Charging Configuration
Charging Configuration has the interfaces you use to create and manage balance, pricing, product offer and bundle, general, and application-related components.
Normalizer Configuration
Normalizer Configuration contains interfaces you use to create and manage normalizers, normalizer templates, and normalizer value lists.
Normalization
MATRIXX Engine uses a process called normalization to condense large sets of discrete field values into a manageable set of parameters. Each single normalizer parameter value represents an aggregate value set, so that assigning a result to every possible field value is not required.
Time Normalizer
The time normalizer determines a result by comparing the start time of an event with multiple time ranges and matches the time into one range. A different result can be selected if the event spans multiple time ranges.

  - Normalizer Configuration
    Normalizer Configuration contains interfaces you use to create and manage normalizers, normalizer templates, and normalizer value lists.
    - Normalization
      MATRIXX Engine uses a process called normalization to condense large sets of discrete field values into a manageable set of parameters. Each single normalizer parameter value represents an aggregate value set, so that assigning a result to every possible field value is not required.
      - Balance Difference Normalizer
        A balance difference normalizer chooses a result by comparing the following values to ranges of balance differences specified in the normalizer:
      - Balance Distribution Normalizer
        The balance distribution normalizer compares a balance or meter quantity to ranges of quantity values defined in the normalizer and matches the quantity to one range. The ranges must cover from negative infinity to infinity, with no gaps, and are used to choose a result.
      - Balance Spendable Normalizer
        The balance spendable normalizer determines whether any amount of a balance (or set of balances of the same class) is available for usage charging. The balance spendable normalizer is similar to a balance distribution normalizer in that normalization is based on an available balance amount with two ranges, the first range being less than or equal to zero and the second range being greater than zero.
      - Closed User Group Normalizer
        The closed user group normalizer, depending on configuration, either compares whether the subscription initiating an event is in the same group as the subscription receiving the event, or whether the subscription initiating an event is on the same same sub-domain as the subscription receiving the event.
      - Date Set Match Normalizer
        The date set match normalizer compares the time of an operation, such as the event time in a Diameter message, with a list of dates or datetimes saved in a _glossary/mdc.html, such as a custom subscriber or device MDC. If the operation is on a date included in the list in the specified MDC field, the normalizer evaluates to a match.
      - Difference Range Normalizer
        The difference range normalizer compares the following numeric values (integer or decimal) to ranges of differences specified in the normalizer:
      - Eligibility Feature Match Normalizer
        The eligibility feature match normalizer compares the feature defined in the normalizer with all the features of all the catalog items owned by a subscription, group, or device, to look for a match.
      - IP Address Normalizers
        IP address normalizers specify one or more IP addresses, defined by the normalizer as strings using the Classless Inter-Domain Routing (CIDR) notation, with which to compare an IP address value in the network message. If a match is found, the index associated with that IP address is used. A specified IP address can be an exact address or it can contain an optional network mask to denote a range of IP addresses.
      - Multiplexing Normalizer
        Multiplexing normalizers reference one or more other normalizers. During authorization and rating, a multiplexing normalizer checks the fields used by its referenced normalizers. If a field used by one of the referenced normalizers is a valid field in the message being processed, then the referenced normalizer is selected and executed for rating. A normalizer that does not normalize on MATRIXX Data Container (MDC) fields should not be referenced by a multiplexing normalizer.
      - Numeric Equality Normalizer
        Numeric equality normalizers have two types, one for signed integers and one for unsigned integers. Each one chooses a result by comparing the numeric value in a specified MATRIXX Data Container (MDC) field to one or more values of the same type specified in the normalizer. If a match is found, rating uses the index associated with that numeric value.
      - Numeric Range Normalizer
        Numeric range normalizers have three types, one for signed integers, one for unsigned integers, and one for decimals. Each one chooses a result by comparing a numeric value in a specified MATRIXX Data Container (MDC) field to numeric ranges specified in a normalizer. On finding a match, rating uses the index associated with that range.
      - Phone Number Match Normalizer
        The phone number normalizer compares a phone number value in the network message to one or more phone number prefixes specified as normalizer parameters. If the leading digits of the phone number matches one of the specified phone number prefixes, the index associated with that value is used.
      - Phone Number Pattern Match Normalizer
        The phone number pattern match normalizer uses complex strings (patterns) with ranges to represent a set of one or more phone numbers. It then compares a phone number value in the network message to each pattern specified as a normalizer parameter. If the phone number value matches one of the specified number patterns, the index associated with that value is used. The phone number pattern match normalizer can match strings that contain more than 15 digits, or that include the following characters: #, *, a, b, c, A, B, C, D, or E.
      - Phone Number Set Contains Normalizer
        This normalizer compares a phone number or string field in any MDC, for example, in the Diameter message, with a set of phone numbers stored in any MATRIXX Data Container (MDC), such as an extended subscriber object or group object MDC to see if the set contains the exact same phone number.
      - Quantity Distribution Normalizer
        The quantity distribution normalizer defines ranges of usage quantities that can be associated with different rating results. It operates on the aggregated session quantity.
      - String Match Normalizer
        A string match normalizer compares a string value in a specified field to a list of strings specified as normalizer parameters. The comparison can be configured to match characters starting at the beginning of the string (a prefix match) or the end of the string (a suffix match). If a match is found, the result associated with that string is used. Each specified string value can be configured to be an exact match or a closest match. In the case of a closest match, the string with the longest matching characters is used.
      - String Set Matches Normalizer
        The string set matches normalizer compares a value in a MATRIXX Data Container (MDC) field with a value in another MDC field. Both fields can either be a single string/phone number or a list/array of strings/phone numbers. The comparison could be an exact match, prefix match, or suffix match. If one field is an array/list and one field is a single value, then the system checks if anything in the list/array matches the single value (using the match mode). If a match is found, then the normalizer evaluates to true. It does not matter which field is the list/array and which is the single value. If both are arrays/lists, then the system checks if a value in one list/array matches any value in the other list/array.
      - Time Normalizer
        The time normalizer determines a result by comparing the start time of an event with multiple time ranges and matches the time into one range. A different result can be selected if the event spans multiple time ranges.
      - Time Interval Range Normalizer
        A time interval range normalizer chooses a result by comparing a time interval to time interval ranges specified in the normalizer. For each matching range, rating uses the index associated with that range.
      - Zoning Normalizer
        The zoning normalizer determines a result by comparing two specified field values with a list of paired values listed in From and To fields.
    - Normalizer Templates
      Normalizer templates identify the MATRIXX Data Containers (MDCs) and MDC fields, balances, quantities, or times that rating uses for normalization when deciding which rates to apply. Normalizer templates that perform normalization based on one or more field values require you to specify the field and the MDC containing it.
    - Normalizers
      You use normalizers to select a balance, rating formula, or policy profile, or to prioritize product offers in real-time during rating. You can reuse normalizers in balance filters, rate tables, policy tables, GL transaction type tables, GL account tables, and product offer priority generators.
    - Normalizer Value Lists
      A normalizer value list is used to define a list of values available to a normalizer. The values in a normalizer value list can be shared between multiple normalizers, ensuring that they all have the same list of values and indices in a matrix. For example, all the normalizers referenced in a multiplexing normalizer must use the same normalizer value list to ensure that they all have the same values.
    - Normalizer MDCs
      The following MATRIXX Data Containers (MDCs) have fields that can be used during normalization:
  - Tax Configuration
    Tax Configuration contains interfaces you use to create and manage tax classes and selectors, and US taxation. You must have the Manage Tax domain user role to enable this menu.
  - General Configuration
    General Configuration has interfaces you use to create pricing plan components. Pricing plan components managed through this interface include announcements, product and system attributes and definitions, currency codes for rate tables, denial codes, field definitions for use in normalizers and rate tables, Diameter Final-Unit-Indication (FUI) profiles and generators, General Ledger (GL) transaction types and info generators, grace period profiles, languages, notification profiles, parameter definitions, pre/post-rating profiles and generators, SH Repository data, Subscriber Information Query components, tax classes for offer categorization, usage quota profiles and components, purge profiles, virtual fields, and usage triggers.
  - Application Configuration
    Application Configuration components are used by My MATRIXX for creating pricing plan items and are used by MATRIXX Charging Application and MATRIXX Policy Application for charging and rating.
- Policy Configuration
  Policy configuration components are used by MATRIXX Charging Application and MATRIXX Policy Application for charging and rating.

Time Normalizer

The time normalizer determines a result by comparing the start time of an event with multiple time ranges and matches the time into one range. A different result can be selected if the event spans multiple time ranges.

The most common methods of time rating are by time-of-day and day-of-week, such as rating based on weekdays verses weekend, and peak hours verses off-peak hours. Time ranges cannot span across days, but you can implement this behavior by specifying a range that ends at midnight one day, for example, Monday, and a second range that starts at the beginning of the next day (Tuesday).

The time normalizer template also specifies which time zone to use—the subscriber's home time zone, the time zone where the event was initiated, or the time zone specified for the MATRIXX Engine installation. Once the time zone is determined, the timestamp is used to assign the result. If the time zone is not specified in the time normalizer template, the event time zone is used during rating. In such cases, the normalization is based on the time of day of the event, interpreted in the UTC offset contained in the event message.
