Method, data transfer arrangement, server and terminal device for updating information in a terminal device
First Claim
1. A method for synchronizing information comprised by an application program in a client device from a media server maintaining up-to-date information, a) in which method the starting of the application program in the client device or a synchronization starting application causes checking of the up-to-date status of an application program in a client device before said piece of information is taken into use in the application program, b) in which method for checking the up-to-date status of the information the client device sends a synchronization starting message to a license server, which checks the information comprised by the synchronization starting message it received and sends back to the client device a reply message, and c) in which method said reply message always comprises the information of an up-to-date first license file and one of the following:
- a synchronization acceptance message or the information of a second license file, by using which the information of the application program can be updated to the client device from said media server.

Abstract
The invention relates to a method and data transfer arrangement for synchronizing information comprised by an application program in a client device. In the method, information comprised by an application program in the client device is updated from a media server maintaining up-to-date information. In addition, the data transfer arrangement comprises a separate license server, which contains two separate license files: the first license file and the second license file. The up-to-date status of information in the client device can be ensured by means of the first license file. The second license file comprises information by which the update required by the client device can be retrieved from a media server maintaining up-to-date information.

7. A data transfer arrangement for synchronizing information comprised by an application program in a client device,
a) in which data transfer arrangement, information comprised by an application program in a client device can be updated from a media server maintaining up-to-date information after the starting of said application program or synchronization starting application before said information is arranged to be taken into use in said application program, b) in which data transfer arrangement the client device has been arranged to send a synchronization starting message to the license server for checking the up-to-date status of the application program in a client device before the application program is used, and the license server has been arranged to check the information comprised by the synchronization message it has received and to send the checking result as a reply message back to the client device, and c) in which data transfer arrangement said reply message always comprises the information of an up-to-date first license file and one of the following files: - a synchronization acceptance message or the information of a second license file, by using which the information of the application program has been arranged to be updated to the client device from said media server.
