Latest Patents

Ozu's latest patents include a mobile communication system and a mobile radio telephone system. The mobile communication system comprises a switching station, base stations to constitute respective zones, and mobile stations moving in a service zone formed by the communication zones. Plural base stations exist in one communication zone, and one specific channel among control communication channels is allocated to one of the base stations. The mobile station transmits a general communication request using one specific channel during the request of the general communication. Alternatively, the control communication channel is allocated only to one station among the base stations. The mobile station has a circuit for measuring the signal-to-noise ratio, and if the signal-to-noise ratio is deteriorated, a signal indicating this state is transmitted to the switching station.

The mobile radio telephone system features multiple base stations controlled by a single line control unit. All base stations use a single common control channel in addition to their voice channels to communicate with a mobile station. If a calling signal from a mobile station is received by two or more base stations at once on the common control channel, the base station with the highest received signal level is selected. If voice signal quality becomes degraded during a call, the call is handed off to the base station with the highest received signal level.
