Traffic Maps Management
Introduction
Traffic maps are mandatory to generate user distributions used by Monte-Carlo simulations
They can be additionally used to compute Interference Matrices (IM) in 2G networks
3 main types of traffic maps defined in Atoll:
User profile traffic maps • Marketing-based traffic data
Sector traffic maps • Live traffic data from OMC*
User density traffic maps • Population-based traffic data
• 2G network statistics

User Profile Traffic Maps
2 types available:
© Forsk 2014 Slide 5 Confidential – Do not share without prior permission
•Vector map (lines, polygons or points) with: •a user profile,
•a mobility type,
•a subscriber density (or no. of
subscribers) assigned to each of them
User profile densities
•Raster map in which: •each pixel is assigned a user profile
environment •Urban, •Dense Urban, • Suburban, •Rural, •…
User profile environments
User Profile Traffic Maps
Requirements (1/2)
Define User Profiles: • Description of the behaviour of different subscriber categories for given services:
• Terminal used
• Average number of calls (Voice) or sessions (Data) /hour
• Average duration (for Voice services, in seconds)
• UL & DL data volume (for Data services, in Kbytes)
• “Standard User” and “Business User” defined by default in Atoll

User Profile Traffic Maps
Requirements (2/2)
Define Environments: • Economic and social concept used to describe subscriber spatial distribution on
the map
• Each user profile is associated with:
• A mobility type
• A density (number of users with the same profile per km²)

Vector file import
Supported formats: dxf, mif/mid, shp, agd
Example: Format mif/mid
User Profile | Mobility | Subscriber Density
User Profile Traffic Maps
Importing a User Profile density based traffic map (2/2)
You must specify the source of traffic information: • Attributes of polygons/lines/points described in the imported file
• User-definable global information
© Forsk 2014 Slide 9 Confidential – Do not share without prior permission
Option “by value”: selection of a user profile, a mobility, and specification of a density/no. of subscribers Global information for all polygons or lines (here Mobility = 50km/h for all polygons)
Option “by field”: selection of the corresponding field in the imported file, for each data (user profile, mobility, density) Detailed information per polygon or line
Possible clutter weighting and indoor/outdoor ratio per clutter class in order to get a more accurate user distribution

Traffic Maps Management
Sector Traffic Maps
Live traffic data from OMC
Requirements
Define traffic for each sector: • either the total throughput demand per service,
• or the total number of active users per service,
• or the total number of users sorted by service AND activity status
Calculate a coverage prediction by transmitter

Traffic Maps Management
User Density Traffic Maps
Based on population statistics (density of inhabitants, or 2G traffic statistics)
Inputs
Density of users (number of user/km²) per pixel • Can be deduced from population maps and sector traffic maps
Users can be inactive, active UL, active DL or active UL+DL • One map per activity status
© Forsk 2014 Slide 20 Confidential – Do not share without prior permission
Density of active users (number of users/km²) on each pixel
User Density Traffic Maps
Map creation (1/2)
Possibility to: • Create a new map from scratch (thanks to Vector editor)
• Import 16 and 32-bit raster file (Supported formats : bil, tif, bmp, erdas imagine)

Traffic Maps Management
Subscriber Database
Basically used to model fixed user distributions in a network
Rely on Subscriber Lists in Atoll, managed from the Network tab
Supported by the LTE, Wi-Fi and WiMAX modules
Importing Subscriber Lists
Supported formats: .txt and .csv

Example of a Subscriber List:
Subscriber Database
Atoll can perform an Automatic Server Allocation for all Subscribers in a list
A large set of data is then available for each Subscriber: • Reference Cell (Server)
• Channel Powers (PDSCH, PDCCH, PBCH ...)
• Bearers in UL & DL
• Throughputs
• ...
