A METHOD, OF ENABLING AN EMERGENCY CALL IN A IEEE 802.11E ENABLED WIRELESS LOCAL AREA NETWORK

摘要

A method of enabling an emergency call in an IEEE 802.11e enabled wireless local area network The present invention is based on inserting an additional information into the admission control requests (7,8) defined in IEEE 802.11e in order to identify and differentiate the requests (7,8) related to emergency calls. By doing this, the entity entitled to perform the admission control, i.e. the central controller (3), or, in other words, the entity entitled to decide whether there are enough network resources for a requested call to be established, can handle a resource request for an emergency call in a well adapted way.
