Abstract

The present invention is directed to a method and system for selecting a wireless network for offloading network traffic from another network. In one embodiment, a method and system for offloading network traffic in a wireless user terminal from a first network, such as cellular network, onto a second network, such as a WiFi network, includes determining a measure of the relationship between the user of the wireless user terminal and the owner of the access point for the second network. The measure of the relationship can be used to provide an indication of the likelihood that the owner of the access point will grant access to the user of the wireless user terminal.

Claims

1. A method for obtaining access to a network using a wireless device, wherein network access information is needed to connect to the network through a network access point, the method comprising the following operations performed on one or more processors:

determining a measure reflecting a likelihood that an owner or operator of the network access point will grant the device access to the network;

searching a database for information identifying an owner or operator of the network access point as a function of whether the measure exceeds a threshold; and

sending a request for the network access information to a terminal associated with the owner or operator of the network access point based on the searching.

2. The method of claim 1, wherein searching the database further comprises:

providing information identifying the network access point to a server having access to the database; and

receiving the information identifying the owner or operator of the network access point from the server.

3. The method of claim 1, further comprising:

receiving the network access information from the terminal associated with the owner or operator of the network access point; and

establishing a connection to the network using the network access information.

4. The method of claim 3, wherein the database includes at least one of an external database or a contacts list in the device.

5. The method of claim 4, further comprising determining whether the device has communicated with the terminal by one or more of:

searching a call history log in the device for an identifier associated with the owner or operator of the network access point;

searching an SMS text history log in the device for an identifier associated with the owner or operator of the network access point;

or

searching an e-mail log in the device for an identifier associated with the owner or operator of the network access point;

searching an internet usage history of the device for an identifier associated with the owner or operator of the network access point;

searching a list of locations visited by the device for an identifier associated with the owner or operator of the network access point searching applications used by the device for an identifier associated with the owner or operator of the network access point; and

wherein sending the request for the network access information occurs in response to finding the identifier associated with the owner or operator of the network access point in the database.

6. The method of claim of 1, wherein the measure is based on a set of coefficients reflecting a degree of relationship an owner or operator of the device has with the owner or operator of the network access point, and wherein the set of coefficients includes a first coefficient reflecting a frequency of a number of times the device is within range of the network access point during a set of time periods.

7. The method of claim 6, wherein the set of coefficients further includes at least two of:

a second coefficient reflecting whether the network access point is public or private;

a third coefficient reflecting an average received signal strength indication associated with network access point during the set of time periods;

a fourth coefficient reflecting whether the identifying information is found in one of a call history, a text message history, or e-mail history log in the device;

a fifth coefficient reflecting whether the identifying information is found in a contacts list in the device;

a sixth coefficient reflecting whether information identifying the owner or operator of the device is found in one of a call history, a text message history, or e-mail history log in the terminal associated with the owner or operator of the network access point;

or

a seventh coefficient reflecting a duration of time the device is within range of the network access point.

8. The method of claim 7, wherein the set of coefficients includes the fourth coefficient, and wherein the fourth coefficient is further based on a frequency of communication between the device and the terminal specified in the one of the call history, the text message history, or the e-mail history.

9. The method of claim 7, further comprising:

updating a coefficient in the set of coefficients based on a change to the degree of relationship between the owner or operator of the device and the owner or operator of the access point; and

updating the measure based on the updated coefficient.

10. The method of claim 7, wherein a coefficient in the set of coefficients is subjected to an aging measure reducing a value of the coefficient when the coefficient has not increased over a period of time.

11. The method of claim 7, wherein sending the request for the network access information occurs when a measure associated with the set of coefficients exceeds a measure associated with a set of thresholds, and wherein:

the measure associated with the set of coefficients comprises a weighted average of at least three coefficients in the set of coefficients;

or

the measure associated with the set of thresholds comprises a respective threshold for at least three coefficients in the set of coefficients.

12. A system for obtaining access to a network using a wireless device, wherein network access information is needed to connect to the network through a network access point, the system comprising:
