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: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

Abstract: A method for a handover of a mobile station performed by a source base station and a target base station. The target base station receives a handover request message, from the source base station, in which includes QoS information of the mobile device, radio bearer identifier information of the source base station, and a first mapping relationship between a flow and a radio bearer of the source base station, the target base station acknowledges with a handover acknowledgement message. Therefore resource preparation at the target base station during a handover procedure is improved.

Abstract: Embodiments of this application provide a communication method, apparatus, a terminal, a network device, and a storage medium. After the terminal receives, from the network device, indication information used to indicate the terminal to report traffic pattern information of a first logical channel, a first PDU session, a first application, a first radio bearer, or a first QoS flow, the terminal reports the traffic pattern information of the first logical channel, the first PDU session, the first application, the first radio bearer, or the first QoS flow based on the indication information. In this manner, the terminal reports, based on the indication, the traffic pattern information of only the logical channel, the PDU session, the service, the radio bearer, or the QoS flow that is indicated by the network device.

Abstract: A data transmission method, a device, and a communications system are described. The method includes generating, by a terminal device, first indication information. The first indication information is used to indicate logical channel groups having to-be-sent data and amount of to-be-sent data on part of the logical channel groups having to-be-sent data. The method includes sending, by the terminal device, the first indication information. According to the data transmission method, the device, and the communications system provided in the described embodiments, when a current quantity idle bits in a MAC PDU is insufficient, the terminal device may indicate, to a network device by using the first indication information, the LCGs having to-be-sent data on the terminal device. In this way, uplink transmission resource allocation improved efficiency.
