    • 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.
    • 一种紧急呼叫识别系统,其在摘机状态发生时被激活,该识别系统识别当或不存在拨号音时拨打紧急号码的时间,并且为呼叫者提供通信信道来完成这种呼叫。 本发明用于优先应急电话。 通常,本发明用于无线本地环路系统中,然而本发明也可以并入传统的电话系统中。 本发明使用紧急呼叫识别系统来确定一个人是否拨打紧急电话号码。 如果紧急呼叫识别系统将拨打的电话号码识别为紧急电话号码,则向主叫方提供通信信道以完成电话呼叫。 即使所有通信信道都在使用中,呼叫者也被提供通信信道。 这是通过断开不是紧急情况的呼叫来实现的。
