Communication system, connection destination control method, control apparatus and program
A communication system includes a terminal that communicates with a base station wirelessly; and a control device, in which the terminal includes a transmitter that transmits information on a location of the terminal, and the control device includes a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: acquiring the information on the location of the terminal, predicting a future location of the terminal based on the information on the location of the terminal and determining whether the terminal is to enter a dead zone by comparing the future position with the dead zone, and executing control for switching a connection destination of the terminal when the determining determines that the terminal is to enter the dead zone.
1 . A communication system comprising:
a terminal that communicates with a base station wirelessly; and
a control device, wherein
the terminal includes a transmitter configured to transmit information on a location of the terminal, and
the control device includes a processor; and
a memory that includes instructions, which when executed, cause the processor to:
acquire the information on the location of the terminal;
determine, using a plurality of sensors located in a service area, a dead zone according to a received signal quality from each sensor of the plurality of sensors;
predict a future location of the terminal based on the information on the location of the terminal and determine whether the terminal is to enter the dead zone by comparing the future location with the dead zone;
execute control for duplicating a connection destination of the terminal for when the processor determines that the terminal is to enter the dead zone; and
instruct the terminal to perform switching to a line with a high connection priority, when the processor determines that the terminal is not to enter the dead zone.
2 . The communication system according to claim 1 , wherein the information on the location of the terminal includes location information of the terminal, velocity information of the terminal, and atmospheric pressure sensor information at the location of the terminal.
3 . The communication system according to claim 1 , wherein the instructions, which when executed, cause the processor to compute 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 communicates with a base station wirelessly, and a control device, the method comprising:
transmitting, by the terminal, information on a location of the terminal;
acquiring, by the control device, information on a location of the terminal;
determining, using a plurality of sensors located in a service area, a dead zone according to a received signal quality from each sensor of the plurality of sensors;
predicting, by the control device, a future location of the terminal based on the information on the location of the terminal and determining, by the control device, whether the terminal is to enter the dead zone by comparing the future location with the dead zone;
executing, by the control device, control for duplicating a connection destination of the terminal when the control device determines that the terminal is to enter the dead zone; and
instructing, by the control device, the terminal to perform switching to a line with high connection priority, when the control device determines that the terminal is not to enter the dead zone.
5 . A control device in a communication system including a terminal that communicates with a base station wirelessly and the control device, the control device comprising:
a processor; and
a memory that includes instructions, which when executed, cause the processor to:
acquire information on a location of the terminal;
determine, using a plurality of sensors located in a service area, a dead zone according to a received signal quality from each sensor of the plurality of sensors;
predict a future location of the terminal based on the information on the location of the terminal and determine whether the terminal is to enter the dead zone by comparing the future location with the dead zone;
execute control for duplicating a connection destination of the terminal when the processor determines that the terminal is to enter the dead zone; and
instruct the terminal to perform switching to a line with high connection priority, when the processor determines that the terminal is not to enter the dead zone.
6 . The control device according to claim 5 , wherein the information on the location of the terminal includes location information of the terminal, velocity information of the terminal, and atmospheric pressure sensor information at the location of the terminal.
7 . A non-transitory computer readable storage medium storing a program, which when executed, causes a computer to function as the control device according to claim 5 .
