Description

The manner of execution and the system of strategy and charging regulation during roaming

Technical field

The present invention relates to the method and system of implementation strategy and charging regulation in the mobile communication, the manner of execution and the system of strategy and charging regulation during particularly a kind of the roaming.

Background technology

In mobile network system strategy and the charging control PCC framework (Policy and Charging Control framework), comprise application function (Application Function, be called for short AF), "Policy and Charging Rules Function (Policy and Charging Rules Function, be called for short PCRF), gateway (Gateway, be called for short GW), function and purchase order information storehouse (Subscription Profile Repository, be called for short SPR), wherein application function AF (as the P-CSCF in the IMS system) realizes professional control, "Policy and Charging Rules Function PCRF is the policy control core, realization is according to the function of service request selection strategy, gateway GW is a Policy Enforcement Point, finishing Business Stream surveys, strategy execution and based on stream functions such as charging, deposit user or the purchase order information that is used for policy control among function and the purchase order information storehouse SPR.

In said system, the interface between application function AF and the "Policy and Charging Rules Function PCRF is a Rx interface, is used for the relevant information to "Policy and Charging Rules Function PCRF transport service from application function AF, as IP five-tuple and qos parameter.Interface between "Policy and Charging Rules Function PCRF and the gateway GW is the Gx interface, be used for "Policy and Charging Rules Function PCRF and send concrete strategy and charging regulation, and gateway GW returns the execution result of dependency rule to "Policy and Charging Rules Function PCRF to gateway GW.Interface between "Policy and Charging Rules Function PCRF and function and the purchase order information storehouse SPR is the Sp interface, be used for "Policy and Charging Rules Function PCRF and send user or purchase order information request, and function and purchase order information storehouse SPR send user or purchase order information to "Policy and Charging Rules Function PCRF to function and purchase order information storehouse SPR.

Its workflow is: whether application function AF inserts this business to the QoS information that "Policy and Charging Rules Function PCRF sends application/business by "Policy and Charging Rules Function PCRF decision; If "Policy and Charging Rules Function PCRF decision inserts this business, then "Policy and Charging Rules Function PCRF sends policing rule to gateway GW; Gateway GW is after carrying out this rule, and PCRF returns policy execution result to "Policy and Charging Rules Function; Whether last "Policy and Charging Rules Function PCRF can insert this business to application function AF report.

The network configuration of the scheme of PCC framework roaming at present comprises roaming place mobile network and ownership place mobile network, the roaming place mobile network comprises roaming place "Policy and Charging Rules Function (Visited Policy andCharging Rules Function, be called for short V-PCRF) and roaming place gateway (Visited Gateway, be called for short V-GW), the ownership place mobile network comprises ownership place "Policy and Charging Rules Function (Home Policy andCharging Rules Function, be called for short H-PCRF) and function and purchase order information storehouse (SubscriptionProfile Repository, be called for short SPR), application function (Application Function is called for short AF) is at ownership place.The implementing procedure of its policy control is specially:

Step 1, application function AF send application/business information to ownership place "Policy and Charging Rules Function H-PCRF;

Step 2, ownership place "Policy and Charging Rules Function H-PCRF send the request of user's ordering information to function and purchase order information storehouse SPR;

Step 3, ownership place "Policy and Charging Rules Function H-PCRF judge whether to insert this business after receiving user's ordering information response that function and purchase order information storehouse SPR return;

If step 4 decision inserts this business, ownership place "Policy and Charging Rules Function H-PCRF sends strategy and charging regulation to roaming place "Policy and Charging Rules Function V-PCRF;

Step 5, roaming place "Policy and Charging Rules Function V-PCRF send strategy and charging regulation to roaming place gateway V-GW;

Behind step 6, the roaming place gateway V-GW executing rule, return strategy and charging execution result to roaming place "Policy and Charging Rules Function V-PCRF;

Step 7, roaming place "Policy and Charging Rules Function V-PCRF send to the ownership place "Policy and Charging Rules Function with strategy and charging execution result;

Whether step 8, ownership place "Policy and Charging Rules Function H-PCRF can insert this business to application function AF report.

This shows that above-mentioned implementation method has only been considered the situation of application function AF at ownership place.For the partial service control system, as the IMS system, above-mentioned implementation method can not realize the policy control during in the roaming place as application function AF.

Summary of the invention
