Core Network Resource Scheduling for Wireless Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video transmission systems in wireless communication do not effectively learn the transmission situation of reference frames, leading to wastage of air interface resources as terminal devices discard video frames when reference frames fail to transmit or decode, especially during network congestion.
Innovation Solution
A method where a core network device determines and transmits first information about data sets to an access network device, enabling it to assess the importance and association relationships of these data sets, thereby scheduling air interface resources based on this information to prioritize and manage resource allocation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video frames are transmitted without considering reference frame transmission status, then transmission simplicity is maintained, but air interface resources are wasted when reference frames fail to transmit
Solution Approach 1:
The core network device performs preliminary actions by determining the transmission status of reference frames before scheduling video frames. The access network device receives this information and uses it to pre-judge whether to allocate air interface resources for video frame transmission, avoiding waste when reference frames have failed to transmit successfully.
Solution Approach 2:
The system implements feedback mechanisms where the core network device provides feedback information about reference frame transmission status to the access network device. This feedback loop enables the access network device to adjust its scheduling decisions based on actual transmission outcomes, improving resource allocation efficiency.
2Reliability
If all video frames are transmitted equally, then scheduling simplicity is maintained, but transmission reliability decreases during network congestion
Solution Approach 1:
The system applies local quality differentiation by treating different video frames differently based on their importance and dependency relationships. The access network device schedules frames with higher importance (such as I-frames or key P-frames) with higher priority than less important frames, ensuring reliable transmission of critical video data during congestion.
Solution Approach 2:
The scheduling mechanism is dynamic, adjusting frame transmission priorities based on real-time network conditions and reference frame transmission status. During network congestion, the system dynamically prioritizes frames that are more likely to succeed, while during normal conditions it may adopt more aggressive transmission strategies.
3Loss of energy
If air interface resources are allocated without considering data set importance, then resource allocation simplicity is maintained, but resource waste increases
Solution Approach 1:
The system changes the parameter of resource allocation priority based on data set importance and association relationships. The core network device determines these parameters and transmits them to the access network device, which then adjusts air interface resource allocation accordingly, allocating more resources to important data sets and fewer resources to less important ones.
