- About My MATRIXX Help
  My MATRIXX Help provides information about My MATRIXX, a web application that offers a central location for creating pricing plans and configuring MATRIXX charging and rating behaviors. My MATRIXX is intended for pricing administrators who are responsible for creating and maintaining pricing plans and for IT administrators or developers who configure the rating and charging behavior of the online charging system.
- Introducing My MATRIXX
  The following information describes the My MATRIXX interface.
- Using My MATRIXX
  You use My MATRIXX to validate and compile the pricing configuration file, compile pricing, and set up and manage user roles and domains; create and manage catalog items and catalogs, manage eligibility features and rules, and manage the Normalizers interface; create and manage balances, pricing, offers and bundles, general components, and application-related components; and policies for charging and rating. Use General Configuration to create components that support pricing items and charging functionality such as announcements pricing components, attribute definitions, denial codes, products, decision tables, Final Unit Indication (FUI) profiles and generators, general ledger transaction types, notification profiles, normalizer templates, and subscriber information query actions, profiles, and generators.
- Home Menu
  The following information describes the tasks that can be performed using the My MATRIXX Home menu.
- Catalog Configuration
  Catalog Configuration contains the Catalog Items interface that you use to create, change, or delete catalog items; the Eligibility interface to manage eligibility features and rules to determine whether a subscriber, group, or device is eligible for a catalog item; and the Normalizers interface you use to edit normalizers.
- Charging Configuration
  Charging Configuration has the interfaces you use to create and manage balance, pricing, product offer and bundle, general, and application-related components.
- Policy Configuration
  Policy configuration components are used by MATRIXX Charging Application and MATRIXX Policy Application for charging and rating.
  - Policy Overview
    You must have the Pricing User domain role to access this menu and all its components. For more information, see the discussion about technical user roles.
  - Policy Session Mappings
    In MATRIXX 3G, 4G, and 5G environments using MATRIXX Policy Application, each policy session includes an Attr field of type MtxPolicySessionExtension that includes any custom policy session fields. You can map fields in the incoming network message to these Attr fields, or to any custom MATRIXX Data Container (MDC) fields that extend it, to save the field value throughout Gx, N40, Sy, and N28 policy sessions. This allows you to set up rating based on that value.
  - Policy Components
    The 5G MATRIXX policy components include spending limit configuration components. The 3G/4G MATRIXX policy components include spending limit configuration components, session management policy components, policy session mappings, event trigger groups, and event triggers.
  - Event Trigger Groups
    Diameter Gx event triggers define when the PCEF is notified of changing network conditions. An event trigger group is a collection of event triggers that are assigned to a policy profile.
  - Event Triggers
    Gx event triggers tell the Policy and Charging Enforcement Function (PCEF) which network events must send a new Credit-Control Response (CCR) to the Policy and Charging Rules Function (PCRF) for a possible policy change. Each event trigger has a string value name and an associated non-negative integer value.
  - Spending Limit Configuration
    Configure the spending limit control components when using a Policy and Charging Rules Function (PCRF) or Policy Control Function (PCF) that is external to MATRIXX Engine. For 5G MATRIXX environments, the spending limit control configuration reference point (N28) is located between your external PCF and MATRIXX Engine as a Charging Function (CHF). For 3G/4G environments, the spending limit control configuration reference point (Diameter Sy) is located between an external PCRF and MATRIXX Engine as an OCS.
  - Session Management Policy Configuration
    The Gx session management policy reference point is located between a Policy and Charging Enforcement Function (PCEF) and the Policy and Charging Rules Function (PCRF) internal to MATRIXX.
    - Session Management Policy Components
      A session management policy component implements the business logic that decides which PCC rules are returned to the PCEF for a given set of circumstances.
    - Session Management Policy Profiles
      The Gx Session Management profiles contain the criteria that determine the Policy and Charging Control (PCC) Rule returned to one or more Policy and Charging Enforcement Functions (PCEFs) in response to a Credit-Control Response (CCR) or when there is a subscriber status change.
    - PCC Rules
      PCC (Policy and Charging Control) Rules define the treatment to apply to subscriber traffic based on the application used by the subscriber, or on information about the data flow. You configure PCC rules that are activated either dynamically or by the _glossary/pcrf.html.
    - QoS Profiles
      QoS profiles define the quality of service provided by a specific policy profile. Multiple QoS profiles can be assigned to a policy profile.
      - Create a QoS Profile
        A QoS profile defines the quality of service provided by a specific policy profile. You can create QoS Info profiles and Default EPS Bearer profiles.
      - Change a QoS Profile
        A change to a QoS profile affects any session management policy profiles to which it is assigned.
      - Delete a QoS Profile
        Deleting a QoS Profile removes it from the pricing plan.
      - Session Management QoS Info Properties
        Use the Edit QoS Profile interface to change the session management QoS info properties.
      - Session Management Default EPS Bearer Properties
        Use the Edit QoS Profile interface to change the default EPS bearer QoS profile properties.

Session Management Default EPS Bearer Properties

Use the Edit QoS Profile interface to change the default EPS bearer QoS profile properties.

Configure the properties in Session Management Default EPS Bearer Properties in the Workspace after creating a Default EPS Bearer QoS profile.

Table 1. Session Management Default EPS Bearer Properties
Property	Description
Name	The name of the QoS profile.
Description	Information about the QoS profile.
QoS Profile Type	Read only QoS profile type (Default EPS Bearer).
QoS Class Id	The QoS class identifier (QCI) defines the traffic priority, packet error loss rate and acceptable packet delay. 3GPP defines nine QoS classes. Four classes (1-4) trigger the establishment of a dedicated bearer (GBR). Five classes (5-9) trigger the establishment of a non-dedicated bearer (non-GBR).
Priority Level	Allocation Retention Policy (ARP) controls what happens when there are insufficient resources to establish a new EPS bearer. Values are 1-15 with 1 being the highest priority. Priority levels 1-8 should be assigned only to resources for services that are authorized to receive prioritized treatment within an operator domain. Priority levels 9-15 can be assigned to resources that are authorized by the home network and therefore applicable when a user equipment (UE) is roaming.
Preemption Capability	Determines if a bearer with a lower ARP priority level should be dropped to free up the required resources. Values are `0` (no) or `1` (yes).
Preemption Vulnerability	Determines if a bearer with a lower ARP priority level should be dropped by a preemption capable bearer with a higher priority value to free up the required resources. Values are `0` (no) or `1` (yes).
