Abstract: A method for managing connections associated with multiple subscriber numbers is provided. The method includes the following steps: using a first subscriber number and a second subscriber number to establish two data connections with two mobile communication networks; receiving a QoS update notification from one of the wireless transceivers in response to the first data connection being used for data transfer of an application; and enabling the data transfer of the application to switch from the first data connection to the second data connection in response to the QoS update notification indicating that the QoS of the first data connection fails to support the application and the QoS of the second data connection is capable of supporting the application. Advantageously, the performance requirement of the application may be maintained after switching to the second data connection, thereby ensuring smooth operation of the application.

Abstract: A mobile communication device including a wireless transceiver, a storage device, and a controller is provided. The wireless transceiver performs wireless transmission and reception using a Radio Access Technology (RAT). The storage device stores program code of a management program. The controller loads and executes the management program in an application framework layer to perform management of network slicing configuration, including: inquiring of the wireless transceiver about first network slicing configuration that is currently applied in the wireless transceiver; in response to an application being activated, determining whether the first network slicing configuration meets one or more requirement parameters of the application; and in response to the first network slicing configuration meeting the requirement parameters of the application, sending a first configuration success message to the application without requesting the wireless transceiver to reconfigure the first network slicing configuration.
