The invention relates to the technical field of Bluetooth, in particular to a method for controlling a mobile terminal through a multifunctional Bluetooth watch. The method comprises the steps that the Bluetooth equipment is turned on, the mobile terminal is searched for, and connection between the Bluetooth watch and the mobile terminal is established; the Bluetooth watch conducts monitoring on the mobile terminal through an APK on the mobile terminal; when it is monitored that the mobile terminal has a message, the message is encoded, the encoded message is sent to the Bluetooth watch through an object exchange protocol; the Bluetooth watch decodes the encoded message and judges the type of the message, and preset control is conducted according to the type of the message. According to the method for controlling the mobile terminal through the multifunctional Bluetooth watch, the Bluetooth watch is connected with the mobile terminal through the Bluetooth protocol, when the mobile terminal has the message, the APK on the mobile terminal sends the message to the Bluetooth watch, the Bluetooth watch conducts preset control on the mobile terminal according to the type of the message, therefore, relevant messages on the mobile terminal can be processed in time conveniently and multiple functions are achieved.
