OSTV Network Management System (NMS) is an integrated platform designed to deploy large scale Virtual Radio Access Networks (VRAN) based on Amarisoft LTE stack. It is based on SlapOS open source edge computing platform that has been deployed successfully since 2009 in companies such as Airbus, Mitsubishi, SANEF, Kyorin, etc.
The core function of OSTV NMS is to provision and monitor a complete Virtual Radio Access Network across tens of thousands of geographical sites. This includes automated setup of autonomous base station, automated provisioning of eNodeB, automated software upgrade, connectivity to central core network, automated packet routing, network health monitoring, predictive maintenance, subscriber database management, accounting and billing. All NMS functions can be accessed through a central dashboard based on a geographical map with alarms that turn from green (OK) to orange (incident prediction) and red (incident).
Each time an alarm turns orange, read or a subscriber complains, OSTV NMS generates a ticket and initiates a workflow to track the issue through its different states until it is resolved. Network management staff analyses and identifies the issue through graphical monitoring tools that let them dig into possible causes. Each resolved issue is categorized and feeds machine learning (A.I.) models that provide predictive notification to prevent similar issue to happen again in the future.
OSTV NMS already supports ultra low latency deployment typical of future 5G networks by deploying an optional local core network on each base station, next to the eNodeB. OSTV NMS nodes can form a completely decentralised hybrid mesh network. IPv6 based latency optimised routing algorithm powered by babel protocol (RFC 6126) ensures fastest possible eNodeB to eNodeB communication without having to route packets through a central office and distances over thousands of kilometers.
OSTV NMS can automatically provision each base station with all kinds of value added networking services. A Content Delivery Network (CDN) can be deployed to accelerate https protocol 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 case of disaster.
A Software Development Kit (SDK) is provided with OSTV NMS platform to let telecommunication companies develop their own value added services. OSTV NMS also provides a complete REST API to remotely control any of its features and simplify system integration.
