Neels Hofmeyr nhofmeyr at sysmocom.deI 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_--_andreas but at least when this is verified/clarified we should incorporate it in https://osmocom.org/projects/cellular-infrastructure/wiki/Getting_Started_with_3G 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'). ~N On Fri, Apr 07, 2017 at 07:52:15PM +0200, Andreas Mueller wrote: > 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 > -- - Neels Hofmeyr <nhofmeyr at sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte -------------- next part -------------- A non-text attachment was scrubbed...
