Welcome to Open IMS Core’s Homepage
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 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
The home of the project on SourceForge is at https://sourceforge.net/projects/openimscore/
Mandatory disclaimer, before any usage
It has to be noted that this Open Source IMS Core System is not intended to become or act as a product in a commercial context! Its sole purpose is to provide an IMS core reference implementation for IMS technology testing and IMS application prototyping for research purposes, typically performed in IMS test-beds.
Users of the Open Source IMS Core System have to be aware that IMS technology may be subject of patents and license terms, as being specified within the various IMS-related IETF, ITU-T, ETSI, and 3GPP standards. Thus all Open IMS Core users have to take notice of this fact and have to agree to check out carefully before installing, using and extending the Open Source IMS Core System, if related patents and licenses may become applicable to the intended usage context.
