Positioning Node Triggering Idle Device Registration for Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular network positioning methods are not effective for idle mode wireless devices and lack accuracy in detecting user proximity across borders, and dedicated positioning mechanisms are not universally supported or accurate enough.
Innovation Solution
Introduce a dedicated communication infrastructure node that broadcasts system information to trigger registration requests from idle mode wireless devices, which are then rejected, causing the devices to transition to connected mode for measurement reporting, allowing proximity determination based on known geographical locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing cellular network positioning methods are used, then the system maintains simplicity and compatibility, but positioning accuracy for idle mode devices and cross-border proximity detection deteriorates
Solution Approach 1:
The patent introduces a dedicated positioning node as an intermediary component between wireless devices and the core network. This node specifically handles positioning tasks for idle mode devices by broadcasting system information and processing registration requests, thereby improving positioning accuracy without complicating the overall network architecture. The positioning node acts as a specialized mediator that bridges the gap between simple cellular infrastructure and precise location detection needs.
Solution Approach 2:
The patent segments the network functionality by separating positioning operations from general communication services. The dedicated positioning node handles only positioning-related tasks such as broadcasting system information, receiving registration requests, and determining proximity, while the core network continues to handle communication services. This segmentation allows each component to be optimized for its specific function, improving overall positioning accuracy without burdening the entire system with increased complexity.
2Measurement precision
If dedicated positioning mechanisms are introduced, then positioning accuracy improves, but device compatibility and universal support deteriorate
Solution Approach 1:
The dedicated positioning node is designed with universal functionality that works across different device types and network configurations. It uses standard cellular communication protocols for broadcasting system information and processing registration requests, ensuring compatibility with various wireless devices while providing enhanced positioning capabilities. The node's multi-functional design allows it to serve both positioning purposes and maintain broad device support without requiring proprietary or device-specific implementations.
Solution Approach 2:
The positioning node replicates essential network functions (broadcasting system information, processing registration requests) that devices already expect from regular base stations. By copying these familiar communication patterns, the node ensures device compatibility while adding specialized positioning capabilities. Devices interact with the positioning node using standard procedures they already support, thereby maintaining universal adaptability while achieving improved proximity detection accuracy.
3Measurement precision
If idle mode devices are triggered to connect for positioning, then positioning capability improves, but network load and signaling overhead increase
Solution Approach 1:
The system applies partial action by triggering only the minimum necessary connection activity for positioning purposes. Idle mode devices are prompted to establish brief connections with the positioning node solely to exchange positioning-related signaling (system information reception and registration request/response), rather than full communication sessions. This partial action provides sufficient positioning capability while limiting the energy consumption and network load to the essential minimum required for location detection.
Solution Approach 2:
The positioning process is executed rapidly by skipping unnecessary intermediate steps. The dedicated positioning node efficiently triggers idle mode devices to connect, performs the positioning measurement through streamlined signaling exchange, and returns devices to idle mode quickly. This rushing through of the positioning procedure minimizes the duration of connected mode activity, thereby reducing network energy consumption and signaling overhead while still achieving accurate proximity detection.

AI summary
The present inventive concept relates to a node for use in positioning of a wireless unit, the node comprising: a transmitter arranged to broadcast system information arranged to trigger a registration, the system information comprising a first registration area code; a receiver arranged to receive registration requests from wireless devices in receipt of the system information, wherein the node is arranged to, in response to a registration request received from any wireless device in receipt of the broadcasted system information, transmit, via the transmitter, a response to said any wireless device indicating that the registration request is rejected, and change the first registration area code to a second registration area code when a registration area code update condition is met.
