The Home Location Register (HLR) and the Authentication Center (AuC) holds information about a GSM Subscriber. This includes static information about the subscriber including IMSI, the phone number, the private key and dynamic information about the current location of the subscriber for packet and circuit switched operation.
The HLR has been developed using our TCAP implementation and supports both 3GPP Camel and none 3GPP Camel operations. For 3GPP Camel an external Service Control Function (SCF) is required. The HLR includes the full source code and unit tests allowing it to be modified for specific use-cases of small- and medium-sized providers. This is following our custom-tailored GSM approach.
