Solution Overview
Problem
Existing location-based services face challenges in selecting the most appropriate location determination technique for specific requests, as current methods do not effectively consider criteria such as cost, quality of service, and resource capabilities of mobile devices and networks.
Innovation Solution
A software and/or hardware facility that selects a location determination technique from multiple options based on criteria like cost, desired quality of service, and resource capabilities, weighting these criteria according to their importance for the specific request, and employing the selected technique to determine the mobile device's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple location determination techniques are employed, then location accuracy and service quality are improved, but system complexity and resource consumption increase
Solution Approach 1:
The patent changes the parameters of location determination techniques by introducing multiple selectable methods (GPS, network-based, hybrid) with different characteristics. The system evaluates and selects techniques based on varying parameters such as cost, power consumption, accuracy requirements, and availability, thereby resolving the contradiction by allowing high accuracy when needed while avoiding unnecessary complexity when lower accuracy suffices.
Solution Approach 2:
The patent implements dynamic selection of location determination techniques based on real-time conditions. The system continuously evaluates available techniques and their parameters (cost, power, accuracy) and dynamically switches between them according to current service requirements and device state, thus achieving high accuracy when necessary while maintaining simplicity and efficiency in other scenarios.
2Measurement precision
If high-accuracy location determination techniques are used, then location quality is improved, but cost and power consumption increase
Solution Approach 1:
The patent introduces multiple location determination techniques with different power consumption and accuracy characteristics (e.g., GPS with high power and high accuracy, network-based methods with lower power and variable accuracy). The system selects the appropriate technique by evaluating parameters including power consumption, cost, and accuracy requirements, thereby achieving high location quality when necessary while conserving power during normal operations.
3Adaptability or versatility
If multiple location determination techniques are evaluated and selected, then service customization and adaptability are improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements preliminary evaluation and ranking of location determination techniques based on predefined criteria (cost, power consumption, accuracy, availability). By pre-establishing evaluation frameworks and technique characteristics, the system can quickly select appropriate methods without extensive real-time computation, thus achieving high service customization while minimizing processing time delays.

AI summary
A facility for selecting a location determination technique from multiple available location determination techniques in order to determine the location of a mobile device in a cost or resource efficient manner. In order to select the location determination technique, the facility may consider various criteria such as the cost of employing the techniques, quality of service (QoS) criteria, the capabilities and/or resources of given mobile devices and/or networks, and/or the like. To select the location determination technique, the facility may rank the multiple location determination techniques according to weighted criteria and select the location determination technique according to the ranking. The criteria may be weighted according to the relative importance of each criterion to a requesting location-based service.
