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 in a wireless user terminal for selecting a network access point for offloading network traffic from a first network to a second network, wherein network access information is need to connect to the second network through the network access point, the method comprising:

determining a measure of frequency during which the wireless user terminal discovers that the network access point is within range;

determining whether the measure of frequency exceeds a predefined threshold;

if the measure of frequency exceeds the predefined threshold, obtaining at least one piece of information identifying an operator of the network access point;

searching a contacts list in the wireless user terminal for the at least one piece of information identifying an operator of the network access point; and

if the at least one piece of information identifying an operator of the network access point is found the contacts list, sending a request for network access information to an operator of the network access point.

2. The method according to claim 1 wherein the operator of the network access point is associated with an operator terminal, the method further comprising determining whether the wireless user terminal has communicated with the operator terminal.

3. The method according to claim 2 where determining whether the wireless user terminal has communicated with the operator terminal includes searching a call history log in the wireless user terminal for an identifier associated with the network access point operator.

4. The method according to claim 2 where determining whether the wireless user terminal has communicated with the operator terminal includes searching an SMS history log in the wireless user terminal for an identifier associated with the network access point operator.

5. The method according to claim 2 where determining whether the wireless user terminal has communicated with the operator terminal includes searching an email log in the wireless user terminal for an identifier associated with the network access point operator.

6. The method according to claim 2 wherein, if it is determined that the wireless user terminal has communicated with the operator terminal, sending a request for network access information to an operator of the network access point.

7. The method according to claim 1 further comprising computing a first relationship coefficient as a function of the measure of frequency;

comparing the first relationship coefficient to a predefined threshold; and

sending a request for network access information to an operator of the network access point if the first relationship coefficient is equal or greater than the predefined threshold.

8. The method according to claim 7 further comprising determining a second relationship coefficient as a function whether the at least one piece of information identifying an operator of the network access point is found the contacts list;

and

sending a request for network access information to an operator of the network access point if the second relationship coefficient is equal or greater than the predefined threshold.

9. The method according to claim 8 further comprising determining a third relationship coefficient as a function whether the at least one piece of information identifying an operator of the network access point is found the call history;

and

sending a request for network access information to an operator of the network access point if the third relationship coefficient is equal or greater than the predefined threshold.

10. The method according to claim 9 further comprising determining a fourth relationship coefficient as a function whether the at least one piece of information identifying an operator of the network access point is found the SMS log;

and

sending a request for network access information to an operator of the network access point if the fourth relationship coefficient is equal or greater than the predefined threshold.
