Abstract: This application provides a method and an apparatus for determining an air interface latency and relates to the field of communications technologies. In the method, an access network device obtains an air interface latency of a downlink data packet and schedules the downlink data packet based on the air interface latency of the downlink data packet. The air interface latency of the downlink data packet is calculated based on a round-trip latency, and the round-trip latency is a latency from when a terminal sends an uplink data packet to when the terminal receives the downlink data packet corresponding to the uplink data packet. In the method, the access network device may schedule the downlink data packet based on the air interface latency of the downlink data packet, so as to precisely control a latency in uplink and downlink data transmission.

Abstract: A multicast communication method and a communication apparatus provide for transmission of data of a multicast service using a PDU session established by a terminal device to improve network element utilization. An AF network element sends first multicast service indication information to a session management network element indicating a first multicast service. The session management network element sends, based on the first multicast service indication information, multicast service information to an access network device that serves a terminal device. The access network device establishes an association relationship between the terminal device and the first multicast service based on the multicast service information, so that the access network device can send, when receiving data of the first multicast service, the data of the first multicast service to the terminal device using a PDU session.
