Description

Apparatus, method and application for spam processing {APPARATUS, METHOD, AND APPLICATION FOR PROCESSING SPAM CALL}

The present invention relates to an apparatus, method, and application program for processing spam, and more particularly, to an apparatus, method, and application program for determining a suspected spam number.

As personal portable mobile communication terminals, such as cell phones or smart phones, are positioned as devices owned by almost all members of society, unusual spam calls (including phishing, etc.) ) is on the rise.

Therefore, there is a demand for the provision of a service that prevents spam calls from being received or blocked in advance by collecting the phone numbers of the terminals that send spam calls, ie, spam phone numbers, and sharing them among terminal users.

To this end, the collection of spam phone numbers must be preceded. It is not easy to determine whether a spam phone number is a spam phone number with the efforts of only communication service providers, and the cooperation of each terminal user is required.

However, having each terminal user directly report a spam phone number when they receive a spam call is difficult to widely activate due to the inconvenience.

Therefore, it is necessary to add a function that enables the collection of spam phone numbers even if there is no special manipulation by the terminal user.

That is, in each embodiment, a plurality of signals transmitted at a predetermined time interval or transmitted after receiving a response signal from a counterpart device may be expressed as one signal name for convenience.

A schematic configuration of the entire communication system including the communication terminal 100 for spam processing according to an embodiment of the present invention is shown in FIG. 1 .

As shown in the figure, the entire communication system is configured to include a spam terminal 300 , a communication terminal 100 , and a spam number management server 200 .

Here, the spam terminal 300 is a terminal that makes a spam call, and may be a portable mobile communication terminal 100 such as a smart phone, a wired or wireless telephone provided in the house, and furthermore, a predetermined number given a phone number. It may be an exchange or a predetermined server.

In the present embodiment, the spam call is a broad concept including all types of calls that the recipient does not want, such as one-ring spam, ARS (Automatic Response System) outgoing spam, and telemarketing spam.

The spam number management server 200 receives and statistically manages the suspected spam number from the communication terminal 100, for example, when the same suspected spam number is received from different communication terminals 100, the corresponding suspected spam number It can be confirmed as a spam phone number.

In addition, the spam number management server 200 may aggregate spam call-related history information from the communication terminal 100 to determine the type of spam (eg, one ring, ARS transmission, telemarketing).

The spam number management server 200 may provide the spam phone number managed in this way according to the request of each communication terminal 100 so that each communication terminal 100 can recognize the spam phone number and take appropriate measures.

In FIG. 1 , the communication terminal 100 is a terminal that receives spam calls, and may correspond to a portable mobile communication terminal 100 such as a smart phone as well as a wired or wireless telephone provided in the house.

The communication terminal 100 analyzes the incoming call, determines whether to classify the phone number of the terminal that transmitted the incoming call as a suspected spam number, and transmits the result according to the determination to the spam number management server 200 carry out In addition, the communication terminal 100 may take an appropriate action after confirming by inquiring whether the caller number is a spam number from the spam number management server 200 when a call is received.

2 shows an example of a specific functional block of the communication terminal 100 .

As shown in the figure, the communication terminal 100 includes a call analysis unit 110 , a suspected spam number determination unit 120 , a transmission unit 130 , a storage unit 140 , and a call processing unit 150 . can be

The storage unit 140 stores programs and various information necessary for the operation of the communication terminal 100 , and in particular, also stores information generated or received during the operation of the communication terminal 100 .

In particular, the storage unit 140 may store the analysis result of the call analysis unit 110 to be described later.

The call processing unit 150 performs processing for incoming calls and processing for outgoing calls. For example, when an incoming call is received, the call processing unit 150 informs the user in various visual, tactile, and auditory ways, such as outputting a ringtone, and also the user. When the user receives an incoming call, the call is connected to the other party's terminal so that a call can be made with each other.

Similarly, the call processing unit 150 transmits an outgoing call to the counterpart terminal when the user makes a call, and also performs a function of making a mutual call when the counterpart terminal responds.

The call analysis unit 110 performs a function of analyzing the process from the end of the incoming call to the end of the incoming call.

Here, the termination of the incoming call includes not only termination after the incoming call is connected, but also ending before the incoming call is connected.

For example, when the call processing unit 150 outputs a ringtone as an incoming call is received and the call is terminated by the caller, the incoming call is terminated. can

The content analyzed by the call analysis unit 110 may include the originating number of the incoming call, the time until the incoming call is terminated, whether a mutual call is made before the incoming call is terminated, and the end of the incoming call.

Furthermore, the call analysis unit 110 may analyze whether the outgoing call is made in response to the previously received incoming call.

That is, when a call is made using the calling number of the corresponding incoming call as the incoming number after the predetermined incoming call is terminated, the call analysis unit 110 can analyze the process up to the end of the call for the outgoing call.

The suspected spam number determining unit 120 performs a function of determining whether to classify the originating number of the incoming call as a suspected spam number by using the analysis result of the call analyzing unit 110 .

For example, in the storage unit 140 , the analysis results of the call analysis unit 110 may be classified by the same caller number and stored cumulatively. It is possible to determine whether to classify each caller number as a suspected spam number by using the matched and accumulated information.

Here, the suspected spam number determining unit 120 is at least one of the call time information matched to each caller number, call end information, whether an incoming call is connected, whether or not information is sent to the corresponding caller number, and whether the caller number exists in the address book. You can use one to determine whether to classify the calling number as a suspected spam number.

For example, when an incoming call from the calling number 010-1111-1111 is terminated within 1 second, the suspected spam number determining unit 120 classifies the calling number 010-1111-1111 as a suspected spam number.

As another example, as a result of checking the analysis result stored in the storage unit 140 by matching a specific caller number, the suspected spam number determination unit 120 determines that the number of terminations within a preset time of an incoming call received from a specific caller number is set in advance. If it is higher than the standard value, the specific caller number may be determined as a suspected spam number.

To give a specific example, as a result of checking the analysis result stored in the storage unit 140, the suspected spam number determination unit 120 determines the total accumulated number of calls from the calling number 010-1111-1111 ending within 10 seconds. In the case of three or more times, the suspected spam number determining unit 120 may determine that the calling number 010-1111-1111 is a suspected spam number.

In addition, as a result of the analysis of the call analysis unit 110, the suspected spam number determining unit 120 determines that the incoming number of the outgoing call is suspected of spam when the outgoing call is terminated by the caller within a preset time after being connected to the other party, that is, the counterpart terminal. It can be determined by number.

For example, when a call is made to the calling number of the one-ring incoming call after the one-ring incoming call is terminated, the calling number of the one-ring incoming call becomes the incoming number of the corresponding outgoing call. As described above, the call analysis unit 110 analyzes the process until this outgoing call is terminated. At this time, the suspected spam number determination unit 120 is a call analysis result of the call analysis unit 110, after the call between the communication terminal 100 and the spam terminal 300 is made, when the caller who notices that it was a spam call immediately hangs up the call It is to determine the number of the destination number of the outgoing call as a number suspected of spam.

In the above-described various examples, the process of determining the suspected spam number when the suspected spam number determination unit 120 satisfies a predetermined condition has been described. After checking whether the number is registered in the address book, it is also possible to determine whether the number is a suspected spam number.

For example, in the case of a caller number determined to have sent a one-ring incoming call, if the caller number is a phone number already registered in the address book, the suspected spam number determination unit 120 will not classify the caller number as a suspected spam number. it can be

The transmission unit 130 performs a function of transmitting a suspected spam registration request signal including a corresponding caller number to the spam number management server 200 when the suspected spam number determination unit 120 determines that the number is a suspected spam number.

According to such a suspicious spam registration request signal, the spam number management server 200 may register and manage spam phone numbers.

Hereinafter, the overall control and signal flow of a communication system including the communication terminal 100 according to an embodiment of the present invention will be described with reference to FIG. 3 .

First, when the spam terminal 300 makes a call connection request to the communication terminal 100 (step S1), the communication terminal 100 extracts a caller number from the call connection request signal (step S3), and the extracted caller number It transmits a spam confirmation request signal to the spam number management server 200 (step S5).

Spam number management server 200 determines whether the caller number received from the communication terminal 100 is a spam phone number by searching for a list of pre-registered spam phone numbers (step S7), and determining the result of the determination in the communication terminal 100 ) to (step S9).

When it is determined that the outgoing number included in the call connection request is a spam number according to the determination result received from the spam number management server 200 (step S11), the communication terminal 100 performs spam call processing for the incoming call (step S27), for example, the communication terminal 100 may display a warning message informing that the call is spam.

When it is determined that the outgoing number included in the call connection request is not a spam number according to the determination result received from the spam number management server 200 (step S11), the communication terminal 100 performs normal processing for the incoming call (Step S13), for example, the communication terminal 100 processes a call connection so that the user can make a call with the spam terminal 300 when a ringing ring indicating that a call has come and the user receives it.

When the incoming call is terminated (step S15), the communication terminal 100 analyzes and stores the incoming call termination process (step S17), and determines whether the outgoing number of the incoming call is a suspected spam number according to a preset algorithm (step S17). S19).

When it is determined that the calling number of the incoming call should be classified as a suspicious incoming number (step S20), the communication terminal 100 transmits a suspicious spam registration request signal to the spam number management server 200 (step S21).

The suspected spam registration request signal transmitted by the communication terminal 100 to the spam number management server 200 may include a suspected spam number and information corresponding to the process until the incoming or outgoing call related to the suspected spam number is terminated. have.

Accordingly, the spam number management server 200 registers the suspected spam number (step S23), and generates and manages the spam number index (step S25).

For example, the spam number management server 200 statistically processes the information corresponding to the suspicious spam number received from each communication terminal 100 and the process until the incoming or outgoing call related to the suspected spam number is terminated, It is possible to generate and store the final spam number possibility and spam type of each suspected spam number, and provide it according to the request of the communication terminal 100 later.

Hereinafter, an example of a process in which the communication terminal 100 determines a suspected spam number according to an embodiment of the present invention will be described with reference to FIG. 4 .

After the incoming call is received (step S31) and before the connection is terminated (step S33), that is, when the incoming call is received but the incoming call reception is terminated by the caller before the user receives the call, the communication terminal 100 is For example, it is determined whether the incoming call is terminated within 1 second (step S35).

As a result of the determination, if the incoming call is terminated within a preset time (step S35), the communication terminal 100 determines that the outgoing number of the incoming call is a suspected spam number (step S37), and if the incoming call is not terminated within the preset time (step S37) The communication terminal 100 determines the originating number of the incoming call as a normal number (step S39).

If the incoming call is not terminated before the connection after the incoming call is received, the communication terminal 100 may determine the originating number of the corresponding incoming call as a normal number.

In this embodiment, classifying the number as a suspected spam number on the premise that the incoming call is terminated before the connection is an example, but it is of course also possible to determine whether to determine the suspected spam number only in step S35 without the process of step S33.

Hereinafter, another example of a process for determining a suspected spam number by the communication terminal 100 according to an embodiment of the present invention will be described with reference to FIG. 5 .

When the outgoing call is transmitted (step S41) and the outgoing call is connected (step S43), that is, when the user makes a call and the other party receives the call, the communication terminal 100 checks whether the outgoing call is terminated by the caller within a preset time do (step S45).

As a result of the check, if the outgoing call is terminated by the caller within a preset time (step S45), the communication terminal 100 determines the incoming number of the outgoing call as a suspected spam number (step S47), and as a result of the check, exceeding the preset time When the outgoing call is terminated or the outgoing call is terminated by the called party, the called number of the outgoing call is determined as a normal number (step S49).

Meanwhile, it goes without saying that the process of performing each of the above-described embodiments may be performed by a program or application stored in a predetermined recording medium (eg, computer-readable). Here, the recording medium includes an electronic recording medium such as a random access memory (RAM), a magnetic recording medium such as a hard disk, and an optical recording medium such as a compact disk (CD).
