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 mobile device, comprising:

a transceiver configured for wireless communications;

a memory;

a processor in operable communication with the transceiver and the memory, the processor being configured to;

receive, using the transceiver, 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;

scan the received first segment for the predefined indicator;

automatically receive, using the transceiver, one or more further segments of the message;

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

automatically transmit, using the transceiver, a command to halt transmission of any further segments of the message once the predefined indicator is found.

2. The mobile device of claim 1, wherein the processor is further configured to automatically transmit, prior to receipt of said one or more further segments, a command to transmit the further segments of the message.

3. The mobile device of claim 2, wherein said command to transmit the further segments is transmitted only if the predefined indicator has not yet been found.

4. The mobile device of claim 1, wherein the processor is configured to scan each further segment prior to receipt of a subsequent further segment.

5. The mobile device of claim 1, wherein at least a portion of the message is displayed at the mobile device while said scanning of the received first segment is carried out.

6. The mobile device of claim 1, wherein the message is not displayed at the mobile device while said scanning of the received first segment is carried out.

7. The mobile device of claim 1, wherein the displayable message content portion comprises one of plaintext, HTML, or RTF formatted content.

8. The mobile device of claim 1, wherein the delimiter comprises an identifier of a content format of the displayable message content portion.

9. The mobile device 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.

10. The mobile device of claim 1, wherein the processor is further configured to transmit, using the transceiver, a request for transmission of an entirety of the message.

11. A method, comprising:

receiving at a wireless communication device at least a first segment of a message, wherein the message comprises a plurality of portions of message content, each said portion being delimited by a predefined indicator, and said first segment comprises at least part of a first one of said plurality of portions of message content, said first one of the plurality of portions of message content comprising content displayable at the wireless communication device and being arranged in the message before other ones of the plurality of portions of message content;

if said first segment is determined to comprise an entirety of the first one of said plurality of portions of message content thus delimited, halting receipt of further segments of the message; and

if said first segment is determined not to comprise said entirety, continuing to receive further segments of the message at the wireless communication device until said entirety is determined to have been received at the wireless communication device.

12. The method of claim 11, further comprising scanning said first segment for the predefined indicator corresponding to said first one of the plurality of portions of message content to determine whether said first segment comprises said entirety.

13. The method of claim 11, wherein said halting receipt of further segments comprises transmitting a command to halt transmission of further segments to the wireless communication device.

14. The method of claim 11, wherein said content displayable at the wireless communication device comprises one of plaintext, HTML, or RTF formatted content.

15. The method of claim 11, further comprising determining from said first segment that the message is encrypted, and automatically requesting a remainder of the message for receipt at the wireless communication device.

16. A mobile device, comprising:

a transceiver configured for wireless communications;

a memory;

a processor in operable communication with the transceiver and the memory, the processor being configured to;

receive, using the transceiver, at least a first segment of a message, wherein the message comprises a plurality of portions of message content, each said portion being delimited by a predefined indicator, and said first segment comprises at least part of a first one of said plurality of portions of message content, said first one of the plurality of portions of message content comprising content displayable at the mobile device and being arranged in the message before other ones of the plurality of portions of message content;

if said first segment is determined to comprise an entirety of the first one of said plurality of portions of message content thus delimited, halt receipt of further segments of the message; and

if said first segment is determined not to comprise said entirety, continuing to receive, using the transceiver, further segments of the message until said entirety is determined to have been received.

17. The mobile device of claim 16, wherein the processor is further configured to scan said first segment for the predefined indicator corresponding to said first one of the plurality of portions of message content to determine whether said first segment comprises said entirety.

18. The mobile device of claim 16, wherein the processor is configured to halt said receipt by transmitting, using the transceiver, a command to halt transmission of further segments to the mobile device.

19. The mobile device of claim 16, wherein said content displayable at the mobile device comprises one of plaintext, HTML, or RTF formatted content.

20. The mobile device of claim 16, wherein the processor is further configured to determine from said first segment that the message is encrypted, and to automatically request, using the transceiver, a remainder of the message for receipt at the mobile device.

21. A method, comprising:

receiving at a wireless communication device at least a first segment of a message, wherein the message comprises a plurality of portions of message content, each said portion being delimited by a predefined indicator, and said first segment comprises at least part of a first one of said plurality of portions of message content, said first one of the plurality of portions of message content comprising content displayable at the wireless communication device, said content displayable at the wireless communication device comprising one of plaintext, HTML, or RTF formatted content;

if said first segment is determined to comprise an entirety of the first one of said plurality of portions of message content thus delimited, halting receipt of further segments of the message; and

if said first segment is determined not to comprise said entirety, continuing to receive further segments of the message at the wireless communication device until said entirety is determined to have been received at the wireless communication device.

22. A mobile device, comprising:

a transceiver configured for wireless communications;
