Abstract

Systems and methods for operating in connection with mobile devices are described. The mobile devices may move between online and offline areas. In some instances, a prediction may be made as to when a mobile device will enter an offline area. The prediction may be based on sensor information. Data or a key may be transferred to the mobile device prior to entering the offline area.

Claims

1. A server for operating in connection with a client terminal, the server comprising:

circuitry configured to;

receive sensor information from the client terminal;

predict, based on the sensor information and a service area map, an offline entry time at which the client terminal will enter an offline area;

automatically select data for use by the client terminal while offline based on user history of the client terminal;

determine a time duration needed to transmit the data to the client terminal; and

initiate transmission of the data from the server at a transmission initiation time based on the offline entry time and the time duration, wherein the transmission is performed on a limited part of the data in a range permitted for display on the client terminal.

2. The server of claim 1, wherein the circuitry is further configured to generate a predicted path of movement of the client terminal based at least partially on the sensor information, and wherein the prediction of the offline entry time is based at least in part on the predicted path of movement.

3. The server of claim 2, wherein the circuitry is further configured to execute a communication prediction algorithm to compare communication information indicative of communication status of the client terminal against the predicted path of movement of the client terminal.

4. The server of claim 1, wherein the data is encrypted data, and wherein the circuitry is further configured to send to the client terminal a key configured to decrypt the encrypted data.

5. The server of claim 1, wherein the sensor information comprises a history of user operations performed on the client terminal.

6. The server of claim 1, wherein the circuitry is further configured to:

attempt a connection with the client terminal upon determination of an online return prediction time; and

transmit a request to the client terminal for deletion of the data transmitted before the client terminal went offline area.

7. The server of claim 1, wherein the circuitry is further configured to generate a predicted path of movement of the client terminal based on the sensor information, and by using previous movement history of the user who is using the client terminal or movement history of other users.

8. The server of claim 1, wherein the circuitry is further configured to select data for use by the client terminal while offline based on a manual operation of the user in accordance with a degree of necessity of the data on the client terminal.

9. A method of operating a server comprising circuitry and configured to communicate with a client terminal, the method performed by the circuitry comprising:

receiving sensor information from the client terminal;

predicting, based on the sensor information and a service area map, an offline entry time at which the client terminal will enter an offline area;

automatically selecting data for use by the client terminal while offline based on user history of the client terminal;

determining a time duration needed to transmit the data to the client terminal; and

initiating transmission of the data from the server at a transmission initiation time based on the offline entry time and the time duration, wherein the transmission is performed on a limited part of the data in a range permitted for display on the client terminal.

10. The method of claim 9, further comprising generating a predicted path of movement of the client terminal based at least partially on the sensor information, and wherein predicting the offline entry time is based at least in part on the predicted path of movement.

11. The method of claim 10, further comprising executing a communication prediction algorithm to compare communication information indicative of communication status of the client terminal against the predicted path of movement of the client terminal.

12. The method of claim 9, wherein the data is encrypted data, and wherein the method further comprises sending to the client terminal a key configured to decrypt the encrypted data.

13. The method of claim 9, wherein the sensor information comprises a history of user operations performed on the client terminal, and wherein predicting the offline entry time is performed based on the history of user operations performed on the client terminal.

14. A non-transitory computer readable storage medium encoded with instructions which, when executed by a server coupled to a client terminal, cause the server to perform a method comprising:

receiving sensor information from the client terminal;

predicting, based on the sensor information and a service area map, an offline entry time at which the client terminal will enter an offline area;

automatically selecting data for use by the client terminal while offline based on user history of the client terminal;

determining a time duration needed to transmit the data to the client terminal; and

initiating transmission of the data from the server at a transmission initiation time based on the offline entry time and the time duration, wherein the transmission is performed on a limited part of the data in a range permitted for display on the client terminal.

15. The non-transitory computer readable storage medium of claim 14, wherein the method further comprises generating a predicted path of movement of the client terminal based at least partially on the sensor information, and wherein predicting the offline entry time is based at least in part on the predicted path of movement.

16. The non-transitory computer readable storage medium of claim 15, wherein the method further comprises executing a communication prediction algorithm to compare communication information indicative of communication status of the client terminal against the predicted path of movement of the client terminal.

17. The non-transitory computer readable storage medium of claim 14, wherein the data is encrypted data, and wherein the method further comprises sending to the client terminal a key configured to decrypt the encrypted data.

18. The non-transitory computer readable storage medium of claim 14, wherein the sensor information comprises a history of user operations performed on the client terminal, and wherein predicting the offline entry time is performed based on the history of user operations performed on the client terminal.
