<p>PROBLEM TO BE SOLVED: To provide an adhoc network constitution, a terminal and a communication system, which are simultaneously connected to both LAN so as to perform communication, in environment where a local area network (trunk network connection-type LAN) and temporary LAN (adhoc LAN) which is not connected to the trunk network exist. SOLUTION: An adhoc network 300 is defined as one multi-cast group used by the trunk network 100 and trunk network connection-type LAN 110. Thus, the terminal 301 which is simultaneously connected to adhoc LAN 100 and trunk network connection-type LAN 110 and performs communication can join adhoc LAN 300 in a form similar to that for entering the multi-cast group of conventional trunk network connection-type LAN. Thus, terminal constitution becomes easy and the terminal can simultaneously be connected to adhoc LAN and trunk network connection-type LAN.</p> |
