A method for measuring signal quality of a cell in a mobile communication system, characterized by comprising: detecting, by a User Equipment, UE, a report status of a measurement task; stopping, by the UE, performing a current measurement task if the report status of the measurement task is that the current measurement task has been finished or will not continue being reported; continuing, by the UE, performing the current measurement task if the report status of the measurement task is that the current measurement task is not finished or will continue being reported; the method further comprising: A1, initially setting a status corresponding to an identifier of the current measurement task, the report status of the measurement task identified by the status being RUNNING; according to the identified report status of the measurement task, the UE continuing measuring cells on one or a group of frequencies indicated by a measurement object corresponding to the identifier of the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task is not finished or will continue being reported; and A2, determining that a report type corresponding to the identifier of the current measurement task is periodically-triggered reporting and updating the identified report status of the measurement task to be FINISH when a report accounting value is equal to or greater than and equal to a set maximum report time; according to the updated identified report status of the measurement task, the UE no longer measuring the cells on one or a group of frequencies indicated by the measurement object corresponding to the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task has been finished or will not continue being reported. detecting, by a User Equipment, UE, a report status of a measurement task; stopping, by the UE, performing a current measurement task if the report status of the measurement task is that the current measurement task has been finished or will not continue being reported; continuing, by the UE, performing the current measurement task if the report status of the measurement task is that the current measurement task is not finished or will continue being reported; the method further comprising: A1, initially setting a status corresponding to an identifier of the current measurement task, the report status of the measurement task identified by the status being RUNNING; according to the identified report status of the measurement task, the UE continuing measuring cells on one or a group of frequencies indicated by a measurement object corresponding to the identifier of the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task is not finished or will continue being reported; and A2, determining that a report type corresponding to the identifier of the current measurement task is periodically-triggered reporting and updating the identified report status of the measurement task to be FINISH when a report accounting value is equal to or greater than and equal to a set maximum report time; according to the updated identified report status of the measurement task, the UE no longer measuring the cells on one or a group of frequencies indicated by the measurement object corresponding to the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task has been finished or will not continue being reported. A1, initially setting a status corresponding to an identifier of the current measurement task, the report status of the measurement task identified by the status being RUNNING; according to the identified report status of the measurement task, the UE continuing measuring cells on one or a group of frequencies indicated by a measurement object corresponding to the identifier of the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task is not finished or will continue being reported; and A2, determining that a report type corresponding to the identifier of the current measurement task is periodically-triggered reporting and updating the identified report status of the measurement task to be FINISH when a report accounting value is equal to or greater than and equal to a set maximum report time; according to the updated identified report status of the measurement task, the UE no longer measuring the cells on one or a group of frequencies indicated by the measurement object corresponding to the current measurement task if it is detected that the report status of the current measurement task is that the current measurement task has been finished or will not continue being reported.
