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 and/or latitude 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 and/or latitude change of location of the portable computing device. The origin of an emergency voice call can be determined based on a location area identifier that corresponds to a geographical area encompassing a geographical location being represented by the location data. In addition, the origin of an emergency voice call can be determined based on the cellular base station, or other station of communication of a portable computing device, and transmitted to a public safety answering point.
