Method and apparatus for automatic geoaware access point provisioning
Systems and methods of discovering and registering with a WiFi controller by a wireless access point that can provide location awareness in the WiFi controller discovery and registration process. The systems and methods employ a DNS server that can receive a DNS query containing the FQDN of a WiFi controller from an access point, and compare the FQDN of the WiFi controller and the source IP address of the DNS query against a mapping table, which maps FQDNs of WiFi controllers and ranges of source IP addresses of DNS queries to groups of WiFi controllers. By comparing the FQDN of the WiFi controller and the source IP address against the mapping table, the DNS server can resolve the FQDN to IP addresses of a group of WiFi controllers, which can belong to a particular broadband service provider, and/or serve a target market of mobile subscribers located within a geographical area.
