| About OpenBSC |
| ============= |
| |
| OpenBSC started as a minimalistic all-in-one implementation of the GSM Network, |
| with particular emphasis on the functionality typically provided by the BSC, |
| MSC, HLR, VLR and SMSC. Today it is a growing suite of libraries and programs, |
| implementing protocol stacks and functional elements, including |
| |
| * OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC |
| * OsmoBSC-MGCP - MGCP helper to the OsmoBSC software |
| * OsmoNITB - a BSC+MSC+VLR+HLR+SMSC "Network in the box". |
| * OsmoMSC - a voice CN with A/IP and IuCS/IP towards the BSC and/or HNB-GW |
| * OsmoSGSN - a GPRS SGSN with Gb/IP and IuPS/IP towards the PCU and/or HNB-GW |
| * Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN |
| * OsmoBSCNAT - a gateway aggregating many A links as one A link to the MSC |
| * OsmoGTPHUB - a hub aggregating many GTP links (between SGSN and GGSN) |
| * ipaccess-utils - some tools to discover + configure ip.access nanoBTS |
| * bs11_config - a tool to configure the Siemens BS-11 microBTS |
| |
| Various interfaces towards the BTS are supported, among which are: |
| |
| * Classic A-bis over E1 using a mISDN based E1 interface. In other |
| words, you can connect existing GSM Base Transceiver Station (BTS) |
| through E1 to OpenBSC. So far, we have made it work with the Siemens BS-11, |
| various Ericsson RBS2xxx BTS models and the Nokia MetroSite. |
| |
| * A-bis over IP as used by the ip.access nanoBTS product family as well as |
| the Open Source OsmoBTS software (by the same authors as OpenBSC). OsmoBTS |
| in turn supports various transceiver hardware, including the sysmoBTS |
| product family, as well as SDR transceivers supported by OsmoTRX, such as |
| the UmTRX or USRP boardss. |
| |
| * IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G) |
| voice and data links. |
