Patent ID: 8185628

Claim:
A method for an access network to make a policy decision based on a domain name query comprising: detecting the domain name query for a domain name sent by a mobile device to a domain name server through an access gateway, the detecting of the domain name query being performed by a policy enforcement engine in the access gateway; sending a copy of the domain name copy to a policy server; making an incomplete policy decision based on the domain name; sending the incomplete policy decision from the policy server to the policy enforcement engine; detecting, by the policy enforcement engine, a domain name response sent from the domain name server to the mobile device through the access gateway, the domain name response including an address for a service provider associated with the domain name that is queried; completing the policy decision by using the address for the service provider to add service provider address information to the incomplete policy decision; and applying the policy decision to a service data flow between the mobile device and the service provider.
