LATENCY MEASUREMENT METHOD AND COMMUNICATION APPARATUS

Abstract

A latency measurement method and a communication apparatus is provided. A core network device can collect time information of a first packet in a first protocol data unit PDU set at a transmit end and time information of a last packet at a receive end, and determine a transmission latency (for example, an air interface downlink latency, an air interface uplink latency, a downlink latency at an interface between an access network device and the core network device, and an uplink latency at the interface between the access network device and the core network device) of the first PDU set between the transmit end and the receive end based on the time information of the first packet at the transmit end and the time information of the last packet at the receive end.
