Classification: CPC H | IPC H

Claim 13:
14. 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) from a secondary node, wherein the SRB is used to transmit a radio resource control (RRC) message between the secondary node and a terminal;
send the configuration information for the SRB to the terminal;
receive a first response message from the terminal, wherein the first response message is comprised in an RRC connection reconfiguration response message sent from the terminal to a master node, the first response message indicating that the SRB is successfully established by using the configuration information for the SRB;
send the first response message to the secondary node; and
after the SRB is established,
send a downlink RRC message of the secondary node on a first path to the terminal; and
send an uplink RRC message on a second path received from the terminal to the secondary node, 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 sent to the terminal by 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 sent to the terminal by the secondary node directly, the second path is that the uplink RRC message is sent to the secondary node directly.
