COMPUTER-RELATED DEVICE FOR LOCATING THE ORIGINATOR OF AN EMERGENCY CALL VIA A CELLULAR OR DATA NETWORK BY TRIANGULATION AND RECEIVED SIGNAL STRENGTH IDENTIFIERS

摘要

The claimed invention consists of a device for use with a computer. The device may include a transceiver and control logic. The control logic (a) receives one or more first signals carrying corresponding one or more cellular tower identifiers or wireless access point identifiers, (b) determines one or more signal strengths (RSSI) of the one or more first signals and a location of the communication device based on the one or more cellular towers or wireless access point identifiers and the one or more signal strengths of said first signals via triangulation, (c) receives a second signal corresponding to an emergency call, and (d) transfers, via a cellular network or a packet switched network, a third signal carrying an indicator of the location of said communication device to a remote device to aid emergency personnel in identifying the location of said communication device, said control logic implementing said emergency call as one of a cellular-based call via said cellular network and a VoIP call via said packet switched network.
