Abstract
A communications method includes: an integrated access and backhaul (IAB) node receives an uplink data packet from a terminal; the IAB node determines a packet data convergence protocol (PDCP) layer security status of the uplink data packet; the IAB node determines a target secure tunnel from a plurality of secure tunnels between the IAB node and an IAB donor based on the PDCP layer security status of the uplink data packet; and the IAB node sends the uplink data packet to the IAB donor through the target secure tunnel. This application is applicable to a data transmission process.
