In order to improve the success rate of the device upgrade, the embodiment provides multiple methods for upgrading the device, and improves multiple upgrade links, thereby improving the success rate of the device upgrade. As the first method is to make the user device The version file is downloaded from a file server with a small number of user devices. This method balances the load of the file server and prevents the file server from being corrupted, so that the user device can successfully download the version file from the file server and upgrade. For example, the second method is to enable the user equipment to perform an upgrade operation after the startup, the method can avoid the upgrade when the user needs to use the user equipment, that is, the normal service, and can avoid the failure of the user equipment when the upgrade fails during startup. For example, the third method is to enable the user equipment to perform an upgrade operation when idle. This method can avoid upgrading when the user needs to use the user equipment, that is, use normal services, and can prevent the network from providing sufficient bandwidth for multiple users. The upgrade failed because the device was upgraded concurrently. This embodiment also provides a preferred method, that is, a combination of the above three methods. The embodiment also provides a method for the user to randomly select a file server and download a version file, and the load of the file server can be balanced, and the network side does not need to perform an upgrade decision to reduce the burden on the network side.

Referring to FIG. 1A, the communication system in this embodiment includes a user equipment 101, a network management server 102, an upgrade policy server 103, and a file server 104.

The file server 104 stores files of various versions (including data for upgrading devices) and files including version information. There may be multiple file servers 104, which are divided according to factors such as device type, manufacturer, product model, and region. A file server 104 can store only the version files related to the A service of the Type A device of the Type A produced by the manufacturer A, and can also store all the version files.

The user equipment 101 may be one or more devices that directly provide services to users. In order to better serve users, various configurations and services need to be upgraded. The user equipment 101 sends a handshake message to the network management server 102 at startup or periodically. The message includes its own version information, including the version number, and the version number includes the product information of the user equipment 101 (including the device type, vendor, and product). Information such as the model number and the current version file (including the identification of the version file, etc.). Among them, device types such as mobile phones and personal computers. When receiving the information of the file server 104, it is determined whether there is currently a service being processed, especially a service that cannot be synchronized with the upgrade, such as a call service, and if so, the upgrade operation is suspended, and the upgrade is continued after the service is finished, otherwise Performing an upgrade operation, downloading the latest version from the specified file server 104 according to the file server 104 information. And notify the network side that the upgrade has begun. After the download version file is completed, upgrade the configuration and notify the network side that the download is complete. The user equipment 101 needs to perform a restart operation when performing some upgrade operations to make the new version file take effect.

The network management server 102 manages each device in the network. The network management server 102 extracts the version number from the received handshake message and transmits the version number to the corresponding upgrade policy server 103.

The upgrade policy server 103 is configured to perform an upgrade policy scheduling, which may be one or more, and is used to compare whether the version number is consistent with the latest version number stored by the version number after receiving the version number, and determine whether the current upgrade period is allowed. If the version number sent by the user equipment 101 at the time of startup is received, it is further determined whether the user equipment 101 is allowed to be upgraded at the time of startup. When the above conditions are satisfied, the query is based on the correspondence between the version number and the file server 104. The file server 104 corresponding to the latest version number selects the file server 104 with a small number of user devices to be carried from the queried file server 104 according to the pre-defined upgrade policy, and transmits the information of the file server 104 to the user device 101. And, when the notification sent by the user equipment 101 that the upgrade has been started is received, the number of user equipments carried by the file server 104 is increased by one, and when the download end notification sent by the user equipment 101 is received, the file server 104 is carried. The number of user devices is decremented by one. The information about the file server 104 stored in the upgrade policy server 103 may be obtained through the web server, or interacted with the file server 104, or obtained by manual configuration. Further, the upgrade policy server 103 may be separately set according to factors such as device type, vendor, product model, and region. This step-by-step structure can better support a large number of user equipments 101 to be upgraded at the same time. When the network needs to be expanded, only a few upgrade policy servers 103 need to be added to the network and registered with the network management server 102, and no other equipment is needed. Make changes. In this embodiment, the upgrade policy server 103 is an independent entity as an example.

The above-mentioned pre-defined upgrade policies are various, for example, the threshold value of the number of user equipments that are set by the file server 104 according to the performance and bandwidth of the file server 104, and the upgrade policy server 103 queries the file server 104. When the number of the user equipments that are carried does not reach the threshold, the information of the file server 104 is sent to the user equipment 101, and the subsequent files need not be queried. The server 104; another preferred upgrade strategy is to set a threshold value of the number of user equipments carried by the file server 104 according to the performance and bandwidth of the file server 104, and the upgrade policy server 103 carries the files carried by the file servers 104. The number of user equipments is compared with the corresponding threshold value, and the information of the file server 104 with the smallest ratio is sent to the user equipment 101, so that the load of each file server 104 can be better balanced.

In the foregoing communication system, the upgrade policy server 103 that performs the upgrade policy scheduling is an independent entity; the upgrade policy server 103 can also be embedded in the network management server 102 as a function module, as shown in FIG. 1B, the communication in this embodiment The system includes a user device 101, a network management server 102, and a file server 104.

The file server 104 stores files of various versions and files including version information. There may be multiple file servers 104, which are divided according to factors such as device type, manufacturer, product model, and region. A file server 104 can store only version files of the A type A device produced by the manufacturer A in relation to the A service, and can also store all version files.

The user equipment 101 may be one or more devices that directly provide services to users. In order to better serve users, various configurations and services need to be upgraded. When the user equipment 101 starts or periodically sends a handshake message to the network management server 102, the message includes its own version information, and when receiving the information of the file server 104, it determines whether there is currently a service being processed, especially cannot be upgraded. Synchronous services, such as call service, if yes, suspend the upgrade operation, wait for the service to end, and then continue the upgrade. Otherwise, perform the upgrade operation, download the latest version file from the specified file server 104 according to the file server 104 information, and notify the network. The side has started to upgrade. After the download version file is completed, upgrade the configuration and notify the network side that the download is complete. The user device 101 needs to perform a reboot operation for some upgrade operations to make the new version file take effect.

The network management server 102 manages each device in the network. The network management server 102 extracts the version number from the received handshake message, compares the version number with the stored latest version number corresponding to the user equipment 101, and finds that the comparison result is inconsistent, and determines whether the current upgrade period is allowed. If the version number sent by the user device 101 at startup is received, then it is determined whether the permission is allowed. The user equipment 101 is upgraded at startup, and when the above conditions are satisfied, the file server 104 corresponding to the latest version number is queried according to the correspondence between the version number and the file server 104, and the file server 104 is queried according to the pre-defined upgrade policy. The file server 104 that selects a small number of user devices is selected, and the related information of the file server is returned to the user device 101. And, when the notification of the upgrade has been received, the number of the user equipments of the selected file server 104 is increased by one, and the number of the user equipments corresponding to the selected file server 104 is decreased by one when the notification of the completion of the download is received. .

The network management server 102 finds that the user equipment 101 is of the A type, and then selects the A type of the plurality of upgrade policy servers 103 that are responsible for the A zone. Upgrade the policy server 103.

Step 503: The upgrade policy server 103 compares the received version number with the latest version number of the locality. If the comparison result is consistent, the upgrade process is terminated, and the notification that the "already the latest version" is further sent to the user device 101, otherwise Proceed to step 504.

Step 504: The upgrade policy server 103 queries the file server 104 that stores the latest version file from the list of local file servers 104, and selects the file server 104 with a lower load rate. The specific method is as follows: Calculate the users carried by the file servers. The ratio of the number of devices to their threshold. The smallest ratio is selected from each ratio, and when it is determined that the minimum ratio is less than 1, the information of the file server 104 corresponding to the smallest ratio and the latest version number are sent to the user equipment 101, so that the user equipment 101 can connect to the file server 104. . Alternatively, the upgrade policy server 103 determines the ratio of the number of user equipments carried by the file server 104 whose number of user equipments is lower than the threshold value to the threshold value, selects the file server 104 corresponding to the smallest ratio, and selects the file. The information of the server 104 and the latest version number are transmitted to the user device 101. When the upgrade policy server 103 finds that the number of user equipments carried by all the file servers 104 reaches the threshold, the upgrade process is terminated, and the notification of "temporarily unable to upgrade" can be further sent to the user equipment 101.
