Abstract

A system and method for distributing information from a host service in communication with a computer network to a mobile station in communication with a wireless network is provided. A data item associated with the mobile station is received at the host service. The host service then determines whether a network resource of the wireless network is currently associated with the mobile station. If the network resource of the wireless network is not currently associated with the mobile station, then the host service transmits a resource request message to the mobile station to instruct the mobile station to acquire the network resource. Subsequently to acquiring the network resource, the host service is then able to transmit the data item to the mobile station using the network resource.

Claims

1. A method performed by a host service, comprising:

transmitting, to a mobile station over a wireless network, a resource request message that identifies a pending delivery to the mobile station of a data item, the resource request message including an instruction for the mobile station to acquire a network resource to enable delivery of the data item over the wireless network, the resource request message further including a portion of the data item to be displayed by the mobile station;

receiving, from the mobile station, a request for delivery of the data item, the request for delivery being responsive to acquisition by the mobile station of the network resource in response to the instruction; and

in response to the request, transmitting the data item to the mobile station using the network resource.

2. The method of claim 1 further comprising, before the transmitting of the resource request message:

determining by the host service that the network resource, required for transmission of the data item to the mobile station, is not currently associated with the mobile station.

3. The method of claim 1 wherein the resource request message is transmitted by the host service via an out-of-band channel.

4. The method of claim 3 wherein the out-of-band channel is through SMS.

5. The method of claim 1 wherein the portion of the data item is displayed by the mobile station to a user to enable the user to determine whether to receive a complete version of the data item from the host service.

6. The method of claim 1 wherein the transmitting includes transmitting an instruction for the mobile station to transmit a confirmation message to the host service upon acquiring the network resource.

7. The method of claim 1 further comprising:

receiving, from the mobile station, information identifying the network resource.

8. The method of claim 1 wherein the instruction includes a command to activate a PDP context.

9. The method of claim 1 further comprising, before the transmitting of the resource request message:

receiving the data item to be transmitted to the mobile station, the data item being addressed directly to the mobile station.

10. The method of claim 1 further comprising, before the transmitting of the resource request message:

receiving the data item to be transmitted to the mobile station, the data item being addressed to an electronic address at which data items are repeated to the mobile station.

11. The method of claim 1 wherein the transmitting of the resource request message is by pushing the resource request message to the mobile station.

12. The method of claim 1 wherein the receiving of the request for delivery from the mobile station is through HTTP communication.

13. The method of claim 1 wherein the resource request message contains a current cookie value, maintained by the host service for the mobile station, for the mobile station to include with the subsequent request for delivery of the data item.

14. A method performed by a host service, comprising:

transmitting, to a mobile station, a resource request message that identifies a pending delivery to the mobile station of a data item, the resource request message including an instruction for the mobile station to acquire a network resource to enable delivery of the data item over a wireless network, the resource request message further including a portion of the data item to be displayed by the mobile station;

receiving, from the mobile station, a request for delivery of the data item;

in response to the request, transmitting the data item to the mobile station using the network resource;

before the transmitting of the resource request message;

transmitting a delivery-pending message indicating delivery of the data item is pending;

tracking how much time has elapsed from when the delivery-pending message was transmitted; and

transmitting the data item to the mobile station in response to determining that the elapsed time is sufficient for the mobile station to have obtained the network resource.

15. The method of claim 14 further comprising:

receiving an error message in response to the transmitting of the data item in response to determining that the elapsed time is sufficient for the mobile station to have obtained the network resource; and

in response to receiving the error message, performing the transmitting of the resource request message to the mobile station.

16. A method performed by a mobile station, comprising:

receiving, from a host service, a resource request message that identifies a pending delivery to the mobile station of a data item, the resource request message including an instruction for the mobile station to acquire a network resource to enable delivery of the data item over a wireless network and further including a portion of the data item;

displaying the portion of the data item;

inquiring, through a user interface, whether the mobile station should acquire the network resource as instructed in the resource request message;

receiving, through the user interface, approval to acquire the network resource;

acquiring the network resource; and

in response to acquiring the network resource, sending, to the host service, a request for delivery of the data item.

17. The method of claim 16 wherein the resource request message is received from the host service via an out-of-band channel.

18. The method of claim 16 wherein the resource request message contains a current cookie value maintained by the host service for the mobile station, and the mobile station includes the cookie value with the request for delivery of the data item.

19. The method of claim 16, wherein the instruction includes a command to activate a PDP context.

20. A system comprising:

a computer; and

a service executable in the computer to;

transmit, to a mobile station over a wireless network, a resource request message that identifies a pending delivery to the mobile station of a data item, the resource request message including an instruction for the mobile station to acquire a network resource to enable delivery of the data item over the wireless network, the resource request message further including a portion of the data item to be displayed by the mobile station;

receive, from the mobile station, a request for delivery of the data item, the request for delivery being responsive to acquisition by the mobile station of the network resource in response to the instruction; and

in response to the request, transmit the data item to the mobile station using the network resource.

21. The system of claim 20, wherein the service is executable in the computer to further, before the transmitting of the resource request message:

transmit a delivery-pending message indicating delivery of the data item is pending;

track how much time has elapsed from when the delivery-pending message was transmitted; and

transmit the data item to the mobile station in response to determining that the elapsed time is sufficient for the mobile station to have obtained the network resource.
