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 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 viewable text characters and non-viewable formatting characters, the non-viewable formatting characters providing formatting information for the viewable text characters;

parsing the received email message by counting the viewable text characters and ignoring the non-viewable formatting characters either until a viewable text limit is reached or until the end of the received email message is reached;

applying a message size limit;

responsive to reaching the message size limit, processing email message content to reduce a size thereof, the processing including applying the message size limit to the non-viewable formatting characters; and

sending the email message content to a mobile communications device.

2. The method of claim 1 wherein the viewable text limit is a predetermined number of viewable text characters and the 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.

3. The method of claim 1 wherein the viewable text limit is a predetermined number of viewable text lines and the 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.

4. The method of claim 1 wherein the non-viewable formatting characters are expressed in a formatting language.

5. The method of claim 4 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).

6. The method of claim 1 wherein the email message content includes both the viewable text characters and the non-viewable formatting characters.

7. The method of claim 1 comprising determining the viewable text 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.

8. The method of claim 1 wherein the processing comprises applying the message size limit to a combined size of both the viewable text characters and the non-viewable formatting characters.

9. The method of claim 1 comprising determining the viewable text limit by conducting a usability study.

10. The method of claim 1 wherein the viewable text limit is selectively set for an individual user.

11. 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 viewable text characters and non-viewable formatting characters, the non-viewable formatting characters providing formatting information for the viewable text characters;

(ii) parsing the received email message by counting the viewable text characters and ignoring the non-viewable formatting characters either until a viewable text limit is reached or until the end of the received email message is reached; and

(iii) applying a message size limit;

(iv) responsive to reaching the message size limit, processing email message content to reduce a size thereof, the processing including applying the message size limit to the non-viewable formatting characters; and

(v) sending the email message content to a mobile communications device.

12. The wireless connector system of claim 11 wherein the viewable text limit is a predetermined number of viewable text characters, and the 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.

13. The wireless connector system of claim 11 wherein the non-viewable formatting characters are expressed in a formatting language.

14. The wireless connector system of claim 11 further configured for determining the viewable text 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.

15. The wireless connector system of claim 11 further configured for applying the message size limit to a combined size of both the viewable text characters and the non-viewable formatting characters.

16. The wireless connector system of claim 11 wherein the system is implemented on a computer server.

17. A non-transitory 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 viewable text characters and non-viewable formatting characters, the non-viewable formatting characters providing formatting information for the viewable text characters;

parsing the received email message by counting the viewable text characters and ignoring the non-viewable formatting characters either until a viewable text limit is reached or until the end of the received email message is reached;

applying a message size limit;

responsive to reaching the message size limit, processing email message content to reduce a size thereof, the processing including applying the message size limit to the non-viewable formatting characters; and

sending the email message content to a mobile communications device.
