Problems solved by technology

However, the main control board notifies the failed active board and the standby board to perform active-standby switchover in a serial manner, so that the failed active board and the standby board do not achieve switching synchronization. , when the main board is downgraded to the standby state, but the original standby board is not switched over, the newly received services will be lost

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0042] Different from the prior art, the embodiment of the present invention is that: the main control board sends the switching time information determined by it to the main board and the standby board; The signal is a reference source, and it is judged whether the time information carried in the designated global frame timing signal is the same as the switching time information, and if so, switching processing is performed.

[0043] As the system synchronization reference source, the global frame timing signal can provide system synchronization frame number and absolute time information, and is applicable to base stations of all wireless systems. In the embodiment of the present invention, the specified global frame timing signal is used as a referenc...

Abstract

The invention discloses a method for single board main / standby switch, which comprises: a master control board sends a switch time information determined thereby to a main single board and a standby single board; the main single board and the standby single board utilize the received designated global frame timing signal as reference source to judge whether the time information contained in the designated global frame timing signal is the same as the switch information, if it is, performing the switch operation. The invention also discloses a system for single board main / standby switch and a single board. The method can ensure the single board main / standby switch synchronous and reduce the service loss during the single board main / standby switch process, even no loss.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for main-standby switchover of a single board and a single board. Background technique [0002] In communication technology, for the reliability of the system, redundant backup design is generally carried out on the key components of the system, so that it can support the main backup work, and ensure that when the main component fails, it can be smoothly switched to the standby component, so as to reduce the The impact of component failures on the system. [0003] The board in the active state is called the active board; the board in the standby state is called the standby board. The active single board and the standby single board are mutually backed up, so that when the active single board fails, it can be switched to the standby single board. The mutual switching between the active board and the standby board is called active / standby switchover. [0004] At pr...
