Abstract
Methods and apparatus are disclosed for controlling whether a user equipment (UE) is allowed to access a cell of a closed access group (CAG) when the CAG is selected manually by a user of the UE.
Claims3
A method performed for a base station in a Non-Public Network, the method comprising:
- operating at least one cell for at least one closed group;
- receiving, from a user equipment (UE) via a cell of the at least one cell, a message for registering the UE with a core network node for mobility management, wherein a closed group from the at least one closed group corresponding to the cell is manually selected by a user of the UE and is not included in an allowed closed group list;
- forwarding the message to the core network node;
- receiving, from the core network node, a response to the message for allowing the registering of the UE even though the closed group is not included in the allowed closed group list, wherein the allowed closed group list is updated;
- and
- configuring a connection with the UE for allowing the UE to communicate via a cell corresponding to another closed group included in the un-updated allowed closed group list to register the UE with the core network node, wherein the allowed closed group list includes information indicating at least one limitation for corresponding cells for the at least one closed group.

A base station in a Non-Public Network, the base station comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- operate at least one cell for at least one closed group;
- receive, from a user equipment (UE) via a cell of the at least one cell, a message for registering the UE with a core network node for mobility management, wherein a closed group from the at least one closed group corresponding to the cell is manually selected by a user of the UE and is not included in an allowed closed group list;
- forward the message to the core network node;
- receive, from the core network node, a response to the message for allowing the registering of the UE even though the closed group is not included in the allowed closed group list, wherein the allowed closed group list is updated;
- and
- configuring a connection with the UE for allowing the UE to communicate via a cell corresponding to another closed group included in the un-updated allowed closed group list to register the UE with the core network node,
- wherein the allowed closed group list includes information indicating at least one limitation for corresponding cells for the at least one closed group.

A method performed by a mobile device in a Non-Public Network, the method comprising:
- transmitting, to a base station via a cell corresponding to at least one closed group, a message for registering the mobile device with a core network node for mobility management, wherein a closed group from the at least one closed group corresponding to the cell is manually selected by a user of the mobile device and is not included in an allowed closed group list;
- configuring a connection with the base station for allowing the mobile device to communicate via a cell corresponding to another closed group included in the allowed closed group list to register the mobile device with the core network node, even though the closed group is not included in the allowed closed group list, wherein the allowed closed group list is not updated, wherein
- the allowed closed group list includes information indicating at least one limitation for corresponding cells for the at least one closed group.
