Patent attributes
The present invention provides a method for optimization of the configuration of a hierarchical network having a first hierarchy level (LEVEL(j−1)), a second hierarchy level (LEVEL(j)) next below the first level, and a third hierarchy level (LEVEL(j+1)) next below the second level, each level comprising nodes (RNC's, HUB's, RBS's) each of which, in level other than the lowest, receives traffic from a cluster of nodes (HUB's, RBS's) of the level next below. The method comprises first determining an initial arrangement of nods (RNC's, HUB's, RBS's) in each of the levels other than the highest, allocating respective initial clusters of nodes (HUB's, RBS's) of that level to the nodes (RNC's, HUB's) of the next higher level, and performing optimizing iterations until they result in no changes in number, disposition and allocation of nodes (RNC's, HUB's, RBS's) over predetermined number of iterations.
