Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks are inefficient in dynamically changing parameters for location services, particularly in scenarios like WLAN-WAN interworking, where the frequency of location requests should adapt based on the mobile station's location, velocity, and environmental conditions, but existing specifications do not allow for real-time adjustments without initiating a new request.
Innovation Solution
A network entity with a controller that can initiate and modify location reporting sessions, including changing the periodicity and quality of service, dynamically based on the mobile station's current location, velocity, and other conditions, allowing for efficient adaptation of location request parameters during ongoing sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If periodic location requests are made with constant parameters as specified by current specifications, then the location service can be provided reliably, but the system cannot adapt to changing conditions such as mobile station velocity and environmental factors, leading to inefficient resource usage
Solution Approach 1:
The patent applies dynamics by enabling the location-based application to dynamically modify parameters (such as periodicity, accuracy requirements) of ongoing location requests based on real-time conditions like mobile station velocity and environmental factors, rather than using static pre-configured parameters. This allows the system to adapt location request characteristics to current operational context, reducing unnecessary requests when the mobile station is stationary or in low-change environments.
Solution Approach 2:
The patent implements parameter changes by allowing modification of location request parameters (periodicity, accuracy, reporting intervals) during the execution of a location request session. The system can adjust these parameters based on detected changes in mobile station velocity, location quality of service requirements, and environmental conditions, thereby optimizing resource consumption while maintaining service quality.
2Measurement precision
If the frequency of location requests is increased to track mobile station position accurately in changing environments, then location accuracy is improved, but resource consumption and network load increase significantly
Solution Approach 1:
The system dynamically adjusts location request parameters including periodicity and accuracy requirements based on current conditions. When the mobile station is moving rapidly or entering new environmental contexts, the system increases request frequency and accuracy requirements. When the mobile station is stationary or in stable environments, the system reduces request frequency, thereby optimizing the balance between location accuracy and resource efficiency.
Solution Approach 2:
The patent enables dynamic adjustment of location request characteristics based on real-time velocity and environmental assessments. The system continuously monitors mobile station movement patterns and modifies location request parameters accordingly, increasing precision only when necessary for accurate tracking, thus avoiding excessive resource consumption during periods of low mobility or in stable environments.
3Speed
If location requests are made continuously with high periodicity to ensure real-time location information, then response time is reduced, but power consumption and network overhead increase
Solution Approach 1:
The patent applies dynamics by adjusting the periodicity of location requests based on real-time conditions such as mobile station velocity and environmental stability. When rapid response is needed (e.g., mobile station moving quickly, entering new service areas), the system increases request frequency. When conditions are stable or mobility is low, the system extends intervals between requests, thereby reducing power consumption while maintaining adequate response times for the current operational context.
Solution Approach 2:
The system dynamically modifies the periodicity parameter of location requests based on assessed conditions. The location-based application can increase or decrease the frequency of location requests according to mobile station velocity, environmental factors, and service requirements, optimizing the balance between response time requirements and power consumption for the mobile station.

AI summary
A network entity includes a controller adapted to operate a location-based application for initiating a location reporting session. The location reporting session includes determining and reporting a current location of a mobile station based on one or more parameters having one or more associated values, where, when the session is a periodic location reporting session, one of the parameters may be a periodicity of reporting the current location of the mobile station. The location-based application is also adapted to change the value of one or more of the parameters during the location reporting session. The same location reporting session may therefore continue based on the changed values of the respective parameter(s).
