Through counts the establishment service model to the user use service intensity, including service type, service characteristic parameter, service load bearing and service quality objectives 4 aspects. The telephone traffic model is the network planning foundation, model standard the immediate influence to the entire network plan effect. Regardless of being the electric circuit territory or groups the territory, 2G and in the 3G telephone traffic model's establishment and the computation, the principle is the same, the 3G telephone traffic model knowledge has made some supplements according to the 2G service characteristic, therefore the 2G telephone traffic distribution characteristic may take forecasts the 3G telephone traffic distributed basis. Someone in the city plan the dutyfactor is 0.1 service: The WAP browsing, the electronic transaction, the WWW service equivalent is WWW the service model, the dutyfactor is 0.6 above service: The downloading class service, the low-speed data service, EMAIL, the photography picture carries on the transmission, the video frequency fragment transmission, the position/guidance/information service equivalent is the EMAIL service model, establishes the equivalent service distribution model then to estimate the capacity. After the service model analysis method has the Equivalent Erlang, Post Erlang-B, Campbell, Stochastic knapsack 4 kinds.After the link budget determined approximately satisfies the cover goal to need the base depot quantity, simultaneously after the capacity estimate, obtains in satisfies the base depot quantity which the capacity goal under the premise needs, compared with the satisfied cover demand and capacity demand base depot quantity, choice big takes the preliminary cloth station quantity. And passes the over-carriage site selection, definite base depot geographical position.
