摘要： The disclosure provides a method for assisting an unregistered user device to access private network services and a communication system. The method includes steps as follows. A request to access a private service of a private network is sent by a user device. In response to determining that the user device not registered on the private network wants to access the private service, the user device is assisted to obtain a temporary user profile by a mobile edge computing server through an emergency type attachment procedure. In response to determining that the user device is registered on the private network through the emergency type attachment procedure, a regular attachment procedure is executed by the user device based on the temporary user profile. In response to determining that the user device executes the regular attachment procedure, the mobile edge computing server provides the user device with the private service.

摘要： 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.

摘要： The disclosure provides a method for assisting an unregistered user device to access an end-to-end call service of a private network and a communication system. The method includes: determining whether the user device that is not registered on the private network wants to initiate a request of an emergency call; in response to determining that the user device that is not registered on the private network wants to initiate the request of the emergency call, assisting the user device to access the end-to-end call service without being registered on the private network.

摘要： The disclosure provides a base station and a method for optimizing the coverage of a self-defined network. The method includes: receiving a measurement report from user equipment; in response to determining that the measurement report indicates that a neighboring first base station is present, sending a member tracking message to the first base station; determining whether the first base station belongs to any other base station group based on a member tracking response from the first base station; in response to determining that the first base station does not belong to any other base station group, adding the first base station to a base station group managed by the base station; and in response to determining that the member tracking response indicates that the first base station belongs to another base station group, merging the base station group and the another base station group.
