All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a method for defending against malicious calls according to an embodiment of the present invention.
As shown in fig. 1, the method for defending against malicious calls provided by the embodiment of the present invention specifically includes the following steps:
s11, judging whether the calling party of the current call is a malicious number;
the embodiment of the invention judges the current call of the user, for example, comprehensively judges according to the calling behavior, the called behavior and the calling credit to determine whether the current call is a malicious call initiated by a malicious number.
S12, when the calling is a malicious number, transferring the current call to a number in a number resource pool;
the embodiment of the invention provides a number resource pool, which provides a plurality of forwarding numbers so as to select the forwarding numbers from the number resource pool for call forwarding after judging malicious calls, thereby avoiding the disturbance of the malicious calls to users and providing real-time protection for the users.
And S13, processing the current call through the number in the number resource pool.
The embodiment of the invention transfers the malicious call and processes the malicious call through the number in the number resource pool which is responsible for transferring. The specific processing mode comprises the modes of not answering the malicious call through the transfer number until the call is finished, refusing, calling back after refusing and the like, wherein the mode of calling back the malicious number through the transfer number after refusing or finishing the call can confirm the calling misjudged as the malicious number so as to properly process the call, in addition, certain interference can be caused to the real malicious number, the malicious call behavior is prevented from continuing, and the counter-control to the malicious number is realized.
According to the method for resisting the malicious call provided by the embodiment of the invention, after the calling party of the current call is judged to be the malicious number, the current malicious call is transferred to the number in the number resource pool, and the malicious call is processed through the transfer number. The embodiment of the invention can avoid the user from being disturbed by the malicious call by transferring the malicious call, and provide real-time protection for the user.
On the basis of the foregoing embodiment, S12 specifically includes:
when a plurality of malicious numbers continuously call the current called party, the calls initiated by the malicious numbers are transferred to the numbers in the number resource pool, wherein the number of the numbers is the same as the number of the malicious numbers initiating the calls.
Specifically, when a lawbreaker uses a plurality of numbers to make continuous and uninterrupted malicious calls to the same user, the embodiment of the invention provides the same number of forwarding numbers for the user, and respectively answers the calls sent by each malicious number.
In the specific implementation process, the forwarding mode may forward the malicious call to the number of the number resource pool through an IMS (IP Multimedia system) or a softswitch system. The embodiment of the invention can protect the user from continuous attack of malicious numbers.
The number resource pool provides a plurality of transfer numbers for the user, the user needs to obtain the authority of using the number resource pool for using the number in the number resource pool, for example, in the specific implementation process, the user needs to apply for a service for resisting malicious calls first, and the time period for using the service needs to be clear, and the authority of using the number in the number resource pool can be obtained only after applying for using the malicious call resisting service. The number resource pool provided by the embodiment of the invention can be shared by all users applying for services in a time division multiplexing mode, so that the number of required transfer numbers can be reduced, and the occupation of resources is reduced.
Specifically, the numbers in the number resource pool include an online number and an offline number.
The embodiment of the invention adopts a mode of combining an online number and an offline number to form a number resource pool, wherein the online number refers to the number always in an online activation state, the offline number is activated online when the number is used, and the number is released to be offline. The method for combining the online number and the offline number provided by the embodiment of the invention can ensure convenience, reduce occupied resources and improve the utilization rate of the number resource pool.
On the basis of the foregoing embodiment, the S12 specifically further includes:
when a plurality of malicious numbers continuously call the current called number, preferentially transferring the call of the malicious numbers to online numbers in a number resource pool;
when the number of the online numbers in the number resource pool is insufficient, activating the corresponding number of the offline numbers, and transferring the malicious calls which are not transferred to the online numbers to the activated numbers;
and after the malicious call is processed through the activated number, releasing the activated number as an offline number again.
In the embodiment of the invention, when the number is selected from the number resource pool, the online number is preferentially selected, when the online number resource is insufficient, the offline number is selected, the online number is activated firstly, then the corresponding malicious call is answered, and the offline number is converted into the offline state again after the malicious call is processed, so that the occupied resource can be released, and the number resource pool can be reasonably utilized.
On the basis of the foregoing embodiment, S13 specifically includes:
and not answering the call of the malicious number, or directly rejecting the call of the malicious number, or after rejecting the call of the malicious number, replying a short message to the malicious number or calling back the malicious number through the number in the number resource pool.
The embodiment of the invention finishes the malicious calling through the number in the number resource pool after the number in the number resource pool answers the malicious calling, and provides a processing mode for countering the malicious number, which specifically comprises the following steps: the short message is not answered until the calling party stops calling, directly refuses or replies a short message to the calling party after directly refusing.
Specifically, after the malicious call is finished, under the condition that the user perception is not influenced, the malicious number is dialed back through the number in the number resource pool, if the calling party is a normal number which is judged to be the malicious number by mistake, the dialing back mode conforms to a normal flow, and the interference to a normal user can not be caused; if the misjudgment is not carried out, certain interference can be caused to the malicious number, the malicious number is prevented from continuing to carry out malicious calling, and the purpose of carrying out certain countermeasures on the malicious number is achieved.
On the basis of the above embodiment, after S13, the method further includes:
and playing the voice message to the malicious number which is answered within the specified callback times.
Specifically, if the malicious number answers the call-back, the voice is recorded to the malicious number automatic playing system, and the number which requests to answer the call-back carries out voice mailbox message leaving to the user.
The method for countering a malicious number by using a callback proposed by the present invention is described in detail by using specific examples.
For example, a calling party a calls a subscriber B, and after judging that a is a malicious number, a forwarding number C is allocated by the number resource pool to answer the call of a.
Fig. 2 is a schematic flow chart illustrating a procedure for countering a malicious number according to an embodiment of the present invention.
Referring to fig. 2, the step of countering the malicious number includes:
1) after the call of the malicious calling A is transferred to the number C, the selectable treatment mode through the number C comprises the following steps: not answering until the calling A stops calling, directly refuses to answer or replies the short message after directly refusing to answer;
2) then taking C as a calling party to dial a malicious number A, and setting a maximum dialing frequency threshold to be N (N can be set to be 2 by default);
3) judging whether the dialing frequency does not exceed the maximum dialing frequency N;
if not, judging whether the A answers the call: if the A does not answer the call, returning to the step 2; if A answers the call, continuing to step 4; if the dialing frequency exceeds N, entering step 5;
4) after A receives the call, C automatically plays the system record to request A to leave a message in the voice mailbox to the user B;
5) and ending the malicious number reverse-making process, releasing the number C, and returning the number C to the number resource pool.
On the basis of the foregoing embodiment, S11 specifically includes:
if the calling party of the current call is smaller than a first threshold value in the first specified time as the calling party, judging that the calling party of the current call is a malicious number, wherein the calling party of the current call is the ratio of the calling party to the busy hour;
if the called time length ratio of the called party of the current call in a second specified time length is larger than a second threshold value, judging that the calling party of the current call is a malicious number, wherein the called time length ratio is the ratio of the busy hour time length of the called party to the second specified time length;
and if the marking state of the calling party of the current call in the shared number marking library is a harassing call and the marking times are greater than a third threshold value, judging that the calling party of the current call is a malicious number, wherein the shared number marking library comprises numbers marked as harassing calls and the marking times of each number.
The method for judging whether the current calling is the malicious number combines the analysis and judgment of multiple dimensions of the calling behavior, the called behavior and the calling credit.
The caller behavior analysis, the callee behavior analysis, and the caller reputation analysis are explained in detail below, respectively.
And (3) calling behavior analysis: and calculating the calling time ratio of the current calling party as the calling party within a certain time, wherein if the calling time ratio of the current calling party as the calling party is very low, the probability of the calling party being a malicious call is higher.
Specifically, a signaling call ticket in which a current calling party is used as a calling party within a certain time is obtained, and the calling party call duration ratio is calculated according to the calling party call duration and the busy hour duration recorded in the signaling call ticket: and if the calling call duration ratio is smaller than a first threshold, judging that the current calling is a malicious number.
The calling call duration is the total duration of the call connection of the calling party recorded by the same calling signaling ticket; the busy hour duration is the total duration recorded in the same calling signaling ticket (i.e. from the starting time of signaling establishment to the ending time of signaling).
And (3) called behavior analysis: analyzing the time length ratio of the called party in the last period of time under the condition that the current called party is the called party, and if the time length ratio of the called party in the last period of time is higher, the probability that the called party is in a malicious calling state is higher.
Specifically, a called signaling ticket of a current called party in a certain test period (for example, 3 minutes) is obtained, and the ratio of the called duration to the called duration is calculated according to the called busy duration recorded in the signaling ticket: and if the ratio of the called duration to the total duration is greater than a second threshold, judging that the current called party is in a malicious calling state and the current calling party is a malicious number.
The busy time duration is the total duration recorded in the called signaling ticket of the same called party (i.e. from the starting time of signaling establishment to the ending time of signaling), and the total duration is a specified time period (e.g. 3 minutes).
And (3) caller reputation analysis: the method mainly analyzes the marking state of the number as the calling in the shared number library to judge whether the calling is a malicious number, and if the calling is marked as a harassing call and the marking frequency is higher, the probability that the calling is a malicious number is higher.
Specifically, the shared number tagging library provided by the embodiment of the present invention records numbers of nuisance calls, nuisance types (such as sound, advertisement promotion, etc.), and tagging times of each number. If the current caller is marked as a harassing call (such as ringing one sound) and the marking times exceed a preset value, the current caller is judged to be a malicious number.
After judging that the calling party of the current call is a malicious number, the embodiment of the invention stores the judged malicious number into the shared number mark library and marks the type and the frequency of harassment.
The judging mode combining the calling and called behaviors and the number historical credit provided by the embodiment of the invention greatly improves the accuracy of judging the malicious call.
On the basis of the foregoing embodiment, before S11, the method further includes:
judging whether the calling party of the current call is in a white list or a black list of the called party of the current call;
if the calling party of the current call is in the white list of the called party, directly establishing the call;
and if the calling party of the current call is in the blacklist of the called party, refusing to establish the call.
Specifically, the embodiment of the invention provides a grey-black calling classification mode according to the trust degree, which does not influence the normal conversation of a user and simultaneously reduces the analysis range of malicious calls. The user can set the trusted caller as a white list, set the caller determined to be untrusted as a black list, default the rest callers as a gray list, and judge the malicious number by the step of S11 provided by the embodiment of the invention when the number of the gray list is incoming, wherein the processing of the number in the black and white list comprises the following steps:
when a calling party A calls a user B, firstly, judging whether the A is in a calling white list set by the B, and if the A is in the white list, directly calling the B;
if not, judging whether A is in the call blacklist set by B, if so, stopping the call.
The method for processing the call based on the black, white and grey list provided by the embodiment of the invention can reduce the judgment range of malicious calls under the condition of not influencing the normal conversation of the user.
