The evolution of mobile networks marks a significant leap in communication technologies, driven by the demand for high data rates, ultra-low latency, and enhanced connectivity. A key enabler in 5G is the adoption of Micro Service Based Architecture. Microservice Based Architecture decomposes the complex functionality of 5G Core Network into smaller Network Functions (NFs) that are microservice-based. Microservices provide numerous advantages such as ease of distribution and isolated updates. One of the biggest advantages of microservices is scalability and fault tolerance. But when we look at the future mobile network one alarming concern is sustainability. The energy consumed by these mobile networks is enormous along with that add up the CO2 emissions. An Energy Optimization Controller (EOC) collects energy statistics for the Network per slice/QoS/NF/UE level. It calculates energy efficiency and optimizes by dynamically managing the network.
