The implementation of the invention

The present invention is explained with reference to the above drawings, illustrating an embodiment of the invention with respect to an automobile hands-free device with a hands-free function and a Bluetooth function. Figure 1 shows a functional diagram of the main part of the car speakerphone. The hands-free car device 1 includes a control section 2, a Bluetooth communication section 3 (means or short-range communication unit), an operation section 4, a display section 5, a working memory 6, a storage memory 7, a microphone 8, a speaker 9.

The control section 2 may operate as a means or control unit, a means or determining unit, a display control means or unit, a transmission protocol control means or unit, a transmission protocol termination tool or unit, a speakerphone means or control unit, a means or establishment unit connection via hands-free protocol, means or unit for maintaining the connection, means or unit for setting up the transfer of the phone book, means or unit for determining data transfer and means or lock for executing instructions of a non-automatic transfer protocol. The control section 2 controls all operations, such as the connection operation and the data management operation of the car navigation device 1. The Bluetooth communication section 3 can function as a means or unit for receiving outgoing call history data, a means or unit for receiving incoming call history data, a means or unit for receiving data . If the cellular telephone with the Bluetooth communication function (hereinafter referred to as the cellular telephone) is in the Bluetooth wireless communication area, the Bluetooth communication section 3 establishes a wireless connection with the cellular telephone 10 in the Bluetooth wireless communication area and establishes a connection compatible with the Bluetooth communication protocol. The cell phone 10 responds to a Bluetooth system capable of functioning, in particular, as a means or unit for short-range wireless communication.

The Bluetooth communication section 3 of the present embodiment is compatible with a known hands-free profile (HFP) for making a hands-free phone call and a phone book access profile (PBAP) for transmitting phone book data and outgoing and incoming call history data.

In the context of this document, the above profiles mean communication protocols defined for all functions. Offline, i.e. without connecting the HFP to the car navigation device 1 as to a speakerphone, the cellular telephone 10 establishes a connection of the cellular telephone to a base station (not shown) in the cellular network and independently performs an outgoing call and an incoming call process. In the context of this document, the cell phone 10 performs an outgoing call process, for example, as follows. The user controls the dial buttons ("0" to "9" on the numeric keypad ") (not shown) and enters the phone number of the recipient of the call. Then, when an outgoing call button (not shown) is pressed, the telephone number is transmitted as the number of the call recipient. The cell phone 10 can thus make a phone call to the cell phone of the recipient of the call.

Further, the cellular telephone 10 performs an incoming call process, for example, as follows. In response to the cellular telephone as the source of the call transmitting the telephone call to the cellular telephone 10 as the recipient of the call, after receiving the incoming call through the base station, the cellular telephone receives the telephone number of the cellular telephone of the calling source through the base station. Then, when the user presses the answer button (not shown), the cellular telephone 10 can answer the calling cellular telephone and make a telephone call with the cellular telephone as the source of the call.

Additionally, the cell phone 10 has a clock section (not shown) that captures dates and times (clock dates and times). In the outgoing call process described above, one correspondence data element is formed between the telephone number of the recipient and the date and time of the outgoing call. The destination telephone number is entered using the dial button, while the date and time of the outgoing call are measured by the clock section. A plurality of correspondence data elements constitute outgoing call history data that is stored in the cellular telephone 10. Additionally, in the above incoming call process, one correspondence data element is generated between the source telephone number and the incoming call date and time. The source telephone number is received by the base station, while the date and time of the incoming call are measured by the clock section. A plurality of correspondence data items constitute incoming call history data that are stored in the cellular telephone 10.

Moreover, when there is no answer to an incoming call, one element of correspondence data is generated between the source telephone number and the date and time of the incoming call. The source telephone number is received by the base station, while the date and time of the incoming call are measured by the clock section. A plurality of correspondence data elements constitute missed incoming call history data that is stored in the cellular telephone 10. Moreover, the cellular telephone 10 comprises a phone book data that includes a plurality of data elements, each data element having a correspondence between the telephone number and the registration name . Phonebook data is prepared as follows. The user enters each telephone number and corresponding registration name into the corresponding storage, for example, approximately 500 data elements about telephone numbers and registration names corresponding to each other, in read-only memory (not shown).

In the context of this document, when phonebook data is stored, the aforementioned login names are included in the aforementioned outgoing call history data and incoming call history data. In more detail, it is checked whether the source telephone number received from the base station is the telephone number registered in the phone book data and in accordance with the registration name. When such a match is in the phone book data, the corresponding incoming call history data is received to include the phone number, date and time of the incoming call, and registration time. Missed incoming call history data is also provided to include the phone number, date and time of the incoming call, and registration time through the same processing. Further, with respect to the outgoing call history data, it is also checked whether the telephone number of the recipient of the call transmitted in the above outgoing call process is the telephone number registered in the telephone number. If compliance is confirmed, outgoing call history data is provided to include the data and time of the outgoing call, the recipient's phone number and registration name.

Thus, the user reads the phone book data and selects and calls one phone number, thereby safely performing the outgoing call process with a simple operation without having to enter all the digits corresponding to the digits of the phone number one by one. In addition, the cellular telephone 10 may store, for example, about 20 data items for each outgoing call history data, incoming call history data and missed incoming call history data. Whenever one of the processes of an outgoing call, an incoming call, and a missed incoming call occurs, the oldest data item is automatically deleted. Outgoing call history data, incoming call history data, missed incoming call history data are updated accordingly. It should be noted that the cell phone 10 is compatible with the known HFP for hands-free calling and PBAP for transmitting phone book data and transmitting outgoing / incoming call history data.

Being compatible with PBAP, which specifies the automatic transmission of outgoing / incoming call history data, the cellular telephone 10 connects via PBAP immediately after establishing communication with the Bluetooth communication section 3 and automatically transmits the telephone book data that is currently stored. Moreover, outgoing call history data, incoming call history data and missed incoming call history data that are currently stored are transmitted automatically. Thus, the car navigation device 1 is located in the Bluetooth wireless zone, the cell phone 10 automatically transmits outgoing call history data that stores up to 20 data items based on outgoing call processes performed in the past by the cell phone 10 itself, incoming call history data that store up to 20 data elements based on incoming call processes performed in the past by the cell phone itself, and history data of incoming calls not received, which store up to 20 data elements x on the basis of processes not received an incoming call made in the past by the cellular phone.

The operation section 4 may function as an operating means or unit, allowing the user to actuate it. For example, the operation section 4 includes a touch key formed on the display section 5. The operation section 4 defines a user operation and provides a corresponding operation signal to the control section 2. The display section 5 may function as a display means or unit. The display section 5 displays the display window based on the display signal inputted from the control section 2. As shown in FIG. 11 (a) and FIG. 12 (a), for example, a display window showing dial keys located respectively from “0” to “9” is displayed for a user to enter a telephone number.

The working memory 6 can function as a means or unit for storing outgoing call history data, as a means or unit for storing incoming call history data, as a means or unit for storing data, and includes volatile memory. The working memory 6 stores data of the history of outgoing calls, data of the history of incoming calls, data of the history of missed incoming calls, data of the phone book, which were transferred automatically from the cell phone without any user action. It should be noted that the working memory 6 can store each of the outgoing call history data, incoming call history data and missed incoming call history data, for example, up to five data items, respectively. Storage memory 7 includes non-volatile memory and stores various data.

When a user executes a request to display outgoing call history data by means of an operation section 4, the control section 2 causes the display section 5 to display outgoing call history data stored in the working memory 6. When a user performs a request to display outgoing call history data by an operating section 4, section 2 of the control causes the display section 5 to display the history data of incoming calls stored in the working memory 6. When the user executes the display request the phone book data by the operation section 4, the control section 2 causes the display section 5 to display the phone book data stored in the working memory 6. In addition, as explained above, in the car navigation device 1 of the present embodiment, the number of outgoing call history data elements or the number of elements the data history of incoming calls stored in the working memory is 5, respectively. The maximum number of data elements displayed in the display section 5 is also five for each of the data (see Fig. 11 (b), (c), Fig. 12 (b), (c)).

The microphone 8 functions as an audio input means or unit for inputting sounds. When making a phone call using the cell phone 10, sounds made by the user fall into the microphone 8. The loudspeaker 9 functions as a means or unit for audio output. When making a hands-free phone call using a cell phone 10, sounds received from the other side are output through the speaker 9. Thus, when a Bluetooth connection is established between the Bluetooth communication section 3 and the cell phone 10 and then a wireless connection via the HFP protocol is established, control section 2 causes the Bluetooth section 3 to transmit the sound inputted from the microphone 8 to the cell phone 10. Simultaneously with the cell phone 10 transferring to the cell phone network, the Bluetooth section 3 transmits the sound and from the cellular telephone network and displays them through a loudspeaker.

The car navigation device 1 further includes, in addition to the functional blocks shown in the drawings, the following functional blocks required for navigation: a GPS device as a determinant of the present location for determining the present location of the vehicle; a route finding section for finding a route from a current location to a destination; a card data reading section for reading card data from a data medium that stores map data; VICS reception section (registered trademark) for receiving VICS information distributed from the VICS center; a speech recognition section for recognizing speech sounds made by a user.

In this configuration, the car navigation device 1 retrieves the GPS date data that the GPS device receives from the GPS satellite, thereby obtaining a date and time that are used as the date and time of the outgoing call or the date and time of the incoming call. In addition, the date and time extracted from the GPS date information are absolute date and time, which have very high accuracy.

The aforementioned car navigation device 1 is configured to turn on or off together with turning on or off the electrical switch. The electrical switch is used to turn on or off the power supply of electrical appliances in the car.

When the electrical circuit breaker changes its state from on to off due to user action, the power supply of electrical appliances switches from on to off. In this case, the data that was previously stored in the storage memory 7 is stored without deletion, while the outgoing call history data, incoming call history data, missed incoming call history data and phone book data that were previously stored in the working memory 6 are deleted.

Operation in this configuration is explained with reference to FIG. 2 in FIG. 16. The following is assumed here. Cell phone 10 already contains (stores) a maximum of 20 data elements of the history of outgoing calls, a maximum of 20 data elements of the history of incoming calls and a maximum of 20 data elements of the history of missed incoming calls. Next, the user who wears the cellphone 10 approaches the car and sits in it; then, the aforementioned electrical switch is turned on, which leads to the appearance of the cell phone 10 in the Bluetooth communication area of the car navigation device 1.

Firstly, the following explains with reference to FIG. 2 a procedure in which the control section 2 of the car navigation device 1 receives outgoing call history data, incoming call history data, missed incoming call history data and phone book data from the cellphone 10. In addition the user pre-registers the cell phone 10, which acts as a communication partner for the car navigation device 1 when connecting Bluetooth. For example, a four-digit password is entered for each cell-phone during the establishment of the first connection; then, the car navigation device 1 or the cell phone 10 generate a connection key known only to them alone, and the generated key is registered and stored in both of them. At the first connection, a connection key is required for the authentication process, thereby allowing you to select the cell phone that should be connected. Thus, an unregistered cell phone cannot establish a connection using HFP and a connection using PBAP. Basically, the car user’s cell phone is pre-registered to allow wireless connection using HFP and wireless connection using PBAP.

In the present embodiment, a plurality of cell phones 10 are registered in the car navigation device 1 as a connection object, and the priority order is pre-set using section 4. The control section 2 stores the priority order. This is because the driver can have multiple cell phones.

In the present embodiment, the following is contemplated. The Bluetooth communication section 3 of the car navigation device 1 is compatible with both protocols for wireless communication using HFP and wireless communication using PBAP; in addition, simultaneous connection can be made using both protocols, which is called multi-profile connection. However, any simultaneous connection process is decided not to be used in the present embodiment. This is due to the following three reasons: (1) It is assumed that the cell phone 10 as a connection partner must be compatible with the wireless connection using HFP and with the wireless connection using PBAP as the car navigation device 1, but not compatible with the simultaneous connection. (2) It is contemplated that the cellular telephone 10 as a connection partner should be compatible with a wireless connection using HFP and with a wireless connection using PBAP as a car navigation device 1 and further compatible with simultaneous connection. However, for servicing a simultaneous connection, the software executed by the Bluetooth communication section 3 of the car navigation device 1 becomes complicated, which calls into question the reliability of the connection. (3) The car navigation device 1 must be connected to any of the cell phones 10 compatible with wireless connection using HFP and wireless connection using PBAP, which are produced by many manufacturers in the world.

For the above reasons, the car navigation device 1 of the present embodiment is provided as follows. To eliminate, as far as possible, simultaneous wireless connection using HFP and wireless connection using PBAP, the serial connection is adapted so that the wireless connection using HFP and the wireless connection using PBAP use time sharing, which is a more reliable procedure for wireless connection with using HFP and wireless using PBAP.

Returning to the explanation, the control section 2 selects a cell phone 10 having high priority as a connection object for wireless connection using the HFP (step S1). It should be noted that the present embodiment, without making a connection using PBAP, is primarily trying to establish an initial connection using HFP, thereby starting the connection. The reason will be mentioned later.

Then, the control section 2 automatically establishes a connection using the HFP with the selected cell phone 10 (step S2). It is determined whether the wireless connection using the HFP was established successfully (step S3). When the control section 2 determines that the wireless connection using the HFP is successfully established (“YES” in step S3), the wireless connection using the HFP immediately automatically disconnects (step S4). The control section 2 is automatically wirelessly connected using PBAP with the cellular telephone 10 to which the wireless connection using the HFP has been successfully established (step S5).

Then, the control section 2 transmits a data transmission request to the cellular telephone 10 to start the process of transmitting outgoing call history data, incoming call history data, missed incoming call history data (step S6). As the process of transmitting outgoing call history data, incoming call history data, missed incoming call history data, the car navigation device 1 receives data (step S6). After the transfer process is completed, the control section 2 transmits a data transfer request to the cellular telephone 10 to complete the phone book data transfer process, and the car navigation device 1 then receives the data (step S7). After the phonebook data transfer process is completed, the wireless connection using PBAP is disconnected (step S8).

The control section 2 is again automatically connected wirelessly using HFP to the cellular telephone 10 to which the wireless connection using PBAP was disconnected (step S9), then goes into the hands-free call waiting process. Thus, in the present embodiment, the wireless connection is automatically sequentially changed in the order of HFP -> PBAP -> HFP. Thus, it becomes possible to conduct a stable process of secure connection with cell phones, which are produced by a large number of manufacturers and are compatible with wireless using HFP and wireless using PBAP; this eliminates the need to complicate the software process in the car navigation device 1.

In contrast, when the control section 2 determines that the wireless connection using the HFP has not been successfully established (“NO” in step S3), it determines whether the cell phone 10 having the following priority order exists (step S10). When it determines that there is a cell phone 10 having the following priority order (“YES” in step S10), the control section 2 selects the cell phone 10 having the next priority order as the connection object (step S11). Processing then returns to step S2 and is repeated as described above.

Here, the control section 2 operates in the above-described process for transmitting outgoing call history data, incoming call history data, missed incoming call history data as follows. For outgoing call history data, as shown in FIG. 3 (a), the control section 2 receives outgoing call history data that contains registration names, destination phone numbers and outgoing call dates and times from the cellular telephone 10, and stores the received data in working memory 6. With respect to incoming call history data, as shown in FIG. 4 (a), the control section 2 receives incoming call history data that contains registration names, source telephone numbers and incoming dates and times x calls from the cellular telephone 10, and stores the received data in the working memory 6. In relation to the history data of missed incoming calls, as shown in Fig. 3 (a), the control section 2 receives the history data of missed incoming calls, which contain registration names, telephone source numbers and dates and times of missed incoming calls from cell phone 10, and stores the received data in working memory 6.

After that, when a display request is applied to the outgoing call history data, the incoming call history data, the incoming missed call history data, the control section 2 causes the display section 5 to display the outgoing call history data, the incoming call history data and the missed incoming call history data, which are stored in the working memory 6. Thus, without reading the registration name from the phone book data stored in the working memory 6, the registration name transmitted from the cellular phone 10 is displayed in the display section 5.

When a wireless connection using the HFP is established in step S9 by the control section 2, it becomes possible for the operation section 4 of the car navigation device 1 to execute the outgoing call process and the incoming call process. After receiving the outgoing call history data, the incoming call history data, the missed incoming call history data from the cellular telephone 10 (after establishing the wireless connection using the HFP in step S9), the control section 2 performs a new outgoing call process, a new incoming call process, a new missed process an incoming call through the operation of the operating section 4. Then, when a request for display appears with respect to outgoing call history data, incoming call history data, data Stora missed incoming call, the control section 2 searches the phone book data, which were transferred from the cellular phone 10, the registration name corresponding to the call recipient telephone number of outgoing call process, incoming call telephone number or source process phone number of the missed incoming call process source. If the corresponding registration name exists in the phone book data, then the registration name is displayed in the display section 5 (see FIG. 3 (c), FIG. 4 (c), FIG. 5 (c)).

Thus, in the case where the outgoing call process to Mr. Oomori’s phone number is performed, when Mr. Oomori’s registration name is already in the phonebook data, the control section 2 reads the registration name “Oomori OO” from the phonebook data and displays the outgoing call history data, including the registration name “Oomori OO” in the display section 5. On the contrary, in the case when the process of a new incoming call from Mr. Yamaoka’s phone number is performed, when Mr. Yamaoka’s registration name is already registered in the phonebook data, the control section 2 reads the “Yamaoka OO” registration name from the phonebook data and displays the incoming call history data, including the registration name "Yamaoka OO" in the display section 5. As for the missed incoming call, the control section 2 reads the Kaneda OO registration name from the phone book data and displays the history of missed incoming calls, including the Kaneda OO registration name, in the display section 5.

In addition, you may receive a request to display all history data, which requests all history data containing outgoing call history data, incoming call history data, missed incoming call history data, displayed in date and time order, starting with the newest. In such cases, with regard to the incoming call history data and the missed incoming call history data, regardless of whether the incoming telephone number or the missed incoming telephone number is identical (or overlapping) to another telephone number, the control section 2 selects a predetermined number of telephone numbers from the most new by the date and time of the incoming call or by the date and time of the missed incoming call from all data of the history of incoming calls and data of the history of missed incoming calls, and displays the selected e. In contrast, with respect to outgoing call history data, the control section 2 selects for display only the latest items from data items having identical source telephone numbers (see FIG. 6). Thus, since the telephone numbers of the Yeshida OO source overlap in the present embodiment, the control section 2 displays only the outgoing call history data item having the outgoing call date and time 12:15 on August 10.

Next, it will be explained below with reference to FIG. 7 to FIG. 16, a procedure in which the control section 2 of the car navigation device 1 receives outgoing call history data, incoming call history data, missed incoming call history data and telephone data from the cellular telephone 10 books, saves the received data and then makes an outgoing call using the saved outgoing call history data, incoming call history data, missed incoming call history data. In addition, although the following explains the procedure for outgoing call history data and incoming call history data, the procedure related to the missed incoming call history data is the same.

In the car navigation device 1, the control section 2 determines that the cell phone 10 is in the Bluetooth communication area of the car navigation device 1, and the Bluetooth communication section 3 establishes a connection with the cell phone 10 (“YES” in step S21). The control section 2 then waits for the automatic transmission of outgoing call history data, incoming call history data and phone book data from the cell phone 10 of the Bluetooth communication section 3.

When the control section 2 determines that the outgoing call history data, the incoming call history data and the phone book data are automatically transmitted from the cellphone 10 (“YES” in step S22), the control section 2 stores outgoing call history data, history data in the working memory 6 incoming calls and phone book data that were transferred automatically from the cell phone 10 (step S23).

More specifically, the number of outgoing call history data elements or incoming call history data transmitted from the cellular telephone 10 is 20, respectively, while the number of outgoing call history data elements or incoming call history data stored in the working memory 6 is five, respectively . Thus, the number of outgoing call history data elements or incoming call history data stored in the working memory 6 is smaller than the number of outgoing call history data elements or incoming call history data transmitted automatically from the cellular telephone 10, thereby requiring the following process.

Thus, regarding the outgoing call history data, the control section 2 cancels the data element having the old outgoing call date and time among the outgoing call history data automatically transmitted from the cellphone 10, thereby storing mainly data elements having the most recent date in the working memory 6 and the outgoing call time from the outgoing call history data automatically transmitted from the cellular telephone 10. Further, with respect to the incoming call history data, the control section 2 cancels the item data having the old date and time of the outgoing call among the incoming call history data automatically transmitted from the cellular telephone 10, thereby storing mainly in the working memory 6 data elements having the latest incoming call date and time from the incoming call history data automatically transmitted from cell phone 10.

Thus, immediately after the outgoing call history data was automatically transferred from the cellphone 10, the control section 2 contains the outgoing call history data shown in FIG. 9 (a) as the outgoing call history data in the working memory 6. When the user then performs an operation for displaying outgoing call history data, the control section 2 displays a display window in a display section 5, as shown in FIG. 11 (b). Further, immediately after the incoming call history data was automatically transmitted from the cellphone 10, the control section 2 contains the incoming call history data shown in FIG. 10 (a) as the incoming call history data in the working memory 6. When the user then performs an operation for displaying incoming call history data, the control section 2 displays a display window in the display section 5, as shown in FIG. 12 (b).

Thus, when the cell phone 10 and the car navigation device 1 establish a Bluetooth connection between the hundredth, the outgoing call history data and the incoming call history data that were stored before the cell phone 10 established the Bluetooth connection are automatically transferred to the working memory 6 of the car navigation device 1. The cell phone 10 and the car navigation device 1 thus constitute a single telephone system allowing the user to make hands-free calls. After the cell phone 10 and the car navigation device 1 form a single telephone system, the user can perform outgoing call operations by pressing one of the dial keys from the outgoing call history, incoming call history and phone book data. It becomes possible to expect an incoming call from a cellular telephone network.

The present embodiment adopts, as a Bluetooth connection procedure, a profile switching that is performed in sequence performing a wireless connection using PBAP in step S5 -> terminating a wireless connection using PBAP in step S8 -> making a wireless connection using HFP in step S9. Accordingly, after the wireless connection using the HFP is established in step S9, a new incoming call may be received on the cellular telephone 10, or a new outgoing call may be made using the operation section 4. In such cases, the cellular telephone 10 as a result stores in its own memory Incoming call history data and Outgoing call history data, which include the aforementioned incoming and outgoing calls. Thus, to obtain updated history data of outgoing and incoming calls from the cellular telephone 10, the control section 2 of the car navigation device 1 can perform a wireless connection using PBAP (simultaneous connection) during a wireless connection using HFP.

Conversely, in order to prevent a simultaneous connection, a serial connection can be used as far as possible, which disconnects the wireless connection using HFP and performs the wireless connection using PBAP. However, when connected in series, the cellular telephone 10 and the car navigation device 1, which make up a single telephone system, are practically separated from each other, thereby leading to a state in which a wireless telephone call cannot be made. Thus, in the present embodiment, after the wireless connection using the HFP was established in step S9, and after supporting only the wireless connection using the HFP, the car navigation device 1 receives the latest outgoing and incoming call history data from itself and supports them without the help of a cell phone 10. Such a feature will be explained later.

The control section 2 determines whether the user has performed an outgoing call operation by pressing the dial button (step S24). The control section 2 determines whether the user has performed an outgoing call operation using the outgoing call history (step S25). The control section 2 determines whether the user has performed an outgoing call operation using the incoming call history (step S26). The control section 2 determines whether the user has performed an outgoing call operation using the phone book (step S27). The control section 2 determines whether an incoming call has arrived from the cellular telephone network (step S28).

When the control section 2 determines that the user performs the outgoing call operation by pressing the dial button (“YES” in step S24), the control section 2 performs the outgoing call process using the telephone number entered by the user by pressing the dial button as the telephone number of the call recipient (step S29). When the control section 2 ends the outgoing call process by pressing the dial button, as shown in FIG. 9 (b), the control section 2 deletes the data item having the oldest outgoing call date and time among the outgoing call history data currently stored in the working memory 6 (step S30). The control section 2 stores the additional new outgoing call data element as its own outgoing call history data in the working memory 6 (step S31).

When the user enters, for example, the telephone number “09000000100” by pressing the dial buttons and makes an outgoing call using the telephone number “09000000100” as the telephone number of the call recipient, the control section 2 further stores an outgoing call history data element representing the telephone number “09000000100” as own data of the history of outgoing calls in the working memory 6, as illustrated in Fig.9 (b). Further, the control section 2 stores, as a time stamp, the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the outgoing call, corresponding to the telephone number “09000000100”.

Thus, in FIG. 9 (b), the date and time of the outgoing call of the newest telephone number “09000000100” is the time that the GPS device of the car navigation device 1 received, while the other dates and times of the outgoing calls of the remaining four phone numbers are times received by the watch device of the cellular telephone 10. Further, when the user then performs an operation to display the outgoing call history data, the control section 2 displays the display window in the display section 5, as for now Referring to FIG. 11 (c).

When the user presses the HISTORY button 4a and then the OUTGOING CALL HISTORY button 4b, the control section 2 determines that the user performs an outgoing call operation using the outgoing call history (“YES” in step S25). The control section 2 accesses the outgoing call history data stored in the working memory 6 (step S32). The control section 2 accesses the phone book data stored in the working memory 6 (step S33). As shown in FIG. 11 (b) and FIG. 11 (c), the control section 2 displays an outgoing call operation window using the outgoing call history in the display section 5 (step S34). If the telephone number of the recipient of the call in the outgoing call history data is registered in the phone book data, the registration name corresponding to the telephone number is displayed in the display section 5 by the control section 2. In contrast, if the telephone number of the recipient of the call in the outgoing call history data is not registered in the phone book data, the telephone number is displayed in the display section 5.

Then, the control section 2 performs an outgoing call process that makes an outgoing call using the telephone number selected by the user from the telephone numbers displayed in the display section 5 as the telephone number of the call recipient (step S35). When the display section 2 ends the outgoing call process using the outgoing call history, the control section 2 also deletes the data item having the oldest outgoing call date and time in the outgoing call history data currently stored in the working memory 6 (step S30). The control section 2 stores an additional new outgoing call data element using the outgoing call history as its own outgoing call history data in the working memory 6 (step S31). Further, the control section 2 stores in the form of a time stamp the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the outgoing call, corresponding to the telephone number of the recipient of the call.

When the user presses the “HISTORY” button 4a and then the “INPUT CALL HISTORY” button 4c, the control section 2 determines that the user performs an outgoing call operation using the incoming call history (“YES” in step S26). The control section 2 accesses the incoming call history data stored in the working memory 6 (step S36). The control section 2 accesses the phone book data stored in the working memory 6 (step S37). As shown in FIG. 12 (b) and FIG. 12 (c), the control section 2 displays an outgoing call operation window using the incoming call history in the display section 5 (step S38). If the recipient's phone number in the incoming call history data is registered in the phone book data, the registration name corresponding to the phone number is displayed in the display section 5 by the control section 2. In contrast, if the phone number of the recipient of the call in the incoming call history data is not registered in the phone book data, the telephone number is displayed in the display section 5.

Then, the control section 2 performs an outgoing call process that performs an outgoing call using, as the telephone number of the call recipient, the telephone number selected by the user from the telephone numbers displayed in the display section 5 (step S39). When the control section 2 ends the outgoing call process using the incoming call history, the control section 2 also deletes the data item having the oldest outgoing call date and time in the outgoing call history data currently stored in the working memory 6 (step S30). The control section 2 stores an additional new outgoing call data element using the incoming call history as its own outgoing call history data in the working memory 6 (step S31). Further, the control section 2 stores in the form of a time stamp the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the outgoing call, corresponding to the telephone number of the recipient of the call.

When the user presses the “PHONE BOOK” button 4d, the control section 2 determines that the user performs an outgoing call operation using the phone book (“YES” in step S27). The control section 2 accesses the phone book data stored in the working memory 6 (step S40). As shown in FIG. 13 (b), the control section 2 displays an outgoing call operation window using the phone book in the display section 5 (step S41). Then, the control section 2 performs an outgoing call process that makes an outgoing call using the telephone number selected by the user from the telephone numbers displayed in the display section 5 as the telephone number of the call recipient (step S42). When the display section 2 completes the outgoing call process using the phone book, the control section 2 also deletes the data item having the oldest outgoing call date and time in the outgoing call history data currently stored in the working memory 6 (step S30). The control section 2 stores an additional new item of outgoing call data using the phone book as its own outgoing call history data in the working memory 6 (step S31). Further, the control section 2 stores in the form of a time stamp the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the outgoing call, corresponding to the telephone number of the recipient of the call.

When the control section 2 determines, using the communication section 3, that the cellular telephone 2 receives an incoming call from the cellular telephone network (“YES” in step S28), the control section 2 performs an incoming call process to notify of the incoming call (step S43). When the incoming call process is completed, the control section 2 deletes the data item having the oldest incoming call date and time in the incoming call history data currently stored in the working memory 6 (step S44). The control section 2 stores an additional new item of incoming call data representing this incoming call as its own incoming call history data in the working memory 6 (step S45).

Thus, when the control section 2 receives, via the Bluetooth communication section 3, the telephone number “09000000200” from the cellular telephone network as an incoming telephone number, the control section 2 further stores an incoming call history data element representing the telephone number “09000000200” as its own incoming call history data in working memory 6.

Thus, even if the wireless connection using PBAP is not made after the wireless connection using HFP in step S9, when a new incoming call process or a new outgoing call process occurs after step S9, the user’s own outgoing and incoming call history data is added and displayed to the user . As a result, there is no need to make simultaneous HFP and PBAP connections. After the wireless connection using the HFP in step S9, there is no need to terminate the wireless connection using the HFP and establish the wireless connection using the PBAP. Thus, this prevents essentially the separation of the cell phone 10 and the car navigation device 1, which constitute an independent telephone system.

Further, the following explains the process of displaying the history data of outgoing and incoming calls that were received wirelessly using PBAP, and the history data of outgoing and incoming calls generated in the outgoing and incoming call processes that occur after step S9.

In the state of the wireless connection using the HFP started in step S9, the cellular telephone 10 transmits the incoming telephone number to the car navigation device 1 when an incoming call is received. At this time, the date and time of the incoming call are not transmitted simultaneously. Thus, the control section 2 stores, in the form of a time stamp, the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the incoming call corresponding to the telephone number “09000000200”.

Thus, in FIG. 10 (b), the date and time of the incoming call of the newest telephone number “09000000200” is the time that the GPS device of the car navigation device 1 received, while the other dates and times of the incoming calls of the remaining four phone numbers are at times that the watch device of the cellular telephone 10 received. Further, when the user then performs an operation to display the incoming call history data, the control section 2 displays the display window in the display section 5, as shown but in FIG. 12 (c).

The above explains the following. The number of outgoing call history data elements or incoming call history data stored in the working memory 6 is less than the number of outgoing call history data elements or incoming call history data transferred automatically from the cellular telephone 10. A data item having an old outgoing date and time the call, or the old date and time of the incoming call, is deleted from the outgoing call history data or the incoming call history data transferred automatically from the cellular telephone 10. A data item having new The date and time of the outgoing call or the date and time of the incoming call are stored in working memory 6, preferably from the data of the history of the outgoing calls or the data of the history of the incoming calls transferred automatically from the cellular telephone 10. Conversely, when connected via a wireless connection using PBAP, the number of automatically transferred elements data can be set (five data elements in the present embodiment) by the car navigation device 1 to the cellular telephone 10. Thus, a data element having The new date and time of the outgoing call, or the date and time of the incoming call, can preferably be stored in the working memory 6.

In the above configuration, the following is explained in the car navigation device 1. When a new outgoing call process or a new incoming call process is performed, the oldest item of outgoing call history data or incoming call history data is deleted from the outgoing call history data or incoming call history data stored in the working memory 6. Conversely, from the user's point of view, since if there are requirements, control section 2 may perform another process, as shown in the following replacement process, which is necessary when a wireless connection using PBAP is painful. e is not satisfied after the step S9, as in the present embodiment.

Thus, when the time that the clock of the cell phone 10 counts is compared with the time that the GPS device of the car navigation device 1 receives, the time that the clock of the cell phone 10 counts sometimes has more errors and is less accurate than the time that Receives a GPS device. In addition, the time that the watch device of the cellular telephone 10 counts can be set by the user: thus, the time can be set by the user intentionally ahead of, or vice versa, with a lag for a predetermined period of time (for example, 10 minutes).

Thus, the following is assumed. The user temporarily sets the time on the cell phone 10 ahead of the set period of time; thus, the car navigation device 1 stores the set time in the working memory 6. In this state, reordering in order of time is applied to the outgoing call history data and the incoming call history data that were automatically transmitted from the cellphone 10, and the outgoing call history data and data Incoming call history of the car navigation device 1. Accordingly, outgoing call history data or incoming call history data received from a new process The ss of an outgoing call or a new incoming call process in the car navigation device 1, although they are the newest on the time axis, are displayed in lines in the list display window (for example, the second, third line) other than the top line, and are not displayed at the very top line. This leads to a mismatch of the time axis that the user has memorized and the time axis that is displayed by the display section 5, thereby causing the user to feel mismatched.

To avoid such a discrepancy, the control section 2 displays the outgoing call history data or the incoming call history data that was transferred automatically from the cell phone 10 by arranging them in order of time in lines other than the top line, while simultaneously displaying the new outgoing call history data or new data on the history of incoming calls of the car navigation device 1 itself, placing them on the very top line. This allows the display device to correspond to the time axis that the user has memorized, helping to prevent the user from feeling mismatched.

Further, when displaying outgoing call history data or incoming call history data that was automatically transmitted from the cellular telephone 10 in the order of dates and times, the control section 2 may not always need to rearrange the outgoing call history data or incoming call history data using the date and time. Thus, if the outgoing call history data or the incoming call history data has outgoing call or incoming call order data, then the outgoing call history data or the incoming call history data can be displayed based on the order of the outgoing calls or incoming calls.

In addition, the order data of outgoing calls or incoming calls may not be explicitly contained. The data can be transmitted in the form of a list shown in FIG. 3 (a), FIG. 4 (a), FIG. 5 (a) from the cell phone 10, and received by the car navigation device 1. In this case, the data can be displayed on based on the rule that a higher order corresponds to newer data. Thus, the cellular telephone 10 transmits data in a format in which the real order of outgoing calls or incoming calls is discernible in the car navigation device 1.

For example, in cell phone 10, an incoming call from Mr. A arriving at 12 hours zero minutes zero seconds (12:00:00) and an incoming call from Mr. B at 12 hours zero minutes (12:00:30) may have the same timestamps like twelve hours zero minutes (12:00) if the minutes are the final units of reference instead of seconds. Data having such timestamps is stored as incoming call history data in the cellular telephone 10. When receiving such data, the car navigation device 1 attempts to reorder the data in order of time, but cannot determine the order of time. Accordingly, it is required that the cellular telephone 10 assign data with data on the order of outgoing calls or incoming calls, or in the form of the above list. This allows the display device to correspond to the time axis that the user has memorized, helping to prevent the user from feeling mismatched.

In this case, the date and time data contained in the outgoing call history data or in the incoming call history data is processed as additional data, while the above data on the order of outgoing calls or incoming calls serve as the real order of outgoing calls or incoming calls. In addition, the cellphone 10 itself repeats the incoming call process and the outgoing call process independently without interacting with the car navigation device 1. Thus, the cellphone 10 can recognize the order of outgoing or incoming calls, thus processing the history of outgoing or incoming calls in accordance with the correct order. Accordingly, the cell phone 10 assigns the call data on the order of the outgoing calls or incoming calls without involving the date and time of the outgoing or incoming calls from the watch device of the cell phone 10 and transmits them to the car navigation device 1. After receiving them, the car navigation device 1 processes them to arrange the data history of outgoing or incoming calls based on data on the order of outgoing or incoming calls. Alternatively, without assigning order data to outgoing or incoming calls, cell phone 10 can prepare the above list by determining the real order and transmit them to car navigation device 1. Car navigation device 1 can process them to arrange them in real order of outgoing or incoming calls according to the above rule.

The above may correspond to the following case. Assume that the clock of the cell phone 10 can be set ahead or behind a certain time. When an outgoing or incoming call arises immediately after this, the outgoing or incoming call history data is displayed in real order, while the order of the dates and times attached to the outgoing or incoming call history data is different from the displayed order. Because of this, when such outgoing or incoming call history data is rebuilt based on the dates and times of the outgoing or incoming call history data by the car navigation device 1, the rebuilt data is displayed in an order different from the real order. Accordingly, to arrange the data in real order, you may need a technique for using data on the order of outgoing or incoming calls or a technique for using the list form to arrange data in a real outgoing or incoming order.

As a result, the control section 2 can display the data in the display section 5 in real order of the outgoing or incoming calls that have occurred in the cell phone 10. After performing such data management in the car navigation device 1, the following occurs. As described above, the outgoing call process can be performed using pressing the dial buttons of the car navigation device 1 using the outgoing call history, incoming call history or phone book data. In the outgoing call history data currently stored in the working memory 6, data that is the oldest or considered the oldest in the order of the outgoing call history data is deleted. The newest outgoing call data element, which indicates an outgoing call using the outgoing call history in the car navigation device 1 itself, is additionally stored as its own outgoing call history data in the working memory 6. In contrast, when a new incoming call process occurs, the control section 2 deletes data that is oldest or considered oldest in order of incoming call data in incoming call history data stored in working memory 6 in given point in time. The newest incoming call data element, which indicates an incoming call using its own incoming call history in the car navigation device 1, is additionally stored as its own incoming call history data in the working memory 6.

In the aforementioned outgoing call process or the incoming call process, the control section 2 stores, as a time stamp, the date and time obtained using the GPS device of the car navigation device 1 as the date and time of the outgoing call corresponding to the telephone number of the recipient of the call or the date and time of the incoming call corresponding to source phone number. This allows the display device to correspond to the time axis that the user has memorized, helping to prevent the user from feeling mismatched.

More specifically, in the case where there is a request to display all history data collecting outgoing call history data and incoming call history data, the control section 2 needs a predetermined sorting process compared to the case where only the above-mentioned outgoing call history data or data is displayed Incoming call history.

As mentioned above, the cell phone 10 can transmit incoming call history data or outgoing call history data so that the newest order can be recognized using the outgoing or incoming call order data on the real time axis. Alternatively, the cell phone 10 may transmit the data in a list without including order data. In such cases, the car navigation device 1 displays the data in an “as is” order, as mentioned above, regardless of the date and time of the outgoing call or the date and time of the incoming call. In the case of displaying only the history of incoming calls or the history of incoming calls, the data can be displayed in the order corresponding to the display order in the cell phone 10.

However, when displaying all history data, the following problems occur. The car navigation device 1 can reliably recognize the newest among outgoing calls or the newest among incoming calls; however, the car navigation device 1 cannot really recognize a newer among both of the newest calls. Accordingly, in the present embodiment, when displaying all the history data, the dates and times included in the outgoing call history data and the incoming call history data are compared with each other, and the newer is ultimately displayed as the newest. For example, with respect to five data elements of the history of incoming calls and five data elements of the history of outgoing calls, these ten data elements are displayed being re-sorted in the order of date and time. Thus, in most cases, outgoing call history data and incoming call history data can be displayed on the real time axis of the user. Conversely, when the timestamp function in cell phone 10 is accurate to “minute”, an incoming call from Mr A arrives at 12 hours zero minutes zero seconds (12:00:00) and zero thirty minutes is transmitted at 12 hours (12:00 : 30) an outgoing call to Mr. B may have the same timestamp as twelve hours zero minutes (12:00). The car navigation device 1, therefore, needs a predetermined reordering of the display of the outgoing call, processed as newer than the incoming call, and vice versa.

In addition, when the newest three-element order (AC) of incoming call history data received by the PBAP wireless connection can be recognized, as mentioned above, and, moreover, the newest outgoing call history data element (DF) order adopted wirelessly using PBAP, can be recognized, the dates and times of the outgoing call history data and the incoming call history data can be compared with each other as follows to perform reordering.

First, the dates and times of A and D are compared, and the newest is considered the first (for example, A). Then, the dates and times of B and D are compared, and the newest is considered the second (for example, B). Then the dates and times C and D are compared, and the newest is considered the third (for example, D). Then, the dates and times of C and E are compared, and the newest is considered the fourth (for example, B). Further, with respect to E and F, since E is the newest, the fifth becomes E and the sixth becomes F. When the dates and numbers being compared are identical, reordering is carried out in accordance with a predetermined rule in which an outgoing call takes precedence over an incoming call, or vice versa.

In addition, when transferring phone book data, the cell phone 10 needs to convert its own data format to the “vCard” format specified by the specification of the Bluetooth communication standard. Further, the phone book data is updated less frequently compared to the outgoing call history data and the incoming call history data. Thus, the control section 2 preferably receives the outgoing call history data and the incoming call history data and then receives the phone book data using the Bluetooth communication section 3 from the cell phone 10. In addition, the control section 2 receives the outgoing call history data and the incoming call history data via Bluetooth communication section 3 from cell phone 10; then, only when the user performs the specified operation using the operation section 4, the phone book data can be transmitted through the Bluetooth communication section 3 from the cell phone 10.

In addition, the user can indicate by selecting in the car navigation device 1 whether to transfer phone book data based on the user's operation or automatically, thereby performing the transfer process in accordance with the user's instructions. Provided that for automatic transmission it is indicated “do not transmit”, after establishing a wireless connection using the HFP in step S9, a non-automatic user operation may be performed to transmit only the phone book data. Accordingly, the wireless connection using the HFP in step S9 is interrupted by a non-automatic transmission operation and a wireless connection using PBAP is established. After the data transfer is completed, the wireless connection using the HFP with the cellular telephone 10 is again made, thereby switching to a state that allows making a telephone call using the speakerphone.

With the “do not transmit” setting, outgoing call history data and incoming call history data having a higher refresh rate can be received in a preferred manner compared to phone book data having a lower refresh rate. In addition, while no data format conversion is required for outgoing call history data or incoming call history data, data format conversion is required for phone book data. Accordingly, the outgoing call history data and the incoming call history data having a shorter transmission time can preferably be received with respect to the phone book data having a longer transmission time. The amount of data transferred can be reduced by transmitting only the outgoing call history data and the incoming call history data. As a result, the connection via the transmission protocol can be completed quickly and the connection by the following handsfree protocol can be completed quickly. Thus, the time before making a speakerphone phone call can be shortened when the cell phone appears in the car. Moreover, if necessary, you can choose whether to receive phone book data that requires a long transmission time and has a low refresh rate, which improves usability.

When phone book data is transferred using a user-defined data transfer operation if necessary, a connection using HFP is established automatically after the transfer is completed. When making an outgoing call using the phone book data, a hands-free phone call can be made, which improves usability. Further, when the phone book data is transmitted based on a non-automatic transfer operation, only the phone book data can be stored in the non-volatile storage memory 7. The stored data can be read from the storage memory 7 the next time the car navigation device 1 is turned on and used as phone book data.

In addition, the control section 2 can store outgoing call history data, incoming call history data and phone book data that were received from the cell phones 10 in the working memory 6 so that the data from each of the cell phones 10 is different from the others. In this case, the control section 2 associates the data stored in the working memory 6 with each cell phone 10, for example, as follows. When the control section 2 stores the outgoing call history data, the incoming call history data and the phone book data that were received from the cell phone 10 in the working memory 6, a communication key is generated based on the cell phone identifier and the device identifier, and the generated key is stored in the working memory 6 in connection with various data. More specifically, the cell phone identifier is uniquely assigned to the cell phone 10 and received from the cell phone 10, while the device identifier is uniquely assigned to the car navigation device 1. Upon receipt of the cell phone identifier from the cell phone 10, the control section 2 regenerates the communication key based on the received cell phone ID and device ID, and various data stored in the working memory 6 in association with the generated lyuchom connection.

Further, the HFP process is described in detail. The connection using HFP and PBAP in step S2 is controlled in accordance with the diagram shown in FIG. That is, when the control section 2 determines whether a connection has been established with the cellular telephone 10 located in the Bluetooth communication area, the control section 2 makes (starts) a wireless connection using the HFP (step S51). The control section 2 determines whether the cell phone 10 is in a telephone call state or not (step S52). More specifically, whether the cell phone 10 is in a phone call or in a standby state becomes known using a wireless connection using HFP. After receiving the state of the cellphone 10, the car navigation device 1 determines it in accordance with the received connection state. More specifically, step S51 corresponds to the processing in step S2.

When the control section 2 determines that the cellular telephone 10 is not in a telephone call state, namely, the cellular telephone 10 is in the idle state (“NO” in step S52), the established wireless connection using the HFP is terminated (terminated) (step S54). A wireless connection using PBAP is performed (step S55). That is, if the cellular telephone 10 is not in a telephone call state, the control section 2 immediately automatically terminates the established wireless connection using HFP and then automatically establishes a wireless connection using PBAP. Thus, the control section 2 induces the Bluetooth communication section 3 to receive the outgoing call history data, the incoming call history data and the phone book data transmitted from the cellular telephone 10.

Conversely, when the control section 2 determines that the cellular telephone 10 is in a telephone call state (“YES” in step S52), the control section 2 supports a wireless connection using HFP, assuming that a hands-free phone call can be made using the car navigation device 1. More specifically, whether a phone call is made is mainly dependent on cell phone 10. If a wireless connection using HFP was established when cell phone 10 is in and a telephone call, the received sound can be transmitted Bluetooth communication section 3 automatically or based on operation with a cellular telephone 10.

Then, the control section 2 determines whether the cell phone 10 has completed the telephone call (step S53). When it is determined that the cellular telephone 10 has completed the telephone call (“YES” in step S53), the wireless connection using the HFP is disconnected (terminated) (Step S54). A wireless connection is established using PBAP (Step S55). If the cell phone is in a phone call, the control section 2 terminates the wireless connection using the HFP after the telephone call is completed and then performs the wireless connection using the PBAP. After the user has completed the hands-free phone call, the control section 2 causes the Bluetooth communication section 3 to receive the outgoing call history data, the incoming call history data and the phone book data transmitted from the cellular telephone 10. More specifically, steps S52 and S53 correspond to the processing between steps S3 and S4.

Thus, when the cell phone 10 is connected to the car navigation device 1, it is determined whether the cell phone 10 is in a phone call state. If it is in a phone call state, switching to a wireless connection using PBAP prevents the cell phone 10 from being put into a hands-free phone call state. Thus, a wireless connection using HFP is supported and a wireless connection using PBAP is not made during a telephone call. When it is determined that the telephone call is completed, the wireless connection using HFP is terminated and the wireless connection using PBAP is completed. As a result, when the cell phone 10 is in a phone call state independently, it becomes possible to smoothly transfer the cell phone 10 to the hands-free phone call mode.

Further, the control section 2 can save the incoming call history data by distinguishing between the history of the answered incoming calls of the cellphone 10 and the history of the unanswered incoming calls (history of missed incoming calls) of the cellphone 10 from each other. In such cases, the following may be done. When the user presses the “HISTORY” button 4a and then the “Incoming call history” button 4c, the control section 2 determines that an outgoing call operation is being performed using the incoming call history. The control section 2 then accesses the incoming call history data stored in the working memory 6 and accesses the phone book data stored in the working memory 6. An outgoing call operation window is displayed in the display section 5, as shown in FIG. 16 (b ) and FIG. 16 (c). More specifically, the window displays, for each data item, either a graphic sign indicating an incoming call answered (a figure having a combination of a telephone receiver and an arrow), or a graphic sign indicating an incoming call (missed incoming call) to which there was no answer (a figure having a combination of a telephone receiver and an x).

The above explains the case when the control section 2 stores outgoing call history data, incoming call history data and phone book data that was transmitted from the cell phone 10 in the working memory 6, or a case where only the phone book data is stored in the storage memory 7. Conversely, the control section 2 can store outgoing call history data, incoming call history data and phone book data that were transmitted from the cellphone 10 in the storage memory 7. In this configuration, even if the power source of the device is turned off, the outgoing call history data, Incoming call history data and phone book data that have been stored in the storage memory will continue to be saved.

As explained above, the present embodiment may provide the car navigation device 1 of the present embodiment as follows. To reduce simultaneous connections using HFP and PBAP as much as possible, to achieve more reliable procedures, time-divided serial connections are performed in HFP and PBAP. Thus, it becomes possible to reliably make a stable connection with cell phones made by many manufacturers and compatible with wireless using HFP and wireless using PBAP. In addition, the process in the car navigation device 1 is uncomplicated; furthermore, it becomes possible to perform HFP and PBAP processing using a simple process.

In addition, during a wireless connection using HFP after PBAP, after terminating a wireless connection using PBAP, an outgoing call to a cellular telephone network or an incoming call from a cellular telephone network may be received. In such cases, in the outgoing call history data and the incoming call history data currently stored in the working memory, the data item having the oldest outgoing call date and time or the incoming call date and time is deleted and the outgoing call history data or history data incoming calls of the car navigation device 1 itself are stored in the working memory 6. Thus, whenever an outgoing call to a cellular telephone network or an incoming call from a cellular telephone network occurs, the latest data is Rhee outgoing calls or the most recent history data of incoming calls of the device can be stored.

In addition, in the connection state with the cell phones 10, after connecting using the HFP in step S2, it is determined whether the cell phone 10 is in a phone call state. When the cellular telephone 10 is in a telephone call state, a wireless connection using PBAP is performed after the telephone call is completed, and outgoing call history data, incoming call history data and phone book data are received from the cellular telephone 10. In this configuration, the speakerphone phone call can be performed without disrupting the transfer of outgoing call history data and incoming call history data from the cell phone 10.

Further, in the car navigation device 1, in a state of establishing Bluetooth connection with the cell phones 10, upon receiving from the cell phone 10, outgoing call history data and incoming call history data that were stored in the cell phone 10 before establishing the Bluetooth connection, the car navigation device 1 saves the received outgoing call history data and incoming call history data in working memory 6 equally with its own outgoing call history data and incoming call history data a of the navigation device 1. The outgoing call operation is then possible using the outgoing call history data and the incoming call history data stored in the working memory 6. In this configuration, along with the outgoing call by selecting the desired phone number from the outgoing call history data or data the history of incoming calls received automatically from the cell phone 10, an outgoing call can be made by selecting the desired phone number from the data history and outgoing call history data or incoming calls belonging to the car navigation device 1. Thus, the improved usability.

In addition, in the case of a request to display outgoing call history data or incoming call history data, if the same phone number is presented as the phone number of the recipient of the call or the source phone number stored in the working memory 6 as outgoing call history data or incoming call history data, The login name corresponding to the phone number is displayed. In such a configuration, the outgoing call history data or the incoming call history data received from the cellular telephone 10 can be displayed using the registration name stored in the phone book data.

In addition, each time an outgoing call process is performed, the outgoing call history data of the car navigation device 1 itself is displayed as a data item having the newest outgoing call date and time in the displayed outgoing call history data list. Conversely, each time an incoming call process is performed, the incoming call history data of the car navigation device 1 itself is displayed as a data item having the newest date and time in the displayed list of incoming call history data. Such a configuration may correspond to the following case when the date and time received by the cellular telephone 10 are inconsistent with the date and time received by the car navigation device 1, and then the date and time of the outgoing call or the date and time of the incoming call, which are automatically transmitted from cell phone 10 are not consistent with the date and time of the outgoing call or the date and time of the incoming call of the car navigation device 1 on the time axis. Thus, the user can be protected from a sense of inconsistency arising from the inconsistency of the date and time between the cell phone 10 and the car navigation device 1.

In addition, outgoing call history data, incoming call history data and phone book data can be stored separately for each cell phone 10 in the working memory 6. With this configuration, outgoing call history data, incoming call history data and phone book data can be managed for each cell phone 10. In addition, outgoing call history data, incoming call history data and phone book data may be stored separately for each cell phone 10 in the storage memory 7. With this configuration, as soon as the device’s power supply is turned on, there is no need to receive phonebook data from the cellphone 10. The user can quickly use the stored phonebook data as corresponding to the cellphone 10 available to the user, significantly improving usability at the time of use phone book features.

Moreover, when outgoing call history data, incoming call history data and missed incoming call history data are displayed together as all history data, for outgoing call history data having an identical (overlapping) phone number of the call recipient, only the data item having the most The new date and time of the outgoing call. This configuration allows you to increase the history information.

Outgoing call history data, incoming call history data and phone book data that were received from the cellular telephone 10 can be stored in the working memory 6 or in the storage memory 7 at the same time. Thus, the storage memory 7 can be used as archive memory.

The number of outgoing call history data elements or incoming call history data stored in the working memory 6 may be one, respectively. In such cases, when an outgoing call process or an incoming call process occurs in the car navigation device 1, the outgoing call history data and the incoming call history data that were received via the wireless connection using PBAP are always deleted.

In addition, in the car navigation device 1, although a plurality of outgoing call history data items or incoming call history data is displayed at the same time, each data item can be displayed. In such cases, for example, the newest data item is displayed first, and then the next most recent data item can be displayed using operation section 4.

The number of outgoing call history data elements or incoming call history data stored in the working memory 6 may be one, respectively. In such cases, when an outgoing call process or an incoming call process occurs in the car navigation device 1, the outgoing call history data and the incoming call history data that were received via the wireless connection using PBAP are always deleted.

In the state of establishing a Bluetooth connection between the cellular telephone 10 and the car navigation device 1, without limiting the configuration in which the outgoing call history data and the incoming call history data are transmitted automatically, they can be transmitted provided that the user controls the car navigation device 1 or the cell phone 10.

In cases where the control section 2 stores outgoing call history data, incoming call history data and phone book data that were received from the cellular telephone 10 in the working memory 6, so that the data for each of the cellular telephones 10 is different from the others, without configuration limitation for associating data stored in the working memory 6 with the cell phone 10

In the disconnection step, the connection is disconnected using the transmission protocol after receiving incoming call history data. In the connection step using the speakerphone, a connection is automatically established using the speakerphone protocol to make a telephone call using the speakerphone using a cell phone after disconnecting in the disconnection step.

Thus, in accordance with the present description, after the data is transmitted by communication using the transmission protocol, the communication using the transmission protocol is disconnected, and then communication using the hands-free protocol is performed. As a result, there is no need to make a connection using the transmission protocol and the hands-free protocol at the same time. Since the processing volume in the car navigation device can be reduced, compatibility with various types of cell phones can be improved.

In addition, as another aspect, the means or control unit includes means or a unit for determining whether a cell phone is making a phone call by making an initial connection using the speakerphone to make a phone call using the speakerphone using a cell phone before communicating using the transfer protocol . When determining by the means or unit of determining that a telephone call is being made, the means or control unit supports initial communication using the speakerphone protocol. When determining by the means or unit for determining that the telephone call is completed, the means or control unit establishes communication using the transfer protocol after disconnecting the supported connection using the hands-free protocol.

The means or unit for determining whether a cell phone is making a phone call. The tool or unit maintains the connection supports the initial connection using the hands-free protocol, when it is using the means or node definition determines that a telephone call. When determining by the means or unit for determining that the telephone call is completed, the means or control unit establishes communication using the transmission protocol after disconnecting the supported initial communication using the hands-free protocol.

In addition, as another aspect, the means or control unit includes means or a unit for determining whether a cell phone is making a phone call by making an initial call using the speakerphone to make a phone call using the speakerphone using a cell phone before communicating using the protocol transmission. When determining by the means or unit of determining that a telephone call is being made, the means or control unit supports initial communication using the speakerphone protocol. When determining by the means or unit for determining that the telephone call is completed, the means or control unit establishes a communication connection using the transmission protocol after disconnecting the supported connection using the hands-free protocol.

In addition, as another aspect, the hands-free initial connection tool or unit automatically initiates the initial use of the hands-free protocol to make a phone call using the speakerphone using a cell phone before communicating using the transfer protocol. The means or unit for determining whether a cell phone is making a phone call. The communication tool or unit supports wireless communication using the hands-free protocol when it determines by means of the determination tool or unit that a telephone call is being made. When determining by the means or unit for determining that the telephone call is completed, the means or control unit of the transmission protocol establishes a communication connection using the transmission protocol after disconnecting the supported initial communication using the speakerphone.

In addition, as another aspect, the speakerphone initial communication facility or unit automatically initiates initial communication using the speakerphone to make a telephone call using the speakerphone using a cell phone before communicating using the transfer protocol. The means or unit for determining whether a cell phone is making a phone call. The communication tool or unit maintains initial communication using the hands-free protocol when it determines by means of the determination tool or unit that a telephone call is being made. When determining by the means or unit for determining that the telephone call is completed, the means or control unit of the transmission protocol establishes a communication connection using the transmission protocol after disconnecting the supported initial communication using the speakerphone.

In addition, as another aspect, in the initial connection stage of the hands-free protocol, the initial connection is first automatically established using the hands-free protocol for making a telephone call using the speakerphone using a cellular telephone before the connection step of the transmission protocol. At the determination stage, it is determined whether the cellular telephone makes a telephone call using the hands-free protocol established at the initial connection stage of the hands-free protocol, and at the maintenance stage, initial communication is performed using the hands-free protocol, when it is determined at the determination stage, that a phone call is being made. At the stage of disconnecting the handsfree protocol connection, the initial connection is disconnected using the hands-free protocol supported in the supporting step, when it is determined in the determining step that the telephone call is completed. After disconnecting the connection using the hands-free protocol, at the stage of disconnecting the connection using the hands-free protocol, the step of establishing a connection using the transmission protocol is performed.

In addition, as another aspect, the initial connection step by the hands-free protocol first automatically establishes the initial connection using the hands-free protocol to make a telephone call using the speakerphone using the cell phone before the connection step of the transmission protocol. In the determination step, it is determined whether the cell phone is making a telephone call using the initial communication using the speakerphone established at the initial connection stage of the speakerphone. At the maintenance stage, initial communication is maintained using the hands-free protocol, when it is determined at the determination stage that a telephone call is being made. At the stage of disconnecting the handsfree protocol connection, the initial connection is disconnected using the hands-free protocol supported in the supporting step, when it is determined in the determining step that the telephone call is completed. After disconnecting the connection using the hands-free protocol, at the stage of disconnecting the connection using the hands-free protocol, the step of establishing a connection using the transmission protocol is performed.

Thus, before communicating using the transmission protocol, the speakerphone is communicated and it is determined whether the cell phone is in a telephone call state. If it is in a telephone call state, then communication using the hands-free protocol is supported. On the contrary, when it is determined that he is not in a state of a telephone call, that is, when the telephone call is completed, the connection using the speakerphone is disconnected. Then, communication is established using the transmission protocol. Accordingly, when a cell phone that is independently in a phone call is connected to the car speakerphone, a connection using the transfer protocol is not established. Thus, it becomes possible to change the telephone call, independently made by the cellular telephone, to the telephone call using the speakerphone using the car speakerphone.

In addition, as another aspect, the means or display unit displays outgoing call history data. The operating tool or unit executes the outgoing call instructions on the cell phone. The display control tool or unit causes the display tool or display unit to display its own outgoing call history data, indicating the phone number of the recipient of the call in the outgoing call instruction as newer in the outgoing call date and time than the outgoing call history data when the request to display outgoing call history data calls occurs after the execution of an outgoing call instruction by an operating tool or unit in a connected state using the speakerphone for making a hands-free phone call with a cell phone after disconnecting the communication using the transfer protocol.

In addition, as another aspect, the display tool or unit displays incoming call history data. The display control means or unit receives the telephone number of the telephone call source, which is notified via communication using the hands-free protocol, as new incoming call history data when the cell phone receives a new incoming call in the communication state using the hands-free protocol to establish a hands-free phone call communication by the cellular telephone after disconnecting the communication using the transmission protocol and causes the display means or unit to display new data Rhee incoming call as a newer date and time of the incoming call is compared with the data of the history of incoming calls when a request to display the new incoming call history data occurs after receiving the incoming call history data.

In this case, after the transfer of outgoing call history data and incoming call history data made by communication using the transfer protocol, there is a transition to communication using the hands-free protocol. This makes it impossible to receive outgoing call history data or incoming call history data using the transfer protocol. So in the present case, it should be noted that new outgoing call history data or new incoming call history data can be obtained by the car speakerphone. Further, new outgoing call history data or new incoming call history data is displayed as a newer data item when data is received over the transmission protocol. Thus, it becomes possible to display history data in the order of real user outgoing calls and incoming calls.

In addition, as another aspect, outgoing call history data is transmitted from the cell phone in a format such that the order of the outgoing calls is identifiable; and the display control means or unit causes the display means or unit to display the outgoing call history data in the order of the outgoing calls in accordance with the format instead of using the received outgoing call date and time data to determine the display order.

In addition, as another aspect, incoming call history data is transmitted from the cell phone in a format such that the order of the incoming calls is identifiable; and the display control means or unit causes the display means or unit to display the incoming call history data in the incoming call order in accordance with the format instead of using the received incoming call date and time data to determine the display order.

More specifically, the outgoing call history data and the incoming call history data received by the transmission protocol comprise data on the date and time of the outgoing call and data on the date and time of the incoming call. If such date and time are used to reorder the order, then it may differ from the actual order of outgoing calls and incoming calls. Thus, when the outgoing call history data and the incoming call history data are transmitted in a format that can identify the real order of the dates and times of the outgoing calls and the dates and times of the incoming calls, despite the fact that the car speakerphone receives the date and the time of the outgoing call and data on the date and time of the incoming call, the car speakerphone displays the data of the history of the outgoing calls and the data of the history of the incoming calls in accordance with the identified form obscenities without using accepted data about the date and time. This allows the car speakerphone to display outgoing call history data and incoming call history data in accordance with the actual order of outgoing calls or incoming calls.

In addition, as another aspect, the phone book transfer setting tool or block establishes confirmation or rejection of the phone book data transfer. The data transfer destination means or unit transmits only the outgoing call history data and the incoming call history data when the means or the phone book transfer setting unit does not establish a transfer negation.

In the context of this document, outgoing call history data and incoming call history data generally have less data than phone book data and are used more often than phone book data. Thus, setting up phone book data transmission becomes possible. When the setting is set so as not to transfer phone book data, only the data of the history of outgoing calls and the data of the history of incoming calls are transmitted, thus allowing to reduce the transmitted amount of data. As a result, communication using the transmission protocol can be performed quickly, thus allowing communication using the subsequent hands-free protocol at an early stage. Thus, the time before making a speakerphone phone call can be reduced when the cell phone is brought into the car.

In addition, as another aspect, the means or block for the manual execution of the transmission protocol receives only the phone book data by manually executing the transmission protocol. In a state where wireless communication is performed using the hands-free protocol using the means or control unit of the hands-free protocol, communication using the transmission protocol is performed after disconnecting the communication using the hands-free protocol, when the execution of the transmission protocol is requested by the means or node of the manual execution of the transmission protocol ; the means or control unit of the handsfree protocol communicates using the handsfree protocol automatically after completion of the transfer of phone book data.

Thus, the transfer of phone book data can be ensured by a non-automatic user operation as necessary, thereby improving usability. Hands-free calling is automatically performed after the transfer is completed; thus, when making an outgoing call using the phone book data, it may be possible to make a hands-free phone call, which improves usability.

Although specific embodiments of the invention have been described above, it should be understood that they do not imply a limitation of the invention to the particular form disclosed, but, on the contrary, the invention covers all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claims.
