The present invention relates to a method for automatically identifying and blocking various types of spam calls that are unilaterally sent to the called party in the telephone network and visually and / or acoustically.

Conventionally, in order to block a spam call, the caller directly blocks the call from the service provider of the telephone company and notifies each of the individual spam phone numbers to an agent. Individual spam phone numbers can be blocked, but in general, spam calls are rarely sent from the same caller number more than once for one called number, which is not enough to prevent unspecified spam calls. That's enough.

The present invention, in view of the problems of the prior art as described above, by the recipients to easily report the incoming spam calls and share this information, not only the spam calls received by the recipient, but also the spam calls not received by the recipient in advance Provides the ability to block. This is because spam calls are usually not repeatedly received by the same recipient in a short time, so it is important to be able to identify and block them in advance.

In addition, the present invention manages the degree of spam of spam calls by grade, and provides a function to visually and audibly check the spam grade of spam calls when the called party automatically blocks or incoming calls according to the grade, Provides the ability to reject incoming calls. In addition, such a visual confirmation function can be provided through a conventional telephone.

In addition, the present invention provides a hotkey (HOTKEY) in a dedicated phone, it provides a function that can be registered quickly and easily. In addition, a dedicated telephone can be used to provide various visual / acoustic identification and blocking functions for spam calls.

Finally, the present invention provides a function that can provide the same functions of spam reporting, spam classification, spam blocking and identification even for spam calls received from a landline phone to a mobile phone. Since spam calls are primarily sent from landlines to mobile phones, this provides a very important advantage.

The present invention comprises a process for reporting, discriminating and classifying spam calls, blocking by a telephone network, blocking by a terminal, and visual / acoustic identification of spam calls.

1 shows a procedure for a recipient to report a spam call in a conventional general telephone. You can also report spam easily from a regular phone or report a random number.

a) Spam caller (a device for generating a spam call, which may be a wire / wireless phone terminal or a voice processing device such as ARS / IVR) sends a spam call.

b) Spam calls are received by the called party. At this time, since the called party is the subscriber of the service, logic from b) to k) of FIG. 7 or from b) to l) of FIG. 8 is executed. In this process, if the call is blocked, the following c) below is not executed.

c) The called party ends the call.

d) In the case of a spam call, the called party shall report the call by connecting the call to the designated telephone number.

e) In general telephones, a call is made to a specific short phone number, such as a specific phone number + CALL, to notify the spam blocking server that the incoming call is a spam call. The specific telephone number is * XX + CALL, 1588 + CALL, and the shorter the better. The calling number can be specified directly in the same way as the specific telephone number + calling number + CALL, but in this case, any call can be reported.

f) 'final called number' is retrieved from the information of FIG.

g) From the information of FIG. 6, it is determined whether the 'last destination number' is valid using the 'last destination time'. In this case, it is not normal, but to prevent spam from being reported in the normal state of system failure.

h) The confirmed blocking number is stored in the data as shown in FIG. 3 by the procedure a) of FIG.

i) By the spam blocking server, the report is automatically terminated.

Figure 2 shows a procedure for reporting a spam call using a dedicated telephone having a dedicated button (HOTKEY) for spam reporting. Dedicated phone has a button (HOTKEY) or menu for reporting for this service, and analyzes the calling number and calling name to recognize spam calls and ratings, and accordingly, the incoming call screen, ringtone, blocking function It is a terminal that can provide.

a) same as a) of FIG.

b) same as b) of FIG.

c) same as c) of FIG.

d) In the case of a spam call, the called party shall report it by selecting a button or menu of the dedicated terminal. At this time, the terminal stores the calling number of the last incoming call as a spam telephone number. Therefore, the called party is prevented from reporting any number.

e) The terminal reports spam to the spam blocking server. There are two ways of reporting such as through voice call and data transmission. In case of using voice call, the terminal makes a call like a specific phone number + blocking number + CALL. Therefore, the same method as * XX + block number + CALL, 1588 + block number + CALL is possible. The data transmission method is a method of accessing a spam blocking server through a data connection and transmitting a 'blocking number' as data.

f) same as h) of FIG.

g) Spam report is complete and connection is released.

However, even in the case of a dedicated terminal, a call that is received immediately before the spam blocking server is generated by generating a call using the (button or menu) + CALL method as shown in FIG. You can also report spam.

Figure 3 shows the subscriber-specific blocking information stored in the spam blocking server. This data is stored and managed to have the following functions:

(1) It manages blocking and allowed telephone numbers for each subscriber. The blocking number set by the subscriber is to block with the highest priority. Therefore, the blocking number in this information has the highest priority and is a number that does not have any problem even if automatically blocked.

(2) When the called party wants to receive the number determined as spam phone by Fig. 4, it provides the function that the called party can make the 'spam status' of this data as 'allow'.

(3) For all subscribers, it is used to block or allow any number.

(4) Used as information for calculating the data in FIG.

In FIG. 3, the spam state indicates that the subscriber directly blocks or allows the blocking number. 'Blocking' setting is by the procedure of Figs. 1 and 2, and 'Allowing' is set when the user expressly intentions to call the corresponding number through the customer center or setting function. In the state of 'allow', even if this number is in the block number list of Fig. 4, the call is allowed to the subscriber. If 'ALL' in 'subscriber's phone number' means that it applies to all users. Thus, through this function, it provides a function to block or allow any number for all subscribers.

4 is information for managing a block number and a rating analyzed by FIG. This information is periodically analyzed and updated through the procedure shown in FIG.

FIG. 5 illustrates a procedure of generating and updating data of FIG. 4. Through this process, the spam phone number and rating are determined by analyzing the number of blocked or allowed subscribers to a specific blocked number. Through this, certain blocked numbers exhibit a service effect that is blocked in advance for other subscribers.

a) With reference to Figs. 1 and 2, a block number is set in Fig. 3.

b) A block number is allowed in FIG. 3 by a subscriber request.

c) For each blocking number registered in FIG. 3, through the following procedure d), whether or not to block is determined.

d) In FIG. 3, the number of subscribers who block or allow the blocked number is retrieved. These are called 'blocked subscribers' and 'allowed subscribers', respectively.

e) In Figure 4, the entire 'call-to-call' of the blocking number is inquired.

f) Calculate the 'blocking rate', such as 'blocking rate = number of blocked subscribers / calls received'.

g) Calculate the 'Allowed Rate', like 'Allowed Rate = Allowed Participants / Received Calls'.

h) Determine whether or not to block. The higher the 'call-to-call', the higher the 'blocking rate', and the lower the 'allowed rate', the higher the blocking level. Do not block in case of 'None' grade.

i) Record the result in the information in FIG.

6 is for storing information related to a subscriber. 'Blocking grade' is the cutoff grade set by the subscriber. If the set level or more, the call is blocked in the same manner as in FIG. 'Last Called Number' is a record of the last called number of subscribers and is used in FIG.

Figure 7 shows a procedure for switching off a call when a call of the blocked number is received by the subscriber. As shown in FIG. 3, the subscriber blocks the number directly blocked, and the blocking number shown in FIG. 4 blocks the grade or more set by the subscriber.

a) The spammer sends a spam call. It may be a wired or mobile subscriber.

b) The destination exchange requests the service control system to inquire and execute the service subscribed to by the called party. The service control system is an apparatus for providing various additional services by participating in a connection process of a telephone call. Typically SCP, HLR, etc. are used. In wireless networks, HLRs may be used, and in wired networks, SCPs may be used. In the case of a wired network, the destination exchange can inquire whether the service is subscribed by itself, and in the case of a mobile network, it is inquired whether or not it is subscribed to the 'service control system'.

c) determine which services the called party subscribes to.

d) If the subscriber is a service subscriber, request the service to spam blocking server.

e) Record the calling number as 'final destination information' in Fig. 6, and also record 'final destination time'.

f) The spam blocking server uses the called party number and the calling party number to query the 'spam status' for the <subscriber's phone number and blocking number> in the information of FIG.

g) If the 'spam status' of FIG. 3 is 'blocked', l) is executed.

h) Inquiry 'blocking grade' in FIG. If none, execute k).

i) Check the 'grade' of the calling number in FIG.

j) If the calling party's grade is higher than the grade set by the user, it is blocked. In other words, l)

k) Connection without blocking. When the normal call processing is notified to the 'service control system', the 'service control system' instructs the destination exchange to normal call processing.

l) The call is blocked.

m) Notify the service control system of the voice module access number of the spam blocking server.

n) 'Service control system' informs the destination exchange to connect to this access number.

o) The destination exchange connects the call to the voice module of the spam blocking server.

p) The spam blocking server sends out announcements.

q) The anti-spam server may additionally carry out a counter-notification procedure. In other words, the sender registers an objection to the blocked call as a spam call.

r) The guide call ends. Or, the call is automatically terminated by the calling party.

8 is a procedure for visually and audibly displaying a spam level of an outgoing call on a terminal to allow a called party to determine whether an incoming call is made, and also, in the case of a dedicated terminal, a function of blocking a call at the terminal. In particular, by automatically activating the outgoing call number service or call name service and modify the information, so that the spam call is automatically displayed in the general terminal.

a) same as a) of FIG.

b) same as b) of FIG.

c) same as c) of FIG.

d) same as d) of FIG.

e) same as e) of FIG.

f) Referring to FIG. 3, if the 'spam status' of the calling number is 'blocked', it is regarded as the highest blocking level. Once the rating has been made, perform h) or below.

g) Inquiry to Figure 4, to query the grade of the calling number.

h) transmit the rating to the 'service control system';

i) If it is not a block number, normal call processing is executed and terminated. If the blocking number has a blocking level, execute j) or below.

j) If the called party is not a subscriber to the 'calling number indication service', it is regarded as a subscriber of such service, and the service is activated. In addition, if the called party is not a subscriber to the 'calling name display service', it activates the service. K) If the caller does not provide the caller name or if the caller does not have the caller name through the wired network, or if the caller does not have the caller name information by using the Caller Name Restriction Service or other roaming, as in k). Include spam rating information

k) In case of using the 'calling number display service', a letter is added to the 'calling phone number' to indicate the spam level. That is, for example, the spam level is indicated by the number of '*', such as the calling number + '***' or the spam level is changed by changing the character. So, if the grade is low, it is displayed as calling number + '*'. On the other hand, depending on the network, two calling numbers may be used. In this case, the spam level is displayed instead of any one calling number.

In addition, when using the 'call name display service', the name set by the sender is replaced with a letter indicating the spam level or adds a spam level character to the sender set name. If the sender doesn't have a name, the spam letter is added. That is, spam grade characters such as 'high spamming' are replaced or added to the sender's set name. These phrases can be modified in various ways.

l) Notify the destination exchange of call connection information. At this time, the data related to the previously set 'calling number display service' or 'calling name display service' is included.

m) The called exchanger connects the call with the called party. At this time, the data of l) is also transmitted.

n) If the called terminal is a general terminal and a terminal capable of 'calling number display service' is available, the number set in k) is output, and a letter '*' is displayed for the called party to visually determine the spam level. In addition, if the terminal is a terminal capable of 'calling name display service', the name set in k) (high spamability) is displayed on the called screen, so that the called party can visually determine the spam level.

o) In the case of a dedicated terminal, it analyzes the information of the 'calling number' or 'calling name' modified in k), determines the rating, and indicates that it is a spam call through the visual image or video determined in the rating. In addition, by outputting the specified ringtone, it provides a function to identify audibly, when set to vibration, the ringtone does not come out. This function is a function that a called party can set in the called terminal.

p) By setting the called party, the terminal provides the call blocking or auto answering function according to the class.

When providing an identification service using the 'calling name display service' in FIG. 8, the procedure of i) to k) may be directly performed by the spam blocking server according to the network configuration. In this case, the network configuration is possible when the 'service control system' is composed of HLR and 'spam blocking server' is composed of SCP.

Figure 9 shows that when outputting the calling number in a general terminal having a calling number display function, it is visually seen that the spam call. As shown in k) of FIG. 8, the called party can know the spam call and the rating through the calling number and '***'.

Figure 10 shows that when you display the calling name in a general terminal having a calling name display function, it is visually showing that the spam call. The result set by k) of FIG. 8 is the same, and the called party can know the spam call and the grade through the calling number and '[high spam level]'.

FIG. 11 shows a dedicated terminal capable of determining a spam call and a rating by recognizing an outgoing call and a call name specified by the spam blocking server. In this case, using a preset image and video to visually indicate that the spam call, and distinguished acoustically through the set ringtone.

12 shows a case where the terminal blocks the incoming call of spam by recognizing the designated outgoing call and the outgoing name modified by the spam blocking server. Spam calls above the level set by the called party are automatically blocked.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, but various improvements, modifications, substitutions or additions can be made without departing from the gist of the present invention. Those skilled in the art will readily understand.

For example, the contents of the call number, the call name modification, and the output method in FIGS. 8 k and 9, 10, 11 may vary depending on the character used.

In addition, depending on the network configuration of the wired and mobile networks, the 'service control system' and the 'spam blocking server' may be configured as one system or may be configured separately.

In addition, in step e) of FIG. 2, an additional registration channel such as an SMS may be utilized according to a method in which the terminal may access the spam blocking server.

In addition, the classification step of "grade" of Figure 4 may be configured differently.

On the other hand, in Figures 1 and 2, the order of ending the declaration is irrelevant to the procedure. That is, since they all occur at the same time, they may be terminated before or after.

By using the present invention as described above, it is possible to automatically identify and block various spam calls unilaterally received by the called party in the telephone network, and visually and audibly.
