MATRIXX SBA Gateway
This section describes the Service Based Architecture (SBA) Gateway, which provides the framework to build 5G network function (NF) services based on 3GPP technical specifications.
Upgrading SBA Gateway
When upgrading to a new version of SBA Gateway, there are several things you must consider to ensure the upgrade is successful and the correct configuration is applied.
Pinning SBA Network Functions
SBA Gateway network functions (for example, CHF) are stateless components. This means that when upgrading, you can install the latest version of that network function (NF).

- About MATRIXX 5G Integration
  MATRIXX 5G Integration describes how to implement the Service-Based Architecture (SBA) Gateway and messaging. In addition, this document provides information about security configuration (secured and not secured).
- MATRIXX SBA Gateway
  This section describes the Service Based Architecture (SBA) Gateway, which provides the framework to build 5G network function (NF) services based on 3GPP technical specifications.
  - MATRIXX SBA Gateway Overview
    SBA Gateway converts incoming 5G JSON messages to MATRIXX Data Containers (MDCs) and forwards these requests to the Traffic Routing Agent (TRA), which routes them to the correct sub-domain on MATRIXX Engine. Outgoing messages are converted from MDCs to 5G JSON messages.
  - Installing SBA Gateway
    This section describes installing SBA Gateway in hybrid deployments and installing CHF within an Istio service mesh.
  - Upgrading SBA Gateway
    When upgrading to a new version of SBA Gateway, there are several things you must consider to ensure the upgrade is successful and the correct configuration is applied.
    - Pinning SBA Network Functions
      SBA Gateway network functions (for example, CHF) are stateless components. This means that when upgrading, you can install the latest version of that network function (NF).
  - Viewing the SBA Gateway Version
    You can use version, revision, and timestamp data to check which version of SBA Gateway is running.
  - Configuring SBA Gateway
    SBA Gateway is configured as 5G network functions in several ways.
  - Monitoring and Logging
    You administer the SBA Gateway by configuring its logging and monitoring features. For more information about monitoring SBA Gateway administration tasks, see the discussions about monitoring SBA Gateway and configuring the SNMP Prometheus adapter in MATRIXX Monitoring and Logging.
  - Creating a Mapping Configuration
    The following documentation provides information about how to create a mapping configuration. For a list of 5G message mappings from MATRIXX Data Container (MDCs) to OpenAPI supported by MATRIXX, see the discussion about MATRIXX 5G message mapping.
  - Security
    SBA Gateway supports HTTP BASIC authentication and TLS Mutual Authentication.
  - API for 5G Integration
    The URI, mapping, and OpenAPI specification are configurable, and only the HTTP method and mapping filename are not.
  - Throttling
    SBA Gateway can be throttled to protect the platform from overload conditions.
  - Connecting to Multiple Networks with Multus
    Depending on requirements, SBA Gateway might require a dedicated connection to the 5G network separate from its connection to other MATRIXX components.
  - MATRIXX 5G Message Mapping
    The following sections describe the default configuration for SBA Gateway-supported 5G message mapping. Topics in the following sections describe the mappings from MATRIXX Data Container (MDC) format to OpenAPI format for each 3GPP 5G version.
- Charging Function
  This section describes the Charging Function components and how to deploy and configure them.

Pinning SBA Network Functions

SBA Gateway network functions (for example, CHF) are stateless components. This means that when upgrading, you can install the latest version of that network function (NF).

Important: When upgrading SBA Gateway as part of upgrading a MATRIXX deployment, upgrade the SBA Gateways first and pin them to the pre-upgrade version of MATRIXX Engine. After MATRIXX Engine has been upgraded, unpin SBA Gateway so that it can communicate on the same version level as the upgraded engine.
