Abstract

A wireless communication terminal comprises a trigger receiving unit, a participation request receiving unit, and a connection setup unit. The trigger receiving unit receives a predetermined trigger. The participation request receiving unit receives requests to participate in a wireless network from an external terminal which does not participate in the wireless network in which the wireless communication terminal has participated, using wireless communication. The connection setup unit makes each of participation requests received by the participation request receiving unit from a plurality of external terminals correspond to one trigger received by the trigger receiving unit. The connection setup unit performs a connection setup which makes each of the plurality of external terminals participate in the wireless network in response to each of the participation requests, in the order in which the participation requests are received.

Claims

1. A wireless communication terminal comprising:

a trigger receiving unit which receives a predetermined trigger;

a participation request receiving unit which receives requests to participate in a wireless network from an external terminal which does not participate in the wireless network in which the wireless communication terminal has participated, using wireless communication; and

a connection setup unit which makes each of participation requests received by the participation request receiving unit from a plurality of external terminals correspond to one trigger received by the trigger receiving unit, and performs a connection setup which makes each of the plurality of external terminals participate in the wireless network in response to each of the participation requests, in the order in which the participation requests are received.

2. The wireless communication terminal according to claim 1,

wherein the connection setup unit performs the connection setup on one of the plurality of external terminals and

receives the participation request from another terminal among the plurality of external terminals.

3. The wireless communication terminal according to claim 1, wherein the trigger received by the trigger receiving unit is a trigger which is generated when the wireless communication terminal is started.

4. The wireless communication terminal according to claim 1, further comprising an instruction input unit which receives a predetermined instruction from a user,

wherein the trigger received by the trigger receiving unit is a trigger which is generated based on the predetermined instruction received by the instruction input unit.

5. The wireless communication terminal according to claim 1, further comprising:

a memory unit which stores contents of the connection setup; and

a determining unit which determines whether the wireless communication terminal is separated from the wireless network in which the wireless communication terminal has participated,

wherein the wireless communication terminal is separated from the wireless network based on a determination result of the determining unit.

6. The wireless communication terminal according to claim 5, wherein the connection setup unit performs the connection setup based on the contents of the connection setup stored in the memory unit, after the wireless communication terminal is separated from the wireless network.

7. A connection setup method of wireless network, comprising:

receiving a predetermined trigger;

receiving requests to participate in a wireless network from a plurality of external terminals which does not participate in the wireless network in which a wireless communication terminal has participated, using wireless communication;

storing in a memory unit participation request information related to participation requests received from the plurality of external terminals within a predetermined period including the time when the trigger is received; and

performing a connection setup which makes each of the plurality of external terminals, whose participation requests are received within the predetermined period, participate in the wireless network, in the order in which the participation requests are received, based on the participation request information stored in the memory unit.
