Method, Device and System for Partially Locking Functions of Terminal

A method for partially locking functions of a terminal is disclosed, which includes the following steps: a device management server receives and analyzes a partially locking request message to obtain a terminal identifier and a designated call identifier which are included in the message; and sends a partially locking command to a terminal corresponding to the terminal identifier, wherein the partially locking command carries the designated call identifier and instructs the terminal to modify a functional attribute of the terminal per se to only answering a call corresponding to the designated call identifier. Another two methods for partially locking functions of a terminal, a device management server, a terminal, and a system for partially locking functions of a terminal are further disclosed. The disclosure can solve the problem in the prior art that: a call channel and other resources are occupied and the security of information of the terminal cannot be guaranteed as the terminal can still answer all incoming calls after functions of the terminal are partially locked.
