(3) -1：For each business process map, by recording Field Inquiry initial address message IAM and the address of type of message
Totally disappeared the message pair of breath ACM composition, and, record each message pair initial address message IAM respectively and reach this signaling data
The time IAMtime of collection point and Address Complete Message ACM reaches the time ACMtime of this signaling data collection point；
(3) -2：Calculate time difference time_interval of each request and response message pair, that is,：Time_interval=
ACMtime-IAMtime；If time_interval ＜ 0, it is considered as this request with response message to this signaling data of arrival
The sequencing of collection point occurs in that entanglement, and will appear from the time difference of entanglement and be designated as time_interval_fail；Otherwise regard
To the sequencing reaching this signaling data collection point, entanglement does not occur with response message for this request；
(3) -3：Repeated execution of steps (3) -1, (3) -2, until traveling through all business process maps, adds up request and response message pair
Total quantity m, the request of entanglement and quantity n of response message pair in accumulative this signaling data collection point sequencing that reaches,
Time difference time_ of entanglement to the sequencing reaching this signaling data collection point to record in request and response message every time
interval_faili, i=1,2,3 ... n；
(3) -4：Account for ratio f of total message number of times using the number of times that entanglement in following formula calculating sequencing：
If the number of times that entanglement in sequencing accounts for ratio f of total message number of times more than 10%, it is considered as this link signalling number
Occur in that time delay according to collection and it needs to carry out time delay correction, continue executing with following correction step；Otherwise, it is considered as this link letter
Make data acquisition not need to carry out time delay correction, terminate the time delay correction of epicycle, switch to execution step (5)；
(4) time delay correction is carried out to the collection of this signaling data, including：
(4) -1：Average delay correction is calculated using following formula：
In formula：A is link average delay correction；N is to reach the request that entanglement in this signaling data collection point sequencing
Quantity with response message pair；time_interval_failiAdopt to reaching this signaling data with response message for each request
The time difference of entanglement in the sequencing of collection point；
(4) -2：The acquisition time adjusting module of the harvester of tested link acquisition signaling data is adjusted so as to adopt
Automatically average delay correction A is deducted during collection signaling data；
(4) -3：Repeated execution of steps is (1) to (3)；
Adopt step (1) to step (4) methods described to this tested link signalling data collection point centering opposite side signaling number
Signaling data according to collection point collection carries out time delay correction；
(6), after tested link signalling data collection point centering two side data collection point all completes time delay correction, terminate this letter
Make data acquisition single-link time delay correction.
