Method and system for obtaining emergency caller location
First Claim
1. A method for obtaining a subscriber location for a call from a phone, comprising:
- (a) determining by a phone system a subscriber access line identity of a subscriber access line, wherein the phone is coupled to a subscriber access line module via the subscriber access line, wherein the phone system receives and processes the call from the phone;
(b) sending a query from the phone system to a subscriber location query system, wherein the query comprises the subscriber access line identity;
(b1) receiving the query by the subscriber location query system, wherein the query comprises the subscriber access line identity, wherein the subscriber location query system comprises a datastore, wherein the datastore comprises a plurality of subscriber location records, wherein each subscriber location record comprises a subscriber access line identity attribute and a corresponding subscriber location attribute;
(b2) comparing the subscriber access line identity from the query to the subscriber access line identity attributes of the plurality of subscriber location records; and
(b3) if a match is found, returning to the phone system the subscriber location according to the matching subscriber location record; and
(c) receiving from the subscriber location query system the subscriber location corresponding to the subscriber access line identity, wherein the subscriber location comprises a physical or link layer property of the subscriber access line module to which the subscriber access line is coupled.

Abstract
Methods and systems for obtaining the location of a caller during an emergency or other telephone call. Before or during a call, a phone system can obtain from one or more sources a subscriber access line identity associated with a subscriber location record that includes a subscriber access line identity attribute and a subscriber location attribute. A phone system can send a query that includes the subscriber access line identity to a subscriber location query system that returns a subscriber location record or a subscriber location to the phone system. The phone system can then display the caller location information to a phone system, an agent or operator so that emergency services can be quickly and accurately dispatched. Using similar procedure and a memory, phone systems can also determine if a subscriber phone has or is changing location. Methods for testing the emergency call capabilities of a subscriber access line.

10. A method for providing a subscriber location for a call from a phone, comprising:
-
(a) receiving a query from a phone system to a subscriber location query system, wherein the query comprises a subscriber access line identity of a subscriber access line, wherein the phone is coupled to a subscriber access line module via the subscriber access line, wherein the phone system receives and processes the call from the phone, wherein the subscriber location query system comprises a datastore, wherein the datastore comprises a plurality of subscriber location records, wherein each subscriber location record comprises a subscriber access line identity attribute and a corresponding subscriber location attribute; (b) comparing the subscriber access line identity from the query to the subscriber access line identity attributes of the plurality of subscriber location records; and (c) if a match is found, returning to the phone system the subscriber location according to the matching subscriber location record, wherein the subscriber location comprises a physical or link layer property of the subscriber access line module to which the subscriber access line is coupled. - View Dependent Claims (11, 12, 13)

14. A system, comprising:
-
a subscriber access line having a subscriber access line identity; a subscriber access line module; a phone coupled to the subscriber access line module via the subscriber access line; a subscriber location query system, comprising a subscriber location corresponding to the subscriber access line identity; and a phone system coupled to the subscriber access line module via a line separate from the subscriber access line, wherein the phone system receives and processes a call from the phone, wherein the phone system determines the subscriber access line identity, wherein the phone system sends a query to the subscriber location query system, wherein the query comprises the subscriber access line identity, wherein the subscriber location query system comprises a datastore, wherein the datastore comprises a plurality of subscriber location records, wherein each subscriber location record comprises a subscriber access line identity attribute and a corresponding subscriber location attribute, wherein the subscriber location query system receives the query from the phone system, compares the subscriber access line identity from the query to the subscriber access line identity attributes of the plurality of subscriber location records, and if a match is found, returning to the phone system the subscriber location according to the matching subscriber location record; and wherein the phone system receives from the subscriber location query system the subscriber location, wherein the subscriber location comprises a physical or link layer property of the subscriber access line module to which the subscriber access line is coupled. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
