Description

Policy operation method and system based on policy and charging control architecture

Technical Field

The invention relates to a policy operation technology, in particular to a policy operation method and a policy operation system based on a policy and charging control architecture.

Background

Policy and Charging Control (PCC) architecture is an architecture system proposed by the third Generation Partnership Project (3 GPP) organization after fusing Policy Control and flow-based Charging. A technical architecture for packet network Service data transmission Quality of Service (QoS) policy control and flow charging. The PCC architecture operates on a Service Data Flow (SDF) level, and provides functions such as policy control, charging control, and event reporting of Service Data flows. Specifically the device logic deployment is shown in fig. 1.

FIG. 1 is a schematic diagram of a PCC logic architecture in the prior art; as shown in fig. 1: the method comprises the following steps: a Policy and Charging Enforcement (PCEF) unit, a Policy and Charging Rule (PCRF) unit, an Application Function (AF) unit, an Online Charging System (OCS) unit, an Offline Charging System (OFCS) unit, and a user Policy Profile Repository (SPR); wherein the content of the first and second substances,

the functional entity of the PCEF unit is located at a packet domain gateway, for example: gateway GPRS Support Node (GGSN) for General Packet Radio Service (GPRS), PDN Gateway (P-GW, PDN Gateway) for Evolved Packet Core (EPC). The method mainly comprises the functions of deep message detection, strategy execution, charging based on the data flow and the like of the service data flow;

the functional entity of the PCRF unit has policy control decision and data flow charging based control, and provides the PCEF with functions of policy control based on traffic data flow, such as detection, gating, QoS based and data flow charging based.

The functional entity of the AF application functional unit is a service unit that provides an application, and is mainly used for performing dynamic policy and/or charging control on behaviors of an IP connection Access Network (IP-CAN) user plane and an application layer.

And the OCS unit is used for providing a real-time online charging control function based on the user and the service data flow.

And the OFCS unit is used for providing an offline charging control function based on the user and the service data flow.

The entity of the SPR unit contains information related to all strategy subscribers or strategy subscriptions. The SPR and PCRF network elements may be collocated or deployed independently.

Specifically, Rx in fig. 1 is a reference point between the AF and the PCRF. The Rx session function mainly implements an interaction function of application-level session information between the AF and the PCRF, such as: and the IP filter information is used for identifying the service data flow and carrying out policy control and charging on different service data flows. Media/application bandwidth requirements for QoS.

The function of the Rx session initiated by the AF contains an initial customization of the session information; modifying the session information; a gating process; the AF session is terminated; subscribe/unsubscribe signaling path state notification procedure.

The Rx session function initiated by the PRCF comprises service plane IP-CAN session termination; deactivating the service data flow, wherein the PCEF deactivation part causes the PCRF to initiate the process; a signaling path state notification process; an IP-CAN type change notification procedure; access network charging information notification procedure.

Gx is a reference point between the PCEF and the PCRF, and a PCC decision signaling is transmitted to implement a function of dynamically controlling a PCC behavior of the PCEF by the PCRF, which supports the following functions:

in the request of the PCC rule, the PCEF requests the PCC rule through the following flow of the Gx interface, an IP-CAN session initiated by the PCEF is established, and the IP-CAN session initiated by the PCEF is modified and is used for modifying the PCC rule requested by the PCEF.

In the customization of the PCC rules, the PCRF indicates the PCC rules to the PCEF through the following procedure of the Gx interface. The method is suitable for IP-CAN bearer-based, SDF-based, QCI-based authorized QoS customization and billing information customization. The PCRF can support the processing of two rules, namely a dynamic PCC rule and a predefined PCC rule;

IP-CAN session modification initiated by PCEF over Gx for PCC customization of PCEF requests. And the PCEF also initiates an indication procedure of event reporting and an indication procedure of IP-CAN session termination through Gx.

The PCRF modifies the IP-CAN session initiated by Gx, and the PCC customization process actively provided by the PCRF is applied to AF triggering or PCRF internal event triggering situations. And the PCRF initiates an IP-CAN session termination process through Gx. The method comprises the steps that a PCRF initiates an event-triggered customization process, and the customization process is carried out together with PCC rules as far as possible or independently;

in addition, Gx is also responsible for exception handling of PCC rules.

Sp is a reference point between SPR and PCRF. The PCRF requests information which is subscribed by the user and related to the IP-CAN transmission strategy from the SPR and inquires parameters based on the user ID, the PDN identification and the possible IP-CAN session. For example: the user's ID is the IMSI. When the subscription information of the user changes, if the PCRF subscribes to the notification, the SPR notifies the PCRF through the reference point. When receiving the request of canceling the notice from the PCRF, the SPR stops transmitting the updated user information.

Gy is a reference point between OCS and PCEF. For online reputation control when traffic-based data flow is being charged.

Gz is the reference point between PCEF and OFCS. For transferring offline charging information based on the traffic data stream.

Specifically, the solution of the PCC architecture is to use a PCEF/PCRF and other primary devices as a primary network element, and provide differentiated data services for a user based on a PS packet domain mobile network. The basis of the PCC solution is a policy, which is a specific rule for performing differentiated processing on users, and a service requirement determines the policy. The essence of PCC policy operation is that an operator performs end-to-end full-flow management on policy initiation and deployment, and a series of complete operation flows are deployed and executed on a main device after capability evaluation of the main device of a current network mobile network is performed by taking service requirements such as marketing or network quality assurance as initiation points and converting the requirements into a policy script language.

At present, a PCC policy operation mode of an operator has no fixed flow, but has a basically consistent operation idea, namely, a policy requirement is introduced through a service requirement, the policy requirement is converted into an equipment script language after analysis and evaluation, and effect evaluation after deployment and execution is issued.

One strategy deployment is a small project which has time requirements and effective expectations, but PCC strategy operation is a normalized and continuous work which is a behavior serving the strategic target of an enterprise, so that the strategy operation mode of the existing project type is changed and becomes urgent.

Since the PCC architecture in the prior art is all deployed on the network side, and the service support side does not have a corresponding device to acquire the operation information of the PCRF and the SPR device, the operation level cannot analyze and monitor the operation condition of the PCC related policy. Currently, an operator formulates a PCC policy by completing a series of processes in a conference, mail, telephone and other manners, and finally forming several different device policy scripts which are deployed on PCRF and PCEF network devices of multiple manufacturers. After the PCC policy is formulated, user information needs to be acquired from the service support side, and a PCC policy is signed on the SPR device for the user, and at present, a unified standard flow does not exist in the process. When the deployed PCC strategies reach a certain number, the strategy management is only to inquire records, and the operations of modifying, offline and the like of the corresponding PCC strategies can only be to delete corresponding scripts from each network element respectively. There is no unified evaluation method and tool for the evaluation process of the PCC policy after the policy is executed. Therefore, the PCC strategy scheme in the prior art has the following disadvantages:

(1) the flow is not uniform:

because the whole operation process can involve a plurality of departments, including headquarters departments and provincial companies, each department has own consideration and appeal, the phenomena of unclear responsibility and unsmooth communication can be caused, some departments want to be responsible for some processes, and some processes are not willing to be responsible for other processes, so that the operation process is seriously influenced.

(2) Policy conflict:

the strategy complexity is derived from various demands from various aspects such as users, networks, businesses, partners and the like, and relates to multi-department collaboration. With the increase of the demand, a multi-policy superposition phenomenon often occurs, policy conflicts gradually appear, and the conflicts are mainly expressed as that the user demand acting on a certain user conflicts with the network security policy, or the network security conflicts with the service demand policy, so that the final policy effect is greatly reduced, and the initial demand cannot be met finally. The service requirement is the premise of forming the strategy, and effective requirement management is the basis for the PCC strategy to play a role and is an important means for preventing strategy conflict.

(3) Scattered management of multi-vendor script protocols:

the functional units used by PCC are a policy and charging rule function PCRF and a policy and charging enforcement function PCEF, both of which have multiple vendors, and need to configure scripts of multiple vendors respectively when deploying the same service, without performing unified management on the scripts.

(4) The evaluation of the effect is difficult:

after the PCC related services are deployed, the effect of the services needs to be evaluated, currently, only the index parameters of the service support side are screened from platforms such as a service support system and the like to be calculated and generate a report, so that index acquisition of the network side is lost, and no uniform effect evaluation index exists;

(5) the management of the PCC service life management cycle is difficult:

PCC related services are dispersed in a plurality of functional units, unified management is not carried out, and unified entry tools are not provided when strategies are deployed, modified, offline and service life cycle management.

The system manages the PCRF scripting languages of a plurality of operation sides in a centralized manner for the convenience of policy operation execution, forms a uniform scripting interface according to different PCRF scripting language protocols of each operation side, and issues the scripting language to the PCRF of each operation side through the uniform scripting interface.

The specific implementation principle is that PCRF script protocols of each operation side are submitted on the system, the PCRF script protocols are managed by the system in a centralized manner, then interfaces are connected with PCRFs of each operation side, SOAP command protocols and information such as directories, user names, login passwords and file names of the system storage scripts are transmitted to PCRFs of each operation side through unified script interfaces, and after receiving the commands, the PCRFs of each operation side download the scripts under the directories by ftp and automatically load the scripts on PCRF equipment of each operation side to execute the strategies.

Step 203, sending the user subscription information to the PCRF and/or the SPR, and performing a subscription operation of a PCC policy on a target client through the PCRF and/or the SPR based on the scripting language and the user subscription information.

Here, the business analysis platform in the system sends the user subscription information to the BOSS unit in the system, the BOSS unit sends the user subscription information to the PCRF of each operation side, and the PCRF performs a subscription operation of the PCC policy on the target client according to the user subscription information after receiving the user subscription information. When the target client accesses the internet, the PCRF and the operation analysis platform collect behavior information and subscription information of the user in real time, the PCRF and the operation analysis platform report the behavior information and the subscription information of the user to each sub-node as effect evaluation information, and then each sub-node sends the effect evaluation information to the centralized node.
