Abstract
A UE 200 operates as any one of a plurality of categories according to capability. The UE 200 includes: an attach processing unit 220 that performs attaching to a core network; an operation control unit 230 that causes the UE 200 to operate as a restricted category whose capability is restricted as compared to a normal category; and a category notification unit 240 that notifies the core network of a category in which the UE 200 is operating at the time of the attaching or after the attaching.
Claims2
A network device constituting a core network, the network device comprising:
- a category receiver that receives, when a category of a user equipment operating as any one of a plurality of categories according to capability is switched after the user equipment is attached to the core network, the category in which the user equipment is operating after switching;
- and
- a category transferrer that transfers the category received by the category receiver to a serving gateway, which transfers the category received from the category transferrer of the network device to a packet data network gateway,
- wherein the network device is a Mobility Management Entity.
