Abstract
There is provided a communication control apparatus including an acquisition unit configured to acquire determination information indicating a result obtained by determining, on the basis of a use status of a frequency band owned by a first operator that provides a radio communication service, whether it is possible for another operator to use the frequency band, and a determination unit configured to determine whether a second operator is allowed to use the frequency band on the basis of the acquired determination information.
Claims16
A communication control apparatus comprising:
- an acquisition unit configured to acquire determination information indicating a result obtained by determining, on the basis of a use status of a frequency band owned by a first operator that provides a radio communication service, whether it is possible for another operator to use the frequency band;
- and a determination unit configured to determine whether a second operator is allowed to use the frequency band on the basis of the acquired determination information;
- wherein the acquisition unit acquires determination information on each cell indicating a result obtained by determining, on the basis of the use status of the frequency band of each cell, whether it is possible for another operator to use the frequency band of each cell, and wherein the determination unit determines whether the second operator is allowed to use the frequency band of each cell on the basis of the determination information on each cell wherein, when it is determined that the second operator is allowed to use the frequency band of a first cell of the first operator, the frequency band is used by a base station for a second cell of the second operator for communication with a terminal apparatus of the second operator, the second cell overlapping with the first cell at least in part, and wherein a base station for the first cell of the first operator and the base station for the second cell of the second operator transmit and receive information for reducing interference in the frequency band via an interface between the base station of the first operator and the base station of the second operator.
A base station comprising:
- a radio communication unit configured to wirelessly communicate with a terminal apparatus in a first cell of a first operator by using a frequency band owned by the first operator, the first operator providing a radio communication service;
- and a control unit configured to, when it is determined whether the second operator is allowed to use the frequency band of each cell on the basis of determination information on each cell indicating a result obtained by determining whether it is possible for another operator to use the frequency band of each cell on the basis of a use status of the frequency band of each cell, and when it is determined that the second operator is allowed to use the frequency band of the first cell, stop use of the frequency band by a terminal apparatus of the first operator in the first cell in accordance with control of a communication control apparatus;
- wherein, when it is determined that the second operator is allowed to use the frequency band of the first cell of the first operator, the frequency band is used by a base station for a second cell of the second operator for communication with a terminal apparatus of the second operator, the second cell overlapping with the first cell at least in part, and wherein a base station for the first cell of the first operator and the base station for the second cell of the second operator transmit and receive information for reducing interference in the frequency band via an interface between the base station of the first operator and the base station of the second operator.
A terminal apparatus comprising:
- a radio communication unit configured to wirelessly communicate with a base station for a first cell of a first operator in the first cell by using a frequency band owned by the first operator, the first operator providing a radio communication service;
- and a control unit configured to, when it is determined whether the second operator is allowed to use the frequency band of each cell on the basis of determination information on each cell indicating a result obtained by determining whether it is possible for another operator to use the frequency band of each cell on the basis of a use status of the frequency band of each cell, and when it is determined that the second operator is allowed to use the frequency band of the first cell, stop use of the frequency band in the first cell in accordance with control of the base station;
- wherein, when it is determined that the second operator is allowed to use the frequency band of the first cell of the first operator, the frequency band is used by a base station for a second cell of the second operator for communication with a terminal apparatus of the second operator, the second cell overlapping with the first cell at least in part, and wherein a base station for the first cell of the first operator and the base station for the second cell of the second operator transmit and receive information for reducing interference in the frequency band via an interface between the base station of the first operator and the base station of the second operator.
A communication control method comprising:
- acquiring determination information indicating a result obtained by determining, on the basis of a use status of a frequency band owned by a first operator, whether it is possible for another operator to use the frequency band, the first operator providing a radio communication service;
- and determining whether a second operator is allowed to use the frequency band on the basis of the acquired determination information;
- wherein, when it is determined that the second operator is allowed to use the frequency band of a first cell of the first operator, the frequency band is used by a base station for a second cell of the second operator for communication with a terminal apparatus of the second operator, the second cell overlapping with the first cell at least in part, and wherein the base station for the first cell of the first operator and the base station for the second cell of the second operator transmit and receive information for reducing interference in the frequency band via an interface between the base station of the first operator and the base station of the second operator.
