Problems solved by technology

[0008] With the needs of operators, network integration and the development of multiple access technologies, multiple gateways (GW, Gateway) gradually appear in the network, and there are multiple message transfer interfaces with OCS, which are used to report billing information to OCS and receive OCS notification, so that it is impossible to complete the accounting and reporting of all users’ charging information through one GW as before, which will lead to the problems of inconsistent charging granularity, methods and performance, and the problem of OCS multipoint communication selection. To a certain extent, it will affect the uniformity and stability of billing
On the other hand, in the network where the PCC architecture is introduced, the PCRF entity completes the policy and charging rule functions of the entire network in a unified manner, and each GW in the network has a standardized interface, and the existing charging information is sent by the GW to the accounting billing system (including online and offline billing systems), increasing the signaling burden of bearer equipment
[0009] In the prior art, there is still no solution for how to realize the unification of billing method and performance in a network of multiple GWs

Embodiment 1

[0066] The PCC rule is online charging, and the PCRF entity sends a request message to the OCS. When the UE initiates a certain service, after generating the PCC rule, it is judged whether the PCC rule is online charging, and if so, when the PCRF entity is triggered by an external or internal credit quota application, the PCRF entity sends the message to the OCS through the first interface A request message for credit quota application, OCS returns a response message to the PCRF entity after receiving the request message (delivering the usage quota); during the business process, the PCRF entity receives an external or internal credit quota application trigger again, and sends an application credit request message to OCS Quota request message, and report the billing-related information such as actual usage to OCS, and receive the response message from OCS; when the service ends, the PCRF entity sends a request message to OCS (report the current usage and bring all the informatio...

Embodiment 2

[0079] The PCC rule is offline charging, and the PCRF entity sends a message to OFCS. The UE initiates a certain service and after generating the PCC rule, judges whether the current charging rule is offline charging. If the charging reporting trigger condition is met during the service process, the PCRF entity will receive an internal or external reporting trigger. Send a message to the OFCS through the second interface (report charging-related information such as current usage), and receive a response from the OFCS. Billing reporting trigger conditions may include: traffic threshold, time threshold, hour, rate change, update (location update, access type update, time zone update, relevant IP-CAN session modification, etc.), service end, etc. The above billing process specifically includes the following steps:

[0080] Step 501: UE initiates a certain service, and after PCC rules are generated, it determines that the current service is offline charging, and then initiates an...

Embodiment 3

[0088] For online charging, the OCS actively sends a notification to the PCRF entity (requiring usage report, re-authentication, etc.), and the PCRF entity sends a response message to the OCS (according to the request in the notification message, report accordingly). When the UE initiates a service and the PCC rule is generated, if the PCC rule is online charging, when the PCRF entity is triggered by an external or internal credit quota application, the PCRF entity actively sends an application for credit quota to the OCS through the first interface After receiving the request message, the OCS returns a response message to the PCRF entity (delivering the usage quota); during the business process, the OCS actively sends a notification message to the PCRF entity, requesting to report the usage amount or re-authenticate, and the PCRF entity receives After the message is notified, corresponding processing is performed, and a response message is sent to the PCRF entity to inform the...

Abstract

The invention discloses a policy and charging control (PCC) framework-based charging method. The method comprises the following steps of: arranging an interface between a policy and charging rule function (PCRF) entity and an online charging system (OCS), wherein the PCRF entity reports information used for charging to the OCS through the interface and receives the response of the OCS, and the OCS actively sends a notice used for charging to the PCRF entity through the interface and receives the response of the PCRF entity; or arranging an interface for information interaction between the PCRF entity and an offline charging system (OFCS), wherein the PCRF entity sends the information used for charging to the OFCS through the interface. The invention discloses a system for implementing the method at the same time. By the method and the system, user terminals under each gateway can realize charging operation with various granularities, various PCC frameworks and improved structures thereof are supported, and the technical scheme is simple and practical.

Description

technical field [0001] The present invention relates to policy and charging control (PCC, Policy and Charging Control) technology, in particular to a charging method and system based on a policy and charging control framework. Background technique [0002] The Evolved Packet System (EPS, Evolved Packet System) of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is composed of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (S-GW, ServingGateway), Packet Data Network Gateway (P-GW or PDN GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), 3GPP It consists of authentication, authorization and accounting (AAA, Authentication, Authorization and Accounting) server, policy and charging rules function (PCRF entity, Policy and Charging Rules Function) entity and other s...
