Preferential treatment for emergency callback
Abstract:
Disclosed herein are techniques for allowing callbacks from emergency call centers to a subscriber, including when restrictions in place would have otherwise prevented the call. The technique may employ Camel, thereby triggering Camel when a subscriber dials an emergency or public safety call center. Camel's Mobile Switching Center (MSC) will set up a call to the emergency call center, and the Service Control Point (SCP) will suspend or disable the restrictions in place, such as parental control features. The restrictions may be suspended indefinitely, for a specific time period, until another triggering event, or the like. The subscriber, in this manner, can receive a callback from the emergency call center.
