### 5G Functionality
The AMF also manages ongoing sessions for the device or user, monitoring QoS and ensuring that appropriate resources are allocated for the session. As a critical component of the 5G core network architecture, the AMF plays a crucial role in enabling seamless connectivity and mobility for 5G devices and users. 5. The Unified Data Management (UDM): It is a key component of the 5G network architecture that is responsible for managing user-related information, such as authentication and authorisation data, user preferences, and service subscriptions. The UDM is a centralised function that stores and manages all the user-related information that is needed by the 5G network, including information about the user's device, SIM card, and subscription. The UDM provides a unified view of user data to other network functions, allowing them to access the data they need to deliver services and manage network resources. The key functions of the UDM include authenticating users and authorising access to network resources based on their credentials and service subscriptions. The UDM provides policy control functions to manage network access, traffic routing, and other network resources based on user profiles and service requirements. The UDM manages subscriber data, including SIM card information, service subscriptions, and billing information. The UDM is a critical component of the 5G network architecture, providing a centralised repository for user-related information that enables other network functions to deliver customised and optimised services to users. 6. The Policy Control Function (PCF): The Policy Control Function (PCF) is a key component of the 5G network architecture that is responsible for managing policy decisions and enforcement in the network. The PCF acts as a centralised policy controller, defining and enforcing policies for network access, traffic routing, and other network resources. The PCF uses information from the UDM function to make policy decisions based on user profiles and service requirements. The PCF is an essential component of the 5G network architecture, providing a centralised function for policy control that enables operators to manage network resources and deliver customised services to users. By defining and enforcing policies for network access, traffic routing, and resource allocation, the PCF ensures that network resources are used efficiently and effectively, enabling operators to deliver high-quality services to their customers. Thus, the SBA places a strong emphasis on the deployment of virtualised functions using the Multi-access Edge Computing (MEC) infrastructure as a fundamental architectural tenet. MEC is an essential element of 5G infrastructure, which seeks to enhance cloud computing by relocating applications from centralised data centres to the edge network in closer proximity to end-users. This strategy offers numerous benefits, including reduced latency, increased bandwidth, and real-time access to RAN data. The implementation of MEC is particularly important for the Command and Control (C2) link, which requires extremely low-latency communication. The proposed algorithm is implemented in a cloud-based architecture as part of the SBA infrastructure discussed above.
