HSPA Dropped Events


2/25

Dropped Event 1Call drop observed on KAT711B(SC-070),need neighbor addition required as observed KAT726(SC-

67) & KAT1036 (SC-133) in detected set . For better optimization we can add these neighbours.


3/25

Dropped Event 2Call drop observed on KAT110C(SC-140) with low coverage footprints. Cell was overshooting

approx 5Km,Also observed that KAT1007 was off-air during the time of drive test once the site up,issue will be resolved. Suspected hilly terrain on KAT110 or required down tilt.


4/25

Dropped Event 3Call drop observed on KAT811A(SC-314) observed good RF condition. Abnormal release call

observed.


5/25

Dropped Event 4Call drop observed on KAT709B(SC-384) observed good RF condition. Neighbor(KAT1105 SC287)

addition required as observed KAT1105 SC287 was in detected set with good RF footprints.


6/25

Dropped Event 5Call drop observed on KAT1082C(SC-091) observed with low coverage footprints.

Neighbor(KAT715C SC179) addition required as observed KAT715C SC179 was in detected set.Need to check the orientation of KAT715C SC 179.Observed high BLER(greater than 10%).


7/25

Dropped Event 6Call drop observed on KAT1078A(SC-415) observed with low coverage footprints. Need to down tilt

on KAT1078A(SC-415), which was serving from approx 6Km .


8/25

Dropped Event 7Call drop observed on KAT966A(SC-262) observed with low coverage footprints. Need to down tilt

on KAT966A(SC-262), which was serving from approx 5.8Km .


9/25

Dropped Event 8Call drop observed on KAT941B(SC-262) observed with low coverage footprints. Need to down tilt

on KAT941B(SC-262), which was serving from approx 5.5Km .Neighbor addition required KAT1088SC-354 for better optimization.


10/25

Dropped Event 9Call drop observed on KAT904C(SC-58) mainly due to overshooting issue,with low coverage

footprints. Need to physical optimization on KAT904C(SC-58), which was serving from approx4.5Km .


11/25

Dropped Event 10Call drop observed on KAT811A(SC-314) observed good RF condition. Abnormal release call

observed.


12/25

Dropped Event 11Call drop observed on KAT1080C(SC-159) with low coverage footprint mainly due to handover

issue. KAT1080C(SC-159) was overshooting need to physical optimization on KAT1080C(SC-159).Neighbor addition required KAT1080C(SC-159).


13/25

Dropped Event 12Call drop observed on KAT988C(SC-011) due to abnormal call release also & observed high

BLER(greater than 10%) during the time of drop.


14/25

Dropped Event 13Call drop observed on KAT988C(SC-011) due to abnormal call release also & observed high

BLER(greater than 10%) during the time of drop.


15/25

Dropped Event 14Call drop observed on KAT784A(SC-011) due to lack of dominant server .Low cover footprint

observed near the drop.

UMTS CALL SETUP FAILURE

Event Analysis


17/25

Call Setup Failure 1 & 2Call Setup failure observed on KAT744C(SC-254) mainly due to low coverage(which is served from

.700 Km) ,need to served KAT1074 which was off-air during the time of drive test once siteradiating issue will be resolved.


18/25

Call Setup Failure 3Call Setup failure observed on KAT872B(SC-26) mainly due RRC procedure has not established

the radio connection(RRC signaling has timed out. This is controlled by the T300 & N300parameters).Need to check timer values.


19/25

Call Setup Failure 4Call Setup failure observed on KAT933B(SC-404) with good RF foot prints. Abnormal cause

observed.


20/25

Call Setup Failure 5,6 &7Call Setup failure observed on KAT1057C(SC-461) with good RF foot prints. Abnormal cause

observed.


21/25

Call Setup Failure 8 & 9Call Setup failure observed on KAT1057A(SC-460) with good RF foot prints. Abnormal cause

observed.


22/25

Call Setup Failure 10Call Setup failure observed on KAT701C(SC-290) mainly due to low coverage(which is served from

1.5Km) ,need to served KAT1057 SC-460.Physical optimization required on KAT701.
