Solution Overview

Problem

Current communication systems face inefficiencies in resource collaboration and increased processing delays due to signaling overheads in managing distributed units (DUs) within mobile networks.

Innovation Solution

A communication system and method that enables flexible resource collaboration management by introducing a first apparatus to manage and schedule resources of DUs, allowing direct communication between DUs and the first apparatus without the need for signaling between central units (CUs), thereby improving resource utilization and reducing processing delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If signaling transmission is used for resource collaboration negotiation between CUs, then resource collaboration can be established, but processing delay increases and resource utilization decreases

Engineering Contradiction:
Improveresource collaboration efficiencyVSAvoidprocessing delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the resource collaboration management function from the CU and places it in the DU. Each DU independently manages its own resource collaboration without needing to signal the CU, thereby eliminating the signaling delay and improving processing speed while maintaining resource collaboration efficiency

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The DU performs self-management of resource collaboration by autonomously determining when and how to collaborate with other DUs. The DU independently monitors resource status, selects collaboration partners, and executes resource sharing without external control, thereby reducing processing delay and improving efficiency

Inventive Principle:
Principle #25Self-service

2Productivity

If signaling transmission is used for resource collaboration negotiation between CUs, then resource collaboration can be established, but resource utilization decreases

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent extracts the resource collaboration management function from the CU and places it in the DU. Each DU independently manages its own resource collaboration without needing to signal the CU, thereby eliminating the signaling delay and improving processing speed while maintaining resource collaboration efficiency

Inventive Principle:

The DU independently monitors resource status, selects collaboration partners, and executes resource sharing without external control, thereby reducing processing delay and improving efficiency

Inventive Principle:

3Reliability

If centralized management by CU is used, then unified control is achieved, but processing delay increases

Engineering Contradiction:
Improveunified managementVSAvoidprocessing delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the centralized management function into distributed units. Instead of one CU controlling all DUs, each DU independently manages its own resources and collaboration. This segmentation eliminates the processing delay associated with centralized control while maintaining reliability through autonomous decision-making at each DU

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The DU performs self-management of resource collaboration by autonomously determining when and how to collaborate with other DUs. The DU independently monitors resource status, selects collaboration partners, and executes resource sharing without external control, thereby reducing processing delay and improving efficiency

Inventive Principle:
Principle #25Self-service

AI summary

A communication system and method are provided. The communication system includes a first central unit CU, a first apparatus, and at least one distributed unit DU, where the first CU may be configured to manage the first apparatus and/or a part or all of the at least one DU; and the first apparatus may be configured to manage resource collaboration of the at least one DU. In this way, resource collaboration of a DU can be implemented without signaling transmission for resource collaboration negotiation between CUs, so that resource collaboration efficiency of the DU can be improved, a processing delay of the DU can be reduced, and resource utilization of the DU can be improved.
