An example method includes: receiving an uplink data packet sent by UE; if a signaling message is carried in the uplink data packet, separating the signaling message from the uplink data packet, where the signaling message is used to request to establish a PDU session or request to activate an established PDU session; forwarding the signaling message to a control plane device; and before an available PDU session exists, forwarding, based on a data forwarding message carried in the uplink data packet sent by the UE, data in the uplink data packet sent by the UE.

Data sending method and apparatus, and device

Embodiments of the present disclosure provide a method. According to the method, a mark is added to a data packet. After user equipment is handed over from an original device to a target device, and before a user plane network element receives a handover notification, the user plane network element sends, through a path used before handover, a data packet that carries a first mark to the original device. The original device modifies the first mark in the data packet to a second mark, and then forwards, to the target device, a data packet whose mark is modified and that carries the second mark. After receiving the handover notification, the user plane network element sends, to the target device, a data packet that carries a fourth mark. The target device can distinguish between sources of the received data packets based on different marks in the received data packets.
