FIG. 1 is a diagram illustrating a calling number changing system according to an embodiment of the present invention. FIG. 2 is a diagram illustrating an example of a screen displayed for user authentication in a mobile terminal included in the calling number changing system of FIG. 1 FIG. 3 is a diagram illustrating a process of changing a calling number by the calling number changing system of FIG.

1, the calling number change system 100 may include a mobile terminal 110 (or a user terminal, a mobile communication terminal of a user) and a mobile communication system 130. In addition, the calling number change system 100 may further include an authentication server 120 and a related authority server 140.

The mobile terminal 110 may be a terminal using a calling number service, for example, a terminal carried by a public official performing public service (for example, fire control, vehicle control, etc.). For example, the mobile terminal 110 may be implemented as a smart phone, a PDA, a smart pad, or the like.

The mobile terminal 110 may perform mode switching to change or not change the calling number. Here, the mode switching is a mode in which a first mode (or a basic mode) in which a base number (i.e., a number assigned by a mobile communication company to the mobile terminal 110) is used as a calling number and a second mode Or a secure mode). Here, the additional number may be stored in the authentication server 120, the mobile communication system 130, or the like set by the user or a company / organization to which the user belongs, Lt; / RTI >

The mobile terminal 110 may further include a separate application or communication module for performing user authentication, mode switching (or mode conversion), and the like, in order to use the calling number service. The communication module will be described with reference to FIG.

For example, the user can perform mode switching through a normal application execution process. 2, for example, the mobile terminal 110 may display a separate application execution icon IC1 to the user through the display module of the mobile terminal 110. [ In this case, the user can click the execution icon IC1, and when receiving the execution request of the application through the execution icon IC1, the mobile terminal 110 displays a user information input window (WIN_IN) can be displayed through the display module.

When the user authentication is successfully performed through the user information, the MT 110 transmits a mode change icon (Mode 2) (i.e., a transition from the first mode to the second mode is successfully performed, 2) mode is displayed on a part of the display module (for example, the upper part WIN_S indicating the status information of the mobile terminal 110), or a reception number A second icon IC2 such as " secure call (call originating number change call) " may be displayed in a part of the input window in a similar manner to the " call " button. When receiving an input for a " secure call ", the mobile terminal 110 uses the number change service and, otherwise, when receiving an input for a " call ", the mobile terminal 100 uses the base number The call can be performed. Meanwhile, the mobile terminal 110 periodically displays the screen shown in FIG. 2 (b), thereby preventing use of the caller ID change service by another user.

The mobile terminal 110 transmits a mode change request signal (or a second mode change permission request, a call number change service use permission request, etc.) to the authentication server 120 (or the mobile communication system 130) And can receive the personal code through the authentication server 120 (or the mobile communication system 130) in response to the mode change request signal. Here, the mode change request signal may include user information (e.g., name, ID, PW, etc.) and mobile terminal information (e.g., identification code).

The mobile terminal 110 can switch from the first mode to the second mode by receiving the personal code. In order to maintain the second mode, the mobile terminal 110 periodically transmits the mode change request signal at specific time intervals and receives the corresponding personal code.

On the other hand, the mobile terminal 110 transmits a reception number (i.e., a number assigned to the receiving terminal 160 to form a communication line with the calling mobile terminal 110) at the time of calling (or at the time of a call request) in the first mode (Or an outgoing call of the first type) that includes the first outgoing call. Alternatively, the mobile terminal 110 may transmit a second outgoing call (or a second type of outgoing call) further comprising a private code, upon origination in the second mode. For example, the second outgoing call may include a number change request signal (or an origination number change service request identifier, e.g., # 00 #), a personal code (e.g., 0000)

The authentication server 120 is connected to the mobile terminal 110 through a mobile communication network (and / or network), performs authentication for the mobile terminal 110 in response to a mode change request signal received from the mobile terminal 110 can do. Here, the mobile communication network may be a communication network established by the mobile communication system 130. For example, the authentication server 120 may authenticate the user or the mobile terminal 110 by matching the ID, PW, and the terminal information included in the mode change request signal with previously stored information.

In the embodiments, the authentication server 120 is installed in an organization, an enterprise, or the like to which a user who uses the mobile terminal 110 belongs. The authentication server 120 includes not only the user information (name, For example, during duty, duty in the US (work, leave, etc.)). For example, when the user is a firefighter, the mission status is set to ON or OFF according to the work or work, or the mission status is ON when the departure instruction is generated, and the mission is released Can be set to OFF (OFF).

In one embodiment, the mode change request signal includes user information of a user who owns the mobile terminal 110, and the authentication server 120 performs authentication based on the user information, You can verify the mission status and perform authentication. For example, when there is no user information matching the user information included in the mode change request signal, the authentication server 120 notifies the mobile terminal 110 that user authentication has failed due to " no matching user information " can do. For example, the authentication server 120 may provide the user terminal 110 with a user authentication failure because the user information is available but the mission status of the user is off (OFF) . For example, the authentication server 120 may transmit approval information for approving the mode change (that is, the mode change from the first mode to the second mode) when the task state of the corresponding user is ON, (110). Therefore, the authentication server 120 can prevent the user from arbitrarily abusing the origination number change service regardless of the performance of the mission.

On the other hand, when the authentication (that is, authentication to the user and / or the mobile terminal 110) is successfully performed, the authentication server 120 generates a personal code issuance request signal and transmits it to the mobile communication system 130 , And transmit (or forward) the received personal code to the mobile terminal 110 in response to the personal code issuance request signal.

Here, the personal code issuance request signal may include a basic number (or user information, mobile terminal information), and an additional number (that is, a number to be changed and used as a calling number).

The mobile communication system 130 (or the intelligent network system 133) may generate the personal code in response to the personal code issuing request signal. 1, the mobile communication system 130 includes a base station 131, an exchange 132, an intelligent network system 133, etc., and the exchange 132 is connected to a public network (not shown) The mobile terminal 110 and the like. Since the specific configuration of the mobile communication system 130 is described in Korean Patent Laid-Open Publication No. 2006-0116500 (published on November 15, 2006), " Calling method and system of mobile communication terminal using multiple numbers ", the mobile communication system 130 ) Will not be described in detail.

The personal code may be an authentication number or a password used by the corresponding mobile terminal 110 to use the origination number change service.

In one embodiment, the mobile communication system 130 may generate a personal code based on the additional number and the validity time included in the personal code issuing request signal. Here, the validity time may be set based on a sending time point or a receiving time point of the personal code issuing request signal. For example, the mobile communication system 130 can generate private codes using a specific formula, a specific encryption algorithm, and the like.

That is, the mobile communication system 130 generates a one-time personal code having a valid period, thereby preventing a user or another user from unauthorizedly using the calling number change service.

Meanwhile, the mobile communication system 130 may store the calling numbers of the corresponding user. For example, the mobile communication system 130 may store, as user information, a basic number of a user as a first calling number and an additional number as a second calling number. On the other hand, when receiving the personal code issuance request signal, the mobile communication system 130 compares the additional number included in the personal code issuance request signal with the pre-stored second calling number (i.e., the previously stored additional number) The number can be renewed. That is, when the mobile communication system 130 receives an additional number different from the previously stored second calling number, the mobile communication system 130 may update the second calling number by determining the request to update the additional number.

In embodiments, when the mobile communication system 130 receives a second outgoing call from the mobile terminal 110, it determines the validity of the second outgoing call based on the personal code included in the second outgoing call, If the outgoing call is valid, the base number may be changed to an additional number and transmitted to the receiving terminal 160.

In one embodiment, the mobile communication system 130 generates a personal code for verification based on the origination time and the additional number of the second outgoing call, compares the personal code included in the second outgoing call with the verification personal code, When the personal code matches with the verification personal code, the base number can be changed to the additional number and the outgoing call (that is, outgoing call with changed outgoing number) can be transmitted to the receiving terminal 160. That is, as described above, when the personal code is generated as the one-time code having the valid period, the mobile communication system 130 can determine the validity based on the valid period of the personal code received through the second origination call .

In one embodiment, the second outgoing call may further comprise a number change request signal and a second additional number. Here, the number change request signal is a code for requesting the calling number change, and may be a code having a predetermined format / size / length such as "# 00 # ". The second additional number may be a calling number that the user wants to change and use. In general, the additional number may be stored in the authentication server 120 and the mobile communication system 130, and may not be directly input by the user. However, when each of a plurality of users uses a plurality of origination number change services, it may take a lot of cost to store additional numbers. Therefore, the mobile communication system 130 may not store additional numbers separately in a database or the like. In this case, the authentication server 130 receives the additional number from the user in the user authentication step, determines the validity of the additional number based on the user information (for example, when the user belongs to the fire department and the representative number of the fire department , And requests the mobile communication system 130 to generate / issue a personal code for a valid additional number, and the mobile communication system 130 generates a personal code in response to the personal code issuing request .

Thereafter, when receiving the second outgoing call from the mobile terminal 110, the mobile communication system 130 transmits the personal code and the second addition from the second outgoing call based on the number change request signal included in the second outgoing call, And generates a verification personal code based on the calling time and the second additional number of the second outgoing call and compares the verification private code with the personal code included in the second outgoing call to determine whether to change the calling number You can decide.

For example, a second outgoing call for calling number change has a predefined format and a " number change request signal (e.g., # 11 #) + (E.g., # additional number #) " + " receiving number (e.g., 7 to 11 digits) Thus, the mobile communication system 130 may extract the private code and the second additional number from the second outgoing call.

Then, the mobile communication system 130 generates a personal code for verification based on the origination time and the second additional number of the second origination call, thereby determining whether the user has requested the origination number change within a valid time, Can be used to determine whether to use the additional number as the originating number.

Referring to FIG. 3, the mobile terminal 110 may operate in a second mode. 2, the mobile terminal 110 may operate in a second mode through a separate application or may be operated only through the coupling of the communication module 400, for example, via the communication module 400, 2 mode. In the second mode, the mobile terminal 110 may display a calling number change request icon together with a receiving number input window for requesting input of a receiving number. When receiving the origination number change request through the origination number change request icon, the mobile terminal 110 can transmit the second origination call. In this case, the calling number is unchanged and may be the same as the primary number.

On the other hand, the mobile communication system 130 (or the intelligent network system 133) determines suitability of the origination number change request using the personal code included in the second origination call, and when the origination number change request is appropriate, It can be changed to an additional number (for example, "119"). Accordingly, the mobile communication system 130 can transmit the outgoing call to the receiving terminal 160 (for example, the mobile terminal owned by the owner of the illegal driving car) with the additional number as the calling number. In particular, the mobile communication system 130 can specify a ring tone or the like based on an outgoing call with a specific ring tone (e.g., sirelable and vibration).

In this case, the receiving terminal 160 can easily identify the emergency situation by indicating the changed calling number, that is, the additional number, together with the specified ringing tone. That is, the reception ratio of the mobile terminal 110 can be improved.

On the other hand, when the call connection is not established with the user of the receiving terminal 160 in the second mode (i.e., the receiver is absent), the status information (e.g., vehicle position information) Company).

For example, the mobile terminal 110 may enter a picture taking mode for message transmission at the same time the call connection attempt is terminated. That is, the mobile terminal 110 executes / operates the camera included in the mobile terminal 110 and transmits information on the photograph or object of the object related to the receiving terminal 160 (for example, the vehicle number of the illegal driving car ). ≪ / RTI > Thereafter, the mobile terminal 110 automatically generates a message using the location information (or GPS position information) acquired through the GPS module provided in the mobile terminal 110 and the photograph of the object, and transmits the message through the mobile communication network or the like To the authentication server 120, the related institution server 140, and the related party terminal 150. Here, the related authority server 140 acquires detailed information (e.g., owner information) of the object in association with the position (or the GPS position information) or the object (for example, illegal driving vehicle) A local authority (for example, a city hall, a ward office), and the like capable of performing a disposition related to the object (for example, an administrative disposition, imposing a penalty on an object user, imposing a fines, etc.). The stakeholder terminal 150 may be a towing company that can process the object quickly.

For example, the mobile terminal 110 transmits a message including the location information and the object information to the authentication server 120, and the authentication server 120 searches / determines the relevant organization based on the location information and the object information , Request / obtain relevant information from the relevant authority (for example, the contact of the closest entrant, the contact of the owner of the illegally parked vehicle, etc.), and propagate the message to the party based on the party information.

As described with reference to FIGS. 1 to 3, the calling number change system 100 issues a personal code through authentication to the user / mobile terminal, and transmits the personal code to the calling number using the personal code included in the origination call of the mobile terminal. It is possible to determine the suitability or validity of the change service and to provide the finally changed calling number (i.e., additional number) to the receiving terminal 160 together with the outgoing call.

In addition, the calling number change system 100 checks the status of the user to perform user authentication, and generates a personal code as a one-time code having an effective time, thereby preventing the user from using the calling number changing service unauthorized other than work can do.

Further, the calling number change system 100 determines the calling number (i.e., additional number) to be changed by the user, determines the validity (i.e., availability) of the calling number and issues a personal code to the calling number service user (E.g., the cost of building a database to store the added originating number, etc.), and the user can change the originating number more freely and easily.

The calling number change system 100 automatically generates a message including location information, object information (e.g., car number) and the like when a call or connection is not established with the receiving terminal 160, (E.g., vehicle owner, trailer, etc.) to more quickly handle the tasks associated with the originating number change service.

4 is a diagram illustrating an example of a communication module of a mobile terminal included in the calling number change system of FIG.

Referring to FIG. 4, the communication module 400 may perform mode switching of the mobile terminal (for example, switching from the first mode to the second mode). When the communication module 400 is installed in the mobile terminal 110 instead of executing the application described with reference to FIG. 2, the authentication of the mobile terminal 110 is automatically performed, and the mobile terminal 110 May operate in the second mode.

The communication module 400 may be detachably attached to the outside of the mobile terminal 110 (for example, a mobile phone for public service). The communication module 100 may be manufactured to have a smaller size than the mobile terminal 110 and may be connected to the mobile terminal 110 through earphone jacks 410. Meanwhile, the communication module 400 may be manufactured with an ingress protection (IP) 68. In this case, the communication module 400 can protect the internal circuit from dust and flooding occurring at the disaster site.

The communication module 400 may include an earphone jack 410, a decoder 420, an encryptor 430, a processor 440, and a battery 450.

The earphone jack 410 is protruded to a specific length for insertion / connection into the earphone jack connection terminal 111 (or the insertion hole) of the mobile terminal 110 and is provided with an additional number provided by the communication module 400 The number to be used may be provided to the mobile terminal 100.

The decoder unit 420 (or the decoder chip) can identify the idle chip information included in the mobile terminal 110. For example, the decoder unit 420 may acquire user information, caller ID information, and the like stored in the invisible chip. The processing unit 440 described later can authenticate the mobile terminal 110 based on user information, calling number information, and the like.

The encryption unit 430 may encrypt the mobile terminal 110 to use the mobile communication system 130. For example, the encryption unit 430 can encrypt data transmitted and received using the mobile communication system 130. [

The processing unit 440 (or the main CPU) receives the basic number of the mobile terminal (for example, a unique originating number assigned to the public servant terminal) and the additional number (that is, ) Can be matched.

The processing unit 440 may automatically convert the base number registered in the base station to an additional number through the security chip 441, convert the basic number into an additional number, and transmit the converted base number to the receiving terminal 160.

On the other hand, the processing unit 440 performs user authentication based on user information and the like, and can generate a personal code based on an additional number or the like when the user authentication is successfully performed.

The battery 450 may supply power to the decoder unit 420, the encryption unit 430, and the processing unit 440.

As described with reference to FIG. 4, the mobile terminal 110 may provide the calling number change service through the communication module 400 installed in place of the application. The communication module 400 may perform the same functions as the application, independently perform user authentication, personal code issuance, and the like. Accordingly, the user using the mobile terminal 110 can easily use the origination number change service simply by attaching (or attaching / detaching) the communication module 400.

5 is a diagram illustrating a method for providing a calling number change service according to embodiments of the present invention.

Referring to Figures 1 and 5, the method of Figure 5 may be performed in the origination number change system 100 of Figure 1.

The mobile terminal 110 may receive a mode change request through an application or the like (S510).

The mobile terminal 110 may transmit a mode change request signal including user information (ID, PW, etc.) input from the user and terminal information to the authentication server 120 (S515).

The authentication server 120 may perform authentication for the user or the mobile terminal 110 based on the user information and / or the terminal information included in the mode change request signal (S520).

If authentication is successfully performed, the authentication server 120 may request the mobile communication system 130 to issue a personal code for the mobile terminal 110 (S530). Here, the personal code issuing request (or the personal code issuing request signal) may be a calling number, and may include a primary number and an additional number.

The mobile communication system 130 may generate / issue the personal code based on the additional number (that is, the number to be changed) and the sending time (or receiving time) of the personal code issuing request signal (S540). The generated personal code may be provided to the mobile terminal 110 (S545).

The mobile terminal 110 may perform mode switching from the first mode to the second mode when receiving the personal code (or when receiving the authentication result from the authentication server 120). That is, the mobile terminal 110 can use the origination number change service.

The mobile terminal 110 transmits a second outgoing call (or a second type outgoing call) in a second mode (S560), and the mobile communication system 130 transmits a second outgoing call (or a second type outgoing call) based on the personal code included in the second outgoing call If the second outgoing call is valid, the calling number may be changed from the basic number to the additional number (S570). Thereafter, the mobile communication system 130 may transmit an outgoing call to the receiving terminal 160 with an additional number as a calling number.

As described with reference to FIG. 3, the mobile communication system 130 can specify the display format of the outgoing call, such as syllabi and vibration, so that the user can more easily recognize the emergency situation. Meanwhile, the method of FIG. 5 can simultaneously transmit the message shown in FIG. 3 together with the outgoing call so that the user of the receiving terminal 160 can intuitively confirm the contents of the emergency situation.

6 is a diagram illustrating an example of a method for providing a calling number change service of FIG.
