Description

解决通信系统欠费欺诈的方法及系统技术领域本发明涉及通信技术领域,尤其涉及解决欠费欺诈的方法及系统。 Means for Solving the communication system fraud and arrears TECHNICAL FIELD The present invention relates to communications technologies, and in particular relates to a method and system for solving arrears fraud. 背景技术在目前通信网络中,各电信运营商都大力开展各种增值业务,其中提供了众多的信息台服务,即手机或固定电话用户通过拨打某个特定的信息台电话号码,获得相应的信息服务,与此同时,该用户需要支付相应的信息服务费, 一般通过话费的方式收取,该费用往往比普通的通话费用贵。 BACKGROUND In current communication networks, telecom operators have vigorously carry out a variety of value-added services, which offer numerous information desk services, namely mobile or landline phone users by dialing a specific telephone number information table to obtain the corresponding information service At the same time, the user is required to pay the appropriate information service fee, usually charged by way of calls, the costs are often more expensive than the average cost of the call. 另一方面,目前用户成为运营商的签约客户后,根据运营商采用的技术不同,将用户分为实时控制预付费用户、非实时控制的预付费用户、非实时的后付费用户等。 On the other hand, the current user become the operator of the contract customers, depending on the technology used by operators, users into real-time control of prepaid subscribers, prepaid non-real-time control of users, non-real-time post-paid users. 对于实时控制预付费用户,系统根据其实际预存在运营商的帐户上的费用,计算出其可通话的时长,并根据该时长进行监控,不允许其透支费用;对于非实时控制的预付费用户,尽管用户已经在运营商预存了费用,但是通信系统仍然是在通话结束后才艮据呼叫通话记录,即话单,进行计费和从帐户扣费;而非实时的后付费用户,运营商可以预先给定一定的信用额度,该用户无需在运营商预存费用,在通话结束后运营商根据呼叫通话记录进行计费,到一定周期后再向用户统一收取费用。 For real-time control of prepaid subscribers, the system according to their actual stored on the carrier's account of the cost, calculated the length of which can call, and monitored in accordance with the length of time, does not allow its overdraft fees; for pre-non-real-time control of subscribers , although the user has been stored in the operator's expense, but the communication system is still at the end of the call after call, according to phone records Burgundy, that bill, billing and chargeback from your account; instead of real-time postpaid users, operators provides a given line of credit, the user need not stored in the operator's expense, according to operator billing call call records at the end of the call, to a certain period and then collect fees from the users. 对于所述非实时控制的预付费用户和非实时的后付费用户,由于从交换机形成话单到最终传到计费系统进行计费和从帐户扣费,有一段时间的延迟,无法在用户帐户余额为o时马上停止用户拨打电话的权限,导致用户在这段时间内可以透支费用。 For the pre-paid users and non-real-time control of the non-real time post-paid users, since it is formed from a single switch passed to the final charging system performs charging and deduction from the account, there is a period of delay, the user account can not be stop immediately when the user dials the phone balance o permission, causing the user during this time can overdraft fees. 由于上述缺陷用户可能采用如下方式进行欠费#1诈:用户先在运营商B 申请开通信息台并获得一个或多个号码,利用运营商A的手机或固定电话拨打其信息台号码。 Because of the above drawbacks may be employed as user # 1 fraud arrears manner: the operator B to user subscription to obtain one or more sets of numbers and by using mobile or landline operator A dials the station number information. 由于该手机或固定电话余额很少,很快就会透支,最终运营商A无法追回透支的费用;而另一方面运营商A仍需通过运营商B把信息费结算给信息台,导致运营商A的损失。 Since the mobile or landline little balance, will soon be overdrawn, the final operator A can not recover the cost of overdrafts; on the other hand still by operator A operator B to the information fee billing information desk, leading operators a loss of business. 另外,目前的通信系统处理过程如下所述:欺诈者拨打信息台电话时, 交换机,如移动交换中心MSC在呼叫结束后,产生一张呼叫话单,记录了主叫号码、被叫号码、通话开始时间、通话时长等信息,话单采集系统定期从交换机把话单传递到计费系统,计费系统根据话单的信息计算该次通话的费用,并从用户的帐户进行扣费, 一旦发现透支,就会发送指令请求通信系统停止该用户拨打电话的权限。 Further, the current communication system of the process is as follows: when the information station fraudster dials the telephone switch, such as a mobile switching center MSC after the call, it generates a single call, the recorded calling number, called number, call start time, duration, and more call information, then a single collection system to periodically switch from the bill is transmitted to the billing system, the cost of that call charging system is calculated according to the CDR information, and deductions from the user's account, if it is found overdrawn, the communication system sends instruction request permission to stop the user dials the phone. 由于交换机是在通话结束后才产生话单,并且由于交换机在地理上较分散,会跨市甚至跨省,使该话单传递到计费系统需要的时间可能较长,欺诈者在这段时间内:保持尽量长时间的通话,或尽量同时发起多个呼叫,就可以透支尽可能多的金额,从而导致电信运营商更多的损失。 Because the switch is to produce a single word after the end of the call, and because the switch is more dispersed geographically, and even inter-provincial cross-market will enable the bill to pass the time billing system may require a longer, during which time the fraudster inside: Keep the conversation as long as possible, or try to initiate multiple calls at the same time, as much as you can overdraft amount, resulting in the loss of more telecom operators. 用户同时发起多个呼叫的技术包括如图1所示,在通信系统中,提供了用户a通过发起多个通话的方式来发起多个呼叫到信息台。 A plurality of users to simultaneously initiate calls art shown in FIG. 1 comprises, in a communication system, a user to initiate a call to a plurality of information units by way of a plurality of calls initiated. 比如利用三方通话服务,用户a可以同时发起两个呼叫到信息台。 For example, use three-way calling service, users can initiate a call to the two sets of information simultaneously. 还包括如图2所示,b用户先设置呼叫转移,在满足一定条件时系统自动把呼叫转移到信息台号码,然后使用多部电话拨打b用户的号码,通信系统会分别建立从a、 c、 d、 e等多个用户到信息台的通话,从而实现同时转接多个呼叫到信息台。 As shown further comprising a, b 2 a user to set the call forwarding, call transfer system automatically when certain conditions are met to the information table number, then use the phone to call multiple b subscriber's number, a communication will be created from a, c, respectively, , d, e and so call information to a plurality of user stations, thereby achieving a plurality of calls simultaneously to the information transfer station. 由于b用户的号码呼叫转移到信息台的费用需要结算给信息台,导致运营商损失。 As the number of users b calls to cost information station you'll be billed to the information desk, leading to the loss of operators. 针对上述缺陷,现有技术通过对其用户拨打电话时,尽量把话单文件尽快传递到计费系统,由计费系统尽快进行计费和扣减余额,以及缩短从发现用户欠费到停止用户拨打电话权限的时间间隔,从而减少损失。 For the above disadvantages, the prior art through its user calls, as far as possible as soon as the file delivery CDR to the billing system for billing and charging system as soon as possible by the balance deductions, and shortening the stop from the user finds that the user arrears call permission intervals, thereby reducing losses. 但是,该方案由于交换机以及文件传递过程中无法把拨打信息台电话和拨打普通个人电话区分出来,无法对恶意欠费用户拨打电话和正常用户拨打电话区分开来,只能对所有的通话都减少上述的时间间隔。 However, this solution because the switch and the file transfer process can not call the information desk phone and a personal phone call distinguish ordinary, normal users can not make calls and malicious arrears separate telephone users to dial area to only have reduced for all calls interval described above. 一方面相关系统的技术实现难度大,改造成本高;另一方面,由于现有系统的局限性,必须在通话结束后通过多级的传递到计费系统进行计费,并且在系统中停止用户拨打电话的权限也需要一段时间,从而无法从根本解决欠费欺诈的问题。 An aspect related systems is difficult to achieve, the high cost of the transformation; on the other hand, due to the limitations of existing systems, the charge must be passed through to a multi-stage charging system after the call ends, the user stops the system and permissions calls also take some time, making it impossible to solve the problem of arrears from the fundamental fraud. 发明内容本发明的目的在于提供解决通信系统欠费欺诈的方法及系统。 Object of the present invention to provide a method and system for a communication system to solve the arrears fraud. 本发明的目的是通过以下技术方案实现的: 一种解决通信系统欠费欺诈的系统,包括:业务控制点与账户系统相连,用于根据账户系统提供的信息,对拨打到特定被叫的呼叫进行鉴权及监控;触发号码存储及触发模块,设置于移动网络中的移动业务交换中心、关口移动业务交换中心或固定网络中的固定交换机中,用于保存可以触发到业务控制点的号码,将所述存储的号码对应的呼叫触发到业务控制点;所述业务控制点中设置有:实时通话监控模块,用于对需要监控的呼叫实施鉴权及监控,切断存在欠费的呼叫;所述业务控制点中还设置有下述任一个或多个模块:黑名单功能模块,用于存储拒绝拨打到特定被叫的号码;白名单功能模块,用于存储不启用监控和切断呼叫功能的主叫号码;

SCP首先获取当前正在通话的主叫号码,并由号码锁定模块检查该号码作为主叫是否已经发起了到信息台的呼叫,即判断号码锁定模块中是否存在该主叫号码发起所述呼叫的记录;如果已经发起了呼叫,则拒绝新请求的呼叫;如果是第一次呼叫,则号码锁定模块记录该主叫号码。 SCP first acquires the calling number is currently speaking, by the number of the locking module checks whether the calling number as a call has been initiated to the information table, that is, whether the calling number to initiate the call record number is present in the lock module ; If the call has been initiated, the new call request is rejected; if the first call, the number lock module records the calling number. 通过对主叫号码的"锁定"处理,使得某个号码只能同时发起一个到信息台的呼叫。 By calling number "lock" process so that only a certain number to initiate a call to the information desk at the same time. 对于前转号码同样可以实行号码锁定方式; Forwarding number for the same number of locking system may be practiced;

若主叫号码或前转号码没有被锁定,贝'JSCP判断是否本端设置有黑名单和/或白名单功能模块,若存在所述模块,则根椐呼叫的主叫号码/前转号码、或被叫号码与黑名单或白名单功能模块中存储的号码比较,若是黑名单中的号码,则拒绝该呼叫请求;若是白名单中的号码,则不进行任何限制。 If the forwarding number or the calling number is not locked, Tony 'JSCP determines whether the present end is provided with a blacklist and / or whitelist function module, if the module is present, the root noted in the calling number of the call / forwarding number, number or called number is compared with black or white list stored in the function module, if the number in the blacklist, the call request is rejected; if the number whitelist, not any limitation. 如果该号码不属于黑明名单及白名单,则对该呼叫实施鉴权及监控操作。 If the number does not belong to the black list and white list out, then the authentication and call monitoring operation embodiment.

SCP中的呼叫鉴权和监控可以采用以下几种方式之一实现: The SCP authentication and call monitoring can be achieved using one of the following ways:

1、 SCP与帐户系统没有用户信息、账户余额、及信用度等查询接口时,SCP直接授权用户进行通话。 1, SCP systems without user account information, account balances, and credit and other query interfaces, SCP directly authorized users make a call. 实时的产生话单,并把话单传递给计费系统,由计费系统根据话单文件对该次通话进行计费和从帐户扣费,若计费系统发现用户欠费,会请求通信系统内的鉴权系统,如HLR,取消该用户拨打电话的权限。 Generating real-time CDR and transmitting the CDR to a billing system, for the charging system according to the current call by the call detail record file from billing and account deduction, if the charging system finds that the user arrears, requests the communication system authentication system within, such as HLR, cancel the permission of the user to make calls.
