Interface selection in a wireless communication network
First Claim
1. A method comprising:
- assigning priorities to wireless network interfaces;
selecting one of the wireless network interfaces for access by an access terminal based on interface selection rules and the priorities; and
updating the priorities assigned to the wireless network interfaces based on status of the interfaces.

Abstract
This disclosure is directed to techniques for selection of wireless network interfaces for data communication within an access terminal. The techniques may rely on a set of interface selection rules to identify network interfaces that are eligible to serve a particular communication application or the type of traffic forwarded on behalf of another device. In addition, each network interface may be assigned a priority. Upon identifying eligible interfaces, e.g., interfaces that satisfy all of the interface selection rules, the techniques may involve selection of the eligible interface having the highest priority. The assigned priority may be dynamically adjusted based on the connection state of the interfaces, prioritization according to changes in system latency, interface cost, and the like.

- 11. An access terminal that assigns priorities to wireless network interfaces, selects one of the wireless network interfaces for access based on interface selection rules and the priorities, and updates the priorities assigned to the wireless network interfaces based on status of the interfaces.
- 21. A computer-readable medium comprising instructions that cause a processor to assign priorities to wireless network interfaces in an access terminal, select one of the wireless network interfaces for access based on interface selection rules and the priorities, and update the priorities assigned to the wireless network interfaces based on status of the interfaces.

31. A device comprising:
-
means for assigning priorities to wireless network interfaces;
means for selecting one of the wireless network interfaces for access by an access terminal based on interface selection rules and the priorities; and
means for updating the priorities assigned to the wireless network interfaces based on status of the interfaces.

32. A computer-readable medium comprising a data structure that defines a set of interface selection rules for selection of wireless network interfaces for access by an access terminal, wherein the interface selection rules are associated with each of the wireless network interfaces, the wireless network interfaces are assigned priorities, and the associations are arranged within the data structure in an order unrelated to the priorities assigned to the wireless network interfaces.

33. A method comprising:
-
assigning explicit priorities to rule classes in an access control list (ACL); and
selecting wireless network interfaces associated with the rule classes for access by an access terminal based on rules set forth in the ACL and the explicit priorities. - View Dependent Claims (34)
-
- 35. An access terminal that assigns explicit priorities to rule classes in an access control list (ACL), and selects wireless network interfaces associated with the rule classes for access by the access terminal based on rules set forth in the ACL and the explicit priorities.
- 37. A computer-readable medium comprising instructions to cause a processor within an access terminal to assign explicit priorities to rule classes in an access control list (ACL), and select wireless network interfaces associated with the rule classes for access by the access terminal based on rules set forth in the ACL and the explicit priorities.
-
39. A computer-readable medium comprising a data structure defining an access control list containing multiple rule classes for selection of wireless communication interfaces, and explicit priorities associated with the rule classes.
