A data service charging method, device and system

Abstract

The present invention provides a charging method for data services, which is applied in a communication network under a policy and charging control mechanism, comprising: the online charging system receives a session establishment request message sent by a gateway device, and the request message carries the gateway The device supports the indication information that the charging session granularity is IP-CAN Session; the online charging system processes the session establishment request message according to the charging session granularity is IP-CAN Session according to the indication information, and returns to The response message of the gateway device carries the indication information that the online charging system performs charging according to the IP-CAN Session granularity of the charging session, and the present invention can realize the situation that the OCS may support two charging session granularities at the same time In this case, the session granularity is negotiated when the charging session is established, and the charging session between the two is established according to the negotiated granularity, which improves the accuracy of charging.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data service charging method, device and system. Background technique [0002] PCC (Policy and Charging Control, strategy and charging control) is a set of policy and charging control mechanism defined by 3GPP (3rd Generation Partnership Project, third generation partnership project), its architecture is as follows figure 1 Shown: The architecture includes policy and charging enforcement function (PCEF device, Policy and ChargingEnforcement Function), traffic detection function (TDF, Traffic Detection Function), bearer binding and event reporting function (BBERF, Bearer Binding and Event Reporting Function ), policy and charging rule function (PCRF device, Policy and Charging Function), application function (AF, ApplicationFunction), online charging system (OCS, Online Charging System), offline charging system (OFCS, OfflineCharging System) and subscription Info...

Problems solved by technology

[0005] When the existing technology uses the Gy interface to transmit and process charging information, the charging session granularity of the Gy interface can be IP-CAN Session or IP-CAN Bearer. In actual deployment, it is likely that PCEF and OCS / OFCS support The granularity of the accounting session is different. Due to the difference in the collection mechanism of the accounting information, the reporting timing of the accounting information, or the collection of the accounting information under the two granularities, if the two parties cannot agree on the granularity of the accounting session, it will lead to billing. Processing errors or inaccurate billing
