MiniCore 5G

A full 5G, LTE/IMS and GSM/GPRS Core Network for tests and research

MiniCore is a Software-defined compact Core Network that can be used as a test 5G network, LTE/IMS or GSM/GPRS Core Network.

It combines our YateHSS/HLR (AUSF/UDM), YateUCN (SMF/UPF) and YateNRF in a small package for full functionality of all generation network technologies.

This cost-effective solution serves the needs of both mobile network operators and virtual network operators that aim to implement the 5G technology.

MiniCore 5G provides full access to the following Core Network technologies:

  • 5G
  • IMS


The MiniCore is a small factor PC computer that has preinstalled the following software components:

  • YateHLR/HSS (NSSF, AUSF, UDM, AuC, HLR, HSS, Subscriber management)
  • YateNRF (registration and discovery of 5G CAPIF services by various parameters)
  • YateSMSC (SMS store-and-forward, routing, home routed SMS)
  • YateSTP (routing of SS7 messages by Point Code or Global Title)
  • YateDRA (routing of Diameter messages by host, realm, application)
  • YateMMI (Web management interface)

NOTE: On demand additional components can be installed on the same hardware.

5G testing


  • Setup/edit mobile network and component preferences via MMI management interface
  • Minimal monitoring of each network component, additional YateBTS monitoring possible
  • Wireshark capture of communication between components including decrypted IMS traffic
  • JSON API integration with any SIM management and CRM systems
  • JSON and REST API for sending SMS
  • Can use 5G CAPIF, SIGTRAN/SS7 and Diameter for signaling
  • Supports IPv4, IPv6 and Non-IP
  • Works both stand alone and with external components
