[PS-Information] AVP, for the access mode information of business, the Type of website/error code/request type of the browser type/access service used when the access mode information of described business comprises the steps that Operational Visit/MMS sends mode/MMS content/dependences strategy names etc. and business strong correlation and the information often changed.
[Rule-Chain-Information], for Dependency Specification between transmission policy, between described strategy, Dependency Specification includes: the policy name being relied on, policy execution result code.When [Charging-Rule-Name] does not transmit, represent all of strategy, occur to be performed both by current strategies during appointment error code.It is applicable to PCRF network element and issues unified default policy.
Step 606:UE sends the service request of user and follow-up service request to PCEF network element；
The business information needed time in the step 607:PCEF network element described service request of acquisition with described first strategy matching；
Step 608:PCEF network element for business information corresponding to this service request according to PCRF network element issue based on business, it is necessary to PCEF network element judges that the decision strategy information performed carries out further decision-making implementation strategy；
In this step, whether the business information needed when PCEF network element first judges in described service request with described first strategy matching meets described first policy information, and the mode of its judgement has three kinds, specifically refers to above-mentioned, does not repeat them here.
That is, in step 607 and step 608, PCEF network element, after receiving service request, judges whether to the strategy of the further decision-making of PCEF network element according to the first policy information received, first pass through second acquisition unit and obtain the business information that further decision-making needs, then be confirmed whether to perform this strategy.
It should be noted that, if the first policy information includes Dependency Specification between strategy, then need after based on the execution result of this dependence strategy, whether decision-making performs this strategy, namely after selecting other dependence strategy execution issued of execution PCRF network element, then based on whether Policy Result decision-making performs this strategy；Other processing modes relying on strategy are remained unchanged by PCEF network element.
Subsequent step is optional step:
Step 609: when receiving business information corresponding to the UE customer service sent request and changing, PCEF network element judges whether the business information changed meets current the first policy information performing and controlling, if it is satisfied, continue to carry out policy control according to described first policy information to the business information changed；Otherwise, the current strategy performing to control is modified, activates the second default policy；And the described business information changed is carried out policy control according to the second default policy.
Step 610: operation provider sends user individual setting change to PCRF network element；
Step 611:PCRF network element sends to PCEF network element and changes policy information, and the additional conditions changed；RAR message can be passed through, but be not limited to this.
That is, only when the PCEF network element decision information of strategy changes, PCRF network element by sending strategy information such as RAR message/CCA message and changes additional conditions to PCEF network element, represent that only PCEF local policy decision information changes, namely the second policy information is sent, described second policy information is based on business after changing, strategy and charging is needed to perform the decision strategy information that network element judges to perform, based on business after described change, need strategy and charging to perform network element and judge that the decision strategy information performed is increase new policy information on the basis of the first policy information.The present embodiment for by RAR message sending strategy information and change additional conditions, shown in specific as follows:
Charging-Rule-Install field (AVP) such as increases the change additional conditions of following black portion identification in RAR/CCAI message:
The head of a family as arranged for the Type of website controls class set meal, and when the self-defined information rule of user is suitable for Type of website setting change, PCRF network element can pass through RAR message and send the Type of website information after changing to PCEF network element.
Step 612:UE sends service request and the follow-up business request of user to PCEF network element；
The step 613:PCEF network element service request to receiving and follow-up business request are according to, after the change policy information (i.e. the second policy information) received, this service request or follow-up business request being carried out policy control.
In the embodiment of the present invention, it is provided that the implementation of the set meal being controlled based on complicated data traffic information under PCC framework, effectively reduce the performance cost of PCRF network unit construction.As such as MMS complexity multimedia message charging policy easy to implement, URL classification control strategy, based on browser type and access content type policy control；Further, since PCRF network element unifies distributing policy, become unified tactical management center, it is to avoid the configuration of strategy many places, the clear division of labor interface with perimeter systems, reduces enforcement difficulty；Meanwhile, The invention also achieves the control of dependence order between strategy, reduce the performance cost frequently produced because of policy report between PCRF network element and PCEF network element.
Illustrate with concrete application example below.
Embodiment one
Assuming there is a strategy, it is necessary to judge that the content that user asks is file or picture, file is free, but picture charging.
When PCRF network element is to PCEF network element distributing policy, can directly issuing two strategies, the first strategy is file, freely；Second strategy is default policy, i.e. picture, charge；The program segment of its execution is:
PCEF network element receives when asking every time, and directly judgement is the content of this request is file or picture, if file, performs the first strategy.If picture, perform the second strategy；Compared with prior art, when judging that the content of this request is picture, after needing the content type (content-type) by request to report PCRF network element, and after the reply receiving PCRF network element, just can determine that charging or free, therefore, the interaction times between PCRF network element and PCEF network element is decreased.
Embodiment two
Example two: assume have a head of a family to control set meal, end user (i.e. the head of a family) but child is set oneself and does not allow the classification (such as social class) of online.Revise child voluntarily also by operation provider's entrance (portal) below and allow the classification (as being further added by game class etc.) of online
When child surfs the Net, PCRF network element directly issues the first strategy to PCEF network element, and this first strategy is forbidden accessing social class website: the program segment of its execution is:
After PCEF network element receives child's access request, directly judge whether it is access social class website, if, then forbid accessing, again PCRF network element is offered again after judging classification without each URL request that this child is accessed, obtain the strategy whether allowing to access, decrease the interaction times between PCRF network element and PCEF network element.
Further, when the head of a family of child can also be increased in the classification arranged by portal and not allow to access game class, PCRF network element can issue new change strategy (i.e. the second strategy) by RAR message to PCEF network element, second strategy is for forbidding accessing social class website and game class website, and the program segment of its execution is:
Afterwards, PCEF network element, when receiving the subsequent request of child, can judge whether to access game class or social class website simultaneously, if then forbidding accessing.
