Abstract: A network device requests, from a mobile network, a check of network slicing eligibility for a first session involving a first user, a first application, and a first application server. The network device receives, based on the check of network slicing eligibility, network slicing plan information associated with the first user and network slicing configuration information of the mobile network. The network device identifies a network slice identifier (ID) of a first network slice of the mobile network based on an identity of the first application, the network slicing plan information, and the network slicing configuration information; and sends a notification message, that includes the network slice ID, to the first application server for notifying the first application of the first network slice to use for the first session.
