A method of associating call back data with an emergency call to a call center

摘要

A method of communication to at least one wireless unit originating an emergency call. The method includes the step of receiving at least one tag identifier in response to the emergency call originating from the at least one wireless unit. Once the tag identifier is received, a wireless call back number corresponding with the at least one tag identifier may be transmitted. A public service answering point emergency call register ("PSAP-ECR") may receive the at least one tag identifier and transmits the wireless call back number over a D interface.
