Abstract
Device independent access to stored caller data during an emergency communications event. A call server intercepts an emergency call and determines the capabilities of a calling device. Based on calling device capability, the call server uses one or more of the following device independent methods to ascertain a caller identity, independent of a calling device: interactive voice response redirect, HTTP authentication, SIP INFO method, biometric recognition, human interaction, and alternate number dialing. A caller identity is then used to query a subscriber database for a unique caller profile database key (CPDBK) assigned to the caller (unless a CPDBK is already determined). A call server uses a CPDBK to query a caller profile database (CPDB) for relevant caller data. Relevant caller data and the intercepted emergency communications event are then passed to an emergency call processing system, whereby relevant caller data may be used to more effectively address an emergency situation.
