Abstract

A method is provided for processing emergency service calls from a user device to a PSAP, the user device having an associated line number and being configured to originate calls from fixed and mobile access networks. The method includes determining whether a call from the user device originates from a home location in a fixed access network. When the call is determined to have originated from the home location in the fixed access network, the call is routed to the PSAP, where a location of the user device is determined based on the Automatic Number Identification (ANI) included in signaling associated with the call. When the call is determined not to have originated from the home location in the fixed access network, adding pseudo-ANI to signaling associated with the call and routing the call to the PSAP, where the location of the user device is determined based on the pANI.

Claims (4)

1 . A method of processing emergency service calls from a user device to a public safety answering point (PSAP), the user device having an associated line number and being configured to originate calls from a fixed access network and a mobile access network, the method comprising:

determining whether a call from the user device originates from a home location in the fixed access network;

when the call is determined to have originated from the home location in the fixed access network, routing the call to the PSAP, wherein a location of the user device is determined based on the Automatic Number Identification (ANI) included in signaling associated with the call; and

when the call is determined not to have originated from the home location in the fixed access network, adding pseudo-ANI to signaling associated with the call and routing the call to the PSAP, wherein the location of the user device is determined based on the pANI.
