Abstract
A mechanism is provided to suspend or modify incoming call restrictions for a subscriber station for some time period when it is detected that an emergency call was made by that subscriber station, so as to disable the restriction that would otherwise block completion of an incoming call to that station. This allows a call placed by emergency personnel in response to the emergency call from the subscriber station (i.e. when the emergency personnel calls back the user that is involved in the emergency) to bypass any restrictions setup by the subscriber or by the network that would otherwise block the callback and allows the emergency callback to potentially reach the caller. This approach results in a systematic solution to blocking of emergency callbacks that applies to various kinds of restriction services yet is relatively simple to administer.
