Title:
LATENCY CONTROL METHOD, APPLICATION SERVER, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/174198
Kind Code:
A1
Abstract:
A latency control method, an application server, and a communication system. In the method, an application server receives an uplink data packet from a terminal device, wherein the uplink data packet comprises information of a timestamp, and the timestamp represents a generation time of the uplink data packet; the application server generates a downlink data packet according to the uplink data packet, wherein the downlink data packet comprises the information of the timestamp; and the application server sends the downlink data packet to a user plane function network element UPF, so that the UPF forwards the downlink data packet to the terminal device. In the method, when generating the downlink data packet, the application server carries the timestamp in the corresponding uplink data packet in the generated downlink data packet, so that when the downlink data packet is subsequently sent to a terminal by means of a device in a mobile communication system, the device in the mobile communication system can schedule the downlink data packet according to the information of the timestamp so as to ensure motion-to-photon (MTP) latency.
