Femtocell Management Entity Location Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the location of a device using femtocell information are limited by the need for accurate GNSS coordinates, RSSI, and power levels, which are prone to interference and lack efficient management, especially in dense urban areas with overlapping frequency usage.
Innovation Solution
A femtocell management entity receives and processes GNSS coordinates, RSSI, and power levels from multiple femtocells to determine the location of communication devices, utilizing triangulation and registry updates for precise mapping and location services, while managing potential interference and access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If femtocell data integration is used for location determination, then location accuracy is improved, but system complexity increases
Solution Approach 1:
A femtocell management entity is introduced as an intermediary component that centralizes the collection, processing, and management of femtocell data. This mediator handles the complexity of integrating GNSS coordinates, RSSI, and power level information from multiple femtocells, while presenting a simplified location determination service to communication devices. The management entity acts as the intermediary that resolves the complexity issue by consolidating data processing functions.
2Area of stationary object
If multiple femtocells are deployed in dense urban areas, then coverage is improved, but interference increases
Solution Approach 1:
The system implements feedback mechanisms where the femtocell management entity continuously monitors RSSI and power level data from deployed femtocells. Based on this feedback information, the system can identify interference patterns and adjust femtocell configurations, such as modifying transmission power levels or optimizing frequency assignments. This feedback loop enables the system to maintain improved coverage in dense urban areas while actively managing and reducing interference through data-driven adjustments.
3Reliability
If femtocell management and registry updates are implemented, then service reliability is improved, but processing requirements increase
Solution Approach 1:
The femtocell management entity performs preliminary actions by pre-processing and organizing femtocell data, including GNSS coordinates and signal characteristics, before location determination is actually requested. Registry updates are performed in advance to maintain current information about femtocell deployments and configurations. This preliminary organization of data reduces the processing burden during actual location queries, as the management entity can quickly retrieve and utilize pre-processed information rather than computing everything in real-time.
