Method, system and device for managing customer premises equipment

摘要

The present invention provides a method, a system and a device for managing Customer Premises Equipment (CPE). The method includes: an Auto-Configuration Server (ACS) designates a first designated instance number for a first instance object, and sends to the CPE a message carrying the first designated instance number for the first instance object. The message is used to notify the CPE to take the first designated instance number as the instance number for the first instance object. By this method, when the ACS creates the same instance object for a plurality of CPEs, the same instance number can be designated to the same instance object for the respective CPEs. In this way, the same instance object can be invoked by using the same instance number without querying and judging each of the CPEs, thus lightening the workload of the management of CPE by ACS.
