Abstract

The invention discloses a method, client and server for implementing the question and answer services. The method includes: by a first client, putting a question into presence information for publishing so that a second client obtains the presence information that contains the question; receiving an answer to the question sent by the second client through an instant message; and displaying the received answer together with the corresponding question. The invention fully utilizes the interpersonal network information in an instant messaging system, and implements the question and answer services based on the presence service and the instant messaging service in the instant messaging system. Therefore, users can ask questions and obtain answers conveniently based on the widely applied instant messaging system.

Claims

1. A method for implementing question and answer services in a computer network environment to helping a user raise questions and seek answers through popular instant messaging tools, comprising:

putting, by a first client in the network environment, a question into presence information for publishing so that a second client in the network environment obtains the presence information that carries the question;

receiving, by the first client, an answer to the question sent by the second client through an instant message; and

displaying to the user at the first client the answer together with the question.

2. The method of claim 1, wherein, after the first client publishes the presence information carrying a question, a third client obtains the presence information and publishes a presence information of the third client which carrying the question;

the second client obtains the question of the first client through the third client.

3. The method of claim 2, wherein the third client publishes the presence information carrying a user identifier of the first client, a question identifier and the question;

and the second client sends the answer and, the question identifier or the question, to the first client according to the user identifier.

4. The method of claim 3, wherein the second client sends a forwarding path of the question to the first client.

5. The method of claim 1, wherein, after the first client publishes the presence information, the question is obtained by the second client after being forwarded at least twice;

the second client sends the answer to the first client or a client of a node of the forwarding path via a instant message, wherein the instant message comprises forwarding path information of the question.

6. The method of claim 5, wherein, one node client of the forwarding path sends an instant message indicative of concern about the question;

and

the first client sends the answer to the node client after obtaining the answer.

7. The method of claim 1, wherein, the question published by the first client comprises a question identifier corresponding to the question;

the instant message sent by the second client comprises a question identifier corresponding to the answer; and

the first client matches the question identifier and the corresponding question, and displays the answer and the corresponding question together according to the received instant message.

8. The method of claim 7, wherein the answer is comprised in a message body of which the content type is answer;

when the first client detects that the received instant message comprises the message body of which the content type is answer, obtains the question identifier from the instant message, and obtains the corresponding question according to the question identifier.

9. The method of claim 1, wherein when the second client sends the answer to the first client by the instant message, the second client sends the answer corresponding to the question to the first client together.

10. The method of claim 1, wherein the first client publishes the answer contained in the presence information after receiving the answer.

11. The method of claim 1, wherein when the answer or the question is sent to a server, the server returns an address corresponding to the question or an address corresponding to the answer;

when publishing the question, the first client puts the address corresponding to the question into the presence information for publishing; and

when obtaining the question according to the address corresponding to the question, and the second client puts the address corresponding to the answer into the instant message when sending the answer.

12. The method of claim 1, wherein the first client publishes the question as a static presence information.

13. The method of claim 1, wherein the second client sends the answer to the first client by an instant message in session mode.

14. The method of claim 13, wherein the second client puts the question identifier into attribute of an SDP content of a SIP request, and sends the SIP request to the first client.

15. The method of claim 1, wherein the first client or presence server publishes the question on the question and answer websites or web blogs after the first client puts the question into the presence information for publishing.

16. The method of claim 1, wherein the number of the question published by the first client is not more than one;

when the first client detects that the content type of the received instant message is answer type, the first client displays the answer of the instant message and the question of the presence information published by the first client together.

17. The method of claim 1, wherein the presence information published by the first client comprises period of validity and/or urgent identifier.

24. One or more computer readable media, comprising logic encoded in the computer readable media, the logic when executed operable to implement the method according to the claim 1.

18. An instant messaging client in a computer network environment comprising:

a question presence information setting module, configured to receive a putting question, and publish the question contained in the presence information;

an answer instant message sending module, configured to obtain a question, receive a putting answer, and send a answer by an instant message; and

a question and answer displaying module, configured to display the answer in the instant message and the corresponding question.

19. The instant messaging client of claim 18, further comprising a question presence information forwarding module, configured to put the question into the presence information for publishing.

20. The instant messaging client of claim 18, further comprising a static question presence information, configured to receive input of a question, and publish the question to a server by XCAP protocol.

21. The instant messaging client of claim 18, further comprising a question and answer session module, configured to establish and process a session related to the question.

22. An instant messaging server, comprising:

a presence information processing module, configured to receive presence information that carries a question, and distribute the question; and

an instant message processing module, configured to receive and forward an instant message that carries an answer to the question.

23. A method for implementing the question and answer services in a computer network environment to help a user raise questions and seek answers through popular instant messaging tools comprising:

receiving and distributing at nodes of the network presence information that carries a question; and

receiving and forwarding at nodes of the network an instant message that carries an answer to the question.

25. One or more computer readable media, comprising logic encoded in the computer readable media, the logic when executed operable to implement the method according to the claim 23.
