Abstract

A system for managing information distribution to a mobile station in communication with a wireless network includes a host service operable to receive a data item associated with the mobile station and determine whether a network resource is associated with the mobile station, and upon a negative determination is further operable to transmit an out-of-band message to the mobile station to instruct the mobile station to acquire the network resource.

Claims

1. A method of distributing information from a host service in communication with a computer network to a mobile station in communication with a wireless network, the method comprising the steps of:

receiving a data item associated with the mobile station at the host service;

providing a network resource monitor in communication with the host service and the wireless network, the network resource monitor automatically providing network resource status information for the mobile station to the host service;

determining at the host service 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 transmitting resource request message from the host service to the mobile station to instruct the mobile station to acquire the network resource, wherein after the mobile station acquires the network resource, the network resource monitor automatically provides the network resource status of the mobile station to the host service; and

transmitting the data item to the mobile station using the network resource.

2. The method of claim 1, wherein the step of determining at the host service whether a network resource is associated with the mobile station comprises the steps of:

receiving a network resource status from the network resource monitor indicating network resources associated with the mobile station; and

determining from the network resource status if the network resource is currently associated with the mobile station.

3. The method of claim 1, wherein the step of transmitting band a resource request message from the host service to the mobile station to instinct the mobile station to acquire the network resource comprises the steps of:

transmitting a first instruction to cause the mobile station to acquire the network resource; and

transmitting a second instruction to cause the mobile station to transmit a confirmation message to the host service upon acquiring the network resource.

4. The method of claim 1, wherein the step of transmitting a resource request message from the host service to the mobile station to instruct the mobile station to acquire the network resource comprises the steps of:

transmitting an instruction to cause the mobile station to acquire the network resource; and

transmitting data indicating whether the mobile station is required to transmit a confirmation message tat the mobile station has acquired the network resource to the host service.

5. The method of claim 1, wherein the network resource is an Internet Protocol (IP) address.

6. The method of claim 1, wherein the network resource is a Packet Data Protocol (PDP) context.

7. The method of claim 1, wherein the resource request message is an SMS message transmitted from the host service to the mobile station over a wireless voice network.

8. The method of claim 1, further comprising the steps of:

the host service registering with the network resource monitor to receive automatic updates regarding the network resource status of the mobile station; and

storing registration data regarding the host service and the mobile station at the network resource monitor.

9. The method of claim 1, further comprising the steps of:

providing a plurality of host services in communication with a plurality of mobile stations;

each host service registering with the network resource monitor to receive automatic updates regarding network resource status of one or more of the plurality of mobile stations.

10. The method of claim 1, wherein the network resource monitor receives network resource status information for the mobile station from a Dynamic Host Configuration Protocol (DHCP) component of the wireless network.

11. The method of claim 1, wherein the network resource monitor receives network resource status information for the mobile station from a PDP Context Allocation component of the wireless network.
