E9-1-1 Call Congestion Management
Full Name:
NENA Standards for E9-1-1 Call Congestion Management
Document Type: Standard
Number: 03-006 v1

This document provides a framework for consideration of the various factors impacting the management of call congestion and traffic engineering for E9-1-1 networks. A network reference model is provided for use in referring to generic E9-1-1 network entities. This is followed by a section that outlines generally accepted industry practices for traffic engineering for E9-1-1 networks.

This document focuses on the use of trunking capacity between network entities as the primary means of managing call congestion. It is acknowledged that enhanced methods of managing call congestion may be developed that leverage new intelligent network capabilities. It is also acknowledged that other points within the various networks involved in delivery of E9-1-1 calls have an impact on the level of service and call volumes supported, however, these potential enhancements and other network elements are not within the scope of this version of this document. This Standard is intended to provide a guideline for all telecommunications carriers (including local exchange carriers (LECs), competitive local exchange carriers (CLECs), commercial mobile radio services (CMRS), satellite carriers, etc), E9-1-1 network providers, and public safety agencies for how to manage call congestion in an overall E9-1-1 network.

This document is intended to provide greater parity between any type of E9-1-1 call, regardless of the source of it’s origination (wireless, traditional landline, VoIP, PBX/MLTS etc.).

Use of this Standard will:

  • Provide greater parity between any type of E9-1-1 call, regardless of the source of it’s origination (wireless, traditional landline, VoIP, PBX/MLTS etc.)
  • Establish that it is not only acceptable but necessary to control call congestion to provide a reliable robust E9-1-1 System.
