The invention relates to a wireless communication technology, in particular to a method, a system and a device for sending parameter information and measuring parameters, which are used for lowering the signaling cost of the system and lightening the burden of the system. The method for sending the parameter information of the embodiment of the invention comprises the following steps: determining a measurement control command corresponding to a terminal needing parameter measurement; sending public information in the measurement control command through broadcasting, and respectively sending the specific information in the corresponding measurement control command to the terminal, wherein the public information is the parameter information of which the number of the same parameter information in all the measurement control commands is not smaller than a threshold value, and the specific information is the parameter information in each measurement control command except the public information. By adopting the method for sending the parameter information of the embodiment of the invention, the signaling cost of the system can be lowered, the burden of the system can be lightened, and the utilization ratio of network resources is further improved.
