A method for automatically configuring terminal equipment improves the performance of configuring and managing the terminal equipment. The method includes: after being powered on/reset, the terminal equipment reporting the current configuration information to the terminal management unit; the terminal management unit determining whether the configuration information reported by the terminal equipment is the same as the configuration information for the terminal equipment stored in the terminal management unit, if it is the same, terminating the current process, otherwise, transmitting the configuration information for the terminal equipment in the terminal management unit to the terminal equipment; the terminal equipment hence updating its own configuration information according to the received configuration information.
