According to one aspect of the present disclosure, a method for allowing slice consumers within or attached to the client device to access and use Network Slice Selection Assistance Information (NSSAI) comprises, at a client device: receiving, at an Application Programming Interface (API) layer within the client device, a query for NSSAI, the query being sent by a slice consumer; sending, to a Fifth Generation modem within the client device, the query for NSSAI; receiving, from the 5G modem, a response to the query for NSSAI; and sending, to the slice consumer, the response to the query for NSSAI. Enhancements to the N1 interface as well to Core Access and Mobility Management Function (AMF), Application Function (AF), and Network Exposure Function (NEF) are presented.
