＆ Maintenance Center, operation maintenance center) and NMS (Network Management System, NMS
System) cooperate and formulated north orientation Corba interface specifications.Corresponding data are offered NMS by OMC according to this set specification.
In traditional north orientation Corba interfaces, NMS, which has the initiative, manages status, sends corresponding order by NMS, then
Response is provided by OMC or corresponding announcement information is sent.Due to north orientation Corba interfaces connecing for OMC and NMS two systems
Mouthful, thus it is related to corresponding link detection mechanism.In this regard, north orientation Corba interface specifications define the reference Point C S of correlation
Corresponding operation is defined in IRP, this reference point and is notified, by the reference point, NMS can require that OMC sends one immediately
Heartbeat message gives the NMS, NMS to confirm OMC by periodically receiving heartbeat message with some cycles timing transmission heartbeat message
Online and response condition.
But, in the north orientation Corba interfaces that current mobile communications network is used, OMC and NMS link detecting are only deposited
Report that such a link detection mechanism has following defect to NMS Link State in OMC：
1st, the waste of OMC resources and unnecessary consumption：According to the actual usage scenario of system, OMC is normal application on site, and
NMS is not normal application on site, that is to say, that NMS can be closed often or port switching, but can not be obtained in OMC sides
NMS virtual condition, therefore dynamically can not determine whether business information needs transmission according to NMS actual conditions, can only
Continue the uninterrupted transmission of blindness, and in actual applications, NMS change is more frequent, and many NMS are equal when starting every time
It can be ordered with new port, in order to keep the stability and compatibility ordered in the past, OMC must be sent out to all ports
Message is sent, thus causes OMC in the case of NMS closings or port switching, does not stop paying out still and sent both to some idle NMS
Fixed business information, so as to waste OMC resource, has also dragged slowly system whole efficiency, and EMS enters row information to NMS
It is a large amount of to repeat to send, NMS burden is added, the accumulation of NMS ends message is easily caused, or even trigger resource to overflow, keep a large amount of
Connection and information send and code certainly will be made more complicated, add exploitation maintenance cost；
2nd, due to not knowing about NMS online situation, it can not be handled in time when there are abnormal conditions, it is impossible to which judgement is OMC
Failure, which causes information can not transmit still NMS closings (or abnormal), to be caused not collect data, in actual use
Verification of data, positioning problems and responsibility judgment bring very big puzzlement.Due to there was only unidirectional heartbeat message, therefore only
One side can carry out heartbeat message detection, if the report of NMS ends can not receive heartbeat message, heartbeat message has then been thought in EMS ends
Send, cause NMS not receive the problem of be network or Corba communications itself so that responsibility can not be defined.
Therefore, existing unidirectional heartbeat message link detection mechanism can not meet the need of existing network management system mating interface
Will.
