Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In UTRAN networks, accurately predicting CP/UP capability requirements is challenging, leading to inefficient resource allocation, waste, and service interruptions due to manual intervention and long adjustment cycles.
Innovation Solution
A method and apparatus for automatically adjusting physical resources based on load statuses of CP and UP, calculating the quantity of to-be-adjusted resources, and reallocating them to balance workloads, thereby optimizing resource utilization and reducing overload possibilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If physical resources are allocated based on predictions, then resource allocation can be planned in advance, but prediction accuracy is difficult to achieve leading to resource waste or insufficiency
Solution Approach 1:
The system automatically monitors its own resource usage and dynamically adjusts physical resource allocation between CP and UP based on real-time load information, eliminating the need for external predictions and manual intervention. The controller autonomously collects load data, calculates required resources, and performs adjustments without human involvement.
Solution Approach 2:
The system continuously collects real-time load information from CP and UP boards, compares current resource allocation with actual workload demands, and dynamically adjusts resource distribution accordingly. This closed-loop feedback mechanism ensures resource allocation matches actual needs without relying on inaccurate predictions.
2Productivity
If manual intervention is used for resource adjustment, then flexibility can be maintained, but service interruption occurs and adjustment efficiency is reduced
Solution Approach 1:
The controller automatically performs resource adjustment operations without requiring manual intervention. It collects load information, calculates resource requirements, and executes allocation changes autonomously, eliminating service interruptions caused by manual operations while maintaining optimal resource distribution.
Solution Approach 2:
The system replaces manual mechanical adjustment operations with automated electronic control. The controller uses software-based resource allocation mechanisms to dynamically adjust physical resources, substituting human operators with automated algorithms that maintain service continuity while improving adjustment efficiency.
3Adaptability or versatility
If separate physical boards are used for CP and UP, then functional separation is achieved, but resource utilization efficiency decreases and waste increases
Solution Approach 1:
The system merges previously separate CP and UP physical resources into a unified pool that can be dynamically shared. By allowing both control plane and user plane functions to access the same physical resources according to real-time load demands, the system achieves both functional separation (through logical partitioning) and resource consolidation, eliminating waste while maintaining adaptability.
Solution Approach 2:
Physical resources are designed to serve multiple purposes - the same physical boards can function as CP boards or UP boards depending on real-time workload requirements. This multi-functionality allows resources to be dynamically reassigned between control and user plane functions, maximizing utilization efficiency while maintaining the ability to handle different operational scenarios.

AI summary
Embodiments of the present invention provide a physical resource adjustment method and apparatus, where the method includes: collecting load information of a control plane CP and a user plane UP, and performing calculation, according to the corresponding load information, to obtain a load of the CP in the case that the CP is busy and a load of the UP when the UP is busy; calculating a quantity of to-be-adjusted physical resources in the case that the load of the CP when the CP is busy and the load of the UP when the UP is busy meet a preset balancing adjustment condition; and adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources that is obtained through calculation. By means of the present invention, a physical resource can be adjusted and allocated automatically according to load statuses of a CP and a UP, so that the CP and the UP share a physical resource, thereby balancing a load of a device, promoting usage of the device, and reducing a possibility that the CP and the UP are overloaded.
