Unified Data Management (UDM) serves as the central control plane function of the 5G core network, bearing similarities to the Home Subscriber Service (HSS) in 4G networks. As a key component of the 5G system, UDM provides a centralized platform for network user data processing across multiple generations of mobile networks, including 2G, 3G, 4G, and 5G.
UDM plays several critical roles within the 5G network ecosystem:
· Unified Data Management: UDM acts as a central hub for user data, unifying information from various mobile network generations and facilitating seamless transitions among them.
· User Identity and Access Management: The UDM stores and manages essential subscriber information, including credentials, subscriptions, and service profiles. In essence, it functions as a comprehensive user directory for the network.
· Mobility Management: UDM ensures uninterrupted connectivity by tracking user location and updating the network when users move between different cell towers.
· Policy Enforcement: The UDM enforces network policies defined by the operator, such as data usage limits and Quality of Service (QoS) priorities for various users.
· Network Function Communication: UDM facilitates communication between various network functions within the 5G core, ensuring they have the necessary user data to operate efficiently.
