Abstract

Techniques for interacting with a client process on a mobile device connected to a network over a wireless link includes managing information at a mobile applications server executing on a platform connected to the network. The information includes device profile information about the mobile device. First data is received from an application. The first data describes graphical elements for display on the mobile device. It is determined whether the first data exceeds a capacity of the mobile device based on the device profile information. If it is determined that the first data exceeds the capacity, then a subset of the first data is formed that does not exceed the capacity of the mobile device. The subset of the first data is sent to the client process. If it is determined that an external converter does not convert using a particular format, then a first description of graphical elements is converted internally into a second description using the particular format. Second data including the second description is sent to the client process. These techniques allow network-based services to be made readily available to a wide range of mobile devices without having to explicitly program each application for providing one or more network-based services to support all forms of mobile devices.

Claims

1. A machine-readable storage medium storing instructions executable by a computer system, the instructions comprising:

instructions that cause the computer system to generate output data expressed in a first markup language, wherein the output data is to be presented via a mobile client device;

instructions that cause the computer system to determine one or more characteristics of the mobile client device; and

instructions that cause the computer system to convert the output data from the first markup language to a second markup language appropriate for the mobile client device, wherein the converting is performed based on the one or more characteristics.

2. The machine-readable storage medium of claim 1 wherein the first markup language is eXtensible Markup Language (XML).

3. The machine-readable storage medium of claim 2 wherein the second markup language is selected from a group consisting of:

Hypertext Markup Language (HTML), Handheld Device Markup Language (HDML), Wireless Markup Language (WML), and Voice Markup Language (VoiceML).

4. The machine-readable storage medium of claim 1 wherein the output data comprises data defining a user interface page, and wherein the output data is to be displayed to the user via a display of the mobile client device.

5. The machine-readable storage medium of claim 1 wherein the output data is to be reproduced aurally to the user via a speaker of the mobile client device.

6. The machine-readable storage medium of claim 1 wherein the instructions further comprise instructions that cause the computer system to maintain a device profile database configured to store characteristics for different types of mobile client devices, wherein determining one or more characteristics of the mobile client device comprises retrieving a profile for the mobile client device from the device profile database.

7. The machine-readable storage medium of claim 1 wherein the mobile client device is selected from a group consisting of:

personal digital assistant (PDA), laptop computer, and cellular phone.

8. A method comprising:

generating, by a computer system, output data expressed in a first markup language, wherein the output data is to be presented via a mobile client device;

determining, by the computer system, one or more characteristics of the mobile client device; and

converting, by the computer system, the output data from the first markup language to a second markup language appropriate for the mobile client device, wherein the converting is performed based on the one or more characteristics.

9. The method of claim 8 wherein the first markup language is eXtensible Markup Language (XML).

10. The method of claim 9 wherein the second markup language is selected from a group consisting of:

Hypertext Markup Language (HTML), Handheld Device Markup Language (HDML), Wireless Markup Language (WML), and Voice Markup Language (VoiceML).

11. The method of claim 8 wherein the output data comprises data defining a user interface page, and wherein the output data is to be displayed to the user via a display of the mobile client device.

12. The method of claim 8 wherein the output data is to be reproduced aurally to the user via a speaker of the mobile client device.

13. The method of claim 8 further comprising:

maintaining a device profile database configured to store characteristics for different types of mobile client devices, wherein determining one or more characteristics of the mobile client device comprises retrieving a profile for the mobile client device from the device profile database.

14. A system comprising:

a processor configured to;

generate output data expressed in a first markup language, wherein the output data is to be presented via a mobile client device;

determine one or more characteristics of the mobile client device; and

convert the output data from the first markup language to a second markup language appropriate for the mobile client device, wherein the converting is performed based on the one or more characteristics.

15. The system of claim 14 wherein the first markup language is eXtensible Markup Language (XML).

16. The system of claim 15 wherein the second markup language is selected from a group consisting of:

Hypertext Markup Language (HTML), Handheld Device Markup Language (HDML), Wireless Markup Language (WML), and Voice Markup Language (VoiceML).

17. The system of claim 14 wherein the output data comprises data defining a user interface page, and wherein the output data is to be displayed to the user via a display of the mobile client device.

18. The system of claim 14 wherein the output data is to be reproduced aurally to the user via a speaker of the mobile client device.

19. The system of claim 14 wherein the processor is further configured to:

maintain a device profile database configured to store characteristics for different types of mobile client devices, wherein determining one or more characteristics of the mobile client device comprises retrieving a profile for the mobile client device from the device profile database.
