Abstract
Abstract In a control circuitry for a two-way mobile radio voice/data shared communications system including a plurality of mobile stations with data and voice terminals, a base station, a dispatching station for voice and data, a voice/data processor interposed between the voice/data dispatching station and the base station, there is provided means for enabling transmission and reception of inbound and outbound voice and digital data signals between the base station and the mobile stations selectively to effect full-duplex voice/data shared communications.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A control circuitry for a two-way mobile radio voice/data shared communications system including a plurality of mobile stations with data and voice terminals, a base station, a dispatching station for voice and data, a voice/data processor interposed between the voice/data dispatching station and the base station, said control circuitry including: means for enabling the base station to receive the inbound voice signal from a mobile station and rebroadcast the inbound voice signal to the other mobile stations, means responsive to the inbound voice signal for inhibiting transmission of digital data signal from any of the mobile terminals to the base station, and means for independently transmitting outbound digital data or voice signal from the dispatching station.
Claim 2
Dependent Claim
116 words
A control circuitry for a two-way mobile radio voice/data shared communications system including a plurality of mobile stations with data and voice terminals, a base station, a dispatching station for voice and data, a voice/data processor interposed between the voice/data dispatching station and the base station, said control circuitry including: means for enabling the base station to receive the inbound voice signal from a mobile station and rebroadcast the inbound voice signal to the other mobile stations, means responsive to the inbound voice signal for inhibiting transmission of digital data signal from any of the mobile terminals to the base station, and means for independently transmitting outbound digital data or voice signal from the dispatching station.
Claim 3
Dependent Claim
88 words
The control system according to claim 1, including: means for enabling the base station to receive an inbound digital data from a mobile station and rebroadcasting the inbound digital data to other mobile stations in the absence of the inbound voice signal, means responsive to the inbound digital data for inhibiting transmission of any digital data from any other mobile station, and means for overriding the rebroadcasting of the inbound digital data in order to permit transmission of voice signals to the mobile stations from the dispatching station.
Claim 4
Dependent Claim
89 words
The control circuitry according to claim 2, including: means for sending out an outbound voice signal from the base station to the mobile stations, means responsive to the outbound voice signal for inhibiting the transmission of digital data from the base station to the mobile station while the outbound voice signal is being transmitted from the base station to the mobile stations, and means for permitting transmission of digital data or voice from any of the mobile stations to the base station independently of transmission of outbound voice signal.
Claim 5
Dependent Claim
63 words
The circuitry according to claim 1, including: means for permitting transmission of digital data to a mobile station from the base station, and means for overriding the outbound digital data transmission to permit voice transmission from the dispatching station to the mobile stations while permitting transmission of inbound voice or digital data signals from any of the mobile stations to the base station.
Claim 6
Dependent Claim
89 words
The control circuitry according to claim 1, including: means for sending out an outbound voice signal from the base station to the mobile station, means responsive to the outbound voice signal for inhibiting the transmission of digital data from the base station to the mobile station while the outbound voice signal is being transmitted from the base station to the mobile stations, and means for permitting transmission of digital data or voice from any of the mobile stations to the base station independently of transmission of outbound voice signal.
