Case 1: Drop due to missing neighbor Problem: Detected Nighbor (DN)Mobiloe Station sends a Report ,which it measured in site ,that contains event 1A means adding anew RL (cell) to Active SetThereported cell should be present in current neighbor cell list,I it not available means! andthenreported"c#$o is better thanthe best serving cell "c#$o in AS b% some d&s (set b% a R$'parameter)In any movement,new cell can not be added to Aativr Set,i we addd means ,call will be released

Figure : Drop -due -to -missing- neighbor

Case 2: Drop due to Poor Coverage (low RCP)

Problem: Poor D! coveragehen Mobie Station have a low RS' value ( * +1- d&m).At the time! "c#$o values,call /ropwill happen,Mobilw Staion! will li0el%lift up up the transmitted power and reach its ma power.The /L &L"R will probabl% increase and SIRtarget cannot maintain an%more, inall% the call drops.
