Communication method and communication apparatus

By using IPSec or QUIC protocol messages between the terminal and the non-3GPP access gateway, and converting them into NAS messages for communication, the problem of high network deployment complexity in non-3GPP access scenarios is solved, achieving more efficient terminal access and resource utilization, and supporting more terminal devices to access 5GC.

AI Technical Summary

Technical Problem

In non-3GPP access scenarios, when a terminal communicates with the core network through a non-3GPP access gateway, it is necessary to deploy various types of access gateways to meet different NAS protocol requirements, resulting in high network deployment complexity and not supporting terminal devices without SIM cards and NAS modules to access 5GC.

Method used

The terminal communicates with the non-3GPP access gateway via IPSec messages or QUIC protocol messages. The non-3GPP access gateway converts these messages into NAS messages and generates corresponding NAS messages to communicate with control plane network elements, simplifying the terminal structure and supporting terminal devices without NAS modules to access 5GC.

Benefits of technology

It reduces network deployment complexity, reduces signaling overhead, improves session establishment and deregistration efficiency, and supports more types of terminal devices to access 5GC.

Abstract

A communication method and a communication apparatus, which are used for implementing communication between a terminal and a core network by means of a unified non-3GPP access gateway, thereby reducing the complexity of network deployment. The method comprises: receiving a first message from a terminal, the first message being used for requesting authentication, connection establishment or connection release, and the first message being an internet protocol security (IPSec) message, or the first message being a quick user datagram protocol internet connection (QUIC) protocol message; and sending a second message to a control plane network element, the second message being a non-access stratum (NAS) message determined on the basis of the first message.
