Location evaluation for callers that place emergency telephone calls over packet networks
First Claim
1. A service node for an emergency telephone call placed from a caller over a packet network, the service node comprising:
- a packet network interface configured to receive the emergency telephone call from the packet network; and
a processing system configured to process a source packet address for the emergency telephone call based on first packet address characteristics for a first location to determine if the caller is at the first location, direct a transfer of the emergency telephone call with a first indication that the caller is at the first location if the caller is at the first location, and direct a transfer of the emergency telephone call with a second indication that the caller is not at the first location if the caller is not at the first location.

Abstract
A service node receives an emergency telephone call from a packet network. The service node processes a source packet address for the emergency telephone call based on first packet address characteristics to determine if the caller is at the first location. The service node transfers the emergency telephone call with a first indication that the caller is at the first location if the caller is at the first location and transfers the emergency telephone call with a second indication that the caller is not at the first location if the caller is not at the first location. A location server receives a query for the emergency telephone call indicating the source packet address, processes the source packet address based on packet address characteristics to determine the current location of the caller, and transfers a response indicating the current location.
