System and method for a cellular communication networks originated 911 call emergency response system

摘要

A cellular communication network has a mobile switching center (MSC) that maintains a GPS location data of a mobile handset referenced by a mobile identification number (MIN) and an electronic serial number (ESN) in addition to a geographic cell number in an HLR database for handsets operating in the network. The GPS location data of the handset may be used for efficient paging to a specific cell to route incoming calls to the handset, route emergency responder calls with the physical location of the handset and to program the handset with the handset transmission strength to the nearest cell tower In lieu of using triangulation algorithm.

主权项

1. A cellular communication network based emergency response system, comprising:
a. a mobile switching center (MSC) of a cellular communication network that maintains, in an home location record (HLR) database, in addition to identification of cell towers, a GPS location data of a mobile cell phone device, for devices that are operating in the network; b. the MSC has an interface to an emergency response (ER) system; c. the MSC for a received 911 emergency call from a wireless device retrieves the device's GPS location data from the HLR database and sends to the ER system over the interface.
