OsmoHLR, the Osmocom HLR is a minimal implementation of the Home Location Register, the subscriber database of a 2G/3G cellular network.  It stores parameters such as the IMSI and MSISDN of each subscriber, together with the secret key material (Ki, K/OP/OPc) in order to generate authentication vectors.

OsmoHLR *does not support the classic TCAP/MAP protocol* but rather implements the more light-weight [[cellular-infrastructure:GSUP]] protocol.
