Access Network Resource Allocation for Time-Sensitive Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in quickly adjusting transmission resources to meet the high-quality transmission requirements of terminal devices, particularly during applications like virtual reality or industrial IoT tasks, as the process of modifying protocol data unit (PDU) sessions is time-consuming and inefficient.
Innovation Solution
The terminal device sends access stratum (AS) layer request information to the network device to negotiate and adjust the quality of transmission resources, allowing for faster and more timely allocation of resources that meet the specific transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network uses the traditional PDU session modification process to adjust transmission resources, then the transmission quality can be improved, but the time delay increases and the response speed decreases
Solution Approach 1:
The patent segments the transmission resource adjustment process into two parts: urgent resource adjustments handled directly by the access network device without core network involvement, and non-urgent adjustments handled through the traditional PDU session modification process. This segmentation allows time-sensitive requests to be processed immediately, reducing time delay while maintaining transmission quality for non-urgent cases.
Solution Approach 2:
The patent introduces an access network device as an intermediary that can directly allocate transmission resources based on terminal device requests without requiring core network intervention. This intermediary role enables faster response to transmission quality requirements by handling resource allocation locally at the access network level.
2Reliability
If the network uses the PDU session modification process to change transmission resources, then the transmission quality requirements can be met, but the processing efficiency decreases
Solution Approach 1:
The patent enables the access network device to autonomously handle transmission resource allocation based on terminal device requests, without requiring core network processing. This self-service capability at the access network level significantly improves processing efficiency for time-sensitive transmission quality adjustments, while the core network retains control for non-urgent cases.
3Speed
If the network responds quickly to transmission resource requests, then the terminal device's temporary high-quality transmission needs are met, but the traditional protocol requires time-consuming PDU session modification
Solution Approach 1:
The patent implements a dynamic resource allocation mechanism where the access network device can quickly adjust transmission resources in response to terminal device requests. This dynamic approach allows the system to adapt to changing transmission quality requirements in real-time, improving response speed while maintaining the ability to use traditional PDU session modification for non-urgent adjustments.
