<div class="moz-cite-prefix">Reminds me of the old DataTac network.
Same thing occurred there, if and RNG failed, if the switch-over
to the standby failed for some reason, the resulting registration
storm caused the network to fall-over for 18 hours. I ended up
writing an app to command userland devices to stagger/hold off
registration based on (last digit of serial number x time in
seconds).<br>
<br>
Solved the issue nicely.<br>

So from what I've been reading apparently an engineer restarted an
MME without migrating the customers manually to another MME, which
I assume then booted a heap of them off the network? Apparently
the registration storm from that then overloaded the remaining
MME's which then caused all of the things to break?<br>
<br>
I hear they're blaming the engineer because he didn't migrate
customers over to another MME, but what if they had an actual
failure in the MME? It sounds like the network isn't designed to
handle the resulting authentication (over)load and completely
falls over-- so as much as the engineer triggered the fault, I'm
not sure it's entirely his fault that it then went to complete
shit?<br>
<br>
(I'll admit I'm very green on the UTRAN/E-UTRA stuff, but it's
something I have immense curiosity about, if someone can correct
me, or point me in the right direction if I'm wrong here, I'd be
much appreciative)<br>

<p class="MsoNormal">Well, it is possible for a 4G HSS
(HLR in the 3G world) to go down. That report however
makes me think it might have been an MME... Given it was

couldn't be set up in a redundant configuration, so if
you didn't have enough, or one failed, you couldn't
redirect traffic from all the connected base stations.
Now you can with MMEs, and that would be consistent with
this description.<o:p></o:p></p>
