OsmoDevCon 2022 ?

by Harald Welte

Dear fellow Osmocom developers, as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021, trying to compensate it at least to some extent with our OsmoDevCall every two weeks. The COVID-19 pandemic is far from over, and we don't know what the upcoming winter season will bring. Nevertheless, I think it would be a good idea to start a discussion of whether we should plan for an OsmoDevCon in 2022. I personally would say let's plan for the usual late April 2022 time frame, and if the pandemic situation deteriorates, we can still cancel it with something like one month lead time. I would also personally suggest to limit attendance to people who are fully vaccinated, and in addition do a self-test for all participants every morning. In terms of venue, we might also consider to move to a venue that allows better ventilation. Irrespective of the above we can also bring the air filters from the sysmocom office. So with that as an input statement, I would like to hear your opinion on the above proposals. Who would want to attend? Any complaints against the "vaccinated only plus daily self-tests in the morning" approach?

Questions about the SIM card for VoWiFi

by Hyunwoo Lee

Dear, I am Hyunwoo Lee. I am a newbie to configure the custom SIM card. I have one question in configuring sysmoISIM-SJA2 to enable VoWiFi on COTS UEs. The UEs that I am working on are Samsung Galaxy A21, OnePlus 7T, and Motorola G Power. I tried to make the UEs discover the ePDG by sending the DNS query and establish the IPsec channel with my IPsec server. I ran my own DNS server to reply with the IP address of my IPsec server on the DNS query. I tried to make it similar to the T-mobile setting since all of the UEs work well with the T-mobile SIM card. Unfortunately, I could not succeed in enabling VoWiFi on the UEs and I do not know why they do not work and what I can do further. I would appreciate it if someone could help me with this. I described what I did in detail below the line. Thank you in advance for your help! Sincerely, Hyunwoo Lee. ------------------------------ What I did is as follows: 1) Equipments - Two sysmoISIM-SJA2 - PC/SC CCID ISO7816 USB Smart Card Reader - UEs: Samsung Galaxy A21, OnePlus 7T, and Motorola G Power (all of them work well with the T-mobile SIM card) 2) Environment - Ubuntu 18.04 LTS - python 3.6.9 - pySim 1.0 3) Configuration of the SIM cards with pysim - The command that I used to configure the SIM cards (to T-mobile) was: : python3 pySim-prog.py -p 0 -a <adm value> -n name -x 310 -y 260 --imsi=3102601234567890 --msisdn=<telephone number> --epdgid= epdg.epc.mnc260.mcc310.pub.3gppnetwork.org --epdgSelection=310260 --ims-hdomain=ims.mnc260.mcc310.3gppnetwork.org --impi= sip:3102601234567890@ims.mnc260.mcc310.3gppnetwork.org --impu= sip:3102601234567890@ims.mnc260.mcc310.3gppnetwork.org --iccid=<ICCID value> - The mnclen value is set to 3 4) UE behavior with the SIM card - Samsung Galaxy A21 : It sends the DNS query for the ePDG, but does not execute the IKE protocol to establish the IPsec channel with the T-mobile core network. - OnePlus 7T and Motorola G Power : It does not send the DNS query for the ePDG. 5) Configuration result - The command that I used to read the SIM card : python3 pySim-read.py -p 0 - The result of the command Using PC/SC reader interface Reading ...
