Key Scenarios and implications for WINNER II

WINNER II D6.11.2 v1.02.5 Traffic load scenarioWhile the location scenario describes the relative user distribution and use of different services for aparticular location context, the traffic load scenarios further augments this into the absolute traffic loadexperienced. Therefore user density information is required.Traffic load scenarios (TLS) are used to describe the unrestrained end user traffic and the correspondingbehaviour of the network. TLS therefore refer to the expected nature of the traffic offered to the network,not the actual traffic characteristics over the air interface. No impediment to the build up of traffic isconsidered in the description of the TLS in this document.2.6 Deployment scenarioDeployment scenario comprises relevant features of the environment where the WINNER system is to bedeployed (e.g. building density and height, user density, mobility, etc.), and associated physicaldeployment characteristics used for the technical solution provided by WINNER (like antennas position,number sectors per BS, frequency, bandwidth, duplexing, physical layer mode, cell layout, etc.)[WIN2D6131]. Furthermore the available alternative radio access technologies (and assumptions relatedto their ownership, service offering, and type of co-operation) within the considered area are part of thedeployment scenario summarises key questions addressed and results obtained by the different scenariotypes.The key characteristics of the locations are: physical characteristics of the place, such as building height,building density, their distribution, etc 1 .Table 2.1: Summary of Considered Scenario TypesUserScenarioUsageScenarioLocationScenarioTraffic LoadScenarioDeploymentScenarioKey Question Applicable for Averaging ResultsWhich services areneeded by a user in aparticular role andcontext?How is a particularservice typically used?Which service mix andusage pattern results fora user population in aparticular locationcontext?Which userdistribution, density,and absolute trafficload are generated in alocation scenario?Which technicalsolutions are deployedin a particular locationscenario?Single userSingle serviceand device typeSingle locationSingle locationSingle locationInstantaneousexamplesAveraged overtimeAveraged overtime and usersAveraged overtime and usersAveraged overtime and usersServices peruser type, roleand contextTypical usageconditions of aserviceService mix,mobility, userdistributionUser density,traffic loadDeploymentparameters1 These characteristics are valid for the deployment and location scenarios. The difference is that the deploymentscenario refers to the availability and adoption of the technology in that particular area, while the location scenariorefers to the presence of a potential user of this technology. The connection is that if a location scenario ischaracterised by high user density it would mean that it can become a good deployment scenario driver.Page 10 (41)
