The invention discloses a processing method and device of a MMS (multimedia messaging service) notification message, and a MMS receiving system. The method is characterized by comprising the following steps: receiving the MMS notification message, and adding the MMS notification message in a preset processing queue; setting a processing identifier for identifying whether a circuit exchange domain/packet exchange domain service in processing is existent at present; judging whether the circuit exchange domain/packet exchange domain service in processing is existent at present according to the processing identifier, if the result is yes, maintaining the MMS notification message in the processing queue to waiting for processing; otherwise, reading the leading MMS notification message from the processing queue to process. Through the adoption of the method and device disclosed by the invention, the integral performance of the terminal MMS service is improved.
