DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling device, and more particularly, to a center of a terminal by a user.
The present invention relates to an ID automatic registration type wireless selective calling apparatus capable of registering a (selectable calling number) and calling a wireless selective calling receiver.

[0002]

2. Description of the Related Art Conventionally, the ID of a radio selective calling receiver is a business entity that performs radio selective calling (hereinafter, a center business operator).
Therefore, at the time of contract, the information is registered and managed by the wireless calling device without being basically duplicated for each terminal. On the other hand, as a known document describing a broadcast-type wireless paging method, for example, Japanese Patent Application Laid-Open No. HEI 3-18762
No. 7 publication. According to this publication, an arbitrary address can be set on the receiver side, and when the transmitting side transmits one message, all the receivers having set the address of the message receive this, and the same as the calling process is performed. According to the configuration, in order to realize a broadcast-type information service, input means for inputting a service number from outside, a conversion device for converting the service number into an address, and storing the address A predetermined number of service registers are provided, and the contents of the message register are compared with the value of the own address register and the value of the service register, and when they match, a call and a message are displayed. However, even with this method, the relationship between the service number and the address needs to be stored in the terminal in advance, and if a broadcast communication is to be performed on an occasion, the address must be written by the center operator each time. Needed.

[0003]

When a general user obtains a radio selective calling receiver, the general user must always inform the center operator of the fact and have the ID written by a dedicated writer. On the other hand, even in the center business, a service cost for writing the ID is required for each general user, and in particular, the labor cost is very large. As described above, the reason for the extra work and cost is, in part, to maintain the secrecy of the radio selective calling system, which is a communication means. It is well known to collect. However, for a center business that does not exhibit a contract system, if the confidentiality is further examined, it is also possible to provide a wireless paging service as before.

[0004] On the other hand, when there is an opportunity to use the radio selective call service in a group and perform simultaneous broadcast, a method of using an ID common to the group is generally used as a method of efficiently using radio waves. In this case, the user has to apply to the center operator and write the common ID for the number of people in the group. However, this is inconvenient for a user who wants to freely set a group whenever necessary, and a terminal that allows the user to freely write an ID is effective to meet the need.

The present invention has been made in view of such circumstances, and provides a non-contracted wireless selective call service while maintaining confidentiality. Providing a calling device;
It is another object of the present invention to provide an ID automatic registration type wireless selective call apparatus having a method of easily realizing a flexible group configuration.

[0006]

In order to achieve the above object, the present invention provides (1) a line connection unit connected to a telephone line from an exchange, and a multi-frequency signal (hereinafter referred to as DTMF) received through the line. And a central processing unit having software for processing data obtained by the multi-frequency signal receiver and forming data for wireless calling, and processing. A selective call number (hereinafter, referred to as a radio selective call receiver) of the radio selective call receiver called from the radio selective call device, comprising a storage unit for storing the obtained data, a radio transmission unit for transmitting a call signal, and an antenna for transmitting a radio wave. ID) is automatically registered when the selective call number given to each terminal in advance is designated from the radio selective call receiver, and the subsequent call is performed. In addition, (2) the selective call number given in advance to each terminal is indicated, and at the same time the selective call number freely set at the terminal is also indicated. When the freely set selective call number is not already registered, the two selective call numbers are automatically registered in correspondence with each other, and in the subsequent call, a call is requested by the freely set selective call number. However, in practice, a call is made using the selective call number previously given to the terminal at the time of purchase. (3) In the above (2), the freely set selective call number is registered for an unlimited number or for a certain number of persons. Yes, but in case the selected call number overlaps with another user's name, the user's name is automatically registered with the corresponding name, and the call is made when a call is requested by the selected call number. The user is confirmed by voice guidance, and if they match, a call is made with the selected call number previously given to the terminal corresponding to the selected call number. (4) In the above (2), the antenna A radio selective calling receiver having a radio receiving unit, a display, a ringing device, and a central processing unit controlling each unit, a switch group for freely setting a selective calling number, and input by the switch group A storage unit for storing the selected call number; when an optional call number is set, calling is performed by using the set selected call number at the time of calling; In 4), an unlimited or fixed number of terminal selective call numbers can be registered in the freely set selective call number, but the number of registered users can be limited and changed. It is also possible to limit the number of users who are additionally registered, and when calling, it is characterized in that calling is performed using a designated selective calling number, that is, a terminal selective calling number or a set selective calling number. .

[0007]

[Operation] When the user purchases the radio selective calling receiver,
First, a terminal ID registered and inscribed in the receiver at the time of shipment is notified to the center company by a multi-frequency signal (DTMF: Dual-Tone Multi-Frequency) signal through a telephone line. The radio selective calling device immediately collates the terminal ID, registers if not registered, and sets it as the ID for future calling. On the other hand, if the ID has already been registered, the calling mode is set and the calling is started.

If the ID can be freely set by the user, the center operator is accessed in the same procedure and an arbitrary ID (hereinafter, free ID) is input instead of the terminal ID. In the same way, the radio selective calling device immediately sets the free ID.
Is collated, and if not registered, input of a terminal ID is prompted, and both IDs are registered in association with each other. On the other hand, if the ID has already been registered, the calling mode is set, the terminal ID is converted to the terminal ID corresponding to the free ID, and the calling is started.

[0009] Further, in the case where the same free ID can be shared by a plurality of persons, the free IDs input in the same procedure are registered until the number is predetermined by the center operator. However, when registering
The name of the ID registered user is input simultaneously with the MF signal. On the other hand, when calling, the names of the users belonging to the free ID are sequentially read out by the user's operation, and upon hearing the names, the desired called party is selected. At this time, the radio selective calling device makes a call using the terminal ID of the selected called party. If the number called by the free ID is an unregistered number, the number set by the user on the terminal itself can be registered as the free ID. At this time, the radio selective calling device calls using the free ID.

[0010] Finally, the same free ID is shared by multiple persons,
In addition, the number of persons is determined by the user. When registering an unregistered number as a free ID, first, the number of persons that can be registered is set. The set number can be changed later, and can be registered until the set number is reached. When calling, a flexible service is realized by calling with either the terminal ID or the free ID according to the user's request.

[0011]

Embodiments will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining an embodiment of a wireless selective calling apparatus of the ID automatic registration type according to the present invention.
Reference numeral 10 denotes a telephone line, 11 denotes a line connection unit, 12 denotes an incoming call detection unit, 13 denotes a DTMF (Dual-Tone Multi-Frequency) receiver, 14 denotes a voice generation unit, and 15 denotes a central processing unit (CP).
U), 15a are control units of each unit, 15b is an ID (selection call number) search unit, 15c is a data processing unit, 16 is a storage unit,
7 is an emergency storage unit, 18 is a wireless transmission unit, and 19 is an antenna.

An automatic ID registration type radio selective calling apparatus according to the present invention converts a multi-frequency signal (DTMF signal) received through a telephone line 10 into a binary signal through a line connection unit 11 connected to a telephone line 10 from an exchange. DTMF receiver 13 for converting the digital data into digital data, a CPU 15 having software for processing data obtained by the DTMF receiver 13 and forming data for wireless calling, and a storage unit 16 for storing the processed data And a wireless transmitting unit 18 for transmitting a call signal, and an antenna 19 for transmitting a radio wave. The CPU 15 includes a control unit 15a
And an ID search unit 15b and a data processing unit 15c,
The ID search unit 15b searches or collates the currently registered ID, determines whether or not registration is possible according to a request from the user, and if possible, registers it in the recording unit 16.

FIG. 2 is a flowchart of a radio call apparatus in which a user registers a terminal ID with a center operator. Hereinafter, description will be made in order according to each step (A). The user who has set up the terminal calls the center operator and notifies the terminal ID written on the terminal. At this time, when the incoming call detecting unit 12 detects an incoming signal through the telephone line 10 connected from the exchange, the radio selective calling apparatus detects the incoming signal.
Close the line at 1 (A10-A11). Control unit 15a
Sends voice guidance from the voice generating unit 14 to prompt the user to input a terminal ID.

When the user inputs a terminal ID using a DTMF signal (A12), the terminal ID is converted into a digital signal by the DTMF receiver 13, and the signal is sent to the ID search unit 15b. The ID search unit 15b checks whether the input terminal ID exists in the storage unit 16 (A13). When the ID does not exist, the registration mode is set, and the user is confirmed with the voice guidance (A14).
6 and the emergency storage unit 17 (A15), the line connection unit 11 opens the line and ends the registration operation (A12).

On the other hand, the terminal ID input by the user
When there is, that is, when it has already been registered, the calling mode is set, the user is confirmed to call (A16), and a message input is prompted in the same manner as at the time of registration. When a message is input by the user (A17), the terminal ID and the message are sent to the data processing unit 15c and converted into a signal form of radio selective calling (A18). The processed data is transmitted via the radio transmission unit 18 The radio selective calling is performed from the antenna 19 (A19). Here, in the above operation, if neither the registration (A14) nor the call (A16) is performed, the operation again becomes the ID input operation (A12). (A20).

FIG. 3 shows the user's freedom I in place of the terminal ID.
It is a flowchart at the time of using D. Hereinafter, description will be made in order according to each step (B). Here, B10
B21 corresponds to A10 to A21 in FIG. 2 and the operation is the same. When the user inputs a free ID to the center operator by telephone (B11 to B12), the radio selective calling device collates (B13), and if the free ID does not exist, the registration mode is set. In the case of registration (B14), the user inputs the terminal ID inscribed in the terminal (B41), and the radio selective calling device registers in the storage unit 16 and the emergency storage unit 17 in association with the free ID (B15). ).

On the other hand, when the free ID exists, that is, when the free ID has already been registered, the calling mode is set. When it is confirmed that the user is called (B16), the terminal ID corresponding to the free ID is read from the storage unit 16 (B42), and after the message is input (B17), the terminal ID and the message are sent to the data processing unit 15c. To perform data processing (B18), and a radio selective call is made (B19).

FIG. 4 is a flow chart in the case where a free ID can be shared by a plurality of persons, but a call is made using a terminal ID. Hereinafter, description will be made in order according to each step (C). Here, C10 to C21 and C41 and C42 correspond to B10 to B21 and B41 and B42 in FIG. 3, and the operations are the same. FIG. 5 shows a form of the free ID and the terminal ID registered in the storage unit 16 and the emergency storage unit 17 in the operation. Where 2
0 is a free ID area, 21 is the number of remaining areas, 22 to 27 are terminal ID areas, and terminal ID area 22 is divided into three blocks, 22a is an area number, 22b is a terminal ID, and 22c is name data. , Terminal ID area 23
The same applies to ２７27. Further, the illustrated terminal ID area 22
It is assumed that the number j (registerable number) of to 27 is predetermined.

As a result of collation of the free ID input by the user in the same operation as described above, if the free ID does not exist and the user requests registration (C10 to C14), the remaining area number 21
Is set as the number of registers that can be registered (C51), and input of the terminal ID and the name of the user is requested (C41, C52). Here, the input of the name is, for example, one character by two-digit input, and the first digit is 1 for A-line, 2 is for K-line, ... 0 is for W-line, and the second digit is 1 for A-stage.
2 is the first stage,... 5 is the second stage, regardless of the first digit, the second digit is 6 for a cloudy point and 7 for a semi-voiced point.

Further, when the user presses the second digit, the voice guidance is read out, and the character is determined by the * key.
The name ends with the # key. As described above, when the name is input, the number of remaining areas 21 is reduced by 1 (C53), and registered in the storage unit 16 and the emergency storage unit 17 in the data form of FIG. At this time, the terminal ID exists only in the terminal ID area 22, the terminal ID areas 23 to 27 are empty areas, and the remaining area number k = j-1.

In step C13, the free ID
Is present, that is, when it is already registered, the call mode is set. If it is desired to register the same free ID as its own call number, additional registration can be selected. If you select additional registration, it becomes the additional registration mode (C16, C5
9) The remaining area number 21 is read out. If the remaining area number 21 is not "0", that is, if the terminal ID area remains (C60), the process proceeds to the registration mode step C41.

On the other hand, when the call is selected in the call mode (C16), first, the data of the free ID is read from the storage unit 16, the terminal ID 22b and the name data 22c are read from the j-1st terminal ID area 22, and The user is notified of the name data 22c through the voice generating unit 14 (C54, C42, C55). If this is the other party to be called (C56), the process proceeds to the message input in step C17, and the call is made wirelessly by the terminal ID (C18, C1).
9). If you are not the caller (C56),
It is determined whether there is any remaining terminal ID (C57), and the next data is read (C58, C54).

FIG. 6 is a block diagram of a radio selective calling receiver in which an ID can be set arbitrarily. In FIG.
1 is a wireless receiving unit, 41a is a wireless amplifying unit, 41b is a demodulating unit, 41c is a waveform shaping unit, and 42 is a central processing unit (CP
U), 43 is a storage unit, 43a is an ID-ROM (Read Onl
y Memory) and 43b are RAM (Random Access Memor)
y), 44 is a sounding device, 44a is a buffer, 44b is a buzzer, 45 is a display unit, and 45a is an LCD (Liquid Crystal).
Display) driver, 45b is an LCD display, and 46 is a switch group.

The ID-ROM 43a in the storage section 43 is an electrically readable and writable memory, for example, an EEPROM (El
ectrically Erasable and Programmable ROM), etc., which are not duplicated in advance by the terminal manufacturer.
D, that is, only one terminal ID is written. The switch group 46 may be, for example, a 12-key pad of a telephone so that an ID can be easily input.

FIG. 7 is a flowchart when the user writes the ID in the radio selective calling receiver shown in FIG. Hereinafter, description will be made in order according to each step (R). Free ID
First, the user who wants to write "1" sets the receiver in the registration mode by the switch group 46 (R1). The CPU 42 displays "Register" on the LCD display 45b through the LCD driver 45a (R2). If the registration is successful, the CPU 42 requests an input of an ID (R3). The user inputs a desired ID through the switch group 46 (R3).
The PU 42 writes the ID data into the ID-ROM 43a (R5) and completes the registration (R6).

When called, the calling signal received by the antenna 40 is amplified by the radio amplification unit 41a, demodulated by the demodulation unit 41b, shaped by the waveform shaping unit 41c, and converted into a binary digital signal. Become. The signal is sent to the CPU 4
After the error is corrected in step 2, the message is compared with one or more IDs stored in the ID-ROM 43a, and if at least one matches, the message is stored in the RAM 43b, the sound signal is sent to the buffer 44a, and the buzzer 44b is turned off. Ring to alert you of incoming calls. At the same time, an incoming call display signal is sent to the LCD driver 45a, and the LCD display 45b indicates that there is an incoming call.

A method for realizing a call by a free ID using the receiver can be given in the flowchart of FIG. According to this flow, as described above, since the ID is not duplicated on the center side, it is possible to perform the wireless calling service without causing confusion.

FIGS. 8 and 9 are flow charts in the case where any of the free ID and the terminal ID can be called.
Hereinafter, description will be made in order according to each step (D). Here, D10 to D21, D41, D42 and D51 to D6
0 indicates C10 to C21, C41, and C42 in FIG.
And C51 to C60, and the operation is the same.

When the user inputs a free ID and the free ID does not exist (D10 to D13), the mode is the ID registration mode (D14). Up to this point, the process is the same as described above, but here, the user inputs the number of terminal IDs that can be registered for the free ID, that is, the number of registrable numbers j (D61). In this case, FIG.
Is a constant area 31 shown in the lower part of the figure, and the constant area 31 is composed of a registrable number 31a and a remaining area number 31b. Step D6
When the number 31 that can be registered is input in step 1, the remaining area number 31b is determined (D51) and the terminal ID is input (D4).
1), name input (D52), calculation of remaining area number 31b (D5
3), and ID registration (D15) is performed, and the terminal ID is registered in the storage unit 16 and the emergency storage unit 17 in the data form of FIG. As described above, the registrable number 31a can be set only by the user who first registers the free ID.

On the other hand, when the free ID exists, that is, it has already been registered, and the call is rejected,
The change mode a can be entered (D16, D62). In the change mode (D62), the user is required to input a terminal ID. When the terminal ID is input (D63), the collation is performed immediately (D64). If the terminal ID exists in the free ID input in step D12, the number of registrable numbers 31a can be changed. Furthermore, if the terminal ID is the k-th terminal ID, that is, the terminal ID registered last in the free ID (D65), the change c can be input as an integer of -1 or more (D66), and the number of registrable numbers 31a
Then, the change c is added to the remaining area number 31b (D68).

That is, when c = −1, the terminal ID of the user who performed the action is erased. If the terminal ID is not the last ID in step D65,
The number 31a of registers that can be registered cannot be reduced, that is, only one or more change c can be input (D67). Further, the user who can register in the increased terminal ID area is restricted, that is, the group constituted by the free ID is closed or inputted (D72). In the case of a closed group, a random number is given as a confirmation code.
Free terminal ID area (36, 37) as shown in
(D73). If the group is an open group in step D72, the confirmation code 36 (37) is set to the initial value, that is, all bits are set to 0 (D74).

If the change of the registrable number 31a is rejected in the step D62, the mode enters the additional registration mode (D59). If additional registration is possible (D60), the confirmation code 36 (37) is input (D70), collation with the confirmation code 36 (37) is performed, and if they match (D71), additional registration is performed (D41, D52, D53, D15). Also,
When a call is requested in step D16, the calling mode is set, and it is input whether to make a personal call, that is, whether or not to call with a terminal ID (D69). If it is not an individual call, a message is input in step D17, and the call is made with the free ID. On the other hand, in the case of a personal call, the process proceeds to step D54, and the terminal ID is determined (D54, D4
2, D55 to D58) and proceed to step D17.

[0033]

As is apparent from the above description, the present invention has the following effects. (1) The selective calling number of the radio selective calling receiver called from the radio selective calling device is automatically registered by the user of the receiver instructing the selective calling number given to each terminal in advance at the time of purchase. , The selected call number is used in subsequent calls. Thus, I
Since D is automatically registered in the center, there is no cost associated with ID management, such as writing an ID that is considered necessary evil for the center operator. (2) The user can not only have his or her easy-to-remember ID as a call number, but also receive a radio selective call service with confidentiality. (3) Even when several persons have the same ID, the radio selective calling service with confidentiality can be received. (4) A group is formed by users having an arbitrary ID setting type radio selective call receiver, and when an arbitrary group ID is set, even if the number of members of the group changes, the group setting adapted to the change is always made.
