Introduction

Executive Order 13618¹ outlines the Assignment of National Security and Emergency Preparedness Communications Functions and defines the following policy:

"The Federal Government must have the ability to communicate at all times and under all circumstances to carry out its most critical and time sensitive missions. Survivable, resilient, enduring, and effective communications, both domestic and international, are essential to enable the executive branch to communicate within itself and with: the legislative and judicial branches; State, local, territorial, and tribal governments; private sector entities; and the public, allies, and other nations. Such communications must be possible under all circumstances to ensure national security, effectively manage emergencies, and improve national resilience."

This Technical Report (TR) proposes the allocation of LTE Access Class 14 for National Security and Emergency Preparedness (NS/EP) communications in order to address the need for priority treatment of NS/EP communications.

Purpose

The purpose of this TR is to provide operational guidance regarding the assignment and use of the 3GPP LTE specifications for Access Class Barring to support National Security and Emergency Preparedness (NS/EP) Next Generation Network Priority-Services (NGN-PS). 3GPP TS 22.011 Section 4 contains the following general description of Access Classes:

"All UEs are members of one out of ten randomly allocated mobile populations, defined as Access Classes 0 to 9. The population number is stored in the SIM/USIM. In addition, UEs may be members of one or more out of 5 special categories (Access Classes 11 to 15), also held in the SIM/USIM.
