Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, in this embodiment, a method for analyzing a triangular signaling is provided, including:

S10. Receive SIP signaling, and establish a call flow table according to the SIP signaling.

S20: Determine whether the SIP signaling is SIP triangular signaling, and if yes, execute S30, and create a left session record, a right session record, and a bottom virtual session record in the call flow table;

S40. Combine the bottom virtual session record and the left session record into a complete session record, or merge the bottom virtual session record and the right session record into a complete session record, and set a complete triangle letter corresponding to the complete session record. Let the session identifier; the half-edge triangular signaling session identifier corresponding to the right session record or the left session record setting of the complete session record;

S50. Analyze the SIP triangle signaling by using the complete session record and the half session record.

In an embodiment, if the SIP signaling is not SIP triangular signaling, the process proceeds to step S60, and the complete triangular signaling session identifier is not set.

In this embodiment, by dividing the triangular signaling into a complete session record and a half session record, the two cooperate with each other, notify each other, and jointly analyze and process the triangular signaling, thereby improving the accuracy and rationality of the analysis process. Achieve full process management.

Taking the call flow as an example, as shown in FIG. 2, it is a signaling flowchart of the triangular signaling in the SIP call flow in the prior art, and the network element involved in the SIP triangular signaling includes: the SCSCF as the calling service network element. As the called service network element SCSCF and the inquiry network element ICSCF; one call flow, through the calling SCSCF, ICSCF and called SCSCF, the call from the calling UE to the called SCSCF, initial request (invite) signaling, initial request (invite) signaling 180 response signaling, initial request (invite) signaling 200 response signaling has passed through the calling SCSCF, ICSCF and called SCSCF, but subsequent request (prack) signaling and subsequent request (prack) 200 response signaling does not pass through the ICSCF. Because the ICSCF is a proxy network element, the protocol specifies that only the initial request (invite) signaling and the initial request (invite) response signaling will pass through the ICSCF, subsequent request signaling and response signaling. Does not pass the ICSCF. If the SIP signaling analysis is performed only on the interface between the calling SCSCF and the ICSCF, or only the SIP signaling analysis is performed on the interface between the ICSCF and the called SCSCF, only the invite signaling and the invite response signaling can be analyzed. The process is incomplete. If only SIP signaling analysis is performed on the interface between the calling SCSCF and the called SCSCF, only some messages in the process can be obtained, and the complete process cannot be analyzed; therefore, a method of overall combined analysis is needed.

As shown in FIG. 3, it is a signaling flowchart of the “removed triangle flow” in the prior art, that is, the signaling analysis system may only collect signaling of half of the network elements. For example, in FIG. 3, the signaling analysis system can only collect. Incomplete signaling between the calling SCSCF and the ICSCF, incomplete signaling between the calling SCSCF and the called SCSCF, and lack of signaling between the ICSCF and the called SCSCF. This scenario cannot be analyzed and processed by the prior art. .

In this embodiment, when the triangle call signaling processing is performed, the signaling process performs association processing according to the call flow and the session record two-layer structure. Table 1 is an example of a call flow table:

Table 1

In Table 1, a Session[4] message is added to the call flow record, and the Session[4] represents a virtual session record.

Session record 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

Correspondingly, Table 2 is an example of a session record table. Add a virtual session record Session[4], and use the session record Session[2] to use an entity session record, and set the identifier Triangleflag=fulltriangle, that is, the complete triangle signaling identifier. Set TriangleIndex=0x1 to identify 0x1 triangle calls and set the associated half session record index RelatedSession=3. And set the identifier Triangleflag=halftriangle in the associated half session record Session[3], that is, the half triangle signaling identifier, set TriangleIndex=0x1 to identify 0x1 triangle call, and set the associated complete session record index RelatedSession=2.

In this embodiment, a call signaling is received, and a call flow table record is created according to callid+from-tag+to-tag, and the multi-session session signaling of a call of the same callid+from-tag+to-tag is registered to The flow chart of the multi-session session is based on sip+dip+direct (sip is source ip source IP, dip is destination) to create multiple session record tables, all hanging in a callid+from-tag+to-tag process Below the table. The initial request invite request message from the calling SCSCF to the ICSCF creates a session record, using sip-main scscf+dip-icscf as the key, which is the left half session record; encounters the subsequent response letter from the calling SCSCF to the ICSCF When you use sip-scscf+dip-icscf, you can query this session record for request and response processing. The initial invite signaling of the ICSCF to the called SCSCF is created to create a session record, using sip-icscf+dip-by scscf as the key, which is the right half session record; when encountering the subsequent response signaling from the ICSCF to the called SCSCF Use sip-icscf+dip-scsc to query this session record for request and response processing. When the triangle signaling occurs, that is, the subsequent request signaling from the calling SCSCF to the called SCSCF, the sip-main scscf+dip- can not be queried by the scscf to the session record; but the half sip-main scscf+from-tag can be used to query The left half of the session record is the sip-main scscf+dip-icscf record; using the half-dip-scsccftoto-tag can query the right half of the session record ie sip-icscf+dip-recorded by scscf. It can be presumed that the triangle signaling scenario is currently encountered, and a bottom-side session record is created. The sip-main scscf+dip- is the keyword of scscf, the subsequent request and the corresponding response, and the sip-main scscf+dip- can be queried by scscf. Go to this session record for subsequent requests and corresponding response processing. If a call flow message is split into three session records on the left, right, and bottom sides, and each record can only obtain part of the signaling, the information is seriously lost. Therefore, the bottom session record is recorded as a virtual session record, and the left side (if the left side does not exist, then the right side) merges to share an entity session record, called a complete session record, which can obtain all signaling of the process, and process information. Complete and accurate. At the same time, the complete session record identifier is a complete triangle session record, and the right session record index is registered; the right session record identifier is a half session record, and its complete session record index is also registered; they have the same triangle call number, so that the upper layer system Two session information can be associated with each other during processing; they notify each other and collate statistics during data processing. For example, a full session record can receive a session release BYE message, notifying that the right session record is released (the right session record cannot receive subsequent requests and corresponding responses). When counting the number of calls, the full session record is counted as a triangle call, and the right session record is counted as a half-triangle call. The reported call carries the same triangle call number, indicating that it is the same record of the same triangle call. Calculate as needed and count as 2 calls or one call. After the call is established, the ACK message is received, the complete session record enters the stable call state, and the subsequent request and the corresponding response process are continued; the right session record can release the session record as needed, and report a half session record, because there will be no subsequent messages. The session record on the right side; it can also continue to hang, waiting for the full session record release, notify the right half of the session record release, can be processed according to business needs. At this point, the triangular signaling process is successfully processed, and data statistics and analysis are performed normally.

Based on the above description, in the embodiment, in step S40, the left session record is created by the initial request signaling of the left session, and the session key of the left session record is set (the session keyword includes at least one of the following callid, ip1+from-tag) , ip2+to-tag); create a right session record by initial request signaling of the right session, set a session key of the right session record; create a bottom virtual session record from subsequent requests after the initial request, and set a bottom virtual session record Session keyword.

As shown in FIG. 4, in this embodiment, the step S10 includes:

S11. Collecting access signaling;

S12. If the signaling of the access is a signaling fragment, the signaling fragment is grouped to form a complete SIP signaling.

S13: Perform first decoding on the key segment of the SIP signaling, and distribute the decoded SIP signaling according to the session;

S14. Perform second decoding on the distributed SIP signaling, and obtain field information of the SIP signaling.

S15. Perform session service logic analysis processing on the distributed SIP signaling according to the field information, and establish a call flow table.

In this embodiment, the first decoding is fast decoding, and only the key segment is decoded. In actual applications, the key segment may be a call identifier (Callid) or the like to facilitate signaling distribution; The second decoding is detailed decoding to obtain field information.

In this embodiment, the step S40 includes the following two situations:

Combining the bottom virtual session record and the left session record into a first complete session record, setting a first complete triangle signaling session identifier corresponding to the first complete session record; and setting a first half triangle letter corresponding to the right session record Make the session identifier; or

Combining the bottom virtual session record and the right session record into a second complete session record, setting a second complete triangle signaling session identifier corresponding to the second complete session record; setting a second half triangle letter corresponding to the left session record Let the session be identified.

That is, the bottom virtual session record can be merged with the left session record into the first full session record, or merged with the right session record into the second full session record. In an embodiment, the priority can be pre-configured, for example, Priority is merged with the left session record; of course, the priority configuration is not limited to the above, and may be preferentially combined with the right session record, which is not limited in this embodiment.

In this embodiment, the step S50 includes:

Determining whether the SIP triangle signaling is signaling corresponding to the initial request; if yes, determining whether the signaling corresponding to the initial request belongs to a half-triangular signaling session processing; if yes, recording the SIP triangular letter through the half-session session Let the analysis process be performed to obtain the first processing result;

Determining whether the SIP triangle signaling is signaling corresponding to the initial request; if yes, determining whether the signaling corresponding to the initial request belongs to the completion of the triangular signaling session processing; if yes, recording the SIP triangular letter by using the complete session record Let the analysis process be performed to obtain the second processing result;

Otherwise, when the SIP triangle signaling is the signaling corresponding to the response corresponding to the subsequent request or the subsequent request after the initial request, the SIP triangle signaling is analyzed and processed by the complete session record.

Specifically, for the signaling corresponding to the initial request, as shown in FIG. 2, for example, an initial request (invite) message and a response message corresponding to the initial request (invite) message are two segments, that is, the calling SCSCF and the called SCSCF. The forwarding between the ICSCF has two initial request (invite) messages, and two response messages corresponding to the initial request (invite) message (ie, 180 response messages), then for the calling side, based on the initial request of the calling side ( The invite message creates a left session record, and for the called side, creates a right session record based on the initial request (invite) message of the called side; and after merging the complete session record, whether the complete session record is merged for the calling side or the called side, For the other side, it is still an incomplete left session record or a right session record; based on this, for the signaling corresponding to the initial request, the SIP triangle signaling needs to be analyzed and processed through the half session record and the complete session record.

For the signaling corresponding to the subsequent request after the initial request or the response corresponding to the subsequent request, as shown in FIG. 2, for example, a subsequent request (prack) message and a subsequent request (prack) message response message (prack-200 response message), For a segment, that is, a direct transmission between the calling SCSCF and the called SCSCF without forwarding by the ICSCF, the SIP triangular signaling is analyzed and processed by the complete session record for the type of signaling.

Specifically, as an implementation manner, the analyzing, by the complete session record and the half session record, the SIP triangle signaling includes:

Determining whether the SIP triangle signaling belongs to the signaling corresponding to the initial request of the left session record; when the SIP triangle signaling is the signaling corresponding to the initial request of the left session record, the first complete session is adopted. Recording and analyzing the SIP triangle signaling;

When the SIP triangle signaling is not the signaling corresponding to the initial request recorded by the left session record, determining whether the SIP triangle signaling belongs to the signaling corresponding to the initial request of the right session record; when the SIP triangle signaling When the signaling corresponding to the initial request recorded by the right session record is performed, the SIP triangle signaling is analyzed and processed by the first half session record;

When the SIP triangle signaling is the signaling corresponding to the response corresponding to the subsequent request or the subsequent request after the initial request, the SIP triangular signaling is analyzed and processed by the first complete session record.

In another implementation manner, the analyzing, by the complete session record and the half session record, the SIP triangle signaling includes:

Determining whether the SIP triangle signaling belongs to the signaling corresponding to the initial request of the left session record; when the SIP triangle signaling is the signaling corresponding to the initial request of the left session record, the second half session is adopted. Recording and analyzing the SIP triangle signaling;

When the SIP triangle signaling is not the signaling corresponding to the initial request recorded by the left session record, determining whether the SIP triangle signaling belongs to the signaling corresponding to the initial request of the right session record; when the SIP triangle signaling When the signaling corresponding to the initial request recorded by the right session record is performed, the SIP triangle signaling is analyzed and processed by the second complete session record;

When the SIP triangle signaling is signaling corresponding to the response corresponding to the subsequent request or the subsequent request after the initial request, the SIP triangular signaling is analyzed and processed by the second complete session record.

In this embodiment, in the call flow, the SIP triangle signaling includes: a calling service network element, a called service network element, and an inquiry network element; then, creating a left session record and a right side under the call flow table. The session record and the bottom edge virtual session record include: creating a left session record based on SIP initial request signaling and corresponding response signaling between the calling service network element and the querying network element; the initial request signaling and the corresponding response Also referred to as initial request signaling and corresponding response signaling of the left session record; creating a right session record based on SIP initial request signaling and corresponding response signaling between the called service network element and the querying network element; The request signaling and the corresponding response are also referred to as the initial request signaling and the corresponding response signaling of the right session record; a subsequent request letter after the SIP initial request signaling between the calling service network element and the called service network element Create and create a bottom virtual session record for the corresponding response signaling.

For example, as shown in FIG. 5, the process of the SIP triangle signaling in the call flow of the embodiment is described in detail. The calling UE initiates a SIP call, and sends an Invite signaling to the PCSCF network element, indicating that it is performed once. call. The PCSCF forwards the call, sends (SM1) Invite signaling to the calling SCSCF network element; the calling SCSCF network element sends (SM2) Invite signaling to the ICSCF network element, and the ICSCF network element queries the called home SCSCF, and sends (SM3) Invite To the called SCSCF network element, the called SCSCF sends (SM4) Invite to the associated network element on the called side. The called side returns a 180 response message (which can be recorded as (SM5) 180) to the called SCSCF, the called SCSCF sends (SM6) 180 response to the ICSCF, and the ICSCF forwards (SM7) 180 response to the calling SCSCF, and the calling SCSCF forwards ( SM8) 180 responds to the calling side network element. The calling side network element returns a PURL request (the Provisional Response ACKnowledgement for the reliable temporary response), the request (SM9) Prack is forwarded to the calling SCSCF, and the calling SCSCF requests the subsequent request (SM10) Prack is forwarded directly to the called SCSCF and no longer passes through the ICSCF. The called SCSCF forwards the request (SM11) to the called side network element. The called side returns (SM12) the Prack-200 response, and the called SCSCF forwards (SM13) the Prack-200 directly to the calling SCSCF without passing through the ICSCF; the calling SCSCF forwards (SM14) the Prack-200 to the PCSCF. The called side returns (SM15) Invite-200 response, the called SCSCF forwards (SM16) Invite-200 to the ISCSCF, the ICSCF forwards (SM17) Invite-200 to the calling SCSCF, passes through the ICSCF, and the calling SCSCF forwards (SM18) Invite- 200 to PCSCF. Subsequent requests and responses do not pass through the ICSCF after the session is established. That is, the PCSCF sends an acknowledgment (SM19) (Ack) message to the calling SCSCF; the calling SCSCF does not send (SM20) Ack message to the called SCSCF without forwarding through the ICSCF; the called SCSCF sends (SM21) Ack message to the called side network element. .

As another embodiment, the triangular signaling analysis device is also applicable to other processes that the call process considers. For example, the subscription process also has a triangular signaling scenario in the registration process, and the like.

The embodiment of the present invention further provides a triangular signaling analysis device. As shown in FIG. 6, the triangular signaling analysis device includes:

The signaling receiving module 10 is configured to receive SIP signaling, and establish a call flow table according to the SIP signaling;

The determining module 20 is configured to determine whether the SIP signaling is SIP triangular signaling, and if yes, create a left session record, a right session record, and a bottom virtual session record in the call flow table; otherwise, the setting is not required to be complete. Triangular signaling session identifier;

The setting module 30 is configured to merge the bottom virtual session record and the left session record into a complete session record, or merge the bottom virtual session record and the right session record into a complete session record, and set the complete session record correspondingly Complete triangle signaling session identifier; set the half-side triangular signaling session identifier corresponding to the right session record or the left session record that does not form a complete session record;

The analysis processing module 40 is configured to perform analysis processing on the SIP triangle signaling by using the complete session record and the half session record.

In this embodiment, by dividing the triangular signaling into a complete session record and a half session record, the two cooperate with each other, notify each other, and jointly analyze and process the triangular signaling, thereby improving the accuracy and rationality of the analysis process. Achieve full process management.

In this embodiment, when the triangle call signaling processing is performed, the signaling process performs association processing according to the call flow and the session record two-layer structure. Receiving a call signaling, creating a call flow table record according to callid+from-tag+to-tag, and multi-session session signaling of a call of the same callid+from-tag+to-tag is registered under the flow table; The session call flow creates multiple session record tables according to sip+dip+direct (sip is source ip source IP, dip is destination), and is hung in a callid+from-tag+to-tag flow table. The initial request invite request message from the calling SCSCF to the ICSCF creates a session record, using sip-main scscf+dip-icscf as the key, which is the left half session record; encounters the subsequent response letter from the calling SCSCF to the ICSCF When you use sip-scscf+dip-icscf, you can query this session record for request and response processing. The initial invite signaling of the ICSCF to the called SCSCF is created to create a session record, using sip-icscf+dip-by scscf as the key, which is the right half session record; when encountering the subsequent response signaling from the ICSCF to the called SCSCF Use sip-icscf+dip-scsc to query this session record for request and response processing. When the triangle signaling occurs, that is, the subsequent request signaling from the calling SCSCF to the called SCSCF, the sip-main scscf+dip- can not be queried by the scscf to the session record; but the half sip-main scscf+from-tag can be used to query The left half of the session record is the sip-main scscf+dip-icscf record; using the half-dip-scsccftoto-tag can query the right half of the session record ie sip-icscf+dip-recorded by scscf. It can be presumed that the triangle signaling scenario is currently encountered, and a bottom-side session record is created. The sip-main scscf+dip- is the keyword of scscf, the subsequent request and the corresponding response, and the sip-main scscf+dip- can be queried by scscf. Go to this session record for subsequent requests and corresponding response processing. If a call flow message is split into three session records on the left, right, and bottom sides, and each record can only obtain part of the signaling, the information is seriously lost. Therefore, the bottom session record is recorded as a virtual session record, and the left side (if the left side does not exist, then the right side) merges to share an entity session record, called a complete session record, which can obtain all signaling of the process, and process information. Complete and accurate. At the same time, the complete session record identifier is a complete triangle session record, and the right session record index is registered; the right session record identifier is a half session record, and its complete session record index is also registered; they have the same triangle call number, so that the upper layer system Two session information can be associated with each other during processing; they notify each other and collate statistics during data processing. For example, a full session record can receive a session release BYE message, notifying that the right session record is released (the right session record cannot receive subsequent requests and corresponding responses). When counting the number of calls, the full session record is counted as a triangle call, and the right session record is counted as a half-triangle call. The reported call carries the same triangle call number, indicating that it is the same record of the same triangle call. Calculate as needed and count as 2 calls or one call. After the call is established, the ACK message is received, the complete session record enters the stable call state, and the subsequent request and the corresponding response process are continued; the right session record can release the session record as needed, and report a half session record, because there will be no subsequent messages. The session record on the right side; it can also continue to hang, waiting for the full session record release, notify the right half of the session record release, can be processed according to business needs. At this point, the triangular signaling process is successfully processed, and data statistics and analysis are performed normally.
