Abstract

See full text

A communication device, network node and methods therein in for handling network slices in a wireless communication network are disclosed. The communication device encrypts Network Slice Selection Assistance information, NSSAI, using public key cryptography and includes the encrypted NSSAI in a Non Access Stratum, NAS, registration request. Then the communication device sends a Radio Resource Control, RRC, request to the network node including the NAS registration request. The network node receives the RRC connection request from the communication device and selects a network function based on information in the RRC connection request. The network node forwards the NAS registration request to the network function and forwards to the communication device a NAS registration response received from the network function after the network function decrypting the NSSAI using a PLMN private key.
