In addition, the storage unit 170 stores the integrated spam list 172 according to the present invention in which spam keywords are stored.

5 is a diagram schematically illustrating a structure of an integrated spam list according to an embodiment of the present invention. Referring to this, the integrated spam list 172 is a place where spam keywords corresponding to all calls received from the outside are registered collectively and is configured in the form of a database including a plurality of fields. The integrated spam list 172 according to the present embodiment includes a spam keyword field, an item field, a condition field, and a call field. In addition, the call field according to the present embodiment includes not a single field but a plurality of fields, that is, a multimedia message field, a short message field, an e-mail field, and a call field. However, the present invention is not limited thereto, and a corresponding field may be further added to a mobile communication terminal capable of receiving other calls (for example, push messages, push to talk, etc.) other than the basic calls. The integrated spam list 172 will be described in detail later in the spam blocking method.

The controller 190 performs an overall control operation of the mobile communication terminal 100. In addition, the control unit 190 according to an embodiment of the present invention includes a spam keyword registration unit 192 and a spam processing unit 194 for spam processing.

The spam keyword registration unit 192 registers the spam keyword input from the user to the integrated spam list 172.

The spam processing unit 194 processes the received call based on the integrated spam list 172 when receiving a call from the outside.

Next, the spam blocking method according to the present invention will be described in detail with reference to the following examples. The configuration of the above-described mobile communication terminal 100 will also be clearer from the following description of the spam blocking method.

2 is a flowchart schematically illustrating a spam setting process of a mobile communication terminal according to the present invention, and FIG. 3 is a flowchart schematically illustrating a spam blocking process of a mobile communication terminal according to the present embodiment. 4A to 4F are diagrams illustrating a screen displayed according to the spam blocking method of the present embodiment.

First, the spam setting process will be described with reference to FIGS. 1, 2, 4A to 4E, and FIG. 5.

A process of receiving a spam setting request from the mobile communication terminal 100 in the standby state S11 is performed (S12). When the user operates the key input unit 160 of the mobile communication terminal 100 to request spam setting, the spam keyword registration unit 192 of the controller 190 recognizes this and displays the spam setting screen on the display unit as shown in FIG. 4A. (S13).

Referring to FIG. 4A, an address item and a title item are displayed on the spam setting screen. The address item according to the present embodiment is used when the spam keyword is to be limited to only an address (for example, an email address). On the other hand, in the present embodiment, when the received call is a call or a message (short message and multimedia message), the caller's number is used as the address. Therefore, a user selects an address item when he or she wants to enter a spam keyword corresponding to an e-mail address or a sender number.

Subject items are used to check spam keywords only by subjects included in the email. Here, the subject item according to the present embodiment is not limited to an e-mail, but may be extended to the content of a short message.

When the user selects a desired item from the address item and the title item through key operation while the address item and the title item are displayed (S14), the spam keyword registration unit 192 displays a spam keyword registration screen for the corresponding item (S15). ).

On the other hand, the spam blocking process according to an embodiment of the present invention is performed in a similar process for both address items and title items. Therefore, the following description will focus on the process of registering a spam keyword using an address item.

4B shows an example of a spam keyword registration screen displayed when an address item is selected. Referring to FIG. 4B, the spam keyword registration screen includes an input field A1 for inputting a spam keyword at the top of the screen, a portion A2 for selecting a search condition, and a portion for selecting an arc to which the inputted spam keyword is applied (A3). It is configured to include).

In the present embodiment, the portion A2 of selecting a search condition includes four conditions of 'include', 'match', 'start', and 'end'. 'Include' is a condition to classify the call as spam when the spam keyword is included in the item, and 'Match' is a condition to classify the call as spam only if the spam keyword is an exact match with the item. . In addition, 'start' is to classify the call as spam only if the item starts with a spam keyword, and 'end' is a condition for classifying the call as spam only when the item ends with a spam keyword.

In addition, in the present embodiment, the portion A3 for selecting a call is displayed to be basically impossible to select, and if there is a user's input, the corresponding call is changed to be selectable according to the input text. However, it is not limited thereto. On the other hand, the configuration of the spam keyword registration screen according to this embodiment is a configuration arranged only for the convenience of the user, the spam shown in Figure 4b It is not limited to the structure of a keyword registration screen.

When the spam keyword registration screen is displayed as shown in FIG. 4B, when the user inputs a desired spam keyword in the input field A1 through the key input unit 160 (S16), the spam keyword registration unit 192 displays the input word or phrase. The analysis identifies the call corresponding to the spam keyword (S17). For example, when the user inputs 'aaa@ahoo.com' in the input field A1 on the spam keyword registration screen for inputting an address item as shown in FIG. 4C, the spam keyword register 192 enters '@' in the input sentence. Be aware that is included. Through this, the spam keyword registration unit 192 determines that the input sentence is an email address.

As another example, when the user inputs '2580' in the input field A1 on the spam keyword registration screen for inputting an address item as shown in FIG. 4D, the spam keyword registration unit 192 recognizes that only numbers are input in the input box. Through this, the spam keyword registration unit 192 grasps that the input sentence is a calling party number.

The spam keyword registration unit 192, which grasps the type of the call corresponding to the spam keyword, changes and displays a portion A3 for selecting a call among the spam keyword registration screens (S18). In other words, as shown in FIG. 4D, only a call (eg, a multimedia message, a short message, and a call) corresponding to the input spam keyword (eg, '2580') can be selected and changed, and the remaining irrelevant calls (eg, an email) continue. Mark the selection as impossible.

Subsequently, the user selects a condition and a call to apply to the inputted spam keyword. In this case, when the user selects only the multimedia message and the short message as shown in FIG. Applies only to messages and short messages, not to calls or emails.

When each setting is completed through the above process and a storage request is received from the user (S19), the spam keyword registration unit 192 stores the set contents in the integrated spam list 172 as shown in FIG. 5 (S20). Referring to FIG. 5, spam keywords input by a user are input in a spam keyword field. In the item field, items selected by the user, 'address' or 'title', are entered. The condition selected by the user is entered in the condition field, and the call selected by the user is entered in the call field. Accordingly, when the setting is stored in the state shown in FIG. 4E, the integrated spam list 172 is stored as the number 2 record of FIG. 5.

Next, a spam blocking method for blocking spam using the set integrated spam list 172 will be described.

Referring to FIGS. 1, 3, 4F, and 5, the spam blocking process according to the present embodiment will be described. The call is received from the outside to the mobile communication terminal 100 in the standby state (S51) (S52). When the call is received, the controller 190 of the mobile communication terminal 100 extracts address information and title information from the received call (S53). For example, if the received call is an email, the sender's mail address is extracted as address information, and the subject of the email is extracted as the subject information. As another example, when the received call is a short message, the controller 190 extracts the caller number as address information from the received call. However, since the short message has no subject, the subject information is not extracted.

When the address information and the title information are extracted, the spam processing unit 194 of the controller 190 performs a process of determining whether the received call is spam or not by using the extracted address information and the title information. The spam processing unit 194 first checks whether the address information exists in the integrated spam list 172 (S54). The spam processing unit 194 targets records in which an item field is set as an address in the integrated spam list 172 and checks whether the extracted address information matches a spam keyword according to a set condition.

If the call received in step S54 is not determined to be spam, the spam processing unit 194 continuously performs a spam checking process using the title information (S55). The spam processing unit 194 checks whether the title information extracted for the records in which the item field is set as the title of the integrated spam list 172 includes the spam keyword. On the other hand, if the title information is not extracted in step S53, this process may be omitted.

When the address information or the title information matches the spam keyword in the step S54 and the step S55, the spam processing unit 194 checks the type of call to which the spam keyword is applied (S56). That is, the spam processing unit 194 checks whether the corresponding spam keyword is set to be applied to the currently received call through the integrated spam list 172.

If the call to which the spam keyword is applied in step S56 includes the currently received call, the spam processing unit 194 classifies the received call as spam (S57). Accordingly, the spam processing unit 194 performs a procedure such as rejecting a received call, deleting it immediately after receiving it, or keeping it in a spam message box and spamming the received call (58).

On the other hand, if there is no spam keyword in the title information in step S55, the controller 190 enters the process S59 and determines the received call as a general call rather than spam. In addition, even when the call received in step S56 is not set as a call applied to the spam keyword, the process goes to step S59 as well. Subsequently, the controller 190 connects the received call (in case of a call) or stores (in the case of a message or e-mail) and performs a processing procedure suitable for the received call (S60).

For example, the process of S52 to S58 described above will be briefly described as follows. When a short message is received from the caller '010­258­2580' in step S52, the controller 190 extracts 0102582580 as address information in step S53. In this case, the title information is not extracted because it is a short message. Next, in step S54, the integrated spam list 172 is used to determine whether the spam keyword is included in the address information '0102582580'. Referring to FIG. 5, among the records 1, 2, 3, and 6 in which an item is set as an address, only spam keyword '2580' of record 2 is included in the address information. The spam processing unit 194 checks the call that is applied to the second record in step S56. Record 2 is set to apply a multimedia message and a short message. Since the received call is a short message, the received call is included in the application of spam. Therefore, the spam processing unit 194 classifies the call received in step S57 into spam, and spam-processes the call received in step S58.

Here, the second record is set to apply only the multimedia message and the short message. That is, it does not apply when the call is a call. Therefore, in the above example, when the received call is a call, the received call is not classified as spam but is classified as a general call.

The spam blocking method according to an embodiment of the present invention performed through the above process stores and manages spam keywords in an integrated manner. Therefore, the user can easily set spam.

On the other hand, this embodiment describes an example of registering and blocking spam unconditionally by using an address item and a title item. However, the present invention is not limited thereto, and the method may further include activating / deactivating the address item and the title item in step S14. In this case, when the user selects an address item or a title item in step S14, the spam keyword registration unit 192 displays a screen for setting whether to activate the corresponding item as shown in FIG. 4F. Accordingly, when the user sets whether or not to activate the key, the spam keyword registration unit 192 activates / deactivates the corresponding item according to the user's setting.

If each item is set to be active / inactive through this process, only the activated items for all incoming calls will be checked for spam keywords.

In addition, as described above, the present embodiment describes an example of using only an address item and a title item. However, in addition to this, it is also possible to further include a content item including contents of an email or a message.

The spam blocking method and apparatus of a mobile communication terminal according to the present invention are not limited to the embodiments, and various modifications are possible by those skilled in the art within the technical idea of the present invention.

For example, the present embodiment uses a method of registering and blocking a spam keyword for an address and a subject of an incoming call. However, the present invention is not limited thereto. The spam keyword is targeted to a sender's IP address or a specific time. Various applications are possible, such as registering. In addition, the present embodiment describes an example of performing a phone number deletion method using a mobile communication terminal. However, any electronic device capable of receiving a call such as an e-mail or a message can be variously applied. In addition, in the present embodiment, after the spam keyword checking process is performed, a process of checking whether the received call is applied to the spam keyword is performed, but the present invention is not limited thereto. That is, after extracting a record to which the received call is applied, it is also possible to check the received call for the extracted records.

As described above, the method and apparatus for preventing spam in a mobile communication terminal according to the present invention can register and manage spam keywords integrally using an integrated spam list. In addition, spam keywords can be registered for each item such as an address and a title, thereby minimizing the inconvenience of individually setting spam for various calls.
