Abstract

Disclosed is that when the first wireless communication apparatus is connected to a terminal apparatus such as a wireless access point wirelessly, the second wireless communication apparatus performs the communication with the first wireless communication apparatus by a short distance wireless communication, then the first wireless communication apparatus transmits participation information to participate in the network to the second wireless communication apparatus by the short distance wireless communication, and the second wireless communication apparatus is connected to the network based on the received participation information so as to communicate with the first wireless communication apparatus through the terminal apparatus.

Claims

1. A wireless communication system comprising a terminal apparatus, a first wireless communication apparatus and a second wireless communication apparatus which exist in a network,

wherein the first wireless communication apparatus comprises:

a first wireless section to perform a wireless communication with the terminal apparatus or the second wireless communication apparatus;

a second wireless section to perform a short distance wireless communication with the second wireless communication apparatus; and

a first control section to instruct the second wireless section to transmit participation information to the second wireless communication apparatus so as to participate in the network, in a case where a communication with the second wireless communication apparatus is handed over from the short distance wireless communication performed by the second wireless section to the wireless communication performed by the first wireless section, and in the case where the first wireless section is connected to the terminal apparatus so that the first wireless communication apparatus participates in the network,

and wherein the second wireless communication apparatus comprises;

a third wireless section to perform the wireless communication with the terminal apparatus or the first wireless communication apparatus;

a fourth wireless section to perform the short distance wireless communication with the first wireless communication apparatus; and

a second control section to instruct the third wireless section to be connected to the network so that the second wireless communication apparatus participates in the network based on the participation information, in a case where the communication with the first wireless communication apparatus is handed over from the short distance wireless communication performed by the fourth wireless section to the wireless communication performed by the third wireless section, and in the case where the participation information is obtained by the fourth wireless section.

2. The wireless communication system as claimed in claim 1, wherein the terminal apparatus is a wireless access point,

and wherein in a case where the network is in an infrastructure mode, the participation information is information for being connected to the wireless access point.

3. The wireless communication system as claimed in claim 1, wherein in a case where the network is in an ad-hoc mode, the participation information is information to perform the wireless communication with the first wireless communication apparatus in the network.

4. A wireless communication method of a wireless communication system comprising a terminal apparatus, a first wireless communication apparatus and a second wireless communication apparatus which exist in a network,

wherein a communication of the first wireless communication apparatus and the second wireless communication apparatus is handed over from a short distance wireless communication to another wireless communication,

and wherein the wireless communication method comprises:

transmitting participation information to the second wireless communication apparatus through the short distance wireless communication so as to participate in the network, in a case where the first wireless communication apparatus is connected to the terminal apparatus through the wireless communication so that the first wireless communication apparatus participates in the network; and

participating of the second wireless communication apparatus in the network by being connected to the network through the wireless communication based on the participation information, in the case where the second wireless communication apparatus receives the participation information through the short distance wireless communication.
