EPC

Summa Networks EPC is a complete 4G core — mobility management (MME), gateways (SGW, PGW), subscriber data (HSS), and policy and charging (PCRF) all included — built for 5G-EPC interworking. Each function is also available on its own (HSS as Summa Networks SDM, PCRF as Policy Function), and IMS (P-CSCF, I-CSCF, S-CSCF, TAS and more) combines with EPC when you need voice and multimedia.

Overview

A Modular 4G Core That Evolves With Your Network

Summa Networks EPC provides the core network functions required to operate and manage 4G/LTE networks — from mobility management and session routing to external data connectivity. Designed for interoperability with 5G, it lets operators evolve progressively, protecting existing investments and maintaining service continuity.

Connected to the same Extended and Converged Control Plane that powers the rest of Summa Networks’ portfolio, EPC enables true interworking between 4G and 5G network functions. It covers mobility, gateways, subscriber data and policy control by default — and combines with Summa Networks IMS Core when you need voice and multimedia, too.

  • Covers MME, SGW, PGW, HSS and PCRF by default; combine with IMS Core when you need voice and multimedia
  • 5G-EPC interworking, built on the same standards-based approach used across Summa Networks’ portfolio
  • Self-paced 5G evolution — activate 5G functions when ready
  • Future-proof investment with no vendor lock-in
  • Connects up to Summa Networks’ Extended and Converged Control Plane

Architecture

Where EPC Sits in Summa Networks’ Architecture

Elements of Summa Networks' Full Core - Converged Control Plane

Simplified view — for the complete architecture, see Full Core.

EPC sits in Summa Networks’ Convergent User Plane, alongside PGW, and connects up to the Extended and Converged Control Plane — see the Full Core page for how it fits with the rest of the architecture. IMS (P-CSCF, I-CSCF, S-CSCF, TAS and more) is covered by Summa Networks IMS Core and combines with EPC for voice and multimedia.

Features

Built for how operators actually work

A modular function set covering mobility management and gateway routing for 4G — from a lightweight standalone deployment to a full core combined with the rest of Summa Networks’ portfolio.

Modular and combinable

Covers MME, SGW, PGW, HSS and PCRF by default. Combine with Summa Networks IMS Core when you need voice and multimedia, too.

Built for 5G-EPC interworking

Designed to interwork with 5G-EPC, so operators run 4G and 5G side by side instead of forcing a disruptive migration.

Carrier-grade and cost-efficient

Software-based architecture optimizes the use of hardware resources without compromising performance.

Self-paced 5G evolution

Choose when and how to move toward 5G Standalone — on your own timeline, not a vendor’s roadmap.

Use cases & market segments

Who deploys Summa Networks EPC

MNOs modernizing LTE

Extending or modernizing LTE coverage without a rip-and-replace core migration.

MVNOs becoming full MVNO

Owning a complete 4G core with EPC — mobility, gateways, subscriber data and policy included — and adding IMS Core when voice services are needed.

5G NSA & SA evolution

Transitioning from 4G to 5G NSA and evolving toward 5G SA at their own pace.

IoT & Private LTE

Requiring a dedicated, right-sized user-plane core.

Legacy core replacement

Replacing legacy or high-risk vendor infrastructure with a standards-based, modular alternative.

Business model

Priced for how your network grows

Summa Networks EPC is priced based on active subscribers — CAPEX, OPEX or PAYG — consistent with the rest of Summa Networks’ portfolio. Cost scales with your network, not with a fixed module count.
