Impact of Call Reestablishment on Network:
By using call reestablishment feature in the WCDMA we can reuce the call rop in C! an "!
omain# $his feature enables us to successful reestablish the call after the abnormal release
inication has been sent by the RNC#

$he re%establishment proceure allows M! to resume a connection in progress after a
raio link failure& possibly in a new cell or in a new location area 're%establishment in a
new location area initiates no location upating(#
$he C! call rop analysis is as shown below the basic counter responsible for the call rops
are as mentione :

$he call re%establishment etails are transmitte in the !IB / an !IB 0+ after the release
inication has been recei1e a counter N202 starts which repeats it self for the times $202

We nee to increases these timers in orer to pro1ie .3 the time for re%latching an
making a call re attempt for the RAB new connection#
