Abstract

PURPOSE:To obtain a voice pager which can hear the voice data of a sender timely in addition to a telephone number, etc., which are the existing transmission information. CONSTITUTION:When a voice pager 6 receives digital data, a CPU 10 stores the digital data to a memory 12 for data. When the receiving message is sent, a receiving person sees the telephone number, etc., stored in the memory 12 for the data with the operation of a switch 16 and can further hear the voice data such as the voice of a caller. Since the receiving content is stored in a memory, it is displayed at the time of the necessity, and the voice can be also heard.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice pager that can send a large amount of information to people outside the home using a telephone network, and a data receiving and transmitting system.

[0002] Conventionally, when receiving a pager call, only when the user knew the person who called the pager, a call was made from a nearby telephone to the memorized phone number of the person calling the pager.

[0003] Recently, due to the complexity of business, multiple calling numbers are provided, and a ringing pattern or display lamp corresponding to the caller's number is set, so that the person who is calling can be identified and the caller can be called. Some devices have a multi-call function.

[0004] However, it is cumbersome to memorize the telephone numbers of a plurality of parties, and may lead to errors such as dialing the wrong telephone number.

For this reason, for example, Japanese Patent Application Laid-Open No. 62-6833
As disclosed in Publication No. 2, multiple telephone numbers are stored in advance in the register, and if the calling number matches the register, the corresponding telephone number is automatically displayed on the pager along with the ring tone. In addition, there are devices that transmit a signal encoded by a pulse method over the air, and display a telephone number on a pager along with a ringing tone.

[0006] However, if you cannot confirm what kind of requirements are by phone number, you do not know the importance of the requirements,
In the case of multi-call, it becomes more complicated.

[0007]Furthermore, there are many cases in which information is unilaterally conveyed by the caller, rather than information that is obtained by calling the other party.

[0008]

[Problems to be Solved by the Invention] The present invention provides a voice pager that can listen to the caller's voice data in a timely manner in addition to existing transmission information such as a telephone number, and in particular a data reception and transmission method used for this purpose. The purpose is to submit.

[0009]

[Means for solving the problem] A receiving means for receiving digitally modulated radio waves, a data memory means for storing the received data, a display means for displaying the stored data, and an outputting a received message after storing the data. 1. A voice pager (claim 1) comprising: a voice pager that selects a data memory bank by operating a switch and converts received data into voice by D/A converting the received data.

[0010] When an incoming call is received using the telephone line network, a response message is sent, an ID and a voice message are accepted, and the voice data of the voice message is D/A.
A data reception/transmission method (claim 3) in which a conversion device converts the signal into a digital signal and digitally transmits the signal to each transmitting station.

[0011]

In the voice pager according to claim (1), when digital data is received, the CPU stores the digital data in the data memory.

[0012] When a received message is issued, the recipient:
By operating a switch, you can view telephone numbers stored in the data memory and listen to voice data such as the caller's voice.

[0013] Since the received contents are stored in the memory, they can be displayed when necessary or at an appropriate place, and the audio can also be heard.

In the data transmission method of claim (3), when a central control station is called using a telephone line, the central control station sends a response message to the caller and receives an ID and a voice message.

[0015] The central control station converts the voice data of the caller's voice message into a digital signal using a D/A converter and transmits the digital data to each transmitting station. data can be handled.

[0016]

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 shows an overview of a system for transmitting a message from a caller to a user carrying a voice pager.

The usage method will be explained with reference to the system flowcharts shown in FIGS. 2 and 3. First, a caller calls the central control station 3 using the telephone 1 and its telephone line network 2 (step 1). ).

[0018] A recorded response message from the central control station 3 is sent to the caller's telephone 1 (step 5), and the user is instructed to enter the user's ID and, if necessary, the telephone number that the user wants to be called. , followed by an instruction to enter a message.

The caller enters the user's ID and telephone number if necessary (step 2), then inputs a message from the handset of telephone 1 (step 3), and hangs up the telephone (step 4). ),finish.

The central control station 3 accepts the user's ID (step 6), and upon confirmation, accepts a voice message (step 7).

The received voice message and other data are all digitized by the computer 4 using an A/D converter (step 8), and the reception is completed (step 9).
), the digital data is sent to each transmitting station 5, 5...
Send (step 10).

The transmitting station 5 transmits the digitized voice data to the user's voice pager 6 by radio (radio waves) as a digital signal.

FIG. 4 is a block diagram showing the mechanism of the voice pager 6, in which 7 is an antenna, 8 is a receiving section, 9 is a display section for displaying numbers, characters, etc. on a liquid crystal display, 10 is a CPU, 1
Reference numeral 1 is a ROM in which a received message notifying reception has been recorded in advance, 12 is a data memory with a plurality of banks, 13 is an audio conversion unit that converts digital data into analog data as voice, 14 is an amplifier, and 15 is a A speaker 16 is a control switch provided in the box of the voice pager 6.

To explain how to use the voice pager 6 using FIGS. 4 and 5, first, the antenna 7 receives radio waves,
When the data is sent to the receiving unit 8, the CPU 10 determines whether it is its own ID (step 11).

If it is not your own ID, discard the data and exit; if it is your own ID, save data memory 1.
2, for example, bank 1 (step 12).

In response to this, the received message recorded in the ROM 11 is played as audio from the speaker 15 via the audio converter 13 and amplifier 14 (step 13).

[0027] The user confirms the acceptance (step 14).
), the user can press the switch 16 to turn off the sound, and then operate the switch to check the phone number and who is calling on the display 9, or play the voice message from the speaker 15 by operating the switch. You can also do it.

By operating a switch, the data of each bank (reception time, ID, etc.) is displayed on the display section, and the digital data in the bank is reproduced into analog data by D/A conversion in the audio conversion section 13, and is output from the speaker 15. Since the user can listen to the sender's message, the user can replay the received data at any time, any place, and any number of times.

Each bank may be assigned to one sender, and when there is a shortage of banks, data may be erased starting from the oldest bank.

[0030] Also, by entering the caller's special ID, the entire bank can be used to store long-term messages of the caller.

[0031] Since the message is transmitted using digital data, the confidentiality of mobile communication is greatly improved.

[0032]

[Effects of the Invention] The present invention has the following effects. (a)
In addition to existing transmission information such as phone numbers, you can listen to the caller's voice data from any location. (b) Since digital data is used, the possibility of wiretapping is drastically reduced.
