Description
Technical field
The present invention relates to the communications field, relate in particular to the method for a kind of OMU equipment and the active and standby two-shipper of realization OMU.
Background technology
Network element (such as, mobile switching centre, base station controller, radio network controller etc.) generally comprise an Operation and Maintenance Unit (OMU, Option Management Unit) and the polylith veneer, the general carrier class PC server of the general employing of OMU, can adopt general operating systems such as Linux and Windows Sever, be used for network element is carried out oam, veneer then provides the service processing function of network element.Along with to the improving constantly of OMU reliability requirement, introduce OMU dual-host backup mechanism, the mode that the active and standby two-shipper of a kind of OMU is realized is: increase hardware and connect between OMU, such as increasing serial ports line, direct-connected network interface card between the OMU.After OMU starts,, the other side is sent message, and accepted the message that the other side sends by serial ports or direct-connected network interface card.If receive the other side's message, then show two-shipper all in work, two-shipper carries out that active and standby negotiation is laggard goes into active and standby operating state; If can not receive the other side's message in a period of time, then think the other side's fault oneself to enter the main state of using.The shortcoming of this mode be need be on OMU the configure hardware support equipment, such as, serial ports or straight line network interface card.Thus, introduce the mode that the active and standby two-shipper of another kind of OMU is realized, this mode disposes the information of the other side OMU when OMU Software is installed, as the other side's IP address, computer name etc.After OMU starts, obtain the other side's IP address or computer name, send message, and receive the message that the other side sends to the other side.Equally, if receive the other side's message, then show two-shipper all in work, two-shipper carries out that active and standby negotiation shape is laggard goes into active and standby operating state; If can not receive the other side's message in a period of time, then think the other side's fault oneself to enter the main state of using.This scheme is compared with the first string does not need the configure hardware support equipment, but this scheme still need be in OMU internal configurations the other side information, if the information configuration mistake, then the OMU two-shipper can't operate as normal; If information such as the IP address of an OMU or computer name are revised, need on another OMU, revise configuration again, operate cumbersome.
Summary of the invention
In order to solve the problems of the technologies described above, embodiment of the invention technical problem to be solved is, the method for a kind of OMU equipment and the active and standby two-shipper of realization OMU is provided.Can avoid the OMU two-shipper to use hardware supports equipment and configuration the other side information to assist and realize the active and standby two-shipper of OMU.
Given this, the embodiment of the invention provides a kind of method that realizes the active and standby two-shipper of Operation and Maintenance Unit OMU, comprising:
The one OMU comprises configuration information and the state information of a described OMU in the interior network segment broadcast of network element in the described message;
A described OMU intercepts the broadcast in the interior network segment of described network element;
When listening to the broadcast of the configuration information that includes the 2nd OMU and state information, a described OMU carries out active and standby negotiation according to configuration information and the state information of self configuration information and state information and described the 2nd OMU with described the 2nd OMU;
A described OMU is combined into the active and standby two-shipper of OMU according to described active and standby negotiation result and described the 2nd OMU.
Accordingly, the embodiment of the invention also provides a kind of Operation and Maintenance Unit OMU equipment, comprising:
