Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data request processing methods in wireless communications networks are not adaptive to real-time changes in network conditions, leading to congestion when terminals request high-definition services without timely awareness of network congestion.
Innovation Solution
A method and apparatus that send a service quality request message to a PCRF to acquire a data request processing instruction based on the current network status, determining whether to adjust the bit rate or switch to a different network channel when network congestion is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal determines data parameters based on detected signal strength and requests high-definition video when signal is strong, then the user experience is improved, but network congestion occurs when the network enters a critical state without timely detection by the terminal
Solution Approach 1:
The network side establishes a feedback mechanism by sending service quality indication information to the terminal based on real-time network status. When the network enters a critical congestion state, the network side proactively notifies the terminal to adjust data parameters, enabling the terminal to adapt its data requests according to actual network conditions and avoid contributing to further congestion.
Solution Approach 2:
The network side performs preliminary assessment of network status and sends service quality indication information to the terminal before congestion fully develops. This allows the terminal to proactively adjust its data parameters in advance, preventing the terminal from requesting high-definition content that would exacerbate emerging congestion conditions.
2Productivity
If the network side provides data according to parameters determined by the terminal without real-time network status information, then the terminal's data request is fulfilled, but the method is not adaptive to frequent and sharp changes in wireless network environment
Solution Approach 1:
The network side implements real-time feedback by continuously monitoring network status and sending service quality indication information to the terminal. This feedback loop enables the terminal to dynamically adjust its data parameters according to current network conditions, making the system adaptive to frequent and sharp changes in the wireless network environment while maintaining efficient data transmission.
Solution Approach 2:
The system transitions from a static approach where the terminal determines parameters independently to a dynamic approach where the network side continuously provides service quality indications. This enables real-time adaptation to changing network conditions, allowing the terminal to flexibly adjust data parameters in response to dynamic network status changes.

AI summary
According to a method and apparatus for controlling data transmission in a wireless communications network, a service quality request message is sent to a PCRF when a data request message of a terminal is received; and the PCRF queries a current network status, so as to determine a processing instruction for a data request message of the terminal according to the current network status and the data request message, and process the data request message of the terminal according to the processing instruction. Therefore, processing on the data request message of the terminal not only depends on a parameter carried in the data request message of the terminal, but also uses the current network status as a constraint condition, so that a processing manner for the data request message can be adaptive to a real-time change of the wireless communications network.
