Wireless communication terminal and connection setup method of wireless network

A wireless communication terminal that communicates in a wireless network comprising:

• a trigger receiving unit configured to receive a generation start trigger, an end trigger, a newly generating trigger, and a switching trigger;
• a connection setup unit configured to:
• transmit, during a period between the trigger receiving unit receiving the generation start trigger and the end trigger, a wireless network setup information sequentially to a plurality of first external terminals that transmit participation requests to the wireless communication terminal in order to establish a first ad-hoc wireless network between the plurality of first external terminals;
• and
• generate, after the first ad-hoc wireless network is established but before the end trigger is received by the trigger receiving unit, a new wireless network setup information when the newly generating trigger is received by the trigger receiving unit for establishing a second ad-hoc wireless network in response to a new participate request from a second external terminal and for performing a wireless connection setup with the second external terminal;
• a memory unit configured to store the wireless network setup information transmitted to the plurality of external terminals and the new wireless network setup information generated;
• and
• the connection setup unit further configured to, after the first ad-hoc wireless network is established but before the end trigger is received by the trigger receiving unit, read the wireless network setup information stored in the memory unit when a switching trigger is received by the trigger receiving unit for switching the first ad-hoc wireless network to a third ad-hoc wireless network for establishing the third ad-hoc wireless network in response to a new participate request from a third external terminal and for performing a wireless connection setup with the third external terminal.
