Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack the ability to provide accurate and reliable location-based services, particularly in indoor or obstructed environments, and fail to consistently determine precise three-dimensional locations within wireless communication networks, which is inadequate for modern consumer demands and emergency services.
Innovation Solution
The implementation of enhanced location-based services (eLBS) in fixed wireless devices, which determine their location using information from other devices, forming communication groups, and dynamically deciding on resource leases based on precise location calculations, including three-dimensional coordinates and satellite signal availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile devices use traditional GPS receivers for location determination, then location services can be provided, but location accuracy is insufficient in indoor or obstructed environments
Solution Approach 1:
The patent combines multiple location determination methods (GPS, Wi-Fi positioning, cellular tower triangulation, and peer-to-peer device positioning) into a unified location service system. This allows the system to switch between or combine different positioning technologies depending on environmental conditions, thereby maintaining high location accuracy both outdoors and in indoor/obstructed environments.
Solution Approach 2:
The patent introduces location server and network infrastructure as intermediaries that facilitate position determination when direct GPS signaling is unavailable. The server collects location data from multiple sources (including other mobile devices in proximity) and computes position information, serving as a mediator that enables reliable location services in environments where traditional GPS fails.
2Measurement precision
If mobile devices determine location independently using GPS, then location information can be obtained, but precision is insufficient for modern consumer demands and emergency services
Solution Approach 1:
The patent divides the location determination function into multiple independent modules: GPS receiver module, Wi-Fi positioning module, cellular positioning module, and peer-to-peer positioning module. Each module handles specific positioning tasks, and the system selects or combines results based on availability and accuracy requirements. This segmentation allows high precision without requiring a single complex monolithic system.
Solution Approach 2:
The patent designs the mobile device with multi-functional positioning capabilities that can operate independently or in combination. The same device can use GPS when outdoors, switch to Wi-Fi or cellular positioning when indoors, or use peer-to-peer positioning when other methods are unavailable. This universal approach achieves high precision across diverse scenarios without proportionally increasing device complexity.
3Productivity
If communication resources are allocated statically in wireless networks, then network management is simplified, but resource utilization is inefficient for dynamic location-based services
Solution Approach 1:
The patent implements dynamic resource allocation where communication resources (bandwidth, processing power, memory) are automatically adjusted based on real-time location service requirements. When location determination is active and requires high precision, the system allocates additional resources to positioning modules and increases data transmission frequencies. When location services are inactive or require minimal precision, resources are reduced or reallocated to other functions, optimizing overall network productivity.

AI summary
Methods, devices and systems for generating enhanced location information on or about a wireless device. A fixed wireless device (e.g., fixed infrastructure device) may be configured to determine its current location based on location information received from one or more other devices. For example, the fixed wireless device may determine its current three-dimensional location based on latitude coordinate values, longitude coordinate values, and altitude coordinate values received from a plurality of the devices that are in proximity to the fixed wireless device. The fixed wireless device may then dynamically determine whether the fixed wireless device should be included in a telecommunication resource lease based on its determined current location. The fixed wireless device may allocate its available radio frequency resources use by devices that subscribe to a different network in response to determining that it should be included in the telecommunication resource lease.
