Release 22.4.1
No new features or feature enhancements have been introduced in this release.
Release 22.4.0
- Network Separation for Egress Requests: In previous OCCNE releases, all requests generated by an application running on OCCNE contained the source IP of the Kubernetes worker node on which the application pod was running and all Kubernetes worker nodes got their IP addresses from the same external network. Therefore, all external requests coming from OCCNE had a source IP of that network. This was confusing as the requests arriving at a server outside of OCCNE appeared to be sent from a network other than the one that hosted the server. Also, the security policies in the customer's networking infrastructure blocked these requests. In this release, OCCNE allows an application to select a specific external network and uses an IP address from that network as the source IP field for its egress requests.
- Private IPs for Kubernetes Worker Nodes: In previous OCCNE releases, all requests generated by an application running on OCCNE contained the source IP of the Kubernetes worker node on which the application pod was running. This exposed the Kubernetes worker nodes to external access which was a potential security concern. It also required a potentially large number of public IPs to deploy OCCNE. In this release, Kubernetes worker nodes are given IP addresses on the OCCNE internal network. As a result, Kubernetes worker nodes are no longer accessible outside of OCCNE, thereby reducing the attack surface of OCCNE. Also, the number of public IPs required to deploy OCCNE has been significantly reduced.
- Bastion Host High Availability: With this release, OCCNE automatically selects an active Bastion Host when the current active Bastion Host fails. Additionally, Bastion Host synchronizes all repositories that includes binary files, container images, Yum packages, and Helm charts. This ensures that when nodes in the Kubernetes cluster need to load container images or Helm charts from the Docker, and Helm repositories hosted on the Bastion Hosts, they get the same images and charts, regardless of which Bastion Host is active.
- Supports New Version of Common Services: CNE is compatible with
the following common services versions:
- Helm - 3.8.2
- Kubernetes - 1.23.7
- containerd - 1.6.4
- Calico - 3.22.3
- MetalLB - 0.12.1
- Prometheus - 2.36.1
- Grafana - 7.5.11

For more information, see Overload Control based on Percentage Discards in OCNSSF Supported Features chapter of Oracle Communications Cloud Native Core Network Slice Selection Function User Guide.
- Support for Autopopulation of Configuration Using NRF Content: Currently, NSSF requires the operator to maintain AMF set data manually in the database, which it uses while responding to initial registration query during the subscription request. This enhancement removes the need for manual configuration by allowing NSSF to autoconfigure AMF information using NRF (Network Repository Function) whenever there is an update in the AMF Set data. For more information, see Autopopulation of Configuration Using NRF Content in OCNSSF Supported Features chapter of Oracle Communications Cloud Native Core Network Slice Selection Function User Guide.
- Support for OAuth Access Token Based Authorization Using Key-ID and NRF Instance ID: Before this enhancement, NSSF used NRF Instance ID to validate the access token, where Ingress Gateway stored public keys against NRF instance Id. This enhancement allows NSSF to use multiple public certificates for validating Access tokens by adding support for Key-ID (K-ID) based access token validation, in addition to the existing NRF Instance ID based access token validation. For more information, see OAuth Access Token Based Authorization in OCNSSF Supported Features chapter of Oracle Communications Cloud Native Core Network Slice Selection Function User Guide.

- Concurrency Handling for PCRF-Core using Bulwark Service: PCRF-core supports the Bulwark service to handle the concurrent messages on Gx interface. PCRF-core interacts with Bulwark service using lock and unlock message exchanges by acquiring and releasing the User-IDs based lock upon receiving CCR-I/U/T messages. For more details, see "Support for Concurrency Handling using Bulwark Service in PCRF" section in Oracle Communications Cloud Native Core Policy User Guide.
- Concurrency Handling for SM Service using Bulwark Service: CNC Policy supports the Bulwark service to handle the concurrent requests coming from other Policy services. The Bulwark service integrates with the SM service to handle the concurrent requests for the SM update-notify procedures. The SM service integration with Bulwark service handles the concurrent requests for the same subscriber in a concurrent and efficient manner. For more details, see "Support for Concurrency Handling using Bulwark Service" in Oracle Communications Cloud Native Core Policy User Guide.
- Handling Concurrent Notification Requests for PDS Service: When PDS receives concurrent notification requests for a subscriber (same SUPI) of the same data source, processing multiple notification requests at the same time can result in inaccurate data. To avoid this issue, PDS is integrated with Bulwark Service. Bulwark Service provides lock and unlock mechanism over a SUPI or GPSI key and allows processing of only one notification at a time. For more details, see "Support for Concurrency Handling using Bulwark Service" in Policy section in Oracle Communications Cloud Native Core Policy User Guide.
- Integration with NWDAF: CNC Policy 22.4.0 includes phase one implementation of CNC Policy integration with NWDAF for testing purposes. This integration helps to get analytics information, which PCF consumes to make policy decisions. For more details, see "NWDAF Agent" section in Oracle Communications Cloud Native Core Policy User Guide.
- Timer Profile in Binding Service: CNC Policy applies the specific timeout profile while sending request to external NFs. In this release, PCF Binding Service has been updated for BSF. For more details, see "Timer Profiles" section in Oracle Communications Cloud Native Core Policy User Guide.
- Delete Individual URSP Rule For Fragmented Delivery: CNC Policy is enhanced to support UE service with deletion of URSP rule(s) in subsequent call flows that were previously sent over N1N2 NAS message delivery. For more details, see "UE Policy Enhancements" section in Oracle Communications Cloud Native Core Policy User Guide.
- Support for T3501 Timer Implementation: CNC Policy supports T3501 Timer for UE policy. For more details, see "PCF UE Policy Service" section in Oracle Communications Cloud Native Core Policy User Guide.
- Database Optimization for the Performance Improvements: When using a replication setup that involves different sources, it is possible that the same row in a replica is updated by different sources. Conflict resolution in NDB cluster replication resolves such resolution conflicts by providing a user-defined conflict resolution column, which is used to determine whether an update from a source can be applied to the replica or not. Searching the Database for PDSProfile record was time consuming. The PDS search query is optimized by user by selecting the search index in order of preference in CM GUI.
- Support for Spending Limit Status Reporting: CNC Policy provides an option to enable spending limit status in each of the create, update, and delete requests from the Policy Services (SM Service, AM Service, and UE Policy Service). The Spending Limit control enables the Policy services to retrieve policy counter status information per subscriber from CHF. That is, by subscribing to spending limit reporting (CHF Data), Policy services can receive notifications on Policy Counters from CHF. For more details, see "Support for Spending Limit Status Reporting" section in Oracle Communications Cloud Native Core Policy User Guide.
- Support for Usage Monitoring in Session Viewer: CNC Policy now allows viewing the session details for Usage Monitoring service through CNC Console. For more details, see "Session Viewer" section in Oracle Communications Cloud Native Core Policy User Guide.

- SEPP Message Feed Feature: This feature allows SEPP to report every incoming and
outgoing message onto "Data Director" using the Ingress and Egress Gateways. This would
enable SEPP to perform the following activities:
- Lawful Interception
- Call Tracing/Tracking
- Debugging
Data Director receives the messages from Gateways with a correlation-id and feeds the data securely to an external monitoring system.

- OSO Integration: OSO is integrated with SEPP services. OCSEPP supports OSO 22.3.x for common operation services (Prometheus and components such as alertmanager, pushgateway) on a Kubernetes cluster which does not have these common services. For more information on OSO installation procedure, see Oracle Communications Cloud Native Core Operations Services Overlay Installation Guide.
- Supports Integration with Aspen Service Mesh: SEPP leverages the Platform Service
Mesh (for example, Aspen Service Mesh) for all the internal and external TLS
communication. The service mesh integration provides inter-NF communication and allows API
gateway to co-work with service mesh. The service mesh integration supports the services
by deploying a special sidecar proxy in each pod to intercept all network communication
between microservices. With this feature, all the SEPP services are leveraged to use ASM.
For more information on configuring ASM, see "Configuring OCSEPP to support ASM" section in Oracle Communications Cloud Native Core Security Edge Protection Proxy Installation and Upgrade Guide.
