1.Introduction Cloud and Network Function Virtualization (NFV) for 5G networks represent a fundamental shift in how telecommunication networks are designed and managed. NFV decouples network functions from specialized hardware, allowing them to run as software on standard cloud infrastructure. This virtualization enables 5G networks to be more flexible, scalable, and cost-efficient by leveraging cloud-native principles and automation. It allows operators to dynamically alloca

1.      Introduction The RRC_INACTIVE state represents a fundamental architectural innovation in 5G New Radio (NR), introduced to address critical latency and signaling overhead challenges that plagued LTE networks. In LTE, frequent transitions between RRC_IDLE and RRC_CONNECTED states created substantial network signaling load and introduced latency penalties during service resumption, particularly problematic for modern smartphone usage patterns characterized by frequent sm

1) Introduction The 5G NR gNB split architecture divides the base station into functional entities — Central Unit (CU) , Distributed Unit (DU) , and Radio Unit (RU)  — to optimize deployment flexibility, scalability, and performance. This functional split enables c entralized control and distributed radio processing, allowing operators to balance latency-sensitive tasks at the edge (DU/RU) with higher-layer functions centralized (CU). The split reduces fronthaul bandwidth dem
