学习5G知识，势必要去阅读相关的技术标准，而纯英文的标准协议对于初学者来说是个门槛。

个人在学习5G标准3GPP TS 29244-g30过程中，也发现google的机器翻译实在晦涩难懂，所以个人在借助百度翻译（中国人更懂中文）的同时，人工对每句话进行了校对。

在自己学习的同时，也将翻译内容分享给给广大网友。由于个人能力有限，翻译不到位的地方还请各位网友们指正。

5.4.9 Provisioning of Predefined PCC/ADC Rules 提供预定义的PCC/ADC规则

A Predefined PCC rule is preconfigured in the PCEF, e.g. a PGW (for EPC) or SMF (for 5GC). Predefined PCC rules can be activated or deactivated by the PCRF/PCF at any time. The Predefined PCC rules may be grouped allowing the PCRF/PCF to dynamically activate a set of PCC rules.

预定义的PCC规则在PCEF中预先配置，例如PGW或SMF。PCRF/PCF可以随时激活或停用预定义的PCC规则。预定义的PCC规则可被分组以允许PCRF/PCF动态地激活一组PCC规则。

For EPC a predefined ADC rule is preconfigured in the TDF. In the case of solicited reporting, the Predefined ADC rules can be activated or deactivated by the PCRF at any time. Predefined ADC rules within the TDF may be grouped allowing the PCRF to dynamically activate a set of ADC rules.

对于EPC，TDF中预先配置了预定义的ADC规则。在请求报告的情况下，PCRF可以随时激活或停用预定义的ADC规则。TDF内的预定义ADC规则可被分组以允许PCRF动态地激活一组ADC规则。

For the definition of PCC and ADC rules see clauses 4.3.1 and 4b.3.2 of 3GPP TS 29.212 [8] and clause 5.6.2.6 of 3GPP TS 29.512 [41].

有关PCC和ADC规则的定义，请参见3GPP TS 29.212 [8]的条款4.3.1和4b.3.2和3GPP TS 29.512 [41]的条款5.5.6.6。

The CP function may enforce an activated predefined PCC or ADC rule by the PCRF/PCF in the UP function by:

CP功能可以通过以下方式在UP功能中通过PCRF/PCF强制执行激活的预定义PCC或ADC规则：

- determining the service data filters or application IDs referred by the activated predefined PCC or ADC rule(s) and the corresponding QoS and charging control information respectively;

-分别确定由激活的预定义PCC或ADC规则引用的业务数据过滤器或应用ID以及相应的QoS和计费控制信息；

- creating the necessary PDR(s) to identify the service data flow(s), application(s) that the predefined PCC or ADC rule refer to, if not already existing;

-创建必要的PDR，以识别预定义PCC或ADC规则引用的业务数据流、应用程序（如果尚未存在）；

- creating the necessary QER for the QoS enforcement at service data flow or application level accordingly;

-为业务数据流或应用层的QoS实施创建必要的QER；

- creating the necessary FAR if a new FAR needs to be created as result of Bearer binding (for EPC) or QoS flow binding (for 5GC) and QoS control for forwarding the detected service data flow or application traffic, or to redirect or to apply traffic steering control if included in the predefined PCC/ADC rule;

-如果由于Bearer绑定或QoS流绑定以及用于转发检测到的业务数据流或应用流量的QoS控制而需要创建新的FAR，或者如果预定义PCC/ADC规则中包括重定向或应用流量导向，则创建必要的FAR；

- creating the necessary URR(s) for each monitoring key, charging key, combination of Charging Key and Service ID, or combination of Charging Key, Sponsor ID and Application Service Provider Id if included in the predefined PCC or ADC rule;

-为每个监控密钥、计费密钥、Charging Key和Service ID的组合，或Charging Key、Sponsor ID和Application Service Provider ID的组合（如果包括在预定义的PCC或ADC规则中）创建必要的URR；

and then:

- associating the created URR(s) to the newly created PDR(s);

-将创建的URR与新创建的PDR相关联；

- associating the existing FAR or the new FAR to the newly created PDR(s);

-将现有FAR或新FAR与新创建的PDR相关联；

Optionally, the traffic handling policies common to many PFCP sessions (i.e. predefined PDR(s) / QER(s) / FAR(s) / URR(s)) may be configured in the UP function. The CP function may activate these traffic handling policies by including the Activate Predefined Rules IE within:

可选地，可以在UP功能中配置许多PFCP会话共用的流量处理策略。CP功能可以通过在以下内容中包括Activate Predefined Rule IE来激活这些流量处理策略：

- the Create PDR IE in a PFCP Session Establishment Request; or

-PFCP Session Establishment Request中的创建PDR IE；或

- the Update PDR IE in a PFCP Session Modification Request.

-PFCP Session Modification Request中的Update PDR IE。

For traffic matching PDR(s) associated with the activated predefined rules, the UP function shall enforce the rules, e.g. for URR, the UP function shall generate Usage Report(s) and send it to the CP function and the CP function shall be able to handle the usage reports as described in clause 5.2.2.

对于与激活的预定义规则相关联的匹配PDR的流量，UP功能应执行这些规则，例如，对于URR，UP功能应生成Usage Report并将其发送给CP功能，CP功能应能够处理使用情况报告。

NOTE: The URR IDs used in reports triggered by a predefined rule in UP function are also pre-configured at the CP function.

注意：由UP功能中的预定义规则触发的报告中使用的URR ID也已在CP功能中预先配置。

For deactivating predefined rules which are activated in the UP function, the CP function shall include the Deactivate Predefined Rules IE in the Update PDR IE in a PFCP Session Modification Request to inform the UP function to deactivate the corresponding predefined rules for the related PDR.

对于停用在UP功能中激活的预定义规则，CP功能应在PFCP Session Modification Request中包括Update PDR IE中的Deactivate Predefined Rules IE，以通知UP功能停用相关PDR的相应预定义规则。
