Network Node Module Movement Detection for Location Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, particularly in cellular networks, it is challenging to track and identify physical changes in network nodes, especially in Pico/Femto RBS networks where limited field operators and private customer ownership complicate the registration of node changes, leading to potential misidentification and loss of location identity.
Innovation Solution
A network node module with a movement detector and a control unit that generates an indication of physical changes by detecting movement between mating elements, allowing for simplified detection and handling of changes, including resetting module memory and initiating indication handling procedures to update location data and security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking and identification methods are used for network nodes, then field operators can configure location information, but the process becomes complex and error-prone when nodes are frequently changed or removed
Solution Approach 1:
The network node module automatically detects its own physical changes through integrated movement detectors and generates indications without requiring external field operator intervention. The system self-monitors mating element movements and self-updates location information, eliminating manual tracking complexity while maintaining reliability
Solution Approach 2:
The system implements continuous feedback by monitoring the state of mating elements and automatically generating location update indications when changes are detected. This closed-loop feedback mechanism ensures location identity accuracy by immediately responding to physical changes without manual intervention
2Measurement precision
If skilled field operators are deployed to configure and track node changes, then location information can be accurately registered, but the limited number of operators cannot service all nodes especially in femto networks
Solution Approach 1:
Each network node module autonomously detects and reports its own location changes without requiring field operator services. The movement detectors continuously monitor mating element states and automatically generate location update indications, enabling unlimited node coverage with minimal human intervention while maintaining precise location identification
Solution Approach 2:
The system divides the node monitoring function into independent, self-contained modules with integrated movement detectors. Each module independently tracks its own physical state and generates location indications, allowing parallel operation across numerous nodes without requiring centralized manual tracking resources
3Adaptability or versatility
If the entire RBS is removed from a site, then the node can be relocated or replaced, but the location identity is lost since nothing remains at the original site
Solution Approach 1:
The system creates a portable copy of the location identity stored in the removable network node module itself. When the RBS is relocated, the module carries its own location information and movement detection capabilities, automatically generating new location indications at the destination without leaving behind any physical tracking infrastructure at the original site
Solution Approach 2:
The movement detectors are pre-configured to continuously monitor mating element states and prepare location update indications in advance. When relocation occurs, the system has already detected the movement and generated the location indication, ensuring no information loss during the transition
4Reliability
If manual tracking of node changes is implemented, then changes can be registered, but the process is time-consuming and inefficient especially with frequent node changes
Solution Approach 1:
The movement detectors continuously monitor the state of mating elements without interruption, maintaining constant surveillance of physical changes. This continuous detection eliminates gaps in tracking and ensures immediate detection of any node changes, achieving both high reliability and rapid response without manual intervention delays
Solution Approach 2:
The system automatically detects and records all node changes through integrated sensors and generates indications without requiring external tracking processes. This self-monitoring capability eliminates the time-consuming manual registration process while maintaining accurate change detection through continuous automated surveillance
