Home Subscriber Server (HSS) / Home Location Register (HLR)

HSS/HLR - HSS network, HLR solution. What is HSS in telecom?

Every mobile network, including virtual operators, uses a server that stores subscriber information, current location and SIM details like IMSI (mobile subscriber identity) and authentication keys.
This server is called HLR for 2G and 3G networks using the SS7 protocol and HSS for 4G networks using the Diameter protocol for signaling.

To make this simpler we put all together in a single product called YateHSS/HLR that works for 2G, 3G and 4G networks using either protocol.

  • Benefits

  • Operators can start with small installations and scale up as needed

  • Compatible with SS7 and Diameter networks

  • Clustered solution

  • Scalable
    Each YateHSS/HLR server has a capacity of up to 100,000 subscribers. Because it uses software and commodity hardware, any number of new servers can be added to the network and automatically synchronized with the other servers.
  • Multi-technology
    The YateHSS/HLR is a unified solution for GSM, UMTS, LTE, IMS, and WiFi networks. It includes a Home Location Register (HLR) and Authentication Center (AuC) for 2G, 3G and 4G networks, and a Home Subscriber Server (HSS) for data and voice (IMS) in LTE.
  • Secure and reliable
    The HSS/HLR performs authentication over both Diameter and SS7 MAP for GSM, UMTS, LTE and WiFi. Unlike other solutions in its range, it supports configuration in a cluster of HSS/HLR nodes, which makes it redundant against failure.
  • Easy management
    The HSS/HLR uses a Linux-based operating system, allowing the operator to handle its management and operation. A JSON API and a web-based interface make the HSS/HLR easy to configure and manage.
