The Security Transition from 4G EPC to 5GC
March 19, 2024

If you look at how security was addressed in the 4G core (EPC), you had perimeter devices, whether it’s firewalls, security devices that protect from denial of service attacks, or just security gateways at the periphery, and you had fewer vendors addressing the core infrastructure. So, if you have a single core vendor, the risk […]

5G Core Network Functions (NFs)
October 28, 2023

The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make […]

What is Access Gateway Function (AGF)?
July 20, 2023

5G delivers higher data speeds, and lower latency, and supports more users, devices, and services while simultaneously improving network efficiency. As defined by the Third-Generation Partnership Project (3GPP), the 5G core (5GC) network is a cloud-aligned, service-based architecture (SBA) and covers all 5G functions and interactions. The converged 5GC lays the foundation for a single […]

What is the difference between EPC,EPC+ and 5GC?
July 24, 2021

The core network is the most important domain in the mobile network starting from 2G and 3G while the MSC and SGSN are the main functions there to EPC or Evolved packet Core, then EPC+ in 4G network and finally 5GC or 5G Core in 5G Network. However, there are many differences between EPC, EPC+, […]

What does 5G Cloud Native means?
June 24, 2021

What is Cloud Native? In general, “cloud-native” is an approach to building and running applications that exploit the advantages of the cloud computing model. One key attribute of “cloud-native” is how the system creates and deploys applications. According to the definition of CNCF, “cloud-native” means that an application is containerized and uses an open-source software […]
