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: 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.

Abstract: The present application provides a data transmission method in a wireless communication system. A first security parameter indication is introduced into uplink data on a first bearer, and a base station can determine, based on the first security parameter indication in the uplink data, whether first security processing of the uplink data is performed using a first security parameter or a second security parameter, so as to select a corresponding security parameter to perform second security processing; and a second security parameter indication is introduced into downlink data, and UE can determine, based on the second security parameter indication in the downlink data, whether the first security processing of the data is performed using the first security parameter or the second security parameter, so as to select a corresponding security parameter to perform the second security processing.
