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_--_a... but at least when this is verified/clarified we should incorporate it in https://osmocom.org/projects/cellular-infrastructure/wiki/Getting_Started_wi...
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
