Claim 9:
10. An apparatus for a terminal, comprising at least one processor, wherein the at least one processor is coupled to a memory storing executable instructions that, when executed by the at least one processor, cause the terminal to perform operations comprising:
receiving first configuration information of a first bearer from a secondary node through a master node, wherein the first configuration information comprises configuration information for releasing and adding, by the terminal, a packet data convergence protocol (PDCP) entity of the first bearer terminated at the secondary node, wherein the first configuration information further comprises configuration information for releasing and adding a radio link control protocol layer (RLC) entity of the first bearer; and the configuration information for releasing and adding the RLC entity comprises configuration information for releasing the RLC entity corresponding to a bearer identifier of the first bearer and configuration information for adding the RLC entity corresponding to the bearer identifier; and
configuring the first bearer based on the first configuration information, wherein the terminal connects to both the master node and the secondary node; and wherein:
the configuration information for releasing and adding a PDCP entity comprises configuration information for releasing a PDCP entity and configuration information for adding a PDCP entity, and the configuration information for releasing a PDCP entity and the configuration information for adding a PDCP entity include a same bearer identifier; and wherein configuring the first bearer based on the first configuration information comprises:
releasing a PDCP entity of the first bearer, and adding a PDCP entity of the first bearer, based on the configuration information for releasing and adding a PDCP entity of the first bearer, wherein a PDCP sequence number (SN) length of the released PDCP entity is different from a PDCP SN length of the added PDCP entity.
