value affecting each frequency is less than a predetermined interference value, the frequency included in the first frequency group and the second The integrated arrangement information including the frequencies included in the two frequency groups is determined.
According to such processing, the frequency allocation apparatus 10 can perform more appropriate frequency allocation to the wireless station apparatus using different frequency allocation information. For example, the frequency allocation device 10 can allocate a frequency at which interference is unlikely to occur to the wireless station device. In addition, the frequency allocation device 10 integrates frequency allocation information according to the communication speed, and uses a frequency that is more appropriate and less likely to cause interference with wireless station devices located in the same area that communicate at different communication speeds. Thus, a frequency corresponding to the communication speed can be applied.
