Abstract
A system and method for a mobile data access network to make policy control and charging decisions based on domain name queries. A mobile device sends a query about a domain name associated with a service a user of the mobile device wishes to engage. The access network carries the domain name query from a mobile device to a domain name server. The access network detects the domain name query and copies the queried domain name. The access network uses the queried domain name to make an incomplete policy decision. The policy decision is incomplete because one or more service data flow filters in the decision lack addresses for providers of the service. The access network detects a response to the domain name query and copies a service provider address from the response. The access network uses the service provider address to complete the policy decision.
