Description

[Detailed description of the invention] The present invention relates to a device that connects a base station connected to a subscriber line and a wireless telephone via a wireless line to make a call, and in particular improves the speed dial function, the configuration, and The present invention relates to a wireless telephone device with simplified control.

Conventionally, in subscriber telephone systems, so-called abbreviated dialing has been implemented, in which a dial number is stored in a station device using a push-button dial telephone, and a specific party telephone can be called by dialing a small number of digits. However, with speed dialing using this station equipment, for example, 20
Because you can only register the set number of the other party's phone number,
Some subscribers felt that the number of registrations was not sufficient and expressed a desire for an increase in the number of registrations.

Therefore, in wireless telephone systems that have become popular in recent years, an attempt has been proposed to increase the number of registrations by providing a base station with a dial number storage function for speed dialing. However, in conventional wireless telephone systems, the wireless telephone generates and transmits a push-button signal (PB signal) using tones according to each dialed number, and the base station demodulates the PB signal and transmits it to the subscriber line. ing. Therefore, in order to memorize the dialed number at the base station,
Since the tones of the dial signal, which has a total of seven waves, must be selected using narrow-band filters and converted into a form suitable for storage, the configuration and control become extremely complicated and the device becomes expensive.
It was not suitable for practical use.

On the other hand, as another method that does not cause the above-mentioned drawbacks, it is possible to provide a dial number storage function within the wireless telephone. However, with this type of system, a backup power supply must be provided exclusively for the memory circuit in order to prevent stored information from being erased as the wireless telephone's battery runs out, making it difficult to make the telephone smaller and lighter. This was not desirable as it had drawbacks that were a major hindrance.

The present invention was developed in view of the above circumstances, and its purpose is to increase the number of speed dial registrations by providing a base station with a dial number storage function for speed dialing, and to easily increase the number of speed dial registrations. The object of the present invention is to provide a highly functional and inexpensive wireless telephone device that can be realized with a simple configuration and control.

In this invention, the base station is provided with a storage unit for dialed numbers, and when the dialed number is sent to the base station, it is converted into a digital code signal by a radio telephone and sent out, and this digital code signal is reproduced at the base station. The above object is achieved by storing the information as it is in the storage unit.

An embodiment of the present invention will be explained below with reference to the drawings. The figure is a block diagram showing the configuration of the parts related to the present invention of the wireless telephone device in the same embodiment.
In the figure, 1 indicates a wireless telephone, and 2 indicates a base station connected to the subscriber line 3. The radio telephone 1 and the base station 2 are connected to each other via a radio line 4.

The wireless telephone 1 has a push button dial 11
When the button is operated, the dial conversion circuit 12 generates, for example, a 4-bit digital code signal according to the position of the operated button, and the signal control circuit 1 generates a 4-bit digital code signal.
After the control tone signal is modulated by the digital code signal at step 3, a carrier wave is modulated by the control tone signal at the transmitting circuit 14 and sent to the radio line 4. Here, the push button dial 11 is composed of a dial push button consisting of numeric buttons from 0 to 9 and function buttons used for speed dialing, etc., and a speed dial push button newly installed for the speed dial of the present invention. has been done. This speed dial push button consists of only one push button, push button dial 11.
generates a speed dial registration signal when the speed dial push button is operated when the radio telephone is turned on, and generates a speed dial output signal when it is operated when the speed dial is turned off.

On the other hand, the base station 2 first receives radio waves from the wireless telephone 1 in the receiving circuit 21, demodulates them to obtain a control tone signal, and transmits this tone signal to the signal control circuit 21.
demodulates and reproduces the digital code signal.
Then, the digital code signal is sent to the switch circuit 2.
3 to the dial signal generation circuit 24, and also to the abbreviated dial registration signal detection circuit 25 and the abbreviated dial output signal detection circuit 26, respectively. Speed dial registration signal detection circuit 2
5 detects a speed dial registration signal by comparing the digital code signal with a preset code. On the other hand, the speed dial output signal detection circuit 26 detects the speed dial output signal by comparing the digital code signal with a preset code. Further, the switch circuit 23 is
Normally, it is connected to the dial signal generation circuit 24 side, and when a speed dial registration signal or speed dial output signal is detected by the speed dial registration signal detection circuit 25 or speed dial output signal detection circuit 26, at that point It is designed to switch to the memory circuit 27 side. The storage circuit 27 enters a writing state when the abbreviated dial registration signal is detected, and then stores the dialed number reproduced by the signal control circuit 22 in association with the abbreviated number reproduced at the same time. For example, an abbreviated number (maximum 100 sets consisting of 00 to 99) is specified as an address in RAM, and a dial number is stored in this address. Further, the memory circuit 27 enters a read state when the abbreviated dial output signal is detected, reads out a dial number according to the abbreviated number reproduced by the signal control circuit 22, and stores this dial number in the state of the digital code signal. The signal is supplied to the dial signal generation circuit 24. In this case as well, the dialed number is read by using the abbreviated number as it is as the RAM read address. Note that the switch circuit 23 switches the dial signal generation circuit 2 from the storage circuit 27 side when each operation of writing or reading the dial number in the storage circuit 27 is completed.
Switch to the 4th side. The dial signal generation circuit 24 is
It converts dial numbers and control signals made of digital code signals outputted from the signal control circuit 22 or storage circuit 27 into PB signals and control tone signals, and sends them to the subscriber line 3.

Next, the operation of the above configuration will be explained. First, when making a normal call from wireless telephone 1,
When a dial push button on the pushbutton dial 11 is operated, a digital code signal is generated from the dial conversion circuit 12 corresponding to the operated button, a control tone signal is modulated by this digital code signal, and the control tone signal is A carrier wave modulated with the signal is sent to the base station 2. On the other hand, the base station demodulates the carrier wave and reproduces the digital code signal. At this time, since the switch circuit 23 is normally connected to the dial signal generation circuit 24 side, the digital code signal is directly guided to the dial signal generation circuit 24,
This circuit 24 converts it into a PB signal and sends it to the subscriber line 3.
sent to. Then, the exchange calls the other party's telephone, and if the other party responds, the call becomes possible.

On the other hand, when making a call using normal speed dialing using the speed dial service of a central telephone office, the well-known operating procedures specified by this service,
That is, this can be done by specifying an abbreviated number corresponding to a pre-registered subscriber number (dial number) using numeric buttons following a function button among the dial push buttons. That is, in this case as well, the switch circuit 23 of the base station 2 is connected to the registration signal detection circuit 2.
5 and the output signal detection circuit 26 do not detect the speed dial registration signal and the speed dial output signal, so they remain connected to the dial signal generation circuit 24 side, and as a result, each call information for the speed dial described above remains unchanged. The signal is guided to the dial signal generation circuit 24, where it is converted into a control tone signal and a PB signal, and then sent to the exchange.

Next, the speed dial function provided in the base station 2 will be explained. First, to register a speed dial, in this case, the user operates a newly installed speed dial push button while in the hook-on state. Then, a digital code signal corresponding to the abbreviated dial registration signal is generated from the dial conversion circuit 12 and sent to the base station 2. This digital code signal is reproduced by a signal control circuit 22 in the base station 2 and then detected by a speed dial registration signal detection circuit 25. Then, the switch circuit 23 is switched from the dial signal generation circuit 24 side to the storage circuit 27 side, and the storage circuit 27 enters the write state. In this state, push button dial 11
When the dialing push button is operated to generate digital code signals corresponding to each number in the order of abbreviated number and dialed number, these digital code signals are sent to the base station 2 for reproduction, and are transmitted via the switch circuit 23. and is introduced into the storage circuit 27. As a result, the storage circuit 27 first specifies a write address in accordance with the digital code signal corresponding to the abbreviated number, and stores the digital code signal corresponding to the dialed number in the specified address. Then, when the storage is completed, the switch circuit 23 is switched to the dial signal generation circuit 24 side by a control signal (not shown). In this way, the dial number for speed dialing is registered in the storage circuit 27 provided in the base station 2.

The registered speed dial is used to make a call; in this case, the user presses the speed dial push button after hooking off. Then, the dial conversion circuit 12 generates a digital code signal corresponding to the abbreviated dial output information and sends it to the base station 2. This digital code signal is transmitted to the base station 2.
After being reproduced by the signal control circuit 22, the signal is detected by the speed dial output signal detection circuit 26. Then, the switch circuit 23 switches to the memory circuit 27 side, and the memory circuit 27 enters the read state. In this state, when the dial push button is operated on the radio telephone 1 to generate a digital code signal corresponding to the abbreviated number, this digital code signal is reproduced at the base station 2 and then introduced into the storage circuit 27. . As a result, the storage circuit 27 specifies a readout address using the digital code signal corresponding to the abbreviated number, and reads out the digital code signal corresponding to the dial number stored at this address. This digital signal is sent to the dial signal generating circuit 24.
It is converted into a PB signal and sent to the exchange, and as a result, the called party's telephone corresponding to the dialed number is called, and if the other party answers, the call can be made.

As described above, according to this embodiment, the base station 2 is provided with the memory circuit 27, etc., and the push button dial 11 of the radio telephone 1 is newly provided with a speed dial button, so that the radio telephone device has the speed dial registration function. As a result, the number of registered speed dials can be increased, making it possible to fully meet the demand for an increase in the number of registered speed dials. Moreover, in this embodiment, when sending a dial number from the radio telephone 1 to the base station 2, the radio telephone 1 converts it into a digital code signal and sends it, reproduces it at the base station 2, and directly sends it to the storage circuit 27. Since the memory signal and the calculation signal in each of the detection circuits 25 and 26 are used, a large number of filters, backup power supplies, etc. are not required, and there is an advantage that the configuration and control can be significantly simplified. Furthermore, according to this embodiment, the speed dial registration signal and the speed dial output signal are associated with the hook operation so that they can be generated by only one push button, so the number of newly installed push buttons is limited to the minimum number. It is possible to realize a more compact device.

Note that the present invention is not limited to the above embodiments. For example, a speed dial registration signal is generated when a speed dial push button is operated within a certain period of time after a call is terminated, while a speed dial registration signal is generated when a speed dial push button is operated while a call is being made. The speed dial output signal may be generated when the speed dial output signal is reached. In addition to the PB signal, the dial signal sent to the subscriber line may be converted into a dial impulse and sent. Further, the signal sent to the base station 2 may be one in which a carrier wave is directly modulated with a digital code signal, and the digital code signal sent out and the digital signal stored in the storage circuit may not have the same code form. ,
Other configurations of the memory circuit and the switch circuit can be modified in various ways without departing from the gist of the present invention.

As detailed above, the base station is provided with a storage unit for dialed numbers, and when the dialed number is sent to the base station, it is converted into a digital code signal by a wireless telephone and sent out, and the base station converts the dialed number into a digital code signal. The present invention, which is played back and stored as is in the storage unit, can increase the number of registered speed dials, and can be realized with a simple configuration and control, making it possible to create a highly functional and inexpensive wireless telephone device. can be provided.
