CELLULAR NETWORKS WITH SPARE BASE AND SATELLITE STATIONS

摘要

A cellular network includes a control station and a network of base stations installed one per cell with which one or more mobile stations can communicate as they roam through a cell. Redundantly deployed spare base stations are introduced alo ng with the primary base station at a central area of each cell. The redundantly deploye d spare base stations handle new calls when the associated primary base station is overloaded , participate in retransmission of data lost due to degraded channel conditions an d congestion in the network, and assist in handoffs. Primary and spare satellite s tations are deployed in regions marked by hills or valleys to augment the communicative capa bilities of the primary and spare base stations.
