[Problems to be Solved by the Invention] By the way, among the game programs that can be executed on such a game device, in addition to those that can be operated (executed) by one person, there are also those that can be operated (executed) by multiple people at the same time.
There is a so-called battle-type game program in which players operate the game alternately or alternately to play against each other. When running this competitive game program, the operation keys for multiple players are arranged in advance on one game device, and in addition to the one that allows a single game device to play a competitive game, In some cases, two game devices are connected by a signal line, and a competitive game is executed between the connected game devices. In the case of a small, portable game device, it is common to connect a plurality of game devices in this way.

[0004] However, when playing a competitive game on a game device in which operation keys for multiple people are arranged on one game device, or on multiple game devices connected by signal lines, each It was difficult to conduct a battle with players separated from each other (even when connecting multiple devices with a signal line, it is not practical to make the signal line too long). Furthermore, when connecting multiple devices using signal lines, there is a high possibility that the signal lines will be damaged, resulting in low reliability.

[0005] An object of the present invention is to make it possible to easily execute a computer program such as a competitive game using a wireless communication device.

[0006]

[Means for Solving the Problems] The present invention provides a digital cordless telephone that includes a base unit and a plurality of slave units, and performs phone calls by transmitting and receiving digitized data between the slave units or between the base unit and the slave units. In the device, as shown in FIG. A display section 9 is provided to display the results of execution of the program stored in the controller, and the operation information of the operation keys 8 is transmitted as digitized data to other child devices or the parent device. .

[0007]

[Operation] By doing this, operation commands for executing various programs such as game programs are transmitted by wireless communication using a digital cordless telephone device, and for example, by using multiple handsets, It will be possible to run computer programs such as competitive games between machines.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the digital cordless telephone device of the present invention will be described below with reference to the accompanying drawings.

In this example, it is applied to a TDMA/TDD type digital cordless telephone device.
In an A/TDD type digital cordless telephone device, communication between a base unit and a handset or between each handset is performed as shown in FIG. That is, one frame is composed of a plurality of, for example, four, transmission slots T1 to T4 and the same number of reception slots R1 to R4, and slots T1 and R1
, T2 and R2, T3 and R3, and T4 and R4 are used in pairs to perform transmission and reception. In this case, in the case of a digital cordless telephone device, the signals transmitted and received are digital data, so it is easy to compress and expand the voice, and the time division multiplexing shown in FIG. 3 can be easily realized.

[0010] This TDMA/TDD transmission/reception system is characterized in that transmission and reception are performed temporally separated in the transmission slot and reception slot, so that the transmission frequency and the reception frequency can be the same frequency. This allows high efficiency in the use of each transmission channel, allowing multiple sets of cordless telephones to use the same frequency, and allowing many cordless telephones to make calls at the same time.

For example, as shown in FIG. 4, one base unit BS connected to a telephone line L has a plurality of slave units MS1,
You can make calls on both MS2s at the same time. That is, for example, using slots T1 and R1, the base unit BS and the slave unit MS1
At the same time, communication a can be performed between the base unit BS and the slave unit MS2 using slots T2 and R2.

Next, FIG. 1 shows a handset constituting the digital cordless telephone device of this example. In the figure, 1 is an antenna, and 2
is a wireless transmitter/receiver section, 3 is a modulation/demodulation section, and 4 is a TDMA/TDD
A control section 5 is a voice encoding/decoding section, 6 is a microphone device as a receiver, and 7 is a speaker as a receiver, and the operation of each of these circuits is controlled by a system controller 20. That is, a signal in a predetermined frequency band received by the wireless transmitter/receiver 2 via the antenna 1 is digitally demodulated by the modulator/demodulator 3, and the signal of the required reception slot in the demodulated signal is sent to the TDMA/TDD controller 4. Extract. and,
The extracted signal is converted into an analog audio signal by the audio encoding/decoding unit 5, and the converted analog audio signal is output from the speaker 7. Further, the voice picked up by the microphone device 6 is converted into a digital voice signal by the voice encoding/decoding unit 5, and the converted digital voice signal is converted into a TDMA signal.
/TDD control unit 4 sets it as a signal of a predetermined transmission slot. Then, the signal of this transmission slot is digitally modulated by the modulation/demodulation section 3, the modulated signal is made into a signal of a predetermined frequency band by the radio transceiver section 2, and the signal of this frequency band is transmitted from the antenna 1.

The system controller 20 also includes a key input section 8 for inputting dial numbers and operating games to be described later, and a liquid crystal display section 9 for displaying dial numbers and game progress status in characters and graphics. , and a changeover switch 10 for switching between calling and playing the game are connected.

Here, the configuration of the system controller 20 is shown in FIG. 2. The system controller 20 includes a central control unit (CPU) 21 having a microcomputer configuration, and a T.
A serial interface 22 for sending control commands to the DMA/TDD control unit 4, a communication control ROM 23 that stores communication control data, a game program ROM 24 that stores a game program, and is used during data processing. Work RAM 25 and an interface 2 for sending control commands to the wireless transmitter/receiver 2 and modulator/demodulator 3
6 is provided. In this case, the CPU 21 and each circuit 22
26 are connected by a bus line 27, and the game program ROM 24 is made into a memory card so that it can be replaced. Further, a key input section 8, a liquid crystal display section 9, and a changeover switch 10 are directly connected to the CPU 21 via this bus line 27.

When making a call from this handset, first set the changeover switch 10 to the calling side, and then select the other party (other handset, parent) by operating a predetermined key on the key input section 8. (outside line telephone). When the command from this key operation reaches the CPU 21, the CPU 21
performs an operation of calling the other party according to a program stored in the communication control ROM 23. At this time, a control channel different from the communication channel for transmitting and receiving audio data is used to communicate with the base unit. Also, at this time, the dial number of the other party (in the case of an outside line call) and the extension number (in the case of a call between handsets) are displayed on the liquid crystal display section 9.

[0016] When the other party is called, a predetermined slot in the communication channel designated by the control channel is used to transmit and receive voice, and a voice conversation is performed. Transmission and reception of voice data using the communication channel at this time is performed in the slot having the configuration shown in FIG. 5A. That is, each transmission slot and each reception slot shown in FIG.
As shown in A, a voice signal consisting of a preamble, a sync word, a control bit, voice data, and a correction code (CRC) is digitized as voice data and is transmitted to make a call. .

In this example, a game program can be executed using the handset of this digital cordless telephone device. That is, when executing a game program stored in the game program ROM 24 of the system controller 20, the changeover switch 10 is switched to the game side, and the game program is started by operating a predetermined key of the key input section 8. Instruct. By doing this, the CPU 21 becomes the RO for the game program.
The game program stored in M24 is read out, and the game content according to this program is displayed on the liquid crystal display section 9 under the control of the CPU 21. Thereafter, by sequentially operating the game execution keys in the key input unit 8 as the game progresses, the CPU 21 sequentially advances the processing of the game program, and the corresponding display is displayed on the liquid crystal display unit 9.

The game program is executed in this manner, but if the game program stored in the game program ROM 24 is a competitive game, it is possible to use two slave machines to compete. There is. That is, when playing a competitive game, the player first specifies the opponent (the extension number of the opponent's slave device) by operating the key input unit 8. When this designation is made, the CPU 21 uses the control channel to wirelessly call the other party's handset, and when the other party answers, the key input section 8 related to the game operation of each handset is thereafter operated. When this happens, information regarding this operation is wirelessly transmitted to the other party's handset using the communication channel. That is, FIG. 5B is a diagram showing the configuration of one slot of the signal transmitted using the communication channel at this time. Keystroke information is transmitted instead. Further, the correction code of this slot is also used as the correction code of the key input information. This key input information is supplied from the CPU 21 of the system controller 20 to the audio processing unit 5, and from this audio processing unit 5, TDM data is sent instead of audio data.
The signal is supplied to the A/TDD control unit 4, and transmitted with the slot configuration shown in FIG. 5B. Also, on the receiving side handset,
The key operation information supplied to the voice processing section 5 is supplied to the system controller 20, and the CPU 21 determines the key operated by the other party.

Note that the transmission of the slot including this key input information is performed by inter-mobile communication (communication c in FIG. 4) that is directly transmitted from one slave unit to the other slave unit.

In this way, based on the key operation information of both handsets, the CPUs of both system controllers 20
21 executes the game program and displays the executed results on the liquid crystal display section 9 of each child device. Therefore, the same display based on the key operations of the two handsets is displayed on the liquid crystal display section 9 of each handset, and the person operating each handset can display the same display on the liquid crystal display 9 of both handsets. You can judge the match status of the game from the display.

[0021] By being able to execute a competitive game program on two child machines in this way, two people who are located at separate locations can play a competitive game. In this case, by using a handset that constitutes a digital cordless telephone device, the game operation status is transmitted to the other party using the communication function between handsets that this handset has, and the signal line connects both handsets. You can easily play competitive games without the need for direct connection, etc., and the functions of the handset are effectively utilized, so the configuration of the handset does not become complicated.

[0022] In the above-mentioned embodiment, key operation information when executing a competitive game program is transmitted to the opponent's slave machine. When executing
Key operation information may be transmitted to the other party. In addition, in the above embodiment, key operation information is transmitted between two handsets, but by transmitting key operation information between two or more handsets, more people can play against each other. It may also be possible to play a type game. Furthermore, in the above embodiment, key operation information is transmitted through communication between handsets, which is direct communication between each handset, but it is transmitted from one handset to the other handset via the base device. It is also possible to carry out the communication (using transmissions a and b in FIG. 4).

[0023]

According to the present invention, an operation command for executing various programs such as a game program is transmitted by wireless communication using a digital cordless telephone device, and a plurality of computer programs such as a competitive game can be executed. You can easily run it from a remote location using a slave device.
