Communication device, communication scheme determination method, and program
First Claim
1. A communication device comprising:
- circuitry configured tosend a first polling signal in a specific polling cycle and receive a first response signal sent from a counterpart device in response to the first polling signal, based on a first scheme;
send a second polling signal in a longer polling cycle than the first polling signal and receive a second response signal sent from the counterpart device in response to the second polling signal, based on a second scheme; and
wait for reception of one of the first and second response signal from a time point of the other one of the first and second response signal being received for a predetermined period of time longer than the polling cycle of the second polling signal, and determine a scheme usable by the counterpart device based on the reception result.

Abstract
Provided is a communication device including a first communication unit that is capable of sending a polling-signal in a specific polling cycle and receiving a response-signal sent from a counterpart device in response to the polling-signal, based on a first scheme, a second communication unit that is capable of sending a polling-signal in a longer polling cycle than the first communication unit and receiving a response-signal sent from the counterpart device in response to the polling-signal, based on a second scheme, and a scheme determination unit that waits for reception of the response-signal by the second or the first communication unit for a specific period of time longer than the polling cycle of the second communication unit with a time of the response-signal being received by the first or the second communication unit as a reference, and determines a scheme usable by the counterpart device based on the reception result.

10. A communication scheme determination method comprising:
-
sending a first polling signal of a first scheme in a specific polling cycle and sending a second polling signal of a second scheme in a longer polling cycle than the first scheme; receiving a response signal of the first or the second scheme sent from a counterpart device in response to the first and second polling signals sent in the sending; and waiting for reception of one of the response signal of the second or the first scheme from a time point of the other one of the response signal of the second or the first scheme being received for a predetermined period of time longer than the polling cycle of the second scheme, and determining a scheme usable by the counterpart device based on the reception result. - View Dependent Claims (11)

12. A non-transitory recording medium encoded with a program for causing a computer to realize a method comprising:
-
sending a first polling signal of a first scheme in a specific polling cycle and sending a second polling signal of a second scheme in a longer polling cycle than the first scheme; receiving a response signal of the first or the second scheme sent from a counterpart device in response to the first and second polling signals sent in the sending; and waiting for reception of one of the response signal of the second or the first scheme from a time point of the other one of the response signal of the second or the first scheme being received for a predetermined period of time longer than the polling cycle of the second scheme, and determining a scheme usable by the counterpart device based on the reception result. - View Dependent Claims (13)
