Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each of the following embodiments, the same parts are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a schematic diagram showing an example of the hands-free system 100 of the present embodiment.

The hands-free system 100 includes a hands-free device 1 and a mobile phone 10. The hands-free device 1 and the mobile phone 10 are connected by wireless communication. The mobile phone 10 can communicate with a telephone such as another mobile phone 10 via a base station 104 via a telephone line.

The hands-free device 1 communicates and connects with the mobile phone 10. Further, the mobile phone 10 wirelessly communicates with the base station 104 via the mobile phone network. The mobile phone 10 is, for example, a smartphone and has a communication function by the Bluetooth (registered trademark) method which is a short-range wireless communication means. The mobile phone 10 may be a mobile phone of a type other than a smartphone as long as it has a communication function based on the Bluetooth method.

The hands-free device 1 connects to the mobile phone network via the mobile phone 10. Thereby, for example, the driver of the vehicle 102 can make and receive a telephone call by operating the hands-free device 1 without operating the mobile phone 10. The hands-free device 1 may be realized, for example, as a function of an in-vehicle navigation device mounted on a vehicle 102.

In this embodiment, a mode in which the hands-free device 1 is mounted on the vehicle 102 will be described as an example. The hands-free device 1 is not limited to the form mounted on the vehicle 102.

FIG. 2 is a block diagram of the hands-free system 100.

The mobile phone 10 establishes a mobile phone line with the base station 104 of the mobile phone network, and executes outgoing call processing and incoming call processing.

The call processing is a process of making a call using the telephone number that has received the input as the call destination. For example, assume that the user operates a dial key (numerical keys of "0" to "9") to input a telephone number of a call destination, and then operates a call key. In this case, the mobile phone 10 executes a transmission process of transmitting the input-accepted telephone number as the destination. The call processing enables the mobile phone 10 to make a call with another mobile phone 10 at the call destination.

The incoming call processing is a process of accepting an incoming call from another mobile phone 10. For example, the mobile phone 10 receives an incoming signal from the base station 104 in response to a call from another mobile phone 10. The mobile phone 10 receives the telephone number of another mobile phone 10 from which the caller is made as an incoming telephone number. Then, the mobile phone 10 executes an incoming call process in response to the calling mobile phone 10 by operating the earpiece key by the user. The incoming call processing enables the mobile phone 10 to make a call with another mobile phone 10 of the caller.

The mobile phone 10 changes its telephone communication state due to outgoing call processing, incoming call processing, and the like.

The telephone communication state means a communication state between the mobile phone 10 and another mobile phone 10 via a telephone line. Specifically, the telephone communication state is any one of a outgoing call state, an incoming call state, a call state, and a standby state.

The outgoing call state is a state in which the mobile phone 10 is making a call using the telephone number accepted as the call destination. The incoming call state is a state in which the mobile phone 10 is receiving an incoming call from another mobile phone 10. The call state is a state in which the mobile phone 10 and another mobile phone 10 are communicating voice via the base station 104, that is, during a call. The standby state means that the communication state via the telephone line of the mobile phone 10 is neither a outgoing state, an incoming call state, nor a call state. In other words, the standby state means a state other than the call state and waiting for an incoming call or an outgoing call.

The mobile phone 10 transitions from one of the outgoing call state, the incoming call state, the call state, and the standby state to the other telephone communication state according to the communication via the telephone line. The mobile phone 10 notifies the hands-free device 1 of the telephone communication status by HFP each time the telephone communication status changes. Therefore, the hands-free device 1 is configured to be able to specify the telephone communication state of the mobile phone 10.

The mobile phone 10 stores telephone data related to the telephone. The telephone data includes at least one of outgoing call history data, incoming call history data, missed call history data, and telephone directory data.

The outgoing call history data is data representing the outgoing call history of a telephone. More specifically, the outgoing call history data is data for one or a plurality of cases in which the correspondence between the outgoing telephone number and the outgoing date and time is set as the data for one case. The mobile phone 10 has a clock unit that measures the date and time, which is the date and time. The mobile phone 10 uses the correspondence between the outgoing telephone number and the outgoing date and time as data for one case, and stores the outgoing call history data for a plurality of cases. The calling telephone number is a telephone number received from the dial key in the outgoing call processing. The transmission date and time is the date and time measured by the clock unit during the transmission process.

The incoming call history data is data representing the incoming call history of a telephone. More specifically, the incoming call history data is data for one or a plurality of cases in which the correspondence between the incoming telephone number and the incoming date and time is set as the data for one case. The mobile phone 10 uses the correspondence between the incoming telephone number and the incoming date and time as data for one case, and stores the incoming call history data for a plurality of cases. The incoming telephone number is a telephone number received from another mobile phone 10 via the base station 104 in the incoming call processing. The incoming date and time is the date and time measured by the clock unit during the incoming call processing.

The missed call history data is data representing an incoming call history when an incoming call from another mobile phone 10 is not answered. Specifically, the missed call history data is data for one or a plurality of cases in which the correspondence between the incoming telephone number and the incoming date and time is one case. The mobile phone 10 uses the correspondence between the incoming telephone number received when the incoming call from the other mobile phone 10 is not answered and the incoming date and time as the data for one case. Then, the mobile phone 10 stores the missed call history data, which is the data for one or a plurality of cases.

The telephone directory data is data for a plurality of cases in which the correspondence between the telephone number and the registered name is the data for one case. The mobile phone 10 stores, for example, about 500 cases in the non-volatile memory in association with the telephone number input by the user and the registered name.

The telephone data may include all history data in which outgoing call history data, incoming call history data, and missed call history data are integrated. Further, in the following, when the outgoing call history data, the incoming call history data, the missed call history data, and the entire history data are collectively described, they may be simply referred to as historical data. Further, the history data may not include all the history data.

The registered name may be further included in the outgoing call history data, the incoming call history data, and the missed incoming call history data.

The mobile phone 10 determines whether or not the telephone number of the incoming telephone number received from the base station 104 is registered in the telephone directory data. When registered, the mobile phone 10 stores the registered name corresponding to the telephone number as incoming call history data in association with the telephone number and the incoming date and time. Similarly, when the mobile phone 10 does not answer an incoming call from another mobile phone 10, the registered name may be stored as missed call history data in association with the incoming telephone number and the incoming date and time. Further, the mobile phone 10 determines whether or not the telephone number of the called incoming telephone number is registered in the telephone directory data. When registered, the mobile phone 10 stores the registered name corresponding to the telephone number as outgoing call history data in association with the telephone number and the outgoing date and time.

When the mobile phone 10 receives a display request due to a user operation or the like, the mobile phone 10 displays the telephone directory data. The mobile phone 10 accepts the selection of one of the plurality of telephone numbers included in the telephone directory data, and receives the outgoing call instruction. The mobile phone 10 executes a call processing with the selected telephone number as the call destination. Therefore, the user can undoubtedly execute the outgoing call processing with a simple operation without inputting all the number keys corresponding to the numbers constituting the telephone number one by one.

The mobile phone 10 can store, for example, the latest 20 cases of outgoing call history data, incoming call history data, and missed incoming call history data. The mobile phone 10 updates these data by automatically deleting the oldest data each time the outgoing call processing, the incoming call processing, and the missed call processing are performed. The number of these data stored in the mobile phone 10 is not limited to 20.

In the present embodiment, the mobile phone 10 has a short-range wireless communication function. In the present embodiment, the mobile phone 10 performs short-range wireless communication corresponding to Bluetooth (registered trademark) as a wireless communication standard. The mobile phone 10 connects to and communicates with the hands-free device 1 by using a profile such as a hands-free profile and a phone book access profile. The hands-free profile will be referred to as HFP (Hands Free Profile) below. The phonebook access profile will be described below with reference to PBAP (PhoneBook Access Profile).

HFP is a hands-free communication protocol for performing hands-free communication, and is a profile defined by a wireless communication standard. PBAP is a data transfer protocol for transferring telephone data, and is a profile defined by a wireless communication standard. These profiles represent communication protocols defined for each function.

PBAP is an example of a data transfer protocol for performing data transfer, and is a profile defined by the Bluetooth standard. The PBAP is a profile capable of automatically transferring telephone data from the mobile phone 10 to the hands-free device 1 after the connection using the PBAP is made, without the user having to operate the mobile phone 10 at all. be. That is, the mobile phone 10 is configured to be able to automatically transfer telephone data to the hands-free device 1.

For example, the mobile phone 10 connects the PBAP immediately after establishing a communication line with the hands-free device 1, and automatically transfers the telephone data stored at that time to the hands-free device 1. As a result, when the mobile phone 10 exists within the Bluetooth communication range of the hands-free device 1, the mobile phone 10 can use the telephone data (telephone book data, outgoing call history data, incoming call history data, missed incoming call history data) in the hands-free device. Automatically transfer to 1.

Next, the hands-free device 1 will be described.

The control unit 2 controls all operations such as communication operation and data management operation of the hands-free device 1. The details of the control unit 2 will be described later.

The Bluetooth communication unit 3 is a wireless communication device that performs short-range wireless communication. In the present embodiment, the Bluetooth communication unit 3 performs short-range wireless communication corresponding to Bluetooth as a wireless communication standard. In the present embodiment, the Bluetooth communication unit 3 establishes a wireless communication line with the mobile phone 10 existing in the Bluetooth communication range, and performs communication conforming to the Bluetooth communication standard.

The Bluetooth communication unit 3 connects to the mobile phone 10 by using a profile such as HFP which is a hands-free communication protocol for performing hands-free communication and PBAP which is a data transfer protocol for transferring telephone data. And communicate.

Further, the Bluetooth communication unit 3 is configured to be capable of multi-profile connection. Therefore, the Bluetooth communication unit 3 can be connected to the mobile phone 10 at the same time by using both HFP and PBAP.

Multi-profile connections are sometimes referred to as simultaneous connections. In Bluetooth, up to seven slave communication devices can be simultaneously connected to one master communication device by time division multiplexing. That is, the communication channel can communicate with seven independent time-division channels. In this case, the simultaneous connection uses two of the seven communication channels, one of the two communication channels is used by HFP, and the other is used by PBAP. Further, the logical channel of one communication channel may be shared by HFP and PBAP and operated at the same time as in packet communication.

The operation unit 4 accepts input by the user. The operation unit 4 is composed of, for example, a touch key formed on the display unit 5, receives an operation signal representing a user's operation content, and outputs the operation signal to the control unit 2.

The display unit 5 displays the display screen based on the display signal received from the control unit 2. For example, the display unit 5 displays a display screen for accepting input of a telephone number by a user. This display screen is, for example, a screen in which dial keys corresponding to "0" to "9" are arranged.

The working memory 6 stores various data. In the present embodiment, the work memory 6 stores telephone directory data, outgoing call history data, incoming call history data, and missed incoming call history data, which are telephone data automatically transferred from the mobile phone 10. The working memory 6 can store, for example, 5 outgoing call history data, 5 incoming call history data, and 5 missed incoming call history data. The number of cases that can be stored in the working memory 6 is not limited to five. The working memory 6 is, for example, a volatile memory.

The storage memory 7 stores various data. The storage memory 7 is composed of, for example, a non-volatile memory.

The microphone 8 receives an input of voice emitted by a user when making a hands-free call using the mobile phone 10. The speaker 9 outputs the received voice of the call destination when making a hands-free call using the mobile phone 10.

The hands-free device 1 may further include various configurations necessary for navigation operation. For example, the hands-free device 1 includes a GPS (Global Positioning System), a route search unit, a map data reading unit, a VICS (registered trademark) (Vehicle Information and Communication System) information receiving unit, and a voice recognition unit. You may.

GPS is a system that detects the current position of the own vehicle. The route search unit is a system that searches for a route from the current position to the destination. The map data reading unit is a system that reads map data from a recording medium. The VICS information receiving unit is a system that receives VICS information distributed from the VICS center. The voice recognition unit is a system that recognizes the voice emitted by the user.

The hands-free device 1 is configured to supply power and stop power supply in conjunction with the on / off of the ACC (accessory power supply) switch of the vehicle 102, for example. For example, assume that the ACC switch is switched from on to off according to the user's operation. In this case, the power supply to the hands-free device 1 is stopped. When the power supply is stopped, the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data stored in the working memory 6 are deleted. On the other hand, various data such as transfer management data stored in the storage memory 7 are not erased and remain stored even after the power supply is stopped.

Next, the details of the control unit 2 will be described.

FIG. 3 is an example of a functional block diagram of the control unit 2. The control unit 2 includes a hands-free connection unit 2A, a data transfer connection processing unit 2B, a transfer control unit 2D, and a display control unit 2E.

The hands-free connection unit 2A, the data transfer connection processing unit 2B, the transfer control unit 2D, and the display control unit 2E are realized by, for example, one or a plurality of processors. For example, each of the above-mentioned parts may be realized by having a processor such as a CPU (Central Processing Unit) execute a program, that is, by software. Each of the above-mentioned parts may be realized by a processor such as a dedicated IC (Integrated Circuit), that is, hardware. Each of the above parts may be realized by using software and hardware in combination. When a plurality of processors are used, each of the plurality of processors may realize one of each of the plurality of parts, or may realize two or more of each of the plurality of parts.

The processor realizes each of the above-mentioned plurality of parts by reading and executing the program stored in the storage memory 7. Instead of storing the program in the storage memory 7, the program may be directly incorporated in the circuit of the processor. In this case, the processor realizes each of the above-mentioned plurality of parts by reading and executing the program incorporated in the circuit.

The hands-free connection unit 2A executes a hands-free connection process of wirelessly connecting to the mobile phone 10 using the HFP. The hands-free connection process is a process of establishing a wireless communication connection with the mobile phone 10 using the HFP. That is, the hands-free connection unit 2A establishes the connection of the HFP between the hands-free device 1 and the mobile phone 10.

When the HFP connection is established, the hands-free device 1 is in a state where hands-free communication via the mobile phone 10 is possible. Specifically, the hands-free connection unit 2A transmits the voice received from the microphone 8 to the mobile phone 10 via the Bluetooth communication unit 3. The mobile phone 10 transmits the voice received from the hands-free device 1 to the mobile phone 10 having the destination telephone number via the base station 104. Further, the hands-free connection unit 2A receives the voice received by the mobile phone 10 from the other mobile phone 10 via the Bluetooth communication unit 3 and outputs the voice to the speaker 9. Therefore, the hands-free device 1 enables hands-free calling. In this embodiment, the wireless communication connection using HFP may be referred to as an HFP connection or an HFP connection.

The data transfer connection processing unit 2B uses PBAP to perform wireless communication connection processing with the mobile phone 10 and data transfer processing for transferring telephone data from the mobile phone 10. The data transfer connection processing unit 2B establishes a wireless communication connection using PBAP with the mobile phone 10 via the Bluetooth communication unit 3. By establishing a wireless communication connection using PBAP, telephone data is automatically transferred from the mobile phone 10 to the hands-free device 1. The automatic transfer means that data is transferred between the hands-free device 1 and the mobile phone 10 without any operation by the user. In the following, the automatic transfer of telephone data from the hands-free device 1 to the mobile phone 10 may be referred to as acquisition of telephone data by the hands-free device 1 or transfer of telephone data. Further, in the present embodiment, the wireless communication connection using PBAP may be referred to as a PBAP connection or a PBAP connection.

When the PBAP connection is established, the data transfer connection processing unit 2B sequentially transmits each transfer request of history data such as outgoing call history data, incoming call history data, and missed incoming call history data to the mobile phone 10. The data transfer connection processing unit 2B transmits a transfer request to the mobile phone 10 under the control of the transfer control unit 2D, which will be described later.

The mobile phone 10 transfers the history data corresponding to the transfer request received from the hands-free device 1 to the mobile phone 10. Further, the data transfer connection processing unit 2B transmits a transfer request for the telephone directory data to the mobile phone 10. The mobile phone 10 transmits the telephone directory data to the mobile phone 10 in response to the transfer request received from the hands-free device 1. By these processes, the telephone data is automatically transferred from the mobile phone 10 to the hands-free device 1.

Further, the data transfer connection processing unit 2B transmits a transfer stop request to the mobile phone 10 under the control of the transfer control unit 2D described later. The transfer stop request is a signal for requesting the stop or interruption of the automatic transfer of telephone data. The mobile phone 10 that has received the transfer stop request stops or suspends the transfer of the telephone data being transferred to the hands-free device 1.

The transfer control unit 2D executes transfer control related to the transfer of telephone data. The transfer control is a control for transferring telephone data from the mobile phone 10. The transfer control unit 2D executes transfer control such as continuing the transfer of telephone data or disabling the transfer.

Continuing the transfer means continuing the transfer of the telephone data being transferred. Disabling transfer means at least one of stopping the transfer of telephone data being transferred and interrupting the transfer of telephone data being transferred.

By the way, for example, when the OS update process occurs, the transfer function itself is forcibly terminated by forcibly terminating the application program at the level of the OS or the basic input / output system (BIOS), or with the forced termination. As a result, if the transfer request is not accepted, the transfer control unit 2D does not transfer the telephone data. At this time, the transfer control unit 2D does not execute the transfer of the telephone data.

The transfer control unit 2D controls the transfer by controlling the transmission timing of the transfer request, the type of the transfer request to be transmitted, the transmission of the transfer stop request, and the like transmitted from the data transfer connection processing unit 2B to the mobile phone 10. Run. The type of transfer request to be transmitted is the type of telephone data for which transfer is requested. The type of telephone data means each of outgoing call history data, incoming call history data, missed incoming call history data, all history data, and telephone directory data.

The transfer control unit 2D executes transfer control for transferring telephone data by controlling the data transfer connection processing unit 2B so as to transmit the transfer request to the mobile phone 10. Further, the transfer control unit 2D executes transfer control for disabling the transfer of telephone data by controlling the data transfer connection processing unit 2B so that the transfer control unit 2D transmits the transfer stop request to the mobile phone 10. do.

By these controls, the transfer control unit 2D performs transfer control that controls the transfer of telephone data by the data transfer connection processing unit 2B. By the transfer control by the transfer control unit 2D, the hands-free device 1 cannot transfer the telephone data from the mobile phone 10, and the transfer of the telephone data is started or continued.

In the present embodiment, the transfer control unit 2D executes the transfer control based on the transfer setting information indicating the setting related to the transfer of the telephone data from the mobile phone 10. The details of the transfer control by the transfer control unit 2D will be described later.

The display control unit 2E controls the display unit 5 to display the display screen by outputting the display instruction to the display unit 5.

For example, it is assumed that a user operates the operation unit 4 to receive a transmission history data display request from the operation unit 4. In this case, the display control unit 2E outputs a display instruction of the transmission history data stored in the working memory 6 to the operation unit 4. By accepting the display instruction, the transmission history data is displayed on the display unit 5. For example, the display unit 5 displays up to five transmission history data.

Further, for example, it is assumed that a user operates the operation unit 4 to receive a call history data display request from the operation unit 4. In this case, the display control unit 2E outputs the display instruction of the incoming call history data stored in the working memory 6 to the operation unit 4. By accepting the display instruction, the incoming call history data is displayed on the display unit 5. For example, a maximum of five incoming call history data is displayed on the display unit 5.

Further, for example, it is assumed that a user operates the operation unit 4 to receive a missed call history data display request from the operation unit 4. In this case, the display control unit 2E outputs a display instruction of the missed call history data stored in the working memory 6 to the operation unit 4. By accepting the display instruction, the missed call history data is displayed on the display unit 5. For example, the display unit 5 displays up to five missed call history data.

Further, for example, it is assumed that a user operates the operation unit 4 to receive a telephone directory data display request from the operation unit 4. In this case, the display control unit 2E outputs the display instruction of the telephone directory data stored in the working memory 6 to the operation unit 4. By accepting the display instruction, the telephone directory data is displayed on the display unit 5.

Next, the operation of the hands-free device 1 of the present embodiment will be described. In the present embodiment, it is assumed that the mobile phone 10 stores the outgoing call history data and the incoming call history data for 20 cases which is the maximum number of storable cases. Then, the case where the mobile phone 10 in this state is carried by a user or the like and reaches the inside of the vehicle 102, and the mobile phone 10 enters the Bluetooth communication range of the hands-free device 1 will be described.

In the present embodiment, it is assumed that the mobile phone 10 as the partner of Bluetooth communication is registered in advance in the hands-free device 1. For example, by inputting a 4-digit password for each mobile phone 10 at the time of initial communication, the hands-free device 1 generates a link key for each mobile phone 10. Then, the link key is stored in each of the mobile phone 10 and the hands-free device 1. The hands-free device 1 selects the mobile phone 10 to be connected by authenticating the link key at the time of initial connection. That is, the mobile phone 10 not registered in the hands-free device 1 is not connected by HFP and PBAP.

In the present embodiment, it is assumed that a plurality of mobile phones 10 to be communication-connected are registered in advance in the hands-free device 1. Further, in the hands-free device 1, priority is set in advance for each of the plurality of mobile phones 10. The priority order may be set in advance by the operation of the operation unit 4 by the user or the like.

First, the flow of transferring telephone data from the mobile phone 10 to the hands-free device 1 will be described.

In the following, a connection by wireless communication using HFP may be described simply as an HFP connection or an HFP connection. Similarly, a connection by wireless communication using HF may be described simply as an HF connection or an HFP connection.

FIG. 4 is a flowchart showing an example of a flow of telephone data transfer processing executed in the hands-free device 1.

The hands-free connection unit 2A selects the mobile phone 10 having the higher priority as the connection target of the HFP (step S1). The hands-free connection unit 2A connects the HFP to the selected mobile phone 10 (step S2). By the process of step S2, the connection of HFP is established between the hands-free device 1 and the mobile phone 10. The establishment of the HFP connection may be referred to as the HFP connection establishment or the HFP connection establishment.

The hands-free connection unit 2A determines whether or not the HFP connection is successful (step S3). When the hands-free connection unit 2A determines that the HFP connection is successful (step S3: YES), the process proceeds to step S4.

In step S4, the data transfer connection processing unit 2B connects the PBAP to the mobile phone 10 determined to have succeeded in connecting the HFP in step S3 (step S4). In step S4, the data transfer connection processing unit 2B executes the initial connection processing. The initial connection process is a connection process for establishing a communication link used for data transfer using PBAP.

Next, the transfer control unit 2D performs data transfer processing of historical data (step S5). The transfer control unit 2D controls the data transfer connection processing unit 2B so that the transfer request of the history data is sequentially transmitted to the mobile phone 10 by the PBAP. The mobile phone 10 transmits the history data to the hands-free device 1 using PBAP in response to the transfer request. By these processes, the history data is automatically transferred from the mobile phone 10 to the hands-free device 1.

When the transfer process of the history data is completed, the transfer control unit 2D starts the transfer process of the telephone directory data (step S6) and performs the transfer process of the telephone directory data. The transfer control unit 2D controls the data transfer connection processing unit 2B so that the transfer request for the telephone directory data is transmitted to the mobile phone 10 by PBAP. The mobile phone 10 transmits the telephone directory data to the hands-free device 1 using PBAP in response to the transfer request. By these processes, the phonebook data is automatically transferred from the mobile phone 10 to the hands-free device 1.

On the other hand, if it is determined in step S3 that the hands-free connection unit 2A has not succeeded in connecting the HFP (step S3: No), the process proceeds to step S7.

In step S7, the hands-free connection unit 2A determines whether or not the mobile phone 10 having the next highest priority exists (step S7). When the hands-free connection unit 2A determines that the mobile phone 10 having the next highest priority exists (step S7: Yes), the process proceeds to step S8. If a negative determination is made in step S7 (step S7: No), this routine ends.

In step S8, the mobile phone 10 having the next highest priority is selected as the connection target of the HFP (step S8). Then, the process returns to step S2.

It is assumed that the telephone communication state of the mobile phone 10 is in the standby state. In this case, if the HFP connection is successful in step S2, the hands-free device 1 can execute the call processing and the outgoing call processing. Specifically, the hands-free device 1 executes a call processing in which an incoming call to the mobile phone 10 is received by the operation unit 4 and a call is made, and a call processing in which the mobile phone 10 is made to make a call by an operation from the operation unit 4. Is possible. Hereinafter, the state of the hands-free device 1 may be referred to as a hands-free standby state.

Further, by the process of step S4, the connection of PBAP is established between the hands-free device 1 and the mobile phone 10. Further, by the processes of steps S2 to S4, the hands-free device 1 is in a state of being simultaneously connected.

Therefore, when the mobile phone 10 approaches the hands-free device 1 and the wireless connection is made by Bluetooth, the data is transferred by PBAP and the HFP is also connected at the same time, and the hands-free standby of the hands-free device 1 is established. The state is maintained.

Further, the hands-free device 1 first connects only the HFP to the mobile phone 10 existing in the Bluetooth communication range to put it in the hands-free standby state, and then performs the initial connection process of PBAP.

Therefore, the hands-free device 1 can reduce the load due to simultaneous processing and suppress the complexity of software due to simultaneous processing even when the initial connection between HFP and PBAP is performed at the same time. Further, in the hands-free device 1, it is possible to suppress the delay in the completion of the HFP connection due to the simultaneous processing. Therefore, the hands-free device 1 can stably and reliably perform simultaneous connection.

Further, the hands-free device 1 can shorten the connection time until the connection of the HFP is completed. Therefore, when the user brings the mobile phone 10 into the vehicle 102, it is possible to make it possible to perform outgoing call processing and incoming call processing by hands-free standby by HFP at an early stage.

Here, when the HFP and the PBAP are simultaneously connected between the hands-free device 1 and the mobile phone 10, the mobile phone 10 may detect an incoming call. In this case, the hands-free device 1 executes the following processing.

FIG. 5 is a flowchart showing an example of a processing flow when an incoming call occurs in the mobile phone 10 while the mobile phone 10 is in the state of simultaneous connection. The state of simultaneous connection is the state of step S4 in FIG.

The transfer control unit 2D determines whether or not an incoming call has been detected by the mobile phone 10 when the HFP is connected and the PBAP is in the process of connecting (corresponding to the process of S4) (step S11). If it is determined that the mobile phone 10 has detected an incoming call (step S11: Yes), the process proceeds to step S12.

In step S12, the transfer control unit 2D stops the connection processing of the PBAP by the data transfer connection processing unit 2B (step S12).

Next, the transfer control unit 2D determines whether or not the incoming call state due to the incoming call detected in step S11 or the call state due to the incoming call has ended and the state has transitioned to the standby state (step S13). The transfer control unit 2D determines in step S13 by determining whether or not the telephone communication state notified by the HFP from the mobile phone 10 indicates a transition from the outgoing state or the call state to the standby state.

If it is determined that the standby state has been entered (step S13: Yes), the process proceeds to step S14. The pattern determined to have transitioned to the standby state in step S13 is, for example, the following case. For example, this is the case where the hands-free device 1 rejects an incoming call. Further, for example, it is a case where the transmission is canceled by the mobile phone 10 on the other side of the transmission. Further, it is a case where the call between the mobile phone 10 and the mobile phone 10 is terminated.

In step S14, the transfer control unit 2D restarts the PBAP connection process from the beginning (step S14), and transfers the telephone data from the mobile phone 10 again (step S15).

As a result, the following effects can be obtained even when the mobile phone 10 receives an incoming call while the PBAP connection process is in progress. That is, the transfer control unit 2D restarts the PBAP connection process from the beginning after the incoming call state or the call state related to the incoming call ends and transitions to the standby state. Therefore, the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data can be appropriately acquired from the mobile phone 10. Therefore, the consistency between these telephone data and the telephone data stored in the mobile phone 10 can be maintained.

In S14, a mode in which the PBAP connection is started from the beginning when the transition from the incoming call state to the standby state is described has been described. This is due to the following reasons.

Specifically, when the incoming call state is detected, new incoming call history data is generated in the mobile phone 10. It is also possible to start the initial connection process of PBAP when the incoming call status is detected. However, if the incoming call is still continuing at the time when the initial connection process is performed and the data transfer is started, it is unknown whether the incoming call is a missed call or a answered call. Therefore, even if the data related to the incoming call is received in this state, the hands-free device 1 cannot determine whether the incoming call is a missed call or a answered call. Therefore, the transfer control unit 2D may restart the initial connection process in the PBAP and the data transfer from the beginning at the timing when the incoming call state changes to a different state.

The telephone communication state of the mobile phone 10 finally transitions to the standby state. Therefore, in step S13, when the transition to the standby state is determined, the mode of proceeding to step S14 is shown. In step S13, when the transition from the incoming call state to the call state is determined, the process may proceed to step S14.

On the other hand, the HFP and the PBAP are simultaneously connected between the hands-free device 1 and the mobile phone 10, and the mobile phone 10 may detect an incoming call during the transfer of telephone data. In this case, the hands-free device 1 executes the following processing.

FIG. 6 is a flowchart showing an example of a processing flow when an incoming call occurs to the mobile phone 10 while the mobile phone is connected at the same time and the telephone data is being transferred. The state of simultaneous connection and the transfer of telephone data is any of the states of step S5, step S6 in FIG. 4, and step S15 in FIG.

The transfer control unit 2D determines whether or not an incoming call has been detected by the mobile phone 10 during the transfer of telephone data (step S21). If it is determined that the mobile phone 10 has detected an incoming call (step S21: Yes), the process proceeds to step S22.

In step S22, the transfer control unit 2D stops the transfer of telephone data by the data transfer connection processing unit 2B (step S22).

Next, the transfer control unit 2D determines whether or not the incoming call state due to the incoming call detected in step S21 or the call state due to the incoming call has ended and the state has transitioned to the standby state (step S23). The transfer control unit 2D determines in step S23 by determining whether or not the telephone communication state notified by the HFP from the mobile phone 10 indicates a transition from the outgoing state or the call state to the standby state.

If it is determined that the standby state has been entered (step S23: Yes), the process proceeds to step S24.

In step S24, the transfer control unit 2D restarts the transfer of telephone data from the beginning (step S24), and accepts the transfer of telephone data from the mobile phone 10 again (step S25).

As a result, the following effects can be obtained even when the mobile phone 10 receives a call during the transfer of telephone data. That is, the transfer control unit 2D restarts the telephone data transfer process from the beginning after the incoming call state or the call state related to the incoming call ends and transitions to the standby state. Therefore, the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data can be appropriately acquired from the mobile phone 10. Therefore, the consistency between these telephone data and the telephone data stored in the mobile phone 10 can be maintained.

Next, the processing of simultaneous connection after the data transfer by PBAP is successful will be described.

In the hands-free device 1, the simultaneous connection state of the HFP and the PBAP is maintained even after the data transfer by the PBAP is completed. Therefore, the hands-free device 1 can start data transfer by PBAP at a predetermined timing. Therefore, even when a new incoming call or outgoing call occurs in the mobile phone 10, the latest telephone data of the mobile phone 10 can be updated on the hands-free device 1 side.

This will be described with reference to FIGS. 7 to 12.

7 to 12, after the HFP is connected in S2 of FIG. 4, there is an incoming call or an outgoing call on the mobile phone 10, and the mobile phone 10 has an incoming call history data including a history of the incoming call and the outgoing call and an outgoing call. The explanation will be given assuming a scene in which historical data is stored. Further, it is assumed that after the HFP is connected in S2 of FIG. 4, the transmission process by the mobile phone 10 via the Bluetooth communication unit 3 is performed in response to the operation of the operation unit 4. In this case, the telephone number of the call destination is sent from the hands-free device 1 to the mobile phone 10 via the Bluetooth communication unit 3. Therefore, the transmission history data including this transmission is also stored in the mobile phone 10.

FIG. 7 is a flowchart of the flow of transfer processing executed by the hands-free device 1 when the transmission processing is performed by the mobile phone 10 by the operation of the operation unit 4 of the mobile phone 10.

As described above, in a state where the HFP connection between the hands-free device 1 and the mobile phone 10 is established, it is possible to perform the transmission process by operating the operation unit 4 of the hands-free device 1. Further, in a state where the HFP connection is established, it is possible to make a hands-free call by performing a transmission process by operating the operation unit 4 of the mobile phone 10.

In this case, in the hands-free device 1, it is necessary to acquire the transmission history data by this transmission processing from the mobile phone 10 and update the history data to the latest state. The hands-free device 1 can determine whether or not the transmission is from the hands-free device 1. Further, the hands-free device 1 can also determine whether or not the call is from the mobile phone 10 by analyzing the telephone communication state notified from the mobile phone 10.

Therefore, the transfer control unit 2D determines whether or not there is a call from the mobile phone 10 while in the standby state (step S31: Yes). The transfer control unit 2D determines in step S31 by determining whether or not the telephone communication state notified from the mobile phone 10 indicates a transmission state.

If an affirmative judgment is made in step S31 (step S31: Yes), the process proceeds to step S32. In step S32, the transfer control unit 2D determines whether or not the transmission state determined in step S31 has transitioned to the standby state (step S32). The transfer control unit 2D determines in step S32 by determining whether or not the telephone communication state notified by the HFP from the mobile phone 10 indicates a transition from the outgoing state or the call state to the standby state.

If it is determined that the standby state has been entered (step S32: Yes), the process proceeds to step S33. The pattern determined to have transitioned to the standby state in step S43 is, for example, the following case. For example, this is the case where the mobile phone 10 rejects the incoming call. Further, for example, it is a case where the transmission is canceled by the mobile phone 10 on the other side of the transmission. Further, it is a case where the call between the mobile phone 10 and the mobile phone 10 is terminated.

In step S33, the transfer control unit 2D acquires telephone data (call history data, incoming call history data, missed call history data, and telephone directory data) from the mobile phone 10 (step S33).

As a result, every time the call from the mobile phone 10 is completed, the call history data, the incoming call history data, the missed call history data, and the telephone directory data can be acquired from the mobile phone 10. Therefore, the consistency between these telephone data and the telephone data stored in the mobile phone 10 can be maintained.

Further, in step S32 of FIG. 7, the transition to the standby state is determined, but the transition to the transmission state may be determined.

FIG. 8 is a flowchart of the flow of the transfer process executed by the hands-free device 1 when the transmission process is performed by the operation of the operation unit 4 of the hands-free device 1.

The transfer control unit 2D determines whether or not there is a transmission from the hands-free device 1 while in the standby state (step S41: Yes).

If an affirmative judgment is made in step S41 (step S41: Yes), the process proceeds to step S42. In step S42, the transfer control unit 2D determines whether or not the transmission state determined in step S41 has transitioned to the standby state (step S42). The transfer control unit 2D determines in step S42 by determining whether or not the telephone communication state notified by the HFP from the mobile phone 10 indicates a transition from the outgoing state or the call state to the standby state.

If it is determined that the standby state has been entered (step S42: Yes), the process proceeds to step S43. The pattern determined to have transitioned to the standby state in step S43 is, for example, the following case. For example, this is the case where the hands-free device 1 cancels the transmission from the own device. Further, for example, the mobile phone 10 cancels the call from the hands-free device 1, or the mobile phone 10 on the other end of the call rejects the call.

In step S43, the transfer control unit 2D acquires telephone data (call history data, incoming call history data, missed call history data, and telephone directory data) from the mobile phone 10 (step S43).

As a result, the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data can be acquired from the mobile phone 10 every time the outgoing call from the hands-free device 1 is completed. Therefore, the consistency between these telephone data and the telephone data stored in the mobile phone 10 can be maintained.

Further, in step S42 of FIG. 8, the transition to the standby state is determined, but the transition to the transmission state may be determined.

FIG. 9 is a modification of FIGS. 7 and 8. FIG. 9 is a flowchart of the flow of transfer processing executed by the hands-free device 1 when the call state is changed to the standby state in FIGS. 7 and 8.

The transfer control unit 2D determines whether or not the hands-free device 1 and the mobile phone 10 have transitioned to the standby state when the hands-free call state or the mobile phone 10 alone is in the call state (step S51). ). When the affirmative judgment is made in step S51, it is the case that the call is terminated by the hands-free device 1, the call is terminated by the mobile phone 10, or the call is terminated by the other party.

If an affirmative judgment is made in step S51 (step S51: Yes), the process proceeds to step S52. In step S52, the transfer control unit 2D acquires telephone data (call history data, incoming call history data, missed call history data, and telephone directory data) from the mobile phone 10 (step S43).

Therefore, the telephone data can be acquired from the mobile phone 10 each time the call is terminated. Therefore, the consistency between the telephone data stored in the hands-free device 1 and the telephone data stored in the mobile phone 10 can be maintained.

FIG. 10 is a modification of FIGS. 7 and 8. FIG. 10 is a flowchart of the flow of transfer processing executed by the hands-free device 1 when the incoming call state is changed to the standby state in FIGS. 7 and 8.

The transfer control unit 2D determines whether or not the state has transitioned to the standby state while in the incoming call state (step S61). If an affirmative judgment is made in step S61, the hands-free device 1 rejects the incoming call, the mobile phone 10 rejects the incoming call, the other party cancels the call, or the call state is entered after the incoming call and the call ends. This is the case when the standby state is entered.

If an affirmative judgment is made in step S61 (step S61: Yes), the process proceeds to step S62. In step S62, the transfer control unit 2D acquires telephone data (call history data, incoming call history data, missed call history data, and telephone directory data) from the mobile phone 10 (step S62).

Therefore, every time the incoming call is terminated, the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data can be acquired from the mobile phone 10. Therefore, the consistency between the telephone data stored in the hands-free device 1 and the telephone data stored in the mobile phone 10 can be maintained.

The hands-free device 1 can also transfer data as soon as it changes from the standby state to the incoming call state. However, there are two types of incoming calls: missed calls that did not answer the incoming call and answered incoming calls that changed from the incoming call state to the call state. However, the telephone communication state eventually transitions to the standby state. Therefore, the transfer control unit 2D may acquire data indicating whether the incoming call is a missed call or an answering call from the mobile phone 10 when the standby state is entered. In this case, the display control unit 2E can display a display screen indicating whether the incoming call is a missed call or an answering call on the display unit 5.

The transfer control unit 2D may control the timing of data transfer by using a timer.

FIG. 11 is a flowchart showing an example of a flow of timing control of data transfer using a timer value.

When the data transfer connection processing unit 2B establishes the PBAP connection, the transfer control unit 2D sets the timer value (step S71). The transfer control unit 2D decrements the set timer value at predetermined time intervals (step S72). When the transfer control unit 2D determines that the timer value has timed up (step S73: Yes), the transfer control unit 2D proceeds to step S74.

In step S74, the transfer control unit 2D acquires outgoing call history data, incoming call history data, missed incoming call history data, and telephone directory data from the mobile phone 10 (step S74).

By the process shown in FIG. 11, the hands-free device 1 can periodically acquire outgoing call history data, incoming call history data, missed incoming call history data, and telephone directory data from the mobile phone 10. Therefore, the hands-free device 1 can maintain the consistency between the telephone data of the mobile phone 10 and the telephone data of the hands-free device 1.

FIG. 12 is a flowchart showing a flow when data transfer is started by using an operation of the operation unit 4 by the user as a trigger.

When the display control unit 2E receives a change instruction of the display screen by the operation of the operation unit 4 by the user, the display control unit 2E switches the display screen to the history data or the telephone directory data instructed to change. Specifically, the display control unit 2E determines whether or not the display screen has been transitioned to any of the outgoing call history data, the incoming call history data, the missed call history data, and the telephone directory data (step S81).

If an affirmative determination is made in step S81 (step S81: Yes), the transfer control unit 2D transfers telephone data from the mobile phone 10 (step S82).

In this case, each time the telephone data displayed on the display unit 5 is switched, the telephone data is automatically transferred from the mobile phone 10 to the hands-free device 1.

In the processes shown in FIGS. 7 to 12, the hands-free device 1 has described a mode in which telephone data is periodically acquired from the mobile phone 10. However, the telephone directory data included in the telephone data takes time to be converted into the Vcard format. Further, the amount of data in the telephone directory data is larger than the amount of data in the history data. Therefore, the load on the mobile phone 10 and the hands-free device 1 is large, which may cause a factor of reducing the battery capacity of the mobile phone 10 and the hands-free device 1.

Therefore, when the PBAP connection is established between the mobile phone 10 and the hands-free device 1, the hands-free device 1 transfers historical data, which is phone data other than the phonebook data, from the mobile phone 10 at predetermined timings. You may get it. As a result, the processing of the mobile phone 10 and the hands-free device 1 can be reduced, and the decrease in the battery capacity thereof can be suppressed.

Further, the transfer control unit 2D of the hands-free device 1 transfers only the incoming call history data and the missed incoming call history data when there is an incoming call, and transfers only the outgoing call history data when there is an outgoing call. Transfer control may be used. As a result, unnecessary data transfer can be omitted, the processing of the mobile phone 10 can be reduced, and the decrease in the battery capacity thereof can be suppressed.

The processes described with reference to FIGS. 7 to 12 may be performed individually or in combination of a plurality of processes.

The process executed by the hands-free device 1 with respect to the data transferred from the mobile phone 10 to the hands-free device 1 will be described.

In the following, it is assumed that the number of data included in the history data that can be stored in the working memory 6 of the hands-free device 1 is smaller than the number of data included in the history data automatically transferred from the mobile phone 10. explain. Specifically, the case where the number of data included in each of the outgoing call history data, the incoming call history data, and the missed incoming call history data automatically transferred from the mobile phone 10 is 20 will be described. Further, the case where the number of data included in each of these historical data that can be stored in the working memory 6 is 5 will be described.

The display control unit 2E of the control unit 2 discards the transmission history data having an old transmission date and time among the transmission history data automatically transferred from the mobile phone 10. Then, the display control unit 2E stores the transmission history data for five cases with new transmission dates and times in the working memory 6. Further, the display control unit 2E similarly stores the history data for five cases with new transmission dates and times in the working memory 6 for the other history data (incoming call history data, missed incoming call history data).

Then, the display control unit 2E may display the stored history data and the telephone directory data on the display unit 5 in response to an operation instruction of the operation unit 4 by the user.

The incoming call history data is historical data that responds to an incoming call. The missed call history data is the history data that did not answer the incoming call.

Therefore, when displaying the history data in a list at the same time, the display control unit 2E corresponds to at least one of the icon figure representing the received call and the icon figure representing the missed call which is the unanswered call. It is preferable to display each historical data. As the icon figure representing the answered incoming call, for example, a figure consisting of a combination of a handset and an arrow may be used. Further, as the icon figure representing the missed call, for example, a figure composed of a combination of the handset and the x mark may be used.

Further, the data transfer connection processing unit 2B specifies the number of cases (5 cases in this embodiment) that the hands-free device 1 should automatically transfer to the mobile phone 10 when connecting the PBAP, and the outgoing date and time and the incoming call date and time are set. The new outgoing call history data, incoming call history data, and missed incoming call history data may be preferentially stored in the work memory 6.

In the mobile phone 10, it is necessary to convert the data format of the telephone directory data into the data format of "vCard" defined by the Bluetooth communication standard and transfer the data to the hands-free device 1. Further, the telephone directory data is generally updated less frequently than the historical data such as the outgoing call history data and the incoming call history data.

Therefore, the transfer control unit 2D may control the phonebook data to be transferred after the history data such as the outgoing call history data, the incoming call history data, and the missed call history data are transferred from the mobile phone 10. .. Further, even if the transfer control unit 2D controls to transfer the telephone directory data when a predetermined operation instruction is received by the operation of the operation unit 4 by the user after the history data is transferred from the mobile phone 10. good.

In this case, the history data with a high frequency of data update is transferred to the hands-free device 1 with priority over the telephone directory data with a low frequency of data update. Further, the history data that does not require data conversion for transfer can be transferred from the mobile phone 10 to the hands-free device 1 before the telephone directory data that requires data conversion for transfer. Therefore, in the hands-free device 1 of the present embodiment, convenience can be improved. Further, it may be possible to select whether or not to transfer the telephone directory data by the operation of the operation unit 4 by the user.

Further, in the above description, the form of automatically transferring the outgoing call history data, the incoming call history data, the missed incoming call history data, and the telephone directory data has been described, but a part of the incoming call history data may be manually transferred. In this case, the hands-free device 1 may accept the selection of manual transfer and automatic transfer from the user and set in advance. Then, the hands-free device 1 may perform PBAP processing according to this setting. For example, if the user does not set the automatic transfer, only the outgoing call history data, the incoming call history data, and the missed incoming call history data are automatically transferred. On the other hand, when the telephone directory data is transferred by manual setting, only the telephone directory data is stored in the non-volatile storage memory 7. Then, the stored data may be read from the storage memory 7 and used as telephone directory data at the next startup of the hands-free device 1.

Further, the control unit 2 of the hands-free device 1 stores the outgoing call history data, the incoming call history data, and the telephone directory data transferred from the mobile phone 10 separately for each transfer source mobile phone 10 and stores them in the work memory 6. May be good. In this case, the control unit 2 generates a link key based on the ID of the transfer source mobile phone 10 and the ID of the hands-free device 1. Then, the control unit 2 may store the link key and the telephone data transferred from the mobile phone 10 identified by the ID used to generate the link key in the working memory 6 in association with each other. The control unit 2 generates a link key using the ID of the mobile phone 10 every time the telephone data is transferred from the mobile phone 10. Then, the control unit 2 may update the telephone data by storing the transferred telephone data in the working memory 6 in association with the generated link key.

By storing the telephone data separately for each transfer source mobile phone 10, the hands-free device 1 can manage the telephone data for each mobile phone 10. Further, in this case, it is not necessary to receive the telephone directory data from the mobile phone 10 every time the power supply to the hands-free device 1 is started. Therefore, the user can quickly use the telephone directory data corresponding to his / her own mobile phone 10 in the hands-free device 1. In addition, the convenience when using the telephone directory function can be significantly improved.

In this embodiment, a mode in which the telephone data transferred from the mobile phone 10 is stored in the working memory 6 has been described as an example. However, at least one type of telephone data may be stored in the storage memory 7. For example, the history data may be stored in the working memory 6 and the telephone directory data may be stored in the storage memory 7. Further, the history data and the telephone directory data may be stored in the storage memory 7.

Next, the transfer control unit 2D will explain in detail the transfer control by the transfer control unit 2D based on the transfer setting information indicating the setting related to the transfer of the telephone data from the mobile phone 10.

The transfer control unit 2D is a data transfer connection processing unit so as to execute the transfer or retransfer of the telephone data from the mobile phone 10 based on the transfer setting information indicating the setting related to the transfer of the telephone data from the mobile phone 10. Execute transfer control that controls 2B.

Data transfer The transfer control is executed so that the connection processing unit 2B executes the transfer or re-transfer of the telephone data from the mobile phone 10 based on the transfer setting information indicating the setting related to the transfer of the telephone data from the mobile phone 10. do.

Here, the transfer setting information will be described. The transfer setting information includes the type setting indicating the type of telephone data to be transferred, the period setting indicating the period of historical data of telephone data to be transferred, and the number of cases to transfer telephone data. At least one of the number settings to be set is included.

The type setting indicating the type of telephone data to be transferred is the type of telephone data for which telephone data is transferred. The type of telephone data includes at least one of outgoing call history data, incoming call history data, missed incoming call history data, and telephone directory data, and transfer settings for telephone data can be set for each. In addition, the photo data of the profile included in the telephone directory may be included in the type setting of the telephone data.

The period setting indicating the period of the historical data of the telephone data to be transferred is the period setting based on the date and time included in the historical data of the telephone data for executing the transfer of the telephone data. For example, when it is desired to transfer one week's worth of history data stored in the mobile phone 10, the period setting of the history data is set to one week. Further, the period setting of the date and time included in the history data of the telephone data is not limited to one week.

Setting the number of cases for transferring telephone data The number setting is the number of telephone data for which telephone data is transferred. The number of telephone data may be the number set for each type or the total number of telephone data to be transferred.

By providing transfer setting information indicating settings related to the transfer of telephone data from the mobile phone 10, by narrowing down the transfer target of the telephone data regarding the transfer of telephone data from the mobile phone 10, unnecessary data that does not need to be transferred is provided. It is possible to prevent the transfer, and it is not necessary to transfer the telephone data having a large amount of data, and the time required for transferring the telephone data can be shortened.

Further, the transfer setting information includes at least one setting of the number of retries for setting the number of times to re-transfer the telephone data and the retry time for setting the time for re-transferring the telephone data.

The number of retries for setting the number of times to re-transfer the telephone data is the number of times to execute the re-transfer of the telephone data when the transfer of the telephone data from the mobile phone 10 fails. The number of retries may include an upper limit of the number of retries.
