Judge whether the number has as gray list place, wherein,
If matching allows its normal call not for gray list place has；
If matching is present in gray list storehouse, the signaling of the calling and media information are reached into back-end server through rear end
Server judges whether the calling number is harmful calling, if back-end server is judged to harmful calling, under back-end server
Say the word to headend equipment and intercepted, prevent the calling from continuing, if back-end server judges not to be harmful calling, allow it
Normal call.
Specifically, the present invention is main is blocked by signal collecting with acquisition of media, harmful calling judgement and harmful calling
Three steps are cut to confirm.
During the collection of signaling and acquisition of media, signaling is mainly bypassed and connects pattern reality by the use of existing network link
Now gather, acquisition mode is mirror image or light splitting, or the two mode for being combined.Media are mainly adopted by medium surface information
Collection, and the media information decoding that will be collected, are reduced to audio file.And decoded by agreement, complete signaling and matchmaker
The association of body.Pattern is bypassed and connects, headend equipment is and connects relation with equipment in network, and advantage is that headend equipment breaks down
The normal operation of the network equipment is not interfered with, and is capable of achieving without carrying out larger transformation to existing network.Mirror-image fashion is to construct
Mirror image link, makes the signal in the network equipment in addition to normal transmission, and its mirror image is sent into headend equipment.Spectroscopic modes are then directed to
The network equipment of signal transmission is carried out by optical-fiber network, optical splitting link is constructed, makes the optical signal in the network equipment except normal transmission
Outward, its light splitting is sent to headend equipment.
In harmful calling decision process, harmful calling judges mainly there is two ways.
The first decision procedure is that headend equipment is provided with blacklist storehouse, and headend equipment is carried out to the signaling information for collecting
Decoding Analysis, obtain the calling number in signaling, are matched with calling number with blacklist storehouse.Judge the number whether as black
List place has, if being located in blacklist storehouse, judges that the calling is harmful calling.
The second way is that the calling number that signaling information Decoding Analysis are obtained is not in blacklist storehouse, then use
The calling number is matched with doubtful harmful calling gray list storehouse, judges whether the number has as gray list place, if being located at
In gray list storehouse, then the signaling information of the calling number and media information are reached into back-end server, back-end server is exhaled this
It is called and to determine whether harmful calling, back-end server is judged to harmful calling, then intercept.
Wherein, before the judgement of harmful calling, headend equipment is by all call bill report to back-end server, rear end
Server carries out independent or comprehensive analysis to outside input feature vector, Signaling characteristics and behavioural characteristic, to doubtful harmful calling
Generation gray list is issued to headend equipment gray list storehouse, realizes the renewal in gray list storehouse.Back-end server is to regarding as harmful exhaling
After crying the instruction except being intercepted to front-end server, the blacklist storehouse that blacklist is issued to front end also can be generated simultaneously, realized
The renewal in blacklist storehouse.
Use signaling re-injection mode during harmful Call Intercept, headend equipment according to blacklist matching result and after
End server transmitting order to lower levels, generates the signaling bag of call release, and harmful calling is implemented to intercept.It is related that signaling re-injection is construction
Message related to calls, the message is sent to network, you can realize to be harmful to calling interception.Wherein, the construction of signaling re-injection message
Completed by headend equipment.
The present invention uses different re-injection signalings for heterogeneous networks.
Called before intercepting call according to blacklist, specific re-injection signaling is as shown in the table：
| Control signaling | Control is carried | Media bearer | Re-injection signaling catching is controlled |
| SIP | IP | IP | Send the message of SIP 486 |
| BICC | IP | IP | Send BICC REL message |
| ISUP | TDM SS7 | TDM | Send ISUP REL message |
Called after intercepting call according to gray list, specific re-injection signaling is as shown in the table：
| Control signaling | Control is carried | Media bearer | Re-injection signaling catching is controlled |
| SIP | IP | IP | Send SIP BYE message |
| BICC | IP | IP | Send BICC REL message |
| ISUP | TDM SS7 | TDM | Send ISUP REL message |
Three kinds of signaling transfer protocols are simply introduced below.
SIP (Session Initiation Protocol) is a signaling control protocol for application layer.For creating,
Change and discharge the session of one or more participants.
SIP, using UDP (UDP) and transmission control protocol (TCP), will be independent of independently of transport layer
Couple together to the user flexibility of underlying infrastructure.
SIP BYE message is used to terminate the session set up, can by calling party or callee send this message come
Terminate session.
BICC is the abbreviation of Bearer Independent Call Control protocol, i.e., unrelated with carrying to exhale
It is control protocol.BICC is a call control protocol based on ISUP (ISDN User Part).Since being Call- Control1 association
View, BICC is only responsible for setting up, changes and terminating call.BICC is an agreement unrelated with carrying.REL is that the release of BICC disappears
Breath；REL is also the release message of ISUP.
The present invention realizes the interception to being harmful to calling by signaling re-injection mode, and specific implementation is in soft switch office
Existing network link is used and bypasses and connect pattern implementation signaling, acquisition of media.Headend equipment will converse bill report to back-end server,
Back-end server generates blacklist and gray list according to outside input, Signaling characteristics and behavioural characteristic etc..Headend equipment is to grey name
Singly realize that signaling is reported with media information, back-end server is judged the information for uploading, if it is determined that for harmful calling then to
Headend equipment sends interception order.Headend equipment realizes the interception to being harmful to calling by way of signaling re-injection.
Method of the present invention on the basis of other network normal talkings in not influenceing existing network, without being carried out to existing network
Larger transformation, you can realize the effective interception to being harmful to calling.
It is worth noting that, the foregoing is only presently preferred embodiments of the present invention, patent of the invention is not thereby limited
Protection domain, the present invention can also carry out the improvement of material and structure to the construction of above-mentioned various parts, or use skill
Art equivalent is replaced.Therefore all equivalent structure changes made with specification of the invention and diagramatic content, or directly or
Apply to other correlative technology fields indirectly to be similarly all contained in the range of of the invention covering.
