1. A communication method, comprising:
receiving, by a packet data convergence protocol (PDCP) layer of a first access network device from a terminal device via a secondary cell group (SCG) of a second access network device, a data unit comprising master cell group (MCG) link failure information;
processing, by the PDCP layer of the first access network device, the data unit, the processing comprising determining that the data unit includes the MCG link failure information; and
delivering, by the PDCP layer of the first access network device in response to the determination, the processed data unit to a radio resource control (RRC) layer of the first access network device without performing at least one of a reordering function or an in-order delivery function on the data unit.
