Overview
This is a group of Osmocom programs implementing cellular network infrastructure components for GSM, GPRS, EDGE, UMTS, HSPA, LTE and their associated interfaces and protocol stacks.
This includes components for classic circuit-switched GSM:
- OsmoBTS implementing a GSM Base Transceiver Station
- optionally together with OsmoTRX to implement the GSM physical layer on a Software Defined Radio
- OsmoBSC implementing an IP-based GSM Base Station Controller with Abis/IP and 3GPP AoIP interface
- OsmoMSC implementing an IP based GSM and UMTS Mobile Switching Center with 3GPP AoIP and Iu-CS interface
- OsmoHLR implementing a minimalistic HLR compatible only with OsmoMSC
- OsmoSTP implementing a minimalistic Signal Transfer Point for M3UA, SUA and SCCPlite
- OsmoNITB, our legacy implementation a minimal network-in-the-box with Abis/IP interface
As well as the following components for GPRS/EDGE networks:
- The OsmoPCU project, implementing a GPRS Packet Control Unit with Gb/IP interface
- The OsmoSGSN project, impleenting a Serving GPRS Support Node with Gb/IP, Iu-PS and GTP
- The OpenGGSN project, implementing a Gateway GPRS Support Node
Further projects related to UMTS/HSPA networks:
- The OsmoHNBGW project, implementing a HomeNodeB-Gateway with Iuh, Iu-CS and Iu-PS
