METHOD FOR SHARING INFORMATION ON NETWORK FUNCTION IN INITIAL CONNECTION PROCESS OF 5G CORE NETWORK

摘要

Disclosed is a method for sharing information between network functions in an initial connection process of a 5G core network. The present invention can reduce the procedure of transmitting a large amount of data by transmitting session-related information between access and mobility management function (AMF) and session management function (SMF), which are network functions, in a process of establishing a protocol data unit (PDU) session in the early stage of the 5G core network using shared memory. In addition, the present invention can facilitate shared memory management by processing a plurality of PDU sessions by generating a unique shared key for the terminal and the PDU session.;COPYRIGHT KIPO 2020
