Patent ID: 7391749

Claim:
A wireless communication terminal having an ability to perform asynchronous communications and perform synchronous communications using different communication bands depending on a communication quality, the wireless communication terminal being capable of concurrently establishing a plurality of communication links with a plurality of other wireless communication terminals, the wireless communication terminal comprising: an asynchronous communication link management section operable to manage an asynchronous communication band used by an asynchronous communication link which is already established with any other wireless communication terminal; a synchronous communication link management section operable to manage a synchronous communication band used by a synchronous communication link which is already established with any other wireless communication terminal; a link establishment determination section operable to determine, in response to a request to establish a new synchronous communication link, whether the new synchronous communication link can be established at a requested communication quality without disrupting the already-established asynchronous communication link, based on the asynchronous communication band and the synchronous communication band; and a link establishment section operable to establish the new synchronous communication link if the link establishment determination section determines that the new synchronous communication link can be established at the requested communication quality without disrupting the already-established asynchronous communication link.
