5G network slicing system for serving city center environment

Abstract

The invention discloses a 5G network slicing system for serving a city center environment, which is characterized by comprising a 5G communication module, a data storage module, a weight calculation module, a network slicing module and a resource scheduling module, the system is used for carrying out weight calculation on various communication services and wireless network resources according to a set processing mode for a 5G mobile phone user in an urban center environment, carrying out slice scheduling processing according with service priorities, slicing physical network resources by acquiring layout data and network link data of a 5G mobile communication base station in real time, a communication service priority order is obtained as a resource scheduling result, a resource scheduler uses the result to obviously reduce the number of blocking and switching times of a base station, meanwhile, the number of user connections and the total bandwidth occupancy can also be kept at high values for a long time, and the base station coverage rate, the single-slice bandwidth occupancy rate and the single-slice user occupancy rate are stable and have no significant fluctuation. The overall utilization rate of wireless resources of the 5G base station can be greatly improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a 5G network slicing system serving the city center environment. Background technique [0002] With the rapid development of the fifth-generation mobile communication technology (5G), the usage rate of 5G mobile phones is increasing. The design goal and most notable feature of 5G is to meet the various needs of users such as speed, delay, reliability, and traffic density. The corresponding application scenarios can be subdivided into enhanced mobile broadband (Enhance Moblie BroadBoand, eMBB), ultra-reliable Ultra Reliable Low Latency Communication (uRLLC), Massive Machine Type Communication (MassiveMachnice Type Communication, mMTC). As the five main communication service types of 5G mobile network: real-time conversational service, streaming service, interactive service, background service, and best-effort service, they need to be applied in various urban environm...

AI Technical Summary

Problems solved by technology

[0003] Existing network slicing methods, such as dynamic slicing, state slicing, predictive slicing, etc., cannot meet the following functions required by 5G users: 1. Automatically calculate the traffic when communication services are not suitable for a certain area in the city center Priority to ensure transmission efficiency; 2. Automatically judge whether the user is in the service setting scene, and carry out weight distribution for various scenes; 3. The importance of communication services can be prioritized according to the corresponding basis
