A technique to balance the load across a CDMA network and hence increase its capacity for a given network grade of service (GoS). The technique applies varying uplink and downlink attenuation factors to the cells in the network, in order to change their effective coverage area. This has the effect of changing their load (or carried traffic) and hence the level of interference experienced by the cells. In this way, the carried traffic is forced to be redistributed uniformly across the cells and is of particular importance in a non-homogeneous network. The level of attenuation applied can be determined using an adaptive/optimisation algorithm either dynamically in real-time at network level or as part of the radio planning process of a CDMA/UMTS network. The source of data used to obtain the attenuation factors may be derived using system simulation and/or real network data. |
