A measurement reporting method in a Carrier Aggregation, CA, Long Term Evolution, LTE, system, comprising: receiving, by a user equipment, UE, a Radio Resource Control, RRC, connection reconfiguration information from a network side; judging, by the UE, whether at least one component carrier and/or at least one measurement object meets a condition of triggering measurement reporting according to the RRC connection reconfiguration information; wherein the condition of triggering measurement reporting comprises that the measurement quantity is greater than a certain threshold for a duration TimeToTrigger, reporting, by the UE, measurement information of the at least one component carrier and/or measurement information of the at least one measurement object to the network side by a measurement reporting message, when the judging result is true, wherein the measurement object indicates a frequency; the measurement information includes a pre-defined strategy configured by the network side, a measurement quantity and carrier information and/or frequency information corresponding to the measurement quantity, wherein the carrier information and/or the frequency information is indicated by its own measurement identifier, a cell identifier, a carrier identifier or bitmap information, the measurement quantity is a single measurement quantity of the at least one component carrier and/or the at least one measurement object, and measurement quantities of multiple carriers or frequencies indicated by the measurement object, that satisfy the pre-defined strategy, wherein, the pre-defined strategy comprises that: the measurement quantity meets conditions to enter report lists, but does not reach time of TimeToTrigger, or the measurement quantity does not meet conditions to enter report lists, and does not reach the time of TimeToTrigger, wherein the conditions to enter report lists comprise that the measurement quantity is greater than the certain threshold. receiving, by a user equipment, UE, a Radio Resource Control, RRC, connection reconfiguration information from a network side; judging, by the UE, whether at least one component carrier and/or at least one measurement object meets a condition of triggering measurement reporting according to the RRC connection reconfiguration information; wherein the condition of triggering measurement reporting comprises that the measurement quantity is greater than a certain threshold for a duration TimeToTrigger, reporting, by the UE, measurement information of the at least one component carrier and/or measurement information of the at least one measurement object to the network side by a measurement reporting message, when the judging result is true, wherein the measurement object indicates a frequency; the measurement information includes a pre-defined strategy configured by the network side, a measurement quantity and carrier information and/or frequency information corresponding to the measurement quantity, wherein the carrier information and/or the frequency information is indicated by its own measurement identifier, a cell identifier, a carrier identifier or bitmap information, the measurement quantity is a single measurement quantity of the at least one component carrier and/or the at least one measurement object, and measurement quantities of multiple carriers or frequencies indicated by the measurement object, that satisfy the pre-defined strategy, wherein, the pre-defined strategy comprises that: the measurement quantity meets conditions to enter report lists, but does not reach time of TimeToTrigger, or the measurement quantity does not meet conditions to enter report lists, and does not reach the time of TimeToTrigger, wherein the conditions to enter report lists comprise that the measurement quantity is greater than the certain threshold. the measurement quantity meets conditions to enter report lists, but does not reach time of TimeToTrigger, or the measurement quantity does not meet conditions to enter report lists, and does not reach the time of TimeToTrigger, wherein the conditions to enter report lists comprise that the measurement quantity is greater than the certain threshold.
