摘要： 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.

摘要： A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.

摘要： 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.
