[0026] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] In order to solve the above technical problems, the present application provides a data transmission method. The data transmission method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, Figure 1 : is a flow chart of a data transmission method provided by an embodiment of the present application. The embodiment of the present application provides a data transmission method, which is applied to a first electronic device. The method may include:

[0030] S101, obtaining a communication link quality between a first electronic device and a second electronic device;

[0031] In this embodiment, the first electronic device may be a device with independent communication capabilities, such as a mobile phone with a SIM card, which stores contact data and has a communication sharing function. The second electronic device does not have independent communication capabilities and needs to rely on the communication sharing function of the first electronic device to realize communication functions such as phone calls or text messages, such as a Pad.

[0032] In the process of the second electronic device relying on the first electronic device for communication sharing, the first electronic device needs to transfer the contact data stored therein to the second electronic device. In addition, before the data transmission, the first electronic device will detect the quality of the communication link between the first electronic device and the second electronic device. The quality of the communication link may include signal strength, bandwidth and stability. Based on the detected quality of the communication link, it can be evaluated whether the current network is suitable for efficient transmission.

[0033] S102, determining a transmission channel and a transmission capacity according to the communication link quality;

[0034] In this embodiment, after the first electronic device detects the quality of the communication link, it can dynamically select a transmission channel for the contact data according to the quality of the communication link. Different transmission channels correspond to different single transmission capacities, which can ensure transmission efficiency and reliability.

[0035] For example, parameters such as signal strength, transmission delay, and packet loss rate between different transmission channels can be detected, and the communication link quality of each transmission channel can be determined based on the above parameters, where the transmission channel can include a P2P (Peer-to-Peer) channel and a Bluetooth channel. If the communication link quality of the P2P channel is good, a high-bandwidth P2P channel can be selected, and the corresponding transmission capacity can be set to 800KB. If the communication link quality of the P2P channel is poor, and the communication link quality of the Bluetooth channel is good, it can be switched to the Bluetooth channel, and the corresponding transmission capacity is set to 50KB.

[0036] S103: Encapsulate the contact data to be transmitted according to the transmission capacity to obtain a data set.

[0037] In the embodiment of the present application, after the transmission channel and the transmission capacity are determined, the contact data in the first electronic device can be dynamically packaged into one or more data sets according to the selected transmission capacity. During the packaging process, each contact data can be added to the data set in turn until the capacity of the data set just reaches the transmission capacity.

[0038] Specifically, in some embodiments, encapsulating the contact data to be transmitted according to the transmission capacity to obtain a data set includes:

[0039] Get the initialized byte array;

[0040] Encapsulating the contact data into the byte array one by one according to the arrangement order of the contact data;

[0041] Until the amount of data accumulated in the byte array reaches the transmission capacity, stop encapsulating the contact data into the byte array to obtain the data set.

[0042] In this embodiment, during the encapsulation process of the contact data, the system may first initialize an empty byte array as a storage container, and then convert each piece of contact data into a byte stream according to the arrangement order of the contact data in the first electronic device, and write them into the byte array one by one.

[0043] At the same time, after each contact data is written into the byte array, the system will dynamically calculate the amount of data accumulated in the current byte array. If the total amount of data in the byte array does not exceed the transmission capacity after adding new contact data, the encapsulation will continue; once the transmission capacity is reached, the encapsulation will stop and the byte array will be sent as a complete data set.

[0044] In this embodiment, the size of each data set can be controlled by dynamically encapsulating each data set one by one, ensuring that the data set can adapt to the capacity requirements of different transmission channels, thereby achieving fast and stable data transmission.

[0045] In some embodiments, before encapsulating the contact data into the byte array one by one according to the arrangement order of the contact data, the method further includes:

[0046] Obtaining version information, sending time and data type of the byte array;

[0047] Generate a metadata header according to the version information, the sending time and the data type;

[0048] Add the metadata header to the byte array.

[0049] In this embodiment, after obtaining the initialized byte array, before encapsulating the contact data into the byte array one by one, the system can first obtain the basic description information of the entire byte array, including version information, sending time, and data type. A metadata header is generated based on this information as the descriptive part of the collection. Among them, the version information is used to identify the format or protocol version of the data collection, the sending time is the estimated sending time of the data collection, and the data type is used to characterize the type of contact data.

[0050] After the metadata header is generated, it will be written to the head of the byte array first to ensure that it is the starting content of the data set and provide guidance for the receiving end to parse the data set. After the metadata header is added, the system will encapsulate the contact data one by one according to the order in which the contact data is arranged.

[0051] In this way, the format of the data collection can be ensured to be standardized, and it is also convenient for the receiving end to efficiently parse and process the specific content in the collection.

[0052] In some embodiments, encapsulating the contact data into the byte array one by one includes:

[0053] For any piece of contact data, obtain the contact identifier and contact information corresponding to the contact data;

[0054] Determine the data length of the contact information;

[0055] The contact identifier, the data length and the contact information are converted into byte streams in sequence and written into the byte array in order to complete the encapsulation of the contact data.

[0056] In this embodiment, during the packaging process of the contact data, for each piece of contact data, the corresponding contact identifier (contact_id) can be determined based on the arrangement order of the contact data, and the contact information of the contact can be extracted. The contact information may include the name, phone number, and email address of the contact.

[0057] After extracting the contact information of the contact, the size of the contact information in the byte stream can be calculated based on the extracted contact information to obtain the data length (data_length). Then, the contact identifier, data length and contact information are converted into byte streams in sequence, and the byte streams are written into the byte array in sequence to ensure that the contact data of the same contact can be compactly arranged in the byte array to complete the encapsulation of the contact data.

[0058] This encapsulation method can significantly improve data transmission efficiency by converting the contact ID, data length and contact information into a compact byte stream and writing it into a byte array in sequence. At the same time, it ensures that the data format is clear, making it easier for the receiving end to quickly parse and accurately process each contact data.

[0059] S104: Send the data set to the second electronic device through the transmission channel.

[0060] In the present application, after the data set is packaged, the first electronic device can send the data set to the second electronic device through the currently selected transmission channel. In addition, during the transmission process, if the network conditions change, the system can dynamically switch the transmission channel based on the real-time communication link quality and continue to send the unfinished data to ensure that the data transmission is not interrupted.

[0061] In the embodiment of the present application, the quality of the communication link between electronic devices can be obtained; and the transmission channel and transmission capacity can be determined based on the quality of the communication link; then data can be encapsulated according to the selected transmission capacity, and the encapsulated data can be transmitted through the selected transmission channel. In this way, the transmission channel can be selected according to the quality of the communication link to ensure that the transmission process uses a better network channel. At the same time, the transmission capacity is determined based on the quality of the communication link, and the maximum carrying capacity of the transmission channel is fully utilized, thereby increasing the speed of data transmission.

[0062] In some embodiments, after sending the data set to the second electronic device through the transmission channel, the method further includes:

[0063] After the network between the first electronic device and the second electronic device is disconnected and reconnected, obtaining a resume transmission instruction sent by the second electronic device;

[0064] Parsing the resume instruction to obtain a first import time and a first contact identifier, wherein the first contact identifier is a contact identifier of the first contact data, the first import time is an import time of the first contact data, and the first contact data is the last successfully imported contact data before the network is interrupted;

[0065] Starting from the contact data next to the first contact data, the contact data continues to be sent to the second electronic device.

[0066] In this embodiment, when the network between the first electronic device and the second electronic device is interrupted and reconnected, the first electronic device receives a resume instruction from the second electronic device, which is used to instruct to continue transmitting contact data to the second electronic device, and the resume instruction includes relevant information of the contact data successfully imported last time.

[0067] Specifically, the first electronic device parses the retransmission instruction, determines the contact information of the last contact data successfully imported before the network interruption, that is, the first import time and the first contact identifier, and based on the first import time and the first contact identifier, the first electronic device can determine the last first contact data successfully imported before the network interruption. It can also determine the next contact data of the first contact data, and then start packaging from the next contact data of the first contact data, and continue to transmit the unfinished contact data to the second electronic device.

[0068] In this way, the untransmitted data can be accurately located and the transmission can be continued from the interruption point, avoiding repeated transmission of completed data, which greatly improves the transmission efficiency.

[0069] In addition, an embodiment of the present application provides another data transmission method, which is applied to a second electronic device and may include:

[0070] receiving a data set sent by the first electronic device, wherein a transmission capacity of the data set is determined based on a quality of a communication link between the first electronic device and the second electronic device;

[0071] Parsing the data set to obtain contact data;

[0072] The contact data are imported into the second electronic device in batches, wherein the contact data in one data set belong to the same batch.

[0073] In this embodiment, the second electronic device is the receiving end of the contact data. The second electronic device receives a data set sent from the first electronic device. The transmission capacity of the data set is dynamically adjusted according to the quality of the communication link between the two devices. Specifically, when the quality of the communication link is better, the transmission capacity is larger and the transmission efficiency is higher.

[0074] After receiving the data set, the received data set is parsed step by step to extract the contact data in the set, and the parsed contact data is imported into the second electronic device in batches, wherein all the contact data in a data set are regarded as the same batch.

[0075] The above-mentioned method of importing contact data in batches simplifies the import process, improves the efficiency of data import, and ensures the integrity of the data.

[0076] In some embodiments, parsing the data set to obtain contact data includes:

[0077] Obtaining a metadata header of the data set;

[0078] Parsing the metadata header to obtain version information, sending time and data type of the data set;

[0079] Determine a target parsing method according to the version information, the sending time and the data type;

[0080] The data set is parsed according to the target parsing method to obtain the contact data in the data set.

[0081] In this embodiment, since the metadata header is located at the beginning of the data set and is used to describe the overall information of the set, after the metadata header, multiple contact data are arranged in sequence. Then, after the second electronic device receives the data set, it can extract the metadata header from the head of the data set, and then parse the metadata header to obtain the version information, sending time and data type of the data set.

[0082] And according to the parsed version information and data type, a suitable target parsing method can be selected to correctly parse the contact data in the data set. Finally, the contact data can be extracted one by one from the data set according to the determined target parsing method.

[0083] In the above method, the parsing method of the contact data can be dynamically adjusted by parsing the result of the metadata header to dynamically adapt to different versions of the data set format, thereby ensuring the compatibility and accuracy of the parsing.

[0084] In some embodiments, parsing the data set according to the target parsing method to obtain the contact data in the data set includes:

[0085] Obtaining any contact identifier in the data set;

[0086] Obtaining the data length from the length flag corresponding to the contact identifier;

[0087] Extracting contact information corresponding to the data length from the data set;

[0088] The contact information is parsed to obtain contact data corresponding to the contact identifier.

[0089] In this embodiment, when parsing any contact data by target parsing, the unique contact identifier (contact_id) of the contact data can be first extracted, and the contact identifier is used to mark the ownership of the contact data. After obtaining the contact identifier, the length flag (data_length) corresponding to the contact data can be found according to the contact identifier. The flag stores the data length of the contact information of the contact, and the data boundary of the contact data can be determined by the data length.

[0090] Subsequently, the data length obtained from the length flag can be used to extract the byte stream after the length flag in the data set according to the data length, and the extracted byte stream can be parsed and converted into readable contact information corresponding to the contact identifier, which may include information such as the contact's name and phone number.

[0091] In this way, by obtaining the contact ID and data length, the contact information of each contact data can be accurately located and extracted, avoiding data confusion during the parsing process and improving the efficiency of data import.

[0092] In some embodiments, after parsing the data set to obtain the contact data, the method further includes:

[0093] Obtaining a first contact identifier of a first contact data in the first batch of contact data, wherein the first contact data is the last contact data in the first batch, and the first batch is any batch of contact data;

[0094] generating an import progress prompt according to the first contact identifier;

[0095] importing the first batch of contact data into the second electronic device;

[0096] During the import process of the first batch of contact data, the import progress prompt is displayed.

[0097] In this embodiment, since the contact data is imported in batches, taking the first batch of contact data as an example, after the first batch of contact data is parsed, the first contact identifier of the last contact data in the first batch of contact data is determined, and the first contact identifier is used to mark the overall import progress of the first batch.

[0098] Then, the percentage of the import progress can be calculated based on the position of the first batch of contact data in all contact data, and an import progress prompt can be generated according to the first contact identifier and the percentage. Then, during the import of the first batch of contact data, the import progress prompt is dynamically displayed so that the user can check the import status of the data at any time.

[0099] For example Figure 2 As shown, the first electronic device is a mobile phone, and the second electronic device is a tablet computer. During the import process, the tablet computer may display an import progress prompt 201, which may be a text message "Importing XXX from mobile phone, 50%".

[0100] This method can generate and display an import progress prompt to prompt the user of the current import status in an intuitive form.

[0101] In some embodiments, after importing the first batch of contact data into the second electronic device, the method further includes:

[0102] In the event that import of contact data in the first batch fails, all contact data in the first batch are re-imported.

[0103] In this embodiment, since the contact data is imported in batches, that is, multiple contact data in the same batch are packaged for import processing. Then, if any contact data fails to be imported during the import of the first batch of contact data, the system will retry to import all contact data in the batch instead of only importing the failed contact data. Compared with importing contact data one by one, batch import reduces the frequency of calling the storage system, greatly reducing system overhead and network communication costs.

[0104] In the above solution, by re-importing the entire batch of data, the error handling logic is simplified and the complexity of item-by-item verification and re-transmission is avoided.

[0105] In some embodiments, after importing the contact data into the second electronic device in batches, the method further includes:

[0106] If there is no failure in importing the contact data in the first batch, obtaining the first contact identifier and the import time of the first contact data;

[0107] Generate import information according to the first contact identifier and the import time;

[0108] The imported information is stored.

[0109] In this embodiment, when all the contact data of the first batch are successfully imported, the system will record the first contact ID of the last contact data in the batch and the import time when the import is completed. Then, import information can be generated based on the first contact ID and the import time, and stored for subsequent data transmission status tracking and breakpoint resumption.

[0110] Then, by recording the import information, the system can accurately locate the data that has been successfully imported, avoiding repeated operations in subsequent transmissions, thereby improving efficiency. In addition, this method provides a basis for breakpoint resumption, ensuring that progress can be quickly resumed after a transmission interruption, reducing resource waste and improving data integrity.

[0111] In some embodiments, after storing the import information, the method further includes:

[0112] After the network between the first electronic device and the second electronic device is disconnected and reconnected, generating and displaying a first control;

[0113] In case of receiving a first input to the first control, in response to the first input, obtaining the most recently generated import information, wherein the first input is used to instruct to continue transmitting the unfinished contact data from the location where the network was last interrupted;

[0114] Generate a resume instruction according to the first contact identifier and the first import time in the import information;

[0115] The resume transmission instruction is sent to the first electronic device, so that the first electronic device continues to send contact data starting from the next contact data of the first contact data corresponding to the first contact identifier and the first import time.

[0116] In this embodiment, when the contact data is not completely transmitted and the network between the first electronic device and the second electronic device is disconnected, the transmission of the contact data is correspondingly interrupted. Then, after the network is reconnected, the system can generate and display a first control on the second electronic device. The first control is used to prompt the user to choose to continue transmitting the unfinished data from the interrupted position.

[0117] like Figure 3 As shown, the first electronic device is a mobile phone, and the second electronic device is a tablet computer. When the contact data is not transmitted, and the network between the first electronic device and the second electronic device is disconnected and reconnected, a text message "The last time the contacts were imported from the mobile phone, an interruption occurred. M contacts were detected and can be imported. Do you want to continue importing?" is displayed on the second electronic device, and a first control 301 "Agree button" and a second control 302 "Reject button" are displayed. If the user makes a first input to the first control, it means that the user agrees to continue to transmit the unfinished data from the interrupted position. If the user makes an input to the second control, it means that the user does not want to continue to transmit the data temporarily.

[0118] When the user performs the first input on the first control, it means that the user wants to continue transferring the unfinished data from the interrupted position. Then, when the user performs the first input on the first control, the system can obtain the most recently generated import information, which includes the first contact identifier and the first import time of the last successful import. This information records the specific location of the last batch of contact data that was transferred.

[0119] Then, a resume instruction can be generated according to the first contact identifier and the first import time, and the resume instruction is used to instruct to resume the transmission from the next contact data of the first contact data that was successfully imported last. Subsequently, the second electronic device sends the resume instruction to the first electronic device, and the first electronic device repackages the unfinished contact data from the interruption position and continues to send it, completing the breakpoint resume.

[0120] In this way, since the import progress is recorded in the import information, after the network is interrupted and reconnected, a resume instruction can be generated according to the recorded import information, thereby achieving accurate breakpoint resume, avoiding repeated data transmission, and improving data transmission efficiency.
