OpenBSC and 3G

Hello Everyone, I now have OpenBSC (including GPRS) up and running with a fair amount of stability, using an IP.Access 2G BTS. Now I am looking towards the next stage - getting a 3G system operating. I have the use of an IP.Access NodeB that I would like get running with OpenBSC. In performing my due diligence, I found Harald's 3G road map from December 2010 or so. I am wondering what the current state of development is. I see that IP.Access' URSL protocol was an issue back then, because it is proprietary. Has anyone managed to get far enough in their development that they have implemented the protocol? I also see from Dieter Spaar's blog that he is making some progress, but he states his code is not ready for public release. Since I don't see much about 3G on the OpenBSC wiki, I am assuming that no one has any code that they would want to share at this point. I imagine I may have to forge ahead on my own. I am fairly new to GSM development, and I haven't really delved into the OpenBSC source yet (other than to discern what might have caused some problems I encountered), so if anyone has any suggestions on where to begin, or has some issues where I might be able to assist in order to move development further down the road, please let me know. Thanks! John
