Description
Technical field
The present invention relates to mobile communication technology field, more particularly to a kind of end-to-end association realization method and system.
Background technology
With the rapid development of China Mobile's business, signaling monitoring system is also comprehensively applied and developed, and is
The network operation of operator, routine optimization, processing is complained, accident monitoring provides strong instrument and data supporting,
To improve network quality, improve client perception and played great function.With the continuous expansion of signaling monitoring system monitoring range
With the whole network detection requirement, the signaling process association of distinct interface turns into the essential demand and key technology of monitoring signaling.With
IMS（Interactive Multimedia Service, interactive multi-media service）The rise and construction of network, IMS nets
If the monitoring signaling of network can not realize each Interface Flowchart association analysis, it will the maintenance analysis efficiency of IMS network and business is reduced,
Make IMS industrialization maturing courses slack-off.
In common signaling process, the signaling process approach BSC of caller（Base Station Controller, base station
Controller）To MSC（Mobile Switching Center, mobile switching centre）Mc interface, MSC to HLR（Home
Location Register, home location register）C/D interfaces, MS（Mobile Station, mobile station）To BSC Um
With Abis interface etc.；The signaling process of different interfaces is completed into association, that is, realizes the signaling of the distinct interface of same call
Flow merges, the as association of distinct interface；In other words, the signaling process of the distinct interface of same call is completed into association, i.e.,
Associated for distinct interface.Specific call flow is as follows：
Calling user dials called number, A interfaces SCCP is established by BSC where caller（Signaling
Connection and Control Part, signaling connection control protocol）Connection, MSC sends service request and disappeared where to caller
Breath；
MSC where caller returns connection confirmation message to BSC where caller；
If VLR where caller（Visitor Location Register, VLR Visitor Location Register）There is no available authentication
Collection, then the request for taking authentication to collect is sent to HLR where caller；
HLR where caller returns to authentication collection to VLR where caller；
MSC sends authentication request message to caller mobile phone where caller, starts authorizing procedure, is included in authentication request message
One random number and key sequence number CKSN；
Caller mobile phone loopback authentication response message gives caller place MSC, and an answer number SRES, caller are included in the message
Whether the SRES that place MSC compares in the SRES and authentication response message of oneself preservation is consistent, authenticates and passes through if consistent；
MSC where caller is ordered to BSC hairs encryption where caller, and desired AES and key is included in the message
Kc, and whether require that mobile phone is completed to include IMEI in encryption；
Start encryption mode transmission, BSC where caller returns to encryption completion message to MSC where caller；
MSC loopback traffic received messages where caller；
Caller mobile phone sends out call setup message, and the key messages such as called number, bearing capacity are carried in the message；
Call proceeding, MSC sends out call proceeding to caller mobile phone where caller；
Establish and carry for caller, MSC selections idle circuit, Calling Side MGW is sent to by corresponding TID where caller
（Media GateWay, WMG）, it is desirable to association is created, Calling Side MGW is by TID and RTP（Real-time Transport
Protocol, real time transport protocol）Termination ID is added in the association created；
Calling Side MGW returns to REPLY message to MSC where caller, and the message includes association and the RTP terminals created
ID, IP address, port numbers；
BSC where CIC corresponding to TID is sent to caller by MSC by allocation request message where caller, request caller institute
It is that calling subscribe distributes radio speech channel resource in BSC；
BSC where caller completes the wireless channel foundation that calling subscribe carries voice, and MSC loopbacks where to caller distribute
Into message.
In general, calling and called multiple network elements of approach in calling procedure is completed, are related to various protocols, any one
Network element is possible to terminate this calling because of certain reason.It is assumed that associated without multistage, if it is desired to processing is complained, positioning net
First failure etc. needs to analyze the signaling process of each network element, and not only workload is huge, and is difficult whether differentiation is same exhale
The flow cried, easily makes a mistake.After completing association, it will be greatly improved in terms for the treatment of effeciency, processing accuracy, will be exhausted
It is most of to need artificial operation to be converted into equipment processing, artificial free is done into high-end analysis, while be other special topics point
Analysis provides data supporting.
At present, IMS network has been carried out conditional end-to-end association.For example, there have document to disclose to be a kind of based on SIP associations
The CALL-ID of each message of view（Call instance identifies）The system and method that field completes each interface conjunctionn of Session Initiation Protocol.Its
In, said system is included with lower part：SIP in IMS network（Session Initiation Protocol, session initiation association
View）Protocol interface, SIP flow interface equipments；The SIP flows interface equipment connects each interface of Session Initiation Protocol, completes data and adopts
Collection, key message processing, the association of each Interface Flowchart.Methods described includes：The storage of Session Initiation Protocol flow interface is exhaled comprising first object
It is record CDR in detail（Call Detail Record, call detail record）First CDR list of information items of item of information, it is described
First object CDR items of information identify comprising call instance（CALL-ID）；This method includes：SIP of the SIP flows interface to input
Process messages extraction call instance mark（CALL-ID）, the content as the first CDR items of information of generation；SIP flows interface is retrieved
Whether call instance mark that first object CDR item of information include extraction is had in first CDR list of information items（CALL-ID）, such as
Fruit has, then stores the incidence relation between the SIP process messages and corresponding first object CDR items of information；If it is not,
The first CDR items of information of generation are added in first CDR list of information items, and store the first of the SIP process messages and addition
Incidence relation between CDR items of information.
Specifically, during the present invention is realized, inventor has found that currently existing scheme has the disadvantage that：
Following defect be present in existing IMS network internal interface agreement flow correlating method and systems technology：1st, CALL-ID words
The information content that section includes is few, and CALL-ID fields are only capable of for completing to associate；2nd, the CALL-ID words of the same call of each interfaces of IMS
Segment value can change, and cause interconnected system to be correctly completed multistage association.Illustrating CALL-ID field values can change
Scene：The AS of the IMS network of China Mobile（Authentication Server, application server）Entity is using leaning against
Carry on the back user agent（B2BUA）, therefore after calling arrival AS, AS can be terminated, and this is called, and then initiates once new calling；It is so every
The secondary message by AS can change CALL-ID field values；So in the ims network if AS entities are used using back-to-back
Act on behalf of at family（B2BUA）, existing interconnected system will be unable to complete multistage association.

Brief description of the drawings
Fig. 1 is the end-to-end association implementation method principle flow chart that the embodiment of the present invention 1 provides；
Fig. 2 is that system structure diagram is realized in the end-to-end association that the embodiment of the present invention 2 provides.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.But embodiments of the present invention are unlimited
In this.
As shown in figure 1, the end-to-end association implementation method principle flow chart provided for the embodiment of the present invention 1, specific as follows：
Step 10, the signaling process of sip terminal communication distinct interface is obtained, decoding obtains VIA information therein, and records
Obtain the time of VIA information.
By SIP specification actual conditions, following information can be obtained, the message format of Session Initiation Protocol is as shown in the table：
By sip message form table it is known that VIA fields are record request message paths, it is route for response message
's；Therefore an interface is often passed through, VIA fields will record the relevant information of this interface, in order to which response message can be by former road
Return.According to VIA field definitions, caller is issued in called message, and the VIA fields in message are the network elements of additional approach successively
Path.It is shown in the following example：
The VIA fields that terminal issues P-CSCF are as follows：
Via:SIP/2.0/UDP10.185.68.116：27633；branch=z9hG4bK345625038；rport=
27633；
The VIA fields that P-CSCF issues S-CSCF are as follows：
Via:SIP/2.0/UDP10.185.68.4:5060;branch=z9hG4bKfrr4yr1mmorb4ebqmuq
peerup;Role=3;Dpt=7be2_16;TRC=ffffffff-ffffffff,SIP/2.0/UDP10.185.68.116:
27633;branch=z9hG4bK345625038;rport=27633；
The VIA fields that S-CSCF issues AS are as follows：
Via:SIP/2.0/UDP10.185.68.8:5060;branch=
z9hG4bK81vevx770zxmzt330x3xmt17f;Role=3;Dpt=7c64_16;TRC=5b33-ffffffff,SIP/
2.0/UDP10.185.68.4:5060;branch=z9hG4bKfrr4yr1mmorb4ebqmuqpeerup;Role=3;Dpt=
7be2_16;TRC=fffffff f-ffffffff,SIP/2.0/UDP10.185.68.116:27633;branch=
z9hG4bK345625038;rport=27633；
By analysing terminal to P-CSCF, P-CSCF to S-CSCF, S-CSCF to AS VIA fields can be drawn, arbitrarily
One interface is the subset of further interface, such as：Terminal is the subset of the VIA fields of further interface to P-CSCF VIA fields, P-
CSCF to S-CSCF VIA fields are the subsets of the VIA fields of further interface, the like.
In general, sip terminal is called, or sip terminal receives calls.Calling passes through in IMS network.Signaling is supervised
Signaling process and decoding that collecting device obtains distinct interface are surveyed, obtains VIA；And timestamp is beaten to message according to Beijing time,
Obtain the time.Signaling monitoring collecting device is issued end-to-end association by the VIA of acquisition and time, together with the message full dose information and taken
Business device.
Step 20, according to VIA information and time, the interior difference with the VIA information of preset duration before and after the time is searched for
The communications records of interface.
VIA and time of the end-to-end associated server according to signaling monitoring collecting device application, this is searched in contingency table
5 minutes before and after the individual time（Here 5 minutes are for example, actually this duration is a preset duration, are set as needed
It is fixed, all illustrated below exemplified by 5 minutes）VIA, obtain same call record distinct interface VIA.The structure of contingency table is such as
Shown in following table：
| TIME | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
| 0419112233456 | VIA |
In contingency table, table name defines according to the date of record data, and table name form is as follows：VIA20130419, represent record
VIA table, date are on April 19th, 2013.Actual waiting time is to assign to April 20 in 2013 in April 18 day 23: 50 in 2013
Day 0 point 10 minutes, the storage time all same of every table.
TIME represents the time of collection message；0419112233456 is meant that 19 days 04 month 11 points of 33 seconds 22 minutes 456 millis
Second；Filling is stabbed by the message time gathered.
VIA represents the VIA of collection；Filled by the VIA in the message that receives, VIA and TIME are two of same message
Different field.
Step 30, the communications records of the distinct interface with identical VIA information are merged into same communications records.
The data of distinct interface are merged into same calling.If the front and rear 5 minutes VIA without matching, associating
Increase this VIA and time in table.
The result that end-to-end associated server will obtain, key message is extracted as needed, and the field of extraction is generated
XDR tables, while XDR tables and initial data are sent to database.
It if there is multiple IMS networks, can be completed by IF2 interfaces, the interaction of different IMS network, form IMS network
End-to-end association.
The signaling process that distinct interface is associated by VIA fields is that the signaling process of distinct interface is entered by VIA fields
Row judges that both VIA fields whether there is subset relation（Note：Within the regular hour, such as 5 minutes.）, if it is present being
Same call, if there is no not being then same call.By above-mentioned analysis it is known that being associated by VIA fields, not only may be used
, can be with acquiring way network element and client-related information to complete multistage association, and these information can not be obtained by CALL-ID
Take.
So far, the flow that the end-to-end association of IMS network Session Initiation Protocol is completed by VIA fields terminates.
Furthermore, it is understood that the signaling process of distinct interface is associated into same calling by VIA fields, complete end-to-end
Association.But China Mobile's actual conditions are combined, the AS in the IMS network of China Mobile（Application server）It is one back-to-back
User agent（B2BUA）, when client's initiating business request, AS can be in this INVITE requests that locally terminate.Then AS is sent
One new INVITE is asked to S-CSCF, and new request has a new VIA, and the association of such distinct interface will be unable to
Into.By SIP specification and China Mobile's IMS network actual conditions, it can be seen that, a whole process will be by the calling of IMS domain
It is divided into 3 sections, every section possesses a different set of VIA.
As shown in calling of the whole process in IMS network, in IMS domain if calling and called are sip terminals, then every disappears
Breath at least need by AS network elements twice, and because the AS of China Mobile using back-to-back user agent, same
Message is in distinct interface by including at least 3 groups of different VIA, such as in upper figure, INVITE message 1,2,3 uses one group of VIA, warp
INVITE4,5,6,7 use a VIA after crossing AS, and INVITE8,9,10 use a VIA after AS；As can be seen here, use
VIA fields can not associate the distinct interface of same calling；Similarly China Mobile can not be completed using CALL-ID fields
IMS domain same calling distinct interface related job, i.e., the prior art mentioned in Part III can not
End-to-end related job is realized in the IMS network of China Mobile.But if we will be got up by AS message relating, that
The distinct interface of same calling is associated together by can by VIA.Such as：How INVITE3 message and
INVITE4 message relatings into same calling, in other words S-CSCF how by INVITE3 message and INVITE4 message relatings into
Same calling.
According to Session Initiation Protocol, when S-CSCF and AS are interacted, there is sign to per call, conversation message can be passed through
ROUTE fields complete the association of interaction message.
The INVITE message that S-CSCF issues AS is as follows：
INVITE sip：114；phone-context=+86-311@ims.he.chinamobile.com；user=
phone SIP/2.0；
Via：
SIP/2.0/UDP10.185.68.8:5060；branch=z9hG4bK81vevx770zxmzt330x3xmt17f；

Call-ID:asbc1071540344@10.129.225.124；
The INVITE message that AS issues S-CSCF is as follows：
INVITE tel:+86311114SIP/2.0
Via:
SIP/2.0/UDP 10.185.68.231:9030；branch=z9hG4bK-d8754z-

Call-ID:NjM1YjU5MjYyZGMzZTIwY2ZkMzQwNjc4NmJiOTA0NTg。
Can be drawn by AS two message received and dispatched can not complete end-to-end association by VIA fields, similarly pass through AS
Two message of transmitting-receiving can be drawn can not complete end-to-end association by CALL-ID fields, while can be seen that CALL-ID words
The key message that section includes is few, is only capable of for completing related job.
The ROUTE fields that two INVITE messages are extracted by SIP specification are as follows：
The Route fields of S-CSCF to AS INVITE message are as follows：
Route:<sip:as1.centrex.he.chinamobile.com;lr;orig>,<sip:10.185.68.8;
lr;OR GDLGID=20875-1;Dpt=7c64_6;TRC=5b33-ffffffff>
The Route fields of AS to S-CSCF INVITE message are as follows：
Route:<sip:10.185.68.8;lr;ORGDLGID=20875-1;Dpt=7c64_6;TRC=5b33-ff
ffffff>
The second jump address in the Route message of Session Initiation Protocol S-CSCF to AS INVITE message is AS address,
Address in the Route message of AS to S-CSCF INVITE message is AS address.Contrast AS addresses and BRANCH can be sent out
Existing, both are completely the same, meet Session Initiation Protocol.Contrast is as follows：
The Route of S-CSCF to AS INVITE message：
<sip:10.185.68.8;lr;ORGDLGID=20875-1;Dpt=7c64_6;TRC=5b33-ffffffff>
The Route of AS to S-CSCF INVITE message：
<sip:10.185.68.8;lr;ORGDLGID=20875-1;Dpt=7c64_6;TRC=5b33-ffffffff
Drawn by SIP specification and live call tracking, the message between S-CSCF and AS, Route words can be passed through
The same calls of Duan Guanlian.
Interface between end-to-end associated server monitoring S-CSCF and AS, completes the VIA of same call association, is formed
Following VIA multistage contingency tables：
| TIME1 | VIA1 | TIME2 | VIA2 |
| 0419112233456 | VIA1 | 0419112233456 | VIA2 |
| 0419112233456 | VIA1 | 0419112233456 | VIA2 |

| 0419112233456 | VIA1 | 0419112233456 | VIA2 |
| 0419112233456 | VIA1 | 0419112233456 | VIA2 |
In VIA multistage contingency tables, table name defines according to the date of record data, and table name form is as follows：VIA20130419,
Record VIA table is represented, the date is on April 19th, 2013.Actual waiting time is to assign to 2013 April 18 day 23: 50 in 2013
10 minutes April 20 day 0 point of year, the storage time all same of every table.
TIME1 represents that AS receives the time of message；0419112233456 be meant that 19 days 04 month 11 points 33 seconds 22 minutes 456
Millisecond；Filling is stabbed by the message time received.
VIA1 represents the VIA that AS is received；Filled by the VIA in the message that receives, VIA1 and TIME1 are same message
Two different fields.
TIME2 represents that AS sends the time of message；0419112233456 be meant that 19 days 04 month 11 points 33 seconds 22 minutes 456
Millisecond；Filling is stabbed by the message time sent.
VIA2 represents the VIA that AS is sent；Filled by the VIA in the message that sends, VIA2 and TIME2 are same message
Two different fields.
Every a line record in upper table, TIME1, VIA1, TIME2, VIA2 are passed through such as by monitoring AS messaging
The different VIA records of the upper described same call associated by ROUTE fields, can be defined uniquely by TIME1 and VIA1
One calling.Two sections of correlation of call of one calling can be got up by TIME1, VIA1, TIME2, VIA2.
By searching for for 5 minutes up and down to VIA multistage contingency tables, the end-to-end association of same call is completed.
Similarly, CALL-ID related job by the above method, can be completed, in other words showing in Part III statement
There is technical scheme, if it is desired to completing the end-to-end association of the IMS network of China Mobile, it is necessary to based on above-mentioned technical proposal.
Specifically, end-to-end association realization is completed to comprise the following steps：
Sip terminal is called, or sip terminal receives calls.
Calling passes through in IMS network.
Signaling monitoring collecting device obtains the signaling process of distinct interface and decoding, obtains VIA；And according to Beijing time pair
Message beats timestamp, obtains the time.End-to-end associated server monitoring AS messaging, the VIA of same call is filled into
In VIA multistage contingency tables.
Signaling monitoring collecting device is according to the VIA of the distinct interface of parsing and obtained time, to end-to-end association service
The different section VIA of device application same call.
VIA and time of the end-to-end associated server according to signaling monitoring collecting device application, in VIA multistage contingency tables
The VIA of 5 minutes before and after this time is searched for, obtains the VIA of the different phase of same call record.It is meanwhile new whenever obtaining
During VIA, end-to-end associated server according to newly VIA and time is obtained, will re-search for the record of 5 minutes before and after this record, directly
Untill it can not obtain new VIA.
Obtained result is issued signaling monitoring collecting device by end-to-end associated server.
Signaling monitoring collecting device combines according to obtained VIA, completes the related job of the same call of distinct interface.
Signal collecting equipment is according to setting, it would be desirable to the field generation XDR tables of extraction, and XDR and initial data are sent to
Database.
If there is multiple IMS networks, the interaction of different IMS network can be completed by IF2 interfaces, forms IMS network
End-to-end association.
So far, application server uses back-to-back user agent（B2BUA）The flow of the end-to-end association of IMS network terminates.
As shown in Fig. 2 realizing system for the end-to-end association that the embodiment of the present invention 2 provides, the system decodes including information
