LTE and 5G Core

In recent years, a range of industries and enterprises has begun deploying custom-designed private cellular networks, which we term community cellular networks (CCNs). Decentralizing these networks could potentially empower the local community, increasing opportunities and freedom. For example, the Citizens Broadband Radio Service (CBRS) in the shared 3.5GHz band supports independent indoor and outdoor cellular networks. Imagine that several private LTE networks operating in a single building, neighborhood or campus. Similarly, LTE networks in unlicensed spectrum such as LTE-U and LAA are also gaining more attention. With this emerging trend, the desirable cellular core network needs to provide flexibility, scalability and robustness coordinating multiple independent cellular network entities in the community such that users can enjoy seamless, reliable, and efficient communication across these networks is of paramount importance.

NetworkView is developing software solutions for LTE/5G/NB-IoT core network entities. Our solutions are not only fully compliant with the latest 3GPP specifications, but also they are extended to include a set of further functionalities such as s1/x2 aggregation, proxying, local breakout, etc.

Flexibility – Our portable software-based implementation is versatile in any type of hosting environment. 

Scalability – Capacity is easily increased by adding more software instances.

Robustness – Our solution supports all 3GPP standard-based reliability features (e.g, S1-flex) as well as our proprietary failover technique which provides seamless service to users. 

Network Elements – Galaxy IMS/PS/CS/HSS

  • CS services:
    • Call service:
      • call barring, call forwarding, color ringtone, roaming
      • –        ported number
      • sms, mms, ussd
  • PS service:
    • ALL-PS, ROAM, HPLMN-AP, VPLMN-AP
    • QoS
    • PDP context for data
    • PGW (internet data)
  • IMS service:
    • IMS private and public identities (per subscriber)
    • SIP username, authentication, realm (per subscriber)
    • Domain and CSCF configuration (per profile)
    • Initial Filter Criteria (per profile)
  • HSS
  • Galaxy offers a complete solution through our HSS/HLR. Our HSS/HLR solution is ideally suited for MNO, MVNO/MVNE and M2M market. It is designed to overcome the limitations and disadvantages of traditional HSS products regarding flexibility, virtualization, cost of scaling and vendor lock-in.
