UMTS Bearers in Asset3gUMTS Bearers in Asset3g

• In Asset3g there are UL and DL Bearers

• A Bearer is defined by:• It’s Bitrate

• Eb/No Value

• Soft and Softer handover gains

• And other parameters…

• Configuration → Bearers → UMTS


Bearers Tab 1Bearers Tab 1

• Name Bearer and define UL or DL direction

• The Air Interface bitrate is used when calculating processing gain and Signal to Noise ratio

• The User bitrate is used in calculating cell throughput for different services and in throughput reports

• Air interface and User interface values are typically set to be the same


Bearers Tab 2Bearers Tab 2

• Control Overhead % may be defined here:• Vendors normally absorb this value on the recommended

Eb/No values and Activity factors. e.g. 58% for voice, with 8% being the OH. In this case, set this value to 0

• Set the Resource consumption in number of physical channels


Noise Model and Eb/No Speed DeltaNoise Model and Eb/No Speed Delta

• Define noise model: typically Gaussian

• Define link Eb/No• Frame Error Rate comes from previous tab

• You can also define Eb/No with diversity

• Define Eb/No speed dependency• This is the offset in the Eb/No requirement at different speeds


Additional DL optionsAdditional DL options

• DL Eb/No target reduction• Define the reduction on the Eb/No target for different speeds

and different Ec/Io values

• Max Tx Power in dBm• This is the max Tx power that may be allocated to this Bearer

• If this is exceeded there’ll be a “DL Eb/No range failure”


Additional UL optionsAdditional UL options

• Power Control Headroom• Establishes a relationship between the different speeds and

Power control headroom requirements

• Also sets the Average Power Rise that this causes

• TXP Gain (Transmit Power)• This represents the gains obtained from soft and softer

handovers

• Results in reduction on the Tx Power reduction on the UL


Additional UL optionsAdditional UL options

• PR Gain (Power Rise)• Represents the power variations on the UE for the Uplink

• As Eb/No increases due to soft or softer handover there is less power variations

• PCH Gain (Power Control Headroom)• Represents the PC Headroom required at different speeds and

at different Eb/No values

• As Eb/No increases due to soft or softer handover there is less need for Power Control Headroom


Services in Asset3gServices in Asset3g

7- The Static Analyser7- The Static Analyser

Section 7 – The Static Analyser

Static AnalysisStatic Analysis

• Allows quick determination of key parameters

• Uses a deterministic algorithm: running the analysis several times yields the same results

• It provides per Service and per Carrier measurements

• You need to have a pathloss prediction in memory


Static Analysis options 1Static Analysis options 1

• Arrays → Static Analysis → UMTS

• Simulation Resolution

• Number of covering cells:• 6-18 to account for effect of surrounding cells (1st or 2nd tiers)


Static Analysis options 2Static Analysis options 2

• Select Pilot Pollution threshold• Any Pilot signal that has an Ec/Io level higher than this

threshold, and it’s not part of the UE’s active set, will be considered a polluter

• Power Control Std Deviation

• Intra-site/inter-site correlation coefficient: • They are not used in the calculation of noise rise or DL power

on the cell, but they are used during the passive scan stage of Static Analysis


Cell Loading ParametersCell Loading Parameters

• “Get values from the database” goes to the site database Cell Parameters tab and obtains UL Noise Rise and DL Tx Power

• If UL Noise Rise and DL Tx Power are set to 0, this is equivalent to an unloaded condition

• “Calculate the values” requires a traffic raster in memory to calculate the above values

8- The Monte Carlo Simulator8- The Monte Carlo Simulator

Section 8 – The Monte Carlo Simulator

Monte Carlo AnalysisMonte Carlo Analysis

• It’s a more complete form of Static Analysis

• More accurate than Static Analysis

• Takes a large number of randomised snapshots of network performance for different terminals over time

• In these snapshots, the UEs are in statistically determined positions and generated independently for each snapshot


Monte Carlo Static SimulationMonte Carlo Static SimulationSection 8 – The Monte Carlo Simulator

MC Analysis: InitialisationMC Analysis: Initialisation

• The number of terminals in an active session in a pixel is determined using a Poisson distribution with a mean given by the number of terminals in the traffic array

• At the start of the snapshot the mobile and cell powers are initialised to zero and these are then used to initialise the noise on the uplink and downlink

• Other parameters such as power control error are set randomly on every terminal


MC Analysis: Testing procedureMC Analysis: Testing procedure

• The first terminal in the list is tested for failure conditions. If it does not fail, then its Tx power, and the Tx power of the cells to which it is connected, are modified

• The next terminal in the list is then tested for failure conditions and so on

• When the entire list has been tested, the simulator returns to the first terminal and repeats the process. This continues until convergence is reached


MC Analysis: Reaching convergenceMC Analysis: Reaching convergence

• When convergence is reached, the results of the snapshot are appended to the results of the overall simulation

• The simulation moves on to the next snapshot

• When the simulation has completed all the specified snapshots, you can view your results using the arrays or view a summary of the data or reports


The Monte Carlo SimulatorThe Monte Carlo Simulator

• Arrays → Simulator → Monte Carlo Wizard → UMTS

• Needs a traffic raster in memory to run

• For Jersey, and 7 sites, it takes around 750 snapshots to reach a 95% confidence interval of 2dB


Simulation ResolutionSimulation Resolution

• The simulation resolution determines the dimensions of the output arrays and produces a grid on which the terminals will be placed

• When the simulation resolution is higher than the resolution of the traffic raster and the coverage predictions, then these would have to be converted

• It is advised that all these resolutions are equal because in the case of large areas with a high number of sites this process may be time consuming


Number of covering cellsNumber of covering cells

• In general for most environments at least all the first order neighbours must be considered, while the inclusion of second order neighbours should be considered to ensure the accuracy of the results

• For high cell densities (urban areas) it would not sensible to set this value low because a lot of interference coming from many cells is being ignored

• In rural areas setting this parameter very high would result in a very slow simulator process


Power Control Standard DeviationPower Control Standard Deviation

• The standard deviation for power control error parameter controls the distribution of the power transmitted by successfully served terminals

• A standard deviation value of 0 implies the Eb/No value for each successfully served terminal is achieved perfectly

• In reality this is not the case as imperfect power control produce a log normal distribution of achieved Eb/No values at a cell.


Running the simulation 1Running the simulation 1

• Simulation Resolution & Number of covering cells:• 6-18 to account for effect of surrounding cells (1st or 2nd tiers)

• Select Pilot Pollution threshold• Any Pilot signal that has an Ec/Io level higher than this threshold,

and it’s not part of the UE’s active set, will be considered a polluter

• Power Control Std Deviation

• Intra-site/inter-site correlation coefficient



• Select the terminals to simulate. If there are no terminals with a traffic raster this screen will be blank

• You could split the simulation into several regions

• You could distribute the processing load amongst several machines

• Select arrays to output



• You could save partial results every “X” minutes

• Define number of iterations per snapshot, 10 is a good number

• Define Max power change % to consider that the simulation snapshot has reached convergence



• Decide whether to use a passive scan terminal:• The passive scan terminal is a virtual terminal that is positioned

in all the pixels of the simulation area after the snapshot has converged

• Predicts the coverage for a particular service and produce a coloured array

• This slows the overall simulation process

• Does not affect the reports/results

• If desired, run a scan every 10 snapshots

• Review the summary of parameters


Simulation Control PanelSimulation Control Panel

• Decide the number of snapshots to run• If using this option, run at least 1000 snapshots

• Decide if running to a 95% confidence interval

• Click “Run” and wait

• At the end Save the results


Pausing and restarting the simulationPausing and restarting the simulation

• You can restart or pause a simulation using the Monte Carlo Simulation Control Panel dialog box. If you want to re-run the simulation…

• With new parameters: close the MC simulator and reopen it to set up new parameters

• With the same parameters: click the “Clear Results” button and click “Run” again

• To pause a running simulation click the Stop button

Key Per Server Arrays: Best ServerKey Per Server Arrays: Best Server

• This array displays the cell that can offer a coverage probability above the specified threshold in the settings.

• The coverage threshold is specified by the user and could correspond to the minimum GoS required


Coverage ProbabilityCoverage Probability

• This array shows the coverage probability for every pixel in the simulation area.

• Without using the passive scan terminal, it shows us the percentage of users that attempted access to the network and were actually successful


Coverage Probability for the Nth Best ServerCoverage Probability for the Nth Best Server

• This array displays the individual coverage probabilities for the attempts that have been made on all the cells starting from the one that offers the best coverage but continuing to the Nth best server

• What we expect to see is that the coverage probability of the first server is a lot higher than the ones of the second and so on

• We would like to have a dominant best server in every area for optimum distribution of the resources


Downlink achieved Eb/NoDownlink achieved Eb/No

• The value on the pixel to be displayed here is the mean Eb/No across all the users on that pixel that have made successful access attempts

• Ideally, the Eb/No for a connected user the value would be exactly the one entered in the bitrates. However this is going to vary if we introduce power control error

• The variation on the mean achieved Eb/No is directly related to the standard deviation value of that error which we input in the simulator wizard


Soft Handover Arrays 1Soft Handover Arrays 1

• Mean number of soft/softer handover cells:• Shows for every pixel the mean number of cells apart from the

primary one that are engaged in soft/softer handover

• Mean size of active set• Shows the mean number of cells that a terminal would be

connected to on each pixel including the primary connection cell


Soft Handover Arrays 2Soft Handover Arrays 2

• Most probable handover type• Displays the type of handover that will take place provided that

there is a handover happening in that pixel.

• Probability of soft/softer handover• Shows the percentage of terminals, out of the total successful

primary connections, that were able to connect to more than one other cells of the network


Probability of Low Ec/IoProbability of Low Ec/Io

• The level of the pilot Ec/Io is the primary constraint that has to be met on a carrier before a connection to the network can be established

• There is a combination of two primary reasons that result in such a failure: the path loss and the experienced noise level


Key Per Carrier Arrays: Best Server by PilotKey Per Carrier Arrays: Best Server by Pilot

• This array provides the means to quickly optimise the coverage of a network by displaying the areas of pilot coverage


Pilot Ec/IoPilot Ec/Io

• This array displays the level of the primary connection constraint to the network

• Selecting an appropriate pallet would result in quickly identifying areas of coverage for multiple types of terminals with different required Ec/Io

• When it is low then it is necessary to re-optimise pilot coverage


Mean Number of Pilot PollutersMean Number of Pilot Polluters

• This array will show us for every pixel in the simulation the total number of cells that do not belong in the active set and at the same time have a Ec/Io above the threshold specified in the simulator wizard window

• It is one very important array as we can easily identify the existence of downlink interference in areas where other cells are supposed to be offering service to a user as members of the active set


Pilot CoveragePilot Coverage

• The Pilot Coverage array displays the pilot strength in dBm for the selected carrier and is useful when determining pilot interference

• This array shows the same information as the Pilot Strength array, but the powers can be grouped into categories of pilot strength


The Pixel Analyser 1The Pixel Analyser 1

• Allows the analysis of the simulation results on a selected pixel

• There are two pixel-analyser modes:

• Hot Tracking (Red): a dynamic analyser. Changes as you move the mouse over the 2D view

• Pixel Select (Black): click on a pixel to display the available info


The Pixel Analyser 2The Pixel Analyser 2

• In the Pixel Analyser, select the layer whose information you wish to view

• Click Pixel Column Details and choose the items and thresholds, if applicable

• Click Array Row Selection and choose the arrays you want to view in the Pixel Analyser

• Some key parameters include:

• Code re-use distance:

• You can specify the minimum distance between each cell within the plan to ensure they have a different code

• Consider other cells under the same Node B:• Selecting this check box will ensure that the cells on the same

Node B regardless of carrier are all allocated unique Scrambling Codes

The Packet QOS Analyser 1The Packet QOS Analyser 1Section – The Packet QoS Analyser

• You can predict the packet traffic delays by using the Packet QoS Analysis

• It is a DL cell level simulation, with 10 ms (single radio frame) resolution

• The packet transmission delays through a cell are modelled by a queuing system, which has a time-series of packet traffic offered to it.

• Arrays → QoS Analysis Wizard

The Packet QOS Analyser 2The Packet QOS Analyser 2Section – The Packet QoS Analyser

• After running the simulation for a specified period of time, you can view the results as graphs and spreadsheets

• The graphs include the cumulative delay distributions of the packet services on each cell, enabling you to read off percentile delays.
