The basic technological components of a cellular telephone system are radio transmission technology and computer technology. A cellular telephone system has two basic functions; it must locate and track the mobile stations (MSs), and it must always attempt to connect the MSs to the best available base station(s) (BS(s)). The latter task requires the continuous evaluation of the radio link quality with the serving BS(s), and the radio link quality with alternate BSs. This monitoring is performed by a computer system that uses knowledge of the link quality evaluations, in addition to the system topology and traffic flow, to decide upon the best BS(s) to serve a particular MS.
