Dynamic W-CDMA network planning using mobile location

Location assisted dynamic network planning enables an operator to obtain geographic specific performance estimates and automatically redistribute radio resources. Statistical data is gathered in a database and refreshed periodically to create a dynamic distributed planning tool. Since mobile terminals now measure the actual path loss to each location, the uncertainties associated with propagation modelling and geographic databases are removed. Dynamic coverage maps enable base stations to increase (or decrease) their coverage and capacity in areas regularly (or not regularly) visited by subscribers. The base stations also make provision for the additional resources required by high data rate users, possibly through the process of intelligent handover. The concept can be viewed as a fusion of location techniques and network planning. The network subsequently has a powerful self-learning capability and adapts over time to slow variations in the propagation environment or traffic loading conditions. The performance of a number of location techniques is studied and the required location accuracy for dynamic W-CDMA planning determined.
