The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

For ease of understanding, a networking architecture implementing the document upgrading method set forth in the present application will be described first.

As shown in fig. 1, the networking architecture includes an upgrade management server 110, a gateway device 120, a gateway device 130, and terminal devices 140 to 160.

As an example, in the networking architecture illustrated in fig. 1, the upgrade management server 110 is communicatively connected to the gateway device 120 and the gateway device 130 based on ethernet. The gateway device 120 and the gateway device 130 are communicatively coupled based on ethernet or radio frequency technology. The gateway device 120 and the terminal devices 140 to 160 are communicatively connected based on radio frequency technology.

It should be noted that, in fig. 1, only two gateway devices are taken as an example, in practical application, the networking architecture may include multiple gateway devices, and the number of gateway devices that the upgrade management server 110 may be connected to is not limited in this application.

Accordingly, in fig. 1, only one gateway device is connected to 3 terminal devices as an example, and in practical application, the number of connectable terminal devices may be set according to the bearing capacity of the gateway device, which is not limited in this application. Meanwhile, the terminal device in fig. 1 only takes the smart lock as an example, and in practical application, the terminal device may also be other devices, for example, a smart television, a smart phone, etc., which is not limited in this application.

Based on the networking architecture illustrated in FIG. 1, upgrade management server 110 may initiate an installed batch upgrade tool (not shown in FIG. 1) based on user operations. After the batch upgrade tool is started, all online gateway devices under the whole networking framework are scanned, and the scanned gateway devices are provided for users.

The user may select at least one gateway device from all gateway devices provided by the upgrade management server 110 as a gateway device involved in the current file upgrade process. As one example, the batch upgrade tool may present the spatial location of the gateway device, e.g., 3 1 units, to the user when providing the scanned gateway device to the user. Through the processing, the user can intuitively select the gateway equipment involved in the current file upgrading process.

Thereafter, the upgrade management server 110 may further provide the user with an upgrade file batch selection interface illustrated in fig. 2, so that the user may select an upgrade file involved in the current upgrade process from upgrade files included in the interface.

Finally, after detecting that the upgrade button in the interface is triggered, the upgrade management server 110 may issue an upgrade task to the gateway device involved in the current file upgrade process. After receiving the upgrade task, the gateway device can execute the file upgrade method provided by the application to control the connected terminal device to upgrade the file.

The file upgrading method provided by the application is described in detail below from the gateway device side and the terminal device side respectively:

first, a method for upgrading a file proposed in the present application is described from a gateway device side:

referring to fig. 3, a flowchart of an embodiment of a method for upgrading a file according to an exemplary embodiment of the present application is provided, and in one example, the method may be applied to a gateway device, such as the

gateway device

120 or 130 illustrated in fig. 1.

As shown in fig. 3, the method comprises the following steps:

step 301: after receiving the upgrade task, the gateway device negotiates with other gateway devices a second channel that is available and is currently in an idle state.

In the application, the upgrade management server 110 may issue an upgrade task to the gateway device connected thereto, and after receiving the upgrade task, the gateway device may control the terminal device connected thereto to perform file upgrade.

In this embodiment of the present application, taking a gateway device as an example, after receiving an upgrade task, the gateway device may first negotiate a channel (hereinafter referred to as a second channel) with other gateway devices, where the second channel meets the following conditions: available and currently in an idle state.

Since the second channel is available and currently in an idle state, different gateway devices correspond to different second channels. As to how the gateway device negotiates the second channel with other gateway devices, the following is shown by way of example, and is not repeated here.

Step 302: the gateway equipment controls all terminal equipment connected with the gateway equipment to switch the working channel from the current first channel to the second channel, and switches the working rate from the current first rate to the second rate.

In this embodiment of the present application, after step 301 is performed and a second channel is negotiated with another gateway device, the gateway device may control all terminal devices connected to the gateway device to switch a working channel from a current channel (hereinafter referred to as a first channel) to the second channel, and switch a working rate from a current rate (hereinafter referred to as a first rate) to a rate corresponding to the second channel (hereinafter referred to as a second rate).

By doing so, it is possible to realize that the gateway apparatus communicates with the terminal apparatus to which it is connected based on the second channel. As to how the gateway device controls all terminal devices connected to the gateway device to switch the working channel from the current first channel to the second channel and switch the working rate from the current first rate to the second rate, it is shown by way of example hereinafter and will not be described in detail herein.

Step 303: the gateway equipment determines target terminal equipment to be subjected to file upgrading from all terminal equipment connected with the gateway equipment, and sends an upgrading instruction to the target terminal equipment under a second channel so that the target terminal equipment receiving the upgrading instruction can execute file upgrading according to the upgrading instruction.

In an application, since not all terminal devices connected to the gateway device are currently in a upgradeable state, for example, in a case where the terminal device fails or the terminal device has been upgraded before, the terminal device is in a non-upgradeable state.

Based on this, in step 303, the gateway device may determine a terminal device to be subjected to file upgrade (hereinafter referred to as a target terminal device) from all the connected terminal devices, and then send an upgrade instruction to the target terminal device under the second channel, so that the target terminal device that receives the upgrade instruction performs file upgrade according to the upgrade instruction.

As to how the gateway device determines the target terminal device to perform the file upgrade from all the connected terminal devices, and how the gateway device sends the upgrade instruction to the target terminal device under the second channel, it is described in the following by different embodiments, and the description is omitted herein.

Thus, the description of the flow shown in fig. 3 is completed.

According to the embodiment, after receiving the upgrade task, the gateway device negotiates with other gateway devices a second channel which is available and is currently in an idle state, controls all the gateway devices connected with the gateway device to switch the working channel from a current first channel to the second channel, switches the working rate from the current first rate to the second rate, determines the target terminal device to be subjected to file upgrade from all the terminal devices connected with the gateway device, and sends an upgrade instruction to the target terminal device under the second channel, so that the target terminal device receiving the upgrade instruction executes file upgrade according to the upgrade instruction, batch upgrade of the terminal devices can be realized, and because the second channel which is available and is currently in an idle state is negotiated with other gateway devices in advance, different gateway devices can be correspondingly different second channels, further, the different gateway devices can control the terminal devices connected with the gateway devices respectively to execute file upgrade through the different second channels, and therefore the phenomenon of signal interference can be effectively avoided.

How the gateway device negotiates the above-mentioned second channel with other gateway devices is described below by means of the embodiment shown in fig. 4.

Referring to fig. 4, a process for implementing step 301 according to an exemplary embodiment of the present application includes the following steps:

step 401: the gateway device selects one of the candidate channels as a target channel.

In the embodiment of the present application, the candidate channel is other channels than the first channel that is currently operating.

As one example, the gateway device may randomly select one channel among the candidate channels as the target channel.

As an example, the gateway apparatus may select a channel that has not been selected before as the target channel in the order of the set candidate channels, starting from the candidate channel that is ranked first.

It should be noted that the foregoing is merely an exemplary description of selecting, by the gateway device, one channel from the candidate channels as the target channel, and in practical application, the gateway device may also select, by other means, one channel from the candidate channels as the target channel, which is not limited in this application.

Step 402: the gateway device sends a broadcast message under the target channel, wherein the broadcast message carries the identification of the target channel so as to instruct other gateway devices to judge whether the current working channel is the target channel.

As an example, the gateway device may send a broadcast message on the target channel selected in step 401, and the other gateway devices may receive the broadcast message on the target channel.

As an example, the broadcast message may carry an identification of the target channel. After receiving the broadcast message, the other gateway device can determine whether the current working channel is the target channel according to the identification of the target channel.

Step 403: receiving a judgment result sent by other gateway equipment, and executing step 404 if the judgment result indicates that the current working channel of the other gateway equipment is not a target channel; otherwise, go back to step 401.

Step 404: the target channel is determined to be the second channel.

The following collectively describes steps 403 and 404:

in the application, after judging whether the current working channel is the target channel according to the identification of the target channel, other gateway devices can send the judging result to the gateway device. As one example, the other gateway device may send the determination result under the target channel, so that the present gateway device may receive the determination result under the target channel.

If the judging result indicates that the current working channel of the other gateway equipment is not the target channel, the gateway equipment can consider that the target channel is in an idle state currently, and the gateway equipment sends a broadcast message under the target channel and receives the judging result under the target channel, so that the target channel is available. It can be seen that the target channel selected in step 401 satisfies the above condition: available and currently in an idle state, so that in step 404 the target channel may be determined to be the second channel.

Otherwise, if the judging result indicates that the current working channel of the other gateway device is the target channel, it may be determined that the target channel selected in step 401 does not meet the above condition, and at this time, the gateway device may return to execute step 401 to implement negotiation with the other gateway device to obtain a second channel.

Thus, the description of the flow shown in fig. 4 is completed.

Through the flow shown in fig. 4, it is finally realized that the gateway device negotiates a second channel with other gateway devices, and because the second channel is available and is currently in an idle state, different gateway devices correspond to different second channels, and further, different gateway devices control respective connected terminal devices to perform file upgrading through different second channels, so that the phenomenon of signal interference can be effectively avoided.

The following describes how the gateway device controls the gateway device and all terminal devices connected to the gateway device to switch the working channel from the current first channel to the second channel and switch the working rate from the current first rate to the second rate by means of the embodiment shown in fig. 5.

Referring to fig. 5, a process for implementing step 302 according to an exemplary embodiment of the present application includes the following steps:

Step 501: and the gateway equipment sends a frequency hopping command to all terminal equipment connected with the gateway equipment under a first channel.

In this embodiment of the present application, the gateway device may send, to all connected terminal devices on the first channel that is currently operating, a frequency hopping command that carries at least the channel identifier (hereinafter referred to as the second channel identifier) and the second rate of the second channel negotiated in step 301.

After receiving the frequency hopping command, the terminal device can reinitialize the built-in radio frequency small plate so as to switch the working channel from the current first channel to the second channel and switch the working rate from the current first rate to the second rate.

Step 502: the gateway device switches the working channel from the current first channel to the second channel and switches the working rate from the current first rate to the second rate.

Thus, the description of the flow shown in fig. 5 is completed.

Through the flow shown in fig. 5, it is finally realized that the gateway device controls all the gateway devices and all the terminal devices connected with the gateway device to switch the working channel from the current first channel to the second channel, and switches the working rate from the current first rate to the second rate, so as to prepare for the subsequent gateway device to control the terminal device to execute file upgrading through the second channel.

In addition, on the basis of the flow shown in fig. 5, after the above step 501 is performed, the flow shown in fig. 6 may also be performed:

referring to fig. 6, a implementation flow after step 501 provided in an exemplary embodiment of the present application includes the following steps:

step 601: the gateway equipment detects whether a frequency hopping response returned by the terminal equipment is received in a first set time after a frequency hopping command is sent to the terminal equipment aiming at each connected terminal equipment.

Step 602: if not, when the frequency hopping command sending times are smaller than the preset value, the gateway equipment sends the frequency hopping command to the terminal equipment again under the first channel, the frequency hopping command carries a second channel identifier and a second rate, so that the terminal equipment receiving the frequency hopping command switches the working channel from the first channel to the second channel corresponding to the second channel identifier, and switches the working rate from the current first rate to the second rate.

The following collectively describes steps 601 and 602:

as an example, after receiving the frequency hopping command and successfully switching the working channel from the current first channel to the second channel according to the frequency hopping command and switching the working rate from the current first rate to the second rate, the terminal device may return a frequency hopping response to the gateway device under the first channel or the second channel.

The gateway device may then detect whether a frequency hopping response returned by the terminal device has been received within a first set time, e.g. 3 seconds. If no frequency hopping response is received, the gateway device may continue to compare the frequency hopping command transmission number with a preset value, for example, 3 times. When the frequency hopping command sending times are smaller than the preset value, the gateway device can send the same frequency hopping command to the terminal device again under the first channel, so that the terminal device receiving the frequency hopping command switches the working channel from the first channel to a second channel corresponding to the second channel identifier, and switches the working rate from the current first rate to the second rate.

Thus, the description of the flow shown in fig. 6 is completed.

By the flow shown in fig. 6, when the frequency hopping response returned by the terminal device is not received, the frequency hopping command is repeatedly sent to the terminal device for a plurality of times, so that the success rate of switching the working channel from the current first channel to the second channel and switching the working rate from the current first rate to the second rate by the terminal device can be improved.

In addition, as an example, after receiving the frequency hopping response returned by the terminal device within the first set time, the gateway device may send the frequency hopping command to the terminal device again under the second channel, after receiving the frequency hopping command, the terminal device may return the frequency hopping response to the terminal device under the second channel, and after receiving the frequency hopping response, the gateway device may confirm that the terminal device has completed switching between the working channel and the working rate.

The gateway device will now be described by way of an embodiment shown in fig. 7, how it determines a target terminal device from all terminal devices connected to it, for which a file upgrade is to be performed.

Referring to fig. 7, a process for implementing step 303 according to an exemplary embodiment of the present application includes the following steps:

step 701: and the gateway equipment sends an upgrade starting instruction to all connected terminal equipment under the second channel so that the terminal equipment receiving the upgrade starting instruction determines whether to upgrade according to the upgrade starting instruction.

Step 702: the gateway device receives an upgrade response message on the second channel, where the upgrade response message is used to indicate that an upgrade needs to be performed.

Step 703: the gateway device determines the terminal device sending the upgrade response message as the target terminal device for executing the file upgrade.

The following collectively describes steps 701 to 703:

since the gateway device has switched the working channel from the current first channel to the second channel after performing step 302, the gateway device may send an upgrade initiation instruction to all terminal devices connected under the second channel in step 701. After receiving the upgrade starting instruction, the terminal equipment can determine whether to upgrade according to the upgrade starting instruction, and after determining to upgrade, returns an upgrade response message for indicating that the upgrade needs to be executed to the gateway equipment. The gateway device may then determine the terminal device sending the upgrade response message as the target terminal device for performing the file upgrade.

As to how the terminal device determines whether to upgrade according to the upgrade initiation instruction, the following is illustrated by way of example, and is not repeated here.

Thus, the description of the flow shown in fig. 7 is completed.

By the flow shown in fig. 7, the gateway device determines the target terminal device to be subjected to file upgrade from all the connected terminal devices. Because the target terminal equipment is the terminal equipment which needs to execute the file upgrading, the success rate of the terminal equipment for executing the file upgrading can be improved.

The following describes how the gateway device sends an upgrade instruction to the target terminal device on the second channel by means of the embodiment shown in fig. 8:

referring to fig. 8, a process for implementing step 303 according to an exemplary embodiment of the present application includes the following steps:

step 801: the gateway device sends a first message carrying an upgrade file under a second channel.

As an example, the gateway device may first compare the size of the upgrade file with the set threshold, and if the comparison results in the size of the upgrade file being greater than the set threshold, the upgrade file may be divided into a plurality of upgrade packages, and the first message carrying the upgrade packages may be sequentially transmitted under the second channel. Through the processing, the phenomenon of file damage or file packet loss caused by oversized file sent at a time can be avoided.

As one example, the data size of each upgrade package does not exceed a set threshold.

Step 802: after the gateway device sends the first message carrying the upgrade file, the gateway device sends a second message under a second channel, where the second message is used to indicate that the upgrade file has been sent, so that the target terminal device that receives the second message performs file upgrade according to the upgrade file.

As one example, after sending the upgrade file, the gateway device may send a second message on a second channel indicating that the file upgrade has been sent. After receiving the second message, the target terminal device can start to execute file upgrading according to the upgrading file.

As to how the target terminal device performs the file upgrade according to the upgrade file, the following is illustrated by way of example, and will not be described in detail here.

Thus, the description of the flow shown in fig. 8 is completed.

Through the flow shown in fig. 8, it is finally achieved that the gateway device sends the upgrade instruction to the target terminal device under the second channel.

In addition, on the basis of the flow shown in fig. 8, after the step 802 is performed, the flow shown in fig. 9 may also be performed:

referring to fig. 9, a implementation flow after step 802 provided in an exemplary embodiment of the present application includes the following steps:

Step 901: and the gateway equipment sends an upgrade ending instruction to the target terminal equipment within a second set time after the second message is sent, so that the target terminal equipment which receives the upgrade ending instruction returns an upgrade result.

Step 902: and the gateway equipment receives an upgrade result returned by the target terminal equipment, and if the upgrade result indicates that the upgrade fails, the gateway equipment retransmits the upgrade file when the transmission times of the upgrade file are smaller than the set times, so that the target terminal equipment which fails to be upgraded is successfully upgraded.

The following collectively describes steps 901 and 902:

as an example, the gateway device may send an upgrade end instruction to the target terminal device after performing step 802. After receiving the upgrade ending instruction, the terminal equipment can return an upgrade result to the target terminal equipment. The upgrade result may be an upgrade result for indicating that the upgrade was successful, or an upgrade result for indicating that the upgrade failed to the user.

As an example, when the upgrade result is used to indicate upgrade failure, the upgrade result may also carry reasons for upgrade failure, such as lower upgrade file version, damaged upgrade file, missing upgrade file, etc.

As an embodiment, when the upgrade result is used to indicate upgrade failure, after receiving the upgrade result, the gateway device may further compare the number of times of sending the upgrade file with the set number of times, for example, 5 times, and when the number of times of sending the upgrade file is compared to be smaller than the set number of times, send the upgrade file to the target terminal device again under the second channel, so that the target terminal device with upgrade failure is successfully upgraded.

Thus, the description of the flow shown in fig. 9 is completed.

By the embodiment shown in fig. 9, since the upgrade file is repeatedly sent to the terminal device multiple times when the upgrade of the terminal device fails, the upgrade success rate of the terminal device can be improved.

So far, the related description of the file upgrading method provided by the application from the gateway equipment side is completed.

Secondly, the file upgrading method provided by the application is explained from the terminal equipment side:

referring to fig. 10, a flowchart of an embodiment of a method for upgrading a file according to another exemplary embodiment of the present application is provided, and in one example, the method may be applied to a terminal device, such as the terminal devices 140 to 160 illustrated in fig. 1.

As shown in fig. 10, the method comprises the following steps:

step 1001: the terminal equipment switches the working channel of the terminal equipment from the current first channel to the second channel according to the control of the gateway equipment, and switches the working rate from the current first rate to the second rate.

Based on the above embodiment of the gateway device side, the terminal device may switch the working channel from the current first channel to the second channel and switch the working rate from the current first rate to the second rate according to the control of the gateway device.

As one example, the terminal device may receive a frequency hopping command sent by the gateway device under the first channel, the frequency hopping command carrying a second channel identification and a second rate of the second channel. Based on the above, the terminal device can switch the working channel from the current first channel to the second channel corresponding to the second channel identifier according to the frequency hopping command, and switch the working rate from the current first rate to the second rate.

Step 1002: and the terminal equipment receives the upgrade instruction sent by the gateway equipment under the second channel. Step 1003: and the terminal equipment performs file upgrading according to the upgrading instruction.

Based on the above embodiment of the gateway device side, it can be seen that the upgrade instruction sent by the gateway device to the terminal device may carry an upgrade file. After receiving the upgrade instruction, the terminal device can execute file upgrade. As to how the terminal device performs file upgrade according to the upgrade instruction, the following is illustrated by way of example, and is not repeated here.

Thus, the description of the flow shown in fig. 10 is completed.

According to the embodiment, the terminal equipment switches the working channel from the current first channel to the second channel according to the control of the gateway equipment, switches the working rate from the current first rate to the second rate, then receives the upgrade instruction sent by the gateway equipment under the second channel, and performs file upgrade according to the upgrade instruction, so that batch upgrade of the terminal equipment can be realized, and different gateway equipment controls the terminal equipment connected with each other to perform file upgrade through different second channels, so that the phenomenon of signal interference can be effectively avoided.

In an embodiment, the terminal device may also perform the flow shown in fig. 11 before performing step 1002.

Referring to fig. 11, a implementation flow before step 1002 provided in an exemplary embodiment of the present application includes the following steps:

step 1101: and the terminal equipment receives the upgrade starting instruction sent by the gateway equipment under the second channel.

Based on the above embodiment of the gateway device side, the gateway device may first send an upgrade start instruction to all connected terminal devices on the second channel, so that the terminal device may receive the upgrade start instruction sent by the gateway device on the second channel.

As an example, the upgrade start instruction carries at least version information of an upgrade file (hereinafter referred to as first version information).

As one example, the upgrade initiation instruction also carries a file check parameter, such as a CRC check value, of the upgrade file.

As for the specific function of the upgrade initiation instruction carrying the file verification parameter, the following embodiments will be described in detail, which is omitted herein.

Step 1102: the terminal equipment compares the second version information and the first version information of the current program operation, and if the second version information is higher than or equal to the first version information, step 1104 is executed; if the second version information is lower than the first version information, step 1103 is executed.

Step 1103: and the terminal equipment compares the cached third version information with the first version information, and if the third version information is the same as the first version information, an upgrade response message is sent under a second channel to inform the gateway equipment that the terminal equipment needs to execute upgrade.

Step 1104: the terminal device determines that no upgrade is required.

The following collectively describes steps 1102 to 1104:

as an example, the terminal device may first compare version information of the current program operation (hereinafter referred to as second version information) with the first version information, and if the second version information is compared to be higher than or equal to the first version information, that is, the version of the current program operation is higher, the terminal device may determine that no upgrade is required.

Otherwise, if the second version information is not higher than the first version information, as an example, the terminal device may further check whether the upgrade file is cached, if so, the cached version information (hereinafter referred to as third version information) is compared with the first version information, and if the third version information is the same as the first version information, that is, the cached version is the same as the version of the upgrade, the reason for this may be that: an exception occurs during the last upgrade resulting in an upgrade suspension. At this time, the terminal device may transmit an upgrade response message under the second channel to inform the gateway device that the upgrade needs to be performed.

In addition, if the terminal device compares the third version information with the first version information, the terminal device may delete the cached upgrade file.

So far, the description of the flow shown in fig. 11 is completed.

Through the flow shown in fig. 11, it can be realized that the target terminal device for the current file upgrade to be executed is selected from all the terminal devices connected with the gateway device.

How the terminal device performs file upgrade according to the upgrade instruction is described below by way of an embodiment shown in fig. 12.

Referring to fig. 12, a process for implementing step 1003 according to an exemplary embodiment of the present application includes the following steps:

Step 1201: the terminal equipment detects whether the received upgrade file and file verification parameters meet the consistency requirement; if not, executing step 1205; if so, step 1202 is performed.

As can be seen from the above description, the upgrade start instruction also carries the file verification parameters of the upgrade file. Based on this, the terminal device may detect whether the received upgrade file and the file verification parameter meet the consistency requirement, if so, execute step 1202, and if not, consider that the received upgrade file is damaged, execute step 1205.

Step 1202: the terminal equipment detects whether a missing file exists in the received upgrade file, if not, the step 1203 is executed; if so, step 1204 is performed.

Based on the above embodiment of the gateway device side, the gateway device may divide the upgrade file into a plurality of upgrade packages and sequentially transmit the upgrade packages to the terminal device. Based on the above, the terminal device can detect whether the packet sequence numbers of the received upgrade packets are continuous, and if the packet sequence numbers are detected to be continuous, it can be determined that the received upgrade files have no missing files; if a discontinuity in the packet sequence number is detected, it may be determined that there is a missing file in the received upgrade file, and step 1204 is performed.

As an example, the missing file is an upgrade package corresponding to a package number of the discarded upgrade package.

As an example, the missing file may also be an upgrade package that is lost during the transfer.

Step 1203: and the terminal equipment performs file upgrading according to the received upgrading file.

Step 1204: the terminal equipment requests the gateway equipment to resend the missing file until the missing file in the upgrade file is received, and the file is upgraded according to the received upgrade file; ending the flow.

As an example, the terminal device may request the gateway device to resend the missing file according to the packet sequence number of the recorded missing file, and after receiving the packet sequence number of the missing file, the terminal device may resend the upgrade packet with the packet sequence number.

Step 1205: the upgrade file is discarded.

As an example, if the terminal device receives an upgrade packet divided from the upgrade file, the terminal device may further record the packet number of the discarded upgrade packet, so that the terminal device may request the gateway device to resend the missing file in step 1204.

Thus, the description of the flow shown in fig. 12 is completed.

Through the flow shown in fig. 12, the terminal device performs file upgrade according to the upgrade instruction.
