MS Power Control Loop: Use P_CON_INTERVAL=2 by default
Have a more stable loop with less temporary oscillations at the expense
of increased reaction time.
4 SACCH blocks (P_CON_INTERVAL=2) is the minimum interval to get stable
measurements for the last requested MS Power level. With P_CON_INTERVAL=1,
are also made during a period with stable power being use to transmit,
but the MS Power level used (and announced in MR) is not the last one
requested by the BTS, but the one requested in the previous loop
iteration. This can make the MS and BTS bounce 2 values forth and back,
and create some temporary oscillation.
See osmo-bsc User manual section "Power Control" for more information.
