METHOD AND SYSTEM FOR LAST GASP DEVICE IDENTIFICATION
First Claim
1. A method for device identification comprising:
- determining a mass event has occurred in a wireless network from a reception of a plurality of signals each having a last gasp message (LGM);
sampling a plurality of mapped zones associated with a base station, each mapped zone including a plurality of wireless device endpoints associated with the mapped zone, the sampling including determining whether any of a subset of the endpoints associated with the given mapped zone are disconnected from the wireless network;
identifying which mapped zones are associated with a disconnected endpoint in a zone list;
determining a length of time of the mass event; and
selectively providing the zone list to identify disconnected endpoints based at least upon the length of time of the mass event.

Abstract
A method for device identification includes determining a mass event has occurred in a wireless network from a reception of a plurality of signals each having a last gasp message, sampling a plurality of mapped zones associated with a base station, identifying which mapped zones are associated with a disconnected endpoint in a zone list, determining a length of time of the mass event, and selectively providing the zone list to identify disconnected endpoints based at least upon the length of time of the mass event. Each mapped zone includes a plurality of wireless device endpoints associated with the mapped zone. The sampling includes determining whether any of a subset of the endpoints associated with the given mapped zone are disconnected from the wireless network.
