1. A delay measurement method, comprising:
receiving, by a network device, first information from a core network, the first information including a request for the network device to measure a transmission delay between the network device and a terminal device;
determining, by the network device, the transmission delay between the network device and the terminal device following receipt of the first information using a protocol data unit (PDU) corresponding to a quality of service flow;
constraining the effective time of the transmission delay determination result based on a first preset duration; and
sending, by the network device, second information to the core network within the first preset duration, the second information indicating the determined transmission delay.
