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
*OMC: Operation and Maintenance Centre

User Profile Traffic Maps
2 types available:
•
Vector map (lines, polygons or points) with:
•
Raster map in which:
•
a user profile,
each pixel is assigned a user profile environment
•
a mobility type,
•
•
• •
a subscriber density (or no. of subscribers) assigned to each of them
User profile densities
• • •
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) Clutter weighting and indoor ratio per clutter class to get an accurate user distri bution
List of user profiles with associated mobility and density
User Profile Traffic Maps
Importing a User Profile density based traffic map (1/2)
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 Option “by field”: selection of the corresponding field in the imported file, for each data (user profile, mobili ty, density) Detailed information per polygon or line
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)
Possible clutter weighting and indoor/outdoor ratio per clutter class in order to get a more accurate user distribution
User Profile Traffic Maps
Same management features as vectors Attributes listed in a manageable table Sort and filter criteria on vector display Generic display dialog Access to any single vector property Possibility to export traffic map • Mif/mid, shp, agd formats
User Profile Traffic Maps
Creating a User Profile environments based traffic map
To create a map from scratch
8-bits raster file import Supported formats : bil, tif, bmp
Selected Environment
Draw polygon
Delete polygon
User Profile Traffic Maps
Same management features as clutters Multi-layer/multi-resolution management (WYSIWYG) Map display • Transparency level and visibility range
Statistics per environment Possibility to export traffic map • Bil, tif, bmp formats

Subscriber Database
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
Example: UL and DL throughputs, for each defined service
Sector Traffic Maps
Map creation (1/3) Four types of traffic map per sector
To create a map from scratch Based on a service area study by transmitter (defined and calculated) to obtain cells’ coverage
*.agd format file import
Sector Traffic Maps
Map creation (2/3)
Defined Transmitters
Coverage by Transmitter (Mandatory)
UL and DL throughputs (or number of users) for each sector
List of all defined services
Sector Traffic Maps
Map creation (3/3)
Map type selection:
• Throughputs, • Number of active users, • Number of users per activity status
Distribution of Mobility type used in the map
Distribution of Terminal used in the map
Possible clutter weighting and indoor/outdoor ratio per clutter class in order to get a more accurate user distribution
Sector Traffic Maps
Management features Traffic description in a manageable table Sort and filter criteria on display Generic display dialog Possibility to export traffic map • Agd format

Subscriber Database
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
Density of active users (number of users/km²) on each pixel
Users can be inactive, active UL, active DL or active UL+DL • One map per activity status
User Density Traffic Maps
Map creation (1/2)
Five types of traffic map per User Density
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)
User Density Traffic Maps
Map creation (2/2)
Activity status to be considered in the simulation
Percentage of each Terminal used in the map
Percentage of each Mobility type used in the map
Percentage of each Service used in the map Percentage of indoor users per clutter class during the Monte-Carlo distribution
User Density Traffic Maps
Management features of user density based traffic maps Generic display dialog Statistics Possibility to export traffic map • Bil, bmp formats

Subscriber Database
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 • ...
