The paging of the called party is performed during the sDCCH phase of the calling party. So TCH is not yet allocated to the calling party.
It would be allocated as soon as the called party’s MSC is replying to the “CALL SETUP” message by a “CALL PROCEEDING” message.7th February 2009 at 18:20 #51939Azzazi_RFoptimization_engGuest
