<h1>Optimisation of the MS Power Level in Handovers</h1>

<p>The optimisation of the MS power level in handovers is
a feature, which is designed to cut down the probability of high RF power
peaks in the uplink after both intra-cell and inter-cell handovers and also
in call set-ups and so reduce the uplink interference in the radio network.</p>


<p>The BSC determines which RF power level the mobile station
that has been handed over will use as the initial RF power in the target cell
in inter-cell handover. The RF power will be determined for the serving cell
in case of intra-cell handover and in call set-up to be used as the initial
RF power. The default initial RF power level is the maximum RF power that
an MS is permitted to use on a traffic channel in the target cell but, in
case of an intra-BSC handover and call set-ups, the BSC is also able to optimise
the initial RF power level so that the RF power level is lower when the radio
link properties of the target cell / serving cell are good. The optimisation
is based on the downlink signal level of the adjacent cell and operator defined
parameters (as per adjacent cell).</p>
