ABSTRACT:
In order to control access from mobile terminals in a code division multi-access communication system, a terminal communicating with one of base station measures data relating to quality of a downlink signal during a predetermined time interval to inform the base station of downlink signal quality. The base station also measures data relating to quality of an uplink signal during the predetermined time interval to produce uplink signal quality data. A base station control device determines from the downlink signal quality data and the uplink signal quality data, communication quality within the the service zone of the base station, and sends an access confinement signal to the base station when the communication quality is determined to be bad. Thus, the base station processes now incoming calls to and from other mobile radio terminals as busy.
