Policy and Charging Configuration Overview

The Policy and Charging > Configuration pages for Policy and Charging components provide fields for entering the information needed to manage Policy and Charging configuration in the DSR.

The Policy and Charging application must be activated in the system before PCA configuration can be performed.

The DSR 3-tiered Operations, Administration, and Maintenance (OAM) topology is required for the Policy and Charging application. 3-tiered OAM topology consists of the several tiers:

• A pair of NOAM servers running in active/standby redundancy

  OAM configuration is performed on the NOAM.

  Network-wide Policy and Charging configuration is performed on the NOAM.

• A pair, triplet, or quadruplet of SOAM servers at each site running in active/standby, active/standby/spare redundancy, or active/standby/spare/spare redundancy

  Diameter protocol configuration is done on the SOAM.

  Most DSR Application configuration is done on the SOAM.

  Site-specific configuration for Policy and Charging is performed on the SOAM; all network-wide Policy and Charging configuration components are viewable on the SOAM.

• A set of MP servers, which can host signaling protocol stacks (such as DA-MPs) or in-memory database servers such as a Session Binding Repository (SBR) or IPFE servers.

An optional pair of Disaster Recovery NOAMs can be configured to manually take over in the event of loss of both the active and standby NOAMs

The three tiers allow configured data to be replicated down to the MP servers, and measurements, events, and alarms to be merged up to the OAM servers.

Three-tiered topology allows administrators to access all DSR GUI pages from a single sign-on. An administrator can access the DSR SOAM when logged into the DSR NOAM, without needing to re-enter login credentials.
