The YateUDM stores and manages the SIM database for mobile networks. It also manages multiple subscriber identities (from different technologies) in one server, providing seamless services over different networks. It is designed for use in GSM, UMTS, LTE, IMS, WiFi and 5G SA / NSA networks or any other type of network that uses MAP, Diameter or CAPIF for authentication.

The YateUDM for 5G includes Authentication Server Function (AUSF), Unified Data Repository (UDM) and Network Slice Selection Function (NSSF).

For LTE, GSM and 3G Includes a Home Location Register (HLR), an Authentication Center (Auc) (2G/3G) and a Home Subscriber Server (HSS) (4G LTE). The YateUDM exports a JSON API for integration with any SIM management and CRM systems. It is capable of interconnecting with all the VLRs implemented in a GSM mobile network, with any MME from a conventional LTE network, or with the YateUCN5G core network server.

As it is also an AuC and AuSF, the YateUSM authenticates subscribers as they try to connect to the GSM, UMTS, LTE, or the 5G networks to make phone calls, send SMSs and access mobile data.

YateUDM is easy to operate and manage remotely using the Yate Mobile Management Interface (MMI) online.
