Wireless Base Station Parameter Optimization Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless base station networks, especially in LTE systems, simultaneous optimization of wireless parameters by multiple eNBs can lead to suboptimal results due to lack of coordination, where one eNB may adjust parameters without considering the optimization state of neighboring eNBs, resulting in inappropriate wireless parameter settings and potential service disruptions.
Innovation Solution
A wireless base station with a wireless-parameter control unit and a determination unit that checks if neighboring eNBs are performing optimization before adjusting its own parameters, ensuring that optimization is only performed if the neighboring eNBs are not already doing so, thereby avoiding conflicts and ensuring optimal parameter settings.

Engineering Contradiction Analysis
1Productivity
If multiple eNBs perform wireless-parameter optimization simultaneously without coordination, then each eNB can independently optimize its parameters, but the optimization results become suboptimal and may cause service disruptions
Solution Approach 1:
The determination unit monitors the optimization execution state of neighboring eNBs by receiving notification signals and uses this feedback information to decide whether to proceed with optimization. This feedback mechanism prevents simultaneous optimization conflicts while maintaining efficient network optimization
Solution Approach 2:
Before performing wireless-parameter optimization, the eNB checks the optimization state of neighboring base stations in advance. This preliminary check allows the system to avoid conflicting optimizations and ensures network stability before parameter changes are applied
2Ease of operation
If an eNB performs optimization without checking neighboring eNBs' optimization state, then the optimization process is simple and fast, but conflicting optimizations occur leading to inappropriate parameter settings
Solution Approach 1:
A determination unit acts as an intermediary between the optimization control unit and the parameter adjustment mechanism. It checks the optimization state of neighboring eNBs and mediates whether optimization should proceed, ensuring accurate parameter settings without complicating the overall optimization process
3Reliability
If the eNB checks neighboring eNBs' optimization state before optimization, then optimization conflicts are avoided, but the operation becomes more complex
Solution Approach 1:
Each eNB autonomously determines whether to perform optimization by checking its own neighboring base stations' optimization state through received notification signals. This self-service approach enables coordinated optimization without requiring complex centralized control mechanisms

AI summary
In order to set optimal wireless parameters, a wireless base station includes: a wireless parameter control unit (402) configured to determine whether it is necessary to perform wireless parameter optimization in an own wireless base station; and a determination unit (404) configured to determine whether another wireless base station performs wireless parameter optimization in the another wireless base station when the wireless parameter control unit determines that it is necessary to perform the wireless parameter optimization. The wireless parameter control unit (402) performs wireless parameter optimization in the own wireless base station when the determination unit determines that the another wireless base station does not perform wireless parameter optimization in the another wireless base station. The wireless parameter control unit cancels to perform wireless parameter optimization in the own wireless base station when the determination unit determines that the another wireless base station performs wireless parameter optimization in the another wireless base station.
