Patent ID: 7840219

Claim:
A method for selecting a subset of sites within a whole set of candidate sites for activating one or more radio stations in a telecommunications network, comprising the steps of: building an initial solution comprising a subset of sites obtained by starting from a potential network configuration comprising as active the whole set of candidate sites, wherein the initial solution comprises compulsorily active cells corresponding to already active cells in the physical network; and optimising the initial solution by activating “inactive” sites and/or deactivating “active” sites, in order to minimise a predetermined cost function for the solution, wherein the predetermined cost function includes a term pointing out the presence of pilot pollution in the system, the term including a ratio between global traffic in pilot pollution associated with a set of active cells in an examined solution and maximum pilot pollution that can be found in the potential network configuration, and wherein at least one of the “active” sites is deactivated based on the term pointing out the presence of pilot pollution, said steps of building and optimising the initial solution being adapted to define solutions having a geographic coverage wider than a predefined minimum coverage area and being adapted to manage an amount of traffic greater than a predefined minimum value of expected traffic.
