Note:

For information about upgrade planning and required procedures before the upgrade, refer to the DSR Software Upgrade Guide.

The following features and enhancements that are introduced in this release.

  • SDS Provisioning Capacity Uplift to 800 TPS: The Transaction Provisioning System (TPS) is updated for subscriber database processor for address resolution and subscriber location functions. For more information, see Oracle Communications Diameter Signaling Router Cloud Benchmarking Guide.
  • Increase the APN Limit from 2000 to 8000: An Access Point Name (APN) is a unique packet data network identifier. The PCA uses configured Access Point Names to validate APN entries received in Diameter signaling, and to apply appropriate stale session timeout values during database audits. For more information, see Oracle Communications Diameter Signaling Router Policy and Charging Application User Guide.
  • Egress Throttle limit from 128 to 512 in DRA: An Egress Throttle Group is a collection of Diameter Connections or Peers, or both, that are logically grouped together to monitor Egress Message Rate and Pending Transactions for multiple Peers and Connections across multiple DA-MPs on a Network Element. For more information, see Oracle Communications Diameter Signaling Router Diameter User Guide.
  • Timeout based redirection across RGs: DSR can re-route request to peer or connection within the same route group up to a specified number of times as defined in Max number of retry within same Route Group. When the count of reroutes attempts reaches the maximum limit, it re-routes the request to the next route group based on their priority. For more information, see Oracle Communications Diameter Signaling Router Diameter User Guide.
  • LDAP to support dot symbol and 30 characters username length: If the user account name has "@" symbol, LDAP Authentication checks for the suffixed domain name in the list of configured LDAP Servers. It then connects to the first available server with a matching domain name to perform the authentication. If this server is not reachable, it proceeds to the next server with a matching domain name. For more information, see Oracle Communications Diameter Signaling Router Operations, Administration, and Maintenance Guide.
  • Interface Level Report: The Interface Level Report allows the user to determine the number of total, successful, and rejected messages forwarded and received to or from DSR over a connection on a diameter interface. For more information, see Oracle Communications Diameter Signaling Router Diameter User Guide.and Oracle Communications Diameter Signaling Router Measurement Reference Guide.
  • Error codes counter peg at individual error code level: For each Policy and Charging Site, the Diameter Error Result Code value to send to the Request initiator for policy related errors can be configured according to which condition applies. Each condition can be mapped to a different Result Code for each supported interface. For more information, see Oracle Communications Diameter Signaling Router Measurement Reference Guide.
  • DSR Wallaby Support: Oracle Communications Diameter Signaling Router is supported on OpenStack Wallaby.
