Description

Upgrade method, communication equipment and computer readable storage medium

Technical field

The present invention relates to the field of communication technology, and more specifically, to an upgrade method, a communication device, and a computer-readable storage medium.

Background technique

In the communication field, with the continuous development of communication technology, from 3G to 4G, and then to 5G technology, the software and hardware of communication equipment are constantly being updated and upgraded. At the same time, under the same technological background, such as the 4G era, the software and hardware of the equipment are constantly being upgraded and updated. In the same technological period, equipment upgrades may be mainly software upgrades, and software upgrades are currently classified in terms of their impact on services in two ways: interrupted service upgrades and uninterrupted service upgrades. The interrupted service upgrade is mainly because the two versions before and after the upgrade have incompatibility that cannot be solved. The uninterrupted service upgrade is realized by protection switching or CPU soft reset while ensuring the compatibility of the software before and after. However, if you deal with different technological eras, such as upgrading from 4G version to 5G version, in addition to software incompatibility, device hardware may also appear incompatible. For example, in the 5G era, in order to ensure higher download speeds and lower time Delay, need to support high-precision clock function, this will inevitably lead to the need to update the hardware.

On the other hand, when upgrading an existing network, operators always hope that the cost is minimal, and the previous device version can be used to achieve a smooth upgrade. Therefore, when the equipment is upgraded from supporting 4G functions to supporting 5G functions, operators hope to update only part of the equipment's single boards to realize both 4G services and 5G services, thereby saving costs to the greatest extent. Then, when the software and hardware of the equipment board are incompatible, how to achieve rapid equipment upgrade is a key technical problem that all equipment manufacturers must face. The usual upgrade method is to import the service configuration file of the original device to the new main control board, then replace the old main control board with the new main control board, and then restart the whole machine to achieve the upgrade. This method is complicated to operate. The service interruption time includes the start-up time of the new main control board, the new main control board resume service configuration time, the line card start time, etc. When there are many service configuration files, the new main control board resumes business time longer. The entire upgrade process will have a longer business interruption.

It can be seen that the operation of upgrading communication equipment in the related technology is complicated, and the service interruption time of the upgrading process is relatively long, and the upgrading efficiency is low.

It is also called the master main control board, and the other main control board serves as the protection main control board during abnormal operation, and is also called the standby main control board.

S101: Maintain the normal operation of the second main control board, and upgrade the first main control board.

Optionally, upgrading the first main control board in this embodiment includes: replacing the first main control board with the first new main control board.

It should be understood that since the second main control board is operating normally at this time, in other words, the second main control board at this time maintains normal inter-board communication with other boards, the second main control board will act as the master master The first new main control board serves as a backup main control board; among them, the first new main control board includes high-standard version files, and the first main control board includes low-standard version files. For example, the first new main control board includes 5G version Files, the first main control board includes 4G version files.

Optionally, after replacing the first main control board with the first new main control board in this embodiment, it further includes at least the following steps, as shown in Figure 2:

S201: The first new main control board downloads the board replacement upgrade identification file and the service configuration file from the second main control board.

It should be understood that the board replacement upgrade identification file on the second main control board can be manually configured by the staff when replacing the first main control board with the first new main control, and the replacement upgrade identification file is used for the first new main control board. The control board sets the first new main control board as the active main control board according to the board replacement upgrade identification file.

In some examples, the first new main control board can only download the service configuration file from the second main control board without downloading the replacement upgrade identification file. The second main control board sends the upgrade identification file to the first new one according to the replacement upgrade identification file on it. The main control board only needs to issue an identification or command to set it as the main control board.

In some examples, the service configuration file includes an integrated communication device network attribute configuration file.

S202: Close the inter-board communication between the first new main control board and other single boards, and set the first new main control board as the active main control board.

It should be understood that the other boards in this embodiment all refer to the second main control board and line card on the communication device, that is, close the connection between the first new main control board and the second main control board and line card. Board-to-board communication.

S203: The first new main control board loads the service configuration file to restore the service configuration information.

Optionally, the service configuration file is loaded on the first new main control board to restore the service configuration information.

Optionally, the first new main control board uses logic hardware The connection method informs the second main control board to reset.

In some examples, after the first new main control board loads the service configuration file and restores all service configuration information, after it notifies the second main control board to reset, it also includes: resetting the second main control board within the first preset time period. Monitor whether the main control board is reset. When it is detected that the second main control board is not reset, a notification message is issued again to inform the second main control board that the reset is required; among them, in practical applications, the first preset time The period can be flexibly set by the developer according to experiment or experience, for example, the first preset time period is set to 15 minutes.

S205: The second main control board is reset as the standby main control board.

Optionally, the second main control board resets after receiving the reset notification. At this time, the second main control board serves as a standby main control board.

Optionally, after the second main control board is reset as the standby main control board in this embodiment, it also includes at least the following steps, as shown in Figure 3:

S301: The first new main control board notifies all line cards to reset.

In some examples, after the second main control board is reset as the standby main control board, it can wait for the second preset time period to ensure that the first new main control board can manage all the line cards mechanically or in hardware. Among them, in practical applications, the second preset time period can be flexibly set by the developer based on experiments or experience, for example, the first preset time period is set to 30 seconds.

S302: All line cards are reset.

It should be understood that all line cards are reset separately when receiving the line card reset notification.

Optionally, in this embodiment, after all the line cards are reset, the method further includes: enabling the inter-board communication between the first main control board and other boards to respond to the version request of the other boards.

It should be noted that for all other line cards, the high-standard version file can be requested from the first new main control board to operate normally, and the communication equipment business returns to normal; for the second main control board, it may be because of the first new main control board. The high-standard version file stored on the control board is not supported and cannot be started, that is, the reset fails. At this time, the second main control board can be upgraded. Among them, the service recovery of communication equipment refers to the original service on the communication equipment. If the communication equipment needs to support new services, such as 5G services, it needs to insert a new line card that supports 5G services; for high and low standard version files, the original communication equipment Some service configurations may be incompatible. To ensure compatibility, in this embodiment, the service can be restored by loading the txt script. If the txt script is not compatible, the first new main control board performs compatibility conversion and converts the txt script into A txt script that can be recognized by high-standard version files.

S102: After the first main control board is successfully upgraded, upgrade the second main control board.

Optionally, upgrading the second main control board in this embodiment includes: replacing the second main control board with a second new main control board.

It should be understood that, since the first new main control board is operating normally at this time, the first new main control board is used as the main main control board, and the second new main control board after replacement is used as the standby main control board; The new main control board includes high-standard version files, and the second main control board includes low-standard version files. For example, the second new main control board includes 5G version files, and the second main control board includes 4G version files.

Optionally, the line card in this embodiment carries a storage medium or does not carry a storage medium. When the line card carries the storage medium, the storage medium may or may not store the version file; when the storage medium stores the version file When filing, include at least the following three methods:

Method 1: Download and run the version file of the first new main control board based on the version file of the first new main control board.

Method 2: Run the version file based on the version file stored in the storage medium of the line card.

Method 3: Compare the version file of the first new main control board with the version file in the line card storage medium. When the version file of the first new main control board is the latest version, download and run the version file of the first new main control board , When the version file in the line card storage medium is the latest version, run the version file.

It is worth noting that the above-listed are only three common methods, which can be flexibly adjusted according to specific application scenarios in actual applications.

The upgrade method provided by the embodiment of the present invention uses the first main control board and the second main control board for centralized management, maintains the normal operation of the second main control board, and upgrades the first main control board. Optionally, After the upgrade of the first main control board is successful, the second main control board is upgraded; it solves the problems of complicated operation of the communication device upgrade in related technologies, long service interruption time in the upgrade process, and low upgrade efficiency. That is to say, the upgrade method provided by the embodiment of the present invention maintains the normal operation of the second main control board when the first main control board is upgraded, and maintains the first successful upgrade when the second main control board is upgraded. For the normal operation of a main control board, the service interruption time during the upgrade process only depends on the start-up time of the line card, not the start-up time of the main control board, the time when the main control board loads the service configuration, and the line card start-up time. It can be seen that the whole The service interruption time is significantly shortened, which greatly improves the efficiency of communication equipment upgrades.

Embodiment two:

On the basis of the first embodiment, the embodiment of the present invention provides a centralized management mode of the version file of the communication device, that is, the software, as shown in Figure 4:

First, it should be noted that in this embodiment, the active main control board is recorded as MSC, the standby main control board is recorded as SSC, and the line card is recorded as NSC.

Optionally, the communication device has two main control boards and multiple line cards. The hardware of the main control board is 1+1 protection, that is, the main main control board MSC and the standby main control board SSC, where the main main control board MSC Both the SSC and the standby main control board have storage media, such as SSD cards; the line card NSC may have no storage media, or storage media, such as fash. When all boards are started, they will request the version file from the main control board MSC, and then run the downloaded version file. Examples are as follows:

If the line card NSC does not have a storage medium, if the version file corresponding to the line card NSC stored on the main main control board MSC is BaseVer21.bin, then the line card NSCboot will directly download the file from the main main control board MSC to the memory In, and then run;

If the line card NSC has a storage medium, but the storage medium does not save the version information, the startup process is the same as that of the board without the storage medium; if there is a saved version file in the storage medium, for example, the version of the version file is BaseVer31.bi n . The running version can be determined according to different usage strategies. For example, the MSC version of the main main control board shall prevail, and the MSC version of the main main control board shall be downloaded first; if the NSC version of the line card shall prevail, the line card shall be run first The version saved by the NSC itself; the version number can also be compared, and the new version of the version number shall prevail. For the centralized version management mode, in this embodiment, a strategy based on the version of the main control board MSC may be adopted to facilitate the user to manage the version information of the communication device.

Example three:

On the basis of the first and second embodiments, the embodiment of the present invention takes a relatively specific upgrade process as an example for description.

As mentioned earlier, when there are new business requirements, the hardware of the main control board needs to be upgraded at the same time that the communication device software also needs to be upgraded. The software upgrade of the communication device can be completed using the version stored on the main control board, as shown in Figure 5. Show:

Step 1: Insert the new main control board into the spare main control slot of the communication device. The original main control board is running version V2.0, and the new main control board is running version V5.0;

It should be understood that the new main control board inserted at this time is used as the backup main control board, and the original main control board is still used as the main main control board.

Step 2: After the new main control board is started, immediately cut off the inter-board communication with the original main control board and line card, and press the main main control board to start.

It should be understood that the new main control board at this time serves as the main main control board.

Step 3: After the new main control board is started and the service configuration is restored, the original main control board is notified to reset, and then all line cards are notified to reset after a period of time; if the original main control board is not supported by V5.0, it will not be able to Start, all line cards support, request V5.0 version from the new main control board again, and run the new V5.0 version.

It should be understood that the new main control board at this time is used as the main main control board, and the original main control board is reset as the standby main control board.

At this point, both the main main control board and line card are running the new V5.0 version to complete the communication equipment software upgrade and the hardware upgrade of the main main control board; the original main main control board can basically make it clear that it cannot meet the new business needs. Therefore, it will also be unplugged and replaced with a new main control board. In addition, the line card may also need to be replaced with a single board to support new business requirements.

Embodiment four:

On the basis of the first to third embodiments, the embodiment of the present invention takes another more specific upgrade process as an example for description.

As mentioned earlier, for communication equipment that needs to support new technologies, such as 4G to 5G or 5G to 6G, both the main control board and the line card may need to be upgraded to new hardware. In order to support traditional services, the line card It may be necessary to retain some of the original old boards, as shown in Figure 6:

S601: Insert a new main control board into the standby main control slot of the communication device, and the main control board boot guides the operating system of the board to start.

For example, suppose that the main control board of the communication device includes the first main control board A1 in the standby main control slot, and the second main control board A2 in the main main control slot. At this time, replace it with the first new main control board B1 The first main control board A1, the first main control board A1boot guide the operating system of the board to start.

S602: The new main control board requests a board replacement to upgrade the identification file and the service configuration file from the original main control board.

Continuing the above example, optionally, suppose that when the staff replaces the first main control board A1 with the first new main control board B1, the second main control board A2 is configured with a board replacement upgrade identification file, including a specific directory and File: /sysdisk0/sscupgrade/upgradecfg.ini file; at the same time, the first new main control board B1 downloads the business configuration file startrun.dat from the second main control board A2.

S603: When the new main control board fails to download the replacement upgrade identification file and the service configuration file, it starts as the standby main control board, and executes S602.

It should be understood that due to the inconsistency with the version file of the original main control board, the board is restarted. After the restart, the version file will be requested from the original main control board, but since the original main control board does not support the new main control board, the new main control board starts If it fails, you need to continue to restart.

Continuing the above example, optionally, when the first new main control board B1 fails to download the board replacement upgrade identification file and the service configuration file from the second main control board A2, repeat S602.

S604: When the new main control board successfully downloads the replacement upgrade identification file and the service configuration file, it starts up as the main main control board, and closes the inter-board communication between the board and other boards.

Continuing the above example, optionally, when the first new main control board B1 successfully downloads the replacement upgrade identification file and the service configuration file from the second main control board A2, shut down the first new main control board B1 and the second communication device Inter-board communication between the main control board A2 and other line cards.

S605: The new main control board converts the downloaded service configuration file into a service configuration file that the board can recognize, and then loads the service configuration file when the software starts.

Continuing the above example, optionally, the first new main control board B1 converts the downloaded startrun.dat file into a business configuration file that can be recognized by the board, and then loads the business configuration file startrun.dat when the software starts.

S606: After loading the service configuration file of the new main control board, notify the original main control board to reset.

Continuing the above example, optionally, after the service configuration file of the first new main control board B1 is loaded, the second main control board A2 is notified to reset by way of logical hardware connection.

Optionally, monitor whether the second main control board A2 is reset within the first preset time period, and when it is detected that the second main control board A2 has not been reset, a notification message is issued again to inform the second main control The board A2 needs to be reset, and the first preset time period can be 15 minutes.

S607: After the original main control board is reset, all the line cards on the electromechanical or hardware management of the new main control board are notified to reset all the line cards.

Continuing the above example, optionally, all the line cards on the electromechanical or hardware management of the first new main control board B1 are notified to reset all the line cards.

Optionally, after the second main control board A2 is reset, it can wait for a second preset time period to ensure that the first new main control board B1 can manage all the line cards mechanically or in hardware, where the second preset time The segment can take 15 seconds.

S608: The new main control board opens the board-to-board communication between this board and other boards, and responds to the version requests of other boards. All boards that can request the version file will run the new version.

It should be understood that, in order to ensure the smooth upgrade of communication equipment, the high-standard version files contained in the new main control board will generally contain all the new software version files required by the original line card.

Continuing the above example, optionally, the first new main control board B1 opens its inter-board communication with the second main control board A2 and all line cards, and all line cards run the high-standard version files on the first new main control board B1 .

S609: Insert another new main control board into the main main control slot of the communication device.

Continuing the above example, optionally, replace the second main control board A2 with the second new main control board B2.

So far, the software and hardware upgrades of all the boards on the communication equipment have been completed. The original service interruption time during the upgrade process depends on the time when the line card is started. If new services need to be supported, reconfiguration is required.
