The embodiments of the present invention are further described in detail below in conjunction with the drawings and embodiments.

FIG. 1 is a flowchart of a method for controlling a policy of a data service according to an embodiment of the present invention, where the method includes:

Step 101: Acquire first policy information from a policy and charging rule network element, where the first policy information is based on a service, and the policy and charging execution network element determines execution execution decision policy information;

In this step, the UE and the Policy and Charging Enforcement (CPE) network element send a policy request to the Policy and Charging Rule Function (PCRF) network element through the Gx interface. The message request message may be a CCRI (credit control request-initial) message, but is not limited thereto; and receives a policy response message sent by the PCRF network element through the Gx interface, where The policy response message includes first policy information, and the first policy information includes at least one of the following: service detailed information, detailed service access information, and inter-policy dependency information. The policy response message may be a CCSI (credit control answer-initial) message, but is not limited thereto. Also applicable to, for example, credit control request (CCR, credit control request); credit control response (CCA, credit control answer); re-authorized request (RAR, Re-authorize request); or re-authorized response (RAA, Re -authorize answer ) and other messages.

The service detailed information may include: corresponding type information of the service; the access mode information of the service may include: a browser type used for the service access/a website type/error code/request for accessing the service Type / Multimedia Messaging Service ( MMS , Multimedia Messaging The service mode, the MMS content, the reliance policy name, and the like, and the information that is strongly related to the service and frequently changed. The inter-policy dependency information may include: a policy name to be relied upon, a policy execution result code, and the like.

Step 102: Acquire, when receiving the service request of the user, the service information required to match the first policy information in the service request; the service information may include a Uniform Resource Locator (URL) Information such as URL category, terminal type, and user agent.

After receiving the service request sent by the user, the PCEF network element performs a deep packet inspection (DPI, Deep Packet Inspection) on the service request to obtain a corresponding service content; and then, the service content is Performing an analysis to obtain service information required when the service request matches the first policy information. The service information may include: a URL, that is, a webpage address, or a category of a URL; and information such as a terminal type, a user agent, and the like, but is not limited thereto.

In addition, the service information of the service request may also include: querying the website classification corresponding to the URL according to the URL/IP/protocol, and the locally configured website classification policy; or obtaining the content in the response package. Type, such as text/card.

If the service request is an MMS request, the current request is an uplink request or a downlink request, and the information is obtained by parsing the request/response packet and obtaining the service information from the supporting network element.

Step 103: When the service information meets the first policy information, perform policy control on the service information according to the first policy information.

Optionally, the method may further include: determining whether the service information meets the first policy information, and if yes, performing policy control on the service information according to the first policy information; otherwise, activating the first The default policy is used to control the service information according to the activated first default policy. The policy information is controlled according to other effective policies.

The determining whether the service information meets the first policy information may be any one of the following three types of determining manners, and may be any two types, and may also be any three types, which are not limited in this embodiment. The three judgment methods are: The first type of judgment is to determine whether the service type of the service information meets the service detailed information in the first policy information, for example, whether the type of the service information accessed by the user is the service type included in the service detailed information in the first policy information. And if yes, performing policy control on the service information according to the first policy information;

The second method is to determine whether the access mode of the service information meets the access mode information of the service in the first policy information; for example, whether the browser type of the access service is the browsing in the access mode information of the service. a device type or the like; if yes, performing policy control on the service information according to the first policy information;

The third method is to determine whether the service information has inter-policy dependency information, that is, if there is inter-policy dependency information for the service information required by the local policy, the result of the PCEF selection line determines whether to execute the first policy. information. If the first policy information needs to be executed, the service information is controlled according to the first policy information.

In the embodiment of the present invention, the PCEF network element obtains the decision policy information (such as the policy information of the frequent service request or the policy information associated with the result of the frequent service request) based on the service and the PCF network element, so that the PCEF receives the information. After the service request of the user, the service information required to match the first policy information in the service request is obtained, and then, the service information is directly determined to satisfy the first policy information, and if the service information is satisfied, the service is The information is controlled according to the first policy information. The technical problem of the number of interactions between the PCRF network element and the PCEF network element is reduced in the policy control of the policy control or the result association of the frequently changed service request information in the prior art, and the performance overhead is reduced.

Optionally, on the basis of the foregoing embodiment, the method may further include: determining, when the service information required by the local policy corresponding to the received service request changes, determining whether the changed service information meets the current execution control policy If yes, the changed service information is continuously controlled according to the first policy information; otherwise, the current control policy is changed, and the second default policy is activated; and the changed service information is changed. Policy control is performed according to the second default policy. The first default policy and the second default policy may be the same or different, and the example is not limited. Wherein, an example of changing the current execution control policy and activating the changed default policy is: If the first policy is the business website is Yahoo (yahoo), and the website is free; and there is a priority ratio than the first strategy The low default policy is that all services are charged per KB of traffic. When the user's request is yahoo, the first policy is activated, and the default policy whose priority is lower than the first policy does not take effect on the current service flow, that is, the current service request is free, and when the next request content of the user is not yahoo, the first policy Invalid, it will change to the default policy execution, that is, charge by traffic.

In this embodiment, when the service information corresponding to the service request sent by the user changes, the PCEF network element does not need to send a policy request message to the PCRF network element for the changed service information, and only needs to determine the changed service information. Whether the first policy of the current execution control is met, if not, the second default policy is activated, and the changed service information is controlled according to the second default policy. Thereby, the number of interactions between the PCRF network element and the PCEF network element is reduced, and the performance overhead is reduced.

Optionally, when the decision policy information is changed, the method may further include: receiving, by the policy, a second policy information that is sent by the charging rule network element, where the second policy information is based on the service after the change, The policy and charging execution network element is required to determine the execution of the decision policy information. After the change is based on the service, the policy and the charging execution network element determine the execution of the decision policy information to add new policy information based on the first policy information. When receiving the subsequent service request of the user, performing policy control according to the second policy information.

In the embodiment of the present invention, when the PCRF network element receives the change of the user personalized setting, the decision policy information that changes the user personalized setting is sent to the PCEF network element, so that the PCEF network element needs to be updated in time to perform the judgment. Decision information. And when receiving the subsequent service request of the user, performing policy control according to the second policy information.

Charging-Rule-Install ::= < AVP Header: 1001 >

* [ Charging-Rule-Definition ]

* [ Charging-Rule-Name ]

* [ Charging-Rule-Base-Name ]

[ Bearer-Identifier ]

[ Rule-Activation- Time ]

[ Rule-Deactivation-Time ]

[ Resource-Allocation-Notification ] [ Charging-Correlation-Indicator ]

[PCEF-Rule-Filter]

[Filter-Logic]

[PS-Information]

* [Brower-Type]

* [Site-Category]

* [Content- Type]

* [MMS-Send-Type]

* [Protocol-ID]

[AVP]

[Rule-Chain-Information]

* [PCC-Rule-Satus]

* [Charging-Rule-Name]

[AVP]

*[ AVP ]

[Filter-Logic] , used to indicate whether the information processing is satisfied or not. The value can be 0: lnclude; l : Exclude. That is to say, it is judged whether the service information corresponding to the service request of the user satisfies the service-based decision information of the PCEF network element.

[PS-Information] AVP, access mode information for the service, the access mode information of the service may include: a browser type used for the service access/a website type of the access service/error code/request type/MMS transmission mode/ MMS content/dependent policy names and other information that are strongly related to the business and change frequently.

[Rule-Chain-Information], for transmitting inter-policy dependency information, the inter-policy dependency information includes: a policy name to be relied upon, a policy execution result code. When [Charging-Rule-Name] When not delivered, it means that for all policies, the current policy is executed when the specified error code occurs. It can be applied to the PCRF network element to deliver a unified default policy.

Step 606: The UE sends the service request of the user and the subsequent service request to the PCEF network element. Step 607: The PCEF network element acquires the service information required to match the first policy in the service request.

Step 608: The PCEF network element performs further decision on the service information corresponding to the service request according to the service policy that is sent by the PCRF network element, and needs the PCEF network element to perform the decision policy information, and executes the policy.

In this step, the PCEF network element first determines whether the service information required to match the first policy in the service request satisfies the first policy information, and the manner of the determination is three. For details, see the above. No longer.

That is, in step 607 and step 608, after receiving the service request, the PCEF network element determines, according to the received first policy information, a policy that requires further decision by the PCEF network element, and first obtains a need for further decision by the second obtaining unit. Business information, and then confirm whether to implement the policy.

It should be noted that, if the inter-policy dependency information is included in the first policy information, it is required to perform the policy after the execution based on the execution result of the dependent policy, that is, other dependent policies that are selected to execute the PCRF network element. After the execution, the policy is used to determine whether to execute the policy based on the policy result; the processing method of the PCEF network element for other dependent policies remains unchanged.

The next steps are optional steps:

Step 609: When receiving the service information corresponding to the user service request sent by the UE, the PCEF network element determines whether the changed service information meets the first policy information of the current execution control, and if yes, continues to change the service information. Performing policy control according to the first policy information; otherwise, changing a policy for currently performing control, activating a second default policy; and performing policy control on the changed service information according to a second default policy.

Step 610: The operation provider sends the user personalization setting change to the PCRF network element. Step 611: The PCRF network element sends the change policy information to the PCEF network element, and the additional condition of the change; the RAR message may be passed, but is not limited thereto.

That is, only when the PCEF network element decision information of the policy changes, the PCRF network element sends the policy information and the additional condition to the PCEF network element through the RAR message/CCA message, etc. The PCEF local policy decision information is changed, that is, the second policy information is sent, and the second policy information is based on the service after the change, and the policy and the charging execution network element are determined to execute the decision policy information, and the change is based on the service. The policy and charging execution network element needs to determine the execution of the decision policy information to add new policy information based on the first policy information. This embodiment takes an example of sending policy information and changing additional conditions by using RAR messages, as follows:

For example, in the Charging-Rule-Install field (AVP) of the RAR/CCAI message, add the following conditions to the change of the black part:

Charging-Rule-Install ::= < AVP Header: 1001 >

* [ Charging-Rule-Name ]

[PCEF-Rule-Filter]

[PS-Information]

[Brower-Type]

* [Site-Category]

[Content-Type]

[MMS-Send-Type]

[AVP]

[Rule-Chain-Information]

[PCC-Rule-Satus]

[Charging-Rule-Name]

[AVP]

*[ AVP ]

For the parental control class package set for the website type, when the user's custom information rule applies to the change of the website type setting, the PCRF network element can send the changed website type information to the PCEF network element through the RAR message.

Charging-Rule-Install ::= < AVP Header: 1001 >

* [ Charging-Rule-Name ]

[PCEF-Rule-Filter]

[PS-Information] [Brower-Type]

[Site-Category]

Step 612: The UE sends the user service request and the subsequent service request to the PCEF network element. Step 613: After the PCEF network element receives the received service request and the subsequent service request according to the received change policy information (ie, the second policy information), Policy control of this business request or subsequent business request.

In the embodiment of the present invention, an implementation scheme of a package based on complex data service information under the PCC framework is provided, which effectively reduces the performance overhead of the PCRF network element construction. For example, it is easy to implement policy control such as MMS complex MMS charging policy, URL category control policy, browser type and access content type. In addition, since the PCRF network element uniformly delivers the policy, it becomes a unified policy management center and avoids multiple strategies. The configuration is clear and the division of labor of the peripheral system is reduced, and the implementation difficulty is reduced. At the same time, the present invention also implements the dependency control between the policies, and reduces the performance overhead frequently generated by the policy report between the PCRF network element and the PCEF network element.

The following is a specific application example.

Embodiment 1

Suppose there is a strategy that needs to determine whether the content requested by the user is a file or a picture, the file is free, but the picture is billed.

When the PCRF network element sends a policy to the PCEF network element, the two policies can be directly delivered. The first policy is a file, which is free of charge. The second policy is the default policy, that is, the picture, and the charging. The block that is executed is: Charging-rule- Namel :==

RG:==Free RG

PCEF-Rule-Filter:==

Filter-Logic: include

Content-type := file

Charging-rule-name2 :==

Rg:==Billing RG

PCEF-Rule-Filter:==

Filter-Logic: include

Content-type : = image When the PCEF network element receives each request, it directly determines whether the content of the request is a file or a picture, and if it is a file, executes the first policy. If the image is a picture, the second policy is executed. When the content of the request is a picture, the content type of the request is reported to the PCRF network element, and the PCRF network element is received. After the reply, it can be determined whether the charging is free or not, therefore, the number of interactions between the PCRF network element and the PCEF network element is reduced.

Embodiment 2

Example 2: Suppose there is a parental control package, and the end user (ie, the parent) can set up the child's class that does not allow Internet access, such as social class. Later, you can also modify the categories that your child is allowed to access via the service provider portal (such as adding games, etc.).

When the child accesses the Internet, the PCRF network element directly sends the first policy to the PCEF network element. The first policy prohibits access to the social networking website: The program segment that it executes is:

Charging-rule-name 1 :==

Flow-status :==No access

PCEF-Rule-Filter:==

Filter-Logic: include

Site-gategory :=social

After receiving the child's access request, the PCEF network element directly determines whether it is accessing the social networking website. If yes, the access is prohibited. Instead of requesting the classification of each URL accessed by the child, the PCEF network element is re-reported to the PCRF network element to obtain whether The allowed access policy reduces the number of interactions between the PCRF network element and the PCEF network element.

Further, when the parent of the child can also add a non-accessible game class in the set classification by the portal, the PCRF network element can issue a new change policy (ie, the second policy) to the PCEF network element through the RAR message, and the second policy In order to prohibit access to social networking sites and game-like websites, the program blocks are:

Charging-rule-name 1 :==

Flow-status :==No access

PCEF-Rule-Filter:==

Filter-Logic: include

Site-gategory game Site-gategory social

After that, when receiving the child's subsequent request, the PCEF network element will simultaneously determine whether to access the game or social networking site, and if so, prohibit access.
