2G Long Call Rx Qual Sub Vs Drops

PRE POSTDrop Due to UE/NormalHO, Rx Qual related DropPoor CoverageInterference



Reason: Drop Due to poor coverage area Reason: Drop call Due to Co-BCCH CELL between the site 4600 2nd sec , BCCH 979 & SITE ID 4279 2nd sector BCCH 979



Reason : Poor coverage area Result call drop Reason : CO –BCCH Interference , Analysis : site 4868 1st sector BCCH 975 & SITE ID 8382 1ST

Sector having same BCCH 975 ,Result call Drop



Reason : Call Drop Due to Missing neighbor Analysis : Call Drop because UE Latched with the overshooting cell

34192 of the site 4192 , cause missing neighbor result call drop

Reason : CO –BCCH Interference , Analysis : site 4407 3rd sector overshooting BCCH 983 & SITE ID

4200 1ST Sector having same BCCH 983 ,Result call Drop,



Reason : Call Drop Due to interference /No Dominancy Analysis : due to adjacent interference between the site 4259 sector 2nd & site

id 4349 sector 1st BCCH ( 977 & 978 )and Due to poor quality Result call Drop

Reason : Overshooting /CO –BCCH Interference , Analysis : site 4169 2nd sector overshooting BCCH 984 & SITE

ID 4183 2nd Sector having same BCCH 984 ,Result call Drop,


2G Lock G900 Long Call Rx Qual Sub Vs Drops



2G Lock G900 Long Call –Drops Analysis-Handover & Rx Quality Drop

Reason: Poor coverage area & Co-BCCH Reason: Drop due to Co-BCCH interference between the overshooting cell 44119 of the site 4119 to 54065 of the site 4065


2G Lock G900 Long Call –Drops Analysis- Interferences Cause Drop

Reason : Adjacent bcch

Reason: Drop Due to interference because CI 44201 BCCH 980 & site id 8399 3rd sector Having same BCCH 980, Suspected sector swap on the site 4210



Reason: Call Drop due to Handover issue , Need to check handover Parameter between the cell 64167 to 44167 of the site 4167



Reason : UE normal Call drop Reason: UE normal call Drop RF conditions are good

Reason : Call Drop due to Handover issue between the cell 54162 site 4162 & cell id 64230 of the site 4230 .



Reason: Drop Due to handover issue , Need to check Handover Parameters between the cell 64118 to 64310

Reason: Drop Due to handover issue , Need to check Handover Parameters between the cell 54162 & 44310



Reason: Drop Due to Interference Analysis : Site id 4310 1st sector BCCH 986 & Site id 4118 1st sector having

same BCCH 986 .

Reason : UE normal call Drop



Reason : UE normal call Drop Reason : Call drop because UE Get hanged

Reason : UE normal call Drop



Reason : Call Drop Due interference because overshooting from the cell 44153 and creating CO-BCCH With the 1st sector of the site 4132

Reason : Call Drop Due to overshooting from the cell 45367 of the site 5367 , Result call drop

Reason : poor coverage area , Analysis : Call drop Because of poor cell at the

call drop point
