Radio resource setting method, base station, radio resource setting system, and non-transitory computer readable medium

A base station that performs wireless communication with a terminal in a second communication area that is at least one of a neighboring communication area of a first communication area or a communication area including part of the first communication area, the base station comprising:

• a load measuring unit that measures a load of the second communication area;
• and
• an allocation ratio resource setting unit that calculates a first delay index of the first communication area using the load of the first communication area notified from an other base station that manages the first communication area,
• calculating using the load of the second communication area a second delay index of the second communication area in case where the radio resources whose use is limited in the second communication area have been set, and
• calculating a ratio of radio resources whose use is limited in the second communication area based on the first delay index and the second delay index.

A base station that, when there is a second communication area that is at least one of a neighboring communication area of a first communication area or a communication area including part of the first communication area, performs wireless communication with a terminal in the first communication area, the base station comprising:

• a load measuring unit that measures a load of the first communication area;
• and
• a priority resource requesting unit that calculates a first delay index of the first communication area using the load of the first communication area,
• calculating using the load of the second communication area transmitted from an other base station that manages the second communication area a second delay index of the second communication area in case where the radio resources whose use is limited in the second communication area have been set, and
• calculating a ratio of radio resources whose use is limited in the second communication area based on the first delay index and the second delay index, and notifying the other base station that manages the second communication area of a result of the calculation.

A radio resource setting system that, when there are a first communication area managed by a first base station and a second communication area including at least part of the first communication area and managed by a second base station, sets radio resources that the first and second base stations can use for wireless communication with a terminal, wherein the radio resource setting system is configured to:

• obtain loads of the first communication area and the second communication area;
• calculate a first delay index of the first communication area using the load of the first communication area;
• calculate using the load of the second communication area a second delay index of the second communication area in case where the radio resources whose use is limited in the second communication area have been set;
• calculate a ratio of the radio resources whose use is limited in the second communication area based on the first delay index and the second delay index;
• and
• set the radio resources whose use is limited in the second communication area using the ratio of the radio resources whose use is limited.

A non-transitory computer readable medium having stored thereon a program that is executed by a computer of a base station that performs wireless communication with a terminal in a second communication area that is at least one of a neighboring communication area of a first communication area or a communication area including part of the first communication area, the program causing the computer to execute:

• obtaining a load of the second communication area;
• calculating a first delay index of the first communication area using a load of the first communication area notified from an other base station that manages the first communication area;
• calculating using the load of the second communication area a second delay index of the second communication area in case where the radio resources whose use is limited in the second communication area have been set;
• and
• calculating a ratio of the radio resources whose use is limited in the second communication area based on the first delay index and the second delay index.
