Abstract: The network service system includes a transmission controller and an authentication server. The transmission controller determines whether a service request belongs to a service of a proprietary network registered with the mobile edge computing platform and comprises an authentication request. The service request is from an electronic device. When the transmission controller determines that the service request belongs to a service of the proprietary network and comprises an authentication request, the authentication server executes an authentication mechanism according to packet information that corresponds to the service request, and the authentication mechanism triggers a permission server to confirm the identity information and permission information of the electronic device.

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 user equipment (UE) context migration management method applied to a mobile edge platform for managing a UE context of a mobile communication device is provided. An embodiment of the UE context migration management method includes: receiving at least one migration request for the UE context; calculating a first difference data corresponding to the UE context in response to the at least one migration request, wherein the first difference data represents a difference between the UE contexts obtained in two consecutive UE context retrieving operations corresponding to the at least one migration request; and transmitting the first difference data to the neighboring mobile edge platform to request the neighboring mobile edge platform to perform a migration operation of the UE context based on the first difference data.

Abstract: A gateway, system and method for multiple radio access technology service are provided. The gateway is between base stations and a core network, including a receiving module, determining module and processing module. The receiving module receives a packet from the base stations or the core network through a tunnel between the base stations and the core network. The determining module determines whether the packet has a virtual IP header. If the packet has a virtual IP header, the processing module deletes the virtual IP header and replaces it with a tunnel header to transmit the packet to the core network through the tunnel by the tunnel header. If the packet has no virtual IP header, the processing module forwards the packet to the core network through the tunnel. The disclosure enhances transmitting and processing performance of the packet when the packet is transmitted through only a single tunnel.
