Based on the Universal Subscriber Profile Platform (ZXUN USPP), ZTE SDM (subscriber data management) solution complies with the 3GPP UDC concept, adopts the fully distributed architecture, and stores and processes the user data and service data distributed in each network in a centralized manner, to build a unified and integrated data center for the carrier.
It supports network function convergence such as GSM HLR, UMTS HLR, EIR, MNP, HLRe, FLR, IMS HSS, EPC HSS, 5G UDM, 5G AUSF, SLF, AAA, ENUM and DSC, and implements unified management of 2G/3G/4G/5G/IMS subscriber data. It supports unified mobility management, unified policy management and unified signaling routing under multi-access and multi-network, helping the carrier simplify the network and improve the operational efficiency.
It supports data exposure and provides multiple APIs to flexibly meet the requirements of diversified new service development.
It supports cloudification unified data layer, services-data separation, stateless design, and acceleration of new service deployment.
ZTE's SDM (subscriber data management) solution has been used in more than 100 countries and regions, with the largest convergent vHLR/HSS commercial project.
