WORD frmno; The numbering of // veneer place frame
WORD slotno; The numbering of groove position, // veneer place
}
The basic procedure of hard coded mode is as follows:
The if NE type is MSC then
{
struct?MSCboardquery*cmdfrm；
Be cmdfrm storage allocation space;
cmdfrm.cmdno＝52；
The frame of the required Query Board of cmdfrm.frmno=number;
The slot number of the required Query Board of cmdfrm.slotno=;
By communication link cmdfrm is mail to MSC with network element MSC;
}
else
The if NE type is BSC then
{
struct?BSCboardquery*cmdfrm；
Be cmdfrm storage allocation space;
cmdfrm.cmdno＝5；
The frame of the required Query Board of cmdfrm.frmno=number;
The slot number of the required Query Board of cmdfrm.slotno=;
By communication link cmdfrm is mail to BSC with network element BSC;
}

Starting the inquiry of a MSC (mobile switching centre) network element device single board state with network management system below is example, and the concrete implementation step of the inventive method is described:
At first, the each several part protocol definition is as follows:
The network management system querying command:
struct?NM_BoardQuery
{
int?CmdNo；//cmdno＝20
BYTEfrmno; The numbering of // veneer place frame
BYTE slotno; The numbering of groove position, // veneer place
}
MSC single board state query interface:
Struct?MSCboardquery
{
BYTE cmdno; // command code, the command code of single board state inquiry is 52;
BYTE frmno; The numbering of // veneer place frame
BYTE slotno; The numbering of groove position, // veneer place
}
The NE type of MSC is defined as 2.
According to agreement as defined above, above-mentioned table one, table two and table three concrete configuration are as follows.
It is as follows to obtain the configuration of CmdMap form from structNM_BoardQuery:
| NMCmdNo | NEType | NECmdNo |
| 20 | 2 | 52 |
The MSC NE type is 2, and the command code that can obtain its Query Board state from Struct MSCboardquery is 52, and three parameters are arranged, and total length is 3 bytes, and it is as follows then to obtain the configuration of NECmdInfo form:
| NEType | NECmdNo | ParamCount | FrameLength | CmdDescription |
| 2 | 52 | 3 | 3 | Query?board?state |
The MSC NE type is 2, the 2nd parameter f rmno of Struct MSCboardquery is corresponding with the 2nd parameter among the structNM_BoardQuery, the 3rd parameter s lotno of struct MSCboardquery is corresponding with the 3rd parameter among the struct NM_BoardQuery, and it is as follows then to obtain the configuration of NEParamInfo form:
| NEType | NECmdNo | ParamNo | ParamType | ParamLen | PeerParamNo | PeerParamType | PeerParamLen | ParamDefaultValue |
| 2 | 52 | 1 | BYTE | 1 | NULL | NULL | NULL | 52 |
| 2 | 52 | 2 | BYTE | 1 | 2 | BYTE | 1 | NULL |
| 2 | 52 | 3 | BYTE | 1 | 3 | BYTE | 1 | NULL |
When network management system is sent a MSC single board state querying command, when needing the state of veneer on inquiry MSC the 3rd frame the 5th groove position, order as follows:
struct?NM_BoardQuery?nmcmd；
nmcmd.CmdNo＝20；
nmcmd.FrmNo＝3；
nmcmd.SlotNo＝5；
The network element adapter inquires the corresponding net element command code according to CmdNo and NE type from the CmdMap table be 52, from the NECmdInfo form, inquire this order according to NE type and network element commands sign indicating number then 3 parameters are arranged, from the NEParamInfo form, inquire about type, the length of each parameter then one by one, corresponding network management command parameter type, length, carry out the assignment conversion one by one according to the transformational relation between the corresponding types then, constitute and mail to the protocol frame of network element device, and be sent to network element device.Detailed process is as follows:
After the network element adapter was received the nmcmd protocol frame, the cmdno that obtains wherein was 20, showed as condition query CmdMap with NMCmdNo=20 and NEType=2, drew the command code NECmdNo=52 of this network element Query Board status command;
With NECmdNo=52 and NEType=2 is condition query NECmdInfo table, draws this command parameter number ParamCount=3, frame length FrameLength=3;
The memory headroom that distributes 3 bytes for the single board state protocol frame that will mail to MSC;
To be condition inquire the 1st parameter type from the NEParamInfo table with NECmdNo=52 and NEType=2 is that BYTE, length are 1; Corresponding webmaster command parameter be numbered NULL, type is that NULL, length are NULL, the default value of this parameter is 52.Because this parameter length is 1, get the 1st byte in the 3 byte of memory spaces of distributing previously, assignment 52 is finished the processing of the 1st parameter;
To be condition inquire the 2nd parameter type from the NEParamInfo table with NECmdNo=52 and NEType=2 is that BYTE, length are 1; Corresponding webmaster command parameter be numbered 2, type is that BYTE, length are 1, the default value of this parameter is NULL.Because this parameter length is 1, and previous parameter has taken 1 byte, then gets the 2nd byte in the 3 byte of memory spaces of distributing previously, because the 2nd parameter (its value is 3) in its corresponding webmaster order, so assignment 3 is finished the processing of the 2nd parameter;
To be condition inquire the 3rd parameter type from the NEParamInfo table with NECmdNo=52 and NEType=2 is that BYTE, length are 1; Corresponding webmaster command parameter be numbered 3, type is that BYTE, length are 1, the default value of this parameter is NULL.Because this parameter length is 1, and preceding two parameters have taken 2 bytes, then get the 3rd byte in the 3 byte of memory spaces of distributing previously, because the 3rd parameter (its value is 5) in its corresponding webmaster order, so assignment 5 is finished the processing of the 3rd parameter;
The content of 3 bytes after assignment handled mails to the MSC network element device as the content in the communication frame by communication management module, has realized that with the network management system protocol conversion be the network element device interface protocol.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
