As Long-Term Evolution (LTE) systems evolve to meet growing data traffic and service demands, Network Function Virtualization (NFV) has emerged as a key enabler to improve network flexibility, scalability, and cost-efficiency. However, the performance and reliability of NFV implementations in LTE environments remain a significant challenge due to latency issues, resource allocation inefficiencies, and the complexity of ensuring consistent service availability. This paper addresses these challenges by proposing a novel framework that enhances NFV's operational efficiency and reliability within LTE networks. The framework integrates dynamic resource management techniques with intelligent orchestration policies, which optimize the allocation of virtualized network functions (VNFs) while minimizing the impact on system performance. Additionally, the solution introduces enhanced failover mechanisms to mitigate the risks of service disturbence during VNF migration or hardware failures. Experimental results demonstrate improved throughput, reduced latency, and higher service availability compared to existing NFV solutions. This contribution significantly advances NFV's potential to support next-generation LTE systems, paving the way for more robust and adaptable mobile network infrastructures
