Osmocom HLR

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 GSUP protocol.

Binary Packages

Osmocom provides binary packages for several flavors of Debian and Ubuntu GNU/Linux on a variety of architectures (i586, x86_64, armhf, armv7l). Unless you are a software developer interested in developing on Osmocom, it is recommended you use those packages instead of building from source.

For more details see Binary_Packages
