Single-Purpose Identifier for IoT Data Transmission Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as those in 5G networks, face inefficiencies due to simultaneous data transmission from multiple IoT devices reporting the same information, leading to resource overload and delayed message delivery, as existing solutions like access class barring and eSIM identifiers fail to effectively manage these scenarios.
Innovation Solution
Implementing a Single-Purpose Identifier (SP-ID) that maps semantic meaning to specific identifiers, allowing base stations to grant transmission requests only for a subset of devices serving the same purpose within a defined time window, thereby optimizing resource allocation and reducing unnecessary data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple IoT devices transmit data simultaneously to report the same information, then the system can ensure comprehensive data collection, but it causes resource overload and delayed message delivery
Solution Approach 1:
The patent applies partial action by selecting only a subset of IoT devices to transmit data when multiple devices have the same data to report. The base station identifies duplicate data from multiple sources and grants transmission permission to only one or a limited number of devices, rather than allowing all devices to transmit simultaneously. This reduces network congestion and delivery delay while still ensuring the complete data is collected.
2Reliability
If all service requests are granted to ensure complete data transmission, then data collection is comprehensive, but system resources are wasted due to redundant transmissions
Solution Approach 1:
The patent merges multiple identical data transmissions into a single transmission by having the base station identify when multiple devices have the same data to report. When duplicates are detected, the base station combines these requests and grants permission to only one device to transmit the data, eliminating redundant energy consumption while maintaining complete data collection.
Solution Approach 2:
The patent changes the parameter of transmission permission from a binary grant/deny decision to a selective grant based on data uniqueness. The base station evaluates the data content parameter and adjusts transmission permissions accordingly, granting permission only for unique data and denying or combining permissions for duplicate data, thereby optimizing energy usage.
3Adaptability or versatility
If transmission permissions are granted to all devices, then every device can communicate its data, but congestion increases and network performance deteriorates
Solution Approach 1:
The patent implements feedback by having the base station monitor incoming service requests from multiple IoT devices, identify when multiple devices have identical data to report, and provide selective transmission permissions based on this analysis. The base station gives feedback to devices about whether their transmission request is granted or denied, optimizing network performance while preserving device communication capability.
