Abstract

A router system receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes at least a first field having an identifier which identifies the mobile device, a second field having a payload of the message, and a third field having a return packet indication on whether to return a return packet to the host service. The router system examines the indication in the message and, if the indication is set to a first setting, the router system returns to the host service a return packet which indicates a status associated with the message for delivery to the mobile device. If the indication is set to a second setting, then the router system does not return to the host service the return packet which indicates the status associated with the message for delivery to the mobile device.

Claims

1. A method of operating a router system in a communication system which includes a host service, the router system, and a mobile device configured to operate in a wireless network which is connected to the router system, the method comprising:

receiving at the router system a message from a host service, the message being intended for delivery to the mobile device via the wireless network, the message including at least;

a first field which includes an identifier which identifies the mobile device;

a second field which includes a payload of the message;

a third field which includes a return packet indication on whether to return a return packet to the host service;

in response to receiving the message;

examining the return packet indication in the message;

if the return packet indication is set to a first setting, then returning to the host service a return packet which indicates a status associated with the message for delivery to the mobile device; and

if the return packet indication is set to a second setting, then not returning to the host service the return packet which indicates the status associated with the message for delivery to the mobile device.

2. The method of claim 1, further comprising:

delivering via the wireless network the message to the mobile device.

3. The method of claim 1, wherein the message further includes a fourth field comprising an identifier field associated with the message.

4. The method of claim 1, wherein the payload comprises data to be delivered on an application of the mobile device.

5. The method of claim 1, wherein the payload is for one of to an e-mail, an SMS message, an instant message, and Internet web browsing data.

6. The method of claim 1, wherein the router system is connected to the host service over the Internet.

7. The method of claim 1, wherein the status associated with the message indicates an availability or unavailability associated with the mobile device.

8. The method of claim 1, wherein the return packet includes the payload of the message.

9. The method of claim 1, wherein the host service comprises an e-mail server.

10. The method of claim 1, wherein the mobile device comprises a cellular telephone.

11. A computer program product, comprising:

a non-transitory computer readable medium;

computer instructions stored in the non-transitory computer readable medium;

the computer instructions being executable by a processor of a host service for operating a router system by;

receiving at the router system a message from a host service, the message being intended for delivery to a mobile device, the message including at least;

to a first field which includes an identifier which identifies the mobile device;

a second field which includes a payload of the message;

a third field which includes a return packet indication on whether to return a return packet to the host service;

in response to receiving the message;

examining the return packet indication in the message;

if the return packet indication is set to a first setting, then returning to the host service a return packet which indicates a status associated with the message for delivery to the mobile device; and

if the return packet indication is set to a second setting, then not returning to the host service the return packet which indicates the status associated with the message for delivery to the mobile device.

12. A router system configured for:

receiving a message from a host service, the message being intended for delivery to a mobile device via a wireless network, the message including at least;

a first field which includes an identifier which identifies the mobile device;

a second field which includes a payload of the message;

a third field which includes a return packet indication on whether to return a return packet to the host service;

in response to receiving the message;

examining the return packet indication in the message;

if the return packet indication is set to a first setting, then returning to the host service a return packet which indicates a status associated with the message for delivery to the mobile device; and

if the return packet indication is set to a second setting, then not returning to the host service the return packet which indicates the status associated with the message for delivery to the mobile device.

13. The router system of claim 12, which is further configured for:

delivering the message to the mobile device.

14. The router system of claim 12, wherein the message further includes a fourth field comprising an identifier field associated with the message.

15. The router system of claim 12, wherein the payload comprises data to be delivered on an application of the mobile device.

16. The router system of claim 12, wherein the payload is for one of an e-mail, an SMS message, an instant message, and Internet web browsing data.

17. The router system of claim 12, wherein the router system is connected to the host service over the Internet.

18. The router system of claim 12, wherein the status associated with the message indicates an availability or unavailability associated with the mobile device.

19. The router system of claim 12, wherein the return packet includes the payload of the message.

20. The router system of claim 12, wherein the host service comprises an e-mail server.
