Planning tasks & network- Pre-planning activities are high especially when operator is Greenfield or deploying a new technology - Main focus in existing networks are in coverage & capacity as well as configuration planning- Optimisation is always recommended to be done and kept as a very important task of network operation10 RN31543EN50GLA02014 Nokia Solutions and Networks.

Radio Network Dimensioning process Basics Dimensioning process can be split in high level steps: Input data: has big influence on whole result Cell Plan: needs to follow customer input & system performance UTRAN Network Plan:needs to follow customer requirements and also detailed mapping to planned network conditions UTRAN Final Network: is the result from the iterative analysis of inputs, performance values and also area & requirement mapping Input Data Cell Plan Fixed Network Plan - UTRAN Final Network UTRAN 13 RN31543EN50GLA02014 Nokia Solutions and Networks. All rights reserved. Input Data Input data includes for example: Traffic model & capacity requirements Coverage Requirements Quality Requirements - similarly customer might have special requirements (e.g. road, train coverage) - when number of sites is fixed, the traffic model, capacity/coverage and quality requirements are not used as input - More as an output of estimation (i.e. what can be achieved with X number of sites) 14 RN31543EN50GLA02014 Nokia Solutions and Networks.

Traffic Model Nokia StandardNOKIA Standard Traffic Model (Basic Assumptions) can be used: - purpose of having a default traffic model is to have information about the traffic demand available if there is no detailed traffic model provided for network dimensioning- NOKIA Standard Traffic Model reflects average situation in real networks and is defined: - assuming a standard subscriber - using all accounted services in parallel the service split is applied on a traffic demand basis (nosplit on a subscriber basis)UMTS Traffic Evolution: the current NOKIA view on the evolution of traffic demand for a set of identified key services in UMTS. These key services considered in the traffic model are: Speech service Data services like web browsing, email or file download Video telephonyUMTS Traffic Evolution is based on the traffic snapshots from commercial networks and internal assumptions for Subscriber traffic growth
