Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If enhanced device capability is implemented to provide accurate device-location information, then location accuracy is improved, but device complexity and processing requirements increase
Solution Approach 1:
The location determination system is segmented into multiple independent signal sources (satellites, base stations, access points) that can be individually measured and combined. Each signal source provides partial location information, and the mobile device processes these segmented measurements to achieve accurate overall location determination without requiring a single complex positioning system.
Solution Approach 2:
The mobile device utilizes multiple signal types and transmission sources that can serve different functions simultaneously. Satellite signals provide global positioning, base stations provide cellular network location, and access points provide local area positioning. This multi-functional approach allows the device to achieve accurate location determination across diverse environments using a unified measurement framework.
2Reliability
If multiple signal sources are utilized for location determination, then reliability in unpredictable environments is improved, but system complexity increases
Solution Approach 1:
The patent merges measurements from multiple independent signal sources (satellites, base stations, access points) into a unified location determination process. By combining these diverse signal sources, the system achieves reliable location determination in unpredictable environments where any single source might fail, while managing complexity through integrated processing.
Solution Approach 2:
The system dynamically changes measurement parameters by selecting which signal sources to utilize based on environmental conditions and availability. The mobile device can adjust the weight and importance of different signal sources (satellites, base stations, access points) depending on the situation, allowing reliable location determination while adapting to varying system complexity requirements.
3Measurement precision
If comprehensive signal measurement and analysis is performed, then location accuracy is improved, but processing power requirements increase
Solution Approach 1:
The mobile device performs preliminary measurements and collects signal data from multiple sources (satellites, base stations, access points) before final location calculation. This preliminary action allows the device to gather necessary measurement data in advance, reducing the computational burden during the actual location determination process and lowering instantaneous processing power requirements while maintaining high location accuracy.

AI summary
A system and method for effectively performing enhanced device location procedures to determine the current physical location of a mobile device includes a plurality of satellites that wirelessly transmit satellite beacon signals, a plurality of base stations that wirelessly transmit pilot signals, and a plurality of access points that wirelessly transmit access-point beacon signals. A location detector of the mobile device coordinates a device location procedure by measuring the satellite beacon signals, the pilot signals, and the access-point beacon signals to generate corresponding satellite information, base station information, and access point information. The location detector analyzes the satellite information, the base station information, and the access point information to select an optimal system configuration from the most effective satellites, base stations, and access points. The location detector then utilizes the optimal system configuration to accurately calculate the current physical location of the mobile device.
