Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to elements of each drawing, it should be noted that the same elements have the same numerals as possible even if they are indicated on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, a preferred embodiment of the present invention will be described below, but the technical idea of the present invention is not limited or limited thereto, and may be modified and variously implemented by a person skilled in the art.

When a mobile phone that supports H/U (Head Unit) and PBAP (Phone Book Access Profile) is connected via BT (BlueTooth), the phone book data of the mobile phone is downloaded to H/U at the request of H/U. However, if there is a problem with the downloaded phonebook due to phone compatibility issues, etc., there is no way to recover.

BT phonebook download failures or errors due to phone compatibility issues are as follows.

First, phonebook data is specified to follow the VCARD format, but it is not included in BT certification, so there is no mandatory standard.

Second, the logic and performance for VCARD creation are different for each phone.

Third, there is a case where the PBAP connection is terminated while downloading the phonebook due to a BT connection error.

Fourth, a case occurs where the number of phonebook data transmitted from the mobile phone and the number of received VCARD data are different due to a data error during transmission.

The present invention informs the user that there is a problem with the downloaded data when the phonebook download using BT fails or there is a problem with the phonebook data downloaded using BT due to a phone compatibility issue, and Wi-Fi Direct for phonebook data recovery ( WIFI Direct) allows you to recover phonebook data by downloading phonebooks. Hereinafter, it will be described with reference to FIG. 1.

1 is a conceptual diagram schematically showing a phonebook download system according to an embodiment of the present invention.

The phonebook download system 100 includes a phone 110 and a head unit H/U 120.

When there is a request for phonebook download, the head unit 120 performs a function of connecting with the phone 110 using a PBAP (①).

The head unit 120 performs a function of determining whether the number of phonebook data stored in the second phonebook database 123 matches the number of phonebook data stored in the first phonebook database 111 (②).

When the head unit 120 is connected to the phone 110, the number of phonebook data stored in the second phonebook database 123 is calculated. Thereafter, the head unit 120 checks the number of phonebook data stored in the first phonebook database 111 through the phone 110. Thereafter, the head unit 120 compares the number of phonebook data stored in the second phonebook database 123 with the number of phonebook data stored in the first phonebook database 111 to determine whether they coincide with each other.

If it is determined that the number of phonebook data stored in the second phonebook database 123 does not match the number of phonebook data stored in the first phonebook database 111, the head unit 120 Performs the function of downloading data (③).

The first VCARD format processing unit 112 detects phonebook data stored in the first phonebook database 111 and converts it into a VCARD format. Thereafter, the first VCARD format processing unit 112 transmits the phonebook data converted to the VCARD format to the head unit 120. Thereafter, the second VCARD format processing unit 121 stores the received phonebook data in the second phonebook database 123.

When the phonebook data is downloaded from the phone 110, the head unit 120 performs a function of checking the integrity of the phonebook data.

The integrity check of the phonebook data is preferably performed before the second VCARD format processing unit 121 stores the phonebook data in the second phonebook database 123, but may be performed after that.

The head unit 120 performs a function of restoring the phonebook data when it is determined that the phonebook data is invalid as a result of checking the integrity of the phonebook data.

When the phonebook data is re-requested from the head unit 120, the first TXT/CSV format processing unit 113 detects the phonebook data stored in the first phonebook database 111 and converts it into a TXT format or a CSV format. Thereafter, the first TXT/CSV format processing unit 113 transmits the phonebook data converted to the TXT/CSV format to the head unit 120. Thereafter, the second TXT/CSV format processing unit 122 restores the previously received phonebook data of the VCARD format by using the received phonebook data, that is, the phonebook data of the TXT/CSV format.

2 is a flowchart illustrating a method of operating the phonebook download system according to the first embodiment of the present invention. Hereinafter, a BT phonebook data validity check and pop-up display scenario will be described with reference to FIGS. 1 and 2.

In this embodiment, the phone 110 is installed with a phonebook download application for WIFI Direct.

First, the phone 110 and the head unit 120 are connected using BT and PBAP (S205).

Thereafter, the head unit 120 interworks with the phone 110 to request and check the total number of phonebook data (S210).

If it is confirmed that the number of phonebook data does not match each other, the head unit 120 requests the phonebook data to be downloaded to the phone 110 (S215).

When the phonebook data is downloaded to the head unit 120, the head unit 120 parses the phonebook data using a V-card parser (S220).

Thereafter, the head unit 120 checks the validity of the phonebook data (S225 and S230). In the present embodiment, the method of checking the validity of the phonebook data by the head unit 120 includes a method of checking whether the phonebook data conforms to the VCARD format and includes essential items, the total number of requested phonebook data and the actual downloaded and parsed VCARD. There is a method of checking whether the number of data matches. In the present embodiment, any one of the former and the latter may be performed first, but in the following description, it will be described that the latter is performed first.

First, it is checked whether the total number of phonebook data requested by the head unit 120 and the number of actual downloaded and parsed VCARD data match (S225).

If it is determined that the total number of phonebook data and the number of parsed VCARDs match, the head unit 120 checks whether the phonebook data conforms to the VCARD format and includes essential items (S230).

The head unit 120 checks the following for this.

ex) BEGIN:VCARD

VERSION:2.1

FN;CHARSET=UTF-8:Masatani Aidan

N;CHARSET=UTF-8:Masatani;Aidan;;;

TEL;TYPE=CELL:12488770072

TEL;TYPE=HOME:514376972

TEL;TYPE=WORK:15659987846

TEL;TYPE=WORK:425472372

END:VCARD

The downloaded phonebook data must contain characters such as BEGIN:VCARD, END:VCARD, VERSION, FN, N, TEL, etc., which are mandatory items in VCARD format.

When it is determined that the phonebook data conforms to the VCARD format and includes essential items, the head unit 120 stores the phonebook data in the second phonebook database 123 (S235).

On the other hand, if it is determined that the total number of phonebook data and the number of parsed VCARDs do not match in step S225, or if it is determined in step S230 that the phonebook data does not include VCARD essential items (that is, if it is determined that VCARD essential items are lost), The head unit 120 determines that there is a problem with the validity of the phonebook data downloaded to the phone 110.

Therefore, in this case, the head unit 120 displays an error message for the phonebook data in a pop-up (S240), and newly downloads the phonebook data using WiFi Direct (S245). Thereafter, the head unit 120 restores the previously downloaded phonebook data by using the newly downloaded phonebook data, or discards the previously downloaded phonebook data and registers the newly downloaded phonebook data. In the case of recovering the phonebook data, the head unit 120 displays this fact in a pop-up (S250).

3 is a flowchart illustrating a method of operating the phonebook download system when the phonebook download cannot be completed using BT according to the first embodiment of the present invention. Hereinafter, a WIFI Direct phonebook download scenario proposed by the present invention will be described with reference to FIG. 3.

First, it is checked whether the phone 110 and H/U 120 support WIFI Direct, and if WIFI Direct is supported, a WIFI Direct connection is made (S305, S310). During BT connection, the phone 110 and H/U 120 refer to the BT Mac address to find and connect a device to be connected via Wi-Fi Direct.

After that, the phone 110 directly queries the phonebook DB information. Thereafter, the phone 110 directly reads the phonebook data from the DB and configures the phonebook data in the form of TXT/CSV (S315).

Thereafter, the phone 110 transmits the phonebook data to the H/U 120 through WIFI Direct (S320).

Thereafter, the H/U 120 sorts the phonebook data received through WIFI Direct by name (S325, S330).

Thereafter, the H/U 120 compares the BT phone book data and the WIFI phone book data, adds only the lost data (S335), and stores the data in the internal memory of the H/U 120 (S340).

Thereafter, the H/U 120 displays the updated phonebook data of the internal memory on the screen.

The advantages of the phonebook downloading method using WIFI Direct described with reference to FIG. 3 are summarized as follows.

First, phonebook data is specified to follow the VCARD format, but the internal data composition is different for each mobile phone. That is, there is no mandatory standard for the VCARD format, and the VCARD configuration is not included in BT certification. The present invention can prevent data loss due to a VCARD parser error inside the H/U since the mobile phone and the H/U transmit and receive data in a preset format (ex. CSV, TXT, etc.) not in the VCARD format.

Second, the logic and performance for VCARD creation differs for each phone. The present invention does not use VCARD that affects performance.

Third, there may be a case where the PBAP connection is terminated while downloading the phonebook due to a BT connection error. Since the present invention uses a WIFI connection independent of the BT connection, data received through the WIFI can be restored when the BT connection is disconnected and data is not received.

Fourth, the number of phonebook data transmitted from the mobile phone and the number of received VCARD data may be different due to an error during data transmission. In the present invention, when data is lost due to a BT interface error, it is possible to recover data received through WIFI.

Fifth, it takes a lot of time to update the DB by converting the VCARD received from the phone in H/U. The present invention does not use VCARD that affects performance, so there is no need for a process of converting VCARD to DB.

Sixth, incorrect phonebook information may come over, and an incorrect number of phonebooks are downloaded. The present invention does not exchange phonebook information before downloading the phonebook, and directly reads the phonebook DB from the phone and transmits it in the form of TXT or CSV.

4 is a flowchart illustrating a method of operating a phonebook download system according to a second embodiment of the present invention.

First, the head unit (H/U) 120 drives the BT mode (S405), and then the phone 110 drives the BT mode (S410). Steps S405 and S410 may be sequentially performed as described above, but may be performed simultaneously or may be performed before step S405.

Thereafter, the head unit 120 and the phone 110 perform pairing (S415).

Thereafter, the head unit 120 and the phone 110 connect profiles such as A2DP, HFP, and AVRCP (S420).

Thereafter, the head unit 120 and the phone 110 perform PBAP connection (S425).

Thereafter, the head unit 120 downloads the phonebook data from the phone 110 (S430). The head unit 120 exchanges the phonebook information of the phone 110 and then downloads the phonebook data.

Thereafter, the head unit 120 completes downloading the phonebook data from the phone 110 and displays it through the AVN system (S435).

However, if there is a problem with the BT phonebook due to a phone compatibility issue, there is no way to recover the phonebook. A solution to this will be described below with reference to FIG. 5.

5 is a flowchart illustrating a method of operating a phonebook download system when a phonebook download cannot be completed using BT according to a second embodiment of the present invention.

First, the head unit (H/U; 120) connects WIFI Direct after Power On (S505). Thereafter, the phone 110 connects the WIFI Direct after Power On (S510). In the present invention, step S505 may be performed first, and then step S510 may be performed later. However, the present invention is not limited thereto, and steps S505 and S510 may be performed simultaneously or step S510 may be performed first.

Thereafter, the phone 110 reads the phonebook DB and stores it in the form of a CSV/TXT file (S515).

Thereafter, the phone 110 transmits the phonebook data in the form of a CSV/TXT file to the head unit 120 using WIFI Direct (S520).

Thereafter, the head unit 120 compares the phonebook data transmitted through WIFI Direct with the BT phonebook data and performs a validity check (S525).

If the BT phonebook data is different from the phonebook data transmitted through WIFI Direct, the head unit 120 performs an update with the phonebook data transmitted through WIFI Direct (S530).

Hereinafter, a method of checking the validity between the phonebook DB and the BT phonebook DB delivered through WIFI will be described in more detail.

This method proceeds in the order of the following numbers, and replaces the BT phonebook DB with the WIFI phonebook DB at the stage where the problem occurs. After that, the sub-step no longer proceeds.

① Read the total number of WIFI phonebook DBs received through WIFI Direct and compare with the total number of BT DBs. If the total number is different, it is determined that there is a problem with the data of the BT phonebook DB, and the phonebook is updated with the WIFI phonebook DB.

② If the data size of the WIFI phonebook DB is compared with the data size of the BT phonebook DB, if the data size is different, it is determined that there is a problem with the data of the BT phonebook DB and the phonebook is updated with the WIFI phonebook DB.

③ Query the data of the WIFI phonebook DB one by one and compare it with the BT phonebook data DB by record unit. As soon as a record with a problem exists, it is determined that there is a problem in the data of the BT phonebook DB, and the phonebook is updated with the WIFI phonebook DB, and the record is not checked afterwards.
