Diameter Gateway Support for 5G Non-Standalone Architecture

MATRIXX supports 5G Non-Standalone Architecture deployments by including extended fields for 5G RAN in Gx messages to enable the high-bandwidth data flows available in 5G networks.

When you create a QoS Info profile in My MATRIXX, you can select Use Extended Fields for 5G RAN so that the PCRF populates the following AVPs in Gx CCA/RAR top-level QoS-Information AVPs:
  • Extended-APN-AMBR-UL — The maximum aggregate bit rate in kilobits per second for the uplink direction across all non-GBR bearers related with the same
  • APN Extended-APN-AMBR-DL — The maximum aggregate bit rate in kilobits per second for the downlink direction across all non-GBR bearers related with the same APN.

When selected, the Extended-APN-AMBR-DL/UL AVPs are used instead of the APN-Aggregate-Max-Bitrate-UL/DL AVPs.

When configuring pricing for 5G Non-Standalone Architecture deployments, you should segment the 4G E-UTRAN and 5G NR Radio Access Types by normalizing on the RatType field in the MtxDiamGxCCMsg MDC. Valid Rat Types are listed in 3GPP specification 29 212 v16 (section 5.3.31 RAT-Type AVP).

For information about normalization, see the discussion about normalization in MATRIXX Pricing and Rating. For information about creating QoS profiles, see the discussion about creating QoS profiles in My MATRIXX Help.
