Methods, devices and system for managing control relation of account and device

The invention relates to methods, devices and a system for managing a control relation of an account and a device, belonging to the field of electronic technique. The method comprises the steps of receiving a device binding request sent from a first terminal, wherein the device binding request carries a device identification of a target device broadcast by the target device and a first account identification of a login account of the first terminal; determining a second account identification corresponding to a master control account bound with the target device; sending a binding query message to a second terminal, which the account corresponding to the second account identification logs in, wherein the binding query message carries the first account identification and the device identification; and when a first acknowledgement message corresponding to the binding query message sent from the second terminal is received, recording the account corresponding to the first account identification as an auxiliary control account of the target device. Through adoption of the method, the efficiency of establishing the control relation of the account and the device can be improved.
