Huawei SDM solution is positioned as a true cloudification converged data center of the entire network. It also provides basic subscriber management functions, such as mobility management, access authentication, and service authorization. It builds a unified and convergent data center to manage subscriber data efficiently and flexibly. It supports hybrid deployment of NEs including the UDM, AUSF, IMS-HSS, SAE-HSS, AAA, ENS, HLR and EIR. Such deployment enables 2G, 3G, 4G, 5G, VoLTE, and VoWiFi subscriber data to be managed in a centralized manner, ensures consistent experience for subscribers when they access different types of networks, and helps carriers simplify their networks, implement unified service provisioning, and improve operation efficiency.
Manages subscriber data in a unified manner, integrates multiple NEs, and provides high reliability and low latency, ensuring consistent experience for subscribers when they access different types of networks.
Provides a highly integrated data platform, simplifying network deployment, allowing flexible and scalable capacity expansion, and improving network security and operation efficiency.
Provides a convergent data model to integrate third-party services flexibly, accelerating the rollout of new services.
The UDM's functions, such as gray upgrade of subscriber data, global-local architecture, subscriber priority-based intelligent flow control, and FE/BE full mesh redundancy, ensure the reliability of subscriber data on the entire network in terms of maintenance, architecture, and NEs.
It provides carriers with convergent data management for 2G/3G/4G/5G networking scenarios. The UDM features efficient subscriber data processing, and simplified networking based on which existing services are compatible and 5G services can be expanded. Unified O&M reduces O&M costs.
It supports hybrid networking during NFV evolution, allows ATCA-based sites to smoothly evolve to CloudDB sites. It can automatically migrate subscriber data from the HSS to the UDM, reducing the impact on devices on live networks and protecting customers' existing investments.
4G subscribers can be provided with 5G services without changing their IMSIs or MSISDNs. It supports over 1000 enriched services for subscribers， like Consistent SS Experience, VoWiFi, Wi-Fi Offload and so on.
