Methods and apparatus to discover network capabilities available via wireless networks
First Claim
1. A method for selecting a network, the method comprising:
- determining network capabilities at a wireless terminal by;
scanning for wireless local area networks (WLANs); and
performing discovery Access Network Query Protocol (ANQP) exchanges to determine a list of network capabilities of access points of WLANs;
comparing the list of network capabilities with at least a portion of credentials;
finding a match between at least a portion of the list of network capabilities and at least the portion of the credentials;
filtering out the list of network capabilities that do not match at least the portion of the credentials; and
joining the wireless terminal with an access network associated with an access point of a WLAN based on the at least the portion of the list of network capabilities matching the at least the portion of the credentials.

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.
