BQ Drop percentage & BQ urgency HO is less among all

the SC towns as AFP was

done in Imphal before.

Cluster selection

Following criteria were taken into account:

1.AFP completion2.Less BQ related drops 3.High TCH Blocking (=9.36)4.Uneven traffic distribution among cells

While doing xParameter for only Imphal City, border cells are left unoptimized as neighboring cells of the border cells were not taken into account. As a result of this, area optimization percentage was showing very low value. Therefore we decided to take all the BSCs in which the city is falling. So, we chose to include all the 3BSCs – IMPBSC1,IMPBSC2,IMPBSC3.

in the same or different machines. We just need to configure the connection settings properly from xParameters and ODG modules.

› CM data – C:\Program Files(x86)\Optimi\Optimi Data Gateway\ Optimi Data Gateway\data\Ericsson 2G\cm_data

› PM data - C:\Program Files(x86)\Optimi\Optimi Data Gateway\ Optimi Data Gateway\data\Ericsson 2G\pm_data

› Sector location files – location in the hard drive where you have copied

the file,Collected as per the requirement to run ODG ( Optimi Data

CM data should be in CNAI

format

Step 2.3

1.PM data should be in ASN1 format

2. History size should be (Current Date – starting date

of PM data – 1)

For e.g: Here I have run the ODG on 11/Nov/11,& the starting date of

the PM data is 7/Nov/11,so the History size would be greater than

or equal to 4

› Now ODG creates complete operDB using CM Data ,PM Data & Sector Location file

› This operDB acts as input to the next step i.e. to the main xParameter tool
