MTC Traffic Control via Conditional Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of machine-type communications (MTC) devices in wireless communications systems leads to potential network congestion due to uncontrolled transmissions, overwhelming the radio interface and network infrastructure.
Innovation Solution
Implementing a system and method for content-based traffic control, where MTC devices transmit information only when specific reporting conditions are met, prioritizing and sampling data to manage uplink transmissions efficiently, and allocating resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If MTC devices transmit data freely without constraints, then device communication functionality is maintained, but network congestion and traffic overload occur
Solution Approach 1:
The patent changes the transmission parameter from unconditional to conditional by introducing reporting conditions that must be satisfied before transmission occurs. This parameter change controls traffic volume while maintaining communication functionality when needed.
Solution Approach 2:
The system implements feedback mechanisms where devices evaluate their data against reporting conditions and only transmit when conditions are met. This feedback loop prevents unnecessary transmissions and manages network traffic effectively.
2Loss of information
If all MTC devices transmit data simultaneously, then complete information collection is achieved, but radio interface and network infrastructure are overwhelmed
Solution Approach 1:
Instead of requiring all devices to transmit all data, the patent applies partial action by allowing only devices with data meeting specific reporting conditions to transmit. This selective approach maintains information quality while preventing network overload.
Solution Approach 2:
The patent segments the transmission process by dividing devices into groups based on their data characteristics and reporting conditions. This segmentation allows controlled transmission from different device groups, preventing simultaneous overwhelming transmissions.
3Quantity of substance
If transmission constraints are imposed on MTC devices, then network congestion is reduced, but transmission delay increases
Solution Approach 1:
The patent introduces dynamic elements by allowing devices to transition between different transmission states based on their data characteristics and network conditions. This dynamic approach optimizes the balance between traffic control and transmission timing.
4Quantity of substance
If content-based reporting conditions are implemented, then unnecessary transmissions are reduced, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring reporting conditions and criteria in devices before actual data generation. This preliminary setup simplifies the decision-making process during operation, reducing real-time processing complexity while maintaining transmission efficiency.

AI summary
A method for operating a wireless device configured for wireless communications includes receiving a reporting request including a reporting condition that information stored at the device is required to satisfy in order for the device to transmit the information, and initiating an uplink transmission procedure to transmit the information when the reporting condition is satisfied.
