Abstract

Only an information output from a wireless terminal for mobile unit to a wireless base station is allowed in response to an operation of operating means of the wireless terminal for mobile unit. When only the information output from the wireless terminal for mobile unit to the wireless base station has been allowed by the operation of the operating means, an information output from the wireless base station to the wireless terminal for mobile unit is allowed in response to another operation of the operating means. The wireless terminal for mobile unit is constructed so as not to respond to another operation of the operating means during the predetermined time since the first operation of the operating means.

Claims

1. A wireless terminal for mobile unit which is mounted in a mobile unit and conducts communication with a wireless base station through wireless, said wireless terminal comprising:

an operating section for starting the communication with the wireless base station; and

a controller for allowing only an information output from the wireless terminal to the wireless base station in response to a fact that the operating section has been operated.

2. A wireless terminal for mobile unit as defined in claim 1, wherein said controller allows an information output from the wireless base station in response to the fact that the operating means has again been operated when having allowed only the information output from the wireless terminal to the wireless base station in response to the fact that the operating section has been operated.

3. A wireless terminal for mobile unit as defined in claim 1, wherein said controller allows an information output from the wireless base station in response to the fact that the operating section has again been operated a predetermined period of time after the operating section has been operated when having allowed only the information output from the wireless terminal to the wireless base station in response to the fact that the operating means has been operated.

4. A wireless terminal for mobile unit as defined in claim 1, wherein said controller allows a voice information output from the wireless base station in response to a voice output request message sent from the wireless base station when having allowed only the information output from the wireless terminal to the wireless base station in response to the fact that the operating means has been operated.

5. A wireless terminal for mobile unit as defined in claim 1, wherein said controller allows an image information output from the wireless base station in response to an image output request message sent from the wireless base station when having allowed only the information output from the wireless terminal to the wireless base station in response to the fact that the operating means has been operated.
