2. Description of the Related Art Radio calls are made by individually assigning subscriber phone numbers to small portable receivers, dialing the numbers from the subscriber phone, and emitting radio waves from a wireless calling base station.
This allows individual mobile receivers to be called up. There are three types of wireless calling methods: a tone system that generates a sound, a number display system that displays numbers, and a message display system that displays a message.The wireless line signal system is the NTT system in Japan, the POCSAG system, and other systems internationally. niG
There is an olay method. The NTT system uses a 280 MHz band digital system, employs FSK modulation and BCH code error correction, and has also introduced dual alcohol service since 1981.

[0003] When a subscriber goes out, he or she carries a portable receiver with a calling number similar to that of a regular telephone. When you want to contact that subscriber, you dial the calling number from a regular telephone, a signal is sent out from the base station, and when the signal is received by the corresponding receiver, a ring tone sounds. The called subscriber contacts from a nearby telephone. Dual-alcohol service makes it possible to distinguish between emergency calls, regular calls, calls from work, and calls from home by adding two call numbers and two types of ring tones. Because a wide coverage area is required, including inside buildings, multiple base stations (7 in Tokyo) are installed within the city to ensure sufficiently high electric field strength over a wide area. Also, from April 1988, a service for portable receivers with display was started. The portable receiver with a display has the function of displaying 12 digits of numbers and simple symbols based on input from a touch-tone phone.

[Problems to be Solved by the Invention] On the other hand, as seen in recent years in families where both parents work, the range of activities of each member of the family is wide-ranging, and there is a strong tendency for their living hours to differ. Under these circumstances, the importance of communication among family members and emergency notification for all family members in case of an emergency is becoming more and more important.

[0005] Therefore, in the future, it is thought that the use of wireless calling not only for business purposes but also for family use for communication between households will increase more and more.

[0006] However, in conventional wireless calling, it is intended for business use and requires an individual contract for each receiver.
Since the calling numbers of each receiver are completely different,
Simultaneous calling to multiple mobile receivers was not possible.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a radio paging receiver which is convenient for home use and is capable of simultaneously calling each group.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the radio paging receiver of the present invention receives a calling number consisting of a common number assigned to each group and an identification number for identification within the group. , is characterized in that it displays a message in response to a calling number that includes a unique identification number preset for each receiver, and also displays a message in response to a calling number that includes a specific identification number that indicates simultaneous calling. do.

[0009]Furthermore, the receiver of the present invention displays an identification number indicating who the sender is along with the received message when the received identification number is an identification number assigned in advance to the receiver. On the other hand, when the received identification number indicates simultaneous calling, the specific identification number can be displayed together with the received message.

0010

[Operation] In the present invention, when making an individual call, the information to be conveyed (for example, a telephone number) is transmitted to any radio paging receiver, and an identification number is sent to notify the sender (caller). Enter. On the other hand, when making a simultaneous call, information to be conveyed is transmitted to all radio paging receivers, and a specific identification number (for example, 0) is input in order to notify everyone that the call is being made. In this way, the present invention can be owned by each family member, and can be used to call all family members at once and communicate with each other (message sending and receiving).
This provides a wireless paging receiver that is capable of This radio paging receiver has the following two types of functions compared to conventional radio paging receivers. In other words, a common number can be used for calling and sending and receiving messages between each radio paging receiver, facilitating mutual communication. In addition, an automatic notification device (installed in the house)
This makes it possible to reliably notify all family members with a single call (using the simultaneous call function).

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the overall schematic configuration of a radio paging system to which the present invention can be applied. When the calling number assigned to each radio paging receiver 8 is dialed from the general telephone 1, a signal is transmitted from the central base station 6 and peripheral base stations 7 through the local exchange 2 and the central office 3, and the signal is sent to the corresponding receiver. 8
If the message is received by the receiver 8, a ring tone will sound and a message will be displayed. The central station 3 is a radio paging device 4
and an encoding device 5.

FIG. 2 shows the system configuration of FIG. 1 in more detail. There are various fixed telephone networks that can be used, including public telephone networks, private lines, and public data networks such as packet networks, but NTT's public telephone network is generally used. The exchange 11 includes a digital exchange 12 and a message receiving device 13.
Consists of. For radio calling, it is necessary to increase the calling probability over a wide area, so there is a regional control station 14 for each region, and a plurality of transmitting stations 15 are geographically placed under it to ensure the transmission of calling radio waves. . The exchange 11 and each regional control station 14 are, for example, No. 7 signal system will be adopted. A multi-station simultaneous transmission technique is used between the regional control station 14 and the transmitting station 15 under its control, which transmits the same paging signal all at once.

FIG. 3 shows an example of the structure of a call number representing the features of the present invention. The calling number in this embodiment that is assigned to each portable radio calling receiver 8 is a common number (i.e.,
(contract telephone number) and an identification number that identifies each receiver. For example, the first eight digits of the common number are used, and one common number is assigned to one group. For example, the last digit of the identification number (
or the last two digits) and are used to distinguish between individual receivers within a group. For example, in the example of FIG. 3 for a family of four, identification number "1" is the radio paging receiver for the father, identification number "2" is the radio paging receiver for the mother, and identification number "3" is the radio paging receiver for the mother.
” can be assigned to the first child radio paging receiver, and the identification number “4” can be assigned to the second child radio paging receiver. In addition, the identification number “0” can be assigned to all members of a group at once, as described later. Used for simultaneous calls.

FIG. 4 shows a specific example of input on the transmitting side and display on the receiving side when calling receivers in one group individually. In this case, the input on the sending side is the common number for each group (for example, 1234-5678), the individual call identification number of the other party (one of 1 to 9, for example, 4), and the information to be conveyed (as a message, for example, 000-5678). 0000), the sender's identification number (one of 1 to 9, for example 1), and is carried out by dialing in these data with subscriber telephone 1. Then, the received information to be conveyed and the sender's identification number (for example, 1) are displayed on the display screen of the corresponding receiver (for example, 8D with identification number 4) of the other party that received the above input information on the sender side. Ru. Thereby, for example, the second child who has the receiver with the identification number 4 can confirm that the call is from the father who has the receiver with the identification number 1.

FIG. 5 schematically shows the signal flow in the case of individual calling in the embodiment of FIG. When the central station 3 receives input data from the transmitting side as shown in FIG.
7, a unique pulse signal (call signal) corresponding to the combination of the common number (1234-5678) and individual call identification number (4) is transmitted, and when the corresponding receiver 8D receives this signal, it transmits the information to be transmitted (e.g. Phone number 00
00-0000) and the sender's identification number (1) are wirelessly transmitted. The corresponding receiver 8D generates a ringing tone in response to its own assigned number (common number + identification number), and displays the information to be conveyed and the sender's identification number on the display screen as shown in Figure 4. .

FIG. 6 shows a concrete example of the input on the transmitting side and the display on the receiving side when simultaneous paging is performed for an entire group. In this case, the sender's input is the common number for each group (for example, 1234-5678), the general call identification number (0), and the information to be conveyed (for example, the telephone number 000
0-0000), and in addition to dialing in from the subscriber telephone 1, input from an automatic notification machine, etc., which will be described later, can be applied. Then, all the receivers (for example, 8A to 8D) having the corresponding common number that received the above input information on the sending side display the received information to be conveyed and "0" indicating that it is a general call on the display screen. . That is, each of the radio paging receivers according to the present invention has a common number and an identification number (
While receiving the call signals of the combinations 1 to 9),
It also has a function to receive a call signal of a combination of a common number and a simultaneous call identification number (0), and the identification number is "0".
In this case, it is programmed in advance to display that "0" at a predetermined position on the display screen.

FIG. 7 shows an example of application of simultaneous calling in the embodiment of FIG. In this example, an abnormality report from an automatic notification device 31 with a communication function installed in a subscriber's home serves as an input for a simultaneous call as shown in FIG. For this reason, the automatic notification device 31 is preset in an internal memory (not shown) to transmit the contents input on the sending side shown in FIG. It is made different for each sensor connected to the machine 31. For example, when the fire sensor 32 detects an abnormality,
A code (for example, 109) indicating "fire outbreak" is the information you want to convey, and when a security sensor (not shown) detects an abnormality, a code (for example, 109) indicating "intrusion by a suspicious person" is sent.
10) is the information you want to convey.

When the automatic notification device 31 detects an abnormality from a sensor, it transmits an abnormality notification corresponding to the content of the abnormality through a public communication line in a format as shown in the upper part of FIG. When the central station 3 receives input data from the transmitting side as shown in FIG. 6, it sends a common number (123
4-5678) and the general call identification number (0), and the information to be conveyed (0000-0000) are wirelessly transmitted. All corresponding receivers 8A to 8D that have the same common number (1234-5678) respond to the common number and identification number (0) by emitting a ring tone and displaying a message as shown in FIG. 6 on the display screen. The information you want to convey and “0” indicating that it is a general call
” will be displayed. In this way, it is possible to make a simultaneous call that will surely inform the entire family of an abnormality with a single report.

[0020] In the embodiments of the present invention described above, a family unit was exemplified as a specific example of a group to which a common number is assigned, but the present invention is not limited to this. It can also be used for internal security systems, etc. When applied to a nursing system, a common number may be assigned to each nurse group, and simultaneous call input may be used, for example, to detect an abnormality in a patient's electrocardiogram. Furthermore, the input order and display order of identification numbers are not limited to this embodiment. For example, it goes without saying that the identification number may be displayed at the top position. Furthermore, it goes without saying that the information (message) to be conveyed is not limited to the number of digits in this embodiment, and can also be converted into text and displayed using an IC-ROM on the receiver side. Further, the delimiter for display is not limited to a hyphen (-), but also a slash (/), a semicolon (;), etc. can be used. Furthermore, the present invention does not require any new hardware, and can be implemented by modifying software compatible with the method of the present invention.

[0021]

[Effects of the Invention] As explained above, according to the present invention,
The following effects can be obtained.

[0022] Since an identification number is added in addition to the contract telephone number to the calling number for calling and message transmission/reception between each radio paging receiver, both simultaneous and individual calling is possible.

[0023] Furthermore, as an example of its application, in a system combined with an automatic notification device, it becomes possible to notify all family members of an emergency situation in the house using the simultaneous call function.

[0024] Since the above call number can be a combination of a common number and an identification number, mutual communication within the group is facilitated.

[0025] By making a contract for each common number rather than for each receiver, the number of receivers within a group can be increased or decreased freely.
