Base Station Function Deployment via Dynamic Resource Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, the configuration of transmission resources for base stations using the Common Public Radio Interface (CPRI) often results in either resource wastage or insufficient resources, affecting service performance due to mismatched bandwidth requirements between Baseband Units (BBU) and Remote Radio Units (RRU).
Innovation Solution
A method and device for deploying base station functions by splitting them into two groups based on available transmission resources, ensuring that the computing and transmission resources required for data transmission between these groups do not exceed available resources, allowing for dynamic adjustment based on changing load and resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission resource is configured based on maximum transmission requirement during base station deployment, then service performance is ensured, but transmission resource waste occurs when actual requirement is lower
Solution Approach 1:
The patent applies dynamics by enabling flexible function deployment that can be adjusted based on actual transmission resource conditions. The base station functions are divided into different deployment scenarios (first scenario with sufficient resources, second scenario with limited resources) allowing the system to dynamically adapt its configuration to match actual requirements rather than always using maximum resource allocation.
Solution Approach 2:
The patent changes the deployment parameter of base station functions based on transmission resource conditions. By determining whether to deploy certain functions on the BBU or RRU based on available transmission resources, the system adjusts its configuration parameters to optimize resource utilization while maintaining service performance.
2Reliability
If transmission resource is configured based on maximum transmission requirement during base station deployment, then service performance is ensured, but device complexity increases due to rigid configuration
Solution Approach 1:
The patent introduces dynamic configuration capability that allows the base station to adapt its function deployment based on actual transmission resource conditions. This reduces the need for complex manual configuration by enabling automatic adaptation to different resource scenarios.
Solution Approach 2:
The patent creates a universal deployment framework that can handle multiple scenarios (sufficient resources, limited resources) using a unified approach. The same base station hardware can flexibly support different function deployment configurations based on transmission resource availability, reducing the need for multiple specialized configurations.
3Ease of operation
If base station functions are deployed without considering available transmission resource, then deployment simplicity is maintained, but transmission resource insufficiency or waste occurs
Solution Approach 1:
The patent performs preliminary determination of transmission resource conditions before deploying base station functions. By first assessing the available transmission resources and then deciding the appropriate function deployment configuration, the system ensures optimal resource utilization while maintaining operational simplicity through automated decision-making.
Solution Approach 2:
The base station system performs self-assessment of transmission resource conditions and automatically determines the appropriate function deployment configuration without requiring external intervention. This self-service capability optimizes resource utilization while maintaining deployment simplicity.

AI summary
This application provides a base station function deployment method and device. The base station includes at least a first radio center system RCS and a first radio remote system RRS. The method includes: obtaining a selected split manner that matches an available transmission resource between the first RRS and the first RCS, where the selected split manner is used to split functions of the base station into a first function group and a second function group; and deploying, on the first RCS, a base station function that is included in the first function group and that is determined based on the selected split manner, and deploying, on the first RRS, a base station function that is included in the second function group and that is determined based on the selected split manner.
