Device Location Server for EPE Positioning in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately determining the position of Enterprise Premises Equipment (EPEs) within enterprise networks, especially during emergencies, due to limited measurements from Access Points and the need for seamless transition between indoor and outdoor positioning.
Innovation Solution
A Device Location Server (DLS) is implemented in the enterprise network to communicate with EPEs, track their position, and provide connectivity using multiple subscription credentials, combined with sensors and beacon data for continuous tracking, enabling accurate positioning and emergency response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wireless positioning methods are used in enterprise networks, then the system structure remains simple, but the positioning accuracy deteriorates due to limited measurements from Access Points
Solution Approach 1:
The patent introduces a Location Server as an intermediary component that receives measurement data from multiple Access Points and processes it to determine the EPE's position. This mediator consolidates the measurement results and applies positioning algorithms, thereby improving positioning accuracy without requiring complex direct measurements between all APs and the EPE simultaneously.
Solution Approach 2:
The system performs preliminary actions by having EPEs report their status and location information to the Location Server in advance. The server maintains a database of EPE locations and can quickly retrieve and process this information when needed, reducing the complexity of real-time positioning calculations while maintaining high accuracy.
2Loss of time
If continuous tracking of EPEs is implemented, then the response time to emergencies is reduced, but the energy consumption increases
Solution Approach 1:
The patent implements periodic tracking where EPEs transmit their location and status information at predetermined intervals rather than continuously. This periodic reporting mechanism maintains situational awareness for emergency response while significantly reducing the energy consumption compared to continuous real-time tracking, as the EPEs can remain in lower-power states between reporting cycles.
3Reliability
If multiple subscription credentials are used for connectivity, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The Location Server is designed with multi-functionality, handling multiple subscription credentials and communication protocols through a single unified system. This universal approach allows the server to manage diverse connection types (e.g., Wi-Fi, cellular, satellite) without requiring separate specialized systems for each credential type, thereby improving connection reliability while limiting the increase in overall system complexity.

AI summary
Systems and methods for determining the position of EPEs (Enterprise Premises Equipment) in a wireless communication system. The disclosed method and apparatus assists emergency personal determine the position of an EPE in an enterprise network and respond to an emergency. EPE location tracking in accordance with the disclosed method is initiated without requiring public emergency calling procedures. Therefore, the method does not involve talking to the PSAP (Public Safety Answering Point) and typically does not require a real person to call. If individuals make an emergency call, such calls are be handled independently of the positioning procedure of the disclosed method.
