Classification: CPC H | IPC H

Claim 7:
8. 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:
generate configuration information for a signaling radio bearer (SRB) wherein the SRB is used to transmit a radio resource control (RRC) message between a secondary node and a terminal;
send the configuration information for the SRB to a master node, wherein the configuration information for the SRB is sent to the terminal through the master node;
receive by the secondary node, a first response message from the master node, wherein the first response message is comprised in an RRC connection reconfiguration response message sent from the terminal 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 established,
send a downlink RRC message of the secondary node on a first path to the terminal; and
receive an uplink RRC message on a second path from the terminal, 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 received by the secondary node via the master node; and
when the first path is that the downlink RRC message is sent to terminal by the secondary node directly, the second path is that the uplink RRC message is received by the secondary node directly.
