Abstract:
1. A mobile communication method in which a mobile station communicates with a radio base station by using a primary carrier and one or a plurality of secondary carriers having different carrier frequencies, ID, the method comprising the steps of: managing, at a mobile station, a MeasID which links a MeasObject and a ReportConfig to transmit a measurement report including a measurement result of the linked MeasObject to the radio base station, when the mobile station determines that the linked ReportConfig is satisfied; changing, at the mobile station, a link destination of a MeasID linking a MeasObject indicating a Second-Primary Component Carrier (S-PCC) to a MeasObiect indicating a Third-Primary Component Carrier (T-PCC) when the primary carrier changes from the S-PCC to the T-PCC, and the mobile station manages the MeasObject indicating the T-PCC; and releasing, at the mobile station, a MeasID linking, a MeasObiect indicating a carrier selected from among the plurality of secondary carriers third measurement ID, when the and when the selected carrier is changed to a non-configured carrier, wherein the mobile station does not measure the selected carrier until the mobile station acquires a new MeasID which links a new MeasObject and a new ReportConfig from the radio base station, the new MeasObject indicates a new carrier.
