Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In broadband wireless networks, inadequate cell coverage and improper signal levels due to environmental factors lead to unwanted signal penetration between neighboring base stations, affecting end-user service quality and operational costs.
Innovation Solution
A method and system that utilize a signal penetration computing device to receive measurement reports from User Equipment (UEs), determine the location of UEs, calculate distances between them, define penetration areas, and assess signal penetration using Reference Signal Received Power (RSRP) values, with the option to filter neighbor base stations and predict signal penetration in unoccupied areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations are deployed with overlapping coverage areas to maintain call continuity, then service quality is improved, but unwanted signal penetration into neighboring base station coverage areas occurs
Solution Approach 1:
The patent changes the parameter of overlap coverage threshold dynamically. Instead of using a fixed threshold, the system adjusts the overlap coverage threshold based on measured signal penetration levels and environmental conditions. When signal penetration is detected to be harmful, the threshold is reduced to minimize overlap; when conditions allow, the threshold is increased to maintain call continuity. This resolves the contradiction by making the overlap parameter adaptive rather than static.
Solution Approach 2:
The patent implements a feedback mechanism where signal penetration is continuously monitored and measured in real-time. The measurement results are fed back to the base station controller, which then adjusts the overlap coverage threshold accordingly. This closed-loop feedback system allows the network to automatically respond to changing conditions and maintain optimal performance, resolving the contradiction between maintaining call continuity and preventing harmful signal penetration.
2Ease of manufacture
If standard mechanisms are used to design overlap zones, then initial coverage is established, but actual field conditions like landscape and environment cause improper signal levels and unwanted penetration
Solution Approach 1:
The patent performs preliminary measurement of signal penetration and environmental conditions during the network planning and deployment phase. Before full operation begins, the system collects data about actual field conditions including landscape features and environmental factors. This preliminary action allows the overlap coverage threshold to be pre-adjusted to account for local conditions, improving measurement precision while maintaining ease of initial deployment.
Solution Approach 2:
The patent adjusts the overlap coverage threshold parameter based on measured environmental factors such as landscape obstructions, reflections, noise, humidity, and wind. Instead of using a one-size-fits-all standard mechanism, the system modifies the threshold parameter for different geographic locations and environmental conditions. This allows accurate signal level control in diverse real-world settings while maintaining relatively simple deployment procedures.
3Measurement precision
If measurement reports from UEs are collected to determine signal penetration, then accurate penetration assessment is achieved, but system complexity and processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for penetration assessment from UE measurement reports. Instead of processing all available measurement data, the system selectively extracts RSRP values and location information that are directly relevant to determining signal penetration. This extraction approach maintains measurement precision while significantly reducing processing complexity by focusing only on critical parameters.
Solution Approach 2:
The patent uses existing UE measurement reports and location information that are already generated for other purposes (such as handover decisions and mobility management). Rather than implementing a completely new measurement and reporting system, the invention reuses these existing data copies for penetration assessment. This approach achieves accurate penetration measurement without the complexity of building a separate dedicated measurement infrastructure.
