Abstract

A mobile communications device for the display of an incrementally received message includes a message viewer application for scanning the received portions of the message. On determination that the received portion of the message includes a first displayable portion of the message content, the system signals to a message server to halt the message server from forwarding further portions of the message content. The system provides a mechanism for the user of the mobile communications device to cause the mobile communications device to further signal the message server to recommence the forwarding of further portions of the secure message content to permit the verification of the e-mail based on the further portions of the secure message content.

Claims

1. A method for receiving a message on a mobile communications device, the method comprising:

receiving, at the mobile communications device, a first segment of the message, the first segment comprising at least a portion of a displayable message content portion comprised in a body of the message, said displayable message content portion being delimited within the body of the message by a predefined indicator identifying an end of the displayable message content portion;

scanning, at the mobile communications device, the first segment for the predefined indicator;

automatically receiving one or more further segments of the message at the mobile communications device and

scanning said one or more further segments of the message for the predefined indicator at the mobile communications device until the predefined indicator is found in a received segment; and

automatically transmitting a command to the server to halt transmission of any further segments of the message once the predefined indicator is found.

2. The method of claim 1, wherein the first and any further segment is transmitted to the mobile communications device by a server, the method further comprising, prior to said automatically receiving one or more further segments, automatically transmitting a command to the server to transmit the further segments of the message.

3. The method of claim 2, wherein transmitting the command to transmit the further segments is carried out only if the predefined indicator has not yet been found.

4. The method of claim 1, wherein said transmitting the command to halt transmission is carried out prior to receiving any further segment.

5. The method of claim 1, wherein each further segment is scanned prior to receiving a subsequent further segment.

6. The method of claim 1, wherein said scanning the first segment for the predefined indicator, said automatically receiving one or more further segments, and said scanning said one or more further segments for the predefined indicator are carried out for a message being currently viewed at the mobile communications device.

7. The method of claim 1, wherein said scanning the first segment for the predefined indicator, said automatically receiving one or more further segments, and said scanning said one or more further segments for the predefined indicator are carried out for a message not currently being viewed at the mobile communications device.

8. The method of claim 1, wherein the displayable message content portion comprises one of plaintext, HTML, or RTF formatted content.

9. The method of claim 1, wherein the delimiter comprises an identifier of a content format of the displayable message content portion.

10. The method of claim 1 wherein the message further comprises a non-displayable message content portion, such that the displayable message content portion is located within the message before the non-displayable message content portion.

11. The method of claim 1 wherein the message further comprises at least one repetitive message content portion located within the message after the displayable message content portion.

12. The method of claim 1, further comprising transmitting a command to the server to halt transmission of any further segments of the message if the message is determined to be encrypted.

13. The method of claim 1, further comprising transmitting a command to the server to transmit an entirety of the message received by the server to the mobile communications device at any time during the method of claim 1.

14. The method of claim 13, further comprising:

receiving the entirety of the message at the mobile communications device; and

verifying the message.

15. A system for receiving a message on a mobile communications device, the system comprising:

a processor configured to;

receive, at the mobile communications device from a message server via a transceiver, a first segment of the message, the first segment comprising at least a portion of a displayable message content portion comprised in a body of the message, said displayable message content portion being delimited within the body of the message by a predefined indicator identifying an end of the displayable message content portion;

scan the first segment for the predefined indicator;

automatically receive one or more further segments of the message at the mobile communications device and scan said one or more further segments of the message for the predefined indicator until the predefined indicator is found in a received segment; and

halt transmission of any further segments of the message once the predefined indicator is found.

16. The system of claim 15, wherein transmission of any further segments is halted by transmitting a command to the message server to halt said transmission.

17. The system of claim 15 wherein the message comprises a non-displayable message content portion located after the displayable message content portion.

18. The system of claim 15, wherein the delimiter comprises an identifier of a content format of the displayable message content portion.

19. A computer program product comprising a computer-readable medium storing executable program code executable by a processor of a mobile communications device, which, when executed, causes the mobile communications device to carry out the method of:

receiving, at the mobile communications device, a first segment of a message, the first segment comprising at least a portion of a displayable message content portion comprised in a body of the message, said displayable message content portion being delimited within the body of the message by a predefined indicator identifying an end of the displayable message content portion;

scanning, at the mobile communications device, the first segment for the predefined indicator;

automatically receiving one or more further segments of the message at the mobile communications device and scanning said one or more further segments of the message for the predefined indicator at the mobile communications device until the predefined indicator is found in a received segment.

20. A computer program product comprising a computer-readable medium storing executable program code executable by a processor of a mobile communications device, which, when executed, causes the mobile communications device to carry out the method of:

receiving, at the mobile communications device, a first segment of a message from a server, the first segment comprising at least a portion of a displayable message content portion comprised in a body of the message, said displayable message content portion being delimited within the body of the message by a predefined indicator identifying an end of the displayable message content portion;

scanning, at the mobile communications device, the first segment for the predefined indicator;

automatically receiving one or more further segments of the message at the mobile communications device from the server and scanning said one or more further segments of the message for the predefined indicator at the mobile communications device until the predefined indicator is found in a received segment; and

upon finding the predefined indicator transmitting a command to the server to halt transmission of any further segments of the message.

21. A computer program product comprising a computer-readable medium storing executable program code executable by a processor of a mobile communications device, which, when executed, causes the mobile communications device to carry out the method of:

receiving, at the mobile communications device, a first segment of a message from a server, the first segment comprising at least a portion of a displayable message content portion comprised in a body of the message, said displayable message content portion being delimited within the body of the message by a predefined indicator identifying an end of the displayable message content portion;

scanning, at the mobile communications device, the first segment for the predefined indicator;

automatically receiving one or more further segments of the message at the mobile communications device from the server and scanning said one or more further segments of the message for the predefined indicator at the mobile communications device until the predefined indicator is found in a received segment,

wherein said automatically receiving one or more further segments and said scanning said one or more further segments are carried out for a message not currently being viewed at the mobile communications device.
