Scalable Service Communication Proxy
for 5G Core

The Service Communication Proxy (SCP-5G) simplifies 5G core network architectures by aggregating, routing, and load-balancing HTTP/2 signaling traffic between Network Functions, reducing complexity while improving scalability and operational control.

By acting as a centralized communication layer, the SCP-5G enhances security and governance across the 5G core. It supports TLS up to version 1.3, Network Function service authorization, and provides controlled entry and exit points for NF clusters, helping operators enforce consistent security policies.

PAiCore SCP-5G enables efficient interaction between Network Functions through native integration with the Network Repository Function (NRF), supporting service discovery, subscriptions, and notifications in line with 3GPP specifications.

Designed for cloud-native environments, PAiCore SCP-5G optimizes signaling performance and elasticity in modern deployments, with support for Docker and Kubernetes. When required, it can also interwork with existing legacy signaling environments, enabling a smooth evolution from previous network generations.
