The invention provides a multi-band measurement processing method and system for a terminal. The method comprises the steps of obtaining identification information of the terminal; and obtaining a measurement strategy matching the identification information from a configuration table, thereby sending a frequency point measurement message according to the measurement strategy, wherein the configuration table comprises the identification information of the terminal, the measurement strategy, first information and second information, the first information is used for indicating bands supported by the terminal, and the second formation is used for indicating whether the terminal supports an overlapped spectrum mutual-identification function or not. Through application of the method and the system, the problem that an existing frequency point conversion mode is overlong in time delay and high in call drop rate when overlapped bands exist in the multiple bands is solved.
