Universal emergency number ELIN based on network address ranges
First Claim
1. A method for providing emergency location information to an emergency service provider, comprising:
- providing at least one set of Network Layer addresses, the at least one set of Network Layer addresses comprising at least one Network Layer address, and at least one Emergency Location Information Number (ELIN) corresponding to the at least one set of Network Layer addresses; and
upon the occurrence of a predetermined event, mapping, by a processor, a selected Network Layer address against the at least one set of Network Layer addresses to determine an ELIN for the selected Network Layer address.

Abstract
A method for providing emergency location information to an emergency service provider is provided. The method, in one implementation, includes the steps of (a) providing a plurality of sets (e.g., ranges) of OSI Layer 3 or Network Layer addresses; (b) receiving an emergency call from a calling device having an OSI Layer 3 or Network Layer address; (c) mapping the calling address against the plurality of sets of addresses to determine an ELIN for the calling address; and (d) forwarding the ELIN to a public safety answer point. Each set of addresses comprises a plurality of addresses, and a plurality of ELINs corresponds to the plurality of sets of addresses. In each set of addresses, a corresponding one of the plurality of ELINs is typically common to a plurality of addresses.

18. A communication system for providing emergency location information to an emergency service provider, comprising:
-
a processor readable memory comprising at least one set of Network Layer addresses, the at least one set of Network Layer addresses comprising at least one Network Layer address, and at least one set of Emergency Location Information Numbers (ELINs) comprising at least one Emergency Location Information Number (ELIN), the at least one set of ELINs corresponding to the at least one set of Network Layer addresses; and an emergency locating agent operable, upon the occurrence of a predetermined event and when executed by a processor, to map a selected Network Layer address against the at least one set of Network Layer addresses to determine an ELIN in the corresponding at least one set of ELINs for the selected Network Layer address. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A communication system comprising:
-
a processor; and a memory, the memory being encoded with an emergency location table readable by the processor, the emergency location table comprising; a plurality of sets of Open Systems Interconnect Layer 3 addresses, each set of Layer 3 addresses comprising a plurality of Layer 3 addresses; and a plurality of Emergency Location Information Numbers (ELINs), each Emergency Location Information Number (ELIN) corresponding to a respective set of Layer 3 addresses stored in the memory. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41)

42. A method for handling dropped emergency calls, comprising:
-
(a) receiving, from a first communication device and by a port, a first communication to one of an emergency service provider and a public safety answering point; (b) determining, by an emergency locating agent executed by a processor, an Emergency Location Information Number (ELIN) by mapping a source address of the first communication device against address ranges in an emergency location table, wherein the source address and addresses in the range of addresses are Open Systems Interconnect Layer 3 addresses; (c) forwarding, by the processor, the ELIN to the one of an emergency service provider and public safety answering point; (d) receiving, by a trunk, a second communication from the one of the emergency service provider and public safety answering point; and (e) directing, by the processor, the second communication to an address associated with the first communication device and to the ELIN identified in step (b).
