Abstract

Wireless offloading provides tools to a service provider to encourage or direct a subscriber to offload from a first network, e.g., a cellular network, to a second network, e.g., a Wi-Fi network. The cellular service provider can use network data to determine wireless offloading priorities for cellular subscribers on an individual or group basis. The cellular service provider may use wireless network data it has and/or wireless network data it learns about networks from the wireless devices (which may obtain Wi-Fi network data from beacon frames of Wi-Fi networks or active scanning and which may report to the cellular service provider). Each wireless device can be given scanning assignments to ensure that the reporting task is shared among subscribers or adjusted to fill in gaps in data. With the network data, the cellular service provider is capable of generating useful prioritized network lists for wireless devices, either individually or as a group. Preferences can be encouraged in the form of incentive offers to subscribers to, e.g., offload from the cellular network to a Wi-Fi network. Incentive offers can include offers to lower service costs or provide additional or improved services.

Claims

1. A wireless end-user device comprising:

a radio configured to identify available wireless networks, the available wireless networks being different than a current wireless network to which the end user device is currently connected; and

a prioritized network selection engine configured to

select one of the available wireless networks based on a prioritized network list,

cause the wireless end-user device to connect through the selected available wireless network to a network element in a second network reachable through the selected available wireless network,

initiate an upload and/or download sequence between the wireless end-user device and the network element,

characterize performance of the selected available wireless network based on the conducted upload and/or download sequence, and

determine, based at least in part on the characterized performance, to communicate network data for the wireless end-user device through the selected available wireless network instead of the current wireless network.

2. The wireless end-user device of claim 1, configured to receive the prioritized network list from a remote server.

3. The wireless end-user device of claim 1, configured to supply information based on the characterized performance to an access network characterization server that collects such information from a plurality of wireless end-user devices.

4. The wireless end-user device of claim 1, wherein the prioritized network selection engine configured to cause the wireless end-user device to connect through the selected available wireless network comprises configured to automatically cause the wireless end-user device to connect through the selected available wireless network.

5. The wireless end-user device of claim 1, wherein the prioritized network selection engine configured to cause the wireless end-user device to connect through the selected available wireless network comprises configured to cause the wireless end-user device to connect through the selected available wireless network in response to a user selection.

6. The wireless end-user device of claim 1, wherein the prioritized network selection engine configured to cause the wireless end-user device to connect through the selected available wireless network comprises configured to automatically cause the wireless end-user device to connect through the selected available wireless network based on one or more user preferences.

7. The wireless end-user device of claim 1, the prioritized network selection engine further configured to provide a user of the wireless end-user device with a notification including an incentive offer to incent the user to connect to one of the available wireless networks.

8. The wireless end-user device of claim 7, wherein the incentive offer includes a network-performance incentive.

9. The wireless end-user device of claim 1, wherein the radio comprises a WiFi radio.

10. The wireless end-user device of claim 9, further comprising a cellular radio, and wherein at a time that the WiFi radio identifies available wireless networks, the current wireless network is a cellular wireless network.
