Release 24.3.0

Policy includes the following features or enhancements:

PCRF Core Pod Congestion Control: The PCRF Core service supports Pod Congestion Control mechanism that helps to handle heavy traffic of incoming requests. It considers every incoming request and decides to either reject or accept it based on a defined request priority and the status of service congestion level. For more information, see the "PCRF Core Pod Congestion Control" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
UE Service Pod Congestion Control: The UE service supports Pod Congestion Control mechanism that helps to handle heavy traffic of incoming requests. It considers every incoming request and decides to either reject or accept it based on a defined request priority and the status of service congestion level. For more information, see the "UE Service Pod Congestion Control" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Support for Diameter Message Response Time Latency Metrics: The support for timer latency metrics in Diameter Gateway service provides the time taken to service a request/response in Diameter call flows. This ensures that the cnPolicy meets the required service level agreements (SLAs) for latency as set by the Customer. For more information, see the "Support for Diameter Message Response Time Latency Metrics" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
PDS Performance Improvement: The PDS service supports Primary key based searches in its database. With this PDS service search speed and performance is significantly improved, thereby streamlining operations and improving user experience. For more information, see the "PDS Settings" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Support for cnDBTier APIs in CNC Console: The Policy CNC Console GUI supports integration of read only Georeplicaiton Recovery (GRR) cnDBTier APIs. With this users can have specific information on cnDBTier statuses on the CNC Console. For more information, see the "Support for cnDBTier APIs in CNC Console" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Traffic Segregation: Policy supports end-to-end traffic segregation based on traffic types. This ensures that critical networks are not cross-connected or share the same routes, thereby preventing network congestion. For more information, see the "Traffic Segregation" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Stale request cleanup for PCRF-Core service: Policy supports identifying and removing stale requests from Diameter Gateway, PDS, PRE or Usage Monitoring to PCRF Core. PCRF Core stops further processing of such stale requests and responses and sends a 13002 (DIAMETER_ERROR_TIMED_OUT_REQUEST) error to Diameter Gateway. For more information, see the "Support for Stale Requests Cleanup" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Stale request cleanup for SM service: Policy supports identifying and removing stale requests from Ingress Gateway to SM service. SM service stops further processing of such stale requests and responses and sends a a 504 (Gateway Timeout) error to Ingress Gateway. For more information, see the" Support for Stale Requests Cleanup" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Signaling and DB access processing latency histogram metrics for PCRF-Core service: New histogram metrics on signaling and DB access processing latency are added to PCRF Core metrics. These new histogram metrics allow the monitoring of latency on PCRF-Core callflows such as, response to diameter requests, HTTP incoming and outgoing connections, and DB requests. For more information, see the "PCRF Core Metrics" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Signaling and DB access processing latency histogram metrics for PDS service: New histogram metrics on signaling and DB access processing latency are added to PolicyDS metrics. These new metrics allow to monitor latency distribution for the HTTP services inside PCF, Also, these metrics helps to get a variety of information which enable to easily track and disect the different flow passing through PDS and measuring their performance. This is helpful in debugging and tracking of the PDS flows. For more information, see the "PolicyDS Metrics" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Support for End-to-End Log Identifier across Policy Services: This feature allows to use a unique identifier to every log message, which can be used to identify the set of logs belonging to a given session across all Policy services. For more information, see the "Support for Unique Log Identifier Across Policy Services" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Enhancements to Pending transaction Gx: Policy has been enhanced to support configuration change for response timeout. For more information, see the "Pending Transactions on Gx Interface" in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Logging Support for Error Response in Policy: Policy sends error responses to consumer NFs due to some exceptions, such as signaling, validations, and internal errors. These error responses have payloads containing the problem title, status, details, and cause of the error that are used to investigate the error. Policy has been enhanced to support logs for the error responses. For more information about this feature, see the "Logging Support for Error Response in Policy" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
Support for TLS: Policy supports TLS 1.3 for all functions and interfaces that are supported by TLS 1.2. With this feature, Policy supports the creation of TLS 1.3 and TLS 1.2 connections and mandatory ciphers and extensions. Moreover, Policy uses Diameter Gateway to establish secured connections with consumer NFs and producer NFs, respectively. These communication protocols are encrypted using Transport Layer Security (TLS). For more information, see the "Support for TLS" section in Oracle Communications Cloud Native Core, Converged Policy User Guide.
