<p>According to the invention, a wireless terminal and an access point AP of a wireless local area network WLAN being part of the LAN are able to exchange data for the setup of a wireless link while the wireless terminal being unknown to the AP. The wireless terminal and the AP comprise an interface for the wireless link and means for interacting via the interface by exchanging data frames. The interacting means are adapted for constructing generated data frames for transmission and for decoding received data frames. Such wireless link corresponds to a restricted association being identified by a specific data from an exchanged data frame. And the restricted association corresponds to a restricted access within the LAN, the restricted access being defined by a dedicated virtual LAN VLAN. Such restricted access may be advantageously adapted for a telecommunication like an emergency call set up from the wireless terminal.</p> |
