Abstract

PURPOSE:To easily confirm whether or not message information has an error. CONSTITUTION:A reception control part 3 once receiving a radio signal from a radio base station decides whether or not the received data has the error from BCH parity bits in the message data. If there is a one-bit error, the error is corrected, but when there is a >=2-bit error, the error can not be corrected, so the data is outputted to a received data storage part 6 together with added data for displaying data including the error in different display mode. A coincidence and similarity detecting circuit 19 compares the message information outputted from the received data storage part 6 with telephone number data stored in a RAM 12 to retrieve telephone number data which matches the message information or is similar to it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an individual calling device having an error detecting function of received message information.

[0002]

2. Description of the Related Art Message information transmitted from a radio base station to an individual calling device (pager) is added with an error check bit in order to detect and correct an error occurring in the process of transmission and reception. ing. For example,
In the poxag method, 10 error correction bits called BCH parity bits are transmitted as part of the message information, and the receiving side determines whether the message information received by the BCH parity bits contains an error. Error correction is being performed.

However, the BCH parity bit can correct only one bit of error, and when an error of 2 bits or more is detected, the display mode of the data part including the error is changed, for example, reverse display or underline display is performed. We are trying to inform that there is a high possibility that the display data is incorrect.

However, even if the part including the error is found, the correct data of the part where the error is displayed cannot be known as it is. Therefore, if a contact telephone number is received as message information and the contact telephone number is displayed as an error, the called person searches the address book for a telephone number similar to the displayed telephone number. It was necessary to judge whether the displayed telephone number was correct or not, and the confirmation work was troublesome.

[0005]

It is an object of the present invention to provide an individual calling device which can easily confirm whether or not there is an error in the message information when the received message information contains an error or when there is a possibility of an error. The purpose is to provide.

[0006]

SUMMARY OF THE INVENTION When the present invention detects an error or the possibility of an error in the received message information, it stores the information matching or similar to the message information including the error, the name and the telephone number. The information retrieved from the storage means and the retrieved information is displayed together with the message information.

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram showing a circuit configuration of an individual calling device according to a first embodiment of the present invention. In the figure, a radio signal transmitted from a radio base station (not shown) is received by the antenna 1 and sent to the receiving unit 2. The receiving unit 2 detects, amplifies, and demodulates the received signal, decodes it into digital data consisting of “0” and “1”, and outputs it to the reception control unit 3.

The reception control section 3 is a circuit for determining whether or not the address code in the digital data matches the calling number of itself stored in the ID-ROM 4.
When they match, the speaker 5 announces that there is a call and sends the message data to be received subsequently to the received data storage unit 6. At this time, the reception control unit 3 determines from the BCH parity bit in the message data whether there is an error in the received data, and if there is an error, corrects the error if it is a 1-bit error.
If there is an error of more than one bit or if there is a possibility of error, the error cannot be corrected.Therefore, in order to display the data including the error in a different display form, for example, the underlined data with error is added. And outputs it to the received data storage unit 6.

The received data storage unit 6 stores the received message data, sends the data to the upper display unit 8a of the display 8 via the driver 7, and outputs it to the match / similarity detection circuit 19 via the gate 14. To do.

The driver 7 uses the message data from the received data storage unit 6, the name and telephone number read from the RAM 12 described later, or the switch SW ₃ described later.
Is a circuit that creates a display signal corresponding to the telephone number data or the like output from the register 20 when is operated. The created display signal is displayed on the upper and lower two stages of the display unit 8a,
It outputs to b and displays those data.

The input section 9 is composed of characters and numerical keys,
It is operated when inputting the name and telephone number to be registered in the RAM 12. The switch SW ₁ is a switch for switching to the data registration mode to the RAM 12, and the switch SW ₁
When the Q output signal of the flip-flop 10 is set to a high level by inputting and a desired character or numerical value is input from the input unit 9, the data is stored in the RAM 12 and displayed on the lower stage 8b of the display 8. ..

The switch SW ₂ is a switch that is operated when sequentially reading the name and telephone number stored in the RAM 12, and every time the switch SW ₂ is operated, the address sequentially incremented with the read signal from the address control unit 11. Is output to the RAM 12 and data is read.

FIG. 3 (a) shows an example of the display when the switch SW ₂ is operated to switch to the telephone number display mode. First, the first address "AOKI 03-3
45-6777 "is displayed, the next name and telephone number are sequentially displayed sequentially each time to operate the switch SW ₂ hereinafter.

The RAM 12 is a memory for writing and reading data to and from a specified address in accordance with the write and read signals from the address control unit 11. As shown in FIG. It is stored in alphabetical order.

The switch SW ₃ is a switch for operating when the received message is displayed together with an underline indicating that an error has occurred, and searching the RAM 12 for the displayed message, for example, a telephone number similar to the contact telephone number. is there.

When the switch SW ₃ is operated, the RS flip-flop 13 is set and the gates 14 and 1 are turned on.
Active signals are given to the control terminals 5 and 16, the inverter 17, the match / similarity detection circuit 19 and the address control unit 11.

When the switch SW ₃ is not operated, the RS flip-flop 13 is in the reset state,
A low level signal from the Q output terminal
The gate control terminals 4, 15, 16 are applied to the match / similarity detection circuit 19 and the like, and the above circuits are inactive. In the reset state, the inverter 1
The control terminal of the gate 18 to which the output of 7 is given is enabled, the gate 18 is opened, and the data of the RAM 12 can be output to the driver 7.

The match / similarity detection circuit 19 compares the message information from the received data storage unit 6 input via the gate 14 with the telephone number data from the RAM 12 sequentially input via the gate 15 to determine whether they match or not. This is a circuit for detecting similar telephone numbers, and when there is matching or similar telephone number data, the telephone number data and name data are output to the register 20.

The register 20 stores the telephone number and name data from the match / similarity detection circuit 19 and outputs the stored data to the driver 7 via the gate 16. Then, the driver 7 displays the telephone number on the lower stage 8b of the display 8.

In the above structure, first, a large number of names and telephone numbers are input to the RAM 12 from the input unit 9 in advance. However, when the message data is received by the antenna 1, this data is stored in the received data storage section 6 and displayed on the upper display section 8a of the display unit 8.

If there is an error (error) in the received data, or if there is a possibility of such an error, the error data for displaying an underline below the character is also stored in the received data storage unit 6. Therefore, for example, "TELL 0
3 (245) 6776 ”, and if two of these“ 6 ”data are erroneous or may be erroneous, the upper display 8a displays“ 6 ”as shown in FIG. 3 (b). "
The underlined state is displayed below.

However, when it is displayed that an error is included in the received message information, the telephone number RAM 12 which is the same as or similar to the contact telephone number displayed by operating the switch SW ₃ is displayed. You can search from and display a matching or similar phone number along with the contact phone number you received, and by comparing the two, you can see if the contact phone number displayed as having errors is really incorrect or not accurate. You can easily check the correct number.

That is, when the switch S ₃ is operated in the display state with an error, the flip-flop 13 is set, and the Q output signal causes the gate 14 to open so that the contents of the received data storage unit 6 are transferred to the match / similarity detection circuit 19. R is sent by the Q output of the flip-flop 13
Detection circuit 1 for all data of AM12 via gate 15
9 out of the data stored in the RAM 12
The telephone number data and name data that match or are closest to the data stored in the received data storage unit 6 are sent to the register 20, and the lower display unit 8 is sent via the gate 16.
Display on b.

An example of the display at this time is shown in FIG. 3 (b).
As shown in the figure, the upper 8a of the display 8 displays a numerical value including an error of the contact telephone number "03-254-6776" together with an underline, and the lower 8b indicates the telephone number stored in the RAM 12 as described above. Similar to "03-245-
Since "6774" is displayed together with the name, both can be compared to know the correct contact telephone number.

When the search for a similar telephone number is completed by operating the switch SW ₃ , the address control section 11 outputs a reset signal to the RS flip-flop 13 to reset the RS flip-flop 13 to the initial state.

Next, a second embodiment of the present invention will be described. 2 is a diagram showing an individual calling device having a dial sound output function, in which another configuration is added to the configuration of FIG. 1, and the configuration of other devices not shown here is the same as the circuit of FIG. is there.
