Patent ID: 7190947

Claim:
A wireless communication device comprising: a receiver configured to receive information about allowed access classes; a processor coupled to the receiver, the processor configured to determine whether an emergency access class is allowed; and a transmitter coupled to the processor, the transmitter configured to transmit an emergency call after the emergency access class is determined to be allowed, wherein the processor is configured to accept an incoming emergency call for a predefined time period after the transmission of the emergency call, further comprising: a timing circuit coupled to the processor, the timing circuit configured to generate a start time of the predefined time period and to provide timing information to the processor; and a memory circuit configured to store the start time, wherein the processor determines whether the predefined time period has elapsed based upon comparison between the start time in the memory circuit and the timing information received from the timing circuit, wherein the timing circuit is configured to generate the start time upon receipt of a channel assignment.
