Abstract
A method performed by a wireless device (12). The method comprises performing, over a first cell (14) associated with a public network, a non-access stratum (NAS) procedure in which the wireless device (12) is authenticated as being authorized to access a non-public network. The method also comprises after performing the NAS procedure, receiving from the first cell (14) a mobility command that commands the wireless device (12) to perform a mobility procedure towards a second cell (16) associated with the non-public network.
Claims19
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.
A method performed by a radio network node configured to serve a first cell associated with a public network, the method comprising:
- receiving, from a core network node, control signaling which indicates a non-public network that a wireless device is authorized to access, targets to access, and/or is to be moved to, wherein either:
- the non-public network is a standalone non-public network (SNPN), and the control signaling indicates the non-public network by indicating a public land mobile network identity (PLMN ID) and a network identifier (NID) associated with the non-public network;
- or
- the non-public network is a public network integrated non-public network PNINPN), and the control signaling indicates the non-public network by indicating a closed access group (CAG) identifier, or a network slice identifier, associated with the non-public network;
- determining a second cell associated with the non-public network;
- and
- transmitting, to the wireless device, a mobility command that commands the wireless device to perform a mobility procedure towards the second cell.
A method performed by a core network node, the method comprising:
- authenticating a wireless device as being authorized to access a non-public network;
- and
- transmitting, from the core network node to a radio network node configured to serve a first cell associated with a public network, control signaling which indicates the non-public network that the wireless device is authorized to access, targets to access, and/or is to be moved to.
A method performed by a radio network node configured to serve a first cell associated with a public network, the method comprising:
- receiving, from a core network node, control signaling which indicates a non-public network that a wireless device is authorized to access, targets to access, and/or is to be moved to;
- determining a second cell associated with the non-public network, wherein the second cell conceals from the wireless device an association of the second cell with the non-public network, and wherein the first cell advertises to the wireless device that the first cell is associated with the public network;
- and
- transmitting, to the wireless device, a mobility command that commands the wireless device to perform a mobility procedure towards the second cell.
