The embodiments of disclosure disclose a method and device for binding information. In the method, when an HGW is in a power-on state, first identification information from an subordinate device of the HGW is received; when it is determined that the HGW executes a BOOT operation and a business worksheet corresponding to the subordinate device of the HGW exists currently, second identification information is acquired from the HGW, wherein the second identification information is relevant configuration information which is registered in the HGW when the subordinate device of the HGW is connected to the HGW in the power-on state; and after the first identification information is successfully matched with the second identification information, logical identification information of the HGW is bound with the first identification information.
