HSS/HLR/AuC SIM subscribers management


The YateHSS/HLR 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 networks or any other type of network that uses MAP or Diameter for authentication.

The YateHSS/HLR includes a Home Location Register (HLR), an Authentication Center (Auc) (2G/3G) and a Home Subscriber Server (HSS) (4G LTE). The YateHSS/HLR 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 YateUCNTM core network server.

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

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

The interface makes it accessible to add a new YateHSS/HLR unit, to setup a cluster of YateHSS/HLRs, to add subscribers, to modify and configure subscribers´ profiles and more. YateMMI’s main benefit is the fact that operators can remotely manage their entire network equipment using a single web interface.

Features and benefits

  • The YateHSS/HLR is fully implemented in software and uses commodity hardware.
  • Can serve as a proxy between an existing 2G/3G HLR and an LTE network.
  • Uses the SS7 MAP interfaces when serving as an HLR with other 2G/3G network equipment.
  • Provides Diameter support.
  • Supports groups for mobile data and CAMEL profiles.
  • Scalable by adding more HSS/HLR components, either distributed or load balanced.
  • Exports a JSON API for custom features.
  • Managed via a web-based management interface – YateMMI.
