O-RAN Zero-Touch Provisioning for Automated Component Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing O-RAN implementations lack efficient zero-touch provisioning (ZTP) mechanisms for automating the deployment and updates of network components, leading to potential human intervention and errors in hardware and software configurations.
Innovation Solution
A computer system is configured to perform zero-touch provisioning (ZTP) by generating a ZTP request, obtaining a payload, determining operations, and distributing it to components in the O-RAN, utilizing reference data for network topology and inventory information to automate the deployment and updates of RUs, DUs, CUs, and other network functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual provisioning methods are used for O-RAN components, then human intervention allows flexible configuration, but errors and inefficiency increase in hardware and software deployments
Solution Approach 1:
The system enables self-service provisioning where the O-RAN components automatically receive and process configuration data through the ZTP mechanism. The computer system autonomously determines provisioning operations, distributes configuration payloads, and executes updates without requiring human intervention, thereby reducing both errors and provisioning time
Solution Approach 2:
The system performs preliminary actions by pre-configuring provisioning payloads and preparing configuration data before actual deployment. The computer system determines the necessary provisioning operations in advance and has the configuration payloads ready for distribution, enabling faster and more accurate deployment when the actual provisioning is triggered
2Productivity
If automated ZTP mechanisms are implemented, then provisioning speed increases, but system complexity increases
Solution Approach 1:
The computer system is designed with multi-functionality to handle various provisioning operations across different O-RAN components (RUs, DUs, CUs, network functions). A single automated ZTP mechanism manages configuration, updates, and provisioning for multiple component types, increasing productivity while containing complexity through unified management rather than separate systems for each component
Solution Approach 2:
The system introduces an intermediary computer system that acts as a mediator between the provisioning requests and the O-RAN components. This intermediary handles the complexity of automated provisioning operations, translating high-level provisioning needs into specific configuration actions, thereby enabling automated high-speed provisioning without requiring each component to have complex built-in provisioning logic
3Reliability
If manual configuration updates are performed, then system complexity remains low, but error rates increase and compliance with O-RAN standards becomes difficult to ensure
Solution Approach 1:
The system implements feedback mechanisms where the computer system monitors the provisioning operations, tracks configuration updates, and verifies compliance with O-RAN standards. This feedback loop ensures that configuration accuracy is maintained through automated verification and correction, improving reliability while the automation itself handles the operational complexity

AI summary
In various embodiments, zero touch provisioning (ZTP) in a cloud based 5G system are provided. In some embodiments, the ZTP includes receiving a request to perform ZTP on the component in the 5G system; generating a ZTP request based on the request; obtaining a ZTP payload according to the ZTP request; determining one or more ZTP operations based on the ZTP payload; determining instances of the component in the 5G system for the ZTP operations; distributing the ZTP payload to the first and second instances of the component in the 5G system to carry out the ZTP operations; determining one or more results of the ZTP operations; generating feedback information based on the one or more results of the ZTP operations.
