Mobile Location System Skew Adjustment for Private Address Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular wireless networks, the mobile location system (MLS) may determine a UE's location inaccurately, leading to the coincidence with an existing location of another entity, resulting in the dispatch of unwanted services or content to that location.
Innovation Solution
The MLS adjusts the determined UE location to avoid coinciding with existing locations, such as private addresses, by identifying alternative locations like road segments, geodetic markers, or property boundaries, and provides the adjusted coordinates to requesting entities.

Engineering Contradiction Analysis
1Productivity
If the MLS uses low-accuracy location determination processes (such as cell sector centroid or base station location), then the location determination can be performed quickly and with simple processes, but the determined location may coincide with existing locations of other entities, causing harmful dispatch errors
Solution Approach 1:
The system performs preliminary actions by checking whether the determined location coincides with existing locations of other entities before finalizing the location determination. This preliminary check prevents dispatch errors by identifying potential conflicts early in the process, allowing the system to adjust the location or flag it for review before any harmful actions are taken.
Solution Approach 2:
The system implements feedback by comparing the determined location against a database of existing entity locations and using this information to adjust or validate the location determination. When a coincidence is detected, the feedback mechanism triggers location adjustment or alternative determination methods, improving reliability without completely abandoning the efficient low-accuracy processes.
2Reliability
If the MLS adjusts the determined location to avoid coinciding with existing entity locations, then dispatch errors are reduced, but additional processing steps are required
Solution Approach 1:
The system extracts the conflict detection and resolution functionality as a separate, modular component that operates independently from the core location determination process. This allows the adjustment mechanism to be added without fundamentally redesigning the entire system, managing complexity by isolating the additional processing steps to a specific subroutine that only activates when needed.

AI summary
A mobile location system (MLS) may receive a request to provide a representative location of a user equipment device (UE). In response to receiving the request, the MLS may apply a location determination process so as to determine a location of the UE. The MLS may then determine that the determined location of the UE coincides with an existing location of another entity, such as a private address. In response to determining that the determined location of the UE coincides with the existing location of the other entity, the MLS may adjust the determined location to not coincide with the existing location of the other entity. The adjusted determined location may be a road segment, geodetic marker, or property boundary. The MLS may then provide a response to the request, in which the response identifies the adjusted determined location of the UE as the representative location of the UE.
