Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line connection device for connecting a line of a wireless telephone which provides a service of a wireless call or a wireless call.

[0002]

2. Description of the Related Art In recent years, various mobile communication services using radio have been put into practical use. Broadly speaking, these are wireless telephones that make wireless calls with telephones connected to the telephone service network via wireless communication stations, and messages that are input from telephones also connected to the telephone service network are received from the wireless communication stations. Radio caller to display (so-called pager)
Classified as

The former radio telephone is operated as a mobile telephone, a car telephone, or a personal mobile telephone (so-called PHS) depending on the radio communication network used, and the radio telephone according to the use condition can be used. The latter radio caller is operated as a so-called pager, and is being advanced in functionality such as receiving a message that is a combination of numbers and symbols input from a touch-tone phone and displaying a fixed message or kana character.

[0004]

However, in order to use the conventional mobile communication service, the following problems have not been solved yet. Since the mobile communication service uses a wireless communication network, the number of communication channels is limited, and if the number of users in the same area exceeds the number of communication channels, no one can talk. In particular, in mobile communication services, users not only send information unilaterally but also can talk to each other, so that the user tends to take a longer time to monopolize the communication channel. There is an increased possibility that other users of the service will be unable to communicate. On the other hand, in the case of a wireless calling machine, a message consisting of a combination of simple numbers and symbols is only unilaterally wirelessly transmitted, and the amount of information that can be transmitted is extremely small, but the monopoly time of a communication channel for one user is short. The possibility of loss of communication is extremely low.

Of course, if the number of mobile communication channels is large, such a condition that the call cannot be made is less likely to occur, but there are cases where the call is busy, and there are still places where it is difficult to make a call in the mobile communication such as an underground mall. To do. Also, you cannot call when you are outside the area where you can talk or when the power is off. On the other hand, a wireless pager such as a pager is
Less than mobile communications. Therefore, in order to make contact without fail, it is necessary to carry two types of communication terminals, a wireless telephone and a wireless calling machine, which impairs portability, which is the main purpose of mobile communication services.
In addition, for wireless communication with a user carrying two or more types of communication terminals, the line connection method of each communication terminal, that is, message information including a telephone number, numbers, and symbols is stored. It was necessary and complicated.

[0006]

The present invention has been made to solve the above-mentioned problems, and the line connection device of the present invention provides a telephone service network via a wireless communication station. Radiotelephone means for making a radio call with a connected telephone, and a radio for receiving message information input from the telephone and wirelessly transmitted from the radio communication station or another radio communication station, and displaying according to the message information. A line connection device for connecting a line of a radiotelephone, which is integrally provided with a calling unit, and a call failure detecting unit for detecting that the wireless phone unit is in a state where a wireless call cannot be made, and the call disable detecting unit Message information transmitting means for transmitting desired message information to the wireless calling means when it is determined that the wireless telephone means is in a state where wireless communication cannot be performed. And summarized in that comprises a.

According to such a line connection device, when the line connection is established between the radio telephone unit and the radio telephone having the radio calling unit, the radio telephone unit having a large amount of transmitted information is selected to try the line connection. The telephone means is in a wireless call,
When it is judged by the call failure detection means that it is in a state where wireless communication is not possible, such as when leaving the area where communication is possible
The message information transmitting means transmits desired message information to the radio calling means. As a result, the user can be surely contacted even when the wireless telephone is in a state where wireless communication cannot be performed. In other words, this line connection device has a radio telephone means and a radio calling means, so that the line connection to the radio telephone means at the time of line connection with the radio telephone having excellent portability that achieves both the amount of transmitted information and the constant communication. When it is impossible, the line connection with the radio calling means is automatically performed, so that the user only has to learn a single line connection operation.

[0008]

Other Embodiments of the Invention As another embodiment of the present invention, firstly,
Wireless telephone means for making a wireless call with a telephone connected to a telephone service network via a wireless communication station, and receiving message information input from the telephone and wirelessly transmitted from the wireless communication station or another wireless communication station. It is possible to consider a configuration of a wireless telephone in which a wireless calling unit that performs display according to the message information is integrated in the same housing.

[0009] In such a wireless telephone, a wireless telephone means for making a wireless call with a large amount of transmitted information to a telephone connected to a telephone service network via a wireless communication station, and receiving and displaying message information input from the telephone. The wireless call means capable of always communicating is built in the same housing, and the integrated wireless phone means and wireless call means satisfy the portability and space saving, and make a wireless call. Means and wireless calling means are available. As a result, by simply carrying this wireless telephone, it is possible to enjoy an ideal mobile communication service that achieves both the reliability of constant communication and the large amount of transmitted information.
If the wireless telephone and the wireless calling unit are operated in a time-sharing manner, it is possible to reduce the overall power consumption as compared with the case where both are simultaneously operated, which is preferable.

The above-mentioned radio telephone can be realized by using any function of a mobile telephone, a car telephone and a PHS as a radio telephone means, but it is most preferable that the radio telephone is realized by the PHS. PHS is convenient for users because it is the simplest wireless telephone means, but because of this, it is a wireless communication network in which it is relatively difficult to ensure constant communication. This is because the effect becomes remarkable.

The radio calling means is realized by using a so-called pager function, but if a circuit configuration common to the radio telephone means and the radio calling means, such as a power supply circuit and an amplifier circuit, is used in common, a radio telephone can be used. It can be made compact and inexpensive.

Further, the wireless telephone according to the present invention requires a display section for the wireless calling means to display in accordance with the message information. However, when only the wireless telephone means operates, the display section is used for the wireless telephone means. Can be used as For example, as the use of the display unit by wireless telephone means,
There is a status display such as confirmation of the entered phone number, remaining battery power, and call amplification.

In addition, the above-mentioned display section is used as an additional function display section related to the telephone such as a telephone number book or a scheduler, and the numeric keypad (numerical key or symbol key) essential to the wireless telephone means is used as the input section. Good.

As another aspect of the line connecting device of the present invention, the line connecting device is provided with voice input means, and voice input from the telephone is voice-recognized, and a message corresponding to the voice is displayed as message information. A configuration is conceivable in which the transmitting means transmits to the wireless calling means. In this case, since the message information is generated from the voice by the voice input means and the message information transmission means, the button operation of the touch-tone phone becomes unnecessary. This line connection device transmits message information corresponding to the voice inputted from the telephone by the voice inputting means and the message information transmitting means to the wireless calling means, and the voice is a number or symbol provided on the numeric keypad rather than a natural language. A combination is also suitable. This is because the processing load required for voice recognition can be reduced by limiting the range of input voice. Further, by using the limited voice as a numeral or a symbol provided on the ten-key pad, the message transmitting method conventionally used in the wireless calling machine can be applied.

It should be noted that the means for performing voice recognition is simple to be provided in the form of being connected to the line connection device, but it may be built in the radio telephone device. In this case,
The voice signal may be transmitted as it is, the voice may be recognized within the wireless telephone device, and the display may be performed.

BEST MODE FOR CARRYING OUT THE INVENTION Next, preferred embodiments of a wireless telephone and its line connection device according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a mobile communication service network constructed by using a wireless telephone as an embodiment of the present invention as a communication terminal. This mobile communication service network
It is configured using the system of a personal mobile phone (PHS) and pager. As a PHS system, an area station EKm (m = 1, 2, ...) Covering an area divided into a large number of small areas Em, a main station CK connected to these area stations EKm, and a main station CK And a public telephone line PN for connecting to the telephone TPf (f = 1, 2 ...). Further, as a pager system, a pager station PK for paging, which is connected to a public telephone line PN and wirelessly calls and sends a message in response to a call request and message information input from a normal telephone TPf, is provided. .

The area station EKm outputs position information at a predetermined interval, and the radio telephones TLn (n = 1, 2 ...) In the area receive this position information and previously receive their own position information. The position information received and stored by is compared. As a result of the comparison, if the positional information is different, it can be determined that the wireless telephone TLn has moved in the area. In this case, the wireless telephone TLn outputs the identification signal to the area station EKm. The area station EKm that has received this identification signal transmits this information to the main station CK that controls the entire system. Therefore, the main station CK can centrally manage the information regarding the wireless telephone TLn existing in the area station EKm under its control.

The main station CK includes a well-known CPU5, ROM7,
A digital type exchange (not shown) including a RAM 8 and the like, a voice recognition unit VR for recognizing a real voice and a voice synthesis unit VG are provided, and a signal is transmitted via a exchange for connecting a telephone line and a public telephone line PN. It has an I / O interface for input / output, a hard disk for storing information in a nonvolatile manner, and the like. Calling stations PK for pagers are well known,
The PHS main station CK has almost the same configuration, but does not have a function of selecting the area station EKm or performing a calling operation via the area station EKm.

Next, the structure of the wireless telephone TLn will be described. FIG. 2 is a block diagram showing the internal configuration of the wireless telephone TLn. As shown, this wireless telephone TL
n is configured around the base band circuit 10,
Oscillator 12, RF unit 14, power supply circuit 16, protocol ROM 20, ADPCM 22, external microcomputer 24, liquid crystal display panel (LCD) 26, 10 keyboard 28, non-volatile memory 30, speaker 32, microphone 34, external crystal oscillator. 38 and the like. As the base band circuit 10, a one-chip LSI designed exclusively for PHS and pager is sold (for PHS, for example, TLCS-90 manufactured by Toshiba Corporation).
0 / L), two functions can be easily configured by using them together. The internal structure of the RF unit 14 is well known, so a detailed description thereof will be omitted, but an amplifier for amplifying the signal from the RF unit 14, a modem excluding the carrier wave, a decoder for decoding the signal, and an area station and a telephone terminal device peculiar to PHS. Time-division multiplex / time-division bidirectional transmission (TD) for exchanging data by dividing into 4 channels
MA / TDD) circuit, logic for controlling these, control logic, RF unit 44 for receiving radio signal for pager, ID circuit 46 for detecting own telephone number from the radio signal, own telephone number is transmitted. A message extraction circuit 48 for extracting a signal after the ID circuit 46 detects that the message has been output as a message, a message output section 50 for inputting the extracted message to the external microcomputer 24 for displaying on the LCD 26, and the like. Has been done.

The RF unit 14 is a unit that receives a signal transmitted by radio waves or transmits a signal used for output, and is suitable for the PHS frequency band. Although only the antenna 12 is shared in this embodiment, the RF unit 14 itself may be adapted to the frequencies for PHS and pager, and the RF unit 14 may be shared by both parties. The protocol ROM 20 is a memory that stores a protocol for PHS communication and a protocol for pager reception.
The ADPCM 22 is a chip that processes input / output of audio, and by performing differential amplification, processing of an audio signal in a wide band is realized with a small number of pits. The external microcomputer 24 performs an arbitration function for operating the baseband circuit 10 for PHS and pager in a standby state in a time-sharing manner, various displays on the LCD 26, and key input from the keyboard 28. Responsible for reception. The nonvolatile memory 30 stores therein a telephone number, an identification number, an abbreviated number, a fixed message dedicated to pager, etc., which is given to itself for two wireless communications for PHS and pager.

The RF unit 44, the ID circuit 46,
Message extraction circuit 48 and message output circuit 50
Corresponds to a so-called pager receiving unit, and the received message is sent to the LC via the external microcomputer 24.
It is configured to be displayed on D26.

In the mobile communication system described above, the wireless telephone TLn has the external microcomputer 2
In the standby state under the control of No. 4, it operates as a mobile phone for PHS or as a pager by time division. That is, when operating as a mobile phone for PHS, it outputs an identification signal only when it moves in the area in which it is present, and requests the area station EKm to update the registration. Upon receiving this identification signal, the area station EKm executes the terminal signal reception processing routine shown in FIG. When this process is activated, first, a process of acquiring the identification number (ID) and the telephone number assigned to the wireless telephone TLn from the wireless telephone TLn is performed (step S1).
00). Next, the main station CK that manages the area station EKm
The user is requested to register the area code managed by itself, the ID of the wireless telephone TLn that has received the service request, and its telephone number (step S120).
If the wireless telephone set TLn has moved from another small area Em managed by the same main station CK, the main station CK already has a record of the wireless telephone set TLn. Will be updated. These data are stored in the hard disk HD in the main office CK. In addition, one wireless telephone TLn
It is normal that information can be exchanged only with the contracted specific main office CK, but it is also possible to exchange information (including a call) with another main office CK by using the so-called roaming function. . Therefore, the roaming function can be used to register data with the main office of another contractor.

On the other hand, when the radio telephone TLn is operating as a pager under the control of the external microcomputer 24, the telephone number transmitted from the pager calling station PK is detected, and the ID circuit 46 determines its own. Determine if it matches the pager phone number. Then, only when the call is for the self, the call is answered and the message information is received.

The wireless telephone TLn of this embodiment having the above-described configuration has both the certainty of the pager capable of constant communication and the large amount of information transmitted by the PHS, and is an ideal mobile communication service. Can enjoy. Moreover, because these functions are integrated,
This is a communication terminal having excellent portability as compared with the case where the PHS and the pager are carried separately. Most of the functions of the PHS and the pager are common, and as shown in FIG. 2, the antenna, the power supply circuit 16, the protocol ROM 20, the external microcomputer 24, the liquid crystal display panel (LCD) 26, and the 10 keyboard. 28, a non-volatile memory 30, many electric circuits such as a speaker 32,
Since the electric element is also used, the operating rate of the device is increased, and the entire device is downsized and inexpensive.

A radio telephone T having such an excellent effect
In order to make the best use of Ln, the main station CK, which is in charge of the overall control of this embodiment, manages the wireless telephones TLn existing in the small areas Em managed by them as described above. When the call request is received, the call control routine shown in FIG. 4 is executed. The call control routine shown in FIG. 4 is executed by the main station CK, and it is assumed that the telephone TP1 outputs the telephone number of the wireless telephone TLn trying to make a wireless call via the public telephone line PN. When the telephone TP1 is hung on, the main office CK starts the service and the public telephone line PN
First, a process for obtaining a PHS telephone number is performed via (step S140). And normal call processing,
That is, the call signal is wirelessly transmitted from the area station EKm that manages the wireless telephone TLn requested by the telephone TP1 (step 150). Then, it is judged whether or not the line connection between the telephone TP1 and the wireless telephone TLn is successful by this calling process (step 160), and if the connection is successful, the call control routine is ended. That is, when the radio telephone TLn operates as a PHS by time division, it receives a call signal from the area station EKm, normal line connection is made, and call control is completed.

On the other hand, even if the calling process of step 140 is performed, the line is not available due to factors such as shortage of communication channels, communication of the wireless telephone TLn, the user outside the communication area, or powering off the PHS receiver. If the connection cannot be established, "the fact that the line connection failed" and "the necessity of calling by pager" are given to the caller of the telephone TP1.
The voice synthesizing unit VG is operated to contact the user who called by the synthesized voice (step 170). Then, when a real voice indicating that it is necessary, for example, a natural language such as “Yes”, “Necessary”, and “YES” or a predetermined reserved word “1 (1)” is returned through the telephone TP1, this is returned. The voice recognition unit VR recognizes and determines whether a call is necessary (step 180). If it is determined in step 180 that there is no need, the call control routine is terminated, but if it is determined that there is a need, the process proceeds to the pager call process of step 200 and the subsequent steps.

In the pager calling process, first, the voice synthesizing unit VG inquires by the synthesized voice whether or not there is a message to be transmitted by the pager function (step 200). On the other hand, the caller of the telephone TP1 may respond in the form of designating a fixed message by uttering a message in a natural language or numbers and symbols, or as in the case of a conventional pager. You can reply by operating the push button provided in. For example, say "Contact home as soon as possible" as a message in natural language, pronounce "# 10 # (Sharp / Ichi / Zero / Sharp)" as a standard message, or actually operate the touch-tone as "# 10 #". To do. Of course, since the message may be unnecessary because it is merely a call, the input from the caller as described above is accepted only for a predetermined time after the inquiry of the message in step 200, and the message is recognized by the voice recognition function. Confirm (step 210). Then, the telephone number for pager stored in the hard disk HD corresponding to the telephone number for PHS acquired in step 140 is retrieved (step 220), and the retrieval is made to the calling station PK for pager. Output the phone number and message information for the selected pager (Step 2
30), the program ends. Here, the message information is the operation signal "# 10 #" of the touch-tone phone corresponding to the voices such as "Call home immediately" or "Sharp / Ichi / Zero / Sharp". Is the same as the signal for a normal pager call request input from a general telephone TP1.

By this call control routine by the main office CK, the pager PK for pager operates in the same manner as a normal pager call request, and sets the area to be called from the area code or the like of the inputted telephone number. , The pager PK for the area is controlled to perform the calling process until the incoming call is confirmed, and when the incoming call is confirmed, a message is output. And the wireless telephone T
When Ln operates as a pager by time division, it receives a calling signal and a message from the calling station PK, generates a chime sound to notify the incoming call, and displays the message on the LCD 26.

By the call control of the main station CK described above, the caller of the ordinary telephone TP1 is connected to the line with the wireless telephone TLn by a simple operation of only inputting the telephone number for PHS, and the amount of transmitted information is changed. You can make many calls. Also, when the call is made, the wireless telephone TLn is talking,
Even if the line connection fails due to lack of communication channels, the user is out of the reception area, or the power of the PHS unit is turned off, the wireless telephone TLn can respond to the voice from the main station CK in natural language. And you can send a simple message securely connected to the line. Therefore, the user only needs to remember the line connection operation in PHS, that is, the telephone number, in order to connect to the wireless telephone TLn.
You don't even need to know the complex numbers and numbers that represent pager phone numbers and messages.

The embodiments of the present invention have been described above.
The present invention is not limited to such embodiments, and it goes without saying that the present invention can be carried out in various modes without departing from the scope of the present invention. For example, a pager calling station PK having a function of directly transmitting a voice or digital signal using FM radio waves can be used to directly transmit voice or a digital signal having a large amount of information to the wireless telephone TLn. It doesn't matter.
