Referring to FIG. 1 , the calling number change system 100 may include mobile terminals 110a and 110b (or a user terminal, a user's mobile communication terminal) and a mobile communication system 130 . In addition, the calling number change system 100 may further include an authentication server 120 and a related institution server 140 .

Each of the mobile terminals 110a and 110b is a terminal using a caller ID service, and may be, for example, a terminal possessed by a public official who performs official duties (eg, fire suppression, vehicle control, etc.). Each of the mobile terminals 110a and 110b may be collectively referred to as a mobile terminal 110 . For example, the mobile terminal 110 may be implemented as a smart phone, a PDA, a smart pad, or the like.

According to an embodiment, when the first mobile terminal 110a is a terminal used by the first user, the second mobile terminal 110b is a terminal used by a second user who performs work (or official duties) together with the first user. can be

The mobile terminal 110 may perform mode switching in order to change the calling number. Here, mode switching is a first mode (or basic mode) using a basic number (that is, a number given by a mobile communication company to the mobile terminal 110) as a calling number and a second mode ( Alternatively, it may mean switching between security modes). Here, the additional number is preset by the user or the company/organization to which the user belongs and is stored in the authentication server 120 or the mobile communication system 130 to be described later, or the user sets the mobile terminal 110 according to the execution of the task. can be transmitted externally.

The mobile terminal 110 may further include a separate application or communication module that performs user authentication, mode change (or mode change), etc. in order to use the caller ID service. The communication module will be described with reference to FIG. 4 .

For example, a user may perform a mode change through a normal application execution process. Referring to FIG. 2A , 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 a request to execute the corresponding application through the execution icon IC1, the mobile terminal 110 displays a user information input window requesting input of user information. (WIN_IN) can be displayed through the display module. Here, the user information may include a user's identification number (eg, ID or user code) and password (PW). According to an embodiment, the user information may include biometric information (eg, iris, fingerprint, etc.).

When user authentication is successfully performed through the user information, the mobile terminal 110 displays a mode change icon Mode2 (that is, the change from the first mode to the second mode is successfully performed, and the mobile terminal 110 2) is displayed on a part of the display module (for example, an upper part (WIN_S) indicating the status information of the mobile terminal 110) or a reception number for inputting a reception number for a call Similar to the “call” button, a second icon IC2 such as “secure call (ie, caller ID change call)” may be displayed on a part of the input window.

When receiving an input for "security call", the mobile terminal 110 uses a number change service. On the other hand, when receiving an input for "call", the mobile terminal 110 uses a basic number You can make calls. On the other hand, the mobile terminal 110 may periodically display the screen shown in FIG. 2B to prevent other users from using the calling number change service.

In one embodiment, when receiving an input for a “secure call” from the user (ie, receiving a request for transmission of the second outgoing call from the user), the mobile terminal 110 transmits the corresponding secure call (ie, the second outgoing call). 2), an input of incoming call setting information regarding whether to receive an incoming call from the receiving terminal 160 may be prompted.

Referring to FIG. 2B , for example, when receiving an input for “secure call” from the user, the mobile terminal 110 outputs a message such as “Do you want to allow incoming calls to the above number” on the display, and for this A user's input, that is, an input for call setting information may be received.

When receiving the call setup information from the user (for example, when receiving information indicating that the call is allowed), the mobile terminal 110 transmits the second outgoing call and information on the second outgoing call and the incoming call. Setting information (eg, call permission information for a specific number) may be provided to the authentication server 120 . The authentication server 120 to be described later separately stores the incoming call number of the mobile terminal 110, and when receiving an incoming call corresponding to the additional number from the receiving terminal 160 corresponding to the incoming call allowed phone number, It may request the mobile communication system 130 to forward the incoming call to the mobile terminal based on the call setup information. That is, the authentication server 120 may process an incoming call received from the receiving terminal 160 corresponding to the incoming call allowed phone number, and retransmit the call to the mobile terminal 110 in which the incoming call is allowed.

In some cases, a user using the mobile terminal 110 may need to make a direct call with the receiver of the receiving terminal 160 . Accordingly, the user can separately set up a call to a specific number.

In an embodiment, the mobile terminal 110 receives a mode change permission signal from the authentication server 120 through an application, and performs a mode change from the first mode to the second mode or a second mode change permission signal based on the mode change permission signal mode can be maintained.

In another embodiment, the mobile terminal 110 sends a mode change request signal (or second mode change approval request, caller number change service use approval to the authentication server 120 (or the mobile communication system 130) through an application) request, etc.), and may 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 (eg, name, ID, PW, etc.) and mobile terminal information (eg, identification code). The mobile terminal 110 may switch from the first mode to the second mode by receiving the personal code. Meanwhile, the mobile terminal 110 may periodically transmit a mode change request signal at a specific time to maintain the second mode, and receive a corresponding personal code.

On the other hand, the mobile terminal 110 in the first mode when calling (or requesting a call), the receiving number (that is, the number assigned to the receiving terminal 160 to form a communication line with the outgoing mobile terminal 110) A first outgoing call (or a first type of outgoing call) including Alternatively, the mobile terminal 110 may transmit a second outgoing call (or a second type of outgoing call) further including an additional signal requesting to change the calling number when calling in the second mode. For example, the second outgoing call may further include a caller number change request signal (or caller number change service request identifier, for example, #00#) for requesting change of the caller number. As another example, the second outgoing call may further include a user code for identifying the user or a personal code for verifying the outgoing call.

The authentication server 120 may be connected to the mobile terminal 110 through a mobile communication network (and/or network), and may generate a mode change permission signal for the mobile terminal 110 . Here, the mobile communication network may be a communication network established by the mobile communication system 130 .

In one embodiment, the authentication server 120 is installed in an institution, company, etc. to which the user using the mobile terminal 110 belongs, and the user's user information (name, affiliation, etc.) is stored in the database of the authentication server 120 . can The authentication server 120 sets the user's mission status information (eg, during a mission, non-work (off work, vacation, etc.)) and the user's mission location information (eg, dispatch location, fire location), The mission status information and the mission location information may be included in the user information. In addition, the user information may further include a user code (or user identifier) assigned to the user.

For example, if the user is a firefighter and the mission status is set to ON or OFF depending on going to work or leaving the office, or when an evacuation instruction occurs, the mission status is ON, and off when the mobilization is canceled. It can be set to (OFF). In addition, when the dispatch instruction occurs, the authentication server 120 may update the task location information of the user based on the task location (eg, fire location, rescue request location) included in the dispatch instruction.

The authentication server 120 may set the first area (or mission area) or the first path (or dispatch path) based on the mission location information of the user who has been dispatched (ie, the mission status is on). For example, the authentication server 120 may set an area within a certain distance (eg, 1Km) based on the mission location (eg, fire location) included in the mission location information as the first area. . For example, the authentication server 120 may set a movement path from the work place of the dispatcher to the mission location.

In an embodiment, the authentication server 120 may generate a mode switch permission signal based on the task status information of the user who has the mobile terminal 110 , the task location information, and the current location information of the mobile terminal 110 . have. Here, the current location information of the mobile terminal 110 may be periodically generated or updated from the mobile communication system 130 according to the user's consent to provide the location information, and from the mobile communication system 130 to the authentication server 120 . The current location information of the mobile terminal 110 may be provided periodically or when an event occurs (eg, when an outgoing call is generated).

For example, when the user's mission status is OFF, the authentication server 120 does not generate a mode switching permission signal due to "not in a mission status" or mode switching having an attribute value that disallows mode switching. A permit signal (or a mode change disallow signal) may be generated.

As another example, when the task state of the corresponding user is ON, the authentication server 120 determines that the mobile terminal 110 (or the corresponding user) is located within the first area based on the current location information of the mobile terminal 110 . It is determined whether the mobile terminal 110 is located or located on the first path, and when the mobile terminal 110 is located within the first area or located on the first path, the mode is switched (ie, the mode from the first mode to the second mode). to generate a mode switching permission signal that allows switching).

Accordingly, the authentication server 120 may prevent the user from arbitrarily abusing the caller ID change service regardless of the performance of the mission.

Meanwhile, although it has been described that the authentication server 120 directly generates the mode change permission signal, it is not limited thereto.

In another embodiment, the authentication server 120 may perform authentication for the mobile terminal 110 in response to the mode change request signal received from the mobile terminal 110, instead of directly generating the mode change permission signal. have. For example, the authentication server 120 may authenticate the user or the mobile terminal 110 by matching ID, PW, and terminal information included in the mode change request signal with pre-stored information.

The mode change request signal includes user information of a user who owns the mobile terminal 110 and location information of the mobile terminal 110, and the authentication server 120 performs authentication based on the user information, but Authentication may be performed based on the user's task status and location information of the mobile terminal 110 . The authentication server 120 may perform user authentication for the user based on user information, and if the user authentication is successfully performed, the authentication server 120 may perform authentication for the mobile terminal based on location information of the mobile terminal 110 . .

For example, when there is no user information matching the user information included in the mode change request signal, the authentication server 120 provides the mobile terminal 110 that user authentication has failed due to “no matching user information”. can do. As another example, the authentication server 120 may check user information, but when the user's mission state is OFF, the authentication server 120 may provide the mobile terminal 110 with a user authentication failure due to "not in a mission state". . As another example, when the task state of the corresponding user is ON, the authentication server 120 may provide the mobile terminal 110 that user authentication has been successful.

On the other hand, the authentication server 120, when authentication (ie, authentication for the user and/or the mobile terminal 110) is successfully performed, generates a personal code issuance request signal and transmits it to the mobile communication system 130, , it is possible to transmit (or transmit) 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 (ie, a number to be changed and used as a calling number).

On the other hand, the authentication server 120, when receiving an incoming call corresponding to the additional number from the receiving terminal 160, the mobile terminal 110 corresponding to the additional number (eg, the first mobile terminal 110a)) A request may be made to the mobile communication system 130 so that an incoming call is forwarded to the mobile terminal 110 (eg, the first mobile terminal 110a) based on the incoming call setting information of . In addition, when the receiving terminal 160 is not connected to the mobile terminal 110 within a specific time (eg, 5 seconds) from the point in time when the call forwarding for the incoming call is requested (eg, the first mobile terminal 110a )) does not receive a call from the receiving terminal 160), the authentication server 120 may request the mobile communication system 130 to cancel the call forwarding. That is, when a specific time has elapsed since an incoming call is received from the receiving terminal 160 , the call forwarding may be canceled and the authentication server 120 may be connected to the receiving terminal 160 . In addition, when a specific time (eg, 1 day) has elapsed from the time when the call setting information for the receiving terminal 160 is set or stored/updated, the authentication server 120 may initialize the corresponding call setting information. have. Accordingly, it is possible to prevent the reception terminal 160 from being connected to the mobile terminal 110 after the user's task is finished.

When the mobile communication system 130 (or the intelligent network system 133) receives the second incoming call including the calling number change request signal from the mobile terminal 110, based on the calling number change request signal, the mobile terminal The second incoming call corresponding to the second outgoing call may be transmitted to the receiving terminal 160 by searching for a preset additional number for 110 and changing the basic number for the mobile terminal 110 to the additional number.

Here, as shown in FIG. 1, the mobile communication system 130 includes a base station 131, a switching center 132, an intelligent network system 133, and the like, and the switching center 132 is connected to a public network (not shown). It is possible to provide a communication service to the mobile terminal 110 and the like. Since the specific configuration of the mobile communication system 130 is described in Korean Patent Publication No. 2006-0116500 (published on November 15, 2006) "Method and system for calling a mobile communication terminal using multiple numbers," the mobile communication system 130 ), a description of the basic configuration will be omitted.

The mobile communication system 130 may store caller numbers of the corresponding user. For example, the mobile communication system 130 may store the user's basic number as the first caller number and the additional number as the second caller number as user information. The mobile communication system 130 searches for a preset additional number for the mobile terminal 110 on the basis of the second incoming call (ie, the caller number change request signal), and sets the basic number for the mobile terminal 110 as the additional number. can be changed to That is, the mobile communication system 130 may transmit the second incoming call including the additional number to the receiving terminal 160 in response to the second outgoing call.

In another embodiment, the mobile communication system 130 (or the intelligent network system 133) may generate a personal code in response to a personal code issuance request signal. The personal code may be an authentication number or password used for the mobile terminal 110 to use the calling number change service.

The mobile communication system 130 provides a personal code based on the additional number included in the personal code issuance request signal and the location information of the mobile terminal 110 (or the location information of the base station 131 covering the mobile terminal 110). can create Here, the location information of the mobile terminal 110 is included in the personal code issuance request signal and provided from the authentication server 120 or covers the mobile terminal 110 (or forms a communication network directly with the mobile terminal 110 ) may be obtained through the base station 131. For example, the mobile communication system 130 may generate a personal code using a specific equation, a specific encryption algorithm, etc. That is, the mobile communication system 130 By generating a one-time location-based personal code, it is possible to prevent a user or other users from using the caller ID change service without permission.

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 caller number (ie, the pre-stored additional number) to send the second call. The number can be updated. That is, when the mobile communication system 130 receives an additional number different from the pre-stored second calling number, the mobile communication system 130 may determine that it is a request to update the additional number and update the second calling number.

When receiving the second outgoing call including the personal code from the mobile terminal 110, the mobile communication system 130 determines the validity of the second outgoing call based on the personal code included in the second outgoing call, and When the outgoing call is valid, the basic 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 point of the second outgoing call (or information of the base station 131 covering the mobile terminal 110) and the additional number, The personal code included in the second outgoing call is compared with the personal code for verification, and if the personal code matches the personal code for verification, the basic number is changed to an additional number and the outgoing call (that is, outgoing call) to the receiving terminal 160 Outgoing calls with changed numbers) can be transmitted. That is, as described above, when the personal code is generated as a location-based one-time code, the mobile communication system 130 may determine the validity based on the location attribute of the personal code received through the second outgoing call.

In an embodiment, the second outgoing call may further include a number change request signal and a second additional number. Here, the number change request signal is a code for requesting a change of the calling number, for example, may be a code having a preset format/size/length, such as "#00#". The second additional number may be a caller number that the user wants to change and use. In general, since the additional number is pre-stored in the authentication server 120 and the mobile communication system 130, there may be no need for a user to directly input and use the number. However, when each of a plurality of users uses a plurality of calling number change services, a large cost may be additionally required for storing additional numbers. Accordingly, the mobile communication system 130 may not separately store the additional number in a database or the like. In this case, the authentication server 120 receives the additional number from the user in the user authentication step, determines the validity of the additional number based on the user information (eg, the user belongs to the fire department, the representative number 119 of the fire department) can be used), and requests the mobile communication system 130 to generate/issuance of a personal code for a valid additional number, and the mobile communication system 130 generates a personal code in response to the personal code issuance request. can

Then, the mobile communication system 130, when receiving the second outgoing call from the mobile terminal 110, based on the number change request signal included in the second outgoing call, the personal code and the second addition from the second outgoing call By extracting the number, generating a personal code for verification based on the location attribute of the second outgoing call and the second additional number, and comparing the personal code for verification with the personal code included in the second outgoing call, whether the calling number has been changed can decide

For example, the second outgoing call for calling number change has a preset format, "number change request signal (eg #11#)" + personal code (eg, 4 digits)" + " It may be composed of an additional number (eg, #additional number#)” + “receiving number (eg, 7 to 11 digits).” Accordingly, the mobile communication system 130 receives the personal information from the second outgoing call. A code and a second additional number can be extracted.

Thereafter, the mobile communication system 130 forms a communication network directly with the mobile terminal 110 while covering the originating point of the second outgoing call (eg, location information of the mobile terminal 110 or the mobile terminal 110 ) By generating a personal code for verification based on the base station 131 (information of the base station 131) and the second additional number, the user determines whether the caller number change was made during the mission, and an available (or authenticated) additional number as the caller number. It can be determined whether or not to use

Referring to FIG. 3 , the mobile terminal 110 may operate in the second mode. As described with reference to FIG. 2A , the mobile terminal 110 operates in the second mode through a separate application or through a communication module 400 to be described later, for example, only by combining the communication module 400 . It can operate in 2 modes. In the second mode, the mobile terminal 110 may display a caller number change request icon together with a caller number input window requesting input of the caller number. When receiving a caller ID change request through the caller ID change request icon, the mobile terminal 110 may transmit a second outgoing call including a caller ID change request signal.

The mobile communication system 130 (or the intelligent network system 133) searches for a preset additional number for the mobile terminal 110 based on the calling number change request signal included in the second outgoing call, and the additional number is successfully , the basic number can be changed to an additional number (eg, "119"). Accordingly, the mobile communication system 130 may transmit the outgoing call to the receiving terminal 160 (eg, a mobile terminal owned by the owner of an illegally parked vehicle) using the additional number as the calling number. In particular, the mobile communication system 130 may specify a ringtone caused by an outgoing call as a specific ringtone (eg, siren bell and vibration).

In this case, the receiving terminal 160 displays the changed calling number, that is, the additional number together with the specified ringtone, so that the user of the receiving terminal 160 can easily recognize an emergency situation. That is, the reception rate of the mobile terminal 110 may be improved.

In another embodiment, when the second outgoing call includes a personal code, the mobile communication system 130 determines the suitability of the caller number change request using the personal code, and when the caller number change request is appropriate, sets the basic number as an additional number (eg, "119").

On the other hand, when a call connection is not made with the user of the receiving terminal 160 in the second mode (that is, when the recipient is absent), context information (eg, vehicle location information) is transferred to a person (eg, towed) company) can be transmitted.

For example, the mobile terminal 110 may enter a photo taking mode for message transmission at the same time as the call connection attempt is terminated. That is, the mobile terminal 110 executes/operates the camera provided in the mobile terminal 110 , and includes a photo of an object related to the receiving terminal 160 or information on the object (eg, the license plate number of an illegally parked vehicle). photos or video information) can be acquired. Thereafter, the mobile terminal 110 automatically generates a message using the location information (or GPS location information) obtained through the GPS module provided in the mobile terminal 110 and the picture of the object, and through a mobile communication network, etc. It can be transmitted to the authentication server 120 , the related institution server 140 , and the related terminal 150 . Here, the related institution server 140 obtains detailed information (eg, owner information) of the corresponding object in relation to the corresponding location (or GPS location information) or object (eg, illegally parked vehicle), or It may be a police station, a local government (eg, city hall, ward office), etc. that can perform a disposition (eg, as an administrative disposition, imposing demerit points on the object user, a fine for negligence, etc.) on the object. The related terminal 150 may be a towing company that can quickly process the object.

For example, the mobile terminal 110 transmits a message including location information and object information to the authentication server 120, and the authentication server 120 searches/determines a related organization based on the location information and the object information, , it requests/obtains relevant information (for example, contact information of the nearest towing company, contact information of the owner of illegally parked vehicles, etc.)

As described with reference to FIGS. 1 to 3 , the caller ID change system 100 checks the user's task status and the user's task location (or the location information of the mobile terminal 110 ) and sends it to the mobile terminal 110 . By allowing mode conversion (ie, mode conversion from the first mode to the second mode) for the user, it is possible to prevent the user from using the caller ID change service without permission outside of work (outside the work place).

In addition, the calling number change system 100 automatically generates a message including location information, object information (eg, vehicle number), etc. when a call or connection is not made with the receiving terminal 160, and related By disseminating it to institutions and related parties (eg, vehicle owners, towing companies, etc.), it is possible to more quickly handle the work related to the caller ID change service.

Furthermore, the calling number change system 100 may set whether the mobile terminal 110 receives an incoming call from the receiving terminal 160 , and allows the incoming call of the mobile terminal 110 to the receiving terminal 160 . You may.

Meanwhile, although it has been described that the mobile terminal 110 can use the calling number change service only in the second mode by using a separate application in FIGS. 1 to 3 , the present invention is not limited thereto. For example, the mobile terminal 110 may use the calling number change service using the communication module 400 , which will be described later with reference to FIG. 4 . As another example, even in the first mode, the mobile terminal 110 receives a number change request signal (or a caller number change service request identifier, for example #00#), a personal code (for example, 0000), and a received number. It is also possible to use the caller ID change service through direct input. This will be described later with reference to FIG. 5 .

4 is a diagram illustrating an example of a communication module of a mobile terminal included in the caller ID change system of FIG. 1 .

Referring to FIG. 4 , the communication module 400 may perform mode change (eg, change from a first mode to a second mode) of the mobile terminal. When the communication module 400 is mounted on the mobile terminal 110 instead of running the application described with reference to FIG. 2A , authentication for the mobile terminal 110 is automatically performed, and according to the authentication result, the mobile terminal 110 ) can operate in the second mode.

The communication module 400 may be detachably attached to the outside of the mobile terminal 110 (eg, a mobile phone for performing official duties). The communication module 400 may be manufactured in a size smaller than that of the mobile terminal 110 , and may be connected to the mobile terminal 110 through a connection jack 410 . On the other hand, the communication module 400 may be manufactured with an Ingress Protection (IP) 68. In this case, the communication module 400 may protect the internal circuit from dust and immersion occurring at the disaster site.

The communication module 400 may include a connection jack 410 , a decoder unit 420 , an encryption unit 430 , a processing unit 440 , and a battery 450 .

The connection jack 410 is formed to protrude to a specific length for insertion/connection into the external connection terminal 111 (or insertion hole) of the mobile terminal 110, and an additional number (ie, change) provided by the communication module 400 number to be used) may be provided to the mobile terminal 110 . For example, the connection jack 410 may be implemented as earphone jacks, and may be inserted or connected to the earphone connection terminal of the mobile terminal 110 .

The decoder unit 420 (or decoder chip) may identify SIM chip information included in the mobile terminal 110 . For example, the decoder unit 420 may obtain user information stored in the SIM chip, caller number information, and the like. The processing unit 440 to be described later may authenticate the mobile terminal 110 based on user information, caller ID 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 may encrypt data transmitted and received using the mobile communication system 130 .

The processing unit 440 (or main CPU) is configured to change and use the basic number (eg, a unique caller number given to the terminal of the official) of the mobile terminal and an additional number (i.e., a number to be changed through the caller number change service) ) can be matched.

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

Meanwhile, the processing unit 440 may perform user authentication based on user information, etc., and when the user authentication is successfully performed, may generate a personal code based on an additional number or the like.

According to an embodiment, the processing unit 440 may store a communication record (or a call record) generated during operation in the second mode. That is, the processing unit 440 may include a memory device.

For example, when the second outgoing call to the receiving terminal 160 is transmitted from the mobile terminal 110 , the processing unit 440 includes information on the origination time of the second outgoing call (ie, the originating time), the receiving terminal 160 . ) information (ie, recipient number) can be stored. In addition, when the mobile terminal 110 transmits a message to the receiving terminal 160 in the second mode, message information, that is, text and photos (including photographed location information) are stored in the processing unit 440 . can

In this case, only by mounting or connecting the communication module 400 to the other mobile terminal 110 (eg, the second mobile terminal 110b) or the manager terminal (not shown) (also, the other mobile terminal 110 ) when the entry into the second mode is successfully approved), the communication record in the second mode of the mobile terminal 110 can be checked. In terms of personal information, when a specific user (eg, a user using the first mobile terminal 110a) does not approve disclosure of his/her communication record, the institution to which the user belongs checks the user's communication record It can be difficult. In addition, if the disclosure of the user's communication record is comprehensively approved, the user's privacy may be infringed. Accordingly, by separately storing and managing the communication record made in connection with the task performance in the communication module 400, it is possible to facilitate the reading of the communication record of the authorized administrator, and the privacy of the user can be protected.

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 a calling number change service through the communication module 400 installed instead of the application. The communication module 400 may perform the same function as the application or independently perform user authentication, personal code issuance, and the like. Accordingly, a user using the mobile terminal 110 can easily use the calling number change service only by attaching (or detaching) the communication module 400 .

5 is a diagram illustrating an example of providing a caller number change service in the caller number change system of FIG. 1 .

1, 2A, and 5 , the first mobile terminal 110a transmits a first outgoing call including a caller number change request signal and a user code to the mobile communication system 130 in the first mode. can do.

For example, the first outgoing call is a caller number change request signal (or caller number change service request identifier, for example #00#), a user code (for example, 000000), a called number (for example, phone number of the receiving terminal 160). Here, the user code is a code for identifying the first user, and may correspond to the user ID of the first user.

For reference, in the second mode, a failure occurs in the data network transmitting the mode change request signal, an error occurs in the application providing the mode change, or a defect occurs in the user's mobile terminal in which the application is installed, see FIG. 4 Thus, a defect may occur in the communication module 400 described above. In this case, the user may not be able to use the caller ID change service in the second mode of the first mobile terminal 110a. Accordingly, the caller ID change system 100 may provide a caller ID change service even in the first mode of the first mobile terminal 110a.

The mobile communication system 130 searches for an additional number preset for the first mobile terminal 110a based on the terminal information of the first mobile terminal 110a in response to the caller number change request signal, but in particular, 1 If the mobile terminal 110a is not registered, the additional number may not be searched.

In this case, the mobile communication system 130 provides or transmits the user code received from the first mobile terminal 110a and the current location information of the first mobile terminal 110a to the authentication server 120 , and the first mobile terminal 110a. You can request authentication for (110a).

The authentication server 120 may extract first user information on the first user from the database based on the user code, and perform authentication on the first mobile terminal 110a based on the first user information.

For example, as described above, according to the first user information, the authentication server 120 determines that the first user is in a mission state, and is based on the current location information of the first mobile terminal 110a provided from the mobile communication system 130 . Accordingly, when the first mobile terminal 110a is located in the first area or the first route (ie, the area or route set based on the mission location information of the first user), the calling number of the first mobile terminal 110a is changed It can generate an authentication signal indicating that the request is legitimate. According to an embodiment, the authentication server 120 extracts a preset phone number corresponding to the first user from the first user information, and displays the terminal state in a mobile terminal (not shown) corresponding to the extracted phone number of the first user. You can send an outgoing call for confirmation. When it is confirmed that the mobile terminal is in a communication impossible state through the mobile communication system 130 or the like, the authentication server 120 may generate an authentication signal.

As another example, the authentication server 120 extracts a phone number from the extracted first user information, and determines whether the extracted phone number matches the basic number (ie, caller number) included in the first outgoing call, When the extracted phone number matches the basic number, it is possible to request transmission of a password corresponding to the user code to the first mobile terminal 110a. For example, the password may be the password PW described with reference to FIG. 2A . When receiving the password from the first mobile terminal 110a in response to the request, the authentication server 120 may perform user authentication for the first user using the first mobile terminal 110a based on the password. . That is, the authentication server 120 may additionally determine whether the party user has requested the change of the calling number.

As another example, when the first user is identified based on the user information corresponding to the user code, the authentication server 120 provides user information (ie, the second user) about the second user performing the same task as the first user from the database. 2 user information) can be extracted. The authentication server 120 transmits to the second mobile terminal 110b used by the second user a confirmation request signal for confirming whether the first user and the mission are being performed (that is, the state of the first user) (in other words, the second mobile terminal 110b). 1 requests approval for changing the number of the user), receives confirmation information for a confirmation request signal from the second mobile terminal 110b, and additionally performs user authentication for the first user based on the confirmation information . According to an embodiment, when the extracted phone number of the first user does not match the basic number, an outgoing call for checking the terminal status is transmitted to a mobile terminal (not shown) corresponding to the extracted phone number of the first user. may be When it is confirmed that the mobile terminal is in a communication impossible state through the mobile communication system 130, etc., the authentication server 120 receives user information (ie, the second user) about the second user performing the same task as the first user from the database. 2 user information), and transmits a confirmation request signal to the second mobile terminal 110b used by the second user for confirming whether a mission is being performed with the first user, and a confirmation request signal from the second mobile terminal 110b Receive confirmation information for , and user authentication for the first user may be performed based on the confirmation information.

In another embodiment, the authentication server 120 may transmit an outgoing call to the receiving terminal 160 in a three-way call method. For example, in the first mode, the first mobile terminal 110a may transmit a first outgoing call including a caller number change request signal and a user code to the authentication server 120 through the mobile communication system 130 . have. In this case, the authentication server 120 extracts first user information about the first user from the database based on the user code, and performs authentication on the first mobile terminal 110a based on the first user information, When authentication for the first mobile terminal 110a is successfully performed, an outgoing call may be transmitted to the receiving terminal 160 in a three-way call method. That is, a communication path may be formed between the first mobile terminal 110a, the authentication server 120 , and the reception terminal 160 . When a call connection is made between the first mobile terminal 110a and the receiving terminal 160 , the authentication server 120 may directly store the content of the call. Since there is a special circumstance that the first mobile terminal 110a requested to change the calling number in the first mode, the stored call contents may be used for the authentication server 120 to determine the special circumstance.

Similar to the call setup information described with reference to FIG. 2B , the first mobile terminal 110a transmits a first outgoing call further including call setup information (eg, *#1 located after the called number) through mobile communication. may be sent to the authentication server 120 via the system 130 .

In this case, the authentication server 120 may separately store the allowed incoming phone number of the first mobile terminal 110a. When receiving an incoming call corresponding to the additional number from the receiving terminal 160 corresponding to the incoming call allowed phone number, the authentication server 120 forwards the incoming call to the first mobile terminal 110a based on the call setup information. It may be requested from the mobile communication system 130 as much as possible.

As described with reference to FIG. 5 , the caller ID change system 100 may provide a caller ID change service even in the first mode of the first mobile terminal 110a.

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

Referring to FIGS. 1 and 6 , the method of FIG. 6 may be performed in the calling number change system 100 of FIG. 1 .

The authentication server 120 may set the user's mission status information (eg, during a mission, not working (office, vacation, etc.)) and the user's mission location information (eg, dispatch location, fire location). (S610).

For example, when an evacuation instruction occurs to a user using the mobile terminal 110 , the authentication server 120 determines the user based on the mission location (eg, fire occurrence location, rescue request location) included in the dispatch instruction. It is possible to update the mission status information and mission location information of The user's mission status information and mission location information may be stored in a database. The user's mission status information and mission location information may be updated when an event occurs (eg, when a dispatch mission occurs).

The authentication server 120 receives a mode switching permission signal for the mobile terminal 110 based on the task status information and task location information of the user who has the mobile terminal 110 and the current location information of the mobile terminal 110 . can create

In one embodiment, the authentication server 120 may periodically receive the current location information of the mobile terminal 110 from the mobile communication system 130 (S621). For example, when consent for transmission of the current location information of the mobile terminal 110 is preset, the mobile communication system 130 may periodically transmit the current location information of the mobile terminal 110 to the authentication server 120 . have.

The authentication server 120 determines whether the user's mission status information is a mission status and whether the mobile terminal 110 is located within a mission area (ie, a first area or a first path set based on the user's mission location information). It can be determined (S622).

When the user's mission status information is the mission status, and the mobile terminal 110 is located within the mission area (ie, the first area or first path set based on the user's mission location information), the authentication server 120 moves It is possible to generate a mode change permission signal that allows the mode change of the terminal 110 (ie, the mode change from the first mode to the second mode) ( S623 ).

The authentication server 120 transmits a mode change permission signal to the mobile terminal 110 (S624), and the mobile terminal 110 performs a mode change from the first mode to the second mode based on the mode change permission signal. It can be (S630). For example, when an application providing a caller ID change service is installed in the mobile terminal 110, the corresponding application may be activated. When the mobile terminal 110 operates in the second mode, the mobile terminal 110 may maintain the second mode.

The mode change permission signal may be updated whenever the user's task status changes, and may also be updated periodically based on current location information of the mobile terminal 110 . That is, even if a separate request for changing the calling number is not received from the mobile terminal 110 , the authentication server 120 may allow the mobile terminal 110 to operate in the second mode in which the calling number change is possible. Mode switching of the mobile terminal 110 may be allowed only when a request for changing the caller number is received from the mobile terminal 110, but in some cases, when receiving a caller number change request from a plurality of mobile terminals 110 , the mode switching of the mobile terminal 110 may not be smoothly performed. Accordingly, in the method of providing a caller number change service according to embodiments of the present invention, even if a caller number change request is not received from the mobile terminal 110 , the task status information and task location information of the user possessing the mobile terminal 110 . It is possible to allow the operation of the mobile terminal 110 in the second mode based on the

Meanwhile, in the second mode, the mobile terminal 110 may transmit a second outgoing call including a caller number change request signal to the mobile communication system 130 (S640).

In this case, the mobile communication system 130 searches for a preset additional number for the mobile terminal 110, changes the basic number of the mobile terminal 110 to the additional number (S650), and the additional number (that is, the changed caller) number) may be transmitted to the receiving terminal 160 (that is, an incoming call corresponding to the second outgoing call) (S660).

On the other hand, the mobile terminal 110 determines whether a reference time has elapsed after receiving the mode change permission signal (S670), and when the reference time has elapsed after receiving the mode change permission signal, the first mode in the first mode Mode conversion may be performed to the mode (S580). On the other hand, when receiving the mode change permission signal before the reference time elapses, the mobile terminal 110 may maintain the second mode. That is, the authentication server 120 periodically generates a mode change permission signal that allows the operation (or caller ID change) of the mobile terminal 110 in the second mode, and the mobile terminal 110 allows the mode change. If the signal is not received, the mobile terminal 110 may switch to the first mode.

When the mobile communication system 130 cannot allow the change of the caller number for the first mobile terminal 110a (eg, there is no additional number preset for the first mobile terminal 110a, or there is no caller number change request) If the signal is not an authenticated request signal), the mobile communication system 130 may request authentication for the first mobile terminal 110a from the authentication server 120 (S815). The mobile communication system 130 may transmit the user code received from the first mobile terminal 110a and the current location information of the first mobile terminal 110a to the authentication server 120 together with the authentication request.

The authentication server 120 may extract first user information about the first user from the database based on the user code (S820). According to an embodiment, the authentication server 120 may extract a phone number included in the first user information.

The authentication server 120 may authenticate the first mobile terminal 110a based on the extracted first user information. As described above, the authentication server 120 determines whether the mission status information of the first user is the mission status according to the first user information, and moves the first based on the current location information of the first mobile terminal 110a. It may be determined whether the terminal 110a is located within the mission area (ie, the first area or the first path described above) (S825).

When authentication for the first mobile terminal 110a (or the first user) is successfully performed, the authentication server 120 may generate an authentication signal for authenticating the first mobile terminal 110a (S840). .

Meanwhile, as described above, in the process of authenticating the first mobile terminal 110a, the authentication server 120 determines whether the extracted phone number matches the basic number (ie, caller number) included in the first outgoing call. , and if the extracted phone number matches the basic number, it requests transmission of a password corresponding to the user code to the first mobile terminal 110a, and receives the password from the first mobile terminal 110a in response to the request. User authentication for the first user who uses the first mobile terminal 110a may be performed based on the password.

In another embodiment, when the first user is identified based on the user information corresponding to the user code, the authentication server 120 receives user information (ie, the user information about the second user performing the same task as the first user from the database). second user information) may be extracted (S831).

The authentication server 120 sends a confirmation request signal to the second mobile terminal 110b (or a fellow mobile terminal) used by the second user to confirm whether the task is being performed with the first user (ie, the state of the first user). Transmitting (in other words, requesting approval for changing the number of the first user) (S832), and confirming information on the confirmation request signal from the second mobile terminal 110b (or the confirmation signal for changing the calling number) Upon receiving (S833), authentication for the first user (or the first mobile terminal 110a) may be additionally performed based on the confirmation information.

Meanwhile, the authentication server 120 may transmit an authentication signal for the first mobile terminal 110a to the mobile communication system 130 (S130). In this case, the mobile communication system 130 may convert the outgoing call transmitted from the first mobile terminal 110a based on the authentication signal into an incoming call in which the calling number has been changed and transmitted to the receiving terminal 160 .

According to an embodiment, the authentication signal may include a first basic number according to the first user information or a first additional number corresponding to the first basic number.
