1. A method performed by a wireless device, the method comprising:
performing, over a first cell associated with a public network, a non-access stratum (NAS) procedure in which the wireless device is authenticated as being authorized to access a non-public network;
transmitting, via the first cell, secured NAS signaling which indicates one or more identifiers associated with the non-public network that the wireless device targets to access, wherein either:
the non-public network is a standalone non-public network (SNPN), and the one or more identifiers include a public land mobile network identity (PLMN ID) and a network identifier (NID); or
the non-public network is a public network integrated non-public network (PNINPN), and the one or more identifiers include a public land mobile network identity (PLMN ID); and
after performing the NAS procedure, receiving from the first cell a mobility command that commands the wireless device to perform a mobility procedure towards a second cell associated with the non-public network, wherein the mobility command is received responsive to transmitting the secured NAS signaling.
