Abstract: Embodiments of the present disclosure disclose a data packet transmission method and apparatus. The data packet transmission method includes: obtaining data type information and data packet identification information of a data packet; calculating the data type information and the data packet identification information by using a preset MAC algorithm, to obtain a first message authentication code; and sending the data packet that includes the data type information and the first message authentication code to a node device, so that the node device checks the data type information according to the first message authentication code. By means of the embodiments of the present disclosure, security identification may be performed on the data type information of the data packet, thereby improving transmission reliability of the data type information.

Abstract: Embodiments of the present disclosure provide a GTP-U downlink packet sending method and apparatus. The method includes: receiving, by a MEC platform, a GTP-U uplink packet sent by a base station device; obtaining, by the MEC platform, a TEID of the base station device according to the GTP-U uplink packet; and sending, by the MEC platform, a GTP-U downlink packet to the base station device, where the GTP-U downlink packet includes the TEID of the base station device. By using the technical solutions of the embodiments of the present disclosure, after receiving the GTP-U uplink packet sent by the base station device, the MEC platform can obtain the TEID of the base station device according to the GTP-U uplink packet, and therefore, can correctly perform GTP-U encapsulation, and send the GTP-U downlink packet to the base station device.
