Network node and user equipment that initiate a connection
A network node includes a receiver configured to receive, from a user equipment, a message requesting an initial registration or a location registration from a user equipment; and a transmitter configured to transmit a message to the user equipment when the user equipment is disallowed to connect to any one of one or more network slices, the message allowing the initial registration or the location registration including information related to a connection restriction that causes the user equipment to transition into a state in which the user equipment is registered and the user equipment is not allowed to use a service.
1. A network node comprising:
a receiver configured to receive, from a user equipment, a message requesting an initial registration or a location registration;
a transmitter configured to transmit a message to the user equipment when the user equipment is disallowed to connect to any one of one or more network slices, the message allowing the initial registration or the location registration including information related to a connection restriction that causes the user equipment to transition to a state in which the user equipment is registered and the user equipment is not allowed to use a service; and
a controller configured to determine whether the user equipment is connectable only to a Closed Access Group (CAG) cell,
wherein, when a result of the determination is that the user equipment is connectable only to the CAG cell and the user equipment is disallowed to connect to any one of the one or more network slices, the transmitter transmits, to the user equipment, the message allowing the initial registration or the location registration and that includes the information related to the connection restriction.
2. A user equipment comprising:
a transmitter configured to transmit, to a network node, a message requesting an initial registration or a location registration;
a receiver configured to receive a message allowing an initial registration or a location registration from the network node; and
a controller that does not attempt to connect to a network slice included in a registered network when the message allowing the initial registration or the location registration includes information related to a connection restriction that causes the user equipment to transition to a state in which the user equipment is registered and the user equipment is not allowed to use a service,
wherein, when the network node determines that the user equipment is connectable only to the Closed Access Group (CAG) cell and that the user equipment is disallowed to connect to any one of the one or more network slices, the receiver receives the message allowing the initial registration or the location registration and that includes the information related to the connection restriction.
