Mobile Station Location Request with Embedded Base Station Delay Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cellular wireless communication systems experience latency in responding to location-based service requests due to the communication overhead involved in requesting and receiving base station delay measurements from mobile stations.
Innovation Solution
Incorporating base station delay measurements into the mobile station's initial location-based service request, allowing the positioning system to triangulate the mobile station's location without needing to request these measurements separately, thereby reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the positioning system requests base station delay measurements from the mobile station separately, then the location determination can be performed with sufficient accuracy, but the latency in responding to location-based service requests increases due to additional communication overhead
Solution Approach 1:
The mobile station performs preliminary action by including base station delay measurements in the initial location-based service request message before the positioning system needs to process the location determination. This advance preparation eliminates the need for separate measurement requests and reduces overall latency.
Solution Approach 2:
The invention merges the base station delay measurements with the location-based service request message, combining what were previously separate communication steps into a single integrated message transmission. This merging eliminates redundant communication overhead and accelerates the location determination process.
2Measurement precision
If additional communication steps are used to obtain base station delay measurements, then the positioning system can ensure accurate location triangulation, but the overall speed and efficiency of location determination decreases
Solution Approach 1:
The mobile station performs preliminary action by preparing and including base station delay measurements in the initial request message, eliminating the need for subsequent separate measurement requests and accelerating the overall location determination process while maintaining triangulation accuracy.
Solution Approach 2:
The invention extracts the base station delay measurements from the separate measurement request step and integrates them directly into the location-based service request message, removing the communication overhead while preserving the necessary data for accurate location triangulation.

AI summary
Disclosed herein is a method and system to help reduce latency in responding to a location based service request from a mobile station. According to the method, the mobile station will include base station delay measurements with the location based service request. That way, when a network entity (such as the location based service provider, or a proxy between the mobile station and the location based service provider) receives the mobile station's request for a location-based service, the entity may readily convey the provided base station delay measurements to the positioning system to enable the positioning system to triangulate the mobile station's location without the need to request the base station delay measurements from the mobile station.
