HLR - Home Location Register

The Home Location Register (HLR) is a central database in a mobile network that contains details of each mobile phone subscriber. It stores essential information such as:

  • Subscriber profiles

  • Current location

  • Service subscriptions

The HLR ensures that calls, SMS, and other services are delivered to the correct subscriber, regardless of their current location within the network.
