Embodiment Construction

[0045] In the clock, operation and maintenance monitoring board and the method for master / standby switching of the present invention, the switched objects are treated differently, wherein the switched objects are divided into the following two categories according to whether the switching needs the judgment and control of the main control software:

[0046] The first type of switching object is information that must be switched by software, such as high-level business information, control information, and operation and maintenance information;

[0047] The second type of switching objects is information that can be switched without software participation, such as system clock information and system synchronization information.

[0048] At the same time, in the clock, operation and maintenance monitoring board and the method for master / standby switching thereof of the present invention, after the main first clock and the operation and maintenance monitoring board fail, the stand...

Abstract

The invention discloses a clock and an operation-maintenance monitoring plate and method for switching from the primary device to the backup device. The clock and operation-maintenance monitoring plate is applied to the communication system, comprising a first switching object processing module and a second switching object processing module and a main control module, further: a second switching object output control module for stopping the second switching object processing module or starting the output of second switching object processing module by the hardware; the main control module is further applied to obtaining the first switching object distributed to the first switching object output control module and controlling the first switching object processing module to start to processwhen the second switching object output control module controls the output of the second switching object. The invention accelerates initializing process of the whole base station. When the main-board malfunctions, the switching time may be micron second, not causing jumping of system synchronizing information.

Description

technical field [0001] The invention relates to the switching of main and standby devices in a communication system, in particular to a clock and an operation and maintenance monitoring board and a method for switching between main and standby devices. Background technique [0002] Stability and reliability are essential characteristics of communication equipment. In order to enhance the stability and reliability of the system, it is generally necessary to perform backup operations on key parts of the communication system, which are divided into primary equipment and standby equipment. When the system is working normally, the primary device is enabled; when the primary device fails, the system must quickly switch to the backup device, so that the system can work continuously, and at the same time, the user should not feel the inconvenience caused by the switching of the device. [0003] According to whether the running state and running data are synchronized between the stan...
