Cellular Network Infrastructure

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
