By the scheme, remote firmware upgrading can be performed on a machine-to-machine (M2M) terminal adopting a Zigbee technology under the condition of less modification.
Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a network system for implementing remote upgrading of Zigbee devices.
Background
Machine-to-Machine Communications (M2M) is a networked application and service with Machine intelligent interaction as a core, and data communication without manual intervention is realized by embedding a wireless or wired communication module and application processing logic in a Machine, so as to meet the informatization requirements of users on monitoring, command scheduling, data acquisition and measurement and the like. Fig. 1 shows a typical M2M system architecture, in which various M2M terminals (such as sensors, microcontrollers, etc.) are connected to an M2M gateway through a sensor network technology, and are connected to an M2M service platform through an M2M gateway by using a remote access technology (such as a 2G/3G wireless cellular network technology, an Asymmetric Digital Subscriber Line (ADSL) technology), and various applications (such as power meter reading, smart traffic, etc.) acquire data collected by the M2M terminal through an M2M service platform or remotely control and manage the M2M terminal.
Remote device management is an important function of the M2M system, and refers to that an M2M application or M2M service provider needs to perform daily management and maintenance on an M2M terminal in a peripheral sensor network remotely through an M2M service platform and an M2M gateway, and specifically includes functions of remote configuration management, performance management, fault management, software/firmware upgrade and the like on the M2M terminal. These device management functions need to be performed cooperatively by the M2M service platform and the device management capability component in the M2M gateway.
In the prior art, the remote Device Management technology based on the wan mainly includes a Device Management (DM) specification (hereinafter, referred to as DM) defined by Open Mobile Alliance (OMA), and a TR069 specification (hereinafter, referred to as TR069) defined by Broadband Forum (Broadband Forum). Among them, DM is mainly used in mobile network environment (such as 2G/3G cellular network), and TR069 is mainly used in fixed broadband network environment (such as ADSL), both of which can provide remote management and maintenance function for single device. In the sensing network, currently, a technology commonly used by the M2M terminal is a Zigbee technology, which not only provides basic communication capability between devices in the local sensing network, but also provides a certain device management capability, such as firmware upgrade (Zigbee otampropade). The Zigbee technology supports simultaneous firmware upgrade operations on multiple Zigbee network devices, and also provides multiple firmware upgrade execution modes.
Now, the device management capability component in the M2M service platform can remotely manage the M2M gateway using the remote device management technology (DM or TR069) based on the wide area network; the device management capability component in the M2M gateway may locally manage the M2M terminal of the sensor network tip by using the sensor network device management technology (Zigbee). However, due to the difference between the remote device management technology of the wan and the sensor network device management technology, M2M application or M2M service provider cannot directly manage the M2M terminal through the M2M service platform and the M2M gateway by using the wan-based device management technology.
The prior art provides a method for remotely managing an M2M terminal by using a Simple Network Management Protocol (SNMP) protocol, as shown in fig. 2, wherein a management application module on an SNMP management station sends a device upgrade request to a SNMP Agent on an Access Point (AP) through the SNMP protocol, the device upgrade request is forwarded to the SNMP Agent on the M2M terminal, and the SNMP Agent on the M2M terminal performs information interaction with a locally established SNMP Management Information Base (MIB), thereby implementing firmware upgrade on the M2M terminal.
The prior art has the following disadvantages:
in the prior art, an SNMP Agent and an SNMP Management Information Base (MIB) are required to be arranged on an M2M terminal, that is, an M2M terminal is required to support an SNMP protocol, but a large number of M2M terminals which are already applied to a sensor network do not support the SNMP protocol, so that when firmware needs to be updated, the existing M2M terminal is greatly changed, and operation cost is increased.

● Policy: the specific strategy for recording firmware version recovery at least comprises one of the following possible values:
-All: if the firmware of one device fails to be upgraded, all Zigbee devices (namely Zigbee devices which are recorded in the AplyTo node and meet the filtering condition) related to the firmware upgrade are restored to the firmware version before the firmware upgrade;
-Failed: if the firmware of the equipment fails to be upgraded, only the Zigbee equipment which fails to be upgraded is restored to the firmware version before being upgraded;
-None: any firmware version reply operation is not performed, and the subsequent operation instruction of the device management server is reported.
It should be noted that the above management tree model for Zigbee device firmware upgrade is only a typical example, where a specific node may change its relative position or name in the management tree in actual deployment (e.g., DevList may be directly connected below the root node./without going through the./GW node, and nodes for storing respective firmware information may also be directly connected below the root node./or other nodes). In addition, for a plurality of executable nodes which represent a plurality of upgrading modes and are defined under the nodes of < x >/Download/operation and < x >/deleted/operation, a single executable node can be matched with a plurality of related attribute node descriptions to distinguish different execution modes (similar to the design principle of the nodes of < x >/recovery).
Referring to fig. 5, an embodiment of the present invention provides a method for implementing remote upgrading of a Zigbee device, where a DM protocol is used between a device management server and a gateway, and the method specifically includes:
501. the Zigbee device determines the gateway in the local network that manages it.
Specifically, there may be two ways:
the first mode is as follows: the Zigbee device is configured with IEEE addresses of gateways in advance (each IEEE address uniquely identifies one gateway), the Zigbee device determines that the gateway identified by the IEEE address is a gateway for managing itself, and the Zigbee device may also send a Zigbee device object network address request ZDO Nwk _ addr _ req according to the IEEE address, and acquire a network address of the gateway from a received response message, so as to perform management information interaction with the gateway later using the network address.
The second mode is as follows: if the IEEE address of the gateway is not preconfigured in the Zigbee device, an object matching description request ZDO Match _ Desc _ req request is broadcast to the local network, where the object matching description request ZDO Match _ Desc _ req request carries a firmware upgrade Cluster identifier OTA Cluster ID, where the identifier indicates that a gateway supporting a Zigbee firmware upgrade function is searched, and after receiving the request, the gateway in the local network sends an object matching description response ZDO Match _ Desc _ rsp message to the Zigbee device, where the object matching description response ZDO Match _ Desc _ rsp message carries a network address of the gateway.
502. The gateway obtains detailed information of Zigbee devices using Zigbee device management commands in order to configure information on/GW./DevList nodes in the management tree as shown in fig. 4.
Specifically, the gateway sends a device information query request message to the Zigbee device, for example, a Zigbee device object Node description request ZDO Node _ Desc _ req, a Zigbee device object Simple description request ZDO Simple _ Desc _ req message, and the like, for requesting to acquire detailed information of the Zigbee device; the Zigbee device sends a response message to the gateway, where the response message carries device description information such as a manufacturer identifier, a device type, and the like of the Zigbee device. The gateway sends a Zigbee cluster library attribute reading ZCL Read _ Attributes request message to the Zigbee equipment, wherein the message carries a Current firmware version parameter to request to query the firmware version of the Zigbee equipment; the Zigbee device sends a response message to the gateway, where the response message carries the firmware version information of the Zigbee device.
503. The gateway configures the detailed information of the Zigbee devices into relevant nodes of the management tree, specifically, into DevList nodes under GW as in the MO management tree shown in fig. 4.
504. The gateway establishes a device management session with a device management server using a remote device management protocol.
Specifically, the gateway receives a device management notification message from a device management server, then establishes a device management session with the device management server, and provides basic information (/ information recorded in a devlnfo node) of the gateway itself to the device management server by replacing a Relplace command; the device management server obtains the detailed information of the gateway (./information recorded in a DevDetail node) and the information of all Zigbee devices connected to the gateway (./information recorded in a GW/DevList/node) by obtaining a Get command.
505. The device management server configures basic information of the new firmware and range description information of the Zigbee device to which the new firmware is applicable in a relevant node of the gateway management tree through a Replace command.
Specifically, a new firmware name is configured in the PkgName node, a version is configured in the pkversion node, and Zigbee device range description information to which the new firmware is applicable is configured in the ApplyTo.
506. And the equipment management server performs remote firmware upgrading operation on the Zigbee equipment through the gateway by using the established equipment management session.
Please refer to the detailed description of the following embodiments.
It should be noted that, since the remote device management protocol (DM/TR069) and the Zigbee protocol are not completely compatible in parameter naming and data type, in step 503, when the gateway configures the detailed information of the Zigbee device to the relevant node of the management tree, it needs to perform a conversion operation of parameter Name and data type, and table 1 lists a conversion mapping relationship of parameters that need to be supported by firmware upgrade, where a Uniform Resource Name (URN) is a specific string type with a specially defined format.
TABLE 1
Fig. 6 shows a manner in which the device management server implements remote upgrading of Zigbee devices through a gateway, that is, a common upgrading manner, where the common upgrading manner is that each Zigbee device is upgraded immediately after obtaining a new firmware, and is unrelated to the upgrading time of other Zigbee devices suitable for the new firmware, and specifically includes:
601. the equipment management server controls the gateway to download the new firmware and triggers the gateway to execute an executable command which represents that the firmware is distributed on the nodes in the management tree and the Zigbee equipment is immediately upgraded after the distribution.
In steps 501 to 504 in the above embodiment, the gateway configures information of Zigbee devices managed by the gateway, and the device management server establishes a management session for remote firmware upgrade of Zigbee devices through the gateway, and configures basic information of a new firmware and a Zigbee device range to which the new firmware upgrade is applicable in the gateway. In this step, the device management server may determine to remotely upgrade the Zigbee device in a normal upgrade manner according to the Zigbee device information under the gateway and the influence of the new firmware on the current Zigbee network and application.
The steps specifically comprise the following implementation modes:
the first mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in a direct downloading mode. The device management server directly writes the new firmware into a Zigbee Fw/< x >/deleted/PkgData node of the gateway through a Replace command, and triggers the gateway to execute an executable command on the Zigbee Fw/< x >/deleted/Operations/Updrade node.
The second mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in an indirect downloading mode. The equipment management server directly writes the Download address of the new firmware into a ZigbeFw/< x >/Download/PkgURL node of the gateway management tree through a Replace command; the device management server instructs the gateway to Download the new firmware from the Download address by triggering the gateway to execute an executable command on the Zigbee fw/< x >/Download/Operations/Download update node, and then immediately executes a firmware upgrade operation on the Zigbee device to which the new firmware is applicable, wherein the gateway may Download the new firmware from the Download address on the Zigbee fw/< x >/Download/PkgURL node by using a file transfer protocol or other Download protocols.
The third mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in an indirect downloading mode. The equipment management server directly writes the Download address of the new firmware into a Zigbee Fw/< x >/Download/PkgURL node of the gateway through a Replace command; the equipment management server instructs the gateway to Download the new firmware by triggering the gateway to execute an executable command on a Zigbee Fw/< x >/Download/Operations/Download node; the gateway downloads the new firmware from a Download address on a Zigbee Fw/x/Download/PkgURL node by adopting a file transfer protocol or other Download protocols, and reports the success of downloading the new firmware to the equipment management server; the device management server instructs the gateway to immediately execute firmware upgrading operation on the Zigbee device suitable for the new firmware by triggering the gateway to execute the executable command on the Zigbee Fw/< x >/deleted/Operations/Updide node.
602. The gateway executes an executable command which indicates that the firmware is distributed on the nodes in the management tree and immediately upgrades the Zigbee equipment after the firmware is distributed, and distributes the new firmware to the Zigbee equipment which is suitable for the new firmware by adopting the existing Zigbee firmware downloading technology according to the Zigbee equipment range description information which is recorded by the nodes in the management tree and is suitable for upgrading the new firmware and the information of each Zigbee equipment managed by the gateway.
Specifically, the gateway may send an Image notification Image Notify message to all Zigbee devices by using a broadcast message, where the Image notification message carries application range description information of the new firmware, and the method specifically includes: and at least one of an applicable Zigbee device model and a device manufacturer identifier of the new firmware. If the equipment management server writes the type identifier of the Zigbee equipment suitable for firmware upgrade, the maximum version number of the current old firmware of the Zigbee equipment capable of upgrading, or the minimum version number of the current old firmware of the Zigbee equipment capable of upgrading, because the Image Notify message itself cannot carry the above information, the gateway determines the Zigbee equipment suitable for new firmware according to the information of each Zigbee equipment stored on the management tree node, and sends the Image Notify message to the determined Zigbee equipment in a unicast manner, where the Image Notify message is used to Notify the Zigbee equipment to download new firmware. In this step, when sending the Image Notify message to the Zigbee device by using a broadcast message or a unicast message, the conversion operation of the parameter name and the data type needs to be performed with reference to table 1, which is not described herein again.
After receiving the Image Notify message, the Zigbee device determines whether the Zigbee device needs to perform firmware upgrade according to whether the Zigbee device is a unicast message or not and according to the application range description information of the new firmware carried in the Image Notify message when the Zigbee device is not a unicast message, and if the Zigbee device is not a unicast message, sends a Query Next Image Request to the gateway to Request to acquire the new firmware, where the message carries information such as the device model of the Zigbee device (i.e., information stored on the mod node in the management tree), the device manufacturer identifier (i.e., information stored on the man node in the management tree), and the current firmware version number. The gateway sends the size of the new firmware and the size of the downloaded blocks to the Zigbee equipment, and the Zigbee equipment downloads the new firmware from the gateway according to the size of the new firmware and the size of the downloaded blocks.
603. The gateway instructs the Zigbee device to immediately perform a firmware upgrade.
Specifically, the gateway sends an Upgrade End Response message to each Zigbee device that has successfully downloaded the new firmware, where the Upgrade End Response message carries a parameter indicating that the Zigbee device immediately upgrades the new firmware.
Fig. 7 shows a manner in which the device management server implements remote upgrading of Zigbee devices through a gateway, that is, a manner of controlling synchronous upgrading of Zigbee devices, specifically including:
701. the equipment management server controls the gateway to download the new firmware and triggers the gateway to execute an executable command which represents the distribution of the firmware on the nodes in the management tree and synchronously updates the Zigbee equipment after the distribution.
The executable command is an indication indicating that firmware distribution and synchronous firmware upgrade are performed after all Zigbee devices successfully download new firmware.
In this step, the device management server determines, according to the Zigbee device information under the gateway and the influence of the new firmware on the current Zigbee network and application, that the firmware upgrade process of each Zigbee device may affect each other on communication or application of the Zigbee local network, so that each Zigbee device needs to perform upgrade at the same time, and thus it is determined that the Zigbee device under the gateway is remotely upgraded in a synchronous upgrade manner.
The steps specifically comprise the following implementation modes:
the first mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in a direct downloading mode. The equipment management server directly writes the new firmware into a Zigbee Fw/< x >/Delivered/PkgData node of the gateway through a Replace command, triggers the gateway to execute an executable command on the Zigbee Fw/< x >/Delivered/Operations/UpdegraSync node, and instructs the gateway to control the Zigbee equipment suitable for the new firmware to synchronously execute firmware upgrading operation.
The second mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in an indirect downloading mode. The equipment management server directly writes the Download address of the new firmware into a Zigbee Fw/< x >/Download/PkgURL node of the gateway through a Replace command; the device management server instructs the gateway to Download the new firmware from the Download address by triggering the gateway to execute the executable command on the Zigbee Fw/< x >/Download/Operations/Download upgrade Sync node, and then immediately controls the Zigbee device to which the new firmware is applicable to execute the synchronous upgrade operation. The gateway may Download the new firmware from a Download address on the zigbee fw/< x >/Download/pkggurl node using a file transfer protocol or other Download protocols.
The third mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in an indirect downloading mode. The equipment management server directly writes the Download address of the new firmware into a Zigbee Fw/< x >/Download/PkgURL node of the gateway MO through a Replace command; the equipment management server instructs the gateway to Download the new firmware by triggering the gateway to execute an executable command on a Zigbee Fw/< x >/Download/Operations/Download node; the gateway downloads the new firmware from a Download address on a Zigbee Fw/x/Download/PkgURL node by adopting a file transfer protocol or other Download protocols, and reports the success of downloading the new firmware to the equipment management server; the device management server instructs the gateway to control the Zigbee device to which the new firmware is applicable to synchronously execute firmware upgrading operation by triggering the gateway to execute the executable command on the Zigbee Fw/< x >/deleted/Operations/Updegrasync node.
702. The gateway executes an executable command which represents that the firmware is distributed on the nodes in the management tree and synchronously upgrades the Zigbee equipment after the distribution, and distributes the new firmware to the Zigbee equipment which is suitable for the new firmware by adopting the existing Zigbee firmware downloading technology according to the Zigbee equipment range description information which is recorded by the nodes in the management tree and is suitable for upgrading the new firmware and the information of each Zigbee equipment managed by the gateway.
703. The gateway instructs the Zigbee device to perform a synchronous firmware upgrade.
Specifically, the gateway sends an Upgrade End Response message to each Zigbee device that is suitable for the new firmware, where the Upgrade message carries information indicating that the Zigbee device does not perform the firmware Upgrade operation temporarily; the gateway sends a ZCL Read _ Attributes message to each Zigbee device which is suitable for new firmware so as to obtain a new firmware downloading state of each Zigbee device, and after determining that all Zigbee devices successfully download the new firmware, the gateway simultaneously sends a Run Updide Request message to each Zigbee device, wherein the RunUpdide Request message carries a parameter indicating that the Zigbee devices are immediately upgraded to the new firmware.
Currently, a certain Zigbee device suitable for new firmware is in a dormant state, and cannot receive and execute a related Upgrade command, so in this step, the gateway selects a time when all Zigbee devices suitable for new firmware are in an active state according to locally recorded information of each Zigbee device suitable for new firmware, and sends Run update Request messages to the Zigbee devices in the active state, where the time carries indication information indicating that firmware Upgrade is performed at the selected time point; or, the gateway selects a time point, and sends, to the Zigbee device when the Zigbee device is in the active state, indication information indicating that firmware upgrade is performed at the selected time point, and if the Zigbee device is in the dormant state at the selected time point, the Zigbee device adjusts the dormant time to ensure that the Zigbee device is in the active state at the time point, and a subsequent execution process is the same as step 803 in the embodiment shown in fig. 8.
Fig. 8 shows a manner in which the device management server implements remote upgrading of a Zigbee device through a gateway, that is, a manner of controlling a Zigbee device to be upgraded at a fixed time specifically includes:

The third mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in an indirect downloading mode. The equipment management server directly writes the Download address of the new firmware into a Zigbee Fw/< x >/Download/PkgURL node of the gateway through a Replace command, and writes the preset upgrade time into a Zigbee Fw/< x >/deleted/Operations/updated/UTCTime node, or writes the time offset relative to the current into the Zigbee Fw/< x >/deleted/Operations/updated/offset time node; the equipment management server instructs the gateway to Download the new firmware by triggering the gateway to execute an executable command on a Zigbee Fw/< x >/Download/Operations/Download node; the gateway downloads the new firmware from the Download address on the zigbee fw/< x >/Download/pkggurl node by adopting a file transfer protocol or other Download protocols, and reports the success of downloading the new firmware to the device management server. The device management server triggers the gateway to execute the executable command on the Zigbee fw/< x >/deleted/Operations/upgrade scheduled node, so that the gateway controls the Zigbee device suitable for the new firmware to execute the firmware upgrade operation at the specific upgrade time.
802. And the gateway executes an executable command which indicates that the firmware is distributed on the nodes in the management tree and the Zigbee equipment is upgraded in the preset upgrading time after the firmware is distributed, and distributes the new firmware to the Zigbee equipment suitable for the new firmware by adopting the existing Zigbee firmware downloading technology according to the Zigbee equipment range description information which is recorded by the nodes in the management tree and suitable for upgrading of the new firmware and the information of each Zigbee equipment managed by the gateway.
803. The gateway instructs the Zigbee device to perform firmware upgrade at a predetermined upgrade time.
The steps are concretely realized in the following ways:
the first mode is as follows: the gateway sends an Upgrade EndResponse message to each Zigbee device suitable for the new firmware, wherein the Upgrade time parameter carries an Upgrade time parameter, and the Upgrade time parameter indicates the specific time of the Zigbee device for firmware Upgrade, which can be an absolute time value or a relative current time value, and does not influence the implementation of the invention.
The second mode is as follows: the gateway sends an Upgrade EndResponse message to each Zigbee device applicable to the new firmware, wherein the Upgrade message carries information indicating that the Zigbee device does not execute the firmware upgrading operation temporarily; the gateway sends a Zigbee cluster library attribute reading ZCLRead _ Attributes message to each Zigbee device needing to be upgraded so as to obtain a new firmware downloading state of each Zigbee device, and after all the Zigbee devices needing to be upgraded are determined to successfully download new firmware, a Run Updide Request message is sent to all the Zigbee devices needing to be upgraded, wherein the update time parameter is carried.
Fig. 9 illustrates a manner in which the device management server implements remote upgrading of Zigbee devices through a gateway, where the manner is to distribute new firmware to the Zigbee devices first, and then trigger the Zigbee devices to control each Zigbee device to perform firmware upgrading in a normal upgrading manner, a synchronous upgrading manner, or a timing upgrading manner, and the method specifically includes:
901. the device management server downloads the new firmware to the gateway and triggers an executable command on the gateway indicating the distribution of the new firmware.
The steps are concretely realized in the following ways:
the first mode is as follows: the method is suitable for the device management server to download the new firmware to the gateway in a direct downloading mode. The device management server directly writes the new firmware into a Zigbee Fw/< x >/deleted/PkgData node of the MO of the gateway through a Replace command, triggers the gateway to execute an executable command on the Zigbee Fw/< x >/deleted/Operations/distribution node, and instructs the gateway to execute firmware distribution operation on the Zigbee device suitable for the new firmware.

903. The gateway sends a message indicating that the firmware upgrade operation is not executed for a while to each Zigbee device to which the new firmware is applicable.
Specifically, the gateway sends an Upgrade End Response message to each Zigbee device that is suitable for new firmware, where the Upgrade message carries information indicating that the Zigbee device does not perform firmware Upgrade operation temporarily.
904. The gateway queries each Zigbee device that is suitable for the new firmware download status.
Specifically, the gateway sends a ZCL Read _ Attributes message to each Zigbee device that is suitable for new firmware, and requests to obtain a new firmware download state of each Zigbee device.
905. The gateway reports the distribution condition of the new firmware, that is, the firmware download result of the Zigbee device to which the new firmware is applicable, to the device management server according to the new firmware download state of each Zigbee device.
Specifically, the distribution of the new firmware is reported to the device management server by sending an Alert command.
906. And the equipment management server determines a firmware upgrading mode of the Zigbee equipment according to the distribution condition of the new firmware and the influence of the new firmware on the Zigbee equipment and the network, and triggers the gateway to execute an executable command of the determined firmware upgrading mode on the node in the management tree.
The equipment management server determines whether the Zigbee equipment needs to be upgraded according to the distribution condition of the new firmware, and then determines the specific firmware upgrading mode of the Zigbee equipment according to the distribution condition of the new firmware and the influence of the new firmware on the Zigbee equipment and the network.

Optionally, the device management server may re-determine a range of the Zigbee device to which the new firmware is applicable according to a distribution condition of the new firmware and an influence of the new firmware on the Zigbee device and the network, and re-notify the gateway, and the subsequent gateway executes the executable command under the trigger of the device management server, and sends a message indicating upgrading to the re-determined Zigbee device to which the new component is applicable.
It should be noted that, in step 505 of the foregoing embodiment, the device management server may further configure, through a Replace command, a firmware recovery Policy when the Zigbee device fails to be upgraded on a < x >/recovery/Policy node of the management tree, specifically, may be configured as "All" or "Failed", or may be configured as "None", where when configured as "None", it indicates that a specific firmware recovery Policy is not currently configured, and it is necessary for the gateway to send upgrade result information to the device management server, and the device management server reconfigures the specific firmware recovery Policy according to the upgrade result information, and after the Zigbee device that is applicable to the new firmware performs the upgrade operation, the method further includes:

Specifically, the gateway may send a Zigbee cluster library attribute read ZCLRead _ Attributes request message to the Zigbee device, where the Zigbee cluster library attribute read ZCLRead _ Attributes request message carries a currentfirmware version parameter indicating that the gateway requests to acquire a latest firmware version number of the Zigbee device, and the Zigbee device sends a response message carrying the latest firmware version number of the Zigbee device to the gateway, and the gateway may determine whether the Zigbee device is successfully upgraded according to the latest firmware version number, and record Zigbee fw/< x >/State/successful list and/or Zigbee fw/< x >/State/fault list according to a determination result, or immediately update Zigbee device version information under GW/DevList/node.
1002. When the Policy node is None, it indicates that there is no firmware recovery Policy currently, and the gateway reports an upgrade result of the Zigbee device to the device management server through an Alert command, where the upgrade result status information is carried, and the upgrade result status information may indicate that all/part of the Zigbee device succeeds, all/part of the Zigbee device fails, and the like. When the Policy node is configured as "All" or "Failed", step 1006 is performed.
1003. The device management server obtains the detailed upgrade status information under the zigbee fw/< x >/State node (for example, obtains the information recorded on the zigbee fw/< x >/State/Value, and/or < x >/State/FailedList, and/or zigbee fw/< x >/State/success list node) from the gateway management tree through the Get command.
Optionally, if the gateway updates the firmware version information of the Zigbee device under the te/GW/DevList/node in time, the device management server may also obtain the update result by reading the firmware version information under the te/GW/DevList/node.
1004. The equipment management server reconfigures the firmware recovery strategy to be All or Failed according to the acquired detailed upgrading state information through the Replace command at the < x >/Recover/Policy node in the gateway management tree.
Specifically, the firmware recovery policy may be reconfigured to be All or Failed according to the acquired detailed upgrade status information and a policy preset by the device management server, or may be reconfigured to be All or Failed according to an operation instruction of an administrator.
1005. The device management server triggers an executable command on the < x >/recovery node in the gateway.

The gateway executes an executable command on the < x >/recovery node, when a firmware recovery Policy on the < x >/recovery/Policy node is All, a firmware recovery command is sent to All Zigbee equipment suitable for the new firmware, and when the firmware recovery Policy is Failed, a firmware recovery command is sent to Zigbee equipment Failed in upgrade, wherein the firmware recovery command is used for indicating the Zigbee equipment to Recover and use the firmware before upgrade.
1007. The gateway queries the current version number of the Zigbee device receiving the firmware recovery command, and determines whether the Zigbee device has recovered to the version before the upgrade.
Specifically, the process of querying a current version number of the Zigbee device that receives the firmware recovery command includes: the gateway may send a ZCL Read _ Attributes request message to the Zigbee device, where the ZCL Read _ Attributes request message carries a currentfirmware version parameter, where the parameter indicates that the gateway requests to acquire the latest firmware version number of the Zigbee device, and the Zigbee device sends a response message carrying the latest firmware version number of the Zigbee device to the gateway.
1008. The gateway sends a firmware recovery result to the device management server through the Alert command, where the firmware recovery result may be that each Zigbee device is successfully recovered, or that a Zigbee device that fails to be upgraded has been successfully recovered.
1009. And the equipment management server sends an equipment management termination command Final to the gateway and ends the equipment management session.
The above embodiments are described with the DM protocol used between the device management server and the gateway, and the TR069 protocol may also be used between the device management server and the gateway. The TR069 protocol and the DM protocol have great similarities in the interaction mechanism between the device management server and the gateway and the design of the data structure of the management tree, and implement the function of remote device management by establishing a remote device management session between the device management server and the gateway and operating the data of the nodes in the gateway management tree in the session, and the main differences are as follows: nodes in the TR069 protocol have no executable property, that is, the gateway cannot be instructed to execute corresponding Operations by triggering an executable command on a certain node (such as zigbee fw/< x >/Download/Operations/Download). In order to instruct the gateway to perform corresponding operations, the TR069 protocol carries a series of dedicated device management commands (e.g., Download, rebot.) in the device management message or encapsulates them in a new firmware file downloaded by the gateway. Fig. 11 is a structure of a downloaded file supported by the TR069 protocol, where when the file is used to encapsulate a new firmware to be upgraded, a device management command list related to the file may carry a series of descriptions and commands related to device firmware upgrade, where the descriptions and commands include file usage, firmware version information, an applicable device version range, and the like, and the new firmware file may be expanded to further include a Zigbee device range command applicable to the new firmware, a new firmware upgrade mode command, and the like.
Referring to fig. 12, an embodiment of the present invention provides a method for implementing remote upgrading of a Zigbee device, in the method, a TR069 protocol is used between a device management server and a gateway, and the method specifically includes:
1201-1203 are the same as 501-503.
1204. The gateway establishes a device management session with the device management server using the TR069 protocol.
Specifically, the device management server sends a device management notification message ConnectionRequest to the gateway, the gateway establishes a device management session with the device management server according to the message, and provides basic device information of the gateway through a DeviceId parameter in an Inform command, wherein the basic device information specifically includes information such as a Manufacturer identifier (Manufacturer), a device identifier (SerialNumber), a device model (ProductClass), and the like; the device management server may further obtain detailed device information of the gateway (./information on DevDetail node) and information on all Zigbee device managed by the gateway (./information on GW/DevList node) through a get parameter value GetParameterValues command.
Optionally, the gateway may also actively provide the device management server with the basic device information and the detailed device information of the gateway itself.
1205. The device management server configures new firmware information on the zigbee fw/< x > node in the gateway by setting the parameter value SetParameterValues command.
If a zigbee fw/< x > node has not been created in the gateway, the device management server may create the node by adding an object AddObject command.
