<h2 id="inter-rat-irat-handover">Inter-RAT (IRAT) handover</h2> <p>A mobile terminal, while connected using a RAT, performs neighbour cell measurements and sends measurement report to the network. Based on this measurement report provided by the mobile terminal, the network can initiate <a href="/facts/Handover/STj6E5RU">handover</a> from one RAT to another, e.g. from <a href="/facts/WCDMA/lhy2RrMw">WCDMA</a> to <a href="/facts/GSM/Sw8QYaLE">GSM</a> or vice versa. Once the handover with the new RAT is completed, the channels used by the previous RAT are released.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Radio_access_network/SSlTWVAj">Radio access network</a> (RAN)</li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>I.
