Abstract
A radio terminal according to an embodiment is used in a mobile communication system. The radio terminal includes a controller configured to, if the radio terminal is in an RRC connected state, perform a predetermined function according to configuration parameters configured from a network. The controller is configured to invalidate at least a part of the configuration parameters in response to the transition of the radio terminal from the RRC connected state to a specific state. The specific state is a state in which signaling is reduced as compared with the RRC connected state and context information of the radio terminal is maintained in the network.
Claims18
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.
