closedIssue with registering phones to Network
0%
Description
Hi,
I try to build a 2G GSM Network using OsmoTRX, OsmoBSC, OsmoHLR and other software that are required. But I have a problem I cannot solve. I do this because I wanted to learn how a GSM structure works but I never had experience before. I am using the Ettus USRP B210. So to come to my issue.
In OsmoHLR I can register my subscribers and the 2G activation is done correctly. Bu when I try to register my phones in the Network by selecting the Network I get a message "Network Connection Failed"
So first i will give the commands which software I started
sudo osmo-trx-uhd -C ~/osmocom/osmo-cfg/osmo-trx-usrp_b200.cfg
sudo osmo-hlr -l hlr.db -c ~/osmocom/osmo-cfg/osmo-hlr.cfg
sudo osmo-msc -c ~/osmocom/osmo-cfg/osmo-msc.cfg
sudo osmo-mgw -c ~/osmocom/osmo-cfg/osmo-mgw-for-msc.cfg
sudo osmo-mgw -c ~/osmocom/osmo-cfg/osmo-mgw-for-bsc.cfg
sudo osmo-ggsn -c ~/osmocom/osmo-cfg/osmo-ggsn.cfg
sudo osmo-sgsn -c ~/osmocom/osmo-cfg/osmo-sgsn.cfg
sudo osmo-stp -c ~/osmocom/osmo-cfg/osmo-stp.cfg
sudo osmo-bsc -c ~/osmocom/osmo-cfg/osmo-bsc.cfg
Now I will give the config files

So will also add a screenshot of all programms working together
My problem is when i try to register my phone to the networ it is saying "Network connection failed"
The SIM I am using for are SIMCards from my-sim.com. But I cannot rewrite the ki. I tried to register them in osmo-hlr without the ki code.
The transceiver I am using is the Ettus B210 with osmo-trx
Does anyone have a solution. I was thinking maybe I did some mistakes in the configuration.
If someone has a instruction it would be nice
Kind regards

this issue was undiscovered as it was in the "testproject" and not related to any actaul osmocom software. I guess nobody watches additions to the "testproject", which is just used to test the redmine issue tracker :/
@rukancp: Is this still an issue?

Please don't attach screenshots, they are useless in 90%. Instead, you could attach your configuration files and logs.
