| SD-Core 1.3 Release |
| =================== |
| |
| 1.3.0 Release Details |
| --------------------- |
| |
| SD-Core supports 4G & 5G network functions and includes APIs for configuration, telemetry, |
| policy management. Access networks can connect to Access & Mobility Management Function (AMF) |
| or Mobility Management Entity (MME) depending on the type of access used. Below is the summary |
| of the features delivered in SD-Core 1.3 Release. |
| |
| Highlights |
| ---------- |
| |
| Release v1.3.0 focuses on stabilizing Cloud Native support to 5G network functions and adding Metrics support. |
| Also, towards greater adoption by community members, many members used SD-Core to tests against real |
| hardware gNodeB and phones. |
| All new functionality in this release contributes to support of 5G Network functionality. |
| |
| |
| **Real gNodeB & real UE Tests**: Multiple community members mentioned success with SD-Core being used against |
| real UE & gNB. To name the few, CPQD(Brazil), ONF, Pronto project for DARPA, etc. ONF used gNodeB from Sercomm and |
| while the real phones were Google Pixel and Moto5G. |
| |
| We also enhanced 5G core to support the test IMSI(the one having mcc/mnc as leading zeroes) for development testing. |
| |
| **5G Metric Dashboard**: A new NF, Metric Function has been added to provision 5G Cloud Native metrics. |
| The Metric Function acts as both metrics aggregator and processor towards metric consumers like Analytics Engine, |
| API Server or Prometheus Server. |
| |
| The 5G Metric dashboard shows whether the gNodeB and UPF are connected to the core, how many active UEs are connected, |
| including UE’s IMSI and Slice information, and the uplink (Tx Bitrate) and downlink (Rx Bitrate) throughput at the UPF. |
| Metrics work can be extended to show various metrics from 5G core network. |
| |
| **NRF Cache and Notification**: As part of NF Discovery Service, Each NF discovers Target NF for its profiles from NRF |
| and stores Target NF profiles in a local cache. One cache is created per Target NF Type to make the lookup faster. |
| |
| The NF creates subscription for the NF profiles received from the NRF. When a notification is received from the NRF |
| on profile Deregistration, the entry is evicted from the local cache. This will trigger the host NF to perform |
| requested NF Discovery during the next UE procedure. |
| |
| **Test IMSI Support**: This support allows users to employ Test UEs with leading zeroes(mcc/mnc with leading zeroes) |
| with SD-Core 5G. This eliminates the conflict with commercial PLMNs during UE attach. |
| |
| **Static UE IP-Address Support**: The SMF shall support allocation of static IP-address to UE. This feature shall be |
| available via configuration of SUPI to IP-address mapping under SMF specific section via override values file. |
| |
| **Dynamic Subscription revoking provision**: This feature enables 5G network to revoke subscription of specific UE. |
| It is required that user identifies the IP-Address of specific UE to be disabled. The custom user application can |
| make available the IP-Address of specific UE to 5G core network via Metric-Function API. The 5G network shall revoke |
| the specific UE’s subscription based on UE IP-Addresses received. |
| |
| **Multiple gNBs Support in gNBSim**: This enhancement allows deploying multiple gNBSim instances. This would extend |
| gNBSim capabilities towards XN and N2 handover procedures. |
| |
| **Inter-op stabilisation across multiple instances of SMF and AMF**: Enhancements have been done around stabilisation |
| of multiple instances of SMF and AMF inter-operation. This adds robustness towards cloud native stateless and |
| high-availability feature. |
| |
| **Autoscaling of AMF/SMF instances in AIAB using KEDA**: It enables dynamic scaling of network functions to handle |
| increased traffic or workload demands, ensuring optimal performance and cost-effectiveness. |
| Kubernetes Event-driven Autoscaling (KEDA) is an open-source tool that makes it easier to implement autoscaling for |
| cloud-native network functions(https://github.com/kedacore/keda). |
| |
| **Minor Enhancements**: |
| |
| - Update Subscriber Context in DB after the Handover Procedure is completed. |
| - Multiple instances of Sctp-lb could run but this should be done manually. |
| |
| Known Limitations: |
| -------------------- |
| |
| - Only one instance of the UPF-adapter pod should be deployed. |
| |
| - Scale up or down instances of AMF/SMF/Sctp-Lb can be done manually. |
| |
| - If webui pod is restarted and if callback configuration is not provided in webui pod then simapp does |
| not download the config again to webui. Restarting the simapp pod solves the problem most of the time. |
| |
| - UPF Pod needs to have UE pool configuration and UPF does not use UE IP Pool configuration from Slice APIs. |
