Abstract: This application provides a data transmission method. In the method, a first access network device and a second access network device establish a data radio bearer (DRB)-based tunnel and a session-based tunnel. The second access network device sends a Packet Data Convergence Protocol (PDCP) layer data packet to the first access network device via the DRB-based tunnel; and the second access network device sends a Service Data Adaptation Protocol (SDAP) layer data packet to the first access network device via the session-based tunnel.

Abstract: In the embodiments of the present invention, UE can complete, by using only two interaction steps instead of six steps in the prior art, a process of sending a data packet to an eNodeB. Even a random access process in the six steps in the prior art includes four interaction steps, and by contrast, in the embodiments, signaling that needs to be consumed on an eNodeB when the UE sends data can be significantly reduced. This is relatively suitable for a scenario in which small data or occasional data is sent.

Abstract: Embodiments of this application provide a duplication mode communication processing method in a central unit-distributed unit (CU-DU) architecture. In a possible implementation, in a process of establishing a user plane tunnel between a CU and a DU by exchanging information about uplink tunnel endpoints and information about downlink tunnel endpoints, the DU provides an identity of a primary path to the CU, thereby implementing a duplication mode of a data radio bearer.

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 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.
