<h2>Benefits of GSM-WCDMA Inter-System Handover</h2>

<ul>
<li><p>When the networks overlap, handovers
from GSM BSS to WCDMA RAN can be made in order to reduce traffic load in the
GSM network</p>
</li>
<li><p>Handovers from WCDMA RAN to GSM BSS
can be made in order to enable the operator to provide a seamless coverage
in areas where WCDMA RAN is not available. The handover extends the radio
network coverage.</p>
</li>
<li><p>Due to the inter-system handover, seamless
continuity of speech connections and certain data services between WCDMA RAN
and GSM networks are available for all dual mode subscribers. Dual mode mobiles
support both GSM and WCDMA RAN. In addition to this, dual mode mobiles may
also support GPRS.</p>
</li>
</ul>
