Abstract
A control device of the present invention is for provision in a gateway device that includes multiple communication units that perform wireless communication with terminal devices using different communication methods. Based on communication unit individual information that is acquired from the communication units and includes information indicating at least characteristics of the communication methods of the communication units, operations of the communication units are scheduled so as to prevent the overlapping of periods in which the communication units perform signal transmission/reception with the terminal devices.
Claims16
A control device for provision in a gateway device, comprising:
- a plurality of communication units, each including one or more processors, configured to perform wireless communication with a terminal device using different communication methods,
- wherein based on communication unit individual information that is acquired from the communication units and includes information indicating at least a characteristic of the communication method of each of the communication units, operations of the communication units are scheduled so as to prevent overlapping of periods in which the communication units perform signal transmission/reception with the terminal device;
- an occupied period detection unit, including one or more processors, configured to, in a case where one of the communication units performs signal transmission/reception with the terminal device, detect an occupied period that occurs due to the signal transmission/reception, based on the communication unit individual information that corresponds to the one communication unit;
- and
- a stop unit, including one or more processors, configured to:
- during the occupied period detected by the occupied period detection unit, stop signal transmission performed by a communication unit other than the communication unit that corresponds to the occupied period,
- determine whether or not a free state detection request regarding a wireless channel was made by a communication unit that is not performing signal transmission/reception with the terminal device in the occupied period, and
- in response to determining that the free state detection request was made, transmit a response indicating that the wireless channel is in a blocked state to the communication unit that made the free state detection request.
A control method for controlling a plurality of communication units included in a gateway device, the plurality of communication units being configured to perform wireless communication with a terminal device using different communication methods, the control method comprising:
- scheduling, based on communication unit individual information that is acquired from the communication units and includes information indicating at least a characteristic of the communication method of each of the communication units, operations of the communication units so as to prevent overlapping of periods in which the communication units perform signal transmission/reception with the terminal device;
- in a case where one of the communication units performs signal transmission/reception with the terminal device, detecting an occupied period that occurs due to the signal transmission/reception, based on the communication unit individual information that corresponds to the one communication unit;
- during the occupied period, stopping signal transmission performed by a communication unit other than the communication unit that corresponds to the occupied period;
- determining whether or not a free state detection request regarding a wireless channel was made by a communication unit that is not performing signal transmission/reception with the terminal device in the occupied period;
- and
- in response to determining that the free state detection request was made, transmitting a response indicating that the wireless channel is in a blocked state to the communication unit that made the free state detection request.
A non-transitory computer readable medium storing one or more instructions causing a computer to function as a control device for provision in a gateway device that includes a plurality of communication units that perform wireless communication with a terminal device using different communication methods, the one or more instructions causing the computer to execute:
- scheduling, based on communication unit individual information that is acquired from the communication units and includes information indicating at least a characteristic of the communication method of each of the communication units, operations of the communication units so as to prevent overlapping of periods in which the communication units perform signal transmission/reception with the terminal device;
- in a case where one of the communication units performs signal transmission/reception with the terminal device, detecting an occupied period that occurs due to the signal transmission/reception, based on the communication unit individual information that corresponds to the one communication unit;
- during the occupied period, stopping signal transmission performed by a communication unit other than the communication unit that corresponds to the occupied period;
- determining whether or not a free state detection request regarding a wireless channel was made by a communication unit that is not performing signal transmission/reception with the terminal device in the occupied period;
- and
- in response to determining that the free state detection request was made, transmitting a response indicating that the wireless channel is in a blocked state to the communication unit that made the free state detection request.
