Caltta 5G Core Network

Based on a high-performance processing server and large-capacity software, Caltta 5G core network product(i5GC) is compliant with the 3GPP R16 standard. It can support all the necessary logical network elements of the 5GC network, including AMF, SMF, UPF, AUSF, UDM, PCF, NRF and NSSF. Caltta provides small and medium-sized 5GC solutions for enterprise 5G networks and small operator networks and supports in-depth customization according to customer needs.


Features of 5G Core Network

  • Advanced Architecture

  • Based on a self-developed lightweight platform, i5GC adopts cloud-native micro-service architecture, separation of computing and storage, and separate storage of static data and dynamic operation data. 

  • Standard Interface

  • Follows 3GPP R16 protocol; control plane and user plane interfaces are decoupled; supports interconnection with mainstream DMR manufacturer.

  • Flexible Networking

  • i5GC can be deployed on a universal server or on a virtual machine. The user plane provides normal and high-performance forwarding modes, meeting various networking requirements.

  • Evolution and Integration

  • Supports the smooth evolution from 4G to 5G, 4G-and-5G convergence, unified number allocation and unified network management.

  • High Performance and Reliability

  • The control plane supports 100,000 user capacity and 5000 BTSs. The 5G system supports multi-instance load sharing, active and standby storage of microservices, control plane and media plane 1+1 hot standby, and second-level recovery after downtime.

  • High Security

  • i5GC supports multiple security mechanisms: IPSec data encryption, user ID SUCI encryption and NAS full-protection encryption, anti-DDOS. And network management supports HTTPS, log audits, decentralized domains, etc.
