Abstract

Systems of and methods for providing cellular priority access and topological guidance information to cellular users are described, employing wireless ad hoc network and cellular logic. A centralized aspect of acquiring cell loading information and geographic coordinates is combine with a distributed scatternet forming aspect to enable guidance information to be computed and indicated to the user. The guidance information is reflective of cell loading and congestion status of neighboring cells, as well as the availability of alternative radio resources in the user'"'"'s current cell or neighboring cells. The system may also be employed in redistributing cell traffic among cells to optimally balance cell loads.
