Measurement report information transmission method and system

The invention discloses a measurement report information transmission method and a measurement report information transmission system, which relate to the technical field of digital mobile communication. The method provided by the invention comprises that: user equipment (UE) receives a measurement task from network side equipment, and transmits a measurement report at least comprising the absolute signal quality information and relative signal quality information of a cell specified on given carrier frequency to the network side equipment if the cell specified on the given carrier frequency corresponding to the measurement task meets the triggering conditions of the measurement task. By the technical scheme provided by the invention, the cell with relatively lower interference on a certain frequency point and a relatively better absolute signal can be determined from an aggregate carrier, a currently-aggregated component carrier of the UE is ensured to be optimal, the service experiences of a user are improved, the number of the measurement reports reported by a terminal is reduced, and the electrical energy and air interface resources of the terminal are saved.
