[0040] In order to better understand the technical solution of this specification, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] It should be clear that the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0042] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

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

[0044] Reference Figure 1 A flow chart of a Bluetooth phone contact synchronization method provided for an embodiment of the present application, the flow of the method is described as follows: S101: Establish a PBAP connection between the Bluetooth phone APP in the client and the 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 log 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 back the decompressed contact information to the Bluetooth phone APP of the client in sequence, and update and display 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 communicate and connect 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 based on the PBAP connection, direct communication between the mobile phone and the Bluetooth phone APP is realized, and the information synchronization request includes a contact information request, a call record information request, etc.; after that, the mobile phone packs and packages the contacts stored in the mobile phone in turn according to the received contact information request, obtains a number of packaged contact information, and sends the several packaged contact information through the Bluetooth framework ework is transmitted to the Bluetooth phone APP one by one. The Bluetooth phone APP decompresses several packaged contact information and controls the vehicle's Bluetooth phone APP to receive the decompressed contact information and update the displayed contact information in sequence by calling back the second callback interface in the Bluetooth framework; among them, the second callback interface is a callback interface for single contact information transmission, that is, a callback interface for single transmission of one packaged contact information. Through the second callback interface, the contacts in the mobile phone can be transferred to the Bluetooth phone APP in batches, and the contacts can be updated and displayed on the Bluetooth phone APP immediately after the transmission. There is no need to wait until all contacts are synchronized to the Bluetooth phone APP before updating the display, which reduces the time users wait for updating contacts and improves the user experience.

[0046] S104: When the contact information is fully synchronized, receive the multiple encapsulated call record information continuously transmitted by the server in response to the call record information request, and decompress the multiple encapsulated call record information; S105: Call back the decompressed call record information to the Bluetooth phone APP of the client in sequence, and update and display the call record information; at the same time, after the call record information is fully synchronized, the Bluetooth phone APP sends a disconnect PBAP connection instruction to disconnect the Bluetooth phone APP calling the Bluetooth framework to send a disconnect PBAP connection instruction to disconnect the PBAP connection between the Bluetooth phone APP and the server.

[0047] In a preferred embodiment, still taking the client as a vehicle and the server as a mobile phone as an example, when all contacts in the mobile phone are completely synchronized to the Bluetooth phone APP, the mobile phone will package and encapsulate the call records stored in the mobile phone in sequence according to the received call record information request, obtain a number of encapsulated call record information, and transmit the several encapsulated call record information to the Bluetooth phone APP one by one, the Bluetooth phone APP decompresses the several encapsulated contact information and controls the vehicle's Bluetooth phone APP to receive the decompressed encapsulated call record information and update and display the encapsulated call record information in sequence by calling back the third callback interface in the Bluetooth framework; wherein the third callback interface is a callback interface for single call record information transmission, that is, a callback interface for single transmission of one encapsulated call record information, through the third callback interface, the call records in the mobile phone can be transmitted to the Bluetooth phone APP in batches, and updated and displayed on the Bluetooth phone APP immediately after transmission, without waiting until all call records are synchronized to the Bluetooth phone APP before updating the display, reducing the time users wait for call record updates and improving user experience. When all call records in the mobile phone are completely synchronized to the Bluetooth phone APP, the vehicle's Bluetooth phone APP sends a disconnect PBAP connection instruction to disconnect the PBAP connection between the Bluetooth phone APP and the server. The Bluetooth phone APP will turn off the synchronization state, avoiding the problem in the prior art that the Bluetooth phone APP is always in a synchronization state due to the Bluetooth framework's inability to disconnect itself, thereby reducing the negative impact on user experience.

[0048] In a preferred embodiment, the call records include missed call records, received call records, and outgoing call records. After each type of call record is synchronously updated, the third callback interface in the Bluetooth framework needs to be called back to ensure the synchronous update and display of the Bluetooth phone APP.

[0049] Optionally, after sending an information synchronization request to the server based on the PBAP connection, the method further includes: calling back a first callback interface to enable the Bluetooth phone APP to execute synchronization of the contact information; the first interface is a callback interface for starting synchronization of the Bluetooth phone APP in the client.

[0050] In a preferred embodiment, the contact start operation is called back through the callback interface on Contact Callback Start, wherein the contact start operation will force the Bluetooth phone APP to execute the start of contact downloading, which is equivalent to notifying the Bluetooth phone APP of the start of contact downloading, so that the Bluetooth phone APP is in a synchronous ready state, and can quickly receive the decompressed contact information transmitted by the Bluetooth framework, thereby reducing the response time of the Bluetooth phone APP.

[0051] Optionally, the receiving of a number of encapsulated contact information continuously transmitted by the server in response to the contact information request includes: the server determining the number of contacts in the server according to the contact information request; when the number of contacts exceeds a preset contact threshold, the server packages the contacts in the server based on the preset contact threshold, and packages the packaged contacts to obtain a number of encapsulated contact information; the server continuously transmits a number of encapsulated contact information to the client, and the client receives the number of encapsulated contact information in turn.

[0052] In a preferred embodiment, the client is still taken as a vehicle and the server is taken as a mobile phone for explanation. Taking the preset contact threshold of 200 as an example, since the number of contacts stored in the mobile phone may be large, a one-time transmission will cause a large delay and the Bluetooth phone APP will update and display slowly. For this reason, the mobile phone will determine the number of contacts in the mobile phone according to the contact information request; when the number of contacts exceeds 200, the mobile phone will package 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 the five contact data packets are encapsulated to obtain five encapsulated contact information. Then, the mobile phone continuously transmits the five encapsulated contact information to the vehicle, and the Bluetooth phone APP in the vehicle calls the Bluetooth framework to receive the five encapsulated contact information in turn. The contact information is transmitted in batches to facilitate the subsequent quick display on the Bluetooth phone APP, without waiting for all contacts to be transmitted to the Bluetooth phone APP before updating the display, thereby reducing the time users wait to update contacts and improving the user experience.

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

[0054] In a preferred embodiment, since vcard defines a method for organizing personal information and can be used for the transmission and exchange of personal information, the present application uses the vcard data format to encapsulate contacts. vcard uses fields to describe a piece of information about a person, such as the TEL field represents a phone number, and the parameter WORK indicates that the phone number is a work phone number, etc. vcard uses a row-oriented organization format. In addition to multiple rows in the field value, each row represents a complete piece of information. The vcard data format can better reflect the information characteristics of the contact, and can quickly and effectively display the contact information when the Bluetooth phone APP updates the display.

[0055] Optionally, the receiving of a number of encapsulated call record information continuously transmitted by the server in response to the call record information request includes: the server determining 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 packages the call records in the server based on the preset call record threshold, and encapsulates the packaged call records to obtain a number of encapsulated call record information; the server continuously transmits a number of encapsulated call record information to the client, and the client receives the number of encapsulated call record information in turn.

[0056] In a preferred embodiment, the client is still taken as a vehicle and the server is taken as a mobile phone for explanation. For example, the call record is a missed call record and the preset call record threshold is 150. Since the number of missed call records stored in the mobile phone may be large, a one-time transmission will cause a large delay and the Bluetooth phone APP will update and display slowly. For this reason, the mobile phone will determine 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 will package the missed call records in the mobile phone as a group of 150 missed call records. For example, the number of missed call records in the mobile phone is 250. , the contacts in the mobile phone are packaged into 2 missed call record data packets, and the 2 missed call record data packets are encapsulated to obtain 2 encapsulated missed call record information. Then, the mobile phone continuously transmits the 2 encapsulated missed call record information to the vehicle, and the Bluetooth phone APP in the vehicle calls the Bluetooth framework to receive the 2 encapsulated missed call record information in sequence. The missed call record information is transmitted in batches to facilitate subsequent quick display on the Bluetooth phone APP. There is no need to wait for all missed call records to be transmitted to the Bluetooth phone APP before updating the display, which reduces the time users wait for the update of missed call records and improves the user experience.

[0057] In a preferred embodiment, each time the Bluetooth phone APP synchronizes contacts and call records, it will re-establish the PBAP connection between the Bluetooth phone APP and the server. After the download is complete, the Bluetooth phone APP sends an instruction to disconnect the PBAP connection to the PBAP connection between the Bluetooth phone APP and the server. Because if the PBAP connection is always connected, sometimes there will be a long synchronization time without response, it is only suitable for short connections.

[0058] In a preferred embodiment, the Bluetooth phone APP no longer determines whether the PBAP is connected when determining the Bluetooth connection status. The Bluetooth phone APP also no longer determines whether the PBAP is connected in other states, thereby avoiding the time consumed by the determination process and improving the user experience.

[0059] This application can directly synchronize the contact information and call log information in the server to the Bluetooth phone APP without having to extract it from the system database of the vehicle computer, thereby improving the efficiency of information synchronization. At the same time, after each synchronization of contact information and call log information, the client's Bluetooth phone APP calls the Bluetooth framework to send a disconnect PBAP connection instruction, so that the server and the Bluetooth phone APP disconnect the PBAP connection, and the Bluetooth phone APP will turn off the synchronization state, avoiding the problem in the prior art that the Bluetooth phone APP is always in a synchronization state due to the inability to disconnect the PBAP connection by itself, thereby reducing the negative impact on user experience.
