Abstract: The present application relates to the field of wireless communication technology, in particular to a data transmission method and device, used to solve the problem of there being no solution for sending cached downlink data in a source communication system to a UE after the UE crosses the communication system. An MME entity in a second mobile communication system of an embodiment of the present application receives a downlink data cache indication sent by an SMF entity located in a first mobile communication system; the MME entity initiates the establishment of a user plane connection and/or control plane connection of a UE, so that a user plane functional entity sends the cached downlink data to the UE by means of the user plane connection and/or control plane connection. Since the UE of the embodiment of the present application sends the downlink data cached in the first mobile communication system to the UE by means of the user plane and/or control plane connection established by the second mobile communication system after moving to the second mobile communication system, loss of the cached downlink data of the UE is avoided, the system reliability is improved and the system performance is also improved.

Abstract: The present disclosure provides a first relay node discovery method and apparatus, and a storage medium. On a second relay node side, the method includes: receiving a first message, which carries an identifier of a target service; and broadcasting the first message. The first message is used to inform a second relay node to assist in discovering a first relay node capable of accessing the target service. Therefore, based on the second relay node, a remote terminal can discover the first relay node that is far away from the remote terminal through a multi-hop mode, which solves the problem that it is difficult for the remote terminal to discover the first relay node caused by the relatively long distance between the remote terminal and the first relay node.
