Abstract

The present application relates to the field of communication technology, and in particular to a B5G-oriented core network system based on a non-stack protocol, which is used to solve the problems of large signaling overhead and delay in the prior art. This application mainly includes: a global network database, a control plane, a management plane, and a user plane. Among them, by introducing the non-stack protocol framework into the 5G-oriented core network system, reorganizing the network elements in the network system, decoupling the control of the network The control plane and the user plane integrate the control function logic in the core network system into the control plane. At the same time, the control plane and the data plane are separated. The control function logic is centralized and the data plane is flattened to simplify signaling interaction and reduce The purpose of delaying the process and reducing network signaling overhead.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a B5G-oriented core network system based on a non-stack protocol. Background technique [0002] The network architecture of the traditional Long Term Evolution (LTE) core network system is as follows: figure 1 shown. The network elements included in it mainly include: Mobility Management Entity (MME) 11, Home Subscriber Server (HSS) 12, Serving Gateway (SGW) 13, Data Gateway (PGW) 14 and Policy and Charging Rules Function Unit (PCRF) 15 Wait. Each network element is divided by function and runs on a separately designed hardware platform, and data communication between network elements is carried out through a specially designed interface / protocol. For example, on SGW13 and PGW14, user plane and control plane functions are tightly coupled. It can be seen that, regarding a specific evolved packet system mobility management (EPS mobility management, EMM) pro...
