Embodiment 1

[0119] Suppose there is a policy 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 charged.

[0120] When the PCRF network element issues policies to the PCEF network element, it can directly issue two policies. The first policy is a file, which is free; the second policy is the default policy, that is, pictures, which are charged; the program segment for execution is:

[0121]

[0122] When the PCEF network element receives each request, it directly judges whether the content of the request is a file or a picture, and if it is a file, executes the first strategy. If it is a picture, execute the second strategy; compared with the prior art, when judging that the content of the request is a picture, after the content type (content-type) of the request needs to be reported to the PCRF network element, and after receiving the PCRF network element Only after the response is received, can it be determin...

example 2

[0124] Example 2: Suppose there is a parental control package, the end user (ie the parent) can set the category (such as the social category) that the child is not allowed to surf the Internet. Later, you can also modify the categories that children are allowed to surf the Internet through the portal of the operator (such as adding games, etc.)

[0125] When the child surfs the Internet, the PCRF network element directly issues the first policy to the PCEF network element. The first policy prohibits access to social networking sites: the program segment executed by it is:

[0126]

[0127] After the PCEF network element receives the child's access request, it directly judges whether it is a social networking website, and if so, prohibits the access, instead of judging the classification of each URL request accessed by the child, and then re-reporting to the PCRF network element to obtain whether The strategy of allowing access reduces the number of interactions between PCR...

Abstract

An embodiment of the invention provides a policy control method, a policy control device and a policy control system for data services. The method includes: acquiring first policy information from a policy and charging rule function network element, wherein the first policy information is decision policy information needing to be judged and enforced by a policy and charging enforcement function network element based on the services; when a service request is received from a user, acquiring service information needed in match with the first policy information from the service request; and when the service information satisfies the first policy information, performing policy control for the service information according to the first policy information. The method, the device and the system in the embodiment solve the technical problem of more interactive times between the PCRF (policy and charging rule function) network element and the PCEF (policy and charging enforcement function) network element in policy control of frequently modified service request information or result associated policy control in the prior art.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a policy control method, device and system for data services. Background technique [0002] Policy and Charging Control (PCC, Policy and Charging Control) architecture is an architecture system proposed by the R7 version of the 3GPP organization standard system after integrating policy control and flow-based charging. It is used for packet network business data transmission quality of service (QoS ) and other policy control and flow accounting technology architecture. In the PCC architecture, the policy and charging rule (PCRF, Policy and Charging Rule Function) network element centrally manages the control and charging policy of data services, and the policy and charging enforcement (PCEF, Policy and Charging Enforcement Fucntion) network element is responsible DPI identification and policy execution aim to provide users with differentiated services, provide ...
