Mobile communication devices and methods for managing network slicing configuration

A User Equipment (UE), comprising:

• a wireless transceiver, configured to perform wireless transmission and reception using a Radio Access Technology, RAT;
• a storage device, configured to store program code of a management program;
• and
• a controller, configured to load and execute the management program in an application framework layer to perform management of network slicing configuration, wherein the management of network slicing configuration comprises:
• 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 a plurality of requirement parameters of the application;
• 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;
• in response to the first network slicing configuration not meeting the requirement parameters of the application, requesting the wireless transceiver to reconfigure the first network slicing configuration to meet the requirement parameters of the application;
• and
• in response to the wireless transceiver completing the reconfiguration of the first network slicing configuration, sending a second configuration success message to the application.
