Claim 9:
10. An apparatus, applied for a first access network device, comprising:
at least one processor and a memory storing instructions for execution by the at least one processor;
wherein, when executed, the instructions cause the apparatus to perform operations comprising:
receive, by a packet data convergence protocol (PDCP) layer of a first access network device, a data unit comprising master cell group (MCG) link failure information from a terminal device via a secondary cell group (SCG) of a second access network device;
process, 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
deliver, 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.
