In a constantly evolving technological environment, telecom operators must anticipate innovations and modernize their infrastructures to optimize their services. Sofrecom recently assisted a major player in the sector in successfully executing a network engineering and architecture project. This project aimed to support the evolution of mobile technologies, particularly 4G telephony (VoLTE), while ensuring an optimal user experience.
Customer need: modernize and optimize the core network
Faced with a growing demand for connectivity and advanced services, the client aimed to modernize its core network infrastructure, particularly in 4G telephony (VoLTE). The challenges were multiple:
- Support subscriber growth: increase from 2 million to 18 million VoLTE subscribers.
- Deploy new services: conference calls, announcements, VoLTE roaming, and more.
- Ensure performance and reliability: anticipate capacity needs, resolve critical incidents, and optimize equipment.
- Comply with international standards: align with 3GPP standards to ensure interoperability and compliance.
This project required advanced technical expertise, a rigorous methodology, and the ability to collaborate with internal teams and suppliers.
Tailored support and cross-functional expertise for the client
To meet these needs, Sofrecom deployed a proven methodology focused on technical expertise, collaboration, and innovation. Here are the key steps of our approach:
- Analysis and planning: an in-depth analysis of the client's needs, technical constraints, and objectives allowed us to define a clear roadmap, including architecture studies, technology choices, and deployment steps.
- Design and deployment: utilizing tools such as High-Level Design (HLD) and Low-Level Design (LLD), our experts designed solutions tailored to the client's specific needs. Deployment was carried out with a focus on timelines and quality standards, ensuring seamless integration into the existing infrastructure.
- Collaboration with stakeholders: Sofrecom ensured smooth communication between the client's internal teams, suppliers, and other stakeholders. This collaboration included order management, equipment validation, and rapid incident resolution, ensuring operational continuity.
- Continuous optimization: throughout the project, we implemented optimization processes to ensure network performance. This included monitoring KPIs, managing licenses, preparing updates, and estimating future needs.
- Knowledge transfer: finally, Sofrecom ensured the transfer of expertise to the client's teams by documenting procedures and providing technical support as needed. This knowledge transfer enabled employees to adopt tools and best practices, ensuring the sustainability of the implemented solutions.
A High-Performance and scalable infrastructure established
Thanks to Sofrecom's support, the client achieved its strategic objectives and strengthened its position in the telecommunications market. Here are the main benefits obtained:
