Abstract: The present disclosure relates to terminal devices, access network devices, air interface configuration methods, and wireless communications systems. In one example method, a second access network device in a radio access network determines air interface configuration information of an air interface between a terminal device and the radio access network, and sends a first air interface configuration message comprising the air interface configuration information to a first access network device in the radio access network. The first access network device and the second access network device use different wireless communications standards.

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: A configuration method is provided in a communications system. The communications system includes a master node and a secondary node that jointly provide a service for a terminal. The method includes: 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; and 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, thereby improving efficiency in radio resource management on the secondary node.
