Abstract

Disclosed is a method and device for keeping persistency while switching between modalities, which include: (1) searching out the last operation state of the application service accessed by the user from the user history, in response to a request for accessing an application service from a user; (2) connecting to the application service and continuing to execute the application service from the last operation state; (3) updating the last operation state in the user history based on the execution result of the application service. A user could flexibly selects different favorable terminal to continue with unfinished application service by adopting the invention.

Claims

1. A method for accessing an application service in a pervasive network comprising:

in response to a user request to access the application service, recalling the last operation state of the application service from a user history;

connecting to the application service and continuing to execute the application service from the last operation state; and

updating the last operation state in the user history based on the execution result of the application service.

2. The method according to claim 1 further comprising:

returning the execution result to the user using a contact method appropriate to the user.

3. The method according to claim 2, wherein the contact method is that which is used by the user when requesting access to the application service.

4. The method according to claim 2, wherein the contact method is selected from a plurality of contact methods pre-registered by the user.

5. Apparatus for providing access to an application service in a pervasive network comprising:

means for recalling the last operation state of the application service accessed by the user from the user history responsive to a request for accessing an application service from a user;

means for connecting to said application service and continuing to execute said application service from said last operation state; and

means for updating the last operation state in the user history based on said execution result of said application service.

6. The apparatus according to claim 5, further comprising:

means for presenting said execution result to said user using a contact method appropriate to the user.

7. The apparatus according to claim 6, wherein the contact method is that which is used by said user when requesting access to said application service.

8. The apparatus according to claim 6, wherein the contact method is selected from a plurality of methods pre-registered by said user.

9. Apparatus for keeping persistency in a computer network comprising:

a user history module for recording the historical call information of at least one user for at least one application service based on the user ID;

logon control module for identifying or verifying the user requesting access to an application service, retrieving the historical call information of the user for the application service from the user history module, and extracting the call ID of the last operation of the user for the application service from the historical call information;

a session management module for connecting to the application service and executing the application service based on the historical call information, and for updating the historical call information recorded in the user history module based on the execution result; and

a connection management module, for setting up the connection to the session management module based on the extracted call ID.

10. The apparatus according to claim 9, further comprising:

a user registrar module for registering information on at least one device used by a user for connection, the connection management module being operable to select one device from the user register module for the user to receive the execution result of the application service.

11. The apparatus according to claim 10, further comprising:

means for presenting the execution result to the selected device.

12. The apparatus according to claim 11, wherein said terminal is the one used by the user when requesting access to the application service.

13. The apparatus according to claim 11, wherein the device is selected from a plurality of terminals pre-registered by the user.
