9. A network device comprising:
a processor configured to:
receive from an end device via a non-slice radio access device, a packet data network (PDN) connection request that includes network slice (NS) and access point name (APN) information, wherein the network device is an inter-networking network device of a core network, and wherein the NS and APN information includes a network slice identifier, an application identifier, and an APN;
provision, based on the NS and APN information, a PDN session via the non-slice radio access device of a PDN connection to an application server;
receive, during the PDN session, a modification to the PDN session pertaining to a slice-enabled radio access device to which the end device is attached; and
provision, based on the NS and APN information, a network slice, which includes the slice-enabled radio access device, and supports a packet data unit (PDU) session to the application server, wherein the NS and APN information identifies the network slice.
