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: An SDN (Software Defined Networking) system with auto-deployment switches and a method for auto-deploying the switches in said SDN system are proposed. The method includes: actively sending a configuration message out by a controller, with said configuration message having an IP (Internet Protocol) address of the controller and a plurality of parameters; receiving the configuration message by a switch; and building a connection between the switch and the controller according to the IP address of the controller and the plurality of parameters.
