Meanwhile, under the same technical background, such as the 4G age, the software and hardware of the equipment are continuously updated. During the same technical period, the upgrade of the device may be mainly the upgrade of the software, and the current classification of the software upgrade from the impact on the service is mainly in two ways, namely interrupting the service upgrade and not interrupting the service upgrade. The interrupt service upgrade is mainly realized by protection switching or CPU soft reset under the condition that the front and back compatibility of software is ensured while the incompatible situation of the two versions before and after the upgrade is not solved. However, if a different technology age is processed, in addition to possible incompatibility of software when upgrading from a 4G version to a 5G version, incompatibility of device hardware may also occur, for example, in the 5G age, in order to guarantee a higher downloading speed and lower time delay, a high-precision clock function needs to be supported, which necessarily results in hardware updating.

Then, when the software and hardware of the device single board are not compatible, how to implement rapid device upgrade is a key technical problem that all device manufacturers must face. The general upgrading method is that the service configuration file of the original equipment is imported to a new main control board, then the old main control board is replaced by the new main control board, and then the whole machine is restarted to realize the upgrading. The operation of the mode is complex, wherein the service interruption time comprises a new main control board starting time, a new main control board service restoration configuration time, a line card starting time and the like, when the service configuration files are more, the service restoration time of the new main control board is longer, and the service interruption time in the whole upgrading process is longer.
Therefore, in the prior art, the operation of upgrading the communication equipment is complex, and the service interruption time and the upgrading efficiency of the upgrading process are long.

Embodiment two:
Based on the first embodiment, the embodiment of the present invention provides a centralized management manner for version files, i.e. software, of a communication device, please refer to fig. 4:
First, in this embodiment, the main control board is denoted as MSC, the standby main control board is denoted as SSC, and the line card is denoted as NSC.
Optionally, the communication device has two main control boards and multiple line cards, and the main control board is protected by 1+1 on hardware, that is, the main control board MSC and the standby main control board SSC, where the main control board MSC and the standby main control board SSC both have storage media, such as SSD cards, and the line cards NSC may have no storage media, or may have storage media, such as flash. When all single boards are started, the version files are requested to the MSC of the main control board, and then the downloaded version files are operated. 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 control board MSC is basever21.Bin, the line card NSCboot directly downloads the file from the main control board MSC to the memory after being started, and then operates;
if the line card NSC has a storage medium, but version information is not stored in the storage medium, the starting flow is the same as that of a single board without the storage medium, and if the storage medium has a version file stored in the storage medium, for example, the version of the version file is BaseVer31.Bin. The running version can be determined according to different use strategies, if the version of the main control board MSC is used as the standard, the version of the main control board MSC is downloaded preferentially, if the version of the line card NSC is used as the standard, the version stored by the line card NSC can be run preferentially, and the version number can be compared, and if the version number is used as the standard, the new version of the version number can be used as the standard. For the centralized version management mode, the embodiment can adopt a strategy based on the version of the MSC of the main control board, so as to facilitate the user to manage the version information of the communication equipment.
Embodiment III:
the embodiment of the invention is described by taking a more specific upgrading process as an example on the basis of the first embodiment and the second embodiment.
As described above, when there is a new service requirement, the main control board hardware is upgraded while the communication device software also needs to be upgraded, and the communication device software upgrade can be completed by using the version stored on the main control board, see fig. 5:
Inserting a new main control board into a standby main control slot of the communication equipment, wherein the version V2.0 operates on the original main control board, and the version V5.0 operates on the new main control board;
It should be understood that the new master control board inserted at this time is used as a standby master control board, and the original master control board is still used as a master control board.
And step two, immediately cutting off the communication between the new main control board and the boards of the original main control board and the line card after the new main control board is started, and starting according to the main control board.
It should be understood that the new master control board at this time serves as the master control board.
And thirdly, after the new main control board is started until the service configuration is restored, notifying the original main control board to reset, and notifying all line cards to reset after a period of time, wherein if the original main control board is not supported by the V5.0 version, the original main control board cannot be started all the time, all the line cards support, and the V5.0 version is requested from the new main control board again to operate the new V5.0 version.
It should be understood that the new main control board is used as the main control board at this time, and the original main control board is used as the standby main control board after being reset.
The primary main control board can basically definitely not meet new service requirements, so that the primary main control board can be pulled out and replaced by a new main control board, and in addition, the line card can also need to be replaced by a single board to support the new service requirements.
Embodiment four:
the embodiments of the present invention will be described with reference to another specific upgrading process based on the first to third embodiments.
As described above, for the communication device to support new technologies, such as 4G upgrade to 5G, or 5G upgrade to 6G, both the main control board and the line card may need to be upgraded to new hardware, and the line card may need to reserve part of the original old board in order to support the traditional service, see fig. 6:

And S603, when the new main control board fails to download the board changing upgrading identification file and the service configuration file, the new main control board is started as a standby main control board, and S602 is executed.
It should be understood that, due to the inconsistency with the version file of the original master control board, the single board restarts, and requests the version file from the original master control board after restarting, but since the original master control board does not support the new master control board, the new master control board fails to start, and then the restarting is continued.
In the above example, further, when the first new main control board B1 fails to download the board change upgrade identification file and the service configuration file from the second main control board A2, S602 is repeatedly executed.
S604, when the new main control board downloads the board-changing upgrading identification file and the service configuration file successfully, the new main control board is used as a main control board to start, and the board-to-board communication between the main control board and other single boards is closed.
In the above example, further, when the first new main control board B1 downloads the board change upgrade identification file and the service configuration file from the second main control board A2 successfully, the board communication between the first new main control board B1 and the second main control board A2 and other line cards of the communication device is closed.
S605, the new main control board converts the downloaded service configuration file into a service configuration file which can be identified by the board, and then the service configuration file is loaded when the software is started.
In the above example, further, the first new main control board B1 converts the downloaded startrun. Dat file into a service configuration file that can be identified by the board, and then loads the service configuration file startrun. Dat when the software is started.
S606, after the new main control board service configuration file is loaded, the original main control board is notified to reset.
The above example is received, and further, after the loading of the service configuration file of the first new main control board B1 is completed, the second main control board A2 is notified to reset in a mode of connecting logic hardware.
Optionally, whether the second main control board A2 is reset is monitored in a first preset time period, and when the second main control board A2 is monitored to be not reset, a notification message is issued again to inform the second main control board A2 that the second main control board A2 needs to be reset, wherein the first preset time period can take 15 minutes.
S607, after the original main control board is reset, all the line cards on the new main control board are managed mechanically and electrically or on hardware, and all the line cards are notified to reset.
In the above example, further, the first new main control board B1 manages all the line cards on the machine or hardware, and notifies all the line cards to reset.
Optionally, after the second main control board A2 is reset, a second preset period of time may be waited to ensure that all the line cards on the first new main control board B1 can be managed mechanically or electrically or in hardware, where the second preset period of time may take 15 seconds.
And S608, the new main control board opens the board-to-board communication between the board and other boards, responds to the version requests of the other boards, and all boards capable of requesting the version file can run new versions.
It should be understood that, in order to ensure smooth upgrade of the communication device, the new main control board will typically include a high-format version file that includes new software version files required by all the original line cards.
In the above example, further, 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 format version file on the first new main control board B1.
S609, another new main control board is inserted into the main control slot of the communication equipment.
The above example is received, and further, the second main control board A2 is replaced by the second new main control board B2.
Thus, the software and hardware upgrading of all single boards on the communication equipment is completed, the time of the original service interruption in the upgrading process depends on the starting time of the line card, and if a new service needs to be supported, reconfiguration is needed.

It should be noted that, for all other line cards, the service of the communication device can be recovered to normal operation after the line cards request from the first new main control board to the high-format version file, and for the second main control board, the second main control board may not be started, i.e. the reset fails, because the high-format version file stored on the first new main control board is not supported, and at this time, the second main control board can be upgraded. The service recovery of the communication device refers to an original service on the communication device, if the communication device needs to support a new service, such as a 5G service, a new line card supporting the 5G service needs to be inserted, and for a high-low format version file, the original service configuration of the communication device may not be compatible, in order to ensure compatibility, a txt script loading mode may be used to recover the service, and if the txt script mode is also not compatible, the first new main control board performs compatibility conversion, and converts the txt script into a txt script that can be identified by the high-format version file.
Optionally, in this embodiment, upgrading the second main control board includes replacing the second main control board with a second new main control board.
It should be understood that, because the first new main control board is normally operated at this time, the first new main control board is used as a main control board, and the replaced second new main control board is used as a standby main control board, where the second new main control board includes a high-format version file, the second main control board includes a low-format version file, for example, the second new main control board includes a 5G version file, and the second main control board includes a 4G version file.
Optionally, the line card in the embodiment carries a storage medium or does not carry a storage medium, wherein when the line card carries the storage medium, a version file or a version file which can not be stored may be stored in the storage medium, and when the version file is stored in the storage medium, at least three modes are included:
the first mode is to 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.
And secondly, operating the version file by taking the version file stored in the line card storage medium as the reference.
And comparing the version file of the first new main control board with the version file in the line card storage medium, downloading and operating the version file of the first new main control board when the version file of the first new main control board is the latest version, and operating the version file when the version file in the line card storage medium is the latest version.
