Abstract

Abstract: Driven by technologies such as SDN, NFV and cloud computing, the 5G network architecture is based on service and has features of control and forwarding separation. The diversification of 5Gservices, terminals and business models in the future has new requirements for session management. This paper firstly introduces the 5G system architecture and protocol stack, then focuses on the terminal NAS PDU session management mechanism, and illustrates the design method of the terminal protocol conformance test case to provide reference for the development of5Gterminal test standards.

Key words: 5G, sessionmanagement, protocol conformance testing
