Methods and apparatus to discover network capabilities available via wireless networks
First Claim
1. A method in a mobile device for network discovery, the method comprising:
- scanning for access networks;
performing Access Network Query Protocol (ANQP) queries to discover capabilities of the access networks prior to IEEE 802.11 association, wherein the capabilities of the access networks include at least one credential;
comparing the at least one credential with a second credential in one or more network capabilities profiles stored in the mobile device;
filtering out the access networks that do not match the second credential;
ranking the one or more network capabilities profiles; and
selecting an access network based on the ranking of the one or more network capabilities profiles.

Abstract
An example method for network selection involves discovering network capabilities by performing an Access Network Query Protocol (ANQP) query at a wireless terminal, and receiving a subsequent ANQP response from an access point of a wireless local area network. The network capabilities are indicated in the subsequent ANQP response. The example method also involves comparing the network capabilities with configured capabilities, finding a match between at least a portion of the network capabilities and at least a portion of the configured capabilities, and joining the wireless terminal with the access point based on the at least the portion of the network capabilities matching the at least the portion of the configured capabilities.
