I won't have time for some days, but this looks like someone should
verify this. I'm still wondering why a "Routing Area Update Request" is
rejected, so some clarification could also be good...
And we should incorporate this information on our wiki; I see that it is
mentioned on
https://osmocom.org/projects/cellular-infrastructure/wiki/Accelerate3g5_--_…
but at least when this is verified/clarified we should incorporate it in
https://osmocom.org/projects/cellular-infrastructure/wiki/Getting_Started_w…
Many thanks so far, Andreas!
I also noticed from your Accelerate3g5 page that the getting started guide
lacks the creation of the hlr.db. I added this to the main guide now (but
used the new default db name of 'hlr.db').

Hello,
today the UMTS-USB-stick established a successfull IP-connection on the first attempt,
but further attempts failed. When comparing packet-dumps of a successful and a failed
connection-attempt and looking and the RANAP and GTP-packages I saw, that on the failed
connection-attempts the UMTS-Stick is not authorized and on the successful attempt at
first a location-update is made and then the authentification, which succeeds.
Adding the command "AT+CREG" to wvdial.conf seems to solve the problem. Then I
can see an "Routing Area Update Request" which is rejected then the
authorization happens (Attach, Identity, Authentication) and the IP-connection is
successfully established!
Here is a working wvdial.conf for the huawei E1823:
[Dialer Defaults]
Init1 = AT^U2DIAG=0
Init2 = AT+CREG
Init3 = ATZ
Init4 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","web.blubb.xy"
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
Stupid mode = 1
ISDN = 0
Phone = *99#
Password = none
Username = none
It takes very long (>30 seconds) until ppp0 receives the IP-config but afterwards it
is working with 6625 kBit/s down- and 580kBit/s upstream.
greetings,
Andreas
