Today it is a growing suite of libraries and programs, -implementing protocol stacks and functional elements, including +OsmoMGW originated from the OpenBSC project, which started as a minimalistic +all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached +maturity and diversity (including M3UA SIGTRAN and 3G support in the form of +IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one +approach to fully independent separate programs as in typical GSM networks. - * 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 +OsmoMGW was one of the parts split off from the old openbsc.git. It originated +as a solution to merely navigate RTP streams through a NAT, but has since +matured to a Media Gateway implementation that is capable of streaming RTP for +2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time +of writing) transcoding between TRAU, various RTP payloads and IuUP. -Various interfaces towards the BTS are supported, among which are: +The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and +OsmoBSC, and receives and sends RTP streams as configured via MGCP. - * 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. +The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found +in osmo-msc.git) to instruct OsmoMGW via its MGCP service. - * 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. +The libosmo-mgcp library exposes MGCP server utilities used by e.g. OsmoBSC-NAT +(found in osmo-bsc.git) to navigate RTP streams through a NAT. +(At time of writing, this is still called libosmo-legacy-mgcp.) - * IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G) - voice and data links. - -Find OpenBSC online at -http://openbsc.osmocom.org/ - - Harald Welte <laforge at gnumonks.org> +Find OsmoMGW issue tracker and wiki online at +https://osmocom.org/projects/osmo-mgw +https://osmocom.org/projects/osmo-mgw/wiki -- To view, visit https://gerrit.osmocom.org/3782 To unsubscribe, visit https://gerrit.osmocom.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I84cba73b4366c6b403f7da587f46cf621e58c33f Gerrit-PatchSet: 1 Gerrit-Project: osmo-mgw Gerrit-Branch: master Gerrit-Owner: Neels Hofmeyr <nhofmeyr at sysmocom.de> Gerrit-Reviewer: Harald Welte <laforge at gnumonks.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: Neels Hofmeyr <nhofmeyr at sysmocom.de>
