Abstract

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.

Claims

1. A method for partially locking functions of a terminal, comprising:

receiving and analyzing, by a device management server, a partially locking request message to obtain a terminal identifier and a designated call identifier which are included in the message; and

sending 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.

2. The method according to claim 1, further comprising:

receiving, by the device management server, an unlocking request message and sending an unlocking command to the terminal, wherein the unlocking command instructs the terminal to modify the functional attribute to answering all calls.

3. A method for partially locking functions of a terminal, comprising:

receiving, by a terminal, a partially locking command sent by a device management server, and analyzing the partially locking command to obtain a designated call identifier carried in the command; and

modifying a functional attribute of the terminal per se to only answering a call corresponding to the designated call identifier.

4. The method according to claim 3, wherein the step of modifying the functional attribute of the terminal per se to only answering the call corresponding to the designated call identifier specifically comprises:

modifying a value of a preset incoming call IncomingCall node, and modifying the value of the IncomingCall node to the designated call identifier.

5. The method according to claim 3, further comprising:

modifying, by the terminal, the functional attribute of the terminal per se to answering all calls after receiving an unlocking command sent by the device management server.

13. The method according to claim 4, further comprising:

modifying, by the terminal, the functional attribute of the terminal per se to answering all calls after receiving an unlocking command sent by the device management server.

6. A method for partially locking functions of a terminal, comprising:

receiving and analyzing a partially locking request message by a device management server to obtain a terminal identifier and a designated call identifier which are included in the message; and

sending 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; and

receiving, by the terminal, the partially locking command sent by the device management server, and analyzing the partially locking command to obtain the designated call identifier carried in the command; and

modifying the functional attribute of the terminal per se to only answering the call corresponding to the designated call identifier.

7. A device management server, comprising:

a first receiving unit, configured to receive and analyze a partially locking request message to obtain a terminal identifier and a designated call identifier which are included in the message; and

a first sending unit, configured to send 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.

8. The device management server according to claim 7, further comprising:

a second receiving unit, configured to receive an unlocking request message sent by an owner of the terminal; and

a second sending unit, configured to send an unlocking command to the terminal, wherein the unlocking command instructs the terminal to modify the functional attribute to answering all calls.

9. A terminal, comprising:

a terminal side receiving unit, configured to receive a partially locking command sent by a device management server, and analyze the partially locking command to obtain a designated call identifier carried in the command; and

a first modifying unit, configured to modify its own functional attribute to only answering a call corresponding to the designated call identifier.

10. The terminal according to claim 9, wherein the first modifying unit realizes a function of modifying its own functional attribute to only answering the call corresponding to the designated call identifier through modifying a value of a preset incoming call IncomingCall node to the designated call identifier.

11. The terminal according to claim 9, further comprising:

a second modifying unit, configured to modify its own functional attribute to answering all calls after receiving an unlocking command sent by the device management server.

14. The terminal according to claim 10, further comprising:

a second modifying unit, configured to modify its own functional attribute to answering all calls after receiving an unlocking command sent by the device management server.

12. A system for partially locking functions of a terminal, comprising a device management server and a terminal:

the 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; and

the terminal receives the partially locking command sent by the device management server, and analyzes the partially locking command to obtain the designated call identifier carried in the command; and

modifies the functional attribute of the terminal per se to only answering the call corresponding to the designated call identifier.
