The OTA upgrading method comprises the following steps:

The electronic equipment sends an upgrading request carrying version information to a server, the server determines a corresponding upgrading packet based on the version information carried by the received upgrading request, the upgrading packet is packaged into a plurality of data packets, and the server sends each data packet corresponding to the upgrading packet to the electronic equipment. In the process that the server sends the data packet corresponding to the upgrade packet to the electronic equipment, the electronic equipment sends a corresponding response message or a confirmation message when receiving the first data packet sent by the server, the response message or the confirmation message is used for identifying that the corresponding data packet is received, and the server sends a second data packet to the electronic equipment when receiving the response message sent by the electronic equipment; and the server retransmits the first data packet under the condition that the response message sent by the electronic equipment is not received. And the server sends a corresponding notification message to the electronic equipment under the condition that all data packets corresponding to the upgrade package are sent to the electronic equipment, and the electronic equipment sends a response message corresponding to the notification message to the server when receiving the notification message.

In order to solve the technical problems, an embodiment of the present application provides a data processing method, which determines first information based on a first identifier and a second identifier; and transmitting the first information to the second electronic device through message interaction with the second electronic device. The data processing method may be adapted to different transactions requiring at least two data interactions to complete. Wherein the first identifier characterizes the requested service; a second identifier characterizes the service-related execution action; the first information characterizes data that is required to be sent to the second electronic device to complete the performing action.

The technical scheme of the application is further elaborated below with reference to the drawings in the specification and the specific embodiments.

Fig. 1 shows an interaction diagram of a data processing method according to an embodiment of the present application. Referring to fig. 1, the data processing method in the present embodiment includes:

s101: the first electronic device determines first information based on the first identifier and the second identifier; the first identifier characterizes the requested service; the second identifier characterizes the service-related execution action; the first information characterizes data that is required to be sent to a second electronic device to complete the performing act.

Here, the first identity may correspond to a service instance identity (SIID, service Instance ID), or to an application layer service identity. The service instance is used for realizing a corresponding service, and the application layer service is used for providing the corresponding service, wherein the service comprises at least one of OTA upgrading, security authentication and negotiation secret key.

The second identifier may be an Instance Identifier (IID) for identifying an Instance corresponding to the application layer service, the Instance characterizing an execution action associated with the service corresponding to the first identifier. In practical applications, examples may include at least one of: OTA upgrade instance, security authentication instance, negotiation key instance.

It should be noted that one first identifier corresponds to at least one second identifier. A second, different identifier corresponding to the same first identifier characterizes a different execution action associated with the service corresponding to the first identifier.

When the first electronic device is a device requesting the OTA upgrade service, the first information may include information such as an identifier and a version number of an object to be upgraded; the object to be upgraded includes an application in the first electronic device, firmware in the first electronic device, and the like. Firmware refers to a program written in an 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 provides an upgrade service for the OTA server, the first information comprises a corresponding upgrade package, and the upgrade package is determined based on the identification and the version number of the object to be upgraded.

In the case that the service of the first identifier representation request corresponds to security authentication, the first information includes related data that the first electronic device needs to send to the second electronic device for security authentication.

S102: the first electronic equipment transmits the first information to the second electronic equipment in the process of message interaction with the second electronic equipment.

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. Wherein the message is used for carrying 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 encapsulated into at least two messages, the first electronic device may also send all 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 the messages of each batch is at least two, the first electronic device continuously sends all the messages of 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 at least two messages in the first batch to the second electronic device, and when receiving a confirmation message sent by the second electronic device aiming at the messages in the first batch, at least one message corresponding to the first information is sent to the second electronic device. The confirmation message characterizes at least one message corresponding to the first information received by the second electronic device.

When receiving any message representation sent by the second electronic device and not completely receiving all data corresponding to the first information sent by the first electronic device, the first electronic device determines corresponding packet loss data from the first information based on the identification of the received data represented by the message representation sent by the second electronic device, and resends the determined packet loss data to the second electronic device.

In the scheme provided by the embodiment, the service requested is represented by the first identifier, the execution action related to the service is represented by the second identifier, the first electronic device carries the first information determined based on the first identifier and the second identifier through the interaction message in the process of carrying out message interaction with the second electronic device, and the data processing method can be suitable for different transactions which can be completed after at least two times of data interaction. After sending a message, the first electronic device can send the next message without waiting for a response message corresponding to the message, so that the data interaction efficiency and the data processing efficiency can be improved.

In an embodiment, the message that the first electronic device interacts with the second electronic device is encapsulated according to a set message format; wherein,,

the set message format includes: a first field, a second field, a third field, and a fourth field; the first field is used for writing a first sequence number; the written first serial number is a use serial number and is used for identifying data carried in the corresponding message and tracking whether the message is sent or not; the second field is used for writing a second sequence number; the second serial number is a confirmation serial number and is used for identifying that the electronic equipment has received all valid messages with the serial number smaller than or equal to the second serial number and notifying the opposite party that all messages before the serial number represented by the Ack have been received; the third field is a window field and is used for representing the number of effective messages which can be cached by the electronic equipment and prompting the opposite party, and before any Ack message is not received, the opposite party can send more messages to the my party; the valid message characterizes a message carrying data; the fourth field is used to carry data.

In practical application, the first field corresponds to a Seq, and is used for identifying an effective message, wherein the effective message characterizes a message with data carried in the fourth field; the second field corresponds to Ack and the third field corresponds to window Win. Here, the first sequence number in the first field of the different valid message is consecutive and incremented; the second sequence number written by the second field cannot overwrite the first sequence number in the first field of the non-received valid message. For example, the first electronic device continuously sends 5 pieces of effective information to the second electronic device, the first fields of the 5 pieces of effective information are 1, 2, 3, 4 and 5, respectively, and when the second electronic device receives the effective information with the first sequence number of 4 of the first field and the first sequence number of which is corresponding to 1, 2, 3 and 5, the second electronic device does not receive the effective information with the first sequence number of 4 of the first field, so that when the second electronic device replies to the effective information sent by the first electronic device, the second sequence number written in the second field of the corresponding information is 3, which indicates that the second electronic device has received all the effective information with the first sequence number of less than or equal to 3 sent by the first electronic device.

In practice, the Seq may be incremented from 0 by an increment value of 1, and then incremented to (2 ³² -1) the Seq correspondence of the next valid message is 0. Here, the Seq may be incremented from 1 by an increment value of 1, and from the Seq to 2 ³² When the Seq correspondence of the next valid message is 1.

The second sequence number written in the second field is dynamically updated along with the first sequence number corresponding to the first field in the valid message received by the electronic equipment. Here, when the fourth field in any message received by the electronic device is empty, it characterizes that the message is not a valid message, and the electronic device does not need to answer to the message, i.e. it does not need to send an acknowledgement message for the message identifying that the message has been received. That is, after receiving the message, the electronic device does not separately send an acknowledgement message for identifying that the message has been received without having to send a valid message to the electronic device that sent the message; in the case that a valid message needs to be sent to the electronic device that sent the message, the sequence number of the second field representation in the first valid message sent by the electronic device after receiving the message is the same as the sequence number of the second field representation in the last message sent before receiving the message.

In practical application, the third field characterizes that the number of the effective messages which can be cached by the electronic device is greater than or equal to 2, so that the electronic device sending the effective messages can continuously send at least two effective messages to the electronic device, and the electronic device receiving the effective messages can answer when receiving the at least two effective messages, and does not need to answer for each effective message, thereby improving the message transmission efficiency.

It should be noted that, the number of valid messages that the third field characterizes the electronic device may be determined based on the corresponding buffer space and the maximum number of bits occupied by one valid message. The number of currently cacheable active messages represented by the third field is dynamically updated as the progress of the processing of the active messages. For example, the first electronic device updates the number of valid messages currently cacheable by the first electronic device in real time when the first electronic device finishes processing at least one cached valid message.

In the initialization process, the first electronic device and the second electronic device initialize the following parameters:

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

when the first electronic device initializes the parameters, the LocalSeq corresponds to a first field of the first electronic device, the LocalAck corresponds to a second field of the first electronic device, and the LocalWin corresponds to a third field of the first electronic device; remoteSeq corresponds to a first field of the second electronic device, remoteAck corresponds to a second field of the second electronic device, and RemoteWin corresponds to a third field of the second electronic device. The method comprises the steps that LocalWin characterizes the number of effective messages which can be currently cached by first electronic equipment, and is used for identifying the total message quantity of the effective messages which can be continuously sent to the first electronic equipment by second electronic equipment; remoteWin characterizes the number of valid messages currently cacheable by the second electronic device, identifying the total amount of messages that the first electronic device can continuously send valid messages to the second electronic device. For example, when remotewin=14, the token first electronic device may currently send 14 valid messages continuously to the second electronic device.

When the second electronic device initializes the parameters, the LocalSeq corresponds to a first field of the second electronic device, the LocalAck corresponds to a second field of the second electronic device, and the LocalWin corresponds to a third field of the second electronic device; remoteSeq corresponds to a first field of the first electronic device, remoteAck corresponds to a second field of the first electronic device, and RemoteWin corresponds to a third field of the first electronic device. The LocalWin characterizes the number of the effective messages which can be currently cached by the second electronic equipment and is used for identifying the total message quantity of the effective messages which can be continuously sent to the second electronic equipment by the first electronic equipment; remoteWin characterizes the number of valid messages that the first electronic device can currently cache, and is used to identify the total number of messages that the second electronic device can continuously send valid messages to the first electronic device.

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

In the scheme provided by the embodiment, whether the messages are sent or not is tracked through the use sequence numbers written in the first field, so that the messages can be sent orderly, the confirmation sequence numbers written in the second field are used for notifying the opposite side that all the messages before the sequence numbers represented by the Ack are received, the reliable transmission of the messages can be ensured, the electronic equipment can be ensured to be capable of receiving all the messages finally, the opposite side is prompted through the third field, the opposite side can send more messages to the my side before any Ack message is not received, the electronic equipment does not need to answer every time when receiving one message, and the electronic equipment can continuously send at least two messages, so that the transmission efficiency of the messages can be improved.

In an embodiment, fig. 2 is a schematic diagram illustrating an implementation flow of a first electronic device transmitting first information in the data processing method provided in the embodiment of the present application. As shown in fig. 2, in a process of performing message interaction with a receiving end, the first electronic device transmits the first information to the second electronic device, and the method includes:

s201: generating at least one second message based on the first information; each second message in the at least one second message correspondingly carries 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 data that can be carried by the fourth field of the set message format, the first information is encapsulated into at least two second messages. And the data carried by all the second messages in the at least two second messages form all the data of the first information, and the number of bits occupied by the data carried by the fourth field of each second message is smaller than or equal to the maximum number of bits corresponding to the data carried by the fourth field of the set message format. The second message may be marked as ActionMessage.

Since the fourth fields in the second message all carry data, the second message is a valid message.

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 valid message last sent by the second electronic device and received by the first electronic device. The third field in each second message is used to identify the number of valid messages that the first electronic device is currently buffering in order for the second electronic device to determine the total number of valid messages that can be continuously sent to the first electronic device.

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

Here, the specific implementation process of sending at least one second message to the second electronic device refers to the description related to the transmission of the first information to the second electronic device in S102, which is not described herein in detail.

In the scheme provided by the embodiment, the first information is encapsulated into at least one second message according to the set message format, and when the number of the second messages corresponding to the first information is at least two, because the number of the effective messages which can be buffered initially by the second electronic device is greater than or equal to 2, the first electronic device can continuously send at least two second messages carrying the data of the first information to the second electronic device, that is, after sending one second message, the next second message is not required to be sent after receiving the response message corresponding to the second message, thereby improving the interaction efficiency and the transmission efficiency of the messages. After receiving the effective message sent by the second electronic device, the first electronic device can bear the data of the first information in the message sent by the second electronic device, and can also characterize the sequence number corresponding to the received effective message, so that the data processing efficiency can be improved.

In an embodiment, the sending the at least one second message to the second electronic device includes: and continuously transmitting at least one second message in the at least one second message to the second electronic device based on a third field in the message received by the first electronic device last time.

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

In the scheme provided by the embodiment, since the third field in the last received message of the first electronic device characterizes the number of the valid messages that can be cached currently by the second electronic device, the number of the valid messages that can be cached initially by the second electronic device is greater than or equal to 2, the first electronic device can continuously send at least two pieces of second messages carrying the data of the first information to the second electronic device, and the efficiency of the second messages can be improved.

In an embodiment, in a case that a third field in the last received message of 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 total message amount of the at least one second message, the continuously sending at least one second message of the at least one second message to the second electronic device includes: and continuously transmitting all second messages in the at least one second message to the second electronic equipment.

And when the number of the valid messages which can be cached currently by the second electronic device is larger than or equal to the total number of the at least one second message generated based on the first information, the first electronic device continuously sends all the second messages in the at least one second message to the second electronic device under the condition that the first electronic device determines the number of the valid messages which can be cached currently by the second electronic device based on the third field in the last received message.

In practical application, when the number of the effective messages which can be currently cached by the second electronic device is 14, and the total message amount of the second messages generated based on the first information is 10, the first electronic device continuously sends the 10 second messages to the second electronic device.

It should be noted that, when the number of the messages that the second electronic device can currently buffer is smaller than the total number of the messages of the at least one second message generated based on the first information, the first electronic device continuously sends the first number of the second messages in the at least one second message corresponding to the first information 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 2.

And the second electronic equipment updates the number of the effective messages which can be currently cached by the second electronic equipment under the condition that the second electronic equipment receives at least one second message and the at least one second message is processed.

When the first electronic device receives a third message sent by the second electronic device, the first electronic device determines whether the second electronic device has received all second messages in the first number of second messages based on the second sequence number represented by the second field in the third 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 number of first messages, it is represented whether all the second messages in the first number of second messages have been received by the second electronic device. The first electronic device continuously sends a second number of second messages to the second electronic device based on a third field in the third message characterizing the number of valid messages that the second electronic device is currently caching. The second messages of the second quantity are all second messages which are not sent in the second messages corresponding to the first information.

And 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 number of the first messages, representing that the second electronic equipment receives part of the second messages in the first number of the second messages. The first electronic device characterizes the number of valid messages currently cacheable by the second electronic device based on a third field in the third message, and continuously sends a third number of second messages to the second electronic device based on the second field in the third message. The third number of second messages includes second messages which are not sent in the second messages corresponding to the first information and second messages which are not received by the second electronic equipment in the first number of second messages. The second message which is not received by the second electronic equipment represents the second message of which the first sequence number of the first field is larger than the second sequence number corresponding to the second field in the third message.

In the solution provided in this embodiment, when the third field in the last received message of the first electronic device indicates that the number of the valid messages that can be currently cached by the second electronic device is greater than or equal to the total message amount of the at least one second message, the second electronic device may be indicated to cache all the second messages corresponding to the first information, so that the first electronic device continuously sends all the second messages corresponding to the first information to the second electronic device, and transmission efficiency of the second messages may be improved.

Here, the second electronic device is characterized as not successfully receiving all the second messages sent by the first electronic device, if the third sequence number and the fourth sequence number are different.

The first electronic equipment determines a second message corresponding to a fourth sequence number larger than the third sequence number based on the third sequence number and the fourth sequence number, obtains a second message which is not received by the second electronic equipment, and retransmits the determined second message to the second electronic equipment.

In the case that the first sequence number written in the first field in ActionStart is 1, the second sequence number written in the second field in the ActionMessage is 1. The data (at least one of numbers and letters) written by the third field in the ActionMessage characterizes the number of valid messages that the second electronic device can currently cache.

Here, the fourth field in the ActionMessage may be empty, where the ActionMessage is used as a confirmation message, and is only used to answer to the ActionStart sent by the first electronic device, so as to notify the first electronic device that the first identifier and the second identifier have been received by the second electronic device currently. At this time, the first sequence number written in the first field in the ActionMessage is 0, which indicates that the fourth field in the ActionMessage is empty.

The fourth field in the ActionMessage may also carry part or all of data in second information, where the second information is determined by the second electronic device based on the first identifier and the second identifier, and the second information characterizes data that needs to be sent to the first electronic device to complete the execution action corresponding to the second identifier. At this time, the first sequence number written in the first field in the ActionMessage is 1, which indicates that the fourth field in the ActionMessage carries data.

S404: and under the condition that the first electronic equipment receives the first message sent by the second electronic equipment, the first electronic equipment performs message interaction with the second electronic equipment, and the first information is transmitted to the second electronic equipment.

Here, the first electronic device transmits the first information determined in S402 to the second electronic device, in the case of receiving the first message sent by the second electronic device. The specific implementation process is referred to the related description in the above embodiments, and is not repeated here.

In an actual application, when receiving an ActionMessage sent by a second electronic device based on ActionStart, the first electronic device stores data of a third field in the ActionMessage, so that the data based on the third field in the ActionMessage transmits first information to the second electronic device.

In an actual application, the data corresponding to the first information is carried in a fourth field in at least one ActionMessage.

It should be noted that, after the first electronic device sends the first identifier and the second identifier to the second electronic device, and when the first message sent by the second electronic device is not received within the set duration, the first electronic device characterizes that the second electronic device does not receive the first identifier and the second identifier, where S401 is executed again to resend the first identifier and the second identifier to the second electronic device.

It should be noted that, when the first electronic device performs the execution action related to the service corresponding to the first identifier, an end request may be sent to the second electronic device to release the related resource, where the end request may correspond to the TransactionEndReq.

And when receiving the end request sent by the first electronic device, the second electronic device sends a message for identifying the end of confirmation, for example, genericEndResp, to the first electronic device based on the analysis results of all the received ActionMessage, and marks the execution action corresponding to the second identification as completed. Here, when the analysis result indicates that all ActionMessage analysis is normal, the GenericEndResp characterization is performed normally, and the second electronic device may splice the data carried in the fourth field in all the received ActionMessage based on the sequence numbers of the first field characterizations in all the ActionMessage, so as to obtain the first information; when the analysis result represents any ActionMessage analysis exception, the GenericEndResp represents an execution exception.

When the first electronic device receives the GenericEndResp sent by the second electronic device, the processing result can be reported to the application layer based on the GenericEndResp. Here, when the GenericEndResp characterizes an execution exception, a notification message for identifying a processing failure is reported to the application layer; when the GenericEndResp token performs normally, a notification message for identifying that the process was successful is reported to the application layer. The notification message carries a first identifier and a second identifier.

In the scheme provided by the embodiment, after the first electronic device sends the first identifier and the second identifier to the second electronic device, when receiving the first message sent by the second electronic device and used for representing that the first identifier and the second identifier are received, the first electronic device performs message interaction with the second electronic device, and transmits the first information determined based on the first identifier and the second identifier to the second electronic device, so that the second device can receive the first identifier and the second identifier, and executing actions related to the service requested by the first electronic device are completed based on the first information, so that the first electronic device can acquire the corresponding service.

In an embodiment, the first electronic device corresponds to a service provider, and fig. 5 shows an interaction diagram of a data processing method according to another embodiment of the present application. Referring to fig. 5, the data processing method in the present embodiment includes:

S501: the second electronic device sends the first identifier and the second identifier to the first electronic device.

In practical application, the second electronic device may send a start message to the first electronic device when the second electronic device establishes a communication connection with the first electronic device. For example, actionStart. The startup message comprises a first field, a second field, a third field and a fourth field, wherein the first field seq=1, the second field ack=0, the third field Window is used for identifying the number of the valid messages which can be currently cached by the second electronic device, and the fourth field carries a first identifier and a second identifier.

S502: and the first electronic equipment receives the first identifier and the second identifier sent by the second electronic equipment.

S503: and under the condition that the first identifier and the second identifier are confirmed to be valid, the first electronic device performs message interaction with the second electronic device, and transmits the first information to the second electronic device.

And under the condition that the first electronic equipment receives the first identifier and the second identifier sent by the second electronic equipment, the first electronic equipment checks the first identifier and the second identifier sent by the second electronic equipment based on the set first identifier and the set second identifier to obtain a check result. When the first electronic equipment searches the first identifier which is the same as or matched with the first identifier sent by the second electronic equipment from the set first identifier, the first identifier sent by the second electronic equipment is characterized to be valid; and when the first electronic equipment searches the first identifier which is different from or not matched with the first identifier sent by the second electronic equipment from the set first identifier, the first identifier sent by the second electronic equipment is invalid. When the first electronic equipment searches the second identifier which is the same as or matched with the second identifier sent by the second electronic equipment from the set second identifier, the second identifier sent by the second electronic equipment is characterized to be valid; and when the first electronic equipment searches the second identifier which is different from or not matched with the second identifier sent by the second electronic equipment from the set second identifier, the second identifier sent by the second electronic equipment is invalid.

And under the condition that the verification result indicates that the first identifier and the second identifier sent by the second electronic equipment are both effective, transmitting the first information to the second electronic equipment through message interaction with the second electronic equipment. The first electronic device may determine, based on a third field in the startup message sent by the second electronic device, a number of valid messages that the second electronic device may currently cache, so as to transmit the first information to the second electronic device based on the number of valid messages that the second electronic device may currently cache. The detailed implementation is referred to the related description of the above embodiments, and is not repeated here.

And ending the data processing flow when the verification result indicates that any one of the first identifier and the second identifier sent by the second electronic equipment is invalid.

In the scheme provided by the embodiment, the first electronic device determines the first information based on the first identifier and the second identifier under the condition that the received first identifier and the received second identifier are valid, so that the first information is transmitted to the second electronic device in the process of data interaction with the second electronic device, and the data processing flow is ended under the condition that the received first identifier or the received second identifier is invalid, so that the first information returned to the second electronic device is data corresponding to the service requested by the first electronic device, the correctness of the data is ensured, and the corresponding service is provided for the first electronic device.

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

s601: the terminal sends the first identifier and the second identifier to the server. The first identifier characterizes the requested service; the second identification characterizes the service-related execution action.

The first identifier may correspond to an OTA service instance identifier, and the first identifier characterizes that the requested service corresponds to an OTA upgrade service. The second identification characterizes an OTA service related execution action, e.g., OTA upgrade.

In practical application, the terminal sends ActionStart to the server. The first field seq=1 in the ActionStart, the second field ack=0 in the ActionStart, the third field window=16 in the ActionStart, which is used for identifying the number of the valid messages that the terminal can currently cache, and the fourth field in the ActionStart carries the first identifier and the second identifier.

S602: the server sends a first message to the terminal under the condition that the first identifier and the second identifier are confirmed to be valid; the first message characterizes the receipt of the first and second identifications by the server.

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 characterizes the number of valid messages that the server can currently buffer, 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 characterizes data that is required to be sent to the server to complete the performing action.

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

Note that S601 and S603 may be executed simultaneously.

S604: and under the condition that the terminal receives the first message sent by the server, carrying out message interaction with the server, and transmitting the first message to the server.

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

In practical application, because the total number of bits occupied by the identifier and version number of the object to be upgraded is smaller, the first information may 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 characterizes data required to be sent to the terminal for completing the execution action.

Here, the second information includes a corresponding upgrade package.

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

Here, since the number of bits occupied by the upgrade package is large, the server generates at least two actionmessages based on the second information, and the data carried by the fourth field in all actionmessages in the at least two actionmessages forms all data of the second information.

And when the total message amount of the at least two actionmessages is smaller than or equal to the number of the valid messages which can be cached currently and are characterized by the third field in the ActionStart, continuously sending all the actionmessages in the at least two actionmessages to the terminal. For example, when the third field in ActionStart corresponds to 16, if the total message amount of the 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.

And when the total quantity of the at least two ActionMessage messages is larger than the quantity of the current cacheable effective messages of the terminal represented by the third field in the ActionStart, continuously sending the first quantity of ActionMessage in the at least two ActionMessage to the terminal. The first number is less than or equal to the number of active messages that the terminal is currently buffering.

S607: and the terminal sends a third message to the server under the condition of receiving at least part of data of the second information.

And the terminal sends a third message to the server under the condition of receiving the ActionMessage corresponding to the second information sent by the server. The sequence number written in the second field in the third message represents that the terminal has received all actionmessages of which the sequence numbers represented by the first field in the actionmessages sent by the server are smaller than or equal to the sequence numbers 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, it may determine whether the sequence numbers of the first field representation of the received actionmessages are continuous or not based on the sequence numbers of the first field representation of each of the at least two actionmessages received by the server, and when the sequence numbers of the first field representation of the received actionmessages are discontinuous, send a third message to the server. The terminal may also send a third message to the server when the determined result indicates that the sequence number of the first field of the ActionMessage is continuous and the maximum sequence number of the first field of the ActionMessage is equal to the number of the valid messages that the terminal can currently cache.

For example, the sequence numbers of the first field characterizations 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, the sequence number of the first field representation of the ActionMessage received by the terminal corresponds to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, the second field ack=10 in the third message sent by the terminal, and the sequence number of the first field representation of the ActionMessage received by the terminal is 1 to 10.

When the number of the valid messages which are represented by the fourth field in the third message and can be cached currently by the terminal is 10, because the sequence number represented by the second field in the third message is 10, and the sequence number represented by the first field in the ActionMessage which is transmitted by the server last time is 14, the two sequence numbers are different, so that the server continuously transmits the ActionMessage of 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 also an unsent ActionMessage corresponding to the second information, and the number of valid messages that can be currently cached by the terminal may be represented by the fourth field in the third message, and the ActionMessage with seq=11, 12, 13, 14 and at least one unsent ActionMessage corresponding to the second information may be continuously sent to the terminal.

Here, when the fourth field in the third message is empty, the sequence number of the first field representation of the third message is the same as the sequence number of the first field representation in the last valid message (e.g., 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, the token terminal has received all the messages for carrying the data of the upgrade package, and at this time, the server does not need to respond to the third message, that is, the server does not need to separately send a message for identifying that the third message has been received to the third message.

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

The terminal sends an end request message, e.g., transactionEndReq, to the server in case of receiving all ActionMessage for carrying data of the upgrade package. The sequence number of the first field representation in the end request message is the same as the sequence number of the first field representation in the last valid message sent by the terminal to the server. The sequence number of the second field representation in the end message is the same as the sequence number of the first field representation in the ActionMessage of the data for carrying the second information, which is sent by the server last time.

S609: and the server sends a confirmation ending message to the terminal under the condition of receiving the ending request message.

And the server sends a confirmation ending message to the server under the condition that the ending request message sent by the terminal is received and the received third message sent by the terminal represents that the terminal has received all the messages used for bearing the data of the upgrade package, and marks the execution action represented by the second identifier as completed.

S610: and the terminal reports the corresponding execution result to the application layer under the condition of receiving the confirmation ending message.

Here, when all actionmessages corresponding to the second information have been received, the terminal analyzes all actionmessages corresponding to the second information, and obtains an analysis result. The analysis result comprises a sequence number of the first field representation corresponding to each ActionMessage and data carried by a corresponding fourth field. When the terminal can successfully analyze the data carried by all the ActionMessage, reporting a message for identifying normal execution to an application layer; and the terminal sorts the data carried by the corresponding fourth field based on the sequence number of the first field corresponding to each ActionMessage in the analysis result to obtain sorted data, and reports the sorted data to the application layer. The sorted data form corresponding second information (i.e. upgrade package) for the OTA upgrade service corresponding to the first identifier to upgrade the corresponding application program or firmware by using the upgrade package.

When any ActionMessage corresponding to the second information is analyzed by the terminal to make errors, OTA upgrading is ended, a processing result for identifying upgrading failure is reported to the application layer, and the data processing flow is ended.

In the scheme provided by the embodiment, the server can continuously send at least two ActionMessage to the terminal, and the terminal does not need to respond to each ActionMessage, so that the transmission efficiency of the OTA upgrade package can be improved, and the OTA upgrade speed is improved.
