For making the object, technical solutions and advantages of the present invention express clearlyer, below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
In embodiments of the present invention, based on SIP signaling monitoring, not only when server and another server are mutual for the first time, carry out, and all carry out when mutual and mutual for the third time for the second time at server and another server, thereby improved the success rate of monitoring.In addition, when the file of preserving two parts of servers and sending to another server, the file that can utilize the file verification of again preserving to preserve first, the correctness of the preservation file further improving.
Referring to accompanying drawing 2, be that the embodiment of the present invention improves the schematic flow sheet of the method for monitoring success rate based on SIP signaling, specifically comprise the following steps:
Step 201, catch the sign in the first message.
Server sends the message for the first time with sign to another server, at server mappings port, monitors, and the sign in catching message for the first time performs step 202; Otherwise execution step 203.Between server and another server, adopt standard Session Initiation Protocol.
Sign is different according to its title of different message, but the effect of sign is mainly used for labeled message.Therefore the present invention does not limit the concrete title of sign.In addition, the sign of how to catch in message is prior art, does not repeat them here.
Step 202, start and prepare to preserve file.
Captured the sign in message for the first time, started and prepare to preserve file, for further preserving file at server during to another server Transmit message, prepared.
Start and prepare to preserve file, and not meaning that necessarily and can be saved in file.File is preserved in impact many factors, in order to increase the success rate of preserving file, adopts in the present invention between monitoring service device the repeatedly technical scheme of information interaction.
Step 203, catch the sign in message for the second time.
Another server sends the message for the second time with sign to server, and same monitors at server mappings port, and the sign in catching message for the second time performs step 204; Otherwise, execution step 205.
Sign in this step is identical with the sign in step 201.The repeatedly information interaction that can make full use of between server and another server is caught sign, and then monitoring obtains the file transmitting between server and another server.Than only utilizing between server and another server for the first time information interaction to catch sign, obtain file, the success rate that above-mentioned technical method obtains file improves greatly.
Step 204, start and prepare to preserve file.
Caught the sign in message for the second time, started and prepare to preserve file, for further preserving file at server during to another server Transmit message, prepared.
Step 205, catch the sign in message for the third time.
Utilize server in sip message to send the message for the third time with sign to another server, same monitors at server mappings port, and the sign in catching message for the third time performs step 206; Otherwise, finish.
All do not capture the probability identifying in message three times very little, once not capturing the probability identifying in message is 1%, so three all not capture the probability identifying in message be 1%*1%*1%=0.000001.
Step 206, start and prepare to preserve recording.
Caught the sign in message for the third time, started and prepare to preserve file, for further preserving file at server during to another server Transmit message, prepared.
Two parts of files have been preserved in step 207, judgement at least.
Server and another server carry out tertiary information mutual after, server is to another server Transmit message.At server mappings port, monitor, and then obtain the file that server sends to another server.Because the present invention repeatedly catches between server and another server, in information, identify, therefore can obtain many parts of files.
If adopt between secondary capturing server and another server, in information, identify, can obtain at most two parts of files.If adopt to catch for three times between server and another server, in information, identify, can obtain at most three parts of files.
Two parts of files have been preserved in judgement at least, perform step 208; Otherwise, finish.
Step 208, by again preserving file verification, preserve first file.
Owing at least preserving the file being sent to another server by two parts of servers, the file preserved under normal circumstances should be identical.But in order to guarantee the correctness of file, utilization is again preserved file verification and is preserved first file.
Verification mode has following two kinds:
The one, when preserving the file that server sends to another server, the file of being preserved first by the file verification of again preserving.
The 2nd, preserving server after the file of another server transmission, the file of being preserved first by the file verification of again preserving.
Concrete verification implementation is prior art, repeats no more herein.
In the situation that network state is good, server and another server carry out tertiary information mutual after, at server mappings port, monitor, can obtain at most three parts of files.Same, can to utilize the file verification of preserving for the second time to preserve first file, the file that also can utilize the file verification of preserving for the third time to preserve first.In essence, be all the file that utilizes again the file verification of preserving to preserve first.
Take below and utilize in SIP tertiary information to carry out alternately IP recording to be example, technical scheme of the present invention is described.Referring to accompanying drawing 3, be to utilize the tertiary information in SIP to carry out alternately the schematic diagram of IP recording.
IVR cluster sends voice messaging by LAN switch to SoftCAD, and voice server is done mirror image at the unified port of LAN switch.By this mirror image, the content that user and attending a banquet is passed through extracts and forms local recording file with the form of IP packet capturing.The total tertiary information of IVR cluster and SoftCAD is mutual, is respectively Invite message, 200k message and ACK message, by the sign of catching in above-mentioned message, is that Callid can start and prepare to preserve recording.When preserving at least two parts of recording, the recording that can be preserved first by the recording verification of again preserving.
According to current IP recording scheme, in the situation that there is no follow-up guarantee, only at IVR cluster and SoftACD, not monitor during information interaction for the first time, the success rate of recording is 99%, has 1% Invite information drop-out.And monitor when mutual at IVR cluster and SoftACD tertiary information according to the technical scheme in the present invention, the in the situation that of 1%Invite information drop-out, with 200K message, ensure, again to do triple guarantees with ACK message in the situation of 1%200K information drop-out, IP recording success rate is 1-(1%*1%*1%)=99.999999% simultaneously.
