Claim 0:
1. A configuration method, applied to a communications system, wherein the communications system comprises a master node and a secondary node that jointly provide a service for a terminal, and the configuration method comprises:
generating, by the secondary node, configuration information for a signaling radio bearer (SRB), wherein the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal;
sending, by the secondary node, the configuration information for the SRB to the master node;
receiving, by the master node, the configuration information for the SRB from the secondary node;
sending, by the master node, the configuration information for the SRB to the terminal;
receiving, by the master node, 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 the master node, the first response message indicating that the SRB is successfully established by using the configuration information for the SRB;
sending, by the master node, the first response message to the secondary node; and
after the SRB is established,
sending, by the secondary node, a downlink RRC message of the secondary node on a first path to the terminal; and
receiving, by the secondary node, 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.
