For making the object of the invention, technical scheme and advantage express clearlyer, the present invention is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
In embodiments of the present invention, not only when server and another server are mutual for the first time, carry out, and when mutual and mutual for the third time for the second time, all carry out, thereby improved the success rate of monitoring at server and another server based on the SIP signaling monitoring.In addition, when preserving two parts of servers to the file that another server sends, can utilize the file that the file verification of preserving is once more preserved first, the correctness of the preservation file that further improves.
Referring to accompanying drawing 2 are embodiment of the invention schematic flow sheets based on the method for SIP signaling raising monitoring success rate, specifically may further comprise the steps:
Server sends the message first time that has sign to another server, monitors at the server mappings port, and the sign in catching the message first time is execution in step 202 then; Otherwise execution in step 203.Adopt the standard Session Initiation Protocol between server and another server.
Sign is different according to its title of different message, but the effect of sign mainly is to be 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 the message is a prior art, repeats no more at this.
Captured the sign in the message for the first time, then started and prepares to preserve file, for further preparing at server preservation file when another server sends file.
Start and also to prepare to preserve file, and do not mean that necessarily and can be saved in file.File is preserved in influence has multiple factor, in order to increase the success rate of preserving file, adopts in the present invention and monitors between server the repeatedly technical scheme of information interaction.
Another server sends the message second time that has sign to server, and same monitors at the server mappings port, and the sign in catching the message second time is execution in step 204 then; Otherwise, execution in step 205.
Sign in this step is identical with sign in the step 201.The repeatedly information interaction that can make full use of between server and another server is caught sign, and then monitors and to obtain the file that transmits between server and another server.Obtain file than only utilizing between server and another server for the first time information interaction to catch sign, the success rate that above-mentioned technical method obtains file improves greatly.
Caught the sign in the message for the second time, then started and prepares to preserve file, for further preparing at server preservation file when another server sends file.
Utilize server in the sip message to send the message for the third time that has sign to another server, same monitors at the server mappings port, and the sign in catching message for the third time is execution in step 206 then; Otherwise, finish.
It is very little all not capture the probability that identifies in the message for three times, and once not capturing the probability that identifies in the message is 1%, so three all not capture the probability that identifies in the message be 1%*1%*1%=0.000001.
Caught the sign in the message for the third time, then started and prepare to preserve file, prepared for further when another server sends file, preserving file at server.
Two parts of files have been preserved in step 207, judgement at least.
Server and another server carry out tertiary information mutual after, server sends file to another server.Monitor at the server mappings port, and then obtain the file that server sends to another server.Because the present invention repeatedly catches between server and another server and identifies in the information, therefore can obtain many parts of files.
Identify in the information if adopt between secondary capturing server and another server, then can obtain two parts of files at most.Identify in the information if adopt to catch between server and another server for three times, then can obtain three parts of files at most.
Judge and preserved two parts of files at least, then execution in step 208; Otherwise, finish.
Because preserve the file that is sent to another server by two parts of servers at least, the file of being preserved under the normal condition should be identical.But in order to guarantee the correctness of file, utilization is preserved file verification once more and is preserved file first.
Verification mode has following two kinds:
The one, when preserving server to file that another server sends, the file of preserving first by the file verification of preserving once more.
The 2nd, preserving server behind the file that another server sends, the file of preserving first by the file verification of preserving once more.
Concrete verification implementation is a prior art, and this paper repeats no more.
Under the good situation of network state, server and another server carry out tertiary information mutual after, monitor at the server mappings port, can obtain three parts of files at most.Same, as 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, all be the file that utilizes once more the file verification of preserving to preserve first.
Be example to utilize among the SIP tertiary information to carry out the IP recording alternately below, technical scheme of the present invention is described.Referring to accompanying drawing 3 are the sketch mapes that utilize the tertiary information among the SIP to carry out the IP recording alternately.
The IVR cluster sends voice messaging through LAN switch to SoftCAD, and voice server is done mirror image at the unified port of LAN switch.Through this mirror image, extract the user with the content passed through the form of attending a banquet and to form local recording file with the IP packet capturing.The total tertiary information of IVR cluster and SoftCAD is mutual, is respectively Invite message, 200k message and ACK message, is that Callid can start and prepare to preserve recording through the sign of catching in the above-mentioned message.When preserving at least two parts of recording, the recording that then can preserve first by the recording verification of preserving once more.
According to present IP recording scheme, not monitor during information interaction for the first time at IVR cluster and SoftACD only having under the situation of follow-up guarantee promptly, the success rate of recording is 99%, and 1% Invite information drop-out is arranged.And monitor when IVR cluster and SoftACD tertiary information are mutual according to the technical scheme among the present invention; Under the situation of 1%Invite information drop-out, ensure with 200K message; Again to do triple guarantees with ACK message under the situation of 1%200K information drop-out, then IP recording success rate is 1-(1%*1%*1%)=99.999999% simultaneously.
Referring to accompanying drawing 4 is that the embodiment of the invention improves the structural representation of monitoring success rate based on the SIP signaling, comprising:
Trapping module 402 is used for catching the sign of above-mentioned message, sends file message to logging modle 403 when capturing sign;
