Feature #3189
make retrieval of IMEI configurable
100%
Description
We also have unit tests that go through these scenarios and verify they work.
What we still need is to switch them on: add vty config to set vlr_instance.cfg values:
- check_imei_rqd
- retrieve_imeisv_early
- retrieve_imeisv_ciphered

#2541 depends on this, so I wrote a patch to implement it. I didn't know how to describe all of the parameters though.
https://gerrit.osmocom.org/#/c/osmo-msc/+/12302/
I've tried to test it, but was unsuccessful:- set "check-imei-rqd 1" in osmo-msc.cfg
- run the CN with a sysmoBTS connected
- run wireshark with filter set to: gsup
- connect a phone
- now I expected some check-imei-related messages to appear. But I only got the usual:
UpdateLocation Request
InsertSubscriberData Request
InsertSubscriberData Result
UpdateLocation Result
neels, laforge: what does this mean, was my testing done wrong?

#5 Updated by osmith about 2 years ago
Turns out, we don't send a GSUP message to the HLR/EIR yet (this explains my wireshark test results).
This issue should be complete with the submitted patch nevertheless, but we still need to fill in the missing descriptions.
#6 Updated by osmith about 2 years ago
I've changed the patch to only enable check-imei-rqd, because that is the only option that is useful so far. It will send the IMEI to the HLR/EIR, as it has just been implemented in #3733.
The other options are not that useful yet, they will ask the device for the IMEISV, but then do nothing with it.
See neels' third reply here: https://gerrit.osmocom.org/#/c/osmo-msc/+/12302/1/src/libmsc/msc_vty.c@448
The patch has been merged.
neels: can we set this issue to resolved?
#7 Updated by neels about 2 years ago
even though IMEISV is only stored in VLR, that part is not configurable yet, right?
We could split this issue: make this one ask for IMEI only and create a new one for IMEISV.
We could also just add vty config for IMEISV even if nothing is happening with it, and add IMEISV->HLR some other time.

Right.

Sounds good, done: #3755.
