Communication system, connection destination control method, control apparatus and program
A communication system includes a terminal configured to wirelessly communicate with a base station and a control device. The terminal includes a transmission unit that transmits location information of the terminal. The control device includes a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: setting an area around a dead zone as a preliminary dead area, acquiring location information of the terminal, and determining whether the terminal is in the preliminary dead area by comparing the location information of the terminal with the preliminary dead area and performing control for switching a connection destination of the terminal when the determining determines that the terminal is in the preliminary dead area.
1 . A communication system comprising:
a terminal configured to wirelessly communicate with a base station; and
a control device,
wherein the terminal includes a transmitter that transmits location information of the terminal, and
wherein the control device includes:
a processor; and
a memory that includes instructions, which when executed, cause the processor to execute the following steps:
setting an area around a dead zone as a preliminary dead area, wherein the preliminary dead area has a predetermined radius larger than a radius of the dead zone,
acquiring location information of the terminal, and
determining whether the terminal is in the preliminary dead area by comparing the location information of the terminal with the preliminary dead area and performing control for switching a connection destination of the terminal when the determining determines that the terminal is in the preliminary dead area.
2 . The communication system according to claim 1 , wherein, when the terminal is in a plurality of preliminary dead areas, the processor selects, from among base stations corresponding to the plurality of preliminary dead areas, a base station such that a distance from the dead zone is largest, as a connection destination of the terminal.
3 . The communication system according to claim 1 , wherein the processor calculates the dead zone based on reception quality received from a plurality of sensors.
4 . A connection destination control method in a communication system including a terminal that wirelessly communicates with a base station and a control device, the method comprising:
transmitting, by the terminal, location information of the terminal;
setting, by the control device, an area around a dead zone as a preliminary dead area, wherein the preliminary dead area has a predetermined radius larger than a radius of the dead zone;
acquiring, by the control device, location information of the terminal;
determining, by the control device, whether the terminal is in the preliminary dead area by comparing the location information of the terminal with the preliminary dead area; and
performing, by the control device, control for switching a connection destination of the terminal in response to determining that the terminal is in the preliminary dead area.
5 . A control device in a communication system including a terminal that wirelessly communicates with a base station and a control device, the control device comprising:
a processor; and
a memory that includes instructions, which when executed, cause the processor to execute the following steps:
setting an area around a dead zone as a preliminary dead area, wherein the preliminary dead area has a predetermined radius larger than a radius of the dead zone;
acquiring location information of the terminal, and
determining whether the terminal is in the preliminary dead area by comparing the location information of the terminal with the preliminary dead area and performing control for switching a connection destination of the terminal when the determining determines that the terminal is in the preliminary dead area.
6 . The control device according to claim 5 , wherein, when the terminal is in a plurality of preliminary dead areas, the processor selects, from among base stations corresponding to the plurality of preliminary dead areas, a base station such that a distance from the dead zone is largest, as a connection destination of the terminal.
7 . The control device according to claim 5 , wherein the processor calculates the dead zone based on reception quality received from a plurality of sensors.
8 . A non-transitory computer readable storage medium storing a program, which when executed, causing a computer to function as the control device according to claim 5 .
