Spectrum control system, spectrum control method, wireless communication system, and computer readable medium

A spectrum control method comprising steps of:

• identifying a base station or a cell that does not satisfy a predetermined level of communication quality based on information regarding a network status;
• extracting a plurality of base stations or a plurality of cells including a base station or a cell other than the identified base station or the identified cell as additional band allocating candidates;
• and
• allocating an additional band to the base station or the cell that satisfies a predetermined condition among the plurality of extracted base stations or the plurality of extracted cells,
• wherein the extracting comprises extracting the identified base station or the identified cell, which is the base station or the cell that does not satisfy the predetermined level of communication quality, and a peripheral base station or a peripheral cell around the identified base station or the identified cell as the additional band allocating candidates;
• when the identified base station or the identified cell does not satisfy the predetermined condition, the allocating the additional band to the peripheral base station or the peripheral cell that satisfies the predetermined condition;
• and
• the predetermined condition comprises a number or a ratio of subordinate terminals including a communication function in the additional band exceeding a predetermined value.

A non-transitory computer readable medium storing a spectrum control program that causes a computer to execute:

• an identifying process that identifies a base station or a cell that does not satisfy a predetermined level of communication quality based on information regarding a network status;
• an extracting process that extracts a plurality of base stations or a plurality of cells including a base station or a cell other than the identified base station or the identified cell as additional band allocating candidates;
• and
• an allocating process that allocates an additional band to the base station or the cell that satisfies a predetermined condition among the plurality of extracted base stations or the plurality of extracted cells,
• wherein the extracting process extracts the identified base station or the identified cell, which is the base station or the cell that does not satisfy the predetermined level of communication quality, and a peripheral base station or a peripheral cell around the identified base station or the identified cell as the additional band allocating candidates;
• when the identified base station or the identified cell does not satisfy the predetermined condition, the allocating process allocates the additional band to the peripheral base station or the peripheral cell that satisfies the predetermined condition;
• and the predetermined condition comprises a number or a ratio of subordinate terminals including a communication function in the additional band exceeding a predetermined value.

A spectrum control system comprising:

• identifying means for identifying a base station or a cell that does not satisfy a predetermined level of communication quality based on information regarding a network status;
• extracting means for extracting a plurality of base stations or a plurality of cells including a base station or a cell other than the identified base station or the identified cell as additional band allocating candidates;
• and
• allocating means for allocating an additional band to the base station or the cell that satisfies a predetermined condition among the plurality of extracted base stations or the plurality of extracted cells,
• wherein the extracting means extracts the identified base station or the identified cell, which is the base station or the cell that does not satisfy the predetermined level of communication quality, and a peripheral base station or a peripheral cell around the identified base station or the identified cell as the additional band allocating candidates;
• when the identified base station or the identified cell does not satisfy the predetermined condition, the allocating means allocates the additional band to the peripheral base station or the peripheral cell that satisfies the predetermined condition;
• and the predetermined condition comprises a number or a ratio of subordinate terminals including a communication function in the additional band exceeding a predetermined value.
