Abstract

A method of managing data traffic offload from a radio access network may include: determining a location of a mobile device; and identifying, based on data traffic offload requirements of a network operator and capabilities of alternative network providers, one or more alternative networks configured to be accessed by the mobile device at the determined location.

Claims

1. A method of managing data traffic offload from a radio access network, the method comprising, by at least one hardware processor of a server:

obtaining an offload profile for at least one cellular sector in a cellular network, wherein the offload profile indicates a target traffic capacity for at least one time period; and

,

during the at least one time period, performing offload management based on the offload profile by

determining how much traffic capacity from alternative networks, different from the cellular network, is needed to satisfy the target traffic capacity for the at least one time period,

for each of one or more mobile devices within the cellular sector,

determining a location of the mobile device, and

identifying one or more alternative networks available to the mobile device at the determined location,

when more traffic capacity is determined to be needed from alternative networks, initiating an offloading of at least one of the one or more mobile devices to at least one of the one or more alternative networks available to that at least one mobile device, and,

when less traffic capacity is determined to be needed from alternative networks, initiating a disconnection of at least one of the one or more mobile devices from at least one of the one or more alternative networks available to that at least one mobile device.

2. The method of claim 1, wherein, for each of the one or more mobile devices, the one or more alternative networks available to the mobile device are identified based, at least in part, on at least one of a relative signal strength indication (RSSI), an encoding method selected by the mobile device, and an encoding method selected by an access point of at least one alternative network.

3. The method of claim 1, further comprising receiving an actual data usage on an alternative network from software applications executing on each mobile device that is offloaded to an alternative network.

4. The method of claim 1, wherein obtaining the offload profile comprises determining the target traffic capacity for the at least one time period based on actual traffic from a previous time period that precedes the at least one time period.

5. The method of claim 1, wherein the server is a cloud-based server.

6. The method of claim 1, wherein the method is performed for each of a plurality of cellular sectors in the cellular network.

7. The method of claim 1, wherein the offload profile indicates a target traffic capacity for each of a plurality of time periods, and wherein the offload management is performed for each of the plurality of time periods.

8. The method of claim 1, wherein the target traffic capacity comprises a data capacity.

9. The method of claim 1, wherein the target traffic capacity comprises a number of active mobile devices.

10. A system for managing data traffic offload from a radio access network, the system comprising:

at least one hardware processor; and

one or more software modules configured to, when executed by the at least one hardware processor,

obtain an offload profile for at least one cellular sector in a cellular network, wherein the offload profile indicates a target traffic capacity for at least one time period, and,

during the at least one time period,

determine how much traffic capacity from alternative networks, different from the cellular network, is needed to satisfy the target traffic capacity for the at least one time period,

for each of one or more mobile devices within the cellular sector,

determine a location of the mobile device, and

identify one or more alternative networks available to the mobile device at the determined location,

when more traffic capacity is determined to be needed from alternative networks, initiating an offloading of at least one of the one or more mobile devices to at least one of the one or more alternative networks available to that at least one mobile device, and,

when less traffic capacity is determined to be needed from alternative networks, initiating a disconnection of at least one of the one or more mobile devices from at least one of the one or more alternative networks available to that at least one mobile device.

11. The system of claim 10, wherein the one or more modules are further configured to, for each of the one or more mobile devices within the cellular sector, receive a result of a scan for available network access points around the location of the mobile device from the mobile device.

12. The system of claim 11, wherein, for each of the one or more mobile devices within the cellular sector, the identification of one or more alternative networks available to the mobile device is based, at least in part, on the result of the scan received from that mobile device.

13. The system of claim 12, wherein initiating an offloading of at least one mobile device to at least one alternative network available to that at least one mobile device comprises sending, via the cellular network, an identification of an access point of the at least one alternative network, to which the at least one mobile device should connect, to the at least one mobile device.

14. The system of claim 13, wherein sending an identification of an access point of the at least one alternative network to the at least one mobile device comprises sending a rank-ordered list of access points of a plurality of alternative networks available to the at least one mobile device.

15. The system of claim 10, further comprising a software application executing on each of the one or more mobile devices, wherein the software application is configured to, when executed by at least one hardware processor of a mobile device that has been offloaded to an alternative network:

monitor a quality of a signal of an access point for the alternative network to which the mobile device has been offloaded; and

in response to the quality decreasing below a threshold during a connection to the alternative network to which the mobile device has been offloaded, disconnect the mobile device from the access point, and connect to the cellular network.

16. The system of claim 10, wherein the one or more software modules are further configured to receive an actual data usage on an alternative network from software applications executing on each mobile device that is offloaded to an alternative network.
