Abstract

An emergency call recognition system which is activated when an off-hook situation occurs, which recognizes when an emergency number is dialed with or without the presence of a dial tone, and which provides the caller a communication channel to complete such a call. The present invention is used to give priority to emergency telephone calls. Typically the present invention is used in wireless local loop systems, however the present invention can also be incorporated into a conventional telephone system. The present invention uses an emergency call recognition system to determine if a person is dialing an emergency telephone number. If the emergency call recognition system recognizes a dialed telephone number as an emergency telephone number, then the caller is provided with a communication channel to complete the telephone call. The caller is provided a communication channel even if all of the communication channels are in use. This is accomplished by disconnecting calls that are not of an emergency nature.
