Cell Reselection

. Principle

.. Concepts

In ell reseletion /ode! the in the idle state reselets a ell. Cell reseletion islassified into intra-fre;ueny ell reseletion! inter-fre;ueny ell reseletion! and inter-radio aess tehnology (*T) ell reseletion. This dou/ent desries inter-*T ellreseletion.

The inter-*T ell reseletion is i/ple/ented in two steps3 neighoring-ell /easure/entand ell reseletion. The neighoring-ell /easure/ent is different in proess! dependingon the ell priority. The following setions desrie ell priority! neighoring ell standards!and ell reseletion standards.

..! Cell Priority

Cell reseletion is perfor/ed ased on ell priority. * user e;uip/ent () an otain the

ell priority fro/ syste/ /essages or dediated signaling (C Connetion elease). If the reei7es syste/ /essages and also reei7es the dediated signaling indiating the priority of the sa/e ell! the ell priority in the dediated signaling pre7ails.
