Solution Overview

Problem

Existing radio access network architectures, such as O-RAN, face inefficiencies in deploying xAPPs due to increased traffic and communication costs between nodes, as current methods do not consider message processing information when determining node deployment.

Innovation Solution

An electronic device and method that determines xAPP deployment based on message processing information, including message size and frequency, to minimize internal traffic and communication costs within the RIC.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If xAPP is deployed to any node without considering message processing information, then deployment flexibility is improved, but internal traffic and communication costs increase

Engineering Contradiction:

Improvedeployment flexibilityVSAvoidcommunication cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system performs preliminary analysis of message processing information (message size, frequency, subscription relationships) before deploying xAPP. The RIC identifies which E2 nodes the xAPP subscribes to and selects a deployment node based on this pre-collected information, avoiding subsequent traffic optimization issues

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The deployment decision changes from random or resource-only based selection to selection based on message processing parameters. The system considers message size, message frequency, and E2 node subscription relationships as key parameters to determine the optimal deployment node, thereby reducing communication costs

Inventive Principle:

Principle #35Parameter changes

2Productivity

If xAPP deployment ignores E2 node subscription information, then deployment speed is improved, but message processing efficiency deteriorates

Engineering Contradiction:

Improvedeployment speedVSAvoidmessage processing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The RIC collects and analyzes E2 node subscription information, message size, and message frequency before deployment. This preliminary action ensures that the xAPP is deployed to a node that will minimize subsequent message processing time, avoiding the need for later re-deployment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from message processing information (subscription relationships, message characteristics) to optimize deployment decisions. By analyzing what E2 nodes the xAPP needs to communicate with, the system selects nodes that minimize communication overhead and processing time

Inventive Principle:

Principle #23Feedback

AI summary

According to various embodiments, a method of operating a radio access network intelligent controller (RIC) may include: identifying a deployment request for a first xAPP, based on the request, identifying information related to a message processed by each of at least some of a plurality of nodes executed in the RIC, and based on E2 node subscription-related information about the first xAPP, and deploying the first xAPP to a first node selected from among the plurality of nodes, based on the information related to the message processed by each of the at least some of the plurality of nodes.
