and control means for executing, based on the collection/reporting control information, at least one of the collection and the reporting if execution determination information, which is related to at least one of the collection of the measurement information and the reporting of the measurement information to be executed by the local terminal, satisfies a given determination criterion. ## Claims ### Claim 1 A radio terminal comprising: a receiver configured to receive, from a radio network, configuration information for measurement logging, the configuration information including a PLMN-ID (Public Land Mobile Network Identity); and a processor configured to perform logging of measurement results when a first condition related to the PLMN-ID is satisfied, and a transmitter configured to transmit, to the radio network, a report of the logged measurement results when the first condition related to the PLMN-ID is satisfied. ### Claim 2 (depends on 1) The radio terminal according to claim 1, wherein the configuration information further includes area information, wherein the area information includes at least one of a Cell-ID and a location area to which the radio terminal belongs, wherein the processor is further configured to perform logging of measurement results when both of the first condition related to the PLMN-ID and a second condition related to the area information are satisfied. ### Claim 3 (depends on 2) The radio terminal according to claim 2, wherein the first condition is whether the a PLMN-ID of the radio terminal is same the PLMN-ID included in the configuration information, and the second condition is whether the radio terminal camp on a cell belonging to an area indicated by the area information included in the configuration information. ### Claim 4 (depends on 1) The radio terminal according to claim 1, wherein the processor is further configured to perform logging of measurement results based on a third condition related to usage of a memory implemented in the radio terminal for the logged measurement result. ### Claim 5 A radio network comprising: a transmitter configured to transmit, to a radio terminal, configuration information for measurement logging, the configuration information including a PLMN-ID (Public Land Mobile Network Identity); and a receiver configured to receive, from the radio terminal, a report of logged measurement results which have been logged by the radio terminal, wherein the configuration information causes the radio terminal to perform logging of measurement results when a first condition related to the PLMN-ID is satisfied, and to transmit, to the radio network, the report of logged measurement results when the first condition related to the PLMN-ID is satisfied. ### Claim 6 (depends on 5) The radio network according to claim 5, wherein the configuration information further includes area information, wherein the area information includes at least one of a Cell-ID and a location area to which the radio terminal belongs, wherein the logging of measurement results is performed by the radio terminal when both of the first condition related to the PLMN-ID and a second condition related to the area information are satisfied. ### Claim 7 (depends on 6) The radio network according to claim 6, wherein the first condition is whether the a PLMN-ID of the radio terminal is same the PLMN-ID included in the configuration information, and the second condition is whether the radio terminal camp on a cell belonging to an area indicated by the area information included in the configuration information. ### Claim 8 (depends on 5) The radio network according to claim 5, wherein the logging of measurement results is performed by the radio terminal based on a third condition related to usage of a memory implemented in the radio terminal for the logged measurement result. ### Claim 9 A method of a radio terminal comprising: receiving, from a radio network, configuration information for measurement logging, the configuration information including a PLMN-ID (Public Land Mobile Network Identity); logging measurement results when a first condition related to the PLMN-ID is satisfied; and transmitting, to the radio network, a report of the logged measurement results when the first condition related to the PLMN-ID is satisfied. ### Claim 10 A method of a radio network comprising: transmitting, to a radio terminal, configuration information for measurement logging, the configuration information including a PLMN-ID (Public Land Mobile Network Identity); and receiving, from the radio terminal, a report of the logged measurement results which have been logged by the radio terminal, wherein the configuration information causes the radio terminal to perform logging of measurement results when a first condition related to the PLMN-ID is satisfied, and to transmit, to the radio network, the report of the logged measurement results when the first condition related to the PLMN-ID is satisfied.
