Abstract: The Radio Access Network (RAN) in a UMTS/ W-CDMA network might experience downtime of long durations which occur as a result of failure, malfunction, physical damage or maintenance shutdown of its components. During the down time ,which may last from several hours to days, calls and other services will not be supported in the User Equipments(UE) or mobile phones located among the various cells controlled by the RAN. In order to reduce this downtime to few minutes, before the network is restored, the Radio Network Controller(s) (RNC) need to be backed up-so that when a particular RNC malfunctions, the backup takes over all its functionalities and returns the control once the original RNC is up. The protection of a RAN against undesirably long downtime is essentially the protection of its RNCs because RNCs are unarguably the most important components of a UTRAN which controls several Nodes Bs or the Base Transceiver Stations (BTS) which in turn control the “cells”. Several RNCs could be configured with a backup RNC which is located far away physically and remains idle and could be activated only when the original RNC(s) are down. In this paper, the automation framework for activating the backup RNC has been described so as to achieve Protection Of the Network.
