Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to a communication data transmission method, device, electronic equipment and storage medium. Background Art

[0002] In-vehicle systems (such as in-vehicle navigation or entertainment systems) usually synchronize address books and call records with mobile terminals (such as smartphones) through the Bluetooth PBAP (Phone Book Access Profile) protocol. The PBAP protocol is built on OBEX (Object Exchange Protocol) and transmits address books and call records in the vCard data format.

[0003] However, the PBAP protocol does not allow the car computer to save the contacts and call records of the paired mobile phone, so all contacts and call records need to be synchronized every time Bluetooth is disconnected and reconnected.

[0004] In addition, the contact and call log data transmitted by the PBAP protocol adopts the vCard format. vCard is a plain text-based electronic business card format. Although it has good scalability and compatibility, its uncompressed nature results in a huge amount of data and low transmission efficiency when transmitting a large number of contacts.

[0005] For example, in actual applications, a user's address book may contain thousands of contacts, and it may take a long time to transmit uncompressed vCard data. For example, it may take 10-20 seconds to transmit 1,000 contacts (excluding avatars and other additional data, which is 120Kbytes), which will cause a long waiting time for users and affect the user experience. As a result, car owners must wait 10-20 seconds before they can make a call through the car computer after getting in the car. Summary of the invention

[0048] The embodiments of the present invention provide a communication data transmission method, device, electronic device and storage medium, which are used to solve the technical problems of low transmission efficiency, long transmission time and high bandwidth occupancy of existing address books and call records.

[0049] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1 , Figure 1 A flow chart of the steps of a communication data transmission method provided by an embodiment of the present invention.

[0051] A communication data transmission method provided by the present invention is applied to a mobile terminal, wherein the mobile terminal communicates with a vehicle-mounted system. The method may specifically include the following steps:

[0052] Step 101, obtaining communication data; the communication data includes address book and call records;

[0053] In the embodiment of the present invention, the mobile terminal may be a portable device such as a mobile phone or a tablet.

[0054] In the embodiment of the present invention, the communication data may be stored in the vCard data format and transmitted via the PBAP (PhoneBook Access Profile) protocol, including but not limited to the address book and call records.

[0055] vCard is a plain text-based electronic business card format.

[0056] PBAP is an upper layer protocol based on OBEX, which can synchronize information such as address books and call logs on mobile phones and other devices with phonebook functions.

[0057] Step 102, compressing the address book and call records to obtain compressed data;

[0058] In order to reduce the transmission volume of the address book and call records, after obtaining the address book and call records in vCard format, the present invention can compress them to obtain compressed data.

[0059] In one example, a compression algorithm such as ZIP, LZMA, etc. may be used to compress the address book and call logs, and the original vCard data may be compressed into smaller binary data, usually about 5% of the original size.

[0060] For example, 1000 contacts have 120KBbytes of data, which can be compressed to about 6KBbytes.

[0061] Step 103, encapsulate the compressed data to obtain an encapsulated contact file;

[0062] In order to enable the compressed data to be transmitted through the PBAP protocol, the compressed data may be encapsulated into a packaged contact file in the vCard format.

[0063] Step 104, when receiving a communication data acquisition request from the vehicle terminal, the encapsulated contact file is sent to the vehicle system; the vehicle system is used to decompress the encapsulated contact file to obtain the address book and call records.

[0064] PCE (Phone Book Access Client Equipment), such as a vehicle-mounted system, can send a communication data acquisition request to a mobile terminal to request the address book and call logs. After receiving the communication data acquisition request, the mobile terminal returns the encapsulated contact file to the PCE. Since the PBAP protocol supports the transmission of vCard format, and vCard supports embedding binary data such as photos, this operation complies with the protocol standard and does not require modification of the PBAP protocol.

[0065] After receiving the encapsulated contact file, the PCE can decompress the address book and call records from it, thereby realizing fast transmission of the address book and call records.

[0066] The present invention obtains communication data; the communication data includes a contact list and call records; compresses the contact list and call records to obtain compressed data; encapsulates the compressed data to obtain an encapsulated contact file; when a communication data acquisition request is received from a vehicle-mounted terminal, the encapsulated contact file is sent to the vehicle-mounted system; the vehicle-mounted system is used to decompress the encapsulated contact file to obtain the contact list and call records. This improves data transmission efficiency, reduces transmission time, and reduces Bluetooth bandwidth occupancy.

[0067] See also Figure 2 , Figure 2 A flow chart of a communication data transmission method provided by another embodiment of the present invention. Specifically, the following steps may be included:

[0068] Step 201, obtaining communication data; the communication data includes address book and call records;

[0069] Step 202, using BASE64 encoding to compress the address book and call records into binary data in a preset format to obtain compressed data;

[0070] In the embodiment of the present invention, in order to reduce the transmission volume of the address book and call records, after obtaining the address book and call records in the vCard format, the present invention can compress them to obtain compressed data.

[0071] In one example, a compression algorithm such as ZIP, LZMA, etc. may be used to compress the address book and call logs, and the original vCard data may be compressed into smaller binary data, usually about 5% of the original size.

[0072] For example, 1000 contacts have 120Kbytes of data, which can be compressed to about 6Kbytes.

[0073] Step 203, creating a special contact file;

[0074] Step 204, marking the target name in the first target field of the special contact file;

[0075] Step 205, adding the compressed data to the second target field of the special contact file to obtain a packaged contact file;

[0076] In an embodiment of the present invention, a special contact file may be created to encapsulate the compressed data. The format of the special contact file may be a vCard format, as follows:

[0077] BEGIN:VCARD

[0078] VERSION:3.0

[0079] FN:Compressed Data

[0080] N:Compressed;Data;;;

[0081] PHOTO;ENCODING=b;TYPE=ZIP:<BASE64 encoding of compressed binary data>

[0082] END:VCARD

[0083] in:

[0084] FN and N fields (first target field): Identified as a special contact (target name) with the name "CompressedData".

[0085] PHOTO field (second target field): uses the feature of vCard that supports binary data to embed the compressed address book and call log data. The data is encoded in BASE64 and the TYPE is specified as a compressed format (such as ZIP).

[0086] Step 206: When receiving a communication data acquisition request from the vehicle-mounted terminal, the packaged contact file is sent to the vehicle-mounted system; the vehicle-mounted system is used to decompress the packaged contact file to obtain the address book and call records.

[0087] In the embodiment of the present invention, the compressed data is binary, so it is converted into ASCII code using BASE64 encoding, and the size increases by about 35%. For 1,000 contacts, the size of the final packaged contact file data is about 8.1Kbyte, which is 6.7% of the size before compression. Therefore, the amount of data transmitted from the mobile terminal to the vehicle-mounted system is greatly reduced, and the data transmission speed is improved.

[0088] After the vehicle system receives the packaged contact file, it can obtain the address book and call records. The specific steps are as follows:

[0089] S11, identifying the target name in the encapsulated contact file;

[0090] S12, extracting data of a target field from the encapsulated contact file according to the target name;

[0091] S13, decoding the data to obtain compressed data;

[0092] S14, decoding the compressed data to obtain the address book and call records.

[0093] In a specific implementation, a special contact with a target name of "Compressed Data" in the encapsulated contact file can be identified, and then the data in the PHOTO field can be extracted, and the BASE64-encoded binary data can be decoded to obtain the compressed data. The compressed data is then decompressed to restore the original vCard data of the address book and call records. The PCE parses the decompressed vCard data to obtain the contact and call record information. Finally, the contact and call record are presented to the user or stored in a local database.

[0094] The present invention obtains communication data; the communication data includes a contact list and call records; compresses the contact list and call records to obtain compressed data; encapsulates the compressed data to obtain an encapsulated contact file; when a communication data acquisition request is received from a vehicle-mounted terminal, the encapsulated contact file is sent to the vehicle-mounted system; the vehicle-mounted system is used to decompress the encapsulated contact file to obtain the contact list and call records. This improves data transmission efficiency, reduces transmission time, and reduces Bluetooth bandwidth occupancy.
