Aviz Service Node summarizes how it processes Diameter GX signaling to build subscriber policy session records from CCR and CCA messages. The post frames this capability as operational visibility for mobile core teams that need to track policy, charging, QoS, and session state.

Research Overview

The blog describes Diameter GX as the interface that connects PCRF and PCEF functions in a mobile core network. It states that the interface carries policy and charging rules used to manage subscriber sessions in real time.

It also says each session can include identifiers, charging rules, QoS values, access context, and bearer information. Aviz Service Node, or ASN, is presented as a system that correlates those messages into a session record.

Key Findings

ASN is described as supporting CCR and CCA message handling across the session lifecycle. The post says it uses an AVP merge model so newer attribute values overwrite earlier ones while new attributes are retained.

When multiple sessions exist for the same IMSI, the system replaces older records with newer ones and exports the prior state with priority handling. The blog says ASN can manage up to 3 million concurrent Diameter GX sessions.

Technical Breakdown

The article lists the session data ASN extracts, including IMSI, IMEI, MSISDN, session IDs, host and realm data, and the last seen message. It also includes user context such as UE IP address, APN, IP-CAN type, RAT type, SGSN address, GGSN address, and AN-GW address.

For charging and policy details, the export can contain rule base names, rule names, rule types, rating groups, charging mode, flow status, and uplink and downlink flow rules. For QoS, it includes QCI, maximum uplink and downlink bit rates, APN aggregate bandwidth, priority level, and pre-emption settings.

Operational Impact

The post says this consolidated view helps operators verify policy rules, check QoS settings, monitor charging updates, and troubleshoot session creation, modification, and termination. It also says the exported state can be sent through Kafka, keyed by IMSI, for downstream analytics and observability tools.

ASN is presented as reducing the need to inspect individual Diameter packets. The blog says its session view provides a single record of subscriber policy activity and related rule changes.

Leadership Perspective

For mobile core teams, the article positions Diameter GX visibility as a way to monitor policy delivery and enforcement across subscriber sessions. It also notes that session export includes lifecycle timing and status, including normal and priority exports.

The post closes by linking the signaling data to policy enforcement, charging, QoS, and session management. This Blog Summary is a fact-based summary of the vendor blog.
