COMMUNICATION SYSTEM, COMMUNICATION APPARATUS AND COMMUNICATION METHOD AS WELL AS PROGRAM

摘要

A communication system, a communication apparatus, a communication method, and a program for acquiring the advantage of a plurality of communication protocols is provided. A random number and a first communication information including first identification information of a communication apparatus is sent to another communication apparatus by using near field communication. Second communication information is received by the communication apparatus from the other communication apparatus by using near field communication. The second communication information includes second identification information of the other communication apparatus necessary to a second communication. The second communication is performed between the communication apparatus and the other communication apparatus by using the second communication information received by using the near field communication.

主权项

1. A communication apparatus comprising:
a first communication unit configured to send a random number and first communication information including first identification information of the communication apparatus to a second communication apparatus, and to receive second communication information including second identification information of the second communication apparatus necessary to a second communication from the second communication apparatus by using near field communication; and a second communication unit configured to perform the second communication between the communication apparatus and the second communication apparatus by using the second communication information received by the first communication unit, wherein the first communication unit is configured to (i) detect whether a RF field is present during a waiting phase that lasts for a first period of time and (ii) output an electromagnetic wave after the waiting phase ends, during a second period of time that occurs as a next period of time after the first period of time, based on no RF field being detected during the waiting phase.
