Abstract: The present invention 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 invention is applied to data flow transmission.

Abstract: Embodiments of the present application provide a method for a handover without a default bearer. A first network device sends a relocation request to a second network device. The second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane. Then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command. Alternatively, after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device.

Abstract: A method of bearer deletion is provided to improve the universality of the bearer deletion process. The method includes: receiving, by the original intermediate NE, the cancellation type indication parameter sent by the HSS, and deleting the bearer between the serving gateway (S-GW) and a packet data network gateway (P-GW), if the original intermediate network element obtains an attach type according to the cancellation type indication parameter indicating an attach type and a corresponding bearer exists on the original intermediate NE. This method helps efficiently improve the universality of the bearer deletion flow.

Abstract: A method and an apparatus for displaying a network name are provided. A first mobility management device in a first network acquires first network name information, where the first network name information is a network name currently displayed on a user equipment UE, and/or a public land mobile network identity PLMN ID corresponding to the network name that is currently displayed on the UE, and the first network is a network with which the UE currently registers or a network of two networks with which the UE currently jointly register. If the UE switches over to a second network during a process of executing a service, the first mobility management device sends the first network name information to a second mobility management device in the second network, so that the second mobility management device sends, to the UE for displaying, a network name corresponding to the first network name information.
