RNO (Radio Network Optimization):

RNO is very useful tool to:

1- Collect measurement data about all calls for uplink and down link in the

selected cells during specific time

2- Analyze the reports based on the measurement data and gives

recommendations on how to configure the GSM network

3- Implements those changes with or without user interaction

All of those can be achieved by five simple programs:

1- MRR: Measurement Result Report.

2- NCS: Neighboring Cells Support.

3- NOX: Neighboring cells Optimization eXpert.4- FAS: Frequency Allocation Support.

5- FOX: Frequency Optimization eXpert

6- TET: Traffic Estimation Tool.

MRR (Measurement Result Report)

MRR is used to collect the measurement data of both uplink and down link of all the

calls of MSs located in specific cells by monitoring:

1- RXQual UL

2-

RXQual DL3- RXLevel UL

4- RXLevel DL

5- Timing Advance (TA)

6- Path Loss UL

7- Path Loss DL

8- Power Rediated from BTS

9- Power of MS

MRR Main Window

MRR Can be used for

1- Find out the cells with Bad Quality

Example:

This is accumulating Histogram showing the percentage of samples for

RXQual DL. And for this example we can see that the 25% of samples have Bad

quality (>5), which is not acceptable rate.

2



This is a similar Histogram about the Up Link Quality, which gives us the ability to

specify the cells, which need optimization or drive test.

This a histogram of TA through which we can find the unnatural coverage distribution

of the cell

3



The last chart is the RXLevel Histogram which give us Over View for the level in the

rea if it's acceptable or not.

rk and discover the unnatural behavior of the cells

2- Monitoring the New added Sitemplementation of a new feature to

e cells and follow up the customer

5- some optimization to a specific cells and

6- e cells that are shooting too far

8- ion

a

MRR can be very useful for this Implementation:

1- Monitoring the Netwo

3- Making a comparison before and after the i

the Network Like HR for example

4- Find out the trouble shooting of th

complains

Find out the effect of implementing

monitor their behavior before and after the optimization

Discover th

7- Discover the unbalanced power budget for some cells

Discover the cells which need or don't need power reduct

NCS (Neighboring Cells Support)

sed to analyze the Neighboring cell relation by measuring the BCCH signalNCS is u

strength level.

Examples:

This Chart gives us good idea about the existing and missing neighbors.nd by going back to the NCS cell report we can find the Name of the missing

ength is

A

Neighbor and an idea about how many times the new frequency signal str

stronger than the serving cell.

And this idea is clear in the next chart:

5



NOX is a tool, which is built on the data collected by NCS to give us the suggestions

for adding missing neighbors and removing unnecessary neighbors

1-ADD Neighbors

6



2- Remove Neighbors

NCS is very useful for:

1- Find out the missing neighbors

2- Have an idea about the traffic relief from the serving cell to this new neighbor

NOX is useful for giving us over view on the missing and adding neighbors, and

allow us to applying the suggestions of NCS and NOX automatically on the Network

Or by schedule-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.

FAS (Frequency Allocation Support):

FAS is used to measure the uplink interference and estimate the down link by using

BA list for generate ICDM (Interference Cell Dependency Matrix):

Interference is measured in the idle mode for one time slot so there is no problem for

SFH or BBH

7



FAS main window

Examples:

FAS cell report is a powerful report gives you all measurements about the interference

existed on the uplink for all the frequencies on the studied cell, and it suggests new

frequencies with low interference on the uplink.

8



Through FAS cell report chart, the results can be clearly to observe.

FAS ICDM report:

FAS-ICDM calculates the Co & Adj interference between two cells if they have Co &

Adj frequency, and these calculations are done irrespective of the frequency plan

FAS can be very useful for various implementations:

1- Discover interfered frequencies on cells

2- Find replacement frequency for interfered cells

3- Discover swap sectors from FAS-ICDM

4- Build Interference Matrix for Planning tools like TCP

5- Find new frequencies for new TRUs

6- Find the worst frequency to eliminate when removing TRUs

7- Frequency plan for new sites8- Optimize the frequency plan

9



FOX (Frequency Optimization eXpert)

FOX recording is executed both on the UL and DL in the same way as a FAS

recording, the use of FOX adds on help for analyzing the result and improving thenetwork manually or automatically.

In recommendation mode, FOX suggestion reallocations of frequencies and the user

can accept reject or change the suggestions before the reallocation is executed in the

network.

When running a FOX recording in automatic mode the reallocation is implement

Automatically.

10



Planning area

Planning Areas are a way for determine all the changes we need for optimizing the

network regarding changes in neighboring relations or Frequency reallocations and

can be easily implemented to the network by CNA (Cellular Network Administration)

TET (Traffic Estimation Tool):

By using the TET and TEMS transmitter we can test the frequency, which apply on

the transmitter.

Test frequency is added to the BA-lest of the surrounded cells (which is included in

the cell set)_this is done by TET_, and after that we can see from theTET the relief

load from the surrounded cells, which occurred, by the transmitter.

So by this tool we can test the better frequency to use, antenna type and height, thelocation of the site (Micro or Macro), and the transmitter output power

Note: the BCCH can’t be changed when the record has been scheduled.
