Abstract: Embodiments of this patent application provide a data transmission method and an apparatus for determining, by a core network (CN) device, a length of a quality of service flow identifier (QFI) used when a protocol data unit (PDU) session is established or modified for a terminal device; and sending, by the CN device, a first message to a radio access network (RAN) device, where the first message includes length information of at least one QFI. After receiving the first message from the core network CN device, the access network RAN sends a second message to the terminal device, where the second message includes the length information of the at least one QFI.

Abstract: This application provides a quality of experience measurement method and apparatus. A terminal device reports, to a network side, quality of experience measurement configuration related information corresponding to a first user identity or a second user identity that has been configured or negotiated in advance, or specifies that application layer measurement corresponding to different user identities are independent of each other in an upper layer of an access stratum of the terminal device, or when application layer measurement corresponding to the first user identity is interrupted or terminated due to impact of a service corresponding to the second user identity, the terminal device reports the interruption or termination to the network side.

Abstract: This application relates to the communications field, and in particular, to a data transmission method, an apparatus, and a system. In the data transmission method, a base station determines a transmission policy, where the transmission policy is used for contention-based uplink data transmission or non-contention based uplink data transmission; and sends the transmission policy to a terminal. The terminal receives the transmission policy sent by the base station, and sends uplink data to the base station based on the transmission policy. With a solution in this application, the base station can determine an appropriate transmission policy based on a network status, and send the transmission policy to the terminal, and the terminal can use, based on the transmission policy, an appropriate transmission mode to send uplink data to the base station, so that transmission efficiency is improved.
