The proliferation of advanced data communications introduces new opportunities and challenges for National Security / Emergency Preparedness (NS/EP) communications. Expanded data capabilities enhance the ability for Service Users to carry out their NS/EP mission. At the same time, high data traffic volumes place significant demands upon Service Provider's networks and can hamper their ability to support the offered traffic load when these networks are impaired due to congestion and/or damage from natural or human-caused disasters. The NS/EP Data Transport Service is designed to address these needs.

This Technical Report (TR) analyzes NS/EP Data Transport Service invocation / revocation for an Evolved Packet System (EPS), including the associated user interactions with the NS/EP Service Provider, for several key use case scenarios as specified in 3GPP TS 22.153, Multimedia priority service (Release 17). It describes support of the NS/EP Data Transport Service based on updated Policy and Charging Control (PCC) features for the EPS Bearer Service as specified in 3GPP Release 17.
