Embodiment one
Fig. 2 is referred to, the embodiment of the present invention provides a kind of method for transmitting OAM message, and the main flow of methods described is such as
Under：
Step 201：MEP in Virtual Home MEP determines whether the MEP is host node.Wherein, when it is determined that the MEP
During for host node, that is, result is determined when being, to perform step 202, when it is determined that the MEP is not host node, that is, determine result
For it is no when, perform step 203.
Fig. 3 is referred to, is the transmission channel schematic diagram of OAM message.2 and 3 in Fig. 3 represent a MEP respectively, the two
It is so that the Virtual Home MEP includes two MEP as an example that MEP, which is constituted in the Virtual Home MEP, i.e. Fig. 3,.But it is of the invention real
Apply the Virtual Home MEP in example to be not limited to only be made up of two MEP, it can include multiple MEP.Dotted line frame in Fig. 3
It is inside 2 and 3, represents the 2 and 3 composition Virtual Home MEP.From figure 3, it can be seen that having connecting path, 2 Hes between 2 and 3
3 can be communicated by the connecting path.
1 in Fig. 3 represents in a MEP, the embodiment of the present invention for convenience, can be referred to as receiving terminal by 1.1 is not
Belong to the Virtual Home MEP.
For example, 1 can be connected with first network side apparatus, 2 can be connected with 3 with the second network side equipment, such as institute
It can be base station to state first network side apparatus, such as described second network side equipment can be RNC（Radio Network
Controller, radio network controller）, it is not shown in figure 3.
Specifically, in the embodiment of the present invention, MEP2 and MEP3 shown in Fig. 3 can be two nodes in network, can
To be that MEP2 and MEP3 sets identical property parameters first, thus institute is set to equivalent to by the MEP2 and the MEP3
State Virtual Home MEP.For other network elements in network, the Virtual Home MEP is exactly a MEP, then, no matter described
How many MEP Virtual Home MEP includes, and it is externally just rendered as a MEP.A MEP externally is rendered as, mainly
Refer to, for receiving terminal, can only see a Virtual Home MEP.
In the embodiment of the present invention, if only including two MEP in the Virtual Home MEP, the two Virtual Homes MEP
It is referred to as virtual MEP dual homeds node.
In the embodiment of the present invention, MEP property parameters can include but is not limited to MEG ID（Maintenance Entity body
Part certification）、MEP ID（The end points authentication of Maintenance Entity）、MAC Address （Media Access Control
Address, media access control address）, etc..
Preferably, in the embodiment of the present invention, before the MEP in Virtual Home MEP determines whether the MEP is host node
Or afterwards, the MEP may also receive from the second OAM message of the receiving terminal.
If in determining the MEP receives second OAM message before whether being host node, then the MEP can
To continue to determine whether the MEP is host node.
If in determining whether the MEP is to receive second OAM message after host node, then the MEP because
To determine whether the MEP is host node before, it need not can determine again, or, the MEP can also determine described again
Whether MEP is host node.
Further, in the embodiment of the present invention, determine whether the MEP is host node and receives described the in the MEP
After two OAM messages, if the MEP determines that the MEP is host node, directly second OAM message can be carried out
Processing.
Further, in the embodiment of the present invention, determine whether the MEP is host node and receives described the in the MEP
After two OAM messages, if the MEP determines that the MEP is not host node, the MEP can send out second OAM message
The host node in the Virtual Home MEP is given, second OAM message is handled by host node.It is described in the embodiment of the present invention
Host node in Virtual Home MEP and from having connecting path between node, host node and can pass through the connection from node
Path is communicated.
Step 202：The MEP is generated when it is determined that the MEP is host node and is sent the first OAM message to receiving terminal.
In the embodiment of the present invention, if the MEP determines that the MEP is host node, the MEP can be generated and to institute
State receiving terminal and send first OAM message.
In the embodiment of the present invention, the host node in the Virtual Home MEP can generate first OAM message, and can
To send first OAM message to the receiving terminal, first OAM message is handled by the receiving terminal.Then, institute
Stating in Virtual Home MEP MEP can determine whether the MEP is host node first, if it is determined that be saved based on the MEP
Point, then the MEP can generate first OAM message.
Step 203：The MEP forbids generation first OAM message when it is determined that the MEP is not host node；Its
In, Virtual Home MEP includes at least two MEP, and each MEP property parameters are identical.
In the embodiment of the present invention, if the MEP determines that the MEP is not host node, forbid generation the first OAM
Message.That is, in the embodiment of the present invention, in the Virtual Home MEP, only host node can generate OAM message, and be connect to described
Receiving end sends the OAM message of generation, and OAM message will not be then generated from node, and OAM reports will not be more sent to the receiving terminal
Text, so as to ensure that the receiving terminal can only receive a OAM message, effectively prevent the receiving terminal and the feelings of abnormality alarming occurs
Condition.
In the embodiment of the present invention, the receiving terminal can generate second OAM message, it is possible to the Virtual Home
The MEP that MEP is sent in second OAM message, the Virtual Home MEP is received after second OAM message, can be with
Whether be host node, if it is determined that determining that the MEP is host node, then the MEP can be directly to institute if first determining whether the MEP
State the second OAM message to be handled, if it is determined that determining that the MEP is not host node, then the MEP can be by described second
OAM message is sent to host node, and second OAM message is handled by host node.
Can there is no sequencing relation in the embodiment of the present invention between both approaches to be protected.
Further, in one embodiment of the invention, one and only one host node in the Virtual Home MEP.The side
Method can also include：When meeting preparatory condition, masterslave switchover occurs for the MEP and another MEP.
If the MEP is host node, when meeting the preparatory condition, the MEP can complete to lead with one from node
It is standby to switch.
If the MEP is from node, when meeting the preparatory condition, the MEP can complete to lead with a host node
It is standby to switch.
Preferably, if it is determined that the MEP is not host node, then the MEP can in real time, regularly or when being triggered be monitored
Whether host node is normal, if the MEP determines that host node is abnormal, the MEP can be set to host node by the MEP.
Now, the preparatory condition is：The MEP determines that host node is abnormal.
Preferably, if it is determined that the MEP is not host node, then the MEP can in real time, regularly or when being triggered be monitored
Whether the connecting path between host node is normal, if the MEP determines that the connecting path is abnormal, and the MEP can be with
The MEP is set to host node.
Now, the preparatory condition is：The MEP determines that the connecting path is abnormal.
Preferably, if it is determined that the MEP is host node, then the MEP can in real time, regularly or when being triggered to described
MEP is monitored, if monitoring determines that the MEP is abnormal, and the MEP can be to one in the Virtual Home MEP from section
Point sends information, and this is set into host node from node.
Now, the preparatory condition is：The MEP determines that the MEP is abnormal.
Preferably, the Virtual Home MEP can receive the switching command for realizing masterslave switchover, then receiving
State after switching command, the host node and one in the Virtual Home MEP can complete masterslave switchover from node.
Now, the preparatory condition is：The MEP receives the switching command for realizing masterslave switchover.
