<h3>Low measured absolute CPICH Ec/No</h3>

<p>The parameter <span class="parameter-sem">GSMcauseCPICHEcNo</span>
indicates whether an inter-system handover to GSM caused by low measured absolute
CPICH Ec/No of the serving cell (or cells participating in soft handover)
is enabled. </p>

<p>When the inter-system handover is enabled, the RNC sets
up the intra-frequency measurement reporting events 1E and 1F in order to
monitor the absolute CPICH Ec/No value.</p>


<p>If the measured CPICH Ec/No value of an active set cell
becomes worse than the absolute threshold/parameter <span class="parameter-sem">HHoEcNoThreshold</span>,
the UE sends the event 1F triggered intra-frequency measurement report to
the RNC after the <span class="parameter-sem">HHoEcNoTimeHysteresis</span> time period.
When the measured CPICH Ec/No value of all active set cells has become worse
than the reporting threshold, the RNC starts the inter-system (GSM) measurement.</p>

<p><span class="parameter-sem">HhoEcNoCancel</span> determines the
absolute threshold which is used by the UE to trigger the reporting event
1E (a primary CPICH becomes better than an absolute thresold). <span class="parameter-sem">HhoEcNoCancelTime</span>
determines the period of time between the detection of the event 1E and sending
of the measurement report.</p>
