Abstract

In one illustrative example, a mobile device receives from a relay services node an enable message which indicates a pending data message to be retrieved from a host service. The pending data message may comprise a body of text. Subsequent to the receiving of the enable message, a messaging application is opened at the mobile device. In response to the opening of the messaging application, the mobile device communicates directly with the host service without use of the relay services node, for retrieving the pending data message from the host service via a wireless network.

Claims

1. A method of operating a mobile device comprising:

receiving, at the mobile device from a relay services node, an enable message which indicates a pending data message to be retrieved from a host service, the pending data message comprising a body of text;

opening a messaging application at the mobile device subsequent to the receiving of the enable message; and

in response to the opening of the messaging application, communicating directly with the host service without use of the relay services node for retrieving the pending data message from the host service via a wireless network.

2. The method of claim 1, wherein the messaging application is an electronic mail (e-mail) application.

3. The method of claim 1, wherein the pending data message is an electronic mail (e-mail) message comprising the body of text.

4. The method of claim 1, wherein the enable message includes an identifier of the pending data message.

5. The method of claim 1, wherein the opening of the messaging application commences a data session.

6. A method of operating a mobile device comprising:

receiving, via a wireless network from a relay services node, an enable message which indicates a pending data message to be retrieved from a host service, the pending data message comprising a body of text;

opening a messaging application at the mobile device subsequent to the receiving of the enable message;

commencing a data session at the mobile device pursuant to the opening of the messaging application;

pursuant to the commencing of the data session, communicating directly with the host service without use of the relay services node for retrieving the pending data message from the host service via the wireless network, including;

sending, to the host service, a fetch message to retrieve the pending data message; and

receiving, from the host service, the data message in response to sending the fetch message.

7. The method of claim 6, wherein the wherein the pending data message is an electronic mail (e-mail) message comprising the body of text, and the messaging application comprises an e-mail application configured to receive the e-mail message comprising the body of text.

8. A method for communicating data messages comprising:

sending, from a relay services node, an enable message to a mobile device, the enable message being indicative of a data message received at a host service and destined for the mobile device, the data message comprising a body of text;

receiving via a wireless network the enable message at the mobile device;

opening a messaging application at the mobile device subsequent to receiving the enable message;

sending, from the mobile device to the host service, a fetch message to retrieve the data message responsive to the opening of the messaging application; and

in response to sending the fetch message, receiving from the host service the data message comprising the body of text.

9. The method of claim 8, wherein the messaging application is an electronic mail (e-mail) application.

10. The method of claim 8, wherein the data message is an electronic mail (e-mail) message comprising the body of text.

11. The method of claim 8, further comprising:

communicating directly with the host service without use of the relay services node for retrieving the data message from the host service via the wireless network.

12. The method of claim 8, wherein additional enable messages are only sent from the host service to the mobile device after the fetch message has been received by the host service.

13. The method of claim 8, further comprising:

opening a data session pursuant to the opening of the application; and

using the data session for the sending of the data message from the host service to the mobile device.
