Description
Technical field
The present invention relates to the communication network technology, relate in particular to the method, system and device of restraining malice back-dialing card service.
Background technology
Along with the development of Communications Market, increasingly competitive between the different communication operator, individual communication operator uses irrational means to realize the malice competition, thereby has produced some special business.With an object lesson class particular service that exists is at present described below:
The B carrier network that is provided with this particular service comprises gateway exchange and clawback card server, and certain A provider customer has registered this particular service of B operator, and this business that B operator provides is a malice, makes A operator cause loss.This particular service is specially: when the B provider customer made a call, the gateway exchange of B carrier network transferred the call to the clawback card server of B carrier network the A provider customer, was sent the voice suggestion of on-hook to the A provider customer by the clawback card server; After the A provider customer on-hook, this A provider customer of the automatic clawback of this clawback card server and this B provider customer, both sides receive calls as called, realize conversation.Cost during conversation is deducted from the prepaid card that this A provider customer buys when B operator registers this particular service.
The prerequisite that such particular service is used is, do not collect telephone expenses when the A provider customer does called the conversation or pay lower telephone expenses because of the low price monthly payment, and the cost of collecting when conversing as caller is higher.Drive the A provider customer like this and use this type of particular service, utilize the difference of settling accounts between A carrier network and the B carrier network, do calledly with becoming as the A provider customer of caller originally, the telephone expenses that make former cause A operator collect change by B operator to be collected.Like this, telephone expenses that A operator can not be collected should collect or reduce charge have but increased the income of B operator.
This type of particular service title is different, is referred to as the malice callback card service herein.The malice callback card service also has following function: the A provider customer binds clawback card and phone number by dialing access code after buying back malice clawback card; Have the access code that can change, make A operator limit this malice callback card service according to called access code; Caller ID display is fixing during clawback, makes the A operator can't be by this malice callback card service of caller number restriction; When the A provider customer called out certain user by the clawback card, the caller identification that the called subscriber sees can be the true number of user, also can be virtual-number.
Here, the A carrier network in the malice callback card service is called the network of suffering a loss, the B carrier network is called provides the callback card service network.Malice callback card service system relates generally to provides the callback card service network and the network of suffering a loss, and the network of suffering a loss mainly comprises local terminal end office (EO) and local terminal gateway exchange, provides the callback card service network mainly to comprise clawback card server and opposite end gateway exchange.Local terminal networking and the callback card service network is provided may be the arbitrary network of different operators, for example, the network and provide the callback card service network can be fixed network, mobile network, communication network, UNICOM's network or the like of suffering a loss.Be the mobile network with the network of suffering a loss below, it is that fixed network is an example that the callback card service network is provided, and malice callback service system and malice callback service are further detailed.
Referring to Fig. 1, structural representation for malice callback card service system, this system comprises mobile network and fixed network, the mobile network comprises the visit ground (VMSC of mobile switching centre, Visited MSC) and (GMSC of mobile gateway office, Gateway MSC), fixed network comprises fixed network gateway exchange and clawback card server.VMSC is also referred to as mobile end office (EO).In the different operators network, mobile end office (EO), mobile gateway office are respectively end office (EO), the gateway exchange of respective operator network, and the fixed network gateway exchange is the gateway exchange of respective operator network.Typical malice callback card service is used binding procedure and the placement process when comprising registration, corresponding to the described malice callback card service of Fig. 1 system, binding procedure is a flow process shown in Figure 2, and placement process is Fig. 3 and the described flow process of Fig. 4, describes respectively below in conjunction with accompanying drawing.
Referring to Fig. 2, be the binding flow chart of malice callback card service, this binding flow process may further comprise the steps:
In this step, described mobile subscriber initiates the calling of callback card service can go into the number realization by the clamping of input clawback, the true access code that number may be the clawback card server is gone in the clawback clamping, but in order to prevent that mobile operator from closing envelope to the true access code of clawback card server, the true access code that number generally is not the clawback card server is gone in the clawback clamping, but effective mobile subscriber number or fixed-line subscriber number, this mobile subscriber number or fixed-line subscriber number are transferred on the clawback card server by the mode of signatory Call Forwarding Unconditional.The calling that described mobile subscriber initiates callback card service also can realize by input clawback card virtual-number, this clawback card virtual-number is also referred to as the one number service number, with the phone number binding of registration, a clawback card virtual-number may have been hidden the true access code of a plurality of clawback card servers.
In this step, the clawback card server sends ACM to mobile end office (EO), confirms that this calling sets up.The mobile subscriber that described alerting message is accused in the mode of ring-back tone.
Step 203, the clawback card server provides the interactive voice with the mobile subscriber, after the mobile subscriber selects the numerical key corresponding with input clawback card number of the account and clawback clip pin according to voice suggestion, behind button input clawback card number of the account and the clawback clip pin, mobile end office (EO) is sent to the clawback card server by signaling or signal tone with user key-press information.
Mobile end office (EO) is dual-tone multifrequency (DTMF by the user key-press information that signaling or signal tone are sent to the clawback card server, Dual Tone Multiple Frequency) signaling or signal tone can be learnt the DTMF number that the mobile subscriber imports by dtmf signaling or signal tone.For example, during as if input clawback card number of the account or clawback clip pin, button 6 times, then the DTMF number is 6.Ordinary circumstance, the DTMF number of clawback card number of the account or clawback clip pin is greater than 6.
Mobile subscriber's button once, just and mobile end office (EO) carry out the mutual of several message, comprise initial DTMF message (start DTMF), confirm initial DTMF message (start DTMF ack), stop DTMF message (stop DTMF) and affirmation stops DTMF message (stop DTMF ack).
After step 204, clawback card server received dtmf signaling or signal tone, binding was finished, and moved end office (EO) through fixed network gateway exchange and mobile gateway office direction and sent release message (REL, RELease), mobile end office (EO) discharges the calling with the mobile subscriber.
In the binding flow process of above-mentioned Fig. 2, also may may further comprise the steps between the step 202 and 203 or between step 203 and 204: the clawback card server is through fixed network gateway exchange and mobile gateway office, (ANM, Answer message) sends to mobile end office (EO) with response message.
Comprehensive aforementioned binding flow process as can be seen, the mobile subscriber imports DTMF may provide the callback card service network after the network of suffering a loss sends the step of ACM, also may provide the callback card service network after the network of suffering a loss sends the step of ANM.Certainly, in different malice callback card services, the mobile subscriber imports DTMF also may provide the callback card service network after the step of other message that the network of suffering a loss sends.The step that the mobile subscriber imports DTMF in this binding flow process is providing the callback card service network after the network of suffering a loss sends ACM or ANM, and this moment, the mobile subscriber was as caller, and DTMF that herein will input this moment is called caller DTMF.
Referring to Fig. 3, be the call flow legend one of malice callback card service, this flow process may further comprise the steps:
In this step, described mobile subscriber initiates the calling of callback card service can go into the number realization by the clamping of input clawback, also can realize by input clawback card virtual-number.The number that has also comprised the mobile subscriber among the described IAM.In this prior art scheme, the number of supposing the mobile subscriber is A, and the fixed number that the mobile subscriber calls out is B.
In this step, the clawback card server sends ACM to mobile end office (EO), confirms that this calling sets up.The mobile subscriber that described alerting message is accused in the mode of ring-back tone.
Mobile end office (EO) is dtmf signaling or signal tone by the user key-press information that signaling or signal tone are sent to the clawback card server, can learn the DTMF number that the mobile subscriber imports by dtmf signaling or signal tone.For example, the fixed number B of input is 0826-3333222, button 11 times, and then the DTMF number is 11.Ordinary circumstance, the DTMF number of input telephone number is greater than 6.
Step 305, the clawback card server is set up calling as called with the mobile subscriber with mobile subscriber's number A, be specially: the clawback card server moves the transmission IAM of end office (EO) through fixed network gateway exchange and mobile gateway office direction, and mobile end office (EO) sends ACM and ANM through mobile gateway office and fixed network gateway exchange to the clawback card server again.
In the call flow of above-mentioned Fig. 3, also may may further comprise the steps between the step 302 and 303 or between 303 and 304: the clawback card server sends to mobile end office (EO) through fixed network gateway exchange and mobile gateway office with ANM.
Comprehensive aforementioned call flow as can be seen, the step that the mobile subscriber imports DTMF may provide the callback card service network after the network of suffering a loss sends the step of ACM, also may provide the callback card service network after the network of suffering a loss sends the step of ANM.Certainly, in different malice callback card services, the mobile subscriber imports DTMF also may provide the callback card service network after the step of other message that the network of suffering a loss sends.The step that the mobile subscriber imports DTMF in this flow process is providing the callback card service network after the network of suffering a loss sends ACM, and this moment, the mobile subscriber was as caller, and DTMF that herein will input this moment is called caller DTMF.
Referring to Fig. 4, be the call flow legend two of malice callback card service, this flow process may further comprise the steps:
In this step, described mobile subscriber initiates the calling of callback card service can go into the number realization by the clamping of input clawback, also can realize by input clawback card virtual-number.The number that has also comprised the mobile subscriber among the described IAM.In this prior art scheme, the number of supposing the mobile subscriber is A, and the fixed number that the mobile subscriber calls out is B.
Step 404, the clawback card server is set up calling as called with the mobile subscriber with mobile subscriber's number A, be specially: the clawback card server moves the transmission IAM of end office (EO) through fixed network gateway exchange and mobile gateway office direction, and mobile end office (EO) sends ACM and ANM through mobile gateway office and fixed network gateway exchange to the clawback card server again.
In this step, mobile terminal office direction clawback card server sends ACM and ANM, confirms that this calling sets up.ACM and ANM message for confirming that this calling has been set up.
Step 405, the clawback card server provides the interactive voice with the mobile subscriber, requires the mobile subscriber to import fixed number B, and behind mobile subscriber's button input fixed number B, mobile end office (EO) is sent to the clawback card server by signaling or signal tone with user key-press information.
Mobile end office (EO) is dtmf signaling or signal tone by the user key-press information that signaling or signal tone are sent to the clawback card server, can learn the DTMF number that the mobile subscriber imports by dtmf signaling or signal tone.
Step 406, the clawback card server fixed number B that continues, and mobile number A is connected with fixed number B, make it normal talking.
From the call flow of this prior art scheme as can be seen, the mobile subscriber to import DTMF may be after office direction opposite end, mobile terminal end office (EO) sends ANM.Certainly, in different callback card services, the mobile subscriber imports DTMF also may the mobile terminal after the step of other message of sending of office direction opposite end end office (EO).The step that the mobile subscriber imports DTMF in this flow process is providing the callback card service network after the network of suffering a loss sends ACM, and this moment, the mobile subscriber was as called, and DTMF that herein will input this moment is called called DTMF.
Fig. 1,2,3 and 4 is to be fixed network so that the callback card service network to be provided, the binding and the placement flow of malice callback card service when the network of suffering a loss is the mobile network, for the malice callback card service between any operator, the similar binding and the placement flow that all exist exemplify here no longer one by one.
For the restraining malice back-dialing business, prior art adopts the signaling catching analysis, is the mobile network with the network of suffering a loss equally, and it is that fixed network is an example that the callback card service network is provided, and is described.Existing signaling catching analytical technology makes a call the mobile subscriber, after the clawback card server sends release of REL message and mobile subscriber's calling, just after step 304 or the step 403, removes the calling that callback card service network clawback mobile subscriber is provided.This signaling catching technology is specially: connect the signalling analysis instrument at the local terminal gateway exchange, extract mobile subscriber's the number A and the number B of fixed-line subscriber by this signalling analysis instrument, judge, if in a period of time after clawback card server transmission REL message release and mobile subscriber's the calling (being traditionally arranged to be for 5 seconds), this mobile subscriber has calling from this fixed network as the called subscriber, and from the calling number of this fixed network incoming call is the called number B that this mobile subscriber dials, then be judged as the malice callback card service, this calling of mandatory dismantling is to limit this malice callback card service.
There is following shortcoming in the technology of existing restraining malice back-dialing business: because to carry out interactive signaling very many with the local terminal gateway exchange, cause the signaling catching Analysis of Complex, signalling analysis instrument cost is very high; The signalling analysis instrument is difficult to direct dismantling call, and the network of need suffering a loss is done special support and just can be finished; Judge whether to be the unusual difficulty of malice callback card service according to calling number from fixed network incoming call, because clawback mobile subscriber's calling number generally can change or change in the clawback flow process of malice callback card service, the true number B that dials of mobile subscriber not necessarily; Judge whether to be the malice callback card service according to calling number from the fixed network incoming call, may be malice callback card service and with some regular traffic false judgment with its mandatory dismantling, thereby cause the traffic call completing rate to descend, influence network index and user's impression of operator.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Referring to Fig. 5, be the exemplary process diagram of the method for embodiment of the invention restraining malice back-dialing card service, this method may further comprise the steps:
The embodiment of the invention with in the malice callback card service through the network of suffering a loss to providing before the callback card service network sends dtmf signaling or signal tone, what the network of suffering a loss received sends to the message about successfully set up calling out that the callback card service network is provided by the network of suffering a loss, and the network of suffering a loss receive by provide the callback card service network to send to suffer a loss network about successfully setting up the message of calling out, be referred to as the message of confirming call setup.This message is to suffer a loss network to providing the callback card service network to send the prerequisite of dtmf signaling or signal tone.Just, after the network of suffering a loss received the message of this affirmation call setup, the user is imported dtmf signaling to the network of will suffering a loss or signal tone sends the step that the callback card service network is provided to.
In same call, the user both sides that call out remain unchanged, and, send to dtmf signaling that the callback card service network is provided or the message of signal tone and affirmation call setup is corresponding relation through the network of suffering a loss.Such as, among Fig. 2 or Fig. 3 is the message of confirming call setup by ACM that provides the callback card service network to send to suffer a loss network or ANM, this ACM or ANM and to send to dtmf signaling or signal tone that the callback card service network is provided through the network of suffering a loss be corresponding relation; Sending to the ANM that the callback card service network is provided by the network of suffering a loss among Fig. 4 also is the message of confirming call setup, and this ANM is a corresponding relation with sending to dtmf signaling or signal tone that the callback card service network is provided through the network of suffering a loss.
The network of suffering a loss described in this step will send to dtmf signaling or signal tone that the callback card service network is provided through the network of suffering a loss and block, comprise any method of blocking described dtmf signaling or signal tone, for example, abandon described dtmf signaling or signal tone, or to the dtmf signaling or the signal tone that provide the callback card service network to send a mistake, or the like.
The network of suffering a loss that the malice callback card service relates to may be the arbitrary network of different operators with the callback card service network is provided, for example, suffer a loss network and provide the callback card service network can be fixed network, mobile network, communication network, UNICOM's network or the like.Be the mobile network with the network of suffering a loss below, it is that fixed network is an example that the callback card service network is provided, and the scheme of the embodiment of the invention is described.
When the message of the described affirmation call setup of step 501 comprised that described clawback card server sends to the ACM of the network of suffering a loss or ANM, step 502 is described, and to send to dtmf signaling or signal tone that the callback card service network is provided be caller dtmf signaling or signal tone.The malice callback card service of this situation is corresponding to the binding flow process of Fig. 2 and the call flow of Fig. 3, the mobile subscriber imports DTMF may provide the callback card service network after the network of suffering a loss sends the step of ACM, also may provide the callback card service network after the network of suffering a loss sends the step of ANM.Certainly, in different malice callback card services, the mobile subscriber imports DTMF also may provide the callback card service network after the step of other message that the network of suffering a loss sends, and described other message also is the message of the alleged affirmation call setup of present embodiment.Providing callback card service network mobile subscriber after the network of suffering a loss sends ACM or ANM to import DTMF, the mobile subscriber is as caller, and this moment, the DTMF of input was called caller DTMF.Dtmf signaling or the signal tone of this moment comprise clawback card number of the account, clawback clip pin, clawback card virtual-number or call number.
When the message of the described affirmation call setup of step 501 comprised that the network of suffering a loss sends to the ANM of described clawback card server, step 502 is described, and to send to dtmf signaling or signal tone that the callback card service network is provided be called dtmf signaling or signal tone.The malice callback card service of this situation is corresponding to the call flow of Fig. 4, and it may be after office direction opposite end, mobile terminal end office (EO) sends ANM that the mobile subscriber imports DTMF.Certainly, in different callback card services, the mobile subscriber imports DTMF also may the mobile terminal after the step of other message of sending of office direction opposite end end office (EO), and described other message also is the message of the alleged affirmation call setup of present embodiment.Providing callback card service network mobile subscriber after the network of suffering a loss sends ACM to import DTMF, the mobile subscriber is as called, and this moment, the DTMF of input was called called DTMF.Dtmf signaling or the signal tone of this moment comprise call number.
In the practice, remove other business of malice callback card service, after receiving ACM before the ANM, the step that also has input DTMF, but this moment is less by the DTMF number of button input, and the DTMF number of importing in the malice callback card service flow process is generally big than the DTMF number of importing in described other business.Therefore, the embodiment of the invention also provides a kind of method by judging that the DTMF number limits the malice callback card service.
At this moment, step 502 is: the network of suffering a loss is judged and is sent to the DTMF number that dtmf signaling that the callback card service network is provided or signal tone comprise through the network of suffering a loss and allow number greater than the DTMF that sets in advance, and then described dtmf signaling or signal tone is blocked.Send to the DTMF number that dtmf signaling that the callback card service network is provided or signal tone comprise through the network of suffering a loss and allow number if judge, then give the callback card service server that the callback card service network is provided the DTMF normal transmission less than the DTMF that sets in advance; Send to the DTMF that DTMF number that dtmf signaling that the callback card service network is provided or signal tone comprise equals to set in advance through the network of suffering a loss and allow number if judge, can block described dtmf signaling or signal tone, also can dtmf signaling or signal tone not blocked.For example, the DTMF number of importing in the malice callback card service is generally greater than 6, can allow number to be set to 6 by DTMF, send to DTMF number that dtmf signaling that the callback card service network is provided or signal tone comprise greater than 6 the time when judging, then will block this dtmf signaling or signal tone through the network of suffering a loss.
When adopting the method for judging the DTMF number that the malice callback card service is limited, occur unusual for fear of user terminal, in the process that described dtmf signaling or signal tone are blocked, stopDTMF ack message and stop DTMF ack message can be replied to user terminal by normal condition.
At other regular traffics except that the malice callback card service in the practice, as business such as telephone bank, fixed network IP phonecards, also may after receiving ANM, import the situation of DTMF, the present invention also provides a kind of method that the malice callback card service is limited.During for described other regular traffics, its flow process and malice callback card service are similar, different is: when the user initiates described other regular traffics by the input access code in step 201, step 301 or step 401, its access code is the access code of described other regular traffics, rather than the access code of malice callback card service, as, the access code of telephone banking is the number of 9 beginnings, the access code of network IP CARD is 17, or the like.At this moment, send to the information that has comprised access code that should business among the IAM that the callback card service network is provided by the network of suffering a loss.In different agreements, described IAM is different corresponding message, and the application is with its unified initial address message of equal value that is called.
For fear of restriction to this class regular traffic, the method of a kind of restraining malice back-dialing card service provided by the invention had been added following steps before step 501: the network of suffering a loss is judged by the network transmission of suffering a loss provides whether the number that comprises in the initial address message of equal value of callback card service network is reasonable number, if, process ends then; Otherwise, execution in step 501.The number that comprises in the described initial address message of equal value comprises the number by user's input such as access code.
Described judge the number that comprises in the initial address message of equal value whether be reasonable number can method be: judge whether the prefix that comprises in the initial address equivalence message is reasonable numeral, if then be judged as reasonable number; Otherwise, be not reasonable number.Described reasonable numeral can be set according to the situation of practical business.Such as, the bank service number is generally the number of 9 beginnings, and then prefix 9 is rationally digital; For another example, the access code of IP phonecard is generally with 17 beginnings, and then prefix 17 is rationally digital, or the like.
The method of the embodiment of the invention can realize in the network of suffering a loss by software mode.Step 502 is described will to send to dtmf signaling or signal tone that the callback card service network is provided through the network of suffering a loss and block, realize any position that can transmit described dtmf signaling or signal tone in the network of suffering a loss, for example, can realize in end office (EO) in the network of suffering a loss or gateway exchange, when being provided with tandem office between end office (EO) if suffer a loss in the network and the gateway exchange, also can in tandem office, realize, or the like.And, describedly will send to the signaling plane that the dtmf signaling that the callback card service network is provided blocks in the network of suffering a loss through the network of suffering a loss and realize, describedly will send to the loading end that provides the dtmf signal of callback card service network sound to block in the network of suffering a loss through the network of suffering a loss and realize.
Referring to Fig. 6, be the system configuration schematic diagram of embodiment of the invention restraining malice back-dialing card service, this system comprises the network of suffering a loss.
