Neighbor Reporting Segmentation for Mobile Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large wireless communication networks, maintaining a comprehensive list of neighbor Base Stations (BS) for each Mobile Station (MS) is resource-intensive and inefficient, as it requires frequent signal strength measurements, impacting both MS and BS performance, and includes unnecessary neighbors with low potential service levels.
Innovation Solution
Categorizing MSs into groups based on signal strength, determining a primary neighbor BS for each group, and instructing MSs to report signal strength measurements only to the primary neighbor during a first time period, with global neighbor reporting occurring in a second time period, reducing unnecessary measurements and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the serving BS maintains a comprehensive neighbor list for each MS and instructs MS to report signal strength for all neighbors, then handover decision accuracy is improved, but MS battery consumption and processing load increase significantly
Solution Approach 1:
The patent segments the neighbor list into two distinct parts: a primary neighbor (single entry) and a neighbor list (multiple entries). The MS is instructed to continuously report signal strength for the primary neighbor at frequent intervals, while reporting for the full neighbor list occurs less frequently. This segmentation allows the system to maintain accurate handover decisions through continuous primary neighbor monitoring while reducing overall measurement burden and battery consumption.
Solution Approach 2:
The patent implements periodic action by instructing the MS to report signal strength measurements for the primary neighbor at every measurement opportunity (continuous monitoring), while reporting for the complete neighbor list occurs periodically at less frequent intervals. This periodic full-list reporting reduces processing load and battery consumption compared to continuous full-list reporting, while still maintaining adequate handover decision accuracy through the continuous primary neighbor data.
2Measurement precision
If the serving BS maintains a comprehensive neighbor list for each MS, then handover decision accuracy is improved, but BS processing load and operational complexity increase
Solution Approach 1:
The patent segments the neighbor reporting mechanism into two parts: primary neighbor reporting and full neighbor list reporting. The BS maintains the complete neighbor list but processes reports differently - continuously monitoring primary neighbor signal strength from all MSs while periodically processing full neighbor list reports. This segmentation reduces the BS's continuous processing load while maintaining comprehensive handover decision capability.
Solution Approach 2:
The patent extracts the primary neighbor information from the complete neighbor list and treats it separately. The BS identifies and extracts a single primary neighbor entry from each MS's neighbor list, then instructs the MS to report this primary neighbor's signal strength continuously. This extraction allows the BS to focus processing resources on the most critical handover candidate while reducing overall operational complexity.
3Measurement precision
If the MS performs frequent signal strength measurements for all neighbors, then handover decision quality is improved, but MS processing power consumption increases
Solution Approach 1:
The patent segments the measurement task into two parts: continuous measurement of the primary neighbor and periodic measurement of the full neighbor list. The MS performs frequent signal strength measurements only for the primary neighbor, which requires minimal processing power, while conducting comprehensive measurements of all neighbors less frequently. This segmentation maintains measurement accuracy for handover decisions while significantly reducing continuous processing power consumption.
Solution Approach 2:
The patent implements periodic action by having the MS perform continuous signal strength measurements for the primary neighbor at every measurement opportunity, while conducting measurements for the complete neighbor list periodically at less frequent intervals. This periodic full-list measurement approach reduces processing power consumption compared to continuous full-list measurements, while maintaining adequate measurement accuracy through the continuous primary neighbor monitoring.

AI summary
A method, neighbor relation maintenance device, and non-transitory computer readable medium for neighbor reporting in a wireless communication network is disclosed. The method comprises categorizing, by a neighbor relation maintenance device, a plurality of Mobile Stations (MSs) into one or more groups. A primary neighbor BS for each group of the one or more groups of MSs is determined. Each MS of each group is instructed to report signal strength measurements between the each MS and the corresponding primary neighbor BS associated with the each group in a first time period. Each MS of each group is instructed to report signal strength measurements between the each MS and each neighbor BS in a predefined neighbor list associated with the each MS in a second time period.
