5G Service Communications Proxy (SCP)

NetNumber Integrated Service Communication Proxy (SCP)

The Service Communication Proxy (SCP) is one of the most important elements of the 3GPP Service-Based Architecture (SBA) for 5G Core networks. The SCP is functionality similar to the Diameter Routing Agent (DRA) in 4G, functioning as a central control point in the signaling network core.

The SCP performs multiple key functions, simplifying core network routing topology & offloading the Network Repository Function (NRF) from service discovery, thus enabling greater 5G core network geo-distributed scalability.  Key functions include:

  • Message routing, load balancing & distribution
  • Traffic prioritization & overload handling
  • 5G Service Delegated Discovery
  • Optional message manipulation & transformation
Feature Highlights

For two decades, NetNumber has been a leader in fixed and mobile signaling, routing and security. Key 5G SCP capabilities include:

  • 5G Consumer-Producer Secure Communications 
  • 5G Consumer-Producer Binding 
  • High Performance HTTP/2 Signaling Stack 
  • HTTP Proxy Support 
  • Delegated Discovery / Discovery Caching 
  • Multi-Service & Multi-Slice Support 
  • Programmable Dissector-based Rules Engine 
  • Dynamic Flexible Routing / Load-Balancing 
  • Rate Limiting & Overload Protection 
  • Rich Monitoring & Observability framework (Tracing, KPIs & TDRs)  
  • Interworking & Message Transformation (optional) 
  • NetNumber TITAN.IUM Traffic Analytics (optional) 

Key 5G SCP benefits include:

  • Central element of the 5G Core service-based signaling network providing secure message routing, load-balancing, overload protection & traffic visibility.
  • Greatly reduces the complexity of managing large geo-distributed 5G Core signaling networks.
  • Incorporates powerful award-winning Dissector-based Rules Engine enabling flexible customer programmability.
  • Part of the TITAN.IUM InterGENerationalTM Cloud-Native Framework interworking HTTP2, DIAMETER, SIP & SS7 signaling.
  • “Deploy anywhere” installation on premises or in the cloud via Containers, Virtual Machines or Bare Metal.
