Description

Following-up from #3284:

Maybe a good start would be some brainstorming on the kind of logging or log processing we'd have to do in order to properly analyze this.

Maybe we even should send the occasional PACKET MEASUREMENT ORDER to the MSs so we get their view on actual measurement values even in packet transfer mode?

That should allow us to plot per-MS graphs on their view of neighbor cells over a time line.

daniel: Could we create test scenarios for the NG40 RAN simulator which would simulate inter-PCU cell re-selection towards the SGSN? The idea would be to simulate a number of PS-attached MS, which then move around the network, causing the MS to move from one simulated PCU to other simulated PCUs.

The Implementation under Test (IUT) would be OsmoSGSN in this case, with OsmoHLR + OsmoGGSN in place to make it operational.
