What is SEPP?
SEPP is a network function designed to protect messages exchanged between different 5G networks (home and visited networks during roaming, for instance). It acts as a security gateway that filters and secures cross-border signalling traffic between network operators.
5G NR is the foundational technology for the fifth-generation cellular network, offering unprecedented improvements over previous generations. It dramatically increases speeds and capacity, enabling faster internet and supporting more users simultaneously. With ultra-low latency, 5G NR enhances real-time applications like augmented reality and autonomous driving. It operates across various frequency bands, providing flexibility and wider coverage. Key features include advanced network slicing for tailored services and significant improvements in energy efficiency. This technology is not just a leap in mobile connectivity; it’s a gateway to innovative applications and services, shaping the future of digital communication.
NR & LTE implements PDCP in both the User Plane and Control Plane. This is unlike UMTS, where PDCP was only found in the User Plane. The main reason for the difference is that PDCP in NR & LTE takes on the role of security, i.e. encryption and integrity.
Find Your Focus Dynamic Spectrum Sharing (DSS) allows operating LTE and NR networks in the same frequency bands. Dynamic Spectrum Sharing (DSS) is useful to allow operators to perform a soft refarming of the LTE spectrum towards NR. For Dynamic Spectrum Sharing support between LTE and NR in TDD bands. Some operators do not possess…
Medium Access Control (MAC) protocol specification written in (3GPP TS 38.321). MAC is a protocol layer above the physical layer and below the RLC layer. The ‘Medium Access Control’ (MAC) layer receives both the user plane and control plane data from the set of logical channels provided by the RLC layer. Multiplexes and…
