Detailed ways

Features and exemplary embodiments of various aspects of the invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention. The present invention is by no means limited to any specific configurations and algorithms presented below, but covers any modification, substitution and improvement of elements, components and algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the present invention.

An embodiment of the present invention provides a call processing method. Fig. 1 is the flow chart of the call processing method according to the embodiment of the present invention, as shown in Fig. 1, this process comprises the following steps: step S102, obtain the telephone number of the calling party of calling; Step S104, obtain the telephone number of the calling party The historical call behavior data of the number; Step S106, judge whether the calling user is an abnormal user according to the historical calling behavior data; Step S108, when the calling user is an abnormal user, terminate the call; , continue calling.

Through the above steps, the judgment is made according to the historical behavior of the calling user, so that it is easier to distinguish abnormal users, and if they are abnormal users, their calls are blocked, thus solving the problem that the prior art cannot prevent harassment to users in advance If there is a problem, it can block the call in time, and prevent phone harassment more effectively.

As an optional implementation, in order to be more secure, an authentication link can also be added to the calling number, that is, the calling user's phone number is authenticated, and if the authentication fails, the call is terminated; If the authorization is passed, obtain the historical call behavior data of the calling user's phone number. By adding an authentication link, illegal users can be better identified.

There are many ways of authentication, for example, blacklist and whitelist can be used. Determine whether the calling user's phone number belongs to the white list or black list; if the calling user's phone number is in the black list or not in the white list, the authentication fails; if the calling user's phone number is in the white list or not In the blacklist, the authentication passes.

As an optional implementation, three indicators are selected to compare whether the calling user is an abnormal user: call frequency offset value, calling average call duration, and hang-up ratio. Each or any combination of these three indicators can be used to determine whether the user is an abnormal user.

The following uses an example to illustrate how to obtain the call frequency offset value, the proportion of hangups, etc.

As an optional implementation manner, obtaining the calling frequency offset value of the calling user's phone number includes: acquiring the average calling frequency of other users, and obtaining the calling frequency offset value according to the calling frequency and the average calling frequency of the calling phone number; and /or, obtaining the hang-up ratio of the calling user's phone number includes: obtaining the number of calling calls of the calling number, or all calls of the calling number; obtaining the number of times the calling number was hung up during the calling call ; Obtain the proportion of hung up according to the number of times of being hung up, the number of calling calls and the number of all calls.

If multiple indicators are used, this can be judged using a weighted sum.

For example, according to the call frequency offset value, the caller's average call duration and/or the proportion of the called hangup, the corresponding feature value and weight value are obtained respectively; Carry out weighted summation with the weight value to obtain the abnormal index of the calling user's phone number; compare the abnormal index of the calling user's phone number with the abnormal index range of the confirmed abnormal user; when the calling user When the abnormal index of is within the abnormal index range of the verified abnormal user, it is determined that the calling user is an abnormal user.

As an optional implementation manner, user privacy can also be guaranteed from another aspect. In this optional embodiment, the phone number filled in by the user on the predetermined website is received; the authorization of the user to use the phone number on the predetermined website is obtained; a temporary number corresponding to the user's phone number is generated, wherein the temporary number is used to Used when calling to hide the user's phone number. Through this optional implementation, a virtual number can be set, and the mapping relationship with the real number can be recorded, so as to achieve the purpose of privacy protection.

As an optional implementation manner, a life value may also be assigned to the temporary number, and the life value is used to indicate the validity time of the temporary number. More preferably, the life value can also be adjusted, for example, the life value is adjusted upon receiving a trigger of a predetermined event, wherein the adjustment includes increasing or decreasing the life value.

The following describes an optional embodiment. In this optional embodiment, a call processing system and method are provided to protect user privacy from two aspects of personal point-to-point call service and business call flow. Among them, the call control subsystem performs real-time authentication on the user number for the point-to-point communication call service of individual users through multi-dimensional characteristic values. Carry out traffic blocking by expressing suspected harassment or fraudulent calls to achieve the purpose of preventing phone harassment; the number authorization subsystem is aimed at the process of website merchants, and transforms the user's behavior of filling in the mobile phone number into the user's credit granting behavior for this merchant or website . Open the user number authorization capability to external merchants through the capability open platform. When external merchants need to contact users, they can query the user's temporary phone number through the merchant, contact the user, and control the life value of the temporary number, so as to prevent phone number purpose of disclosure.

FIG. 2 is a schematic diagram showing a call processing system, which mainly protects user privacy during a telephone call process. For the point-to-point communication call service of individual users, the call control subsystem is used to prevent phone harassment; for the business call process, the number authorization system is used to prevent the user's phone number from leaking.

call control subsystem

Since the business support system in the telecommunications field stores more comprehensive, deeper, and more private customer data, this embodiment establishes a call control subsystem in the communication support system to address this problem. As shown in Figure 3, when the user initiates a call request, when the user initiates a call, SSP (Service Switch Point, service switching point) sends SCP (Service Control Point, service control point) according to CSI (CAMELSubscription Information, CAMEL subscription information) ) triggers the intelligent process, and the SCP initiates an application duration request to BOSS (Business Operation Supporting System, business operation support system). Before the BOSS returns the fragmented call duration to the SCP, the call judgment link is added. The call control subsystem and the BOSS complete the interaction through real-time messages. The BOSS initiates a call judgment request to the call control subsystem, and the call control subsystem authenticates the current calling number. The call control subsystem judges whether to let the user through. The call control subsystem judges whether the status of the current calling user is normal, and returns the authentication result to the BOSS, and the BOSS performs subsequent call procedures such as balance distribution according to the returned result. If it is judged that the calling user is a normal user, then continue to complete the follow-up process, such as fragmentation, ringing, billing, etc.; if it is judged that the calling user is an abnormal user, then stop the connection process, and the called user has no perception To achieve the purpose of anti-harassment.

Among them, the call control subsystem judges whether the status of the calling user is normal or not in real time through multi-dimensional feature values, using three feature values: the call frequency deviation value, the average call duration of the caller, and the proportion of hang-ups.

By analyzing the statistical results of traffic analysis of suspected harassing or fraudulent calls, since the suspected harassing calls need to initiate multiple calls, most of the suspected harassing calls have a relatively high call frequency, and the deviation value of the user's calling frequency is used as the criterion for judging the suspected harassing calls One of the characteristic values; and the call time of the called user for this type of phone is generally short and the called user often hangs up the phone actively, in many cases it hangs up in a very short time after the call is connected, and the average call duration of the caller is and the proportion of hang-ups are used as the characteristic values of suspected fraudulent or harassing calls.

The call control authentication process will be described in detail below in conjunction with the operation flow chart of the call control subsystem shown in FIG. 4 .

Step 1, the user initiates a call request on the communication network side;

Step 2, the request signaling is authenticated through the call control subsystem;

Step 3, judging whether the calling number is a whitelist user;

Step 3-1, if the calling number is a whitelist user, establish a call and skip to step 5;

Step 3-2, the calling number is not a whitelist user, proceed to step 4;

Step 4, judge whether the number is a normal number through the multidimensional feature value;

In this embodiment, combined with the user data of the service support system, a three-dimensional characteristic value is formed from the three aspects of the call frequency deviation value, the average call duration of the caller, and the proportion of the hang-up, and the three-dimensional characteristic value is used to judge whether the calling user is in a normal state in real time.

Among them, the user call frequency deviation value is:

Among them, num is the user number, t is the time of this call, Cf(num,t) is the calling frequency calculated in real time for this user number, and the calling frequency can be defined as the number of calls per unit time, for example, from the initial time to t time Record the number of calls initiated by this number, It is the average call frequency of n users sampled statistically at time t, and the Ca value may vary greatly in different time periods, for example, the average call frequency will increase during the Spring Festival. The call time and times can be obtained through the existing data of the support system.

The expression of the caller's average call duration is:

Among them, Cavg(num,t _i ,t _j ) is the average call duration of caller num from the call at time t _i to the call at time t _j of phone num, and CTO(num,t) indicates that when a call is initiated at time t, the call The duration of the call. The duration of each call is stored in the call cloud list, which can be simply calculated after statistics to obtain the data used in the formula.

The formula for the proportion of being hung up is:

Among them, Ob(num, t) is the number of calling calls of phone num within t time, and Gt(num, t) is the total number of calls of phone num within t time. The call ID and number of calls that were hung up are saved in the call cloud list of the business support system.

According to the three-dimensional eigenvalues, the calling user is suspected of harassment or fraud call index as follows:

Among them, Eig(i) is different eigenvalues, and Wei(i) is the weight value corresponding to different eigenvalues. For the suspected harassing or fraudulent call index set that has been confirmed as fraudulent or harassing calls, U={u1,u2,...,um}, for any

S(n)∈[Min(U _i ),Max(U _j )](1≤i≤m,1≤j≤m) (Formula 5)

That is, it is judged that the call is a suspected harassment or fraud call.

Step 4-1, determine that the user number is not a suspected harassing or fraudulent call, and proceed to step 5;

Step 4-2, determine that the user number is a suspected harassing or fraudulent call, and proceed to step 6;

Step 5, the call control system passes the authentication, proceeds to establish a call process, and updates the relevant data of this number in the authentication system;

Step 6, the call control system fails the authentication, terminates the calling request, and records the behavior log.

Number Authorization Subsystem

In some scenarios, the mobile phone number, as the main contact method to contact the user, is mandatory to fill in the order or user information of some merchants or websites (for example, the user's phone number in the Taobao order is used as the contact method for the delivery notification) . This inevitably leaks the user's mobile phone number to a third-party merchant, and the telecom operator cannot control the subsequent user's private number. In response to such problems, by establishing a number authorization subsystem, the user's behavior of filling in the phone number is transformed into the user's credit authorization behavior for this merchant or website. The user number authorization capability is developed to external merchants through the capability open platform. If an external merchant needs to contact a user, it can query the user's temporary phone number through the merchant and contact the user. In this process, the merchant cannot obtain the real number of the user. Even if the harassing or fraudulent calls contact the user in this way, the log can be checked in the number authorization subsystem to find out that the merchant is the source of the number leakage, so as to prevent the leakage of the phone number. Purpose.

Fig. 5 is an illustration of the operation flow of the number authorization subsystem according to the embodiment of the present invention. Referring to Fig. 6 and Fig. 7, a detailed description will be given in conjunction with the user's credit granting process to the merchant and the process of initiating a call by relevant personnel of the merchant.

The user logs in to the merchant's page, and needs to grant credit to the merchant in order and other links;

The merchant system calls the number authorization subsystem in the operator system to complete the user's communication credit to the merchant, and the operator number authorization subsystem records the credit;

The user calls the number authorization subsystem through the merchant system. For example, when the user logs in to Taobao and generates order user information, the user needs to authorize the number of Taobao. In this link, the Taobao system and the number authorization subsystem of the operator complete the message interaction through interface calls. Complete credit. It can be imagined that on the order page, there is a button showing authorization, and after clicking it, it jumps to the operator system authorization page. After the user enters the operator's user password, authorization verification is performed (similar to the meaning of jumping to Alipay payment), and then the page is called back On the Taobao order page, it shows that the number has been authorized.

Specifically, the number authorization subsystem includes an authorization center, a number query center, and a number generation scheduling container;

The merchant system initiates a query request to the number query center in the operator's number authorization subsystem through the service call method; the number query center initiates a credit query to the credit center, and if the credit center returns credit successfully, proceed to the next step; if the credit center returns If the credit granting fails, the query failure is returned to the merchant user number query system, and the end; the number generation scheduling container is triggered to generate the temporary user number requested this time, and synchronized to the billing domain and the core network domain, so that billing and calling can identify the number , proceed to the next step; return the temporary number to the merchant system through the number inquiry center, and contact the user through the temporary number.

If the credit is granted successfully, the merchant’s front page will call back the credit information and continue to complete the order; if the credit fails, the merchant’s front page will fail to call back the credit information, and the merchant cannot obtain the user’s communication information.

In actual situations, after the merchant personnel apply for the user's temporary number for the first time through the merchant system, they need to contact the user again under certain conditions. There is no need to apply for a new temporary number through the system again, which reduces repeated operations, reduces system load, and improves user experience. In the number generation scheduling container, the life cycle of the temporary number is managed, the life value of the temporary number is defined, and the change of the life value is triggered by certain events, such as the life value decreases with time, or the number of calls increases. When the life value is less than the threshold, the temporary number becomes invalid.

The expression that defines the health value is:

Among them, CustId is the code of the merchant in the system, t represents the survival time of the temporary number, num is the mobile phone number, the Init function represents the initial life value, and the function Comp represents the life cycle change value of the nth dimension of the temporary number at x time after the number is generated.

When the life value is less than the threshold, the temporary number becomes invalid and cannot initiate a call request, namely:

Pdi(CustId,t,num)＜Threshold(CustId,num) (Formula 7)

Through the above embodiments, user privacy is protected from two aspects: personal point-to-point call service and merchant call flow. Among them, the call control subsystem is aimed at the point-to-point communication call service of individual users, and judges in real time whether the status of the calling user is normal through the multi-dimensional characteristic value. If the authentication is passed, it means that the user is in a normal state, and the call is released. If the authentication is different, it means that the call is suspected of harassment or fraud. Traffic blocking. Compared with the existing technology, it can be prevented in advance, and the called user has no perception, and basically realizes the prevention of telephone harassment. The number authorization subsystem transforms the user's behavior of filling in the mobile phone number into the user's credit granting behavior for the merchant or website for the website merchant process. Open the user number authorization ability to external merchants through the capability open platform. If an external merchant needs to contact the user, it can query the user's temporary call number through the merchant, contact the user, and control the life value of the temporary number. The life value is less than the threshold When the temporary number becomes invalid, it is impossible to initiate a call request, thereby achieving the purpose of preventing the leakage of the phone number, and there is little change compared with the call flow familiar to existing users, without sacrificing user experience and changing the user's existing behavior to protect privacy Effect.
