Abstract
Controlling establishment of a synchronous communication link depending on how the communication band is used, the controlling being applied to a wireless communication terminal which supports both asynchronous communications and synchronous communications. A asynchronous communication link management section manages the presence of asynchronous communication links between wireless communication terminals. A synchronous communication link management section manages the presence/status of synchronous communication links between wireless communication terminals. When a request to establish a new synchronous communication link is made by a user, a link establishment determination section determines whether the currently-established asynchronous communication links can be maintained based on the presence/status of the asynchronous and synchronous communication links and the requested communication quality. The link establishment determination section allows the requested synchronous communication link to be established only when it is determined that the currently-established asynchronous communication links can be maintained.
