Abstract

A method and system for implementing a user interface for providing a data service in a mobile client using a server with knowledge of the client'"'"'s hardware and software capabilities to modify data content and display rules for an improved user interface on the client. Data may be cached on the client to improve application response time and provide a standalone application capability for the client. The automatic conversion of newly developed applications to a plurality of clients with differing hardware and software capabilities reduces application software development and maintenance costs. Software updates and bug fixes can be deployed with the same method and system.

Claims

1. A method for providing rule set based applications by a first server for use by a client device in a client-server system comprising:

receiving a request for an application by the first server;

receiving at least one of a set of client device characteristics by the first server;

selecting at least one of a plurality of rule sets defining the requested application based on a similarity of the received at least one of the set of client device characteristics to a device characteristic associated with the rule set according to the received indication by the first server; and

sending the rule set to the client device by the first server to provide an application responsive to the request.

2. The method of claim 1 wherein the set of client device characteristics comprises at least one of (i) a client device'"'"'s carrier identification, (ii) a client device'"'"'s software operating system identification, (iii) a client device'"'"'s type identification, and (iv) a client device'"'"'s screen dimensions in pixels, (v) an application identifier for the client device, and (vi) an application state indicator for the client device.

3. The method of claim 1 wherein a rule set comprises at least one of static content that changes infrequently, dynamic content that changes frequently, formatting information for displaying content on the client device, and global information for storage on a client device for repeated use by the application.

4. The method of claim 1 further comprising:

selecting a first one of a plurality of meta rules based on a similarity of the received at least one of the set of client device characteristics to a device characteristic associated with the meta rule; and

translating the rule set according to the meta rule by the first server to conform to the at least one of the set of client device characteristics.

5. The method of claim 4 further comprising selecting a second one of the plurality of meta rules for a second translation of the rule set.

6. The method of claim 1, further comprising:

retrieving, by the first server, content from a content provider; and

combining, by the first server, the retrieved content with the rule set, wherein combining comprises associating an item of retrieved content with a display component in the rule set.

7. The method of claim 6, wherein retrieving comprises requesting content from the content provider, on the basis of a content identifier associated with the rule set.

8. The method of claim 6, wherein retrieving comprises requesting content from the content provider, on the basis of a content identifier associated with a content adapter of the first server.

9. The method of claim 6, wherein content comprises at least one of static content and dynamic content.

10. The method of claim 6, wherein content provider comprises a second server.

11. The method of claim 6, wherein the first and second servers are communicatively connected by a computer network.

12. The method of claim 1, further comprising:

converting, by the first server, the received indication from a first data format to a second data format for subsequent processing by the server; and

converting, by the server, the translated rule set from the second data format to the first data format, prior to sending the translated rule set to the client.

13. The method of claim 12, wherein the first data format comprises at least one of HTML, XML, and WML.

14. The method of claim 1, wherein the client is a mobile communication device.

15. The method of claim 14, wherein the mobile communication device is a cellular telephone.

16. A method for selecting a rule set defining an application in a client-server system comprising:

receiving, by a server from a client, an indication of client characteristics, the client characteristics comprising at least one of (i) a client'"'"'s carrier, (ii) a client'"'"'s software operating system, (iii) a client'"'"'s device type, and (iv) a client'"'"'s screen size; and

selecting, by the server, a rule set corresponding to the received indication if a corresponding rule set is available;

otherwise selecting a default rule set if a corresponding rule set is not available.

17. The method of claim 16 wherein the rule set is a meta rule set.

18. A method for generating a meta rule based on a client'"'"'s display screen size, comprising:

receiving x_c and y_c, the horizontal and vertical dimensions in pixels, respectively, of a client'"'"'s screen;

receiving x_r and y_r, the vertical and horizontal dimensions in pixels, respectively, of a reference screen from a rule set;

calculating a scaling factor based on at least one of the ratio of x_c/x_r and the ratio y_c/y_r; and

scaling designated display components of the rule set by the scaling factor.

19. The method of claim 18 wherein the scaling factor is 2−

x_c/x_r+y_c/y_r.
