Abstract: A method in which a user apparatus including at least operation modes of a connection mode (CONN) and an idle mode (IDLE), includes: a measurement unit that measures radio quality in the idle mode according to measurement target information indicating that the user apparatus is set beforehand to report a measurement value of radio quality to a base station; a storage unit that stores the measurement target information and the measurement value of radio quality measured by the measurement unit; and a transmission unit that transmits, in the connection mode, an indicator indicating that there is the measurement value of radio quality to the base station, and transmits a report signal including the measurement value of radio quality according to a request from the base station, wherein when a predetermined condition for deleting measurement target information (configuration flush condition) is satisfied, the storage unit deletes the measurement target information.

Abstract: A user apparatus including at least operation modes of a connection mode and an idle mode, includes: a measurement unit that measures radio quality in the idle mode according to measurement target information (Config#m, Config#n) indicating that the user apparatus is set beforehand to report a measurement value of radio quality to a management node; a storage unit that stores the measurement target information and the measurement value of radio quality measured by the measurement unit; and a transmission unit that transmits, in the connection mode, an indicator indicating that there is the measurement value of radio quality to the management node, and transmits a report signal including the measurement value of radio quality to the management node according to a request from the management node, wherein, when the user apparatus obtains new measurement target information (Config#n), the storage unit stores the new measurement target information according to a predetermined updating rule (reconfiguration model)

Abstract: User equipment having operating modes of at least a connected mode (CONN) and an idle mode (IDLE) includes a measurement unit configured to measure radio quality in the idle mode in accordance with measurement target information indicating that the user equipment is preset to report a measurement value of the radio quality to a base station, a storage unit configured to store the measurement target information and the measurement value of the radio quality measured by the measurement unit and a transmitting unit configured to, if a predefined report condition (log exist condition, FIG. 3) is satisfied, transmit an indicator indicative of presence of the measurement value of the radio quality to the base station in the connected mode and in response to a request from the base station, transmit a report signal including the measurement value of the radio quality.
