<h3>Low measured absolute CPICH RSCP</h3>

<p>The parameter <span class="parameter-sem">GSMcauseCPICHrscp</span>
indicates whether an inter-system handover to GSM caused by low measured absolute
CPICH RSCP of the serving cell (or cells participating in soft handover) is
enabled.</p>

<p>When the measured CPICH RSCP value of all active set cells
has become worse than the reporting threshold, the RNC starts the inter-system
(GSM) measurement.</p>
