Abstract

What is disclosed is a method of operating a wireless local area network (WLAN) access point. The method includes providing the WLAN for a user device to access a packet network, where the user device receives requested content transferred over the packet network through the WLAN access point. The method also includes receiving a message for delivery to the user device from a local interface of the WLAN access point, and in response to receiving the message for delivery to the user device, inhibiting transfer of the requested content received over the packet network to the user device. The method also includes transferring the message to the user device using addressing information associated with the requested content, and in response to receiving a confirmation of the message from the user device, resuming transfer of the requested content to the user device.

Claims

1. A method of operating a wireless local area network (WLAN) access point, the method comprising:

providing the WLAN for a user device to access a packet network, wherein the user device receives requested content transferred over the packet network through the WLAN access point;

receiving a message for delivery to the user device from a local interface of the WLAN access point;

in response to receiving the message for delivery to the user device, inhibiting transfer of the requested content received over the packet network to the user device;

transferring the message to the user device using addressing information associated with the requested content; and

in response to receiving a confirmation of the message from the user device, resuming transfer of the requested content to the user device.

2. The method of claim 1, further comprising:

processing the requested content to determine the addressing information associated with the requested content.

3. The method of claim 1, wherein the addressing information associated with the requested content comprises a header of a packet associated with the requested content.

4. The method of claim 1, wherein inhibiting transfer of the requested content received over the packet network to the user device comprises halting transfer of the requested content to the user device and buffering the requested content.

5. The method of claim 4, wherein resuming transfer of the requested content to the user device comprises transferring the buffered requested content to the user device.

6. The method of claim 1, wherein receiving the message for delivery to the user device from the local interface of the WLAN access point comprises receiving the message from a second user device communicating on the WLAN for delivery to the user device.

7. The method of claim 1, wherein transferring the message to the user device comprises processing the message and the requested content to determine alternate content for delivery to the user device, wherein the alternate content comprises the message in a data format of the requested content, and transferring the alternate content to the user device for display in an application on the user device expecting the requested content.

8. The method of claim 1, wherein providing the WLAN for the user device comprises establishing a first Internet protocol (IP) address for the user device through a first Dynamic Host Configuration Protocol (DHCP) process;

wherein inhibiting transfer of the requested content comprises establishing a second IP address for the user device through a second DHCP process;

wherein transferring the message to the user device comprises transferring the message using the second IP address; and

wherein resuming transfer of the requested content to the user device comprises re-establishing the first IP address for the user device and transferring the requested content to the user device using the first IP address.

9. The method of claim 1, wherein providing the WLAN for the user device to access the packet network comprises providing an IEEE 802.11 WLAN for the user device to access the WLAN access point, and establishing a wireless communication link between the WLAN access point and a cellular base station to provide access to the packet network for the IEEE 802.11WLAN.

10. A wireless local area network (WLAN) access point, comprising:

a WLAN interface configured to provide the WLAN for a user device to access a packet network, wherein the user device receives requested content transferred over the packet network through the WLAN access point;

a local interface of the WLAN access point configured to receive a message for delivery to the user device;

in response to receiving the message for delivery to the user device, the WLAN interface configured to inhibit transfer of the requested content received over the packet network to the user device;

the WLAN interface configured to transfer the message to the user device using addressing information associated with the requested content, and receive a confirmation of the message from the user device, and in response to the confirmation of the message, resume transfer of the requested content to the user device.

11. The WLAN access point of claim 10, further comprising:

a processing system configured to process the requested content to determine the addressing information associated with the requested content.

12. The WLAN access point of claim 10, wherein the addressing information associated with the requested content comprises a header of a packet associated with the requested content.

13. The WLAN access point of claim 10, wherein the WLAN interface is configured to halt transfer of the requested content to the user device and buffer the requested content to inhibit transfer of the requested content received over the packet network to the user device.

14. The WLAN access point of claim 13, wherein the WLAN interface is configured to transfer the buffered requested content to the user device to resume transfer of the requested content to the user device.

15. The WLAN access point of claim 10, wherein the local interface is configured to receive the message from a second user device communicating on the WLAN for delivery to the user device to receive the message for delivery to the user device.

16. The WLAN access point of claim 10, further comprising:

a processing system configured to process the message and the requested content to determine alternate content for delivery to the user device, wherein the alternate content comprises the message in a data format of the requested content; and

the WLAN interface configured to transfer the alternate content to the user device for display in an application on the user device expecting the requested content.

17. The WLAN access point of claim 10, wherein the WLAN interface is configured to establish a first Internet protocol (IP) address for the user device through a first Dynamic Host Configuration Protocol (DHCP) process to provide the WLAN for the user device;

wherein the WLAN interface is configured to establish a second IP address for the user device through a second DHCP process to halt transfer of the requested content;

wherein the WLAN interface is configured to transfer the message using the second IP address to transfer the message to the user device; and

wherein the WLAN interface is configured to re-establish the first IP address for the user device and transfer the requested content to the user device using the first IP address to resume transfer of the requested content to the user device.

18. The WLAN access point of claim 10, wherein the WLAN interface is configured to provide an IEEE 802.11 WLAN for the user device to access the WLAN access point, and

further comprising:

a cellular communication interface configured to establish a wireless communication link between the WLAN access point and a cellular base station to provide access to the packet network.

19. A method of operating a wireless local area network (WLAN) access point, the method comprising:

providing the WLAN for a user device to access a packet network, wherein the user device receives requested content transferred over the packet network through the WLAN access point;

processing device status of the WLAN access point to determine a message for delivery to the user device;

in response to determining the message for delivery to the user device, inhibiting transfer of the requested content received over the packet network to the user device;

transferring the message to the user device using addressing information associated with the requested content; and

in response to receiving a confirmation of the message from the user device, resuming transfer of the requested content to the user device.

20. The method of claim 19, wherein the device status comprises at least one of a battery status, a radio frequency (RF) signal strength, and a cellular roaming status, of the WLAN access point.
