Problems solved by technology

[0004] Using the above-mentioned active-standby switchover method to upgrade, there will be the following risks: If the process data area structure of the business process has changed in the new version compared with the original version during the above process, if the standby board still backs up the main board during the upgrade process Synchronized process data area data, the data pointer may point to the wrong data address, which will lead to process data area backup error or even system crash

Embodiment

[0054] This embodiment takes the calling service as an example.

[0055] image 3 It is a schematic diagram of a smooth upgrade method for communication equipment according to an embodiment of the present invention, as shown in image 3 As shown, this embodiment includes four veneers, namely: veneer a, veneer a', veneer b, and veneer b'; wherein, veneer a' is the backup board of veneer a, and veneer b' is the standby board of board b, and board a and board b are in active state. Process data area messages are exchanged between board a and board a', board b and board b'. In the following, the master / standby upgrade process between board a and board a' is taken as an example for illustration.

[0056] Board a' loads a new version. After power-on, each business process of single board a' enters the standby state, and the global variable of the data area version consistency of each business process is set to "Unknown". After board a is powered on, when each service process ent...

Abstract

The invention discloses a smooth upgrading method of communication equipment, which comprises the following steps: a business process needing synchronization on a standby board loaded with a new edition transmits a process data area backup request to a business process which corresponds to a main board, and the process data area backup request carries a process data area edition number; after theprocess data area backup request is received, the main board judges whether the process data area edition number of the self business process conforms to the process data area edition number of the business process on the standby board, if so, the main board transmits a backup response message to the standby board, or else, the main board transmits a backup finishing message to the standby board;and after the data backup of all process data areas is finished, the main board and the standby board are converted. The invention also discloses a smooth upgrading system of communication equipment,which comprises the standby board and the main board, wherein the standby board comprises a standby board upgrading unit and a data standby unit, and the main board comprises a main board judging unit. The method and the system can realize the smooth upgrading of the communication equipment.

Description

technical field [0001] The present invention relates to the upgrade technology in the field of communication, in particular to a smooth upgrade method and system for communication equipment. Background technique [0002] In the system security design, the 1+1 backup feature is designed for many single boards. When upgrading this type of board, the master / standby mechanism of the board can be used to avoid service interruption. [0003] figure 1 It is a schematic diagram of upgrading the communication equipment in the prior art through active-standby switching mode, figure 1 Filling in with a slash in the middle indicates that it is in the active state. The board in the active state is called the main board, and the board in the standby state is called the standby board. Such as figure 1 As shown, first load the new version to the standby board, that is, figure 1 In the right board, the right board initiates a backup request after restarting to back up the main board, th...
