RAN QoS Profile Selection for Terminal Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods are inadequate for complex communication scenarios, failing to account for varying network statuses and terminal loads, leading to inefficient data transmission and potential terminal overload.
Innovation Solution
A communication method and apparatus that enables a RAN node to actively modify quality of service profiles based on current network status and terminal load, using candidate profiles to determine an appropriate quality of service profile, thereby controlling terminal load and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed QoS profile mapping method is used, then the mapping process is simple, but it cannot adapt to complex communication scenarios with varying network status and terminal load
Solution Approach 1:
The patent transforms the fixed QoS profile mapping into a dynamic process where the RAN node actively selects from multiple candidate QoS profiles based on real-time network status and terminal load conditions. The mapping relationship between QoS flows and QoS profiles is no longer static but dynamically adjusted according to current system state, enabling adaptation to complex communication scenarios while maintaining manageable complexity through automated decision-making.
2Reliability
If the RAN node actively modifies QoS profiles based on terminal load, then terminal overload is prevented and user experience improves, but the control complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the RAN node continuously monitors terminal load and network status, then adjusts QoS profile selection accordingly. The system receives feedback about terminal conditions and automatically modifies QoS profile mapping to prevent overload. This closed-loop control ensures reliable terminal load management while the automated feedback process reduces the need for complex manual control configurations.
3Adaptability or versatility
If multiple candidate QoS profiles are considered, then the appropriate QoS profile can be determined for different scenarios, but the decision-making process becomes more complex
Solution Approach 1:
The RAN node performs self-service by automatically selecting the most appropriate QoS profile from multiple candidates based on its own monitoring of network status and terminal load conditions. The system uses its intrinsic capabilities to make autonomous decisions without requiring complex external control mechanisms or manual intervention, thereby achieving flexible scenario adaptation while keeping the decision-making process manageable through automated local intelligence.

AI summary
A communication method includes obtaining transmission mode indication information. The transmission mode indication information indicates to one or more of transmit first information to a terminal by using air interface signaling, or transmit the first information to a user plane function network element in a user plane manner. The communication method also includes sending the first information based on the transmission mode indication information. The first information is for determining a first parameter. The first parameter includes at least one of a task split point, a task amount for task processing, a bit rate, a data rate, a frame rate, or a resolution.
