Description

  The present invention relates to a hands-free call device and a control method thereof.

Conventionally, in a hands-free call device, phone book data registered in association with the name of the calling party and a telephone number is stored in advance in the storage unit, and when the user calls the phone book data when making a call, There is known one in which a list of outgoing call destinations registered in advance in phone book data is displayed on a display unit. In this type of hands-free call device, when a user makes a call, it is determined whether the user is working based on the current time, and the call registered in the phone book data is determined according to the determination result. There has been proposed a technique that makes it easier for a user to select a call partner by sorting the opponents in the order of high possibility of sending by the user and displaying the sorting results as a list on the display unit (see, for example, Patent Document 1). ).
Japanese Patent Laid-Open No. 10-23135

However, when the number of registrations in the phone book data increases, even if the hands-free call device is sorted and displayed as a list, the number of destinations displayed in the list increases. There is a problem that it becomes difficult to find a desired caller.
The present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide a hands-free call device and a control method capable of easily finding a desired call partner when a user tries to make a call. And

  In order to achieve the above-mentioned object, the present invention picks up a transmitted voice of a user of a mobile phone and transmits it to the mobile phone, and also receives a received voice from the mobile phone and emits it. The transmission history recording means for associating and recording the calling party registered in the phone book data stored in the mobile phone and the transmission date and time to the calling party, recording by the calling history recording means, and , Based on the current date and time, searching for a caller who is likely to be selected as a callee, obtaining a corresponding caller, and display means for displaying the searched caller It is characterized by that.

  Further, the present invention is the above invention, wherein the search means is a history transmitted in the past, a history transmitted in a predetermined time zone including the current time, and a history transmitted on the same day of the week as the current day of the week. The narrowing search is sequentially executed in this order, and when there is no corresponding transmission partner, the transmission partner corresponding to the immediately preceding search is acquired as a transmission partner having a high possibility as the transmission destination.

  In the above invention, the present invention further comprises storage means for storing a user's work day, wherein the transmission history means records in association with the transmission date and time whether or not it is a work day, and the search means Further, it is characterized in that a caller who is highly likely to be selected as a callee is searched based on the record by the call history recording means and whether it is the current date and work day.

  Further, the present invention is characterized in that, in the above-mentioned invention, when the record by the call history recording means is empty, a call partner registered in the telephone directory data is displayed.

  In order to achieve the above-mentioned object, the present invention picks up a transmitted voice of a user of a mobile phone and transmits it to the mobile phone, and also receives a received voice from the mobile phone and emits it. In the control method of the telephone device, based on the data recorded in association with the calling party registered in the phone book data stored in the mobile phone and the calling date and time to the calling party, and the current date and time In this case, a search is made for a caller who is highly likely to be selected as a callee, and the corresponding caller is displayed in a list as a telephone directory.

  According to the present invention, since a caller who is highly likely to be selected as a callee is displayed based on the record by the call history recording means and the current date and time, many callers are registered in the phone book. Even so, it is possible to easily find a desired caller.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram schematically illustrating a configuration of a hands-free call system 1 including a hands-free call device 10 according to the present embodiment. As shown in this figure, the hands-free call system 1 includes a hands-free call device 10 mounted on a vehicle 50 and a mobile phone 20 brought into the vehicle 50 by a user. The mobile phones 20 are configured to be capable of short-range wireless communication compliant with the Bluetooth (registered trademark) standard. The mobile phone 20 performs call communication with another mobile phone 40 or a fixed phone (not shown) via the mobile communication network 30, and includes a speaker, a microphone, an antenna for call communication, and the like.
The hands-free call device 10 enables a user such as a driver or a passenger to talk to another mobile phone 40 or a fixed phone (not shown) without holding the mobile phone 20 in the vehicle 50. It is a device that transmits the voice transmitted from the user to the mobile phone 20, and receives the voice received from the other mobile phone 40 or the fixed phone from the mobile phone 20 and emits it into the vehicle 50.

FIG. 2 is a block diagram showing a functional configuration of the hands-free call device 10. In this figure, the control part 100 controls each part centrally.
The short-range wireless communication unit 101 has a wireless communication device (not shown) that performs short-range wireless communication with the mobile phone 20 and receives a received voice received by the mobile phone 20 from another mobile phone 40 or a fixed phone. Then, the data is output to the control unit 100, and the voice to be transmitted to another mobile phone 40 or a fixed phone is transmitted to the mobile phone 20.
The sound emitting unit 102 emits sound into the vehicle interior according to the sound signal from the control unit 100, and the sound receiving unit 103 picks up the transmitted voice emitted by the user and converts it into a sound signal. It outputs to the control part 100 later.
When the received voice is received from the short-range wireless communication unit 101, the control unit 100 generates a voice output signal based on the received voice and outputs the voice output signal to the sound emitting unit 102 to send the received voice from the sound emitting unit 102 to the vehicle interior. When the sound is emitted and the transmitted voice is acquired from the sound receiving unit 103, the transmitted voice is transmitted to the mobile phone 20 via the short-range wireless communication unit 101, and the mobile phone 20 transmits another mobile phone 40 or Transmit the transmission signal to the landline.

The display unit 104 displays various types of information under the control of the control unit 100. The display unit 104 displays a list of outgoing call destinations registered in the phone book data 124 described later as a phone book. Is done.
The operation unit 105 outputs a user instruction input to the control unit 100 such as an instruction to display the telephone directory. The operation unit 105 is provided with a YES button 115, a NO button 116, and a CANCEL button 117 for operating the telephone directory.
The engine operation detection unit 106 detects the start and stop of the engine of the vehicle 50 and outputs the detected result to the control unit 100. Specifically, the engine operation detection unit 106 starts and starts the engine based on on / off of the accessory power supply. Detect.
The timer unit 107 has an oscillator that generates a signal of 1 Hz, a second counter that counts time based on the signal of the oscillator, a minute counter and an hour counter, and a date count that counts a date based on the time, The time and date are counted and output to the control unit 100.
The storage unit 108 stores various programs and data executed by the control unit 100. Besides these, the storage unit 108 includes calendar data 120, engine operation record data 121, work day data 122, Transmission history data 123 and telephone directory data 124 are further stored.

The calendar data 120 is data indicating a correspondence between a date and a day of the week and a holiday.
The engine operation record data 121 is data that is collected in order to identify the user's working day based on the engine operation status of the vehicle 50, and the engine operation record data 121 indicates that the user selects the engine of the vehicle 50. Each time the engine is started and stopped, the control unit 100 records the time, day of the week, and whether or not the day falls on a national holiday.
The work day data 122 indicates the day of the week estimated to be the day of the week on which the user works based on the engine operation record data 121.

  More specifically, when engine start or stop is detected by the engine operation detection unit 106, the control unit 100 acquires the current time and date from the time measuring unit 107, and the day of the week and the date are displayed. Whether it falls on a holiday is determined based on the calendar data 120, and one record including a flag indicating whether the time, day of the week, and whether the day falls on a holiday is generated and stored in the engine operation record data 121. Record. Then, the control unit 100 extracts, as a work day, a day of the week when the engine is started in a predetermined time period based on each record of the engine operation record data 121 for each predetermined number of days. To record.

The transmission history data 123 is data for recording a history of transmissions made by the user in the past. As shown in FIG. 3, the transmission partner, the transmission time, the transmission date, the day of the week, the holiday flag, and the work day flag transmitted by the user. Are recorded in association with each other. The holiday flag indicates whether or not the transmission date corresponds to a holiday, and the work day flag indicates whether or not the transmission date corresponds to a work day.
A record is added to the transmission history data 123 by the control unit 100 every time a user makes a call using the handsfree call device 10. That is, when a call is made, the control unit 100 generates one record including a call partner, a call date, a call time, a day of week, a holiday flag, and a work day flag in the same manner as the engine operation record data 121 described above. And added to the transmission history data 123. As described above, since the transmission history data 123 indicates a history transmitted by the user, in this embodiment, the transmission history data 123 is also used as a so-called transmission history.

  The phone book data 124 is data in which the name and phone number of the calling party are recorded. As shown in FIG. 4, in one record of the phone book data 124, a search that is referred to when displaying the calling party (name and phone number) and the phone book based on the phone book data 124 on the display unit 104. Index information 130 is included. The information of the calling party in each record is obtained from the information of the calling party registered in the phone book data stored in the user's mobile phone 20. The search index information 130 is for classifying a caller based on the date and time, and information such as a day of the week, a holiday, and a work day specified from the date. A time parameter 140, a day of week parameter 141, a holiday parameter 142 and a work day parameter 143.

The time parameter 140 indicates a time (time zone) at which a call is likely to be made to a call destination, and a day of week parameter 141 indicates a day of the week at which a call is likely to be made to the call destination. is there. The holiday parameter 142 is a flag indicating whether or not a call to the call destination is made on a public holiday, and the work day parameter 143 is whether or not a call to the call destination is made on a work day. It is a flag which shows.
These time parameter 140, day of week parameter 141, public holiday parameter 142, and work day parameter 143 are generated for each caller based on the statistics of the record of the call history data 123.

Specifically, the control unit 100 sets the number of calls for each time zone, the number of calls for each day of the week, the number of calls on a public holiday, and the number of calls on a work day for each caller registered in the phone book data 124. Count based on the transmission history data 123.
Then, the control unit 100 sets a time zone in which the outgoing times to the caller are concentrated (a time zone in which the number of outgoing calls is larger than other time zones) in the time parameter 140, and makes a call to the caller. The day of the week on which the number of calls is concentrated (the day with the highest number of outgoing calls) is set in the day of week parameter 141. At this time, if the transmission time and day of the week are distributed almost uniformly over all time periods and all days of the week, or if the number of transmissions is small, the control unit 100 specifies the time period and day of the week when the transmission is concentrated. First, information indicating that the time parameter 140 and the day of week parameter 141 are not set is set (“0” in the illustrated example).

  In addition, when the outgoing calls to the caller are concentrated on holidays rather than on weekdays, the control unit 100 sets a flag (1 in the illustrated example) indicating that to the holiday parameter 142, and sends the caller. When outgoing calls are concentrated on work days, a flag (“1” in the illustrated example) indicating that fact is set in the work day parameter 143. At this time, as with the time parameter 140 and the day of week parameter 141, when the difference in the number of calls between weekdays and holidays is small, or when the difference in the number of calls between work days and work days is small, When the number of times itself is small, information (“0”) indicating that the number is not set in the holiday parameter 142 and the work day parameter 143 is set.

By registering the search index information 130 as described above in the phone book data 124 in association with each caller, each date item including a date, a day of the week, a public holiday, and a work day specified from the date is displayed. The calling party is classified.
When the display of the phone book is instructed, the corresponding caller is extracted from the phone book data 124 using the current time, date, whether the date is a holiday, and whether it is a work day as a search key. The list of the callers is displayed as a phone book. Hereinafter, such a telephone directory display process will be described with reference to FIG.

FIG. 5 is a flowchart of the phone book display process. In this phone book display process, in order to display a smaller number of callers as a phone book, a search is made by narrowing down the corresponding callers in order of outgoing call history, current time, today's date (day of week, holiday), and work day. When the corresponding caller becomes zero, a list of callers narrowed down immediately before is displayed on the display unit 104 as a phone book.
Specifically, as shown in FIG. 5, when the display of the phone book is instructed by the user, the control unit 100 first refers to the call history data 123 and records records sent by the user in the past. It is determined whether there is a history of transmission (step S1). If the user has never made a call using the hands-free call device 10, no call record is registered in the call history data 123 (empty state). The time parameter 140, day of week parameter 141, public holiday parameter 142, and working day parameter 143 are all not set (“0”) for all outgoing parties in the data 124, and even if a narrow search is performed There is no outgoing call partner. Therefore, if there is no record in the outgoing history data 123 (step S1: NO), the control unit 100 displays a list of all outgoing parties registered in the phone book data 124 on the display unit 104 as a phone book. (Step S2), the process is terminated.

  On the other hand, when there is a record in the transmission history data 123 (step S1: NO), the control unit 100 acquires the current time from the time measuring unit 107, and uses the time zone including the current time as a search key, and the time zone is a time parameter. A search is made for the calling party set to 140 (step S3). Then, the control unit 100 determines whether or not there is a corresponding transmission partner (step S4). If there is no corresponding transmission partner (step S4: NO), the control unit 100 selects the transmission partner registered in the transmission history data 123. A list is displayed on the display unit 104 as a telephone directory (step S5). If there is a corresponding caller (step S4: YES), the search is further refined according to the following conditions.

  That is, the control unit 100 acquires today's date from the time measuring unit 107, and determines whether or not the date corresponds to a holiday based on the calendar data 120 (step S6). When today is a public holiday (step S6: YES), the control unit 100 narrows down the outgoing call partner whose holiday parameter 142 is set to “1” (step S7), and whether there is a corresponding outgoing call partner. Is determined (step S8). When there is no corresponding caller (step S8: NO), the control unit 100 displays a list of callers whose time zone including the current time is set in the time parameter 140 on the display unit 104 as a telephone directory (step S104). S9) If there is a corresponding caller (step S9: YES), a list of the callers is displayed on the display unit 104 as a telephone directory (step S10), and the process ends.

  If today is not a holiday (step S6: NO), the control unit 100 identifies today's day of the week based on the calendar data 120, and the day of the week is set in the day of week parameter 141 using that day of the week as a search key. Narrow down the caller (step S11). Next, the control unit 100 determines whether or not there is a corresponding transmission partner (step S12). If there is no corresponding transmission partner (step S12: NO), the control unit 100 displays a phone book based on the previous narrow search result. Accordingly, the processing procedure is advanced to step S9, a list of callers whose time zone including the current time is set in the time parameter 140 is displayed on the display unit 104 as a telephone directory (step S9), and the process is terminated. .

When there is a caller corresponding to the search in step S12 (step S12: YES), the control unit 100 further narrows down the caller whose “1” is set in the work day parameter 143 (step S13). ), It is determined whether there is a corresponding caller (step S14). When there is no corresponding caller (step S14: NO), the control unit 100 displays the search result of step S11, that is, a list of callers whose today day of the week is set in the day-of-week parameter 141 as a phone book. 104 is displayed (step S15), and the process is terminated.
On the other hand, if there is a corresponding caller (step S14: YES), a list of callers whose work day parameter 143 is set to “1” is displayed on the display unit 104 as a phone book (step S16). The process ends.

Through the above processing, when the user instructs display of the phone book, a narrowing search of the caller is performed in the order of the outgoing call history and the current time. Furthermore, when today is a public holiday, a narrowing search by public holiday is performed. If today is not a public holiday, a further refined search is performed in the order of the day of the week and the working day, and a list of corresponding outgoing parties is displayed as a telephone directory.
In this way, the time, day of the week, and the day when the phone book is displayed based on the transmission history such as the transmission time and day of the week that the user has transmitted in the past and whether or not the day falls on a holiday or work day. A list of callers that match the current date and time conditions (conditions) such as whether or not it falls on a day is displayed as a phone book. It is possible to include only. As a result, even if the number of destinations registered in the phone book increases, it becomes possible to easily find the destination phone number.

  Here, the corresponding caller is displayed as a telephone directory by the above-described narrowing search, but there are cases where the caller is not included in the list. Therefore, in this embodiment, after the phone book is displayed by the above phone book display process, the control unit 100 displays the displayed phone book each time the user operates the NO button 116 provided on the operation unit 105. A list of destinations corresponding to the previous narrow search is displayed from the narrow search corresponding to the list. As a result, the number of outgoing call partners displayed as a telephone book increases stepwise in accordance with the current time-series element items, so that the telephone number of the outgoing call party can be found easily and quickly with a small number of operations.

Thus, according to the present embodiment, every time a call is made to the caller registered in the phone book data 124, the call time to the caller, the day of the call, and whether the call day is a holiday. Whether or not the transmission date is a work day is recorded in the transmission history data 123, and when the display of the telephone book is instructed, the transmission is made under conditions close to the current date and time based on the transmission history data 123 It is configured to search for a caller having a history, that is, a caller who is highly likely to be selected as a callee, and display a list of applicable callers.
With this configuration, a list including the caller desired by the user is displayed, and even when a large number of callers are registered in the phone book data 124, it is possible to easily find the caller.

  Further, according to the present embodiment, the search is refined in the order of the history transmitted in the past, the history transmitted in a predetermined time zone including the current time, and the history transmitted on the same day of the week as the current day of the week. Is executed in order to display the corresponding caller as a phone book, and when there is no corresponding caller as a result of the narrow search, the caller corresponding to the previous search is displayed as the phone book. Only the callers who are more likely to be selected as callees are narrowed down and displayed, making it easier to find callers.

  It should be noted that the above-described embodiments merely show one aspect of the present invention, and it is needless to say that modifications and applications can be arbitrarily made within the scope of the present invention.
