osmo-hlr - Osmocom HLR Implementation

This repository contains a C-language implementation of a GSM Home Location Register (HLR). It is part of the Osmocom Open Source Mobile Communications project.

Warning: While the HLR logical functionality is implemented, OsmoHLR does not use the ETSI/3GPP TCAP/MAP protocol stack. Instead, a much simpler custom protocol (GSUP) is used. This means, OsmoHLR is of no use outside the context of an Osmocom core network. You can use it with OsmoMSC, OsmoSGSN etc. - but not with third party components.


The official homepage of the project is https://osmocom.org/projects/osmo-hlr/wiki
