<p>can you try to reproduce with current master (there's been some fixes over last months in osmo-pcu and osmo-sgsn).</p>
<p>Otherwise, can you provide some pcap file or similar?</p> OsmoPCU - Bug #3472: GPRS connection is in a state where pdp-context is active, but data TX cannot initiate from Network side.https://osmocom.org/issues/3472?journal_id=172842020-01-22T11:40:12Zfixeria

<p>Hi <a class="user active" href="https://osmocom.org/users/4282">keith</a> , any news regarding this ticket?</p>
</blockquote>
<p>hi <a class="user active" href="https://osmocom.org/users/30187">pespin</a> I did try out some things last week as it happens, using a combination of nightly debian and locally built master for everything.</p>
<p>I tested both osmo-bts-uhd (Ettus N210 + locked gps module) and osmo-bts-sysmo (sysmoBTS 1002 calibrated) and I got inconclusive results.</p>
<p>Performance was still not satisfactory, but it's difficulte to control a manual test using phones with a range of data apps on them, to track down exactly what is happening.</p>
<p>Sometimes I observed that which looks like what this ticket describes. <br />Sometimes I still observed what looks like <a class="issue tracker-1 status-5 priority-2 priority-default closed" title="Bug: MS will not be able to use data service if we let the MS idle about 30 seconds after PDP context ... (Closed)" href="https://osmocom.org/issues/2455">#2455</a></p>
<p>I <em>still</em> observed the situation where I see a series of bursts on the uplink (just using gqrx + rtl-sdr) but the bts/pcu does not seem to "see" them, although I "think" this issue goes away when I patch osmo-pcu to use a fixed TA, sorry for useless vagueness.</p>
<p>My tests were cut short due to local complaints about the fan noise from the N210 - which is you know.. quite irritating! :-)</p>
<p>I'll try to find an hour today to see if I can get something more useful to you.</p> OsmoPCU - Bug #3472: GPRS connection is in a state where pdp-context is active, but data TX cannot initiate from Network side.https://osmocom.org/issues/3472?journal_id=173512020-01-27T16:36:20Zkeith
<ul></ul><p><a class="user active" href="https://osmocom.org/users/30187">pespin</a> , my whole weekend got taken up with server maintenance :-(</p>
<p>I will wait for your patches in <a class="issue tracker-1 status-3 priority-2 priority-default closed" title="Bug: pcu is logging "Allocating DL TBF: MS_CLASS=0/0" ; TLV parsing code commented? (Resolved)" href="https://osmocom.org/issues/3499">#3499</a> and then test things.</p>
<p>thanks!</p> OsmoPCU - Bug #3472: GPRS connection is in a state where pdp-context is active, but data TX cannot initiate from Network side.https://osmocom.org/issues/3472?journal_id=179132020-03-31T20:19:08Zkeith
<ul></ul><p>I can no longer reliably reproduce this issue. :-)</p>

<li>it's old, I don't remember all the conditions at the time and I posted insufficient info to understand fully what was happening.</li>
<li>There are other issues that better describe current problematic behaviour observed.</li>
