By taking call flow as an example, as shown in Fig. 2, for the signaling process of SIP call flow intermediate cam signaling in the prior art
Figure, the SIP triangle signaling include: calling service network element SCSCF, called service network element SCSCF and inquiry network element ICSCF；One
Secondary call flow is called from calling UE to called SCSCF, initially by triangle network element caller SCSCF, ICSCF, called SCSCF
Request invite, its 180 responses, 200 responses all have passed through triangle network element caller SCSCF, ICSCF, called SCSCF, but new
200 responses of message prack and prack are without ICSCF, because ICSCF is proxy network element, agreement regulation is only initially asked
Ask invite and its response can be by ICSCF, subsequent request and response are without ICSCF.If only to caller SCSCF and
The interface of ICSCF carries out SIP signalling analysis, or only carries out SIP signalling analysis to the interface of ICSCF and called SCSCF, only
Invite can be analyzed and it is responded, process is imperfect；If only to the interface of caller SCSCF and called SCSCF into SIP signaling
Analysis, can only obtain part messages in process, can not analyze entire flow；Therefore a kind of method of whole binding analysis is needed.
As shown in figure 3, that is, signalling analysis system may be only for the signaling process figure of " incomplete triangle process " in the prior art
The signaling of half network element is collected, such as in Fig. 3, signalling analysis system can only collect endless between caller SCSCF and ICSCF
Imperfect signaling between whole signaling, caller SCSCF and called SCSCF lacks signaling between ICSCF to called SCSCF, this field
Scape can not be also analyzed and processed using the prior art.
In the present embodiment, when carrying out the processing of triangle call signaling, signaling process is according to call flow and conversation recording
Double-layer structure is associated processing.Wherein table 1 is an example of a call flow table:
| Call flow table |
| Callid |
| From-tag |
| To-tag |
| Sessionnum |
| Session[1] |
| Session[2] |
| Session[3] |
| Session[4] |
Table 1
In table 1, increase session [4] information in call flow record, which is virtual session record.
| Conversation recording table | Table content |
| Session[1] | Sip1 |
| Dip1 | |
| Direct1 | |
| Triangleflag=NULL | |
| Session[2]/Session[4] | Sip2 |
| Dip2 | |
| Direct2 | |
| Triangleflag=fulltriangle | |
| TriangleIndex=0x1 | |
| RelatedSession=3 | |
| Session[3] | Sip3 |
| Dip3 | |
| Direct3 | |
| Triangleflag=halftriangle | |
| TriangleIndex=0x1 | |
| RelatedSession=2 |
Table 2
Accordingly, table 2 is an example of a conversation recording table, increases virtual session record session [4],
It is to share an entity conversation recording with conversation recording session [2], setting mark Triangleflag=
Fulltriangle, i.e., complete triangle signaling mark, setting TriangleIndex=0x1 identifies 0x1 triangle calling, and sets
Set the half of conversation recording index RelatedSession=3 of association.And the setting in association one side of something conversation recording session [3]
Triangleflag=halftriangle is identified, i.e., half of triangle signaling mark, setting TriangleIndex=0x1 is identified
0x1 triangle calling, and the complete conversation recording index RelatedSession=2 of association is set.
In the present embodiment, a call signaling is received, creates call flow according to callid+from-tag+to-tag
Table record, the multistage session signaling of the call of identical callid+from-tag+to-tag are all registered under the flow table；
The call flow of multistage session is created according to sip+dip+direct (sip is source ip source IP, and dip is destination)
Multiple conversation recording tables, under the flow table for all hanging over a callid+from-tag+to-tag.Caller SCSCF is encountered to arrive
The initial request invite demand signalling of ICSCF creates a conversation recording, does key using the main scscf+dip-icscf of sip-
Word, this is left half of conversation recording；When encountering the subsequent response signaling of caller SCSCF to ICSCF, sip-scscf+dip- is used
Icscf can inquire this conversation recording, make requests and response is handled.ICSCF is encountered to the initial of called SCSCF
Invite signaling creates a conversation recording, does keyword by scscf using sip-icscf+dip-, this is right half of session note
Record；When encountering subsequent response signaling of the ICSCF to called SCSCF, it can be inquired using sip-icscf+dip- by scscf
This conversation recording, makes requests and response is handled.When there is triangle signaling, i.e. subsequent request of the caller SCSCF to called SCSCF
Signaling can not inquire conversation recording by scscf using the main scscf+dip- of sip-；But use the main scscf+ of one side of something sip-
From-tag can inquire the main scscf+dip-icscf record of left one side of something conversation recording i.e. sip-；Use half of dip- quilt
Scscf+to-tag can inquire right one side of something conversation recording i.e. sip-icscf+dip- and be recorded by scscf.It can estimate current
Triangle signaling scene is encountered, creates a bottom edge conversation recording, the main scscf+dip- of sip- does keyword by scscf, subsequent
Request and corresponding response can inquire this conversation recording by scscf using the main scscf+dip- of sip-, carry out subsequent request
With corresponding response processing.If a call flow message is split to assign to the left side, the right, three, bottom edge conversation recording, and each
Record can only all obtain part of signaling, and information is all seriously lost.Therefore, remember using bottom edge conversation recording as virtual session
Record and the left side (if the left side is not present, just and the right), which merge, shares an entity conversation recording, is complete session note
Record, all signalings of the complete available process of conversation recording, processing information are complete, accurate.Meanwhile the complete conversation recording mark
Knowing is complete triangle conversation recording, is registered with corresponding the right conversation recording index；The right conversation recording is identified as half of session note
Its complete conversation recording index is also registered in record；They possess identical triangle calling number, so that upper-level system is in processing
Time can be associated with two session informations and carry out；In data processing, they are mutually notified, cooperate statistics.For example, complete session
Record can receive session release BYE message, and (the right conversation recording can not receive subsequent request to the conversation recording release of notice the right
It is responded with corresponding).When counting the number of calls, complete conversation recording statistics is a triangle calling, the right conversation recording statistics
It is called for primary half of triangle, the calling reported carries identical triangle calling number, and expression is two of the same triangle calling
Record, is voluntarily calculated after reporting by operation system as needed, is calculated as 2 callings or call.Call setup
Afterwards, ACK message is received, complete conversation recording enters stable calls state, continues subsequent request and corresponding response processing；The right meeting
Words record can according to need releasing session record, report primary half of conversation recording because do not have subsequent message using
The right conversation recording；It can continue to hang, when complete conversation recording being waited to discharge, right half of conversation recording notified to discharge,
It can be handled according to business demand.So far, triangle signaling process is successfully processed, and is normally carried out data statistics, analysis.
As shown in figure 4, in the present embodiment, the step S10 includes:
The signaling that S11, acquisition access, and identify the interface and agreement of signaling；
S12, it packages to the signaling fragment, forms complete SIP signaling；
S13, the first decoding is carried out to the critical field of the SIP signaling, carries out signaling distribution according to session；
S14, the second decoding is carried out to the SIP signaling after distribution, obtain the field information of SIP signaling；
S15, according to the field information to the SIP signaling after the distribution conversate service logic analysis processing, build
Vertical call flow table.
In the present embodiment, it described first is decoded as quickly decoding, only critical field is decoded, to help signaling point
Hair；Described second is decoded as decoding in detail, to obtain field information.
In the present embodiment, the step S40 includes following two situation:
Bottom edge virtual session record and left side conversation recording are merged into a complete conversation recording, are set as complete
Triangle signaling session identification；Half of triangle signaling session identification is set by the right conversation recording；Or
The bottom edge virtual session record and the right conversation recording merge into a complete conversation recording, are set as complete three
Angle signaling session identification；Half of triangle signaling session identification is set by left side conversation recording.
That is, virtual session record in bottom edge can both merge into a complete conversation recording with left side conversation recording,
A complete conversation recording can also be merged into the right conversation recording, preferentially select left side conversation recording.
In the present embodiment, the step S50 includes:
Judge whether the signaling in the SIP triangle signaling is initial request, if so, passing through half of triangle signaling session
Mark is analyzed and processed the signaling；
Otherwise, if the signaling in the SIP triangle signaling is subsequent request or the corresponding response of subsequent request, passed through
Whole triangle signaling session identification is analyzed and processed the signaling.
In the present embodiment, in call flow, the SIP triangle signaling includes: calling service network element, called service network
Member and inquiry network element, the signaling between the calling service network element and inquiry network element create left side conversation recording；The called clothes
The signaling creation the right conversation recording being engaged between network element and inquiry network element；Between the calling service network element and called service network element
Signaling creation bottom edge virtual session record.
Still by taking call flow as an example, as shown in figure 5, the process of SIP triangle signaling in this case call flow is discussed in detail,
Calling UE initiates SIP calling, sends Invite signaling and gives PCSCF network element, indicates to carry out call.PCSCF forwarded call, hair
(SM1) Invite signaling is sent to give caller SCSCF network element；Caller SCSCF network element sends (SM2) Invite signaling and gives ICSCF network element,
ICSCF network element inquires called ownership SCSCF, sends (SM3) Invite to called SCSCF network element, is called SCSCF forwarded call
Invite gives callee side related network elements.Callee side returns to 180 and responds to called SCSCF, is called SCSCF forwarding (SM6) 180 and responds
To ICSCF, ICSCF forwarding (SM7) 180 responds to caller SCSCF, and caller SCSCF forwarding (SM8) 180 responds to Calling Side net
Member.Calling Side network element returns to Prack request (the Provisional Response ACKnowledgement, for reliable
Temporary Response message confirmation), which is transmitted to caller SCSCF, and caller SCSCF is to subsequent request
(SM10) Prack is directly forwarded to called SCSCF, is no longer pass through called ICSCF.Called SCSCF forwarding request (SM11) Prack
Give callee side network element.Callee side return (SM12) Prack-200 response, be called SCSCF forwarding (SM13) Prack-200 directly to
Caller SCSCF, without ICSCF.Callee side returns to (SM15) Invite-200 response, is called SCSCF forwarding (SM16)
Invite-200 is to ISCSCF, and ICSCF forwarding (SM17) Invite-200 give caller SCSCF, by ICSCF.After session establishment,
Subsequent request and response are without ICSCF.
In the present embodiment, PCSCF is agent network element, in Calling Side is tentatively accessed as the IMS of calling UE when session
Mouth point can forward messages to called UE by called PCSCF in callee side；SCSCF is service network element, and caller callee side is all
It uses, completes the Call-Establish-Success rate of this side, business triggering；ICSCF is inquiry network element, and only callee side is used, called network
Preliminary entrance.
As another embodiment, the triangle signalling analysis device be also applied for call flow with for other processes,
For example, subscribe process, can also be with same treatment there is also triangle signaling scene etc. in register flow path.
Embodiment two
As shown in fig. 6, in the present embodiment, a kind of triangle signalling analysis device, comprising:

The initial request invite demand signalling of ICSCF creates a conversation recording, does key using the main scscf+dip-icscf of sip-
Word, this is left half of conversation recording；When encountering the subsequent response signaling of caller SCSCF to ICSCF, sip-scscf+dip- is used
Icscf can inquire this conversation recording, make requests and response is handled.ICSCF is encountered to the initial of called SCSCF
Invite signaling creates a conversation recording, does keyword by scscf using sip-icscf+dip-, this is right half of session note
Record；When encountering subsequent response signaling of the ICSCF to called SCSCF, sip-icscf+ is used
Dip- can inquire this conversation recording by scscf, make requests and response is handled.When there is triangle signaling,
That is caller SCSCF can not inquire meeting by scscf using the main scscf+dip- of sip- to the subsequent request signaling of called SCSCF
Words record；But the main scscf+ of left one side of something conversation recording i.e. sip- can be inquired using the main scscf+from-tag of half of sip-
Dip-icscf record；Right one side of something conversation recording i.e. sip-icscf+ can be inquired by scscf+to-tag using half of dip-
Dip- is recorded by scscf.It can estimate and currently encounter triangle signaling scene, create a bottom edge conversation recording, the main scscf of sip-
+ dip- does keyword, subsequent request and corresponding response by scscf, can be looked into using the main scscf+dip- of sip- by scscf
This conversation recording is ask, subsequent request and corresponding response processing are carried out.If a call flow message is split to assign to the left side, the right side
Side, three, bottom edge conversation recording, and respectively record and can only all obtain part of signaling, information is all seriously lost.Therefore, the bottom of
Side conversation recording is recorded as virtual session and the left side (if the left side is not present, just and the right) merges and share a reality
Body conversation recording is complete conversation recording, all signalings of the complete available process of conversation recording, and processing information is complete, quasi-
