Unlock Flexibility and Cost Savings: How Service Providers Can Scale with a Pay‑as‑You‑Grow Virtual Packet Core

Over the past decade, virtualisation has been touted as the key to reducing capital spend, simplifying network management, and delivering the high‑quality experience (QoE) that 4G‑connected users demand. Yet, many operators still struggle to realise these benefits in practice.

Alistair Grant, Business Development EMEA at Adax, asks: Are service providers truly reaping the rewards of virtualisation, or are they merely chasing buzzwords? The answer lies in adopting a Virtual Packet Core (VPC) that marries agility with performance.

A recent industry survey revealed that 23.3% of service providers cite network/service agility as the biggest barrier to IoT adoption, while 14% fear performance and reliability impacts. A VPC – a framework that virtualises core functions for 4G/LTE networks – directly addresses these concerns by separating control and data planes and enabling modular deployment.

The Distributed Packet Core (DPC) further refines this model by distributing core elements such as PGW, SGW, MME, and HSS across the network as demand dictates. Together, VPC and DPC deliver reduced CapEx and OpEx, heightened reliability, and unprecedented agility.

Mobile Virtual Network Operators (MVNOs) exemplify the transformative power of VPC. By deploying their own modular core, they avoid costly hardware leases and gain a single, centrally‑managed control plane. This scalability allows them to tailor services precisely to each customer’s needs.

Key attributes of an effective VPC solution include:

• Pre‑separated control and data planes
• Modular core components that can be deployed independently
• Scalability that supports IoT, MVNOs, and WiMax replacement use‑cases
• A pay‑as‑you‑grow pricing model that aligns cost with actual demand

In today’s fast‑moving telecom landscape, operators who embrace VPC stand to realise significant cost savings, improved performance, and a superior user experience. The modular architecture is versatile enough to adapt to diverse deployment scenarios, making it an ideal foundation for next‑generation LTE networks.
