I am an engineering student and I have started to work on my thesis. </div><div><br></div><div>I would like to perform a GPRS core network completely using virtual machine (virtual box based) and use it to prove that an operator can manage M2M traffic just using standard hardware, virtual machine and open source components (osmocom project ). </div><div><br></div><div>At this moment i deployed 4 virtual machine, one for each osmo component (osmoNITB, openGGSN, osmoSGSN) on the fourth VM I want to run the fakeBTS because I don't have a bts.</div><div><br></div><div>I would like to simulate it as if there are some M2M devices generate request(attach, pdp context for example).</div><div><br></div><div>When I try the communication between NITB and fakeBTS there are some error Messages related to RSL. Then there isn't communication between NITB-fakeBTS and SGSN-GGSN.</div><div><br></div><div>Do you detect any configuration error? </div><div><br></div><div>Thank you.</div><div><br></div><div>Best regard</div><div><br></div><div>Calo</div><div><br><br><font class="Apple-style-span" size="4"><span class="Apple-style-span" style="font-size: 14px;"><br></span></font></div><br><br><br>-------- Original message --------<br>Subject: Re: GPRS core network simulation <br>From: Harald Welte <laforge@gnumonks.org> <br>To: calogero cannizzaro <can_ni@hotmail.it> <br>CC: "openbsc@lists.osmocom.org" <openbsc@lists.osmocom.org> <br><br><br><div style="word-break:break-all;">Hi Calogero,<br><br>* what is the goal / use case of your simulation?<br>* what exactly do you need to simulate?<br>* what is the input/output of the simulation?<br><br>In general, the vaious Osmo-* implementations are not designed for<br>simulation buy for actual network operation. So you will likely need to<br>implement quite a lot in order to use it in a simulation context. The<br>most important question is, that you need code that will behave as<br>actual handsets on a network, and code to manage all those virtual<br>handsets, tell them what they should be doing, etc.<br>-- <br>- Harald Welte <laforge@gnumonks.org> http://laforge.gnumonks.org/<br>============================================================================<br>"Privacy in residential applications is a desirable marketing option."<br> (ETSI EN 300 175-7 Ch.
