automatic simulator for large LU load
Every so often we see systems suffering a lot from large LU load.
There are many tunables like each tx delay/integer, access control class ramping, ms-acces-lv-min ramping, doewnlink poweer ramping, im ass reejct timer, etc
In order to be able to test different configurations and possible patches, we need a reproducible test scenario for benchmarking our performance.Ideally this shoiuld be possible with osmocombb and virtphy. For just performing a LU, we don't even need scripting. However, we need
- starting large number of "mobile"
- realistic timing for network scan / cell search (virtphy is too fast)
- implementation of downlink attenuation
- detection of RACH collisions in bts-virtual
