Abstract
Various systems and methods for servicing emergency calls are disclosed. One such method includes providing a location database that includes physical location information about a communication device. This location information can be accessed either directly or indirectly by an emergency service answering system, while concealing the information from a network responsible for terminating the call.
Claims14
A method for updating a physical location record in a database in connection with servicing a telecommunications call, the method comprising:
- receiving a telecommunications call originating from a communication device;
- determining whether the communication device is associated with an automatic locating device;
- if the communication device is associated with an automatic locating device, then querying for a current set of physical location coordinates generated by the automatic locating device;
- receiving the current set of physical location coordinates;
- comparing the current set of physical location coordinates to a set of physical location coordinates contained in the physical location record;
- and
- if the current set of physical location coordinates are different from contained set of physical location coordinates, updating the physical location record to include the current set of physical location coordinates.
A method for servicing transitory telecommunication calls, the method comprising:
- providing a database having at least one physical location record;
- receiving a telecommunications call originating from a communication device, wherein the communication device is associated with an automatic locating device;
- receiving a current set of physical location coordinates generated by the automatic locating device;
- comparing the current set of physical location coordinates to a prior set of physical location coordinates contained in the physical location record;
- if current set of physical location coordinates are different from the prior set of physical location coordinates, updating physical location record to include the current set of physical location coordinates;
- and
- transmitting the current set of physical location coordinates to a third party for use in providing dispatch services.
A method for updating a physical location record in a database in connection with servicing a telecommunications call, the method comprising:
- receiving a telecommunications call originating from a communication device;
- if the communication device is associated with an automatic locating device:
- receiving a current set of physical location coordinates generated by the automatic locating device;
- comparing the current set of physical location coordinates to a set of physical location coordinates contained in the physical location record;
- and
- if current set of physical location coordinates are different from contained set of physical location coordinates, updating physical location record to include the current set of physical location coordinates;
- if the communication device is not associated with an automatic locating device:
- receiving an Internet Protocol (IP) address associated with a device involved in servicing the telecommunications call;
- comparing the received IP address to a prior IP address associated with prior telecommunications call involving the communication device;
- if the received IP address does not match the prior IP address, then querying the communication device for a current physical location information;
- receiving the current physical location information;
- and
- registering the current physical location information in association with the communication device in the physical location record.
