The technical solutions of the present application will be further elaborated below with reference to the accompanying drawings and specific embodiments of the description.

FIG. 1 shows an interaction diagram of a data processing method provided by an embodiment of the present application. 1, the data processing method in this embodiment includes:

S101: The first electronic device determines first information based on the first identifier and the second identifier; the first identifier represents a requested service; the second identifier represents an execution action related to the service; the first information represents Data sent to the second electronic device required to complete the execution action.

Here, the first identifier may correspond to a service instance identifier (SIID, Service Instance ID), or correspond to an application layer service identifier. The service instance is used to implement the corresponding service, and the application layer service is used to provide the corresponding service, and the service includes at least one of OTA upgrade, security authentication, and negotiated secret key.

The second identifier may be an instance identifier (IID, Instance ID), which is used to identify an instance corresponding to the application layer service, and the instance represents an execution action related to the service corresponding to the first identifier. In practical applications, the instances may include at least one of the following: an OTA upgrade instance, a security authentication instance, and a negotiated key instance.

It should be noted that one first identifier corresponds to at least one second identifier. Different second identifiers corresponding to the same first identifier represent different execution actions related to the service corresponding to the first identifier.

In the case where the service requested by the first identifier represents an OTA upgrade, when the first electronic device is a device requesting an OTA upgrade service, the first information may include information such as the identifier and version number of the object to be upgraded; the object to be upgraded includes An application program in the first electronic device, firmware in the first electronic device, and the like. Firmware refers to the program written in Erasable Programmable Read-Only Memory (EPROM, Erasable Programmable ROM) or Electrically Erasable Programmable Read-Only Memory (EEPROM, Electrically Erasable Programmable Read-only Memory) of an electronic device. When the first electronic device is a server that provides an upgrade service for OTA, the first information includes a corresponding upgrade package, and the upgrade package is determined based on the identifier and version number of the object to be upgraded.

In the case that the service corresponding to the request of the first identification representation is security authentication, the first information includes relevant data that the first electronic device needs to send to the second electronic device to perform security authentication.

S102: The first electronic device transmits the first information to the second electronic device during the message interaction process with the second electronic device.

Here, the first electronic device may encapsulate the first information into at least one message, and transmit the at least one message to the second electronic device. The message is used to carry part or all of the data in the first information. The first electronic device may continuously send all messages corresponding to the first information to the second electronic device.

When the first information is packaged into at least two messages, the first electronic device may also send all the messages in the at least two messages to the second electronic device in batches. The number of messages per batch is at least one. When the number of messages in each batch is at least two, the first electronic device continuously sends all the messages in each batch to the second electronic device. When all the messages included in the first information are sent in at least two batches, the first electronic device continuously sends all the messages in the at least two messages in the first batch to the second electronic device, and after receiving the second electronic device When the electronic device sends a confirmation message for the first batch of messages, it sends at least one message corresponding to the first information to the second electronic device. The confirmation message represents that the second electronic device has received at least one message corresponding to the first information.

It should be noted that, in the process that the first electronic device interacts with the second electronic device and transmits the first information to the second electronic device, the first electronic device receives any message sent by the second electronic device. When not completely receiving all the data corresponding to the first information sent by the first electronic device, determine the corresponding packet loss data from the first information based on the identifier of the received data represented by the message sent by the second electronic device , and re-send the determined packet loss data to the second electronic device.

In the solution provided by this embodiment, the requested service is represented by the first identifier, and the execution action related to the service is represented by the second identifier. The first information determined by the first identifier and the second identifier, and the data processing method can be applied to different transactions that can be completed by at least two data interactions. After sending a message, the first electronic device can send the next message without waiting for a response message corresponding to the message, which can improve data interaction efficiency and data processing efficiency.

The set message format includes: a first field, a second field, a third field and a fourth field; the first field is used to write a first sequence number; the written first sequence number is a use sequence number, used for Identifies the data carried in the corresponding message, which is used to track whether the message has been delivered; the second field is used to write the second sequence number; the second sequence number is the confirmation sequence number, which is used to identify that the electronic device has received the sequence number less than or equal to All valid messages of the second serial number are used to notify the other party that all messages before the serial number represented by Ack have been received; the third field is a window field, used to represent the number of valid messages that can be cached by the electronic device, used to prompt The other party, before receiving any Ack message, how many messages the other party can send to us; the valid message represents a message carrying data; the fourth field is used to carry data.

In practical applications, the first field corresponds to Seq, which is used to identify a valid message, and the valid message represents a message carrying data in the fourth field; the second field corresponds to Ack, and the third field corresponds to the window Win. Here, the first sequence numbers in the first fields of different valid messages are consecutive and increasing; the second sequence numbers written in the second fields cannot cover the first sequence numbers in the first fields of the valid messages that are not received. For example, the first electronic device continuously sends 5 pieces of valid information to the second electronic device, and the first fields of the 5 pieces of valid information are 1, 2, 3, 4, and 5 respectively. When the first sequence number of the first field of the sent valid message corresponds to 1, 2, 3, and 5, since the second electronic device has not received the valid message with the first sequence number of the first field being 4, the second electronic device does not receive the valid message whose first sequence number is 4. When the electronic device responds to a valid message sent by the first electronic device, the second sequence number written in the second field of the corresponding message is 3, indicating that the second electronic device has received the first sequence number sent by the first electronic device. All valid messages less than or equal to 3.

In practical applications, Seq can be incremented from 0 according to the increment value of 1. When Seq increments to (2 ³² -1), the Seq of the next valid message corresponds to 0. Here, Seq can be incremented from 1 according to the increment value of 1. When Seq is incremented to 2 ³² , the Seq of the next valid message corresponds to 1.

The second sequence number written in the second field is dynamically updated with the first sequence number corresponding to the first field in the valid message received by the electronic device. Here, when the fourth field in any message received by the electronic device is empty, it indicates that the message is not a valid message, and the electronic device does not need to respond to the message, that is, it does not need to send a message for identifying the received message. A confirmation message to this message. That is to say, after the electronic device receives the message, without the need to send a valid message to the electronic device that sent the message, the electronic device no longer sends a separate confirmation message for identifying that the message has been received; When a valid message needs to be sent to the electronic device that sent the message, the sequence number represented by the second field in the first valid message sent by the electronic device after receiving the message, and the last valid message sent before the message is received The sequence numbers represented by the second field in the message are the same.

In practical applications, the third field indicates that the number of valid messages that can be cached by the electronic device is greater than or equal to 2, so that the electronic device sending valid messages can continuously send at least two valid messages to the electronic device, and the electronic device receiving valid messages It is possible to reply when at least two valid messages are received, and it is not necessary to reply for each valid message, which can improve the efficiency of message transmission.

It should be noted that the third field indicates that the number of valid messages that can be cached by the electronic device may be determined based on the corresponding cache space and the maximum number of bits occupied by a valid message. The number of currently cacheable valid messages represented by the third field is dynamically updated along with the processing progress of valid messages. For example, when the first electronic device has processed at least one cached valid message, the first electronic device updates the number of valid messages currently cached by the first electronic device in real time.

During the initialization process of the first electronic device and the second electronic device, the following parameters are initialized:

LocalSeq, LocalAck, LocalWin; RemoteSeq, RemoteAck, RemoteWin.

When the first electronic device initializes the above parameters, LocalSeq corresponds to the first field of the first electronic device, LocalAck corresponds to the second field of the first electronic device, LocalWin corresponds to the third field of the first electronic device; RemoteSeq corresponds to The first field of the second electronic device, RemoteAck corresponds to the second field of the second electronic device, and RemoteWin corresponds to the third field of the second electronic device. Wherein, LocalWin represents the number of valid messages currently cacheable by the first electronic device, and is used to identify the total number of valid messages that the second electronic device can continuously send to the first electronic device; RemoteWin represents the current cacheable messages of the second electronic device The number of valid messages is used to identify the total number of valid messages that the first electronic device can continuously send to the second electronic device. For example, when RemoteWin=14, it means that the first electronic device can currently continuously send 14 valid messages to the second electronic device.

When the second electronic device initializes the above parameters, LocalSeq corresponds to the first field of the second electronic device, LocalAck corresponds to the second field of the second electronic device, LocalWin corresponds to the third field of the second electronic device; RemoteSeq corresponds to the second field of the second electronic device; The first field of the first electronic device, RemoteAck corresponds to the second field of the first electronic device, and RemoteWin corresponds to the third field of the first electronic device. Wherein, LocalWin represents the number of valid messages currently cacheable by the second electronic device, and is used to identify the total number of valid messages that the first electronic device can continuously send to the second electronic device; RemoteWin represents the current cacheable messages of the first electronic device The number of valid messages is used to identify the total number of valid messages that the second electronic device can continuously send to the first electronic device.

It should be noted that, in the initialization process, the third field indicates that the number of valid messages that can be cached by the electronic device is greater than or equal to 2.

In the solution provided by this embodiment, whether the message has been delivered is tracked through the usage sequence number written in the first field, so that the orderly delivery of the message can be ensured, and the confirmation sequence number written in the second field is used to notify the other party that the message represented by Ack has been delivered. All messages before the serial number have been received, which can ensure the reliable transmission of the message, and can ensure that the electronic device can finally receive all the messages. The third field is used to prompt the other party. Before receiving any Ack message, the other party can send us a message. No matter how many messages are sent, the electronic device does not need to respond every time a message is received, and the electronic device can continuously send at least two messages, thereby improving the transmission efficiency of messages.

In an embodiment, FIG. 2 shows a schematic flowchart of the implementation of the first electronic device transmitting the first information in the data processing method provided by the embodiment of the present application. As shown in FIG. 2 , in the process of message interaction with the receiving end, the first electronic device transmits the first information to the second electronic device, including:

S201: Generate at least one second message based on the first information; each second message in the at least one second message corresponds to carrying all or part of the data in the first information.

The first electronic device encapsulates the first information into at least one second message according to the set message format. Here, when the number of bits occupied by the first information is greater than the maximum number of bits corresponding to the data that can be carried in the fourth field of the set message format, the first information is encapsulated into at least two second messages. The data carried by all the second messages in the at least two second messages constitute all the data of the first message, and the number of bits occupied by the data carried in the fourth field of each second message is less than or equal to the number of bits occupied by the set message format. The maximum number of bits corresponding to the data that the four fields can carry. The second message may be marked as ActionMessage.

Since the fourth fields in the second message all carry data, the second messages are all valid messages.

The second sequence number written in the second field in each second message is determined based on the sequence number represented by the first field in the last valid message sent by the second electronic device received by the first electronic device. The third field in each second message is used to identify the number of valid messages currently cacheable by the first electronic device, so that the second electronic device can determine the total number of valid messages that can be continuously sent to the first electronic device.

S202: Send the at least one second message to the second electronic device.

Here, for the specific implementation process of sending at least one second message to the second electronic device, please refer to the relevant description of transmitting the first information to the second electronic device in S102, which is not repeated here.

In the solution provided in this embodiment, the first information is encapsulated into at least one second message according to the set message format. When there are at least two second messages corresponding to the first information, since the second electronic device can initially cache The number of valid messages is greater than or equal to 2, therefore, the first electronic device can continuously send at least two second messages carrying data of the first information to the second electronic device, that is, after sending one second message , it is not necessary to send the next second message after receiving the response message corresponding to the second message, thereby improving the interaction efficiency and the message transmission efficiency. After receiving the valid message sent by the second electronic device, the first electronic device can carry the data of the first information in the message sent to the second electronic device, and can also represent the sequence number corresponding to the received valid message, which can improve data processing. effectiveness.

In one embodiment, the sending the at least one second message to the second electronic device includes: based on a third field in a message last received by the first electronic device, sending the at least one second message to the second electronic device. At least one of the second messages is continuously sent to the second electronic device.

Here, the first electronic device determines the number of valid messages currently cacheable by the second electronic device based on the third field in the last received message, and based on the number of valid messages currently cached by the second electronic device, at least At least one second message in the one second message is continuously sent to the second electronic device, so that all the second messages corresponding to the first information are transmitted to the second electronic device.

In the solution provided in this embodiment, since the third field in the message last received by the first electronic device represents the number of valid messages currently cacheable by the second electronic device, the number of valid messages that can be cached initially by the second electronic device is When the number is greater than or equal to 2, the first electronic device can continuously send at least two second messages carrying data of the first information to the second electronic device, which can improve the efficiency of the second messages.

In one embodiment, the third field in the message last received by the first electronic device indicates that the number of valid messages currently cacheable by the second electronic device is greater than or equal to the number of the at least one second message. In the case of the total number of messages, the continuously sending at least one second message in the at least one second message to the second electronic device includes: sending all the second messages in the at least one second message continuously to the second electronic device.

Here, if the first electronic device determines the number of valid messages currently cacheable by the second electronic device based on the third field in the last received message, when the number of valid messages currently cached by the second electronic device is When the total amount of the at least one second message generated based on the first information is greater than or equal to the total amount of messages, all the second messages in the at least one second message are continuously sent to the second electronic device.

In practical applications, when the number of valid messages currently cacheable by the second electronic device is 14, and the total number of second messages generated based on the first information is 10, the first electronic device stores the 10 second messages as second messages. The message is continuously sent to the second electronic device.

It should be noted that, when the number of messages currently cacheable by the second electronic device is less than the total number of messages of at least one second message generated based on the first information, the first electronic device stores the at least one second message corresponding to the first information. The first number of second messages in are continuously sent to the second electronic device. The first number is less than or equal to the number of messages currently cacheable by the second electronic device. The first number may be greater than or equal to two.

When the second electronic device receives at least one second message and has processed the at least one second message, the second electronic device updates the number of valid messages currently cacheable by the second electronic device.

When the first electronic device receives the third message sent by the second electronic device, the first electronic device determines whether the second electronic device has received the first number of messages based on the second sequence number represented by the second field in the third message. All of the second messages in the second message. The third message is used to identify that the second electronic device has received at least one second message sent by the first electronic device.

Here, when the second sequence number represented by the second field in the third message is equal to the first sequence number with the largest value corresponding to the first field in the first message of the first quantity, it means that the second electronic device has received the first quantity All second messages in the second message. The first electronic device continuously sends the second number of second messages to the second electronic device based on the third field in the third message representing the number of valid messages currently cacheable by the second electronic device. The second number of second messages are all unsent second messages in the second messages corresponding to the first information.

When the second sequence number represented by the second field in the third message is smaller than the first sequence number with the largest value corresponding to the first field of the first message of the first quantity, it means that the second electronic device has received the second message of the first quantity Part of the second message in . Based on the third field in the third message, the first electronic device represents the number of valid messages currently cacheable by the second electronic device, and based on the second field in the third message, continuously forwards the third number of second messages to the second electronic device. Electronic device sent. The third number of second messages includes unsent second messages among the second messages corresponding to the first information and second messages that are not received by the second electronic device among the first number of second messages. The second message that is not received by the second electronic device represents a second message in which the first sequence number of the first field is greater than the second sequence number corresponding to the second field in the third message.

In the solution provided by this embodiment, the third field in the message last received by the first electronic device indicates that the number of valid messages currently cacheable by the second electronic device is greater than or equal to the at least one second message In the case of the total number of messages, it means that the second electronic device can cache all the second messages corresponding to the first information. Therefore, the first electronic device continuously sends all the second messages corresponding to the first information to the second electronic device. The transmission efficiency of the second message is improved.

When the first electronic device receives the first identification and the second identification sent by the second electronic device, based on the set first identification and the set second identification, the first identification and the second identification sent by the second electronic device The second identification is verified to obtain a verification result. Here, when the first electronic device finds from the set first identification that it is the same as or matches with the first identification sent by the second electronic device, it indicates that the first identification sent by the second electronic device is valid; When the set first identifier is found to be different from or does not match the first identifier sent by the second electronic device, it indicates that the first identifier sent by the second electronic device is invalid. When the first electronic device finds the same or matches with the second identification sent by the second electronic device from the set second identification, it indicates that the second identification sent by the second electronic device is valid; When it is found that it is different from or does not match the second identifier sent by the second electronic device, it indicates that the second identifier sent by the second electronic device is invalid.

When the verification result indicates that the first identification and the second identification sent by the second electronic device are both valid, the first information is transmitted to the second electronic device by performing message interaction with the second electronic device. Wherein, the first electronic device can determine the number of valid messages currently cacheable by the second electronic device based on the third field in the startup message sent by the second electronic device, so as to be based on the number of valid messages currently cacheable by the second electronic device , and transmit the first information to the second electronic device. For a specific implementation manner, please refer to the relevant descriptions of the foregoing embodiments, which will not be repeated here.

In the case that the verification result indicates that any one of the first identifier and the second identifier sent by the second electronic device is invalid, the data processing flow ends.

In the solution provided in this embodiment, the first electronic device determines the first information based on the first identifier and the second identifier only when it confirms that the received first identifier and the second identifier are valid. In the process of data exchange between the two electronic devices, the first information is transmitted to the second electronic device, and when the received first identification or the second identification is invalid, the data processing flow is ended, thereby ensuring that the second electronic device is sent to the second electronic device.

As an application embodiment of the present application, FIG. 6 shows an interaction diagram of a data processing method provided by the application embodiment of the present application. As shown in Figure 6, in the application scenario of OTA upgrade of the terminal, the data processing method includes:

S601: The terminal sends the first identifier and the second identifier to the server. The first identifier represents a requested service; the second identifier represents an execution action related to the service.

The first identifier may correspond to an OTA service instance identifier, and the first identifier represents that the requested service corresponds to an OTA upgrade service. The second identifier represents an execution action related to the OTA service, for example, an OTA upgrade.

In practical applications, the terminal sends ActionStart to the server. The first field Seq=1 in ActionStart, the second field Ack=0 in ActionStart, and the third field Window=16 in ActionStart are used to identify the number of valid messages that the terminal can currently cache. Bearing the first identification and the second identification.

S602: The server sends a first message to the terminal under the condition of confirming that both the first identifier and the second identifier are valid; the first message indicates that the server has received the first identifier and the second identifier logo.

The first field of the first message Seq=0, the second field of the first message Ack=1, the third field of the first message represents the number of valid messages currently cacheable by the server, and the fourth field of the first message is empty.

S603: The terminal determines first information based on the first identifier and the second identifier; the first information represents data that needs to be sent to the server to complete the execution action.

Here, the first information may include information such as the identifier and version number of the object to be upgraded; the object to be upgraded includes the application program in the terminal, the firmware in the terminal, and the like.

It should be noted that S601 and S603 may be executed simultaneously.

S604: In the case of receiving the first message sent by the server, the terminal performs message interaction with the server, and transmits the first information to the server.

The terminal encapsulates the first information into at least one ActionMessage; the data carried by all ActionMessages in the at least one ActionMessage constitutes all data of the first information. The fourth field in ActionMessage is used to carry the data of the first information.

In practical applications, since the total number of bits occupied by the identifier and version number of the object to be upgraded is small, the first information can be encapsulated into an ActionMessage.

S605: The server determines second information based on the first identifier, the second identifier, and the first information; the second information represents data that needs to be sent to the terminal to complete the execution action.

Here, the second information includes the corresponding upgrade package.

S606: The server performs message interaction with the terminal, and transmits the second information to the terminal.

Here, since the upgrade package occupies a large number of bits, the server generates at least two ActionMessages based on the second information, and the data carried in the fourth field in all ActionMessages in the at least two ActionMessages constitute all data of the second information.

When the total amount of the at least two ActionMessages is less than or equal to the number of valid messages currently cacheable by the terminal represented by the third field in the ActionStart, all ActionMessages in the at least two ActionMessages are continuously sent to the terminal. For example, when the third field in ActionStart corresponds to 16, if the total amount of messages in at least two ActionMessages is less than or equal to 16, all ActionMessages in the at least two ActionMessages are continuously sent to the terminal.

When the total amount of messages of the at least two ActionMessages is greater than the number of valid messages currently cacheable by the terminal represented by the third field in the ActionStart, the first number of ActionMessages in the at least two ActionMessages are continuously sent to the terminal. The first number is less than or equal to the number of valid messages currently buffered by the terminal.

S607: The terminal sends a third message to the server when at least part of the data of the second information is received.

In the case of receiving the ActionMessage corresponding to the second information sent by the server, the terminal sends a third message to the server. The sequence number written in the second field in the third message indicates that the terminal has received all ActionMessages whose sequence number represented by the first field in the ActionMessage sent by the server is less than or equal to the sequence number represented by the second field in the third message.

It should be noted that, when the terminal receives at least two ActionMessages corresponding to the second information sent by the server, the terminal may determine whether to receive the sequence number represented by the first field of each ActionMessage in the at least two ActionMessages sent by the server. Whether the sequence numbers represented by the first field of the ActionMessage are continuous, and when the determination result indicates that the sequence numbers represented by the first field of the ActionMessage received are discontinuous, a third message is sent to the server. The terminal may also send the third message to the server when the determination result indicates that the sequence numbers represented by the first field of the ActionMessage are consecutive, and the maximum sequence number represented by the first field of the ActionMessage is equal to the number of valid messages that the terminal can currently cache.

For example, the sequence numbers represented by the first field of at least two ActionMessages sent by the server correspond to: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and the terminal receives The sequence number represented by the first field of the ActionMessage corresponds to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, and the second field Ack=10 in the third message sent by the terminal, Indicates that the terminal has received ActionMessages with serial numbers 1 to 10 represented by the first field.

When the fourth field in the third message indicates that the number of valid messages that the terminal can currently cache is 10, since the sequence number represented by the second field in the third message is 10, the first field in the ActionMessage sent by the server for the last time is 10. The sequence number represented by the field is 14, and the two sequence numbers are different. Therefore, the server continuously sends ActionMessages with Seq=11, 12, 13, and 14 to the terminal based on the sequence number represented by the second field in the third message. Here, after the server sends 14 ActionMessages in S607, there is still an unsent ActionMessage corresponding to the second message. Based on the fourth field in the third message, the number of valid messages that can be cached by the terminal can be represented, and Seq=11 , ActionMessages of 12, 13, 14, and at least one unsent ActionMessage corresponding to the second message are continuously sent to the terminal.

Here, when the fourth field in the third message is empty, the sequence number represented by the first field of the third message is the same as the sequence number represented by the first field in the last valid message (eg, ActionStart) sent by the terminal to the server. When the fourth field in the third message is empty, and the sequence number represented by the second field in the third message is the same as the maximum sequence number corresponding to the first field in the ActionMessage generated based on the second information, it indicates that the terminal has received the For all messages carrying the data of the upgrade package, at this time, the server does not need to respond to the third message, that is, the server does not need to send a separate message for the third message to identify that the third message has been received.

S608: The terminal sends an end request message to the server.

The terminal sends an end request message, for example, TransactionEndReq, to the server in the case of receiving all the ActionMessages used to carry the data of the upgrade package. The sequence number represented by the first field in the end request message is the same as the sequence number represented by the first field in the last valid message sent by the terminal to the server. The sequence number represented by the second field in the end message is the same as the sequence number represented by the first field in the ActionMessage for carrying the data of the second information sent by the server last time.

S609: In the case of receiving the end request message, the server sends a confirmation end message to the terminal.

When the server receives the end request message sent by the terminal, and the received third message sent by the terminal indicates that the terminal has received all the messages used to carry the data of the upgrade package, the server sends a confirmation end message to the server, and sends the second message to the server. The execution action of the identity token is marked as completed.

S610: In the case of receiving the confirmation end message, the terminal reports the corresponding execution result to the application layer.

Here, when the terminal has received all the ActionMessages corresponding to the second information, the terminal parses all the ActionMessages corresponding to the second information to obtain the analysis results. The parsing result includes the sequence number represented by the first field corresponding to each ActionMessage and the data carried by the corresponding fourth field. When the terminal can successfully parse out the data carried by all ActionMessages, it reports a message to the application layer to identify the normal execution; based on the sequence number of the first field corresponding to each ActionMessage in the parsing result, the terminal parses the data carried by the corresponding fourth field Perform sorting to obtain sorted data, and report the sorted data to the application layer. The sorted data forms corresponding second information (ie, an upgrade package), which is used for the OTA upgrade service corresponding to the first identifier to use the upgrade package to perform OTA upgrade on the corresponding application or firmware.

When an error occurs in the terminal parsing any ActionMessage corresponding to the second information, the OTA upgrade is terminated, the processing result used to identify the upgrade failure is reported to the application layer, and the data processing flow is ended.

In the solution provided by this embodiment, the server can continuously send at least two ActionMessages to the terminal, and the terminal does not need to respond to each ActionMessage, thereby improving the transmission efficiency of the OTA upgrade package and the speed of the OTA upgrade.
