Solution Overview
Problem
Existing solutions for managing Wi-Fi hotspots fail to accurately identify and control abnormal traffic usage, leading to economic losses for hotspot enablers, as they rely on terminal-side parameter settings that are ineffective in preventing excessive data consumption.
Innovation Solution
A traffic processing method and apparatus that involves a user plane function network element receiving hotspot indication information, obtaining characteristic parameters of data packets, and determining abnormal traffic, sending notifications, and buffering or discarding packets to manage traffic effectively without relying on user-end settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal-side parameter settings are used to control Wi-Fi hotspot traffic, then ease of operation is improved, but measurement precision of abnormal traffic is worsened
Solution Approach 1:
The patent introduces a network element as an intermediary between the terminal device and the traffic management system. This network element receives traffic data from the terminal, performs precise abnormal traffic identification using multiple criteria (traffic type, data volume, time duration), and sends control instructions back to the terminal. This intermediary approach allows the terminal to operate with simple parameters while the network element performs complex precise measurements and decision-making.
2Device complexity
If terminal-side parameter settings are used to control Wi-Fi hotspot traffic, then device complexity is reduced, but reliability of traffic control is worsened
Solution Approach 1:
The patent implements a feedback mechanism where the network element continuously monitors traffic data from the terminal device, compares it against predefined thresholds and criteria, and sends control instructions back to the terminal when abnormal traffic is detected. This closed-loop feedback system ensures reliable traffic control without requiring complex local decision-making at the terminal, maintaining low device complexity while achieving high reliability through network-based monitoring and control.
3Measurement precision
If network-based traffic monitoring is implemented, then measurement precision of abnormal traffic is improved, but device complexity of the network system is worsened
Solution Approach 1:
The patent segments the traffic management functionality into distinct components: the terminal device handles simple traffic generation and basic parameter storage, while the network element handles complex traffic analysis, abnormal traffic identification, and control decision-making. This segmentation allows precise traffic measurement to be performed at the network level without requiring the entire system to be complex, as each component focuses on its specific function with appropriate complexity level.
