Abstract: A device authentication method and an apparatus are provided, to solve the problem of how to perform an authentication for the device in a UUDN. The method includes: obtaining, by a target access point (AP), a first timestamp sent by a local service center (LSC) device and a second timestamp sent by a terminal, where the second timestamp is sent by the LSC device to the terminal, and the first timestamp and the second timestamp are sent by the LSC device based on an AP switching event; when the first timestamp is consistent with the second timestamp, determining, by the target AP, that the terminal is an access terminal of the target AP.

Abstract: Provided are a protocol data unit (PDU) session management method and apparatus. The method includes: receiving an SM policy modification request for a PDU session, and the request triggering establishment of a first QoS flow in the PDU session, in which the PDU session is established by a first terminal; in response to data transmission tunnel having a same identifier as a flow identifier of the first QoS flow existing between a first UPF of a first satellite and a second UPF of a second satellite, establishing a first data transmission tunnel between the first UPF and the second UPF; and instructing the first UPF to transmit data of the first QoS flow through the first data transmission tunnel.

Abstract: A communication method, a device, an apparatus and a readable storage medium are provided. The communication method includes: receiving first information transmitted by a first UE; and when determining that the first UE supports a T2T service, processing the first information as follows: when the first information needs to be processed through a control plane, transmitting the first information to a second UE through a control plane channel; and when the first information needs to be processed through a data plane, transmitting the first information to the second UE through an inter-satellite channel.
