Method and System for Providing Location Updates
First Claim
1. A method of updating location information of a portable computing device, comprising:
- receiving location data from a positioning device;
communicating with a call center through a voice link;
mapping a dual-tone multi-frequency signal to a pre-determined range of movement;
transmitting to the call center the dual-tone multi-frequency signal when a longitude measurement in the location data indicates a change in longitude that is within the pre-determined rage of movement, wherein the dual-tone multi-frequency signal is transmitted as an indicator of longitude change of location of the portable computing device; and
transmitting to the call center the dual-tone multi-frequency signal when a latitude measurement in the location data indicates a change in latitude that is within the pre-determined rage of movement, wherein the dual-tone multi-frequency signal is transmitted as an indicator of latitude change of location of the portable computing device.

Abstract
A method and system of updating location information of a portable computing device is disclosed. Location data is received from a positioning device. A voice link is utilized for communication between the portable computing device and a call center. A dual-tone multi-frequency signal is mapped to a pre-determined range of movement. The dual-tone multi-frequency signal is transmitted to the call center when a longitude measurement in the location data indicates a change in longitude that is within the pre-determined rage of movement. The dual-tone multi-frequency signal is transmitted as an indicator of longitude change of location of the portable computing device. In addition, the dual-tone multi-frequency signal is transmitted to the call center when a latitude measurement in the location data indicates a change in latitude that is within the pre-determined rage of movement. The dual-tone multi-frequency signal is transmitted as an indicator of latitude change of location of the portable computing device.

10. A portable computing device, comprising:
-
a positioning device that receives location data;
a memory module that stores a table that includes a dual-tone multi-frequency signal mapped to a pre-determined range of movement;
a voice communication transceiver that communicates with a call center through a voice link; and
a processor configured to determine when a longitude measurement in the location data indicates a change in longitude that is within the pre-determined rage of movement, wherein the processor is further configured to transmit the dual-tone multi-frequency signal to the call canter through the voice communication transceiver, the dual-tone multi-frequency signal being transmitted as an indicator of longitude change of location of the portable computing device, the processor being configured to determine when a latitude measurement in the location data indicates a change in latitude that is within the pre-determined rage of movement, wherein the processor is further configured to transmit the dual-tone multi-frequency signal to the call canter through the voice communication transceiver, the dual-tone multi-frequency signal being transmitted as an indicator of latitude change of location of the portable computing device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of updating location information of a portable computing device, comprising:
-
receiving location data from a positioning device;
communicating with a call center through a data link;
mapping a movement indicator to a pre-determined range of movement;
transmitting to the call center the movement indicator in a first data packet when a longitude measurement in the location data indicates a change in longitude that is within the pre-determined rage of movement, wherein the movement indicator indicates a longitude change of location of the portable computing device; and
transmitting to the call center the movement indicator in a second data packet when a latitude measurement in the location data indicates a change in latitude that is within the pre-determined rage of movement, wherein the movement indicator indicates a latitude change of location of the portable computing device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
