GPS-based uRLLC network slice generation device and generation method

Abstract

The invention relates to a GPS-based uRLLC network slice generation device and generation method. The method comprises: connecting a terminal with GPS information of a server of an access network according to the uRLLC; and judging a server of an access network to be switched by the connection terminal or servers of a plurality of possibly switched access networks, copying local NFV resources to the next one or more access network servers in advance through an NFV orchestrator of the core network before switching, and synchronizing necessary information. According to the invention, data layerarchitecture optimization is carried out on a sub-scene of access network switching, so that the network reliability is improved and the user network delay is reduced. The end-to-end network transmission delay is reduced, and the user experience of uRLLC services is improved. Under the conditions that network basic setting is not modified, a new network protocol is not designed and a large amountof capital investment is not needed, more reliable and low-delay response is carried out on the uRLLC scene, and the user experience of the uRLLC scene is improved to the maximum extent from the aspect of software optimization.

Description

technical field [0001] The present invention relates to the technical field of handover or reselection devices in a wireless communication network, in particular to a device and method for generating uRLLC network slices based on GPS. Background technique [0002] With the development of 5G technology, 5G Internet of Vehicles has become the investment focus of communication companies. At the 18th Shanghai International Automobile Industry Exhibition, which closed in April 2019, China Mobile displayed a series of products such as smart city, smart transportation, and 5G unmanned vehicles. , Volvo and other car companies have reached a strategic cooperation on 5G Internet of Vehicles. Qualcomm also regards Internet of Vehicles as a strategic focus, and 14 big-name cars have adopted the Qualcomm Snapdragon 820A in-vehicle information platform. [0003] From the perspective of urban management, intelligent driving will improve traffic efficiency, relieve congestion, greatly red...

Problems solved by technology

However, there are still two major barriers to achieving this goal with 5G technology. One is that the 5G network needs to reach a fairly high level of coverage, and the other is that the low-latency and high-reliability connections of roadside facilities for intelligent network connections need to be guaranteed , especially the second point, excessive delay or low reliability may directly lead to traffic accidents and casualties

[0006] In the existing technology, the invention patent with the application number 201810844473.8 "a uRLLC slicing and request method for 5G users" also aims to solve the high reliability and l
