Abstract

PROBLEM TO BE SOLVED: To eliminate the need of plural time telephone number registration by making a master unit and a slave unit respectively and successively compare the contents of the telephone books of each other and performing control so as to delete the data when the same data as a communicating party are present in the telephone book and add them when they are not present. SOLUTION: When the data for one item are transferred from the master unit 7 to the slave unit 18, the slave unit 18 checks a field and confirms whether or not they are the data whose transfer is permitted. In the case that the transfer is not permitted, the transmission request of the next data is outputted to the master unit 7. When they are the data whose transfer is permitted, they are successively compared with telephone numbers recorded in the telephone book of the slave unit 18, and when the same telephone number is present, the entire item is delete and the next data are requested to the master unit 7. When the pertinent telephone number is not present, it is additionally registered to the telephone book of the slave unit 18. In such a manner, the data present in the telephone book of the master unit 7 but not present in the telephone book of the slave unit 18 are additionally registered to the telephone book of the slave unit 18.

2. Description of the Related Art A conventional telephone, particularly a communication device such as a cordless telephone (including a PHS) having a master unit and a slave unit, uses a telephone number as a means for searching for a target party from a large number of telephone numbers. A telephone directory function that stores a telephone number corresponding to an abbreviated number or a character code facilitates dialing operation. For example, Japanese Unexamined Patent Publication
As shown in JP-A-130203, the user records the number and name of the other party in the recording means in advance, and when communicating with the other party, inputs the number of the first few digits that are memorized. Means, and the comparison means compares the number with each of the destinations recorded in the recording means. If there is a match, the number and name of the destination are displayed on the display means, and communication is performed. When the other party to be performed is found, a call can be made to communicate with the other party.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of a base unit of a radio telephone apparatus according to the present invention, wherein 1 is an antenna, 2 is
Is the radio section, 3 is the modem section, 4 is the channel codec section,
5 is a voice codec unit, 6 is a telephone circuit unit, 7 is a base unit of a wireless telephone device, 8 is a handset, 9 is a public line, 10 is a CPU, 11 is a memory, 12 is a key and display unit, 16
Is a detecting means, and 17 is a connecting means.

The antenna 1 and the handset 8 are shown separately from the base unit 7 of the wireless telephone unit, but this is for the sake of easy explanation of the operation. One component.

First, a base station (not shown) or a handset 1
The radio signal transmitted from the antenna 8 is supplied to the radio unit 2 as a reception signal by the antenna 1, subjected to frequency conversion and band limitation, and then demodulated by the modem unit 3. The demodulated data is subjected to processing such as interleaving and error correction in a channel codec unit 4 and further converted to an audio signal in an audio codec unit 5, selected by a telephone circuit unit 6 and reproduced from a speaker of a handset 8. .

The voice input from the microphone of the handset 8 is selected by the telephone circuit unit 6 and then converted from a voice signal into digital data. The channel codec unit 4 adds codes and rearranges data. After digital modulation is performed by the modem unit 3, the frequency is converted by the radio unit 2 and transmitted as a radio signal from the antenna 1.

The telephone circuit section 6 switches the communication path and is connected to the public line 9 to perform a calling operation, an incoming call detection, and an incoming call answering operation.

CPU 10 controls base unit 7 of the radio telephone device in accordance with a program stored in memory 11. The memory 11 includes a ROM and a RAM. The ROM stores a control program, a constant table, and the like. The RAM is used for storing telephone directory data, and is used as a buffer in the data processing process of the channel codec unit 4 and the CPU 10.

Therefore, the telephone directory function for storing and retrieving a telephone number for a certain ID is realized by a combination of the CPU 10 and the memory 11, but a memory dedicated to the telephone directory function may be provided.

Here, even if the memory 11 is built in the CPU 10, the same effect is obtained.

The key and display unit 12 displays the input result at the same time as the user inputs various data, and displays data derived by key input, for example, a search result of a telephone number.

The connection detecting means 16 detects that the slave unit 18 has been connected, and thereby notifies the CPU 10 that data can be transmitted and received between the master unit 7 and the slave unit 18.

The connection means 17 electrically connects the master unit 7 and the slave unit 18 to transmit and receive data, and uses a serial interface such as an RS232C interface in consideration of the number of data lines. However, the connection means 17
If the connection can be detected by using the above, the connection detecting means 16 may be included in the connecting means 17.

Next, FIG. 2 shows a block diagram of the slave unit 18 of the wireless telephone device.

The difference between the wireless telephone apparatus and the base unit 7 in FIG. 1 is that the handset 18 does not need to be directly connected to the public line 9 and thus does not require the telephone circuit unit 6, but the control method is different. The blocks are the same as those of the base unit 7, but the programs stored in the memory 11
8 different.

As shown in FIG. 2, the base unit 7 of the wireless telephone device
In the same manner as described above, a connection detection unit 16 and a connection unit 17 for transmitting and receiving data are provided, and data in the telephone directory can be transmitted and received.

FIGS. 3 and 4 show another embodiment of the base unit 7 and the handset 18 of the wireless telephone apparatus.

The base unit 7 and the handset 18 of the wireless telephone device have an infrared communication unit 13 as a transfer unit for telephone directory data. The infrared communication means 13 transmits and receives data using infrared light.

FIG. 5 shows an embodiment of the infrared data communication means 13.

The visible light cut filter 134 removes visible light from incoming and outgoing light. The light receiving / emitting circuit 135 includes a light emitting diode (not shown) that emits infrared rays, a driving circuit (not shown), a photodiode (not shown) that receives infrared rays, and an amplifier circuit (not shown). The modulation / demodulation circuit 136 includes a modulation circuit (not shown) and a demodulation circuit (not shown). The modulation circuit is a serial-parallel conversion circuit 13.
7 is converted into an emission pattern of an infrared light emitting diode. The demodulation circuit performs the reverse process of the modulation circuit. That is, the received infrared pattern is converted into a signal corresponding to the serial-parallel conversion circuit. The serial-parallel conversion circuit 137 is a circuit for converting parallel data on the data bus into serial data.

Next, the operation of updating the telephone directory data will be described with reference to the flowchart shown in FIG. Although this flowchart shows a case where data is transferred from the master unit 7 to the slave unit 18, the operation for transferring data from the slave unit 18 to the master unit 7 when the master unit 7 and the slave unit 18 are exchanged will be described. The data transmission / reception method will be described in accordance with the connection method shown in FIGS. 1 and 2, but the operation of updating the telephone directory data is the same regardless of the connection method.

First, the telephone book data update mode is set by the key and the display unit 12, and at the same time, the number N of data to be transferred is initialized. (Step S1) The connection detection unit 16 detects that the slave unit 18 is connected. (Step S2) If the slave unit 18 is not connected, an error message is displayed on the key and the display unit 12 to inform the user that the slave unit 18 is not connected, and the telephone book data update mode is canceled or the slave unit is canceled. After confirming the connection at 18, the user is prompted to continue. (Step S
5) When data transfer becomes possible, add 1 to the number N of data and wait for the data of item 1 to be transferred. (Step S
3) Here, one embodiment of the data structure is shown in FIG.

In FIG. 7, F1 (field 1) indicates an item number. F2 (field 2) indicates an identification code for the telephone number, for example, a person name or a company name is input. F3
(Field 3) inputs a telephone number. F4 (field 4) is used to input whether transfer is permitted. Here, for example, the telephone number of item 1 Suzuki Ichiro is 045 123 4567, which indicates that the transfer is permitted.

When one item of data is transferred from the master unit 7 to the slave unit 18 (step S4), the slave unit 18
By examining (field 4), it is confirmed whether or not the data is permitted to be transferred. Here, if the transfer is not permitted as shown in item 2 of FIG. 7, a request for transmitting the next data is output to the master unit 7. (Step S10) If the data is permitted to be transferred, it is sequentially compared with the telephone number recorded in the telephone directory of the slave unit 18, and if there is the same telephone number, the entire item is discarded, and the parent item is discarded. The next data request is made to the device 7. (Step S6) If there is no corresponding telephone number, additional registration is performed in the telephone directory of the slave unit 18. (Step S7) If the data in F1 (field 1) is a predetermined code indicating the end of the data, there is no data to be received, and the operation of updating the telephone directory data ends. (Step S
8) (Step S9) If it is other data, the parent machine 7
Request for the next data, and return to the processing of step 2 again.

By the above operation, data which exists in the telephone directory of the base unit 7 but does not exist in the telephone directory of the child unit
8 can be additionally registered in the telephone directory. Therefore, next, if the same transmission / reception operation is performed by reversing the operations of the parent device 7 and the child device 18, data that exists in the telephone directory of the child device 18 but does not exist in the telephone directory of the parent device 7 is transferred to the child device 18. It can be additionally registered in the phone book. However, when data is transferred from the master unit to the slave unit, the matched item numbers are stored, and the transfer from the slave unit to the master unit is registered only in the slave unit except for the matched item numbers. Unnecessary data transfer can be prevented by transferring only data that has not been transferred.

Here, F4 (field 4) in FIG. 7 is used to separate, for example, data that is desired to be shared and data that is not desired to be shared. However, there is no necessity in a case where there is no particular need to keep concealment, and similarly, in step S1 in FIG.
The processing of 0 becomes unnecessary.

Data transfer is also performed when registration is not permitted, but when registration is not permitted, for example, F1
If a code indicating non-permitted data is determined in advance in (field 1), useless data transfer can be reduced, and transfer time can be saved.

[0032]

When the parent device and the child device each have a telephone directory function, a similar registration operation is required again. In particular, when there are a plurality of slave units, such as in a business office, it is necessary to repeat the registration operation by the number of slave units, which is inconvenient.

According to the present invention, if the telephone number is registered once in either the master unit or the slave unit, the data of the master unit and the slave unit can be transferred to each other, so that there is no need to register the telephone number a plurality of times. .
