The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0043] The technical solutions protected by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0044] Referring to Figure 1 A flowchart of a Bluetooth phone contact synchronization method provided by the embodiments of the present application is shown in the figure. The flow of the method is described as follows: S101: Establish a PBAP connection between a Bluetooth phone APP in a client and a server, and send an information synchronization request to the server based on the PBAP connection, the information synchronization request including a contact information request and a call record information request; S102: Receive a plurality of encapsulated contact information continuously transmitted by the server in response to the contact information request, and decompress the plurality of encapsulated contact information; S103: Call the decompressed contact information to the Bluetooth phone APP of the client in turn, and update the display of the contact information.

[0045] In a preferred embodiment, taking the client as a vehicle and the server as a mobile phone as an example, first, the mobile phone and the vehicle are connected through the Bluetooth framework, then the Bluetooth phone APP in the vehicle mobilizes the Bluetooth framework to send a PBAP connection instruction to the mobile phone, so that the mobile phone and the Bluetooth phone APP establish a PBAP connection, and direct communication between the mobile phone and the Bluetooth phone APP is realized based on the PBAP connection, and the information synchronization request includes a contact information request, a call record information request, etc.; then, the mobile phone packs and encapsulates the contact information stored in the mobile phone memory according to the received contact information request, obtains a plurality of encapsulated contact information, and transmits the plurality of encapsulated contact information into the Bluetooth phone APP through the Bluetooth framework one by one, the Bluetooth phone APP decompresses the plurality of encapsulated contact information and controls the Bluetooth phone APP of the vehicle to receive the decompressed contact information and update the display of the contact information through the second callback interface of the Bluetooth framework; the second callback interface is a callback interface for single contact information transmission, that is, a callback interface for transmitting one encapsulated contact information at a time, through the second callback interface, the contact information in the mobile phone can be transmitted to the Bluetooth phone APP in batches, and the display in the Bluetooth phone APP can be updated immediately after transmission, without waiting for all the contact information to be synchronized to the Bluetooth phone APP before updating the display, thereby reducing the user's waiting time for updating the contact information and improving the user experience.

[0046] S104: when the contact information synchronization is completed, receiving a plurality of encapsulated call record information continuously transmitted by the server in response to the call record information request, and decompressing the plurality of encapsulated call record information; S105: calling the decompressed call record information to the Bluetooth phone APP of the client one by one, and updating the display of the call record information; at the same time, after the call record information is synchronized, the Bluetooth phone APP sends a PBAP connection disconnection instruction to disconnect the PBAP connection between the Bluetooth phone APP and the server.

[0047] In a preferred embodiment, still taking the example of the client being a vehicle and the server being a mobile phone, when all the contacts in the mobile phone are completely synchronized to the Bluetooth phone APP, the mobile phone will request the call record stored in the mobile phone memory to be packaged and encapsulated in turn according to the received call record information, obtain a plurality of encapsulated call record information, and transmit the plurality of encapsulated call record information into the Bluetooth phone APP one by one. The Bluetooth phone APP decompresses the plurality of encapsulated contact information and controls the Bluetooth phone APP of the vehicle to receive the decompressed encapsulated call record information and update the display of the encapsulated call record information in turn through the third callback interface of the Bluetooth framework. The third callback interface is a callback interface for single call record information transmission, that is, a callback interface for transmitting one encapsulated call record information at a time. Through the third callback interface, the call records in the mobile phone can be transmitted to the Bluetooth phone APP in batches, and the display can be updated immediately after transmission, without waiting for all the call records to be synchronized to the Bluetooth phone APP before updating the display, thereby reducing the time for the user to wait for the call records to be updated and improving the user experience. When all the call records in the mobile phone are completely synchronized to the Bluetooth phone APP, the Bluetooth phone APP of the vehicle sends a PBAP connection disconnection instruction to disconnect the PBAP connection between the Bluetooth phone APP and the server. The Bluetooth phone APP will close the synchronization state, avoiding the problem that the Bluetooth phone APP is always in a synchronization state due to the inability of the Bluetooth framework to disconnect the connection in the prior art, and reducing the negative impact on the user experience.

[0048] In a preferred embodiment, the call records include missed call records, received call records, and outgoing call records. After updating one type of call record each time, the third callback interface of the Bluetooth framework needs to be called again to ensure the synchronization update and display of the Bluetooth phone APP.

[0049] Optionally, after sending the information synchronization request to the server based on the PBAP connection, the method further includes calling the first callback interface to make the Bluetooth phone APP perform the synchronization of the contact information. The first interface is a callback interface for the start of the synchronization of the Bluetooth phone APP in the client.

[0050] In a preferred embodiment, the callback interface on Contact Callback Start is called to call the start of the contact. The start of the contact operation forces the Bluetooth phone APP to perform the start of the contact download, which is equivalent to notifying the Bluetooth phone APP of the start of the contact download, making the Bluetooth phone APP in a synchronization preparation state, enabling the Bluetooth phone APP to quickly receive the decompressed contact information transmitted by the Bluetooth framework, and reducing the response time of the Bluetooth phone APP.

[0051] Optionally, the receiving the plurality of encapsulated contact information continuously transmitted by the server in response to the contact information request comprises: determining, by the server, the number of contacts in the server according to the contact information request; when the number of contacts exceeds a preset contact threshold, packaging, by the server, the contacts in the server based on the preset contact threshold, and encapsulating the packaged contacts to obtain the plurality of encapsulated contact information; and continuously transmitting, by the server, the plurality of encapsulated contact information to the client, and sequentially receiving, by the client, the plurality of encapsulated contact information.

[0052] In a preferred embodiment, still taking the client as a vehicle and the server as a mobile phone as an example, and taking the preset contact threshold as 200, since the number of contacts stored in the mobile phone can be large, one-time transmission can cause large delay and slow update display of the Bluetooth phone APP, therefore, the mobile phone determines the number of contacts in the mobile phone according to the contact information request; when the number of contacts exceeds 200, the mobile phone packages the contacts in the mobile phone according to 200 contacts as a group, taking the number of contacts in the mobile phone as 1100 as an example, the contacts in the mobile phone are packaged into five contact data packets, and five encapsulated contact information are obtained by encapsulating the five contact data packets, then the mobile phone continuously transmits the five encapsulated contact information to the vehicle, the Bluetooth phone APP in the vehicle sequentially receives the five encapsulated contact information by calling the Bluetooth framework, and the contact information is transmitted in batches, which facilitates subsequent rapid display on the Bluetooth phone APP, and there is no need to wait for all the contacts to be transmitted to the Bluetooth phone APP before updating and displaying, thereby reducing the user waiting time for updating the contacts and improving the user experience.

[0053] Optionally, the encapsulating the packaged contacts to obtain the plurality of encapsulated contact information comprises: encapsulating the packaged contacts in a vcard data format to obtain the plurality of encapsulated contact information.

[0054] In a preferred embodiment, since the vcard defines an organization method of personal information, and can be used for transmission and exchange of personal information, the application encapsulates the contacts in a vcard data format, the vcard uses fields to describe a piece of information of a person, such as a TEL field representing a telephone number, and a parameter WORK representing a unit telephone number. The vcard adopts a line-oriented organization form, and each line represents a complete piece of information except for multiple lines in the field value, and the vcard data format can better reflect the information characteristics of the contacts, and can quickly and effectively display the contact information when updating and displaying the Bluetooth phone APP.

[0055] Optionally, the receiving the plurality of encapsulated call record information continuously transmitted by the server in response to the call record information request comprises: determining, by the server, the number of call records in the server according to the call record information request; when the number of call records exceeds a preset call record threshold, the server packs the call records in the server based on the preset call record threshold, encapsulates the packed call records to obtain a plurality of encapsulated call record information; and the server continuously transmits the plurality of encapsulated call record information to the client, and the client receives the plurality of encapsulated call record information in sequence.

[0056] In a preferred embodiment, still taking the client as a vehicle and the server as a mobile phone as an example, taking the call record as a missed call record and the preset call record threshold as 150 as an example, since the number of missed call records stored in the mobile phone can be large, one-time transmission can cause large delay and slow update display of the Bluetooth phone APP, therefore, the mobile phone determines the number of missed call records in the mobile phone according to the call record information request; when the number of missed call records exceeds 150, the mobile phone packs the missed call records in the mobile phone according to 150 missed call records as a group, taking the number of missed call records in the mobile phone as 250 as an example, the contacts in the mobile phone are packed into two missed call record data packets, and two encapsulated missed call record information are obtained by encapsulating the two missed call record data packets, then the mobile phone continuously transmits the two encapsulated missed call record information to the vehicle, and the Bluetooth phone APP in the vehicle calls the Bluetooth framework to receive the two encapsulated missed call record information in sequence, which facilitates subsequent fast display on the Bluetooth phone APP through the way of batch transmission of missed call record information, without waiting for all missed call records to be transmitted to the Bluetooth phone APP before updating and displaying, reducing the user waiting time for updating the missed call records and improving the user experience.

[0057] In a preferred embodiment, the Bluetooth phone APP re-establishes the PBAP connection between the Bluetooth phone APP and the server every time the Bluetooth phone APP synchronizes the contacts and the call records, and issues a command to disconnect the PBAP connection after the download is completed, because if the PBAP connection is always connected, sometimes the synchronization time is long and unresponsive, which is only suitable for short connection.

[0058] In a preferred embodiment, the Bluetooth phone APP no longer judges whether the PBAP is connected when judging the Bluetooth connection state, and the Bluetooth phone APP no longer judges whether the PBAP is connected in other states, avoiding the time consumed by the judgment process and improving the user experience.

[0059] The application can directly synchronize the contact information and the call record information in the server to the Bluetooth phone APP, without extracting through the system database of the vehicle machine, thereby improving the information synchronization efficiency. Meanwhile, after synchronizing the contact information and the call record information each time, the Bluetooth phone APP of the client calls the Bluetooth framework to send a disconnection PBAP connection instruction, so that the server and the Bluetooth phone APP are disconnected from the PBAP connection, and the Bluetooth phone APP will be closed in the synchronization state, thereby avoiding the problem that the Bluetooth phone APP is always in the synchronization state due to the PBAP connection which cannot be disconnected automatically in the prior art, and reducing the negative impact on the user experience.
