ABSTRACT:
A server for use by a designated one of a number of mobile units in a cellular communications system including a plurality of cells having different service areas with respect to one another may be selected by, for each of the mobile units, assigning to each cell a category of preference for selection with respect to each other cell within the system, wherein for at least one of the cells, the assigned category of preference associated with a first mobile unit is different from the assigned category of preference associated with a second mobile unit. Then, for the designated mobile unit, the assigned category of preference for each of a number of candidate cells is determined. A first one of the candidate cells is then selected as serving cell for the designated mobile unit based upon whether the first one of the candidate cells has a higher category of preference than another of the candidate cells. Because categories of preference may differ for different mobile units, location-based services, based on categories of subscribers, may be provided. In other embodiments, a radio network may be optimized with respect to varying capabilities of installed radio base equipment.
