Distributed Unit Resource Collaboration Without CU Signaling
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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

3Reliability
If centralized management by CU is used, then unified control is achieved, but processing delay increases
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
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

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.
