1) RF Optimization tool is designed for Daily Optimization and Troubleshooting tasks of GSM / WCDMA Networks
Network performance management, reporting and monitoring Web tool (logs and stores network parameters), enabling complete understanding of the current and past Network performance.
1) Keeping in mind the Vendor Portability (NSN / Huawei) – Based on report inputs to SQL database
2) Focused precisely on the Optimization / Planning requirement and friendly in use
3) Worst cell are designed to highlight all the problematic cells with reasons on the BSC / RNC main page at Counter lebel
4) Makes all the Consistency check for 2G/3G Networks, and provide the template of Network parameters
5) Parameter comparison provides the vendor flexibility for NSN /Huawei
Web based system – Asp.net (No licensing and Installation of Tool required) - Only requirement is Computer Terminal / Notebook and Web Browsing Software (Internet Explored / Fire Fox / Google crome….)
1) Background Database used is SQL as Primary and some other reports are used in Access format
2) SQL Database required raw Files from reporting suit as I/P
3) Other Database files are processed through Scripts and Macros designed to get desired O/P which can be downloaded from Database page
4) Program is designed in ASP.net (scripting in: C#)
5) To Access to the Tool one need to connect through WiFi Network and can pass the IP Address
http://172.28.106.89/Advancetool/Optimizer/3G/RNC3G.aspx
6) Software requirement : Web Browser, IE6, FireFox, Google crome
7) Adobe Flash player 10 need to be installed to Display the Flash Files
With a Local Server Installed – Tool can be easily connected to INTERNET by ISP and can be remotely used from any place

BSC Daily page shows the Main KPI report (Daily and Hourly) trend
KPI’s are displayed in combinations of related KPI’s as shown in the fig.
e.g. Voice Traffic / DCR , SD Blocking / CSSR
TCH Blocking / HOSR, Data Traffic / TBF Drop rate
It gives the Flexibility to select the Dates for Worst cell Comparison
For Worst cells the flexibility is given to compare the dates.
E.g. Comparison between last two day or comparison between Friday to Friday (Weekend)
In normal practice those cells are considered as worst cells which are top Droppers or worst performer, but generally these worst cells constantly repeated in a BSC/ Network
But worst cells must be those which are degraded suddenly with a Margin,
e.g. if a cell drops 400 Calls/day and it is repeating itself, it is a worst dropper but must not be considered as degraded cell,
now cell which is dropping 50 calls/day and next day it drops 150 Calls it must be highlighted and must be checked for degradation
In these worst cell Graphs all Segments / BTS are displayed in X axis, where as KPI’s are displayed in Y-Axis
Now the two dates which we have chosen are Displayed over each other (Last date is plotted in Blue and previous to that date is plotted in Orange)
In this case if there is any degradation in any Cell will be immediately be Noticed (as we can easily identify the change in Delta)
By putting the Cursor in that Line it will immediately Highlight the Worst cell
In the same methodology here 19 Counter combinations are chosen to check the Network Performance, so that
no reason must be unknown, even any small degradation or change in the Network will be seen clearly and will be noticed
Every single reason is Highlighted at Counter Level for cell Identification
Counters Displayed as worst cells are
Segment Level
SD Blocking TCH Blocking Location Updates T3101 Expired
SD Drop SD Radio Fail HO Failure Intracell HO Failure
BSC Incoming HO Fail MSC Incoming HO Fail Voice Traffic Data Traffic

Comparing Timing advance for 2 weeks same day – Gives an idea if there is any Timing advance or Site coverage
Non BCCH Layer Comparison:
3 weeks Comparison (same day) – NBL Overlapped over each other, easily can find out if there is any shift in NBL due to Hardware issue, NBL Shift due to Antenna change, Tilting etc
Both the Graphs (Counters) gives the flexibility to change the dates accordingly
RNC Daily page shows the all Main KPI for RNC (Daily) trend
KPI’s are displayed in combinations of related KPI’s as shown in the fig.
e.g. For AMR, Voice HSDPA RRC RAB
SHO IRAT HSUPA Congestion
etc………
Total 29 Counters displayed as Main KPI’s for RNC
It gives the Flexibility to select the Dates for Worst cell Comparison
Similar Like what is for 2G same Methodology is applied for WCDMA Worst cells with flexibility date comparison.
E.g. Comparison between last two day or comparison between Friday to Friday (Weekend)
Total 44 Counters are displayed in Graphical form for whole RNC, to check every possible reason of degradation in any cell
e.g. RRC Setup fail , CS AMR CallDrop, AMR RAB Setup fail, RRC Setup fail service
PSRAB Setup Fail HSDPA RAB Fail AMR SHO Fail CS IRAT Fail
etc…….

Most of the counters which are used for Optimization tool are generalized counters and not Vendor specific
To use the same Software the only requirement is to change the Database Connectivity in SQL Server as shown in the fig.
Only the related counters need to be mapped

1) Google EARTH site creations / To develop MIPT features on Google earth
2) 360 Deg – 3D Panoramic view of Site Photographs
3) Voice Command Input for Tool Operation and functioning
4) Chat server-Once client will be logged in to server he will be automatically be logged in into chat server for any online support and discussions
5) More Artificial Intelligence on tool based on previous network actions taken to improve the performance
6) Adding CDMA 2000 1x and WiMax Network Monitoring (One common Platform for Radio Technology)
7) Silver Light application for more Rich display features, 3D View, KPI design flexibility according to user requirement (Work space)
