Abstract: A device and message management method for vehicle-to-everything (V2X) service applied to a mobile edge platform (MEP) for managing a mobile device and V2X messages thereof is provided. The MEP is connected to the mobile device through a first base station. The method includes: obtaining mobile device signal strength information and base station signal strength information from the first base station; determining current location of the mobile device based on the mobile device signal strength information; and generating a mobile device list corresponding to the first base station and a second base station neighboring to the first base station based on the determined current location of the mobile communication device and the base station signal strength information so as to perform a message broadcasting operation on the V2X messages of the mobile device between the first base station and the second base station using the mobile device list.

Abstract: A Multi-Access Edge Computing (MEC) system is provided. The MEC system includes a user equipment (UE), an MEC device, and a core network. The MEC device includes a relay User Plane Function (UPF) module, a first UPF module, and a second UPF module. The core network performs a UPF path management corresponding to the UE based on a notification of the MEC device. When the UE attaches to a network, the MEC device establishes an idle session between the UE and the relay UPF module. When the MEC device determines that a service for the UE needs to be switched from the first UPF module to the second UPF module and the second UPF module has not been activated, the MEC device notifies the core network to switch the service for the UE from the first UPF module to the relay UPF module first.

Abstract: A network service method includes the following steps. A multi-access edge computing cloud server receives a service request from a terminal device and records the internal Internet protocol address of the terminal device. And, the internal Internet protocol address transmitted from the terminal device or the multi-access edge computing cloud server is received by a core cloud server, and correspondence between the internal Internet protocol address and the external Internet protocol address of the terminal device is recorded by the core cloud server.
