Mobile Device Radio Model Availability Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location determination methods for mobile devices face inefficiencies due to the need for substantial memory and bandwidth to store and update radio models, and servers may lack necessary models for precise location estimation, leading to unnecessary resource consumption when models are outdated or unavailable.
Innovation Solution
A method that determines the availability of radio models before sending location information to a server, allowing the device to assess whether a positioning request can be successfully made based on the availability of models, thereby avoiding unnecessary bandwidth and processing resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device stores radio models locally, then location determination can be performed without network communication, but substantial memory and bandwidth are consumed
Solution Approach 1:
The patent extracts the radio models from the mobile device and stores them on the network server instead. The mobile device only retains minimal information needed to request location services, while the server maintains the substantial radio model data structures. This extraction resolves the contradiction by eliminating local memory requirements and reducing bandwidth consumption for model updates.
Solution Approach 2:
The network server acts as an intermediary between the mobile device and the radio models. Instead of the mobile device directly storing and managing radio models, it communicates with the server which handles model storage, maintenance, and provision. This intermediary approach allows the mobile device to perform location determination without substantial local memory while maintaining reliable access to current radio models.
2Reliability
If the server maintains radio models for on-line positioning, then mobile devices can perform location determination with network support, but the server may lack necessary models leading to unnecessary resource consumption
Solution Approach 1:
The patent implements preliminary action by having the mobile device check for the availability of radio models on the server before initiating a full location determination request. The device queries the server to confirm that current radio models exist for its current location, and only proceeds with resource-intensive positioning operations when models are confirmed to be available. This preliminary check prevents wasteful consumption of bandwidth and processing resources when models are outdated or unavailable.
3Measurement precision
If radio models are frequently updated to maintain accuracy, then location determination precision improves, but bandwidth consumption increases
Solution Approach 1:
The patent implements feedback by having the mobile device check with the server before each location determination to confirm that updated radio models are available. The server provides feedback about model availability and currency, allowing the device to intelligently decide whether to proceed with positioning requests. This feedback mechanism ensures location accuracy is maintained through updates while avoiding unnecessary bandwidth consumption when models have not changed or are unavailable.
