What is BSS/OSS transformation and why does it matter?

BSS (Business Support Systems) and OSS (Operations Support Systems) are the core platforms that manage billing, customer management, and network operations for telecoms. Modernising these systems enables operators to launch new services faster, reduce operational costs, and improve customer experience.

How does Portamus approach telecom EA assessments?

We assess the current BSS/OSS architecture, network function landscape, and digital service delivery capabilities, then define a phased target architecture using TOGAF ADM aligned to the operator's business strategy and market positioning.

Can you design an API marketplace for a telecom operator?

Yes. We design API platform architecture following TM Forum Open API standards, covering API gateway design, developer portal, partner onboarding processes, and monetisation models.

What is your experience with 5G network architecture?

We support 5G architecture design including core network (5GC) integration, network slicing strategy, cloud-native network function (CNF) deployment patterns, and enterprise 5G use case architecture.

How do you support customer experience transformation in telecoms?

We design the integration architecture connecting CRM, self-service platforms, and digital channels with BSS/OSS systems, enabling personalised customer journeys, real-time service activation, and unified customer data across all touchpoints.

BSS/OSS transformation, API-first architecture, and platform modernisation for telecom operators.

Industry Overview

The Telecommunications Landscape

About This Industry

Telecommunications operators face mounting pressure to modernise BSS/OSS platforms, adopt API-first architectures, and build scalable digital services as 5G, IoT, and cloud-native delivery models reshape the industry landscape.

Why Architecture Matters

Legacy OSS/BSS stacks create integration bottlenecks, limit product agility, and increase time-to-market for new digital services. A structured EA approach enables telecom operators to modernise incrementally while maintaining service continuity.

The Portamus Difference

Portamus supports telecom operators and network providers in evolving OSS/BSS estates, network platforms and customer systems toward cloud and 5G. With TOGAF® method and ITIL® expertise, our senior architects modernise complex, high-availability telecom architectures and standardise integration across the estate.

How we help Telecommunications organisations

Telecom operators run OSS/BSS estates, network platforms and customer systems that must evolve toward cloud and 5G. We design telecom architectures that modernise OSS/BSS, standardise integration and bring ITIL-based service management to complex, high-availability environments.

We typically begin with a focused architecture maturity assessment and expand into EA Assessment and ITSM Implementation as priorities become clear.
