Mobile Network Data Acquisition via Connection Status Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data acquisition methods in mobile radio networks face inefficiencies due to increased communication volume from vehicles, especially in scenarios involving cooperative or autonomous driving, leading to network overload, as they reserve resources based on current demand and position without considering connection status, resulting in erroneous transmissions and additional loading.
Innovation Solution
A method for collective data acquisition that selects mobile devices based on their connection status, utilizing criteria such as connection quality, spectral efficiency, and handover status, with the mobile radio operator interrogating and providing connection status data to avoid individual device inquiries and reduce network loading, allowing for targeted data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data acquisition is performed from all mobile devices in the network, then comprehensive data coverage is achieved, but network overload and transmission errors increase
Solution Approach 1:
The patent applies partial action by selectively acquiring data only from mobile devices that meet specific connection status criteria rather than attempting to acquire data from all devices. The system identifies and selects a subset of devices with suitable connection conditions (signal strength, spectral efficiency, handover status) to participate in data acquisition, thereby achieving sufficient data coverage while preventing network overload and transmission errors that would result from including all devices.
Solution Approach 2:
The patent implements feedback by continuously monitoring connection status parameters (signal strength, spectral efficiency, handover status) of mobile devices and using this information to dynamically adjust which devices are selected for data acquisition. The system evaluates current network conditions and device states, then makes real-time decisions about data acquisition eligibility, ensuring that only devices with adequate connection quality are included, thus maintaining transmission reliability.
2Measurement precision
If individual mobile devices are interrogated for connection status, then accurate selection is achieved, but network loading increases
Solution Approach 1:
The patent merges the connection status interrogation process into the existing data acquisition workflow. Instead of performing separate individual inquiries for each mobile device, the system combines the connection status evaluation with the data acquisition decision-making process. The network management unit retrieves connection status information as part of the overall data acquisition procedure, thereby achieving accurate device selection while minimizing additional network traffic.
Solution Approach 2:
The patent introduces an intermediary approach by having the network management unit centrally coordinate the connection status evaluation and data acquisition selection process. Rather than direct peer-to-peer interrogation between devices and acquisition targets, the network management unit acts as an intermediary that collects necessary connection information and makes centralized selection decisions, reducing the number of individual communication exchanges required.
3Adaptability or versatility
If resources are reserved based on current demand and position, then resource allocation flexibility is maintained, but network efficiency decreases due to erroneous transmissions
Solution Approach 1:
The patent changes the parameters used for resource allocation from basic demand and position information to include comprehensive connection status parameters such as signal strength, spectral efficiency, and handover status. By incorporating these additional parameters into the resource reservation decision-making process, the system maintains flexibility in allocating resources to appropriate devices while significantly improving network efficiency by preventing erroneous transmissions that would occur with devices having poor connection conditions.
