DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone apparatus comprising a base station connected to a telephone line and one or more mobile stations wirelessly connected to the base station for calculating and displaying a talk time. About.

[0002]

2. Description of the Related Art There is generally known a telephone device which calculates a telephone call time and displays it on a display means.
When a telephone call is made not only at the base station (parent device) but also at the mobile station (child device) as in a cordless telephone device, there is a case where it is desired to calculate and display the above-mentioned call time at the mobile station.

Therefore, in a conventional cordless telephone device,
The mobile station is configured to calculate and display the call time.

[0004]

However, in the case where a plurality of mobile stations are used, when a call is transferred from one mobile station to another mobile station, the transfer destination mobile station uses the transfer source mobile station. Is not configured to be notified of the call duration. Therefore, the transfer destination mobile station only measures the talk time after the transfer. Therefore, the user of the transfer destination mobile station does not know the total call time of this call,
In particular, in the case of a long-distance call, it is not preferable because it is not possible to know how much the telephone charge is, and it is not possible to judge how long the call time may be continued.

According to the present invention, in order to solve the above-mentioned problems, even when there are a plurality of mobile stations, the total call time when the data is transferred between the mobile stations is calculated by the base station, and this is calculated by the base station. It is an object of the present invention to provide an excellent cordless telephone device that can be displayed on a station.

[0006]

In order to achieve this object, a cordless telephone device according to the present invention comprises: a base station, a call time measuring means for starting measurement when a telephone line is formed, and a base station. Notification means for notifying the transfer destination mobile station of the call time measured by the call time measurement means when transferring a call from the mobile station or one mobile station to the other mobile station; And display means for displaying the call time notified from the base station.

[0007]

Therefore, according to the present invention, since the call duration of the transfer source is automatically notified to the transfer destination mobile station, the person who continues the call at the transfer destination mobile station includes the call duration of the transfer source. The entire call time can be easily confirmed on the display means provided in the transfer destination mobile station.

Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG. (1) Mobile station 30
When the mobile station 30 enters the talking state, the mobile station 30 drives the timer 40 to measure the talking time, and displays the talking time by the talking time display means 39 (step 1). At this time, mobile station 5
0 is waiting (step 2). The base station 10 recognizes that a call is being made with the mobile station 30, and measures the call time with the timer 18 (step 3). (2) When the mobile station 30 is activated for suspension When the suspension is activated in the mobile station 30 (step 4).
YES), the hold start data generating means 35 generates hold start data notifying that the hold has been started. The hold activation data is transmitted by the control means 41 to the base station 10 through the RF transmission circuit 32 and the antenna 31 (step 5).

The above-mentioned suspension start data is received by the RF receiving circuit 13 via the antenna 11 of the base station 10 (step 6). At this time, the base station 10 activates the suspension by the suspension activation means 15 (step 7), puts the base station 10 in the suspension state (step 8), and transmits the system suspension data from the RF transmission circuit 12 to the antenna 11 by the control means 20. To the mobile stations 30 and 50 respectively. When the system hold data passes through the antenna 31 and is received by the RF receiving circuit 33, the control means 41 activates the hold by operating the hold activating means 34 (step 9). As a result, the mobile station 30 is put on hold (step 10).

The system hold data is transmitted to the antenna 51.
When the signal is received by the RF receiving circuit 53 through the
1 activates the hold by operating the hold activation means 54 (step 11). As a result, the mobile station 50 is put on hold (step 12). The mobile station 30, 5
Even during the operation of 0, the base station 10 continuously measures the talk time by the timer 18. (3) Release of Hold of Mobile Station 50 In the mobile station 50, when the hold release operation is performed by the hold release means 57 (YES in step 13), the hold release data generating means 56 generates hold release data.
The control means 61 transmits the hold release data from the RF transmission circuit 52 to the base station 10 via the antenna 51 (step 14).

When the hold release data is received by the RF receiving circuit 13 via the antenna 11 (step 15),
The control means 20 decodes the hold release data by the hold release data decoding means 16, and the base station 10 performs the hold release operation by the hold release means 17. At this time, the control means 20
Transmits the hold release data from the RF transmission circuit 12 to the antenna 11
To the mobile stations 30 and 50 respectively (step 16).

When the hold release data passes through the antenna 31,
When received by the F receiving circuit 33, the control means 41 operates the hold release means 37, whereby the mobile station 30 releases the hold (step 17) and enters a standby state (step 1).
8). Also, the hold release data passes through the antenna 51, and R
When the signal is received by the F receiving circuit 53, the control means 61 operates the hold release means 57 to release the hold of the mobile station 50 (step 19), and the mobile station 50 enters the talking state. (4) At the time of a call from the mobile station 50 The base station 10 transmits the hold release data to the mobile stations 30, 5
0, and at the same time, call time display data for notifying the current total call time is generated by the call time data generating means 19, and transmitted to the mobile station 50 through the above-described wireless path (step 20). . After sending,
The base station 10 detects the call state of the mobile station 50 by the control means 20, and operates the timer 18 (step 21).
The total call time display data transmitted in step 20 is received by the mobile station 50 through the above-described wireless path (step 22). At the mobile station 50, the hold is released in step 19, and at the same time, the talk time data decoding means 58 decodes the talk time display data. Further, the mobile station 50
When the communication state is established, the timer 60 continuously measures the communication time display data. The control means 61 displays the measured result on the call time display means 59 in real time (step 23).

As described above, according to the present embodiment, when a call is transferred from the mobile station 30 to the mobile station 50, the talk time of the mobile station 30 measured by the timer 18 of the base station 10 is changed to the talk time display. The data is wirelessly transmitted to the mobile station 50 as data and displayed on the call time display means of the mobile station 50, so that the user of the mobile station 50 can check the total call time.

Further, in this embodiment, (4) only one radio transmission of the call time display data from the base station 10 to the mobile station 50 at the time of the call of the mobile station 50 is required. Can be prevented.

In this embodiment, the two mobile stations 30, 5
The total call time is measured and displayed for the hold transfer between 0, but it goes without saying that the total call time can be measured and displayed for the hold transfer between three or more mobile stations.

[0023]

According to the present invention, as is apparent from the above embodiment, since the calculation of the total talk time is managed by the base station, the transfer destination can be transferred from one mobile station to the other mobile station. You can check the total talk time during transfer at the mobile station.

This has the effect that the user at the transfer destination can manage the call charges.
