<h3>IMSI Based GSM-WCDMA Handover</h3>

<p>When IMSI Based GSM-WCDMA Handover is enabled, an IMSI based GSM-WCDMA
handover is initiated to a neighbour WCDMA cell of Authorised Networks (ANE)
as soon as the coverage of at least one neighbour WCDMA cell of ANE is available.
That is, the following equation is met:</p>


<p>A<em>V_ECNO_NCELL(n) &gt; minimum CPICH Ec/Io level(n)</em></p>


<p>If neighbour WCDMA cells belong to the same Authorised Networks, the
cells have equal handover target priority compared to each other regardless
of whether they belong to only one or several PLMN areas. The
WCDMA cells are set into priority order according to results of signal quality
measurements, which are done and reported by the MS to the host GSM network.</p>
