    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 :
