Description

A method and system for determining policy rules

technical field

The invention relates to the processing technology of policy rules in the network, in particular to a method and system for determining policy rules.

Background technique

In different networks, how to determine and issue policy rules to the execution entity for execution, such as policy control and charging rules (PCC, Policy Control and Charging), or service quality (QoS, Quality of Service) policies or/and charging Regulations have become an urgent problem to be solved.

The latest Quality of Service (QoS, Quality of Service) framework of the Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for MicrowaveAccess) Network Working Group (NWG, Network Work Group) standard is shown in Figure 1. The mobile terminal (MS, Mobile Station) It is the mobile terminal of the user, and the user interacts with the network through the MS; the service flow management entity (SFM, Service Flow Manager) is used to establish the user service flow and allocate wireless resources for the established service flow, etc., and this functional entity exists in the ASN; The service flow authorization entity (SFA, Service FlowAuthorization) is used to authorize the service flow, and this functional entity exists in the ASN; the policy functional entity (PF, Policy Function, PF) is used to provide policies for the user's business flow, and the functional entity Provided by the Network Service Provider (NSP, Network Service Provider), when the user roams, there will be a visited PF (V-PF, Visited PF) and a home PF (H-PF, Home PF); the application function entity (AF, Application Function ) is a functional entity that provides application services. The user's MS directly accesses the AF through an application layer protocol connection, and the AF will notify the PF to actively create a service flow for the user. This functional entity is provided by the Network Service Provider (NSP).

The Internet Protocol Multimedia Subsystem (IMS, IP Multiedia Subsystem), as the core of the next-generation network "convergence", realizes the core network architecture of the establishment, maintenance and management of Internet Protocol (IP, Internet Protocol) multimedia services. Interworking based on IMS can be realized between heterogeneous networks. The main functions of the IMS architecture are:

Proxy Call Control Function (P-CSCF, Proxy-CSCF), which is the user's first contact point in the IMS system. The same operator's network may have one or more P-CSCFs. Its main functions are: based on the home network domain name (home network domain name) provided by the UE in the request, forward the UE's session initiation protocol registration (SIP REGISTER) request to the query CSCF (I-CSCF); after the user registers successfully, it can forward the user's SIP request and response messages to the serving CSCF (S-CSCF); send the charging information to the charging collection function (CCF, Charging Collection Function); perform media correction; check whether the media type and encoding format in the SIP session meet the requirements , whether the requirements of QOS can be satisfied, etc.; interact with the policy decision function (PDF, Policy DecisionFunction) through the Gq reference point, and transmit policy configuration information to realize media authorization; other functions, such as SIP message compression; protect SIP message integrity, Maintain security alliances with users, etc.

The PDF is responsible for formulating policies based on session and media-related information obtained from the P-CSCF, and it serves as a policy decision point controlled by Service Based Local Policy (SBLP). Its functions are: store session and media-related information; generate authorization tokens to identify PDF and sessions; when receiving bearer authorization requests from Internet Protocol-IP-CAN, provide authorization decisions based on stored session and media-related information ; When the session and media-related information is modified during the session change process, the corresponding authorization decision is updated; the ability to enable the authorized bearer; the ability to disable the authorized bearer but maintain the authorization; transmit an IMS charging identifier to the general gateway The Packet Radio Service Support Node (GGSN), and transmits a General Packet Radio Service (GPRS) Charging Identifier to the P-CSCF.

In the R1 phase of the WiMAX standard, only a preliminary description was made on the integration with IMS: in the WiMAX-IMS integration solution in the R1 phase, the WiMAX network is only used as an IP transmission network between the IMS client and the IMS network, and the original structure of the WiMAX network , The interface does not need to be changed to support the integration of this method.

The PCC framework is a problem mainly solved in Release 7 (R7) of 3GPP, and its purpose is the integration of Qos and billing. 3GPP has set up a special PCC topic group to study this problem. The current PCC architecture is a solution based on the fusion of the SBLP framework defined in R5 and the Flow Based Charging (FBC) framework defined in R6 in 3GPP. As shown in Figure 2: Among them, the PDF in SBLP and the CRF in FBC are fused into a policy control and charging rule functional entity (PCRF, Policy and Charging Rules Function), and both PDF and CRF are functional entities for rule formulation. Integrate the PEP in SBLP and the transmission plane function (TPF, TrafficPlane Function) in FBC into a policy control and charging enforcement function entity (PCEF, Policy and Charging Enforcement Function), namely the gateway (GW), PEP and TPF are both execution rules functional entities. In addition, the application function (AF, Application Function) still inherits the previous original function, that is, provides business information.

In addition, the Go and Gx interfaces are merged into Gx+, which provide charging rules and policy control rules to PEP/TPF respectively. The Gx interface supports policy control functions, called flow-based policy control (FBP), and PCC is oriented to the session layer and applications. The interfaces Gq and Rx of the layer are merged into Rx+. The Gq and Rx interfaces are very similar in function, and transmit the information about the IMS session and media parameters of the session control layer to the PCC. A Subscription Profile Repository (SPR, Subscription Profile Repository) functional entity is added to PCC, which is mainly an entity used to save real-time user subscription policies, and better maintain network and user policy consistency in PCC.

The PCRF includes the functions of the PDF in the SBLP and the CRF in the FBC, and provides QoS authorization information and charging rules to the GW. The input conditions for PCRF to formulate charging rules include three aspects of information: session and media-related information provided by AF; various information related to user subscription and network bearer provided by PCEF; configured on PCRF or provided by SPR and subscription, business-related information, etc. After receiving the service information of the AF, the PCRF may need to check whether the AF is allowed to transmit the information to the PCRF. PCRF is responsible for controlling the behavior of GW after receiving SDF, such as packet loss operation, which can be realized by issuing PCC rules. At the same time, the PCRF must also ensure that the traffic mapping and processing on the user plane of the GW are consistent with the subscription status of the user, which can be achieved by obtaining relevant information from the SPR. For GPRS, PCRF must be able to support policy control based on PDP context.

The PDF provides the authorized QoS to the GW, and then the GW compares the QoS with the QoS request of the UE, and then decides the follow-up operation. In the PCC, the GW provides the requested QoS to the PCRF, and the PCRF compares the requested QoS with the existing authorized QoS on the PCRF, and completes subsequent operations. That is to say, some functions of the original GW are moved up to the PCRF for execution. In PCC, PCRF is the control entity, and GW is only the execution entity.

In the PCC system, the GW includes the PEP of the SBLP and the TPF function of the FBC, and provides policy enforcement and charging rule enforcement for user plane traffic. In addition, the PCEF also has a feedback function, that is, it needs to feed back event messages that occur in the user plane to the PCRF. For an SDF under policy control, GW will let it pass only when the corresponding gate is in the open state. For an SDF under the control of the FBC, only if there is an active charging rule, the GW will let it pass. During the credit re-authentication process, the GW may also allow an SDF to pass.

Both policy control and charging control are implemented by executing the PCC rules delivered by the PCRF. The PCC rule may only carry policy control rules, may only include charging rules, or may include both policy rules and charging rules. This implementation mode is conducive to the smooth evolution from SBLP\FBC to PCC, and is also conducive to the wider applicability of PCC.

The WiMAX network and IMS convergence architecture formulated by the WiMAX network R1.5 version complies with the requirements of the PCC architecture.

Let’s take the WiMAX network as an example. In the WiMAX network, it is divided into ASN and CSN. The physical network elements in the ASN include BS and ASN-GW, and the AAA server and PCRF function body in the CSN. One ASN-GW is connected to multiple BSs and manages these BSs. In terms of Qos, SFM can be implemented on BS, while SFA or PCEF can be implemented on ASN-GW.

In a WiMAX network, GW is further divided into anchor GW and serving GW concepts, which are explained below:

When an MS switches between two ASN-GWs (the original ASN-GW is called the serving ASN-GW, and the new ASN-GW is called the target ASN-GW), the transfer of the user session is from the target ASN-GW to the CSN There will be two possible scenarios, as shown in scenario 1 and scenario 2 in FIG. 3 .

Scenario 1: An R4 data channel is established between the target ASN-GW and the anchor ASN-GW. User data is sent from the target ASN-GW to the anchor ASN-GW first, and then from the anchor ASN-GW to the CSN.

Scenario 2: The target ASN-GW re-anchors the user session as a new anchor ASN-GW, which is directly connected to the CSN.

These two scenarios will happen when the ASN-GW is switched. Generally, the user session will pass through the target ASN-GW to the anchor ASN-GW, and then from the anchor ASN-GW to the CSN. However, when the original anchor ASN-GW In some cases, it will actively ask the target ASN-GW to act as the new anchor ASN-GW, or when the target ASN-GW thinks that the anchor ASN-GW responds too slowly and resources are insufficient, it will actively ask the anchor ASN-GW Initiate a request to act as a new ASN-GW.

In order to clearly indicate that the same user in the ASN passes through multiple GWs, the ASN-GW that provides the R3 data channel and is connected to the core network is called R3GW, and the GW that is directly connected to the BS is called R6GW. In many scenarios, R3GW and R6GW is the same GW. With the movement of user terminals, after various handover scenarios occur, R3GW and R6GW may be two different GWs.

In a wireless network, BS and Cell are two basic concepts, which are introduced below:

BS is a wireless base station; Cell is a cell (or sector) under the base station. Multiple cells (or sectors) formed by configuring multiple carrier frequencies in a base station BS, that is, the coverage area of the BS can be Divided into multiple cells (or called sectors), of course, a base station can also have only one cell. When the MS moves, a handover between different cells of the same BS may be triggered, that is to say, there is a handover in which the BS remains unchanged but the Cell changes.

Diameter (Diameter) protocol is introduced as an AAA protocol supporting the AAA framework based on IP technology. The main functions of the Diameter protocol are: Authentication (Authentication) confirms the user's identity when the user uses the resources in the network system; Authorization (Authorization) the network system authorizes the user to use its resources in a specific way; Accounting (Accounting)) The network system collects , Record the use of network resources by users, so as to charge users for resource usage fees, or for auditing purposes. Taking the Internet access service provider ISP as an example, the user's network access usage can be accurately recorded according to traffic or time.

The Diameter message is composed of a message header and a message body. The message body is in units of AVPs. Each AVP carries a specific message parameter value. Each AVP includes an AVP header and a Data part. Among them, Event-Trigger AVP is an enumerated type. When this AVP is sent from PCRF to PCEF, it is used to indicate which events occur, and PCEF needs to re-apply for PCC rules. When this AVP is sent from PCEF to PCRF, it indicates the corresponding certain events occur.

The Diameter message includes a Credit Control Request (CCR) message and a Credit Control Response message (CCA), where the CCR message requests credit authorization for a business between the client and the credit control server; CCA is used between the credit control server and the client Acknowledge receipt of the CCR message.

From the above brief description, it can be seen that the 3GPP standards organization first proposed the PCC architecture. Since the PCC architecture conforms to the network development trend of QoS control and charging based on service flow, more and more standard-setting organizations introduce the PCC standard as their standard. Partly, the corresponding PCC architecture was originally formulated by 3GPP, and many features only conform to the 3GPP specifications. Therefore, various standard organizations that introduce the PCC architecture will make some improvements to the PCC architecture to adapt to their own network conditions.

However, currently there is no method for customizing different PCC rules according to MS access information in a network that integrates the PCC architecture. Furthermore, there is currently no method for determining policy rules based on MS access information.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

When the user accesses the network, the access information of the MS may include access network information, access area information or/and base station information.

Wherein, the access network information may be NAP, Access Network Code (Access Network Code) or other information that can identify the current access network.

The access area information may correspond to different information in different networks. For a WiMAX network, the access area information may be the access service network gateway IP (ASN-GW IP) address, service flow authorizer IP (SFA IP) address, Foreign agent IP (FA IP) address, data channel function body IP (DP Function IP) address, etc.; for GSM or code division multiple access (CDMA) network, access area information can be local area area identification (LAI, Location Area Identity ) or Routing Area Identity (RAI, Routing Area Identity), for a general IP network, the access area information can be an access server identification (NAS ID) or an access server IP address (NASIP address).

The base station information can be a base station identification code (BS ID), a cell identification code (Cell ID), a global cell identification code (CGI, Cell Global Identity), a BS IP address, or a service flow manager IP (SFM IP) address.

In the embodiment of the present invention, in a network integrating the PCC architecture, the PCEF reports the MS access information to the PCRE, and the PCRF can determine different PCC rules according to the MS access information, and deliver them to the PCEF for execution. In this way, different PCC rules can be determined according to the MS access information.

Fig. 4 is the flow chart of the method for determining PCC rules in the embodiment of the present invention, this method involves PCEF and PCRF in the PCC framework, and its specific steps are:

Step 401, PCEF sends a PCC rule request message to PCRF, and the message carries MS access information.

In the embodiment of the present invention, the PCC rule request message may be a CCR message or other messages, and the access information of the MS is one or more combinations of access area information, access network information and base station information.

Step 402: After receiving the request message, the PCRF determines the PCC rule according to the carried MS access information and other information in the existing mechanism.

Other information of the existing mechanism is service information from AF and user subscription information from SPR.

The policy for determining the PCC rule can be preset. For example, the direct correspondence between the MS's access information, some information of the existing mechanism, and each PCC rule is set in PCRF in advance, and the PCC rule is generated according to the correspondence. In the PCC rule, how to charge, how to charge Information about identifying charges and how to control billing.

In step 403, the PCRF sends a PCC rule response message to the PCEF, carrying the determined PCC rule.

The response message may be a CCA message or other messages.

Step 404: After receiving the response message, the PCEF executes the carried PCC rule.

In the embodiment of the present invention, if the WiMAX network introduces the PCC framework, the method for determining PCC rules is as shown in Figure 4, and if the WiMAX network follows its own standard planning, as shown in Figure 5, the involved network entities include SFA and PF, the network framework that can be referred to is shown in Figure 1, and its specific steps are:

Step 501, the SFA sends a request message to the PF, and the message carries the access information of the MS.

The request message may be a policy decision (Policy-Decision) message, a resource reservation (Resource-Reservation) message, a location update (Location-Update) message, a QoS policy request message, a charging rule request message, or a CCR message.

In step 502, the PF determines the QoS policy or/and charging rule according to the access information of the MS carried in the received request message and in combination with other information of the existing mechanism.

Policies for determining QoS policies or/and charging rules can be preset.

Other information of the existing mechanism may be service information from the AF, etc.

Step 503, the PF sends a response message to the SFA, carrying the determined QoS policy or/and charging rule.

Step 504: After receiving the response message, the SFA executes the carried QoS policy or/and charging rule.

The following specific examples are given to illustrate the methods provided in the embodiments of the present invention.

Embodiments 1 to 3 illustrate how to determine PCC rules according to MS access network information

Embodiment one

In the PCC architecture (including all PCC architectures such as WiMAX PCC, 3GPP PCC, 3GPP2 MMD, and TispanIMS), when MS accesses the network, IP-Connectivity Access Network (IP-CAN, IP-Connectivity Access Network) session establishment or PCEF conversion In this case, an application layer session needs to be established between PCEF and PCRF. Since the interface between PCEF and PCRF is a Gx interface in 3GPP, the session between PCEF and PCRF is called a Gx session. PCEF adds a Gx session establishment request message carrying The MS access network information, and the PCRF generates a PCC rule according to the MS access network information carried in the received message and combined with the existing information.

In 3GPP2, the interface between PCEF and PCRF is a Ty interface, so the session between them is called a Ty session. PCEF adds MS access network information to the Ty session establishment request message, and PCRF receives the MS The access network information is combined with existing information to generate PCC rules.

Fig. 6 is a flow chart of a method for determining PCC rules in a preferred embodiment of the present invention, and its specific steps are:

Steps 601 to 602, MS access network registration, IP-CAN session establishment or PCEF changes, PCEF will establish an application layer session with PCRF, and PCEF sends a CCR message to PCRF to request the establishment of an application layer session (Gx Session or Ty Session), the CCR message carries the access network information of the MS, and the access network information is NAP or Access Network Code.

Step 603: After receiving the CCR message, the PCRF generates a PCC rule according to some information of the existing mechanism and combined with the carried MS's access network information.

How to generate the PCC rule can be determined according to the set policy. For example: the corresponding relationship between the MS’s access network information, some information of the existing mechanism, and each PCC rule is set in the PCRF in advance, and the PCC rule is generated according to the corresponding relationship. In the PCC rule, there are how to charge, how to Identify the billing, and how to control the billing and other information.

In step 604, the PCRF returns a CCA message to the PCEF, and the message carries the PCC rule.

Step 605, the PCEF executes the PCC rule carried in the received CCA message.

Embodiment two

In the PCC architecture, when the MS accesses the network, the IP-CAN session is established, or the PCEF is changed, a Gx Session or Ty Session must be established between the PCEF and the PCRF. During the establishment of the Gx Session or Ty Session, the PCRF responds when the session is established. The message indicates that the PCEF should report the MS access network information change event. When the MS access network information changes when the MS moves and switches, the PCEF will report the MS access network information change event and the MS access network information at the same time. PCRF After the PCC rule is determined according to the reported MS access network information, the PCC rule is issued in the response message, and the PCEF executes the issued PCC rule. Figure 7 shows the second preferred embodiment of the present invention to issue and report the MS access network information change The method flow chart of the event, the specific steps are:

Step 701, when the MS accesses the network, the IP-CAN session is established or the PCEF is changed, the PCEF needs to establish a Gx Session or Ty Session with the PCRF, and the PCEF sends a CCR message to the PCRF, requesting the establishment of the Gx Session or Ty Session, CCR The message carries the access network information of the MS, and the access network information is NAP or Access Network Code.

Step 702, after the PCRF receives the CCR message, it generates a PCC rule based on some information of the existing mechanism combined with the carried MS's access network information, and the PCRF indicates in the PCC rule that the PCEF needs to report the MS's access network information change event, The PCRF returns a CCA message to the PCEF, and the message carries the PCC rule.

Fig. 8 is a flow chart of the method for reporting MS access network information change event in the second preferred embodiment of the present invention, and its specific steps are:

Step 801: When MS access network information changes due to MS movement, re-authentication process, or other circumstances, including but not limited to NAP or Access Network Code changes, PCEF reports access network information change events to PCRF through CCR messages . In addition to the existing content, the CCR message also carries the content shown in Table 1:

AVP AVP value Category Event-Trigger Add a value to the existing Event-Trigger AVP to indicate the access network information change event. It can be completed by increasing the value of Access_Network_Change during specific implementation. add new access network information The value of access network information is NAP or Access Network Code add new

Table I

That is, the CCR message carries the MS information change event identifier and the change value of the MS access network information.

Step 802: After receiving the CCR message, the PCRF regenerates the PCC rule according to some information of the existing mechanism and the carried modification value of the MS access network information.

In the embodiment of the present invention, the regenerated PCC rule may be different from the PCC rule already executed by the PCEF for the MS, and may also be the same. In the same case, it indicates that the change value of the MS access network information does not affect the PCC rule. At this time After the PCRF receives the MS access network information change event identifier, it does not necessarily deliver the regenerated PCC rule.

In step 803, the PCRF returns a CCA message to the PCEF, and the message carries the PCC rule.

Step 804: After receiving the CCA message, the PCEF executes the carried PCC rule.

Embodiment three

In the embodiment of the present invention, the WiMAX network adopts the PCC architecture when merging with the IMS network, as shown in FIG. It is a schematic diagram of the prior art.

As shown in the figure: the network includes SFM, SFA, agent (Agent), PCRF and AF connected in sequence. In this architecture, the WiMAX network introduces the Agent function body. The introduction of this function body is mainly to not change the Gx interface of the original PCC architecture. The Gx interface between PCEF and PCRF does not support mobility. During the IP-CAN session, both PCEF and PCRF will not move, and the Gx session between the two is always maintained. When the WiMAX network introduces the PCC framework, the PCEF is placed in the ASN-GW (SFA in the figure) entity for implementation. For the same MS, the ASN-GW will change as the MS moves. In order not to change the current It has PCC structure and adapts to the characteristics of WiMAX network, so the function body of Agent is proposed. The main function of this function body is to forward the Gx interface message and shield the change of SFA, that is, to shield the transformation of ASN-GW. There is a The interface is called R3 or R3-PCC interface. The difference from the Gx interface of the PCC framework is that the R3 or R3-PCC interface allows PCEF to change during an IP-CAN Session. Through the Agent, it can be realized that the existing Gx interface is used between the Agent and the PCRF. From the perspective of the PCRF, the Agent is a PCEF that does not move. At the same time, the R3 or R3-PCC interface is used between the Agent and the SFA. The SFA is essentially Entities that implement PCC rules, SFA can move and change. From a high-level point of view, SFA and Agent can be regarded as a PCEF, which fully complies with the original PCC framework.

On the basis of the architecture shown in Figure 9, in the process of establishing the R3 Session or R3-PCC Session between the SFA and the Agent and the Gx Session between the Agent and the PCRF, the CCR message carries the MS's access network information, and the method is as follows As shown in Figure 10:

Step 1001, the SFA sends a CCR message to the Agent, instructing the R3 Session or R3-PCCSession to be established, and the CCR message carries the access network information of the MS.

In the embodiment of the present invention, the SFA may also send other messages carrying the access network information of the MS to replace the CCR message, such as Policy-Decision message, Resource-Reservation message, Location-Update message, QoS policy request message, or Charging rule request messages, etc., only need to be bearer messages between the SFA and the Agent.

In the embodiment of the present invention, the content carried by the Diameter CCR message is shown in Table 2:

AVP The value of AVP Category Access to network information NAP or Access Network Code add new

Table II

Step 1002, after the Agent receives the CCR message, it judges whether it stores the user session information of the MS, such as Session-ID, if not, then executes step 1003;

If yes, then judge whether the MS access network information stored in the user session information of the MS is consistent with the MS access network information carried in the CCR message, if yes, perform step 1005; if not, perform step 1003.

Step 1003, the Agent sends a CCR message carrying the MS's access network information to the PCRF.

In the embodiment of the present invention, the content carried by the CCR message is shown in Table 3:

AVP The value of AVP Category Access to network information NAP or Access Network Code add new

Table three

Step 1004: After the PCRF receives the CCR message, it generates a PCC rule according to the carried MS's access network information and the information of the existing mechanism, and returns it to the Agent in the CCA message. The PCC rule carried in this message can indicate that it should be reported to the MS Access network information change events.

Step 1005, the Agent returns a CCA message to the SFA, and the message carries the PCC rule.

In the embodiment of the present invention, SFA can also send other messages carrying PCC rules to replace CCA messages, such as Policy-Decision message, Resource-Reservation message, Location-Update message, QoS policy request message, or charging rules Request messages, etc., only need to be bearer messages between the SFA and the Agent.
