Abstract: Example configuration methods and apparatus are described with reference to an example communications system. The example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes that the secondary node generates configuration information for a signaling radio bearer (SRB), where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.

Abstract: A second access network node sends endpoint information of a second transmission path on the second access network node side to the first access network node. The second transmission path is a transmission path that is between the second access network node and a third access network node. The third access network node sends endpoint information of the second transmission path on the third access network node side to the first access network node. The first access network node sends the endpoint information of the second transmission path on the third access network node side to the second access network node, and sends the endpoint information of the second transmission path on the second access network node side to the third access network node.

Abstract: Example communication methods and apparatus are described. One example method includes that a first communications apparatus sends quality of service (QoS) flow information to a second communications apparatus, where a QoS flow indicated by the QoS flow information corresponds to at least one bearer type. The first communications apparatus receives a QoS flow list sent by the second communications apparatus based on the QoS flow information, where each QoS flow list is mapped to a radio bearer. The first communications apparatus sends a radio bearer identifier of the QoS flow list to the second communications apparatus. In the embodiments of this application, a base station itself determines a radio bearer or a DRB used to transmit the QoS flow.

Abstract: Example transmission rate control methods and apparatus are described. One example method includes obtaining a user equipment aggregate maximum bit rate (UE-AMBR) by a master base station. The master base station determines, based on the UE-AMBR, a first UE-AMBR used for the master base station and a second UE-AMBR used for a secondary base station. The master base station sends the second UE-AMBR to the secondary base station, and sends instruction information used to instruct the secondary base station to control data splitting for the master base station to the secondary base station. In this application, a transmission rate between each base station and a UE is controlled by allocating a UE-AMBR.
