Abstract: The present disclosure relates to the communications field, and discloses a data flow transmission method, a device, and a system, so as to resolve a problem of resource waste caused when a relay user equipment provides a relay service for a remote user equipment. A specific solution is as follows: A first network device triggers a first relay user equipment to establish a common data flow bearer with a second network device, and the first network device sends an identifier of a common data flow to a remote user equipment in a first group before or after the first network device triggers the first relay user equipment to establish the common data flow bearer with the second network device. The present disclosure is applied to data flow transmission.

Abstract: Embodiments of the present invention relate to the communications field and provide a bearer setup method, apparatus, and system. The method includes: receiving, by an MME, indication information, where the indication information is used to indicate a bearer type that is set up for UE; and setting up, by the MME, a bearer for the UE according to the indication information. By means of the method, indication information used to indicate a bearer type that is set up for UE is received, and different types of bearers are set up for the UE according to the indication information, so that an MME can adjust the bearer type in real time as required and set up different types of bearers for the UE, thereby efficiently transmitting sharply fluctuated data, and lowering loss of a network and the user equipment while improving user experience.

Abstract: A data transmission method provided in embodiments of the present application includes: determining, by a mobility management entity MME, that user equipment UE changes from an unreachable state to a reachable state; sending, by the MME, a request message to a serving gateway SGW; receiving, by the MME, downlink data sent by the SGW; and sending, by the MME, the downlink data to the UE. In this way, when the UE changes to a reachable state for downlink data, the MME requests the SGW to send the downlink data, and the MME then sends the downlink data to the UE, thereby avoiding loss of the downlink data caused by delivery of the downlink data to the UE that is in an unreachable state, and improving real-time accuracy of transmission.
