数据包传输方法及相关设备
By sending and detecting bidirectional latency requests and timeout messages among network elements working collaboratively in the network, policy-based charging control rules are generated. This solves the problem that the bidirectional latency on the UPF side cannot meet the requirements of service flow, achieves stable transmission of the target service flow, avoids congestion and lag, and improves network transmission quality.

AI Technical Summary
Changes in network transmission quality can cause bidirectional latency on the UPF side to fail to meet the requirements of service flow, resulting in congestion and stuttering during data packet transmission. This can cause unusable issues, especially in AR and VR services.
By sending bidirectional latency requests to the policy control function network element through the application function network element, policy charging control rules and service quality detection policies that meet the bidirectional latency threshold values of the user plane function side are generated. Through the collaborative work of the session management function network element and the user plane function network element, latency timeout messages are detected and reported. The policy control function network element determines the target processing method to meet the latency requirements.
This ensures that the target service flow does not experience congestion or lag during network transmission, improves network transmission quality, and meets the high data rate and low latency requirements of services such as AR and VR.
