NMS / OSS Network

Network Management Systems (NMS) and Operational Support Systems (OSS) form the operational backbone of any telecommunications network. They provide operators with unified visibility, control and automation across the full network lifecycle from fault detection and performance monitoring to configuration management and service fulfilment.

As networks grow in complexity incorporating 5G RAN, virtualised core, disaggregated transport and cloud-native functions the demands placed on NMS/OSS platforms have never been greater. WillowTech's team of specialists supports operators in deploying, integrating and optimising these systems to ensure continuous, reliable network operations.

NMS / OSS capabilities

Our NMS/OSS practice covers the full FCAPS model and extends into modern service orchestration, enabling operators to manage today's complex, heterogeneous networks effectively:

Fault management & alarm correlation

Configuration & change management

Network inventory & topology

Multi-vendor element management

Performance management & KPI analytics

Service order & fulfilment

SLA monitoring & assurance

OSS/BSS integration
