The Open IMS Core is an Open Source implementation of IMS Call Session Control Functions (CSCFs) and a lightweight Home Subscriber Server (HSS), which together form the core elements of all IMS/NGN architectures as specified today within 3GPP, 3GPP2, ETSI TISPAN and the PacketCable intiative. The
... [More] four components are all based upon Open Source software(e.g. the SIP Express Router (SER) or MySQL). For almost three years the Open IMS Core has formed the heart of the Open IMS Playground @ FOKUS [Less]
Experimental cross-platform 3GPP NGN/IMS framework for embedded systems
doubango is an experimental open source, cross-platform 3GPP NGN/IMS framework for embedded systems (it also works on Windows XP/Vista/7, Mac OS X and unix-like systems).
The framework has been carefully designed to
... [More] efficiently work on embedded systems with limited memory and low computing power.
The SIP stack (RFC 3261) implements 3GPP TS 24.229 Rel-9 and can be used to develop VoIP applications targeting embedded systems, desktop computers, laptops, tablet PCs or handheld PCs.
SIP messages can be compressed using SigComp, protected with IPSec or TLS over IPv6 or IPv4 protocols. Both TCP and UDP are supported.
The media layer contains a complete SOA (SDP Offer Answer) framework with MMTel and PoC ex [Less]
Network link bonding/trunking/aggregation and multichannel VPN daemon for Linux
Vtrunkd is a Linux VPN daemon used to combine several connection paths into one aggregated channel. Features latency, reordering and jitter management, behaviour analysis optimizations for encapsulated protocols
... [More], bufferbloat control, packet redundancy, and multiple cpu cores utilization. Up to 30 heterogenous links bonding supported. Used for live streaming, LTE/3G/Wi-Fi link bonding. 32/64-bit, x86, MIPS and ARM supported. Supports python plug-ins for new algorithms implementation. Open source version developed and commercial support provided by Vrayo Systems [Less]
srsUE is an open source software radio LTE UE developed by SRS. It is written in C++ and builds upon the srsLTE library. Running on an Intel Core i7-4790, srsUE achieves up to 60Mbps DL with a 20Mhz bandwidth SISO configuration. srsUE is released under the AGPLv3 license and uses software from the
... [More] OpenLTE project for some security functions and for RRC/NAS message parsing. [Less]
OpenLTE is an open source implementation of the 3GPP LTE specifications.
Currently, octave code is available for test and simulation of downlink transmit and receive functionality and uplink PRACH transmit and receive functionality. In addition, GNU Radio applications are available for downlink
... [More] transmit and receive to and from a file, downlink receive using rtl-sdr, HackRF, or USRP B2X0, LTE I/Q file recording using rtl-sdr, HackRF, or USRP B2X0, and a simple eNodeB using USRP B2X0.
The current focus is on extending the capabilities of the GNU Radio applications and adding capabilities to the simple eNodeB application. [Less]
