Methods and systems for screening incoming calls

1. A method for screening incoming calls for use in a device having telecommunication capability, comprising:

receiving an incoming call from a caller;

generating a prompt to the caller in response to the incoming call;

receiving a response corresponding to the prompt from the caller;

determining whether the response conforms to a specific answer;

if so, driving the device to indicate the reception of the incoming call; and

if the response does not conform to the specific answer, re-generating the prompt to the caller, re-receiving a response corresponding to the prompt from the caller, and determining whether the response conforms to the specific answer.

2. The method of claim 1 further comprising generating the prompt by generating a first voice or a text message to the caller.

3. The method of claim 1 further comprising receiving the response corresponding to the prompt by receiving a second voice from the caller.

4. The method of claim 3 further comprising:

recognizing the second voice using a voice recognition technology to obtain an answer corresponding to the second voice; and

determining whether the answer conforms to the specific answer.

5. The method of claim 4 further comprising recording the second voice.

6. The method of claim 5 further comprising providing an interface for selecting playback of the second voice if the answer conforms to the specific answer.

7. The method of claim 1 further comprising providing an interface prompting the caller to leave a message if the response conforms to the specific answer.

8. The method of claim 1 further comprising receiving the response corresponding to the prompt by receiving a keystroke input from the caller.

9. The method of claim 8 further comprising determining whether the keystroke input conforms to the specific answer.

10. The method of claim 1 further comprising vibrating the device, displaying text or images, or ringing to indicate the reception of the incoming call.

11. The method of claim 1 , further comprising rejecting the incoming call or prompting the caller to leave a message if the wrong frequency of the response reaches a predefined number.

12. The method of claim 1 further comprising:

determining whether a caller ID of the incoming call is in a blacklist; and

if so, rejecting the incoming call.

13. The method of claim 1 further comprising:

determining whether a caller ID of the incoming call is in an address book or a calling history list; and

if so, directly driving the device to indicate the reception of the incoming call.

14. A system for screening incoming calls, comprising a processing unit receiving an incoming call from a caller, generating a prompt to the caller in response to the incoming call, receiving a response corresponding to the prompt from the caller, determining whether the response conforms to a specific answer, if so, driving the device to indicate the reception of the incoming call using a manner, and if the response does not conform to the specific answer, re-generating the prompt to the caller, re-receiving a response corresponding to the prompt from the caller, and determining whether the response conforms to the specific answer.

15. The system of claim 14 wherein the processing unit further generates the prompt by generating a first voice or a text message to the caller.

16. The system of claim 14 wherein the response corresponding to the prompt comprises a second voice.

17. The system of claim 16 wherein the processing unit further recognizes the second voice using a voice recognition technology to obtain an answer corresponding to the second voice, and determines whether the answer conforms to the specific answer.

18. The system of claim 17 wherein the processing unit further records the second voice.

19. The system of claim 18 further comprising a voice output unit, and the processing unit further provides an interface for selecting playback of the second voice via the voice output unit if the answer conforms to the specific answer.

20. The system of claim 14 wherein the processing unit further provides an interface prompting the caller to leave a message if the response conforms to the specific answer.

21. The system of claim 14 wherein the response corresponding to the prompt comprises a keystroke input.

22. The system of claim 21 wherein the processing unit further determines whether the keystroke input conforms to the specific answer.

23. The system of claim 14 wherein the processing unit further indicates the reception of the incoming call by vibration, displaying text or images, or ringing.

24. The system of claim 14 , wherein the processing unit further rejects the incoming call or prompts the caller to leave a message if the wrong frequency of the response reaches a predefined number.

25. The system of claim 14 wherein the processing unit further determines whether a caller ID of the incoming call is in a blacklist, and if so, rejects the incoming call.

26. The system of claim 14 wherein the processing unit further determines whether a caller ID of the incoming call is in an address book or a calling history list, and if so, directly drives the device to indicate the reception of the incoming call.

27. A machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a method for screening incoming calls, the method comprising:

receiving an incoming call from a caller;

generating a prompt to the caller in response to the incoming call;

receiving a response corresponding to the prompt from the caller;

determining whether the response conforms to a specific answer;

if so, driving the device to indicate the reception of the incoming call, and

if the response does not conform to the specific answer, re-generating the prompt to the caller, re-receiving a response corresponding to the prompt from the caller, and determining whether the response conforms to the specific answer.
