DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is a block diagram showing a radio telephone apparatus 100 in the
first embodiment of the invention.
The radio telephone apparatus 100 comprises: an antenna 101 for
transmitting and receiving a radio wave to/from a fixed equipment 10; a
transmission and reception unit 102 for modulating a voice and data to be
transmitted to the fixed equipment 10 and for demodulating the voice and
data from the fixed equipment 10; a voice processing unit 103 for
performing an amplification or the like of the voice to be transmitted and
received; a voice switching unit 104 for switching a voice signal to a
transmitter 105 and a receiver 106 or to an external handset 20 which is
connected to an external handset connection unit 107; a modem 108 for
sending a data signal from the fixed equipment 10 to a control unit 109
and for transmitting the data signal from the control unit 109 to the
fixed equipment 10; the control unit 109 for controlling the transmission
and reception unit 102 and modem 108, for accepting an input from a key
pad 114, and for controlling the voice switching unit 104 by a
notification from an external handset connection detection unit 110; the
external handset connection detection unit 110 for detecting that the
external handset 20 has been connected to the external handset connection
unit 107, thereby notifying to the control unit 109; a charge detection
unit 111 for detecting that a charge table 910 has been connected to the
charge table connection unit 112, thereby notifying to the control unit
109; a charge battery 113; the key pad 114 for inputting various data such
as a dial number and the like; a display unit 115 for displaying various
information such as a dial number and the like; and a state notification
unit 901 for notifying a use state to the charge table 910.
Reference numeral 910 denotes the charge table having a charge current
control unit 911 for controlling a charge current and a rectification unit
912 for converting an alternating current to a direct current.
The operation of the embodiment will now be described with reference to a
flowchart for each process.
FIG. 2 is a flowchart showing a speech communication end process of the
control unit 109 in the embodiment.
First, in a speech communication state (S201), when it is detected that the
external handset 20 has been connected (S202), the voice switching unit
104 is controlled, thereby connecting a voice signal to the external
handset 20 side (S203). In this case, only when a speech communication end
key in the key pad 114 is depressed (S204), a speech communication end
process is executed (S208), thereby avoiding that information regarding
whether the apparatus has been put on the charge table 910 or not is
concerned with the speech communication end process. After completion of
the speech communication end process, the control mode is set into a
stand-by mode.
When it is detected that the external handset 20 is not connected (S202),
the voice signal is connected to the built-in transmitter 105 and receiver
106 (S205). In this case, in step S208, the speech communication end
process is executed in both of a case where the handset has been put on
the charge table 910 (S206) and a case where the speech communication end
key in the key pad 114 has been depressed (S207).
When the radio telephone apparatus 100 is put on the charge table 910 in a
communicating state, in case of continuing the communication even when the
radio telephone apparatus 100 is put on the charge table 910, the
communication is continued and the state notification unit 901 notifies a
state in speech communication to the charge current control unit 911.
In response to such a notification, the charge current control unit 911
supplies a current larger than a current in a stand-by state of the radio
telephone apparatus 100. When the radio telephone apparatus 100 finishes
the communication, the state notification unit 901 notifies the charge
current control unit 911 of the fact that no communication is being
executed.
In response to such a notification, the charge current control unit 911
supplies the charge current for the stand-by mode. The embodiment has been
described here as an example with respect to two modes of the
communication mode and stand-by mode and two charge currents corresponding
to them. The invention can be also applied to a case of an arbitrary
number of communication modes and charge currents.
FIG. 3 is a flowchart showing a call generation process of the control unit
109 in the embodiment.
First, in the stand-by mode (S301), when it is detected that the external
handset 20 has been connected (S302), the voice signal is connected to the
external handset 20 side (S303). In this case, when the handset is put on
the charge table 910 (S304), by releasing the handset from the charge
table 910 (S305) or by depressing a call generation key (S306), a call
generating process is executed (S311). When the handset is not put on the
charge table 910, by depressing the call generation key (S306), the call
generating process is executed.
On the other hand, when it is detected that the external handset 20 is not
connected (S302), the voice signal is connected to the built-in
transmitter 105 and receiver 106 (S307). In this case, a check is made to
see if the handset has been put on the charge table 910 or not (S308).
When it is put on the charge table, by detecting that the handset has been
released from the charge table 910 (S309), the call generating process is
performed (S311). When the handset is not put on the charge table 910, by
depressing the call generation key in the key pad 114 (S310), the call
generating process is executed (S311).
FIG. 4 is a flowchart showing a call reception responding process in the
control unit 109 of the embodiment.
First, when there is a reception notification (S402) in the stand-by mode
(S401), a check is made to see if the external handset 20 has been
connected or not (S403). When the handset is connected, the voice signal
is connected to the external handset 20 side (S404).
In this case, when the handset is put on the charge table 910 (S405), by
releasing the handset from the charge table 910 (S406) or by depressing a
response key (S407), the responding process is performed (S412). When the
handset is not put on the charge table 910, by depressing the response key
(S407), the call generating process is executed (S412).
In the case where the external handset 20 is not connected, the voice
signal is connected to the built-in transmitter 105 and receiver 106
(S408). A check is made to see if the handset has been put on the charge
table 910 or not (S409). If YES, by detecting that the handset has been
released from the charge table 910 (S410), the responding process is
performed (S412). When the handset is not put on the charge table 910, by
depressing the response key in the key pad (S411), the responding process
is executed (S412).
The second embodiment of the invention will now be described.
FIG. 5 is a block diagram showing a radio telephone apparatus of the second
embodiment.
A radio telephone apparatus 500 comprises: a data terminal interface 504
for enclosing a data terminal equipment 25; a connection unit 507 for
connecting the data terminal equipment 25; and a data terminal connection
notification unit 510 for detecting that the data terminal equipment 25
has been connected and for notifying to a control unit 509.
Reference numerals 501 to 503, 505, 506, 508, 509, 511 to 515, and 951
shown in FIG. 5 denote component elements having the same names and
substantially the same functions as those of the component elements 101 to
103, 105, 106, 108, 109, 111 to 115, and 901 shown in FIG. 1,
respectively. Therefore, their descriptions are omitted here.
In the second embodiment, data from the data terminal equipment 25 is sent
to control unit 509 through the data terminal interface 504 and is also
transmitted to the fixed equipment through a voice processing unit 503 and
a transmission and reception unit 502.
Data to the data terminal equipment 25 passes through the transmission and
reception unit 502 and voice processing unit 503 and is processed by the
data terminal interface 504. After that, the processed data is sent to the
data terminal equipment 25.
The other operations are similar to those in the case where the external
handset 20 in the above first embodiment is replaced by the data terminal
equipment 25. In each of the flowcharts for the speech communication end,
call generation, and reception response shown in FIGS. 2 to 4, by
replacing the voice signal to the external handset 20 by the data signal
and by replacing the external handset 20 by the data terminal equipment
25, the operation in the second embodiment is obtained.
The third embodiment of the invention will now be described.
In the third embodiment, whether a speech communication disconnecting
operation in each of the foregoing embodiments is executed or not or
whether the call generating operation and a reception responding operation
are enabled to be performed or not can be preset by a predetermined
operation of the radio telephone apparatus.
FIG. 6 is a flowchart showing such a presetting process. FIGS. 7A to 7C are
explanatory diagrams showing a transition of the display upon setting. A
construction of the third embodiment is substantially common to that of
FIG. 1.
First, when a setting key in the key pad 114 is depressed (S601), a display
to select a disconnection mode appears on the display unit 115 (FIG. 7A).
By inputting "0" here (S606), a mode such that when it is detected that
the external handset 20 has been connected as mentioned above, even if the
handset is put on the charge table 910 in a speech communicating state,
the speech communication disconnecting operation is not executed is set
(S607).
By inputting "1" (S606), a mode such that even when it is detected that the
external handset 20 has been connected, the speech communication
disconnecting operation is executed so long as the handset is put on the
charge table 910 in the speech communicating state is executed (S608).
By further depressing the setting key (S602), a display to select the call
generation mode appears on the display unit 115 (FIG. 7B). Now, by
inputting "0" (S609), a mode such that when it is detected that the
external handset 20 has been connected, the call generating operation is
executed even if the handset has been put on the charge table 910 is set
(S610).
By inputting "1" (S609), a mode such that even when it is detected that the
external handset 20 has been connected, the call generating operation
cannot be executed so long as the handset is put on the charge table 910
is set (S611).
By further depressing the setting key (S603), a display to select the
response mode appears on the display unit 115 (FIG. 7B). By inputting "0"
here (S612), a mode such that when it is detected that the external
handset 20 has been connected, the responding operation can be executed so
long as the handset is put on the charge table 910 is set (S613).
By inputting "1" (S612), a mode such that even when it is detected that the
external handset 20 has been connected, the responding operation cannot be
performed so long as the handset is put on the charge table 910 is set
(S614).
By further depressing the setting key (S604), the processing routine is
released from the setting mode (S605).
The fourth embodiment of the invention will now be described.
FIG. 8 is a block diagram showing a system construction according to the
fourth embodiment.
In the diagram, a main apparatus 801 encloses a plurality of external lines
and a plurality of extensions and has an exchanging function and executes
a whole control of the system. A line 802 is an extension of a PBX
(private exchange), an ordinary subscriber's line, or the like.
An extension 803 is a line to connect radio telephone apparatuses 809 and
810 and a telephone 808 exclusively used for extension. An office line
interface 804 encloses the line 802 such as PBX extension, ordinary
subscriber's line, or the like. A telephone interface 805 exclusively used
for extension encloses the telephone 808 exclusively used for extension.
A control unit 807 controls a speech communication path 806, the office
line interface 804, and the extension interface 805 and also controls the
call generation and reception and response of the radio telephone
apparatus to which the external handset is connected.
The radio telephone apparatus comprises: the fixed equipment 809 connected
to the main apparatus 801; and the moving equipment 810 that is connected
to the fixed equipment 809 by a radio wave.
In the embodiment, the call generation and reception and response of the
radio telephone apparatus is set by the telephone 808 exclusively used for
extension and its procedure is similar to that of the flowchart shown in
FIG. 6. Information that is displayed in the telephone 808 is also similar
to that shown in FIGS. 7A to 7C.
The data set as mentioned above is stored into the control unit 807 of the
main apparatus 801 and controls the operation of the radio telephone
apparatus.
Even when the set data is transferred to the moving equipment 810 through
the fixed equipment 809 and the call generation and reception and response
is controlled in the moving equipment 810, a similar effect is obtained.
Even when data is input from a data terminal equipment that can be
connected to the main apparatus 801 in order to set the data, a similar
effect can be also derived.
In the above embodiments, when the connection is detected by the connection
detection unit 110 or 510, the voice switching unit 104 or 504 is
switched. However, the voice switching section can be also switched and
connected on the basis of an instruction of the key pad 114.
Although the present invention has been described above with respect to the
preferred embodiments, the invention is not limited to the foregoing
embodiments but many modifications and variations are possible within the
spirit and scope of the appended claims of the invention.
