Abstract

The invention relates to a method for implementing strategies and the charging rule during the roaming and an implementing system thereof. The implementating method of the invention includes that: application function equipment sends an application / service request to roaming-place strategy function equipment; the roaming-place strategy function equipment obtains information of the strategies and the charging rule by exchanging with home strategy function equipment and then obtains confirmable information by exchanging the strategies and the charging rule with a gateway of the location where the roaming occurs. The implementing system comprises the home strategy and charging rule function equipment and a function and ordering information database in a home mobile network as well as a roaming-place strategy and charging rule function equipment, a roaming-place gateway and application function equipment in a roaming-place mobile network. The implementing method of the invention realizes the strategy control of the application function equipment in the location where the roaming occurs.

Description

technical field [0001] The invention relates to a method and a system for executing policies and charging rules in mobile communication, especially a method and system for executing policies and charging rules when roaming. Background technique [0002] Mobile network system policy and charging control PCC architecture (Policy and Charging Control architecture), including application function (Application Function, referred to as AF), policy and charging rules function (Policy and Charging Rules Function, referred to as PCRF), gateway (Gateway , GW for short), function and subscription profile repository (Subscription Profile Repository, SPR for short), in which the application function AF (such as P-CSCF in the IMS system) implements service control, and the policy and charging rule function PCRF is the policy control core, realizing According to the function of policy selection according to the service request, the gateway GW is the policy execution point, and completes th...
