Abstract
In a cellular telecommunications system in which a geographic area is divided into a hierarchical cell structure such that geographically small but high bandwidth-available cells are located in geographically larger cells of less bandwidth-availability, mobile station connections are made based on the bandwidth requirements of the mobile stations together with the likelihood of mobility of the mobile station within the cell structure. For mobile stations that have low bandwidth requirements and are highly mobile (such as telephones) the mobile stations are connected to cells at a cell layer having relatively large geographical areas yet low bandwidth-availability. On the other hand, for mobile stations with high bandwidth requirements, the mobile stations are connected to geographically small cells with high bandwidth-availability. In this way, mobile stations with high bandwidth requirements yet low mobility can obtain the high bandwidths needed for their communications, while mobile stations with lower bandwidth requirements yet high mobility can move through the cell arrangement while minimizing the number of required handoffs.
