The UDRs in PCRF.Rules store information about different rules regarding the provided quality of service for different subscribers.

See 4.2 APL - PCC Runtime Support for further information about how to use the PCC.Rules UDRs with APL.

The main objects of PCRF.Rules are:

Object	Description
Rules_Mapping	A flexible mapping table used to map from an external representation to a list of rules. The mapping should not include any information related to a specific subscriber.
Rules	Rules contains the rule settings regarding quality of service and charging that should be applied for the subscribers.

Overview of the Rules Data Model

The different UDRs within the Rules Data Model are connected as follows:

Overview of the Rules Data Model

RulesMapping UDR

In the RulesMapping UDR you set up the priority for the rules mapping, the product, enforcements, notifications, etc that the rules mapping should use and the PCC rules that should be applied.

Field	Description
`ID (int)`	The unique ID of the rules mapping table.
`Priority (int)`	The priority of the mapping item, a low value indicates a high priority. Determines the order in which the matched mapping objects are returned.
`Arguments (list<string>)`	The arguments of a mapping object e g the product. The arguments are stated with regular expressions, which means that entering "Products [2-5]" will match Products 2, 3, 4, or 5.
`Targets (list<PCC_Rule>)`	The different rules used by the mapping object, see the section below PCC_Rule UDR.
`StopFallthrough (boolean)`	Used in the rules selection process. If several rules apply, but the one with highest priority has been configured with `StopFallthrough` set to `Yes` in the APL code, only this rule will be returned if it is active. If it is not active, all other active rules that apply will be returned.

title	Example RulesMapping UDR

The following values:

Code Block
ID=11 Priority=2 Arguments=['Product 1'] Targets=[1,2] ID=12 Priority=1 Arguments=['Product 2-4'] Targets=[3] StopFallthrough=yes

will give the following setup:

The second mapping table, with priority 1, will have higher priority than the first one, with priority 2.
The first mapping table use the product Product 1, while the second mapping table use the products Product 2, Product 3, or Product 4.
The first mapping table uses PCC Rules with IDs 1 and 2, while the second mapping object uses the rule with ID 3.
If the second mapping table is active, only the rules for this table will be returned even if other rules apply.

PCC_Rule UDR

In the PCC_Rule UDR you determine the period during which the rule should be active, the charging rule that should be applied and the quality of service that should be applied for the rule.

Field	Description
`ID (int)`	The unique ID of the rule.
`Period (string)`	The activity period that the rule should have, see

2.2

Periods Data Model Rules.
`Charging_Rules (list<Charging_Rule (PCRF.Rules)>))`	The charging rules that should be applied for this rule, see the section below, Charging_Rule UDR.
`Rule_Name (string)`	The name of the rule.
`QoS (QoS_Information (PCRF.Rules)`	The quality of service that should be applied for this rule, see the section below, QoS_Information UDR.

Below is a screenshot of the UDR Assistance displaying the Rules UDR:

will give the following setup:

The IDs used for the three rules; 1,2 3, are the IDs stated as Targets in the mapping tables, see the section above, RulesMapping UDR.
The three rules are active during three different periods; WEEKDAYS, NIGHTS and WEEKENDS, see 2.2 Periods Data Model Rules.
Rule number 1 uses the charging rule with ID 1, rule number 2 uses charging rule with ID 3 and rule number 3 uses charging rule with ID 5, see the section below, Charging_Rule UDR.
The names of the rules are PRIMARY, SECONDARY and THIRD.
The first rule uses QoS ID 20, the second rule uses QoS ID 10 and the third rule uses QoS ID 30, see the section below, QoS_Information UDR.

Charging_Rule UDR

In the Charging_Rule UDR you determine the Static, Dynamic or Final Indication that should be used for the charging rule.

Field	Description
`ID (int)`	The unique ID of the charging rule.
`Name (string)`	The name of the charging rule.
`Static_Rule (Static_Rule (PCRF.Rules))`	The static rule that should be applied, see the section below, Static_Rule UDR.
`Dynamic_Rule (Dynamic_Rule (PCRF.Rules))`	The dynamic rule that should be applied, see the section below, Dynamic_Rule UDR.
`Final_Indication_Rule (Final_Indication_Rule (PCRF.Rules))`	The final indication rule that should be applied, see the section below, Final_Indication_Rule UDR.

Note

title	Note

The Charging rule only indicates one type of rule; static, dynamic or final indication, not a combination.

The second charging rule, with ID 3 and name Secondary, uses the static rule with ID 112.
The third charging rule, with ID 5 and name Rest, uses the final indication rule with ID 200.
