Classification: CPC H | IPC H

Claim 18:
19. An apparatus, the apparatus comprising at least one processor and one or more memories coupled to the at least one processor, the one or more memories storing instructions for execution by the at least one processor to:
receive configuration information for a signaling radio bearer (SRB) of a secondary node from a master node, wherein the SRB is used to directly transmit a radio resource control (RRC) message between the secondary node and the apparatus;
configure the SRB by using the configuration information for the SRB;
send a first response message to the secondary node via the master node, wherein the first response message is comprised in an RRC connection reconfiguration response message sent to the master node, the first response message indicating that the SRB is successfully established by using the configuration information for the SRB; and
after the SRB is successfully established,
receive a downlink RRC message of the secondary node on a first path; and
send an uplink RRC message to the secondary node on a second path, wherein the uplink RRC message is a response message for the downlink RRC message, and wherein:
when the first path is that the downlink RRC message is received by the apparatus from the secondary node via the master node, the second path is that the uplink RRC message is sent to the secondary node via the master node; and
when the first path is that the downlink RRC message is received by the apparatus from the secondary node directly, the second path is that the uplink RRC message is sent to the secondary node directly.
