1. A user equipment capable of performing a local IP access to a first network in a communication system, the communication system enabling the user equipment to perform a local IP access to the first network while connecting the user equipment to a second network that is physically different from the first network, the user equipment comprising: a unit that transmits, to a packet data network for local IP access placed in a core network, information necessary for authentication of a local IP access to the first network when establishing a first packet data network connection with the packet data network for local IP access capable of dealing with a local IP access by the user equipment; a unit that performs, when the packet data network for local IP access performs authentication processing concerning the local IP access by the user equipment to the first network and validity thereon is confirmed, a local IP access to the first network via the first packet data network connection and a second packet data network connection, the second packet data network connection being established by the packet data network for local IP access between the first network and the packet data network for local IP access; a unit that transmits, when a local IP access is performed to a third network to which the user equipment is local-IP accessible using the packet data network for local IP access, or when the local IP access is already performed, to the packet data network for local IP access, an inter-network connection request including information to set a connection between the first network and the third network; and a unit that controls, when a communication is performed between a node in the first network and a node in the third network, a communication operation of the node in the first network and a communication operation of the node in the third network.
