1. A secondary network device, comprising:
at least one processor; and
a non-transitory memory coupled to the at least one processor and configured to store executable instructions that are executable by the at least one processor, the executable instructions including instructions to:
receive an s-node addition request message or an s-node modification request message from a master network device, wherein the s-node addition request message or the s-node modification request message comprises configuration information, first indication information, and third indication information, the configuration information indicates that a first radio bearer (RB) is associated with M radio link control (RLC) entities of the secondary network device, M is 1, 2, or 3, a value of two bits comprised in the configuration information is M, the first indication information indicates whether there is a master RLC entity in the M RLC entities, the third indication information comprises identifiers of any secondary RLC entities and master RLC entity that are associated with the first RB in the master network device, and the first RB is associated with one master RLC entity and a maximum of three secondary RLC entities; and
send second indication information having a length of 3 bits to a terminal device, wherein the second indication information indicates a status of each secondary RLC entity associated with the first RB, and different secondary RLC entities associated with the first RB correspond to different bits in the 3 bits.
