Air Interface Resource Allocation for End-to-End Transmission Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for allocating air interface resources in wireless communication systems, such as LTE, only guarantee downlink service data transmission on the air interface, failing to ensure end-to-end transmission quality between a service server and user equipment.
Innovation Solution
A method and device where an access network device receives a service state report from user equipment to allocate air interface resources, ensuring end-to-end transmission quality by adjusting resource allocation based on service state parameters like video quality, packet loss ratio, and transmission delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air interface resources are allocated based on downlink QoS parameters only, then downlink transmission is guaranteed, but end-to-end transmission quality cannot be ensured
Solution Approach 1:
The patent implements feedback mechanisms where user equipment reports service state information (uplink QoS parameters) to the access network device. The access network device uses this feedback to dynamically adjust resource allocation, ensuring end-to-end transmission quality by coordinating both downlink and uplink QoS parameters rather than relying solely on downlink parameters.
2Productivity
If dynamic resource allocation is implemented, then transmission efficiency improves, but transmission quality guarantee deteriorates
Solution Approach 1:
The patent employs dynamic resource allocation where the access network device adjusts air interface resources based on real-time service state reports from user equipment. The allocation adapts to changing transmission conditions while maintaining quality guarantees through coordinated QoS parameter management, achieving both efficiency and reliability.
Solution Approach 2:
The system dynamically changes QoS parameters (such as packet loss ratio, transmission delay, bit rate) based on service state feedback. By adjusting these parameters in response to actual transmission conditions, the system maintains transmission quality guarantees while optimizing efficiency under varying network conditions.
