Industry’s First-To-Market 3GPP R15 Compliant 5G Software Suite

Open telecom solutions provider, Radisys, has introduced industry’s first-to-market 5G Software Suite focusing on NodeB (gNB), 5G User Equipment (UE) and 5G Core Network (CN).

The 3GPP Release 15 compliant gNB provides support for mmWave and sub 6 GHz frequencies. Pre-validated with Intel’s FlexRAN 5G reference platform based on both Intel Architecture and Intel FPGAs, Radisys’ 5G Software Suite delivers support for Non-Standalone Mode (NSA), providing an easy migration path from LTE/LTE-Advanced deployments to 5G. The software suite is currently part of a Tier 1 Service Provider 5G trial in North America.


  • Service Providers globally are accelerating the move to 5G to accommodate the growing demands of new applications and services requiring ultra-low latency and extremely high speeds. Central to the initial implementation of 5G rollouts is the need for a seamless migration path from LTE/LTE-A and multi-access – mobile and fixed wireless.
  • The Radisys 5G Software Suite enables service providers to grow their 5G services while leveraging existing 4G LTE Enhanced Packet Core (EPC) by supporting Non-Standalone Mode (NSA) using Options 3/3a/3x. It also expands offerings for LTE/LTE-A which are already available with NSA enhancements for existing networks. The release initially focuses on massive Multiple-input Multiple-output (MIMO) deployment scenarios.
  • The Software Suite supports both mmWave (focused primarily on Fixed Wireless Access) and sub6GHz (focused on Mobile Access) frequencies for deployment flexibility; Centralized Unit (CU) and Distributed Unit (DU) split and CUPS (Control User Plane Separation) on F1 and E1 interfaces respectively to address rollout cost.

Key features of the Radisys 5G Software Suite include:

  • Full integration with the Intel FlexRAN 5G reference architecture which features Intel architecture and Intel FPGAs
  • Support for Centralized Unit (CU) and Distributed Unit (DU) supporting 3GPP F1 interface
  • Support for Control Plane (CP) and User Plane (UP) using CUPS (Control User Plane Separation) supporting 3GPP E1 interface
  • Also available are solutions for 5G UE as well as 5G CN (Core Network) with components such as Access and Mobility Management Function (AMF), Session Management Function (SMF) and User Plane Function (UPF) supporting P4 scripting and Internet Locator Addressing (ILA)
