<h3>Network-Controlled
Cell Re-Selection (NCCR)</h3>

<p>NCCR offers network-controlled cell re-selection for (E)GPRS
capable mobiles. Cell changes are determined according to different criteria.
After NCCR has defined a new cell for the mobile, the <a href="NED?action=retrieve&amp;identifier=general_glossary&amp;edition=13&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=id014238#id014238" onclick="openSmallPopup(event,'NED?action=retrieve&amp;identifier=general_glossary&amp;edition=13&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=id014238#id014238');return false" shape="rect" target="_blank">PCU</a>
informs NACC about the cell change and asks it to send data concerning the
neighbour cell to the mobile station to make the cell change faster.</p>
