Abstract

A method, server and system for setting the size of email messages sent to mobile communications devices is provided. In one example embodiment, a method for for processing email messages sent to a mobile communications device is provided, comprising: receiving an email message having message content that contains at least a first type of content and a second type of content that is different from the first type; parsing the received email message to determine a quantity of the first type content contained in the email message until a predetermined first content quantity limit is reached, or until the end of the received email message is reached if the first content quantity limit is not reached first; and sending the message content that corresponds to however much of the received email message was parsed to mobile communications device.

Claims

1. A method for processing email messages for sending to a mobile communications device, comprising:

receiving an email message having message content that contains at least a first type of content and a second type of content that is different from the first type;

parsing the received email message to determine a quantity of the first type of content contained in the email message until a predetermined first content quantity limit is reached, or until the end of the received email message is reached if the first content quantity limit is not reached first; and

sending email message content that corresponds to however much of the received email message was parsed to a mobile communications device.

2. The method of claim 1 wherein the first type of content is viewable text characters.

3. The method of claim 2 wherein the predetermined first content quantity limit is a predetermined number of viewable text characters and parsing the received email message includes counting the viewable text characters in the email message until the predetermined number of viewable text characters is reached.

4. The method of claim 2 wherein the predetermined first content quantity limit is a predetermined number of viewable text lines and parsing the received email message includes counting the viewable text characters in the email message until the predetermined number of viewable text lines is reached.

5. The method of claim 2 wherein the email message includes content expressed in a formatting language, the second type of content including non-viewable formatting characters providing formatting information for the viewable text characters.

6. The method of claim 5 wherein the formatting language corresponds to one of RTF (Rich Text Format), XML (Extensible Markup Language), HTML (HyperText Markup Language), XHTML (Extensible HyperText Markup Language) or SGML (Standard Generalized Markup Language).

7. The method of claim 1 wherein the email message content that is sent after parsing includes both the first type of content and the second type of content.

8. The method of claim 1 comprising determining the predetermined first content quantity limit in dependence on a device class for the mobile communications device or a class of the network in which the mobile communications device is operating.

9. The method of claim 1 comprising, prior to sending the email message content, applying a further content quantity limit and processing the email message content to reduce a size thereof if the further content quantity limit is reached.

10. The method of claim 9 wherein the further content quantity limit is applied to a combined size of both the first type of content and the second type of content.

11. The method of claim 9 wherein the further content quantity limit is applied to the second type of content.

12. The method of claim 1 comprising determining the predetermined first content quantity limit by conducting a usability study.

13. The method of claim 1 wherein the predetermined first content quantity limit is selectively set for an individual user.

14. The method of claim 1 wherein the received email message content includes markup elements that comprise viewable text as the first type of content and markup characters providing formatting information for the viewable text as the second type of content, and parsing the received email message comprises sequentially parsing each of the markup elements to determine an amount of viewable text therein.

22. The wireless connector system of claim 14 wherein the system is implemented on a computer server.

15. A wireless connector system for processing and forwarding email messages to mobile communications devices located within a wireless network, the wireless connector system being configured for:

(i) receiving an email message having message content that contains at least a first type of content and a second type of content that is different from the first type;

(ii) parsing the received email message to determine a quantity of the first type of content contained in the email message until a predetermined first content quantity limit is reached, or until the end of the received email message is reached if the first content quantity limit is not reached first; and

(iii) sending email message content that corresponds to however much of the received email message was parsed to a mobile communications device.

16. The wireless connector system of claim 15 wherein the first type of content is viewable text characters, the predetermined first content quantity limit is a predetermined number of viewable text characters, and parsing the received email message includes counting the viewable text characters in the email message until the predetermined number of viewable text characters is reached.

17. The wireless connector system of claim 15 wherein the received email message includes content expressed in a formatting language, the second type of content including non-viewable formatting characters.

18. The wireless connector system of claim 15 wherein the predetermined first content quantity limit is determined in dependence on a device class for the mobile communications device or a class of the network in which the mobile communications device is operating.

19. The wireless connector system of claim 15 wherein prior to sending the email message content, a further content quantity limit is applied and the email message content is processed to reduce a size thereof if the further content quantity limit is reached.

20. The wireless connector system of claim 19 wherein the further content quantity limit is applied to a combined size of both the first type of content and the second type of content.

21. The wireless connector system of claim 19 wherein the further content quantity limit is applied to the second type of content.

23. A computer program product comprising a computer readable medium storing instructions implementable by a computer system for processing and forwarding email messages to mobile communications devices located within a wireless network, the stored instructions including instructions for:

receiving an email message having message content that contains at least a first type of content and a second type of content that is different from the first type;

parsing the received email message to determine a quantity of the first type of content contained in the email message until a predetermined first content quantity limit is reached, or until the end of the received email message is reached if the first content quantity limit is not reached first; and

sending email message content that corresponds to however much of the received email message was parsed to a mobile communications device.
