Abstract

PROBLEM TO BE SOLVED: To protect privacy of a possessor in the case of voice output of a memory dial registered in a portable telephone set in the hand-free telephone system for a mobile body. SOLUTION: With a portable telephone set 100 set to a cradle 200, a microcomputer 22 in the cradle reads a memory number and its telephone number stored in advance in the portable telephone set 100. The user uses a microphone 36 to enter a name of a dial destination to each memory number and stores it to a recording and reproducing circuit 26. When the user operates an operation switch 38 to select any of memory numbers, the microcomputer 22 reads aloud the memory number, the registered call destination (name) and the telephone number in voice, and in the case that the telephone number read from the portable telephone set 100 and the telephone number at registration of the name does not match with each other, reading aloud of the destination (name) in voice is inhibited. Thus, even when the portable telephone set 100 of other party is set on the cradle, its call destination is not outputted in voice.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone system, and more particularly to a system for hands-free use of a portable telephone in a mobile body such as a vehicle.

[0002]

2. Description of the Related Art In recent years, portable telephones have been spreading because of the convenience of being able to talk at various places. Against this background,
In many cases, mobile phones are used in automobiles. In this case, there is no particular problem if a person other than the driver uses the mobile phone, but it is not preferable from the viewpoint of running safety that the driver himself uses the mobile phone while running.

[0003] Therefore, there has been proposed a system using an adapter (called a "cradle") for mounting a mobile phone in order to use the mobile phone in a hands-free (or hands-free) manner. In such a system, the cradle outputs a reception signal from a mobile phone to a speaker in an automobile, and outputs a transmission signal from a remote microphone provided in the vehicle compartment or a control signal based on operation of a remote switch to the mobile phone. It is possible to send and receive voice (by hands-free) by remote control without directly operating the mobile phone.

For example, JP-A-3-9622 discloses that
There is disclosed a technology that allows a user to make a call without performing a dial operation or the like by using a hands-free terminal device.

[0005]

As described above, when the portable telephone is placed on the cradle and operated in a hands-free manner, if the destination data already stored (registered) in the portable telephone can be used hands-free. In this case, the call destination data (memory number, telephone number, and the name of the call destination) registered in the mobile phone may be read aloud by the cradle. However, a configuration in which call destination data stored (registered) in a mobile phone is sequentially read out may not always be preferable. In other words, while it is desirable that the cradle be able to handle any type of mobile phone, it is a privacy issue to read out call destination data of all mobile phones placed in the cradle unconditionally. May occur.

[0006] Specifically, for example, it is assumed that the owner of a certain portable telephone associates the name of the call destination with the memory dial registered in the portable telephone and stores it in the cradle. As a result, when transmitting, the memory dial read from the mobile phone and the specific name registered in the cradle are both read aloud by voice, so that the operability is extremely excellent. When a mobile phone is set in the cradle of the same vehicle and an attempt is made to make a call, the name of the registered call destination is read aloud, and the third party is informed of the call destination. Occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the purpose of reading out a call destination aloud only when it is truly necessary to protect privacy by reading out a call destination. It is an object of the present invention to provide a mobile telephone system.

[0008]

According to a first aspect of the present invention, there is provided a mobile telephone system provided with a mounting means (cradle) for mounting a mobile phone. Means for reading out call destination data including a call destination and a telephone number by voice; and reading out the voice only when call destination data satisfying a predetermined condition is selected from the call destination data. Control means for permitting the reading of the call destination by the means. Instead of reading aloud the call destination, for example, the name of the transmission destination uniformly, the voice read-out is executed only under predetermined conditions, that is, when it is determined that there is no problem in protecting the privacy of the mobile phone owner. It is possible to reliably prevent the caller from being known to the caller. The "call destination data" refers to data necessary for making a call, for example, a group of data including a memory number and a telephone number.

In a second aspect based on the first aspect, the placing means is a registration means for registering the call destination, and an acquisition means for acquiring call destination data stored in the mobile phone. Means, and the control means, if the call destination data having a telephone number corresponding to the telephone number at the time of call destination registration is selected from the acquired call destination data, The feature is that reading out of a document is permitted. If the phone number at the time of registering the call destination does not match the phone number obtained from the mobile phone, the mobile phone at the time of registering the call destination differs from the mobile phone at the time of reading the call destination data Therefore, by prohibiting the voice reading of the registered call destination, the privacy of the owner of the mobile phone at the time of registering the call destination is protected.

[0010]

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

<First Embodiment> FIG. 1 shows a system block diagram of the first embodiment. The mobile phone (mobile TEL) 100 and the cradle 200 are connected via a connector 10 with a multi-core cable, for example, a 16-core curl cord. The 16-core standard is a standard for a digital car telephone system, and its arrangement is specifically as follows.

Terminal number 1: Serial signal GND Terminal number 2: Transmission audio signal Terminal number 3: Transmission / reception signal GND Terminal number 4: TCH frame Terminal number 5: TCH clock Terminal number 6: Upstream serial signal Terminal number 7: Downstream serial Signal Terminal No. 8: Reserved Terminal No. 9: GND for serial signal Terminal No. 10: Received audio signal Terminal No. 11: Reserved Terminal No. 12: Portable unit operation unit control signal 1 Terminal No. 13: Portable unit operation unit control signal 2 Terminal number 14: Unit presence / absence Terminal number 15: Unit power control Terminal number 16: Reserved Of these, terminal numbers 2, 6, 12, 13, and 14 are used for signals from the cradle 200 to the mobile phone 100, and terminal numbers 7, Reference numerals 10 and 15 are used for signals from the mobile phone 100 to the cradle 200. In the cradle 200, electronic volumes 12 and 20 for increasing / decreasing a signal, and a codec I for performing analog / digital signal conversion
C14 and 18, IC1 for canceling echo
6. A microcomputer (microcomputer) 22 for controlling the operation of the cradle, a power supply circuit 24 for supplying power to the microcomputer 22, a recording / reproducing circuit 26 for recording / reproducing a call destination name, and the like. In this case, a mute control circuit 30 for muting a music signal in the event of a change, and various changeover switches SW1, SW2, SW3 are provided. In addition, the cradle 200 is connected to a vehicle-mounted device such as an audio by a cable. Specifically, the audio 32 and the speaker (S
P) 34, vehicle speed sensor 40, ACC 42 and power supply circuit 2
4 is connected to an in-vehicle battery 44 that supplies power. Further, a switch (button 4SW) 38 with a microphone (MIC) 36 is provided on the pillar on the driver's seat side,
The microcomputer 22 in the cradle 200
And a 4-core cable. Mobile phone 100 placed on cradle 200 and connected to cradle 200
Basic operations such as transmission, reception, response hold, etc. can be performed by operating the switch 38 and the microphone 36. The switch 38 in the present embodiment includes a dial switch, a hook switch, and a function switch, and a desired operation is realized by selecting a control mode of the microcomputer 22 by a combination of these switches.

The microcomputer 22 controls the operation of the cradle, and turns on the ACC switch 42 of the ignition.
Start by doing, its basic operating mode is
There are standby control, incoming call control, answer hold control, telephone number reading control, talking control, setting mode control, and outgoing control. Hereinafter, these controls will be briefly described.

<Standby Control> This is a normal standby state, in which SW1 is set to ON, SW2 is set to OFF, and SW3 is set to the portable telephone (TEL) side. When the user rotates the dial of the switch 38, the mode shifts to the voice reading control of the memory dial, when the hook switch is short-pressed, the mode shifts to the outgoing control, when the function switch is long-pressed, the mode shifts to the mode setting control, and when the incoming call is received, the incoming call is received The control is shifted to the control. If the hook switch is pressed during the incoming call, the control is shifted to the talking control.

<Speech-to-speech control> In this mode, the mode is shifted by rotating the dial of the switch 38 during standby, in which the telephone numbers of the memory dial stored in the mobile phone 100 are sequentially read out and output as voice. At this time, SW1 is turned off and SW2 is turned on, and the sound from the recording / reproducing circuit 26 is output from the speaker 34, and the microcomputer 22 drives the mute control circuit 30 to mute the audio 32 and read the sound read out by the user. Make it easier to hear. As items to read out,
A memory dial number, a registered name (call destination) and a telephone number. Specifically, if the dial is turned one turn to the right, the sound is output as "1, Watanabe, 0313234567", and if the dial is turned one more turn to the right, the sound is output as "2, Suzuki, 0332345678". You. The call destination is, for example, when the user operates the dial switch while the vehicle is stopped and operates the mobile phone 1.
By reading out the memory dial registered in 00 and operating the function switch within a certain time after outputting the memory dial voice, SW3 can be set to the microphone 36 side and registered in the recording / reproducing circuit 26. However, even if the call destination is registered, in the present embodiment, from the viewpoint of privacy protection, the call destination is permitted to read aloud only when a predetermined condition is satisfied, and the details will be described later.

<Outgoing call control> The voice reading of the memory dial is performed, and the user selects one of them to make a call. During the voice reading or within a fixed time after the reading is completed, the user attaches to the switch 38. When the user presses the hook switch for a short time, the mode shifts to the calling mode, and a call is made to the selected telephone number. <Mode setting control> The mode setting is to set a response when an incoming call is received during traveling, and there are three types: automatic answering, automatic call switching, and no setting. By pressing the function switches during standby, the above three modes are sequentially transited, SW1 is set to OFF and SW2 is set to ON, and a description of the mode is output from the recording / reproducing circuit 26 to the speaker 34 as sound. When the user operates the hook switch of the switch 38, one of the three modes is selected and set to that mode.

<Incoming call control> This is a control when there is an incoming call during standby. When the user presses the hook switch of the switch 38, the control is transferred to the hands-free communication control.
That is, the voice of the other party is output from the speaker 34, and the voice of the vehicle occupant such as the driver is sent from the attached microphone 36 of the switch 38 to the other party via the codec ICs 14 and 16 and the echo canceller IC 16. During a call, the microcomputer 22 drives the mute control circuit 30 to automatically mute the audio 32, and facilitates the call even if the driver or the like is listening to music or the like. When the user short-presses the function switch instead of the hook switch, the system shifts to a response hold. In this response hold control, a response hold sound is output. Then, when the user short-presses the hook switch again while the answer is on hold, the hold is released and the operation shifts to the above-described call.

On the other hand, if the user does not operate the hook switch or the function switch for a predetermined time (for example, 5 seconds) during an incoming call, the mode shifts to the mode set by the mode setting control. In other words, when the automatic answering mode is set, the microcomputer 22 outputs a message such as "I am currently driving and cannot answer the phone. I will call you again later." In this case, if the telephone number of the other party has been received, it is possible to output "Please wait for the call" following this message, and the telephone number of the other party has not been received. In such a case, it is also possible to output, for example, "Please input that telephone number with a push tone" and store the receiving number of the other party in the memory. After outputting these messages, the control of shutting down the mobile phone 100 is executed. When the automatic call switching mode is set, when the vehicle is determined to be running based on a signal from the vehicle speed sensor 40 or when the shift lever is set to the D range, the hand-free communication state is set. Otherwise, the process shifts to a user operation waiting state. It should be noted that, even when “no setting” is selected in the mode setting control, the state of waiting for the user's operation is maintained after the incoming call.

As described above, the microcomputer executes various controls by operating the switch 38. One of the features of the present embodiment is the voice reading of the memory dial in the transmission control. That is, the cradle 200 has the mobile phone 10
The memory number and telephone number read from 0 and the call destination (name) registered by the user are supplied as call destination data, but only when a predetermined condition is satisfied, all three data are read aloud. If the user is informed and the predetermined condition is not satisfied, only the memory number and the telephone number are read out by voice, and the call destination is not read out. Hereinafter, this point will be described in detail.

FIG. 2 is a flow chart showing a process for registering a call destination (name) and a process for reading out a voice from a memory dial according to the present embodiment. First, it is determined whether or not a memory number different from the current memory number has been selected by operating the dial switch of the switch 38, that is, whether or not the dial switch has been rotated from the current state (S101). If the user does not operate the dial switch, it is determined whether or not the call operation has been performed next, that is, whether or not the user has operated the hook switch (S102). When neither the dial switch nor the hook switch is operated, as described above, the memory number and its telephone number are simply stored in the mobile phone 100.
And is output as audio. Next, it is determined whether or not the name registration operation has been performed, that is, whether or not the function switch has been operated within a predetermined time (for example, within 2 seconds) after outputting the voice of the memory number and the telephone number (S103). When the function switch is operated, it is determined that there is a name registration operation, the name is registered in correspondence with the memory number at that time, and the telephone number at this time is stored in the memory together (S10).
4). Specifically, a message prompting registration of the name “Please” is sent from the speaker, and SW3 is set to the microphone 36 side, and sound-activated recording is performed for a predetermined time (for example, 1. seconds) until a predetermined time (for example, 5 seconds) elapses. (5 seconds). When the user records a desired name in the recording / reproducing circuit 26 using the microphone 36, the CR of the telephone number of the memory dial is recorded.
The C operation result (16 bits) is stored. The registration of the call destination (name) of the memory dial is completed as described above.

Thereafter, when a certain mobile phone 100 is set in the cradle 200 and the user operates the dial switch while waiting (YES in S101), the microcomputer 22 stores the memory number of the memory number registered in advance in the set mobile phone 100. The memory number corresponding to the operation of the dial switch (including the telephone number data registered with the number) is read out (S105). More specifically, when the dial switch is rotated clockwise by a predetermined amount, memory number 1 is read, and when the dial switch is further rotated clockwise, memory number 2 is read. Of course, the mobile phone 10
When 0 is set in cradle 200, mobile phone 1
It is also possible to read out all the memory numbers registered in 00 at once and store them in the microcomputer 22.
In this case, the processing of S105 becomes unnecessary. After reading the corresponding memory number, it is determined whether or not the name of the call destination is registered in the selected memory number (S10).
6) If not registered, the microcomputer 22 outputs only the memory number and the telephone number by voice. In particular,
"It is 1,033123567". On the other hand, when the name is registered, it is determined whether a predetermined condition is satisfied (S108). The predetermined condition is whether or not the telephone number of the memory number selected this time matches the telephone number at the time of registering the name (call destination) to this memory number. Specifically, the name is registered. The CRC code of the phone number stored in the microcomputer and the mobile phone 1
Whether the CRC codes of the telephone numbers read from 00 match. If it is determined that they match, that is, if the phone number read from the mobile phone 100 this time matches the phone number for which the name has been registered, all of the memory number, name, and phone number are output as voice. If the names do not match (S109), only the memory number and the telephone number are output as voice and the name is not read out as voice (S109).
107). After the voice reading is completed, when the user operates the hook switch to make a call, the process proceeds to the above-described call control (YES in S102).

As described above, since the call destination is read aloud only when the telephone number at the time of registering the name of the call destination and the telephone number read from the mobile phone 100 match, for example, the third party can read the mobile phone. 100 to cradle 20
Even if the dial switch is set to 0 and the dial switch is operated, only the memory dial registered in the mobile phone is output as voice, and the call destination registered in the cradle 200 is not output as voice so that privacy is protected. Will be. In S109, either the reading of the telephone number or the reading of the name may not be appropriately performed.

<Second Embodiment> FIG. 3 shows a flowchart of a process of registering a call destination (name) of the microcomputer 22 and a process of reading out a voice from a memory dial in the present embodiment. The basic configuration of the system and the basic control operation of the microcomputer are the same as in the first embodiment.

First, it is determined whether or not a memory number different from the current memory number has been selected by operating the dial switch of the switch 38, that is, whether or not the dial switch has been rotated from the current state (S201). If the user does not operate the dial switch, it is determined whether or not the call operation has been performed next, that is, whether or not the user has operated the hook switch (S202). When neither the dial switch nor the hook switch is operated, it is determined whether or not further name registration operation has been performed, that is, whether or not the function switch has been operated within a predetermined time (for example, within 2 seconds) after outputting the voice of the memory number and the telephone number. A determination is made (S203). When the function switch is operated, it is determined that there is a name registration operation, the name is registered in correspondence with the memory number at that time, and the telephone number at this time is also stored in the memory (S204). Specifically, as in the first embodiment, "please" from the speaker.
A message prompting registration of the name is sent, SW3 is set to the microphone 36 side, and sound-activated recording is performed for a predetermined time (for example, 1.5 seconds) until a predetermined time (for example, 5 seconds) elapses. When the user records a desired name in the recording / reproducing circuit 26 using the microphone 36, the CRC calculation result (16 bits) of the telephone number of the memory dial is stored. The registration of the call destination (name) of the memory dial is completed as described above.

Thereafter, when a certain mobile phone 100 is set on the cradle 200 and the user operates the dial switch while waiting (YES in S201), the microcomputer 22 stores the memory number of the memory number registered in advance in the set mobile phone 100. The memory number corresponding to the operation of the dial switch (including the telephone number data registered with the number) is read out (S205). Also in the present embodiment, when the mobile phone 100 is set in the cradle 200, all the memory numbers registered in the mobile phone 100 can be collectively read and stored in the microcomputer 22. In this case, the process of S205 is not required. And whether or not a predetermined condition is satisfied,
Specifically, it is determined whether or not the telephone number selected by the dial switch this time is the same as the telephone number stored when the name was registered (S206). If there is not the same memory number, it means that when the name (call destination) is registered, the mobile phone 100 has registration contents different from those of the mobile phone 100 set in the cradle 200. And only the telephone number are output by voice (S207), and if there is the same one, all of the selected memory number, name, and telephone number are read out by voice (S207).
208). Then, when the user operates the hook switch after the completion of the voice reading, a call is made (S20).
2 is YES).

As described above, in this embodiment, the telephone number (actually, the CRC calculation result) selected as the telephone number (actually, the CRC calculation result) when the name (call destination) is registered as the predetermined condition. The call destination is read aloud only when there is a match with the CRC operation result), so the mobile phone 10 set in the cradle 200 when the call destination is registered
0 and cradle 2 when dialing is selected to place a call
When the mobile phone 100 is different from the mobile phone 100 set to 00, the call destination registered in the cradle 200 is not read out and the privacy is surely protected.

<Third Embodiment> FIG. 4 is a flow chart showing a process of registering a call destination (name) of the microcomputer 22 and a process of reading out a voice from a memory dial in the present embodiment. The basic configuration of the system and the basic control operation of the microcomputer are the same as in the first embodiment.

In this embodiment, first, the microcomputer 22 reads out the telephone number of the own station of the portable telephone 100 (the telephone number of the portable telephone itself) connected to the cradle 200 and stores it in the memory (S301). Then, it is determined whether or not a memory number different from the current memory number has been selected by operating the dial switch of the switch 38, that is, whether or not the dial switch has been rotated from the current state (S302). If the user does not operate the dial switch, it is determined whether or not the call operation has been performed next, that is, whether or not the user has operated the hook switch (S303). When neither the dial switch nor the hook switch is operated, it is determined whether or not further name registration operation has been performed, that is, whether or not the function switch has been operated within a predetermined time (for example, within 2 seconds) after outputting the voice of the memory number and the telephone number. A determination is made (S304).
When the function switch is operated, it is determined whether or not the telephone number of the own station of the mobile phone 100 stored when the name was previously registered in the memory number matches the telephone number of the own station read this time. (S305). If they match, the previous mobile phone 100 and the current mobile phone 1
Since 00 is the same, there is no problem even if a new call destination (name) is registered or rewritten. Therefore, the name is registered in correspondence with the selected memory number, and the telephone number of the own station is also stored in the memory (S306). ). Although the telephone numbers corresponding to the memory numbers are stored in the first and second embodiments described above, it should be noted that the telephone numbers of the mobile phone 100 itself are stored in the present embodiment. On the other hand, if it is determined in S305 that the telephone numbers do not match, the mobile phone 100 in which the call destination (name) is registered last time and the current cradle 20
Since the mobile phone 100 is different from the mobile phone 100 set to 0, a message "cannot be registered" is output as a voice to prohibit registration of the call destination (S307). The registration of the call destination (name) is completed as described above.

Thereafter, if the user operates the dial switch during standby (YES in S302), the microcomputer 2
2 reads out a memory number (including telephone number data registered with the number) corresponding to the operation of the dial switch from among the memory numbers registered in advance in the mobile phone 100 (S308). In this embodiment,
When the mobile phone 100 is set in the cradle 200, all the memory numbers registered in the mobile phone 100 can be collectively read and stored in the microcomputer 22. In this case, the process of S308 is It becomes unnecessary. Then, it is determined whether or not the name is registered in the selected memory number (S309). If not, the memory number and the telephone number are output as voice (S31).
0). When the name is registered, it is further determined whether or not a predetermined condition is satisfied. Specifically, the predetermined condition is whether or not the telephone number of the own station stored when the name is registered in the memory number matches the telephone number of the own station read this time (S311). When the predetermined condition is not satisfied, it means that a telephone set different from the mobile telephone 100 at the time of registering the name is set.
Even if the name corresponding to the memory number is registered in the cradle 200, only the memory number and the telephone number are output as voice (S310). On the other hand, if the predetermined condition is satisfied, all of the memory number, name, and telephone number are read aloud (S312).

As described above, in the present embodiment, the reading out of the call destination (name) is prohibited by skillfully using the telephone number data of the mobile phone 100 itself.
, The privacy of the owner of the mobile phone 100 can be reliably protected.

Although the present embodiment has been described using a car phone as an example, it is needless to say that the present invention can be applied to any other mobile object.

[0032]

As described above, according to the present invention, the call destination, that is, the name and telephone number of the call destination are not read aloud by voice, but the call destination registered in advance only when a predetermined condition is satisfied. , The privacy of the owner of the mobile phone can be protected without impairing the versatility of the cradle as the mounting means, and the reliability of the mobile telephone system can be improved.
