OSTV Network Management System
OSTV Network Management System (NMS) is an integrated platform

designed to deploy large scale Virtual Radio Access Networks (VRAN)
based on Amarisoft LTE/NR stack. It is based on SlapOS open sourceedge computing platform that has been deployed successfully since2009 in companies such as Airbus, Mitsubishi, SANEF, Kyorin, etc.

The core function of OSTV NMS is to provision and monitor acomplete Virtual Radio Access Network across tens of thousands ofgeographical sites. This includes automated setup of autonomous basestation, automated provisioning of eNodeB, automated software

upgrade, interfacing to central core network, automated packet routing,network

healthmonitoring,predictivemaintenance,

subscriber

database management, accounting and billing. All NMS functions canbe accessed through a central dashboard based on a geographical map
withalarms that turn fromprediction) and red (incident).

green (OK)to orange (incidentIssue Tracking Workflow
Each time an alarm turns orange or red, or whenever a subscriber

complains, OSTV NMS generates a ticket and initiates a workﬂow totrack the issue through its different states until it is resolved. Network

management staff analyses and identiﬁes the issue through graphicalmonitoring tools that let them dig into possible causes. Each

resolved issue is categorised and feeds machine learning (A.I.) models
that provide predictive notiﬁcation to prevent similar issue to happen
again in the future.

OSTV NMS can automatically provision each base station with all kindsof value added networking services. A Content Delivery Network (CDN)
can be deployed to accelerate https/QUIC protocols and reduce latency.

An IoT gateway can be deployed to buffer data sent through MQTT

protocol by nearby NB-IoT compatible device. A local subscriber
database can be deployed to ensure resilient network operation in caseof disaster.

SDK + REST API
A Software Development Kit (SDK) is provided with OSTV NMS

platform to let telecommunication companies develop their own value
added services, custom monitoring or custom radio deployment. OSTVNMS also provides a complete REST API to remotely control any of its
features and simplify system integration.
