The invention discloses a multi-mode terminal access system and method under a 5G fusion network architecture based on digital twinning, the system is a three-layer double-closed-loop digital twinning network architecture, the architecture comprises three layers of structures from top to bottom, and the three layers of structures sequentially comprise a network application layer, a digital twinning layer, a digital twinning layer, a digital twinning layer, a digital twinning layer, a digital twinning layer and a digital twinning layer from top to bottom, waiting for next mapping; a digital twin network layer in which a digital network simulates the operation of an actual physical network in real time and in advance and issues control to the actual physical network according to a simulation result; and the bottom layer is a physical network layer which is connected with the twinning network layer through an actual interface, continuously provides the actual communication environment condition for the digital twinning network through data acquisition, and simultaneously receives and executes the optimal decision result simulated by the digital twinning network. The method has good real-time performance and expansibility, and is beneficial for processing network conditions in a variable environment.

Description

technical field [0001] The invention belongs to the field of communication technology, in particular to the field of network fusion technology, in particular to a multi-mode terminal access system and method based on a digital twin-based 5G fusion network architecture. Background technique [0002] With the development of the Internet of Things, the existing network cannot meet the needs of large-scale ubiquitous connections, and the multiple requirements of Internet of Things applications for network delay and bandwidth. Therefore, 5G technology is widely used in various vertical industries to improve the performance of existing networks. In order to reduce network deployment costs, most vertical industries integrate 5G and traditional 4G / WLAN networks to provide network services that meet their needs for devices in the system. The selection of user access points in a heterogeneous network environment will not only affect the data rate of user equipment (UE, User Equipment)...

AI Technical Summary

Problems solved by technology

[0003] Although the existing converged network access selection technology can effectively improve network performance, it has the following problems: 1) poor real-time performance; 2) trial and error costs are too high in emergencies

These network selection methods have certain advantages in a network with a relatively stable network environment and relatively few sudden failures, but their dynamics and robustness are not good.

Specifically, the existing solutions lead to the inflexibility of multi-mode terminal access in the converged network, which cannot adapt to the dynamically changing heterogeneous network; at the same time, the existing solutions have low fault tolerance, and the choice of wrong access solutions directly affects the real network. performance
