Enhanced policy capabilities for mobile data services
First Claim
1. A method for making a policy decision based on a domain name query, comprising:
- detecting, by a processor of a policy enforcement engine, the domain name query for a domain name sent by a mobile device to a domain name server;
sending, by the processor, a request to a policy server for making an incomplete policy decision based on the domain name;
detecting, by the processor, a domain name response sent from the domain name server to the mobile device, the domain name response including an address for a service provider associated with the domain name that is queried;
completing, by the processor, the policy decision by using the address for the service provider to add service provider address information to the incomplete policy decision; and
applying, by the processor, the policy decision to a service data flow between the mobile device and the service provider.

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.

7. A non-transitory computer-readable medium storing a plurality of instructions which, when executed by a processor of a policy enforcement engine, cause the processor to perform operations for making a policy decision based on a domain name query, the operations comprising:
-
detecting the domain name query for a domain name sent by a mobile device to a domain name server; sending a request to a policy server for making an incomplete policy decision based on the domain name; detecting a domain name response sent from the domain name server to the mobile device, 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. - View Dependent Claims (8, 9, 10, 11, 12)
