FAULT ROUTING OF AN EMERGENCY COMMUNICATION
First Claim
1. A method, comprising:
- determining, at a first network node, unavailability of a second network node for an emergency service routing number (ESRN) related to an emergency communication;
querying, at the first network node, a database for administrative data associated with the ESRN, in response to the second network node being unavailable for the ESRN;
updating, at the first network node, an identifier associated with the administrative data with data indicative of a user device originating the emergency communication; and
delivering, by the first network node, the updated identifier in a session initiation message to the second network node.

Abstract
Aspects of the disclosure relate to routing of an emergency communication under fault conditions. Routing can be implemented in a packet-switching (PS) network that provides voice service. For a network node of the PS network, availability to route the emergency communication through a specific emergency service routing number (ESRN) can be determined and, in response to the network node being unavailable, administrative data associated with the ESRN can be accessed. In addition, an identifier associated with the administrative data can be updated (e.g., created or modified) with data indicative of the device that originated the emergency communication. The administrative data and the resulting identifier can be delivered to a second network node that can route the emergency communication to an emergency service network.

12. An apparatus, comprising:
-
a memory comprising computer-executable instructions; and a processor functionally coupled to the memory and configured, by the computer-executable instructions, to determine unavailability of a first network node for an emergency service routing number (ESRN) related to an emergency communication; query a database for administrative data associated with the ESRN; update an identifier associated with the administrative data with data indicative of a user device originating the emergency communication, wherein the update yields an updated identifier; and deliver the updated identifier in a session initiation message to a second network node. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
