Description

The way how OsmoBTS interprets the A-bis RSL information elements regarding MS and BS power control is wrong.

For a description of the current behavior, see http://openbsc.osmocom.org/trac/wiki/GsmPowerControl

Furthermore, even the actual power control loop is completely simplistic, results in oscillations and doesn't implement any of the configurable averaging as specified in TS 05.08.

What needs to be done is:
correctly parse and interpret the various MS / BS power related IEs on RSL
implement Annex A of TS 05.08 (measurement averaging, MS power control)
