Cellular Network Infrastructure » OsmoGSMTester

I started looking into this and do some manual tests.

Right now I have nano3g in RnD setup controlled by smart sispmctl 3, and shows up with "abisip-find -i 1 -j -b 10.42.42.1".

{ "MAC_Address": "00:02:95:07:d1:2e", "IP_Address": "10.42.42.121", "Unit_ID": "1/1/1", "Location_1": "Unknown", "Location_2": "3GAP", "Equipment_Version": "237B015_C", "Software_Version": "unknown", "Unit_Name": "Unknown", "Serial_Number": "000295-0000123021" }

I can telnet and ssh into it, following https://projects.osmocom.org/projects/cellular-infrastructure/wiki/Configuring_the_ipaccess_nano3G#SSH-Access

Some stuff which will be needed in osmo-gsm-tester to control it:

• Add nano3g MAC address to the DHCP server in osmo-gsm-tester main unit. DONE https://gerrit.osmocom.org/c/osmo-ci/+/15586 ansible: gsm-tester-rnd: Add nano3g device to static IP DHCP leases
• Add an osmo-hnbgw class
• create a 'femtocell3g' resource type with subtypes (like 'bts' resource type)
• Move abisipfind from bts_nanobts.py to its own file (we can re-use it to wait until nano3g is up after using the smart socket)
• create a femtocell3g_nano3g.py class with the implementation:
  • power on with smart socket
  • wait until abisipind finds it
  • telnet nano3g_ipaddr 8090, or use: ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 -c aes128-cbc root@10.42.42.121 /opt/ipaccess/DMI/ipa-dmi -c '$CMD'
    • set mcc="901"
    • set mnc="70"
    • set rfParamsCandidateList=({9800, 401, 1})
    • set lacRacCandidateList=({10422, (99)})
    • set hnbCId=1
    • set rncIdentity=0
  • reboot properly with ssh (required to get changed params applied): ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 -c aes128-cbc root@$nano3g_ipaddr reboot
  • sleep a few seconds (to avoid getting abisipind results previous to reboot) and wait until abisipfind finds it
  • telnet nano3g_ipaddr 8090
    • set hnbGwAddress="$osmo_hnbgw_ipaddr"
    • action 2061
    • action 1216
    • action establishPermanentHnbGwConnection
    • set csgAccessMode=CSG_ACCESS_MODE_OPEN_ACCESS
