scope:

This Standard describes end-to-end call/session flows for various wireline and wireless access technologies, in addition to the IMS Core Network call/session flows in support of NGN GETS (Emergency Telecommunications Service (ETS)). These call/session flows illustrate how an NGN GETS call/session can be processed, and address call/session set-up, termination, and on-going activities of the call/session for the various NGN GETS service types and access technologies. The call/session flows are based on various wireline and wireless Standards/Specifications. This Standard describes call/session flows for the following:

• Wireline access technologies:

o Digital Subscriber Line (DSL)

o Fiber

o Cable

o Ethernet.

• Wireless access technologies:

o Evolved Universal Terrestrial Radio Access Network (E-UTRAN)

o Universal Terrestrial Radio Access Network (UTRAN)

o High Rate Packet Data (HRPD)

o evolved High Rate Packet Data (eHRPD)

o Worldwide Interoperability for Microwave Access (WiMAX).

The material in this Standard is meant to provide a high-level illustrative description and is not intended to be exhaustive. If inconsistencies are found between this material and NGN GETS (ETS) requirements contained within other Standards/Specifications, the requirements in those Standards/Specifications take precedence.
