Code stream transmission method and device based on 5GSA network

Abstract

The invention discloses a code stream transmission method and system based on a 5GSA network. The method comprises the following steps: acquiring an original code stream of a control plane based on alarge-area center; returning the original code stream; collecting an original code stream of a data surface; and transmitting the control plane original code stream and the data plane original code stream from the provincial companies to related systems subordinate to the provincial companies. After the NVF of the core network is centralized, network elements of the core network are deployed on the cloud platform in a virtual machine mode, the problem that a traditional 3 / 4G physical port-based light splitting mode is not applicable is solved by adopting a TOR mirror image and light splittingcollection mode, and a mode of distributing and returning large-area original code streams to provincial companies is also adopted. The problems that 5G control plane data is intensively deployed in alarge area system and the control plane data is not in a local machine room are solved, finally, an SDTP protocol is adopted for packaging original code streams, the original code streams of different provinces are transmitted back to a provincial company through an IP network according to provincial identifiers, and it is guaranteed that the data streams can be safely and stably transmitted in the network.

Description

technical field [0001] This specification relates to the technical field of data transmission, in particular to a 5GSA network-based code stream transmission method and system. Background technique [0002] In the existing 5GSA (5G Standaline) network environment, there is no stable and reliable original code stream for 5GSA networking (Data Rate) refers to the high and low levels of the communication port when transmitting data within 1 second The overall scheme of the data acquisition and distribution system of the number of changes, also called code rate). [0003] 5G adopts network virtualization, software-defined network, and service-based architecture. Traditional core network elements are deployed on the unified telecom cloud in the form of virtual machines. The traditional 3 / 4G data acquisition method based on physical port splitting of equipment will not Suitable for 5G network environment.

Problems solved by technology

[0002]In the existing 5GSA (5G Standaline) network environment, there is no stable and reliable original code stream for 5GSA networking (Data Rate refers to Within 1 second, the number of high and low level changes of the communication port when transmitting data, also called the code rate) the overall scheme of the data acquisition and distribution system

[0003]5G adopts network virtualization, software-defined network and service-based architecture. Traditional core network elements are deployed on the unified telecom cloud in the form of virtual machines. Traditional The 3 / 4G data acquisition method based on the physical port splitting of the device will not be suitable for the 5G network environment

The 5G control plane adopts the SBA (Service Based Architecture) service-oriented architecture, and adopts a regional system for deployment. Several large provinces form a large-scale centralized deployment, while the UPF (User Plane Function) on the data plane adopts a sinking mechanism. When sinking to prefectures, cities or even districts and counties, the collection and distribution scheme of the original code stream will be very different from the collection and distribution of traditional core networks such as 4G, so the existing collection scheme cannot be applied to the current 5GSA network environment
