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.

Find Your Focus O-RAN Architecture Principle The O-RAN architecture and interface specifications shall be consistent with the 3GPP architecture and interface specifications to the extent possible. The architecture shows that the four key interfaces – namely, A1, O1, Open Fronthaul M-plane & O2– connect SMO (Service Management and Orchestration)framework to O-RAN network functions and O-Cloud.
Find Your Focus ControlResourceSet What is Coreset? How CORESET work in 5G A control resource set (CORESET) is defined as a set of REGs under given numerology (i.e., subcarrier spacing) , Particularly, in the frequency domain, a CORESET is a set of contiguous or distributed physical resource blocks (PRBs) configured using a 6-PRB granularity, within
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
VOLTE COVERAGE IMPROVEMENT Optimization Feature TTI Bundling TTI bundling is specified in 3GPP (TS 36.213, 36.321) to allow the improved uplink performance for cell border UEs (which often hit the maximum transmission power) and for reduced PDCCH load.
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.
