Abstract

During the CDPD mode period, RSSI data and battery remaining capacity determination data measured by a hand held phone HHP are periodically transferred to a personal computer PC, and are displayed on an LCD display of the personal computer PC. During the CDPD mode period, status data representing the operation state of the personal computer PC is transferred to and displayed on the hand held phone HHP. Furthermore, during the CSCD mode period, status data representing the operation state of the hand held phone HHP is transferred to the personal computer PC, and is displayed on the LCD display of the personal computer PC.

Claims

1. A mobile communication terminal apparatus comprising:

a hand held phone having a function of exchanging a radio communication signal with a base station via a radio channel; and

a data terminal device which comprises a control unit having a control function of performing a mobile data communication with a data terminal device of a communication partner at least via said hand held phone and the base station, and a modem unit for connecting said control unit and said hand held phone and performing an interface operation for the mobile data communication under the control of said control unit,

wherein said data terminal device comprises status information transfer means for transferring status information representing its own operation state to said hand held phone while a communication mode in which said data terminal device leads connection control with said hand held phone, and

said hand held phone comprises status information display control means for displaying the status information transferred from said data terminal device on a display unit.

2. A data terminal device which comprises a control unit having a control function for performing a mobile data communication with a data terminal device of a communication partner via a hand held phone and a base station connected to the hand held phone via a radio channel, and a modem unit for connecting said control unit and the hand held phone, and performing an interface operation for the mobile data communication under the control of said control unit, comprising:

status information transfer means for transferring status information representing its own operation state to the hand held phone and displaying the transferred information on the hand held phone while a communication mode in which said data terminal device leads connection control of a radio channel between the hand held phone and the base station is set.

3. A hand held phone which is connected to a data terminal device having a predetermined communication control function required for performing a mobile data communication, and has a unction of transmitting transmission data of the data terminal device to a base station via a radio channel, receiving reception data coming from the base station via the radio channel, and transferring the reception data to the data terminal device, comprising:

status information display control means for, when status information representing an operation state of the data terminal device is transferred from the data terminal device while a communication mode in which the data terminal device leads connection control between said hand held phone and the base station is set, displaying the transferred status information on a display unit.

4. A hand held phone for use in a radio system, wherein the hand held phone is connected with a base station over radio channels, and further connected with a data terminal device having a predetermined communication control function required for performing a mobile data communication, the hand held phone transmits forward data from the data terminal device to the base station over a first one of the radio channels and receives reverse data from the base station over a second one of the radio channels and transfers the received reverse data to the data terminal device, comprising:

receiving means for receiving status information of the data terminal device from the data terminal device while a mode in which the data terminal device leads connection control between the hand held phone and the base station is set; and

status display means for displaying the transferred status.

5. A communication apparatus comprising:

a phone configured to be connected to a base station via a radio channel; and

a data terminal which provides the phone with data to be transmitted from the phone via a transmission signal and which is provided with data from the phone received via a reception signal,

wherein the communication apparatus is operated in one of a first mode in which the phone controls a radio communication between the phone and the base station and a second mode in which the data terminal controls the radio communication,

wherein the data terminal comprises a transmitter configured to transmit status information of the data terminal to the phone when the communication apparatus is operated in the second mode, and

wherein the phone comprises a display configured to display the status information transmitted from the data terminal.

6. A data terminal configured to be connected to a phone which transmits data to a base station via a radio channel, receives data from the base station via the radio channel and transmits the received data from the base station to the data terminal, the data terminal comprising:

a status information transmitting unit configured to transmit status information of the data terminal to the phone to cause said phone to display the transmitted status information while a communication mode in which said data terminal controls a radio communication between the phone and the base station is set.
