<h3>Interaction with inter-frequency handover </h3>

<p>If the serving cell (or cells participating in soft handover)
has neighbour cells both in another carrier frequency and in another radio
access technology (GSM), and the RNC receives the Service Handover IE from
the core network (CN), the RNC determines the priorities between inter-frequency
and inter-system handovers on the basis of Service Handover IE value: </p>


<ul>
<li><p><em>Should be handed
over to GSM</em>: Handover to GSM has priority over the inter-frequency
handover. In this case the RNC does not start inter-frequency measurements
until the inter-system (GSM) measurements are completed, that is, when no
neighbour GSM cell is good enough for the quality and/or coverage reason handover.</p>
</li>
<li><p><em>Should not be handed
over to GSM</em>: Inter-frequency handover has priority over the handover
to GSM. In this case the RNC does not start the GSM measurements until the
inter-frequency measurements are completed, that is, when no neighbour cell
is good enough for the quality and/or coverage reason inter-frequency handover.</p>
</li>
<li><p><em>Shall not be handed
over to GSM</em>: Inter-frequency handover has priority over the handover
to GSM. In this case the RNC does not initiate GSM measurements or handover
to GSM even if no neighbour cell is good enough for the quality and/or coverage
reason inter-frequency handover.</p>
</li>
</ul>


<p>If the RNC does not receive the Service Handover information
element from the CN, the inter-frequency handover has priority over the handover
to GSM as a default value.</p>
