1. A user equipment used in a mobile communication system, the user equipment comprising:
a controller configured to, if the user equipment is in an RRC connected state, perform a predetermined function according to configuration parameters configured from a network, wherein
the controller is configured to,
acquire, from the network, a list including cell identifiers of cells forming a paging area of the user equipment in a specific state that is a state in which context information of the user equipment is maintained in the network, the specific state being a different state from the RRC connected state and an RRC idle state, and
in response to the transition of the user equipment from the RRC connected state to the specific state, invalidate at least a part of the configuration parameters,
the configuration parameters include dedicated configuration parameters individually configured to the user equipment,
the controller is configured to invalidate the dedicated configuration parameters in response to the transition of the user equipment from the RRC connected state to the specific state,
the controller is configured to receive, from the network, configuration information indicating whether transmission of a specific uplink signal is possible in the specific state,
the specific uplink signal is an uplink signal that the user equipment can transmit when the user equipment is in RRC connected state, and
the controller is configured to determine, based on the configuration information, whether to transmit the specific uplink signal when the user equipment is in the specific state.
