Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low power cordless telephone device and a telephone device capable of communicating without interruption even if other signals are mixed during the telephone conversation. The present invention relates to a data transmission method.

[0002]

2. Description of the Related Art A cordless telephone is used by freely carrying it within a certain range by replacing a part of home wiring of a subscriber line of a general subscriber telephone network with a wireless line. By connecting a cordless telephone connecting device to the rosette of the subscriber line, a wireless call is enabled between the connecting device and the cordless telephone. here,
The connection device is called a master unit and the cordless telephone is called a slave unit. At first, the service using one fixed frequency wireless channel was performed, but 400/25 is used as a method that is strong against interference.
Services for using 46 radio channels in the 0 MHz band by the multi-channel access method have been implemented for eight years. In a conventional cordless phone, the
For data transmission, the conversation was stopped, the button was pressed, the call path was temporarily cut off, and then the data was transmitted from the main unit. That is, data cannot be transmitted from the main device unless the conversation is stopped and the call path is temporarily cut off.

[0003]

As described above, in the conventional cordless telephone system, the information held by the master unit is transferred to the slave unit and the slave unit after the call mode is entered. In order to send the information held by the device to the base unit, it is necessary to put a signal on the up and down radio waves used for the call, and the frequency for the call is used. That is, when such a signal is transmitted during a call, a signal sound is mixed in the call. Further, in order to prevent the mixing of the signal sound, a method of disconnecting the communication path only during transmission and reception of the signal can be considered. However, a call is interrupted every time a signal is transmitted, so that a smooth call cannot be guaranteed. On the other hand, there is also a method of using another radio wave for data communication. Certainly, with this method, the frequency is
It does not affect the call because it is used one extra, but since one set of cordless telephone equipment uses two sets of radio waves, considering that the radio band is finite. , Extremely inefficient. An object of the present invention is to solve such a conventional problem and to make a cordless telephone device capable of transmitting data between a slave unit and a master unit without interrupting the conversation even during a call, and a call. It is to provide a medium data transmission method.

However, on the premise that the caller does not receive voice, a data storage device for temporarily storing information to be transmitted to the parent device or the child device using the receiving channel is provided. Features That. Further, according to the in-call data transmission method of the present invention, (b) the voices of the caller of the handset and the other party of the call are detected during the call, and the receiving channel is used while the voice is detected. Then, the external line usage status data on the master unit side is transmitted from the master unit side to the slave unit side, the external line usage status is displayed on the display unit on the slave unit side, and the slave unit side data is also called by the other party. The feature is that the person sends it to the base unit while talking. Also,
(C) The base unit detects the voices of the caller and the other party of the handset during a call, and while detecting the voice, uses the receiving channel to connect to the external line of the base unit. The data of the incoming call status is transmitted from the master unit to the slave unit, the incoming call status of other external line is displayed on the display unit on the slave unit side, and the other party's caller is also transmitting the data on the slave unit side. It is also characterized by sending to the base unit. In addition, (d) the base unit detects the voices of the caller of the handset and the other party during the call, and while detecting the voice, uses the receiving channel to make a call on the base unit side. The data of the charge addition status is transmitted from the master unit to the slave unit side, and the call addition status is displayed on the display unit on the slave unit side, and the partner caller also transmits the data on the slave unit side. It is also characterized in that it is sent to the base unit.

[0005]

In the present invention, it is possible to assume that the other party is receiving a call when the handset is transmitting a call. Therefore, the call channel should be used to display the call on the outside line or to display the charge on the handset. Send information from the master to the slave. In this case, the other party may also be talking at the same time while the handset is talking, so determine whether the other party is talking and only if the other party is not talking Information from the device to the child device. When transmitting information from the base unit to the handset, the call / signal switching device for transmission on the base side is automatically switched to a signal, and then the information stored in the data storage device is transferred to the handset. Send to the side. Also, on the side of the handset, when the caller is transmitting a call, data can be received by automatically transmitting a notification from the call / signal switching device for transmission to the switching device for reception. ..

Send to the handset using the communication channel (radio waves) that is assumed not to be transmitting. As for the movement of the display, if there is an outside line call every time I speak, the information of the call is sent from the main unit and the LCD on the handset displays it. First, it is determined whether or not the call is on hold (step 301), and if it is not on hold, it is determined whether or not the handset is transmitting a call (step 302). If no transmission is in progress, if there is transmission information from the child device side, it is transmitted to the parent device side (step 306). Also, the other party of the call may be transmitting. On the other hand, if the handset is transmitting, it is determined whether or not the communication partner is also transmitting (step 303). If the other party is not transmitting, it is determined whether the call charge has been added (step 304). If it has been added, the communication path is switched from the voice to the signal from the master unit to the slave unit, and the signal relating to the call charge is transmitted (step 305). When there are many signals to be transmitted, the transmission time is divided into a plurality of parts and divided into a plurality of parts for transmission. When using this in the structure of the present embodiment, if the user enters the call state and speaks, information will be sent. Therefore, there is no particular usage on the handset side that is different from usual.
