Description

Method for providing safe number service sharing one virtual number, and communication relay device implementing the same

The present disclosure relates to a safety number service.

The safe number service or virtual number service is a service in which a virtual number is assigned so that the phone number of a wired/mobile phone is not exposed, and calls and text messages are received through the virtual number. The general safety number service is mainly provided as a receiver-protected one-way service that replaces the customer's phone number with a virtual number to protect customer's personal information. In this case, the caller who calls or texts the virtual number For example, the phone number of the delivery person) may be exposed to the recipient. In addition, when the receiver makes a reverse call to the sender, his/her own phone number is exposed as the calling number, and personal information may not be properly protected.

As a prior art, there is a method of allocating a virtual number to each user and exposing only the virtual number during a call between users. However, time and resources are required for assigning and managing virtual numbers and converting phone numbers to virtual numbers. In addition, since everyone is anonymized through the virtual number, if a customer receives a call or text with a virtual number as the originating number, it is difficult to know who sent the call or text, and the virtual number is considered as spam. It is conceivable, and the virtual number can be abused for sending spam or phishing crimes.

In the case of another prior art, there is a method in which a server assigns a customer phone number and a phone number of a courier delivery service provider to a virtual number based on a delivery item, and relays a call between the customer and the delivery service delivery service provider. However, since this method is only possible when the server clearly knows both parties using the virtual number, there is a limit in that it is difficult to use for a service that is difficult to apply when the other party is unspecified.

Devices constituting the network may be implemented as hardware, software, or a combination of hardware and software.

1 is a diagram schematically illustrating a method for providing a safe number service according to an embodiment.

Referring to FIG. 1 , the communication relay device 100 provides a call/message processing service for connecting a caller and a receiver by receiving a call/message sent from a calling terminal and forwarding the call/message to a receiving terminal. In this case, the communication relay device 100 may receive a voice/video call or message sent from the calling terminal and transfer the voice/video call or message to the receiving terminal.

In addition, the communication relay device 100 provides a safe number service that does not expose a subscriber's phone number by using a virtual number when processing a call/message. The communication relay apparatus 100 of the present disclosure, through one virtual number, not only the phone number of the user assigned the virtual number, but also the other party's phone that sends a call/message to the virtual number or receives a call/message from the virtual number. It provides a safe number service that does not even expose the number.

The communication relay device 100 is driven by at least one processor, and may have a hardware configuration capable of providing various functions for the present disclosure.

For descriptive purposes, the user to whom the virtual number is assigned is referred to as the virtual number's owner (simply referred to as "the owner"). The other party who is not the owner and sends a call/message to the virtual number or receives a call/message from the virtual number is called a sharer of the virtual number (simply referred to as “sharer”).

Depending on the type of application service using the virtual number, the owner may explicitly know or may not know the virtual number assigned to him or her. For example, a customer of a parking notification service may be assigned a virtual number and post the virtual number assigned to a vehicle. Alternatively, for example, in an e-commerce service such as an online shopping mall, a customer may not know a virtual number assigned to him or her. The virtual number assigned to the owner may be fixed or one-time.

It will be described that the communication relay device 100 connects a call between terminals or transmits a message, and provides a communication service between a terminal 200 of an owner of a virtual number and a terminal 300 of a sharer of a virtual number. The owner device 200 and the sharer device 300 may be a calling device or a receiving device.

Depending on the type of application service using the virtual number, the owner terminal 200 may be connected to the application server 400 and execute a loaded application to configure settings related to the virtual number. Then, the application server 400 may request settings related to the virtual number to the communication relay device 100 .

The communication relay device 100 stores virtual number mapping information 500 and provides a safe number service that shares one virtual number using the virtual number mapping information 500 .

The virtual number mapping information 500 indicates a field 510 in which a virtual number is recorded, two phone number fields 530 and 550 in which two phone numbers are recorded, and whether each phone number field is overwritten. It may be composed of overwrite indicator (flag) fields 531 and 551, timer fields 532 and 552 for calculating the valid time of the phone number recorded in the phone number field, and caller ID fields 533 and 553. there is. The timer fields 532 and 552 and the caller ID fields 533 and 553 may be optional fields that can be used according to the type of application service using the virtual number or the setting of the owner. Meanwhile, the timer fields 532 and 552 and the caller ID fields 533 and 553 are described as being set for each phone number, but may be set only for the phone number 2 field among the two phone number fields. Alternatively, one timer or one caller identification phrase may be set for one virtual number.

In the overwrite indicator fields 531 and 551, 0 or 1 may be recorded. If the value is 0, overwriting of the corresponding phone number field is prohibited, and if the value is 1, overwriting of the corresponding phone number field is prohibited. may indicate permission.

In the timer fields 532 and 552, when a phone number is written in a phone number field having an overwrite indicator field of 1, a timer starts. When the timer expires, the communication relay device 100 deletes the phone number recorded in the phone number field. The effective time of the phone number recorded in the phone number field may be determined according to the type of application service using the virtual number or the setting of the owner.

In the sender display text fields 533 and 553, call information displayed to the receiver may be recorded. The caller ID phrase may be determined according to the type of application service using the virtual number or the setting of the owner. For example, when the application service is a parking notification service, the owner's phone number is written in the phone number field 1 (530), and phrases such as "parking notification" or "vehicle number oooo" are displayed in the caller ID field (533). can be recorded in In the other caller identification text field 553, a phrase such as “a person who shares the safety number” may be recorded. For another example, when the application service is an e-commerce service, the owner's phone number is recorded in the phone number field 1 530, and purchased product information (eg, product code, product name, etc.) is stored in the caller ID field 533. Phrases that can identify me or the buyer may be recorded. In another sender display field 553, information related to business procedures or business personnel, such as ooo shopping mall, ooo courier company, ooo delivery driver, and ooo product delivery, may be recorded.

Next, a method for the communication relay device 100 to manage the virtual number mapping information 500 will be described.

2 and 3 are flowcharts of a method for providing a safe number service according to an embodiment.

Referring to FIGS. 2 and 3 , it is assumed that the virtual number owner terminal 200 is a subscriber of the phone number 010-1111-1111 and owns the virtual number 9999-9999. It is assumed that the sharer terminal 300 of the virtual number is a subscriber of the phone number 010-2222-2222.

First, referring to FIG. 2 , the communication relay device 100 manages virtual number mapping information including virtual numbers 9999-9999 and owner phone numbers 010-1111-1111 connected thereto (S110). As shown in Table 1, the virtual number mapping information records a virtual number and two phone numbers linked to the virtual number. Initially, only the owner's phone number can be recorded in the phone number 1 field. At this time, since the owner's phone number is not a field that is changed, the overwrite indicator 1 of phone number 1 is 0 and the overwrite indicator 2 of phone number 2, which is empty, can be recorded as 1. In addition, the virtual number mapping information may further include a caller ID phrase (eg, parking notice).

virtual number phone number 1 overwrite
identifier1 phone number 2 overwrite
identifier2 9999-9999 010-1111-1111 0 Blank One

The sharer terminal 300 sends a call/message whose received numbers are virtual numbers 9999-9999 (S120). In this case, the originating number of the call/message is the phone number of the sharer terminal 300 010-2222-2222, and the received number is the virtual number 9999-9999.

Since the virtual number 9999-9999 is included in the received call/message, the communication relay device 100 checks the virtual number mapping information and records the originating number 010-2222-2222 of the call/message in the virtual number mapping information. Since there is no overwrite indicator, the calling number 010-2222-2222 is recorded in the phone number 2 field having an overwrite indicator of 1 (overwrite allowed) (S130). As shown in Table 2, the communication relay device 100 updates virtual number mapping information. The communication relay device 100 may manage the effective time of the phone number recorded in the phone number 2 field by driving a timer applied to the phone number 2 field. If the overwrite indicator of the phone number 2 field is 0 (overwrite prohibited), the communication relay device 100 may transmit a call connection failure/message transmission failure to the terminal that originated the call/message.

virtual number phone number 1 overwrite
identifier1 phone number 2 overwrite
identifier2 timer 9999-9999 010-1111-1111 0 010-2222-2222 One valid time

The communication relay device 100 extracts 010-1111-1111 of the phone number 1 field, changes the calling number from 010-2222-2222 to the virtual number 9999-9999, and the owner terminal whose received number is 010-1111-1111. In step 200, the call/message of the sharer terminal 300 is transmitted (S132). The communication relay device 100 transmits a call/message in which the originating number is virtual number 9999-9999 and the received number is 010-1111-1111. The communication relay device 100 may send a call/message by further including virtual numbers 9999-9999 or a caller ID related to the phone number 2 field (eg, parking notice).

The owner terminal 200 displays a call/message whose originating number is virtual number 9999-9999 (S140). At this time, when the call/message includes a caller identification phrase (eg, parking notice), the owner terminal 200 transmits the caller identification phrase (eg, parking notice) together with virtual numbers 9999-9999, or virtual numbers 9999-9999. Numbers 9999-9999 may be indicated instead.

Subsequently, when the owner wants to make a reverse call to the sharer who originated the call/message, the owner terminal 200 sends a call/message in which virtual numbers 9999-9999 are received numbers (S150). At this time, the calling number of the call/message is the phone number of the owner terminal 200 010-1111-1111, and the receiving number is the virtual number 9999-9999.

Since the received signal/message includes the virtual number, the communication relay device 100 checks the virtual number mapping information, and since the originating number 010-1111-1111 of the call/message is recorded in the phone number 1 field, The phone number 010-2222-2222 of the phone number 2 field is extracted (S160).

The communication relay device 100 changes the outgoing number to the virtual number 9999-9999, and transmits the call/message of the owner terminal 200 to the extracted phone number 010-2222-2222 (S162). The communication relay device 100 transmits a call/message in which the calling number is virtual number 9999-9999 and the receiving number is 010-2222-2222.

The sharer terminal 300 displays a call/message whose originating number is virtual number 9999-9999 (S170).

Then, when the timer of the phone number 2 field expires, the communication relay device 100 deletes the phone number recorded in the phone number 2 field (S180). Then, in the virtual number mapping information, as shown in Table 1, the phone number 2 field is updated with an empty value.

In this way, the two terminals communicate via the virtual number, but if, before the timer in the phone number 2 field expires, another terminal (not shown) with the phone number 010-3333-3333 calls/ When sending a message, the communication relay device 100 may overwrite the phone number 010-3333-3333 in the phone number 2 field having an overwrite indicator of 1 in the same manner as steps S130 to S132. That is, the communication relay device 100 checks the virtual number mapping information, records the calling number 010-3333-3333 in the phone number 2 field having an overwrite indicator of 1, and then changes the calling number to the virtual number 9999-9999. , a call/message of the sharer terminal 300 may be transmitted to the owner terminal 200 of virtual numbers 9999-9999.

Alternatively, before the timer in the phone number 2 field expires, if another terminal (not shown) with the phone number 010-3333-3333 sends a call/message to the virtual number 9999-9999, the communication relay device 100 A new phone number may not be overwritten until the timer in the number 2 field expires. In this case, the communication relay device 100 may respond to the terminal of the phone number 010-3333-3333 as busy or request redial after a certain time.

Referring to FIG. 3 , the communication relay device 100 receives two phone numbers mapped to virtual numbers from the application server 400 (S210). For example, the application server 400 may be a server that provides a designated driver service, and the two phone numbers may be phone numbers of a customer and a designated driver. Meanwhile, when the application server 400 is a server providing an e-commerce service, the other party to communicate with the owner may vary for each business procedure. In this case, when a business procedure is changed, the application server 400 may transmit phone numbers of customers and business managers mapped to virtual numbers to the communication relay device 100 .

The communication relay device 100 manages virtual number mapping information including virtual numbers 9999-9999 and two telephone numbers 010-1111-1111 and 010-2222-2222 connected thereto (S212). As shown in Table 3, the virtual number mapping information records a virtual number and two phone numbers connected to the virtual number. Since the two phone numbers are already mapped, the overwrite indicators can be set to 0. In addition, the virtual number mapping information may further include a caller ID phrase (eg, chauffeur service).

virtual number phone number 1 overwrite
identifier1 phone number 2 overwrite
identifier2 9999-9999 010-1111-1111 0 010-2222-2222 0

The sharer terminal 300 sends a call/message whose received numbers are virtual numbers 9999-9999 (S220). In this case, the originating number of the call/message is the phone number of the sharer terminal 300 010-2222-2222, and the received number is the virtual number 9999-9999.

Since the virtual number 9999-9999 is included in the call/message, the communication relay device 100 checks the virtual number mapping information, and since the originating number 010-2222-2222 of the call/message is recorded in the virtual number mapping information, The phone number 010-1111-1111 recorded in the other phone number field is extracted (S230).

The communication relay device 100 changes the calling number to the virtual number 9999-9999, and transmits the call/message of the sharer terminal 300 to the extracted 010-1111-1111 (S232). The communication relay device 100 transmits a call/message in which the calling number is virtual number 9999-9999 and the receiving number is 010-2222-2222.

The owner terminal 200 displays a call/message whose originating number is virtual number 9999-9999 (S240). At this time, when the received call/message includes a caller identification phrase (eg, chauffeur driving), the owner terminal 200 sends the caller identification phrase (eg, chauffeur driving) along with virtual numbers 9999-9999, Alternatively, virtual numbers 9999-9999 may be displayed instead.

Then, when the owner wants to make a reverse call to the sharer who originated the call/message, the owner terminal 200 sends a call/message in which virtual numbers 9999-9999 are received numbers (S250). At this time, the calling number of the call/message is the phone number of the owner terminal 200 010-1111-1111, and the receiving number is the virtual number 9999-9999.

Since the virtual number 9999-9999 is included in the call/message, the communication relay device 100 checks the virtual number mapping information, and since the originating number 010-1111-1111 of the call/message is recorded in the phone number 1 field, The phone number 010-2222-2222 of the phone number 2 field is extracted (S260).

The communication relay device 100 changes the outgoing number to the virtual number 9999-9999, and transmits the call/message of the owner terminal 200 to the extracted phone number 010-2222-2222 (S262). The communication relay device 100 transmits a call/message in which the calling number is virtual number 9999-9999 and the receiving number is 010-2222-2222.

The sharer terminal 300 displays a call/message whose originating number is virtual number 9999-9999 (S270).

The communication relay device 100 deletes the virtual number mapping information when receiving completion of use of the virtual numbers 9999-9999 from the application server 400 or when the valid time of the virtual numbers 9999-9999 has elapsed (S280).

Referring to FIG. 4 , the application server 400a providing a parking notification service receives setting information such as an effective time of a timer and a caller ID message from a customer terminal to which a virtual number is assigned (S310). Customers of the parking reminder service can post the assigned virtual number on the vehicle.

The application server 400a transmits virtual number mapping information including setting information such as a customer phone number, a virtual number, and an effective time/caller ID phrase to the communication relay device 100 (S312).

The communication relay device 100 stores virtual number mapping information including a virtual number and a customer's phone number, and sets overwrite permission in an empty phone number field connected to the virtual number (S320).

The communication relay device 100 receives a call/message whose reception number is a virtual number (S330). In this case, the originating number of the call/message is a phone number of an arbitrary terminal, and the received number is a virtual number.

The communication relay device 100 checks the virtual number mapping information of the virtual number included in the call/message, and since the originating number of the call/message is not recorded in the virtual number mapping information, it sends an outgoing call to the overwrite-allowed phone number field. Record the number (S340). The communication relay device 100 may manage the valid time of the recorded phone number by driving a timer in the overwrite permitted phone number field.

The communication relay device 100 sends a call/message to the customer's phone number by changing the calling number to a virtual number (S342). The communication relay device 100 may send a call by further including a sender display phrase (eg, parking notification). When the customer's terminal displays a call/message whose calling number is a virtual number, the customer can make a call with the other party or check a message sent by the other party.

Thereafter, the communication relay device 100 receives a call/message in which the customer's phone number is the calling number and the virtual number is the called number (S350).

The communication relay device 100 checks the virtual number mapping information of the virtual number included in the call/message, and since the calling number of the call/message is recorded as the customer's phone number, the phone number of the other phone number field linked to the virtual number Extract (S360)

The communication relay device 100 changes the calling number to a virtual number and sends a call/message to the extracted phone number (S362). Then, any terminal that has sent a call/message to the customer terminal displays the call/message sent from the virtual number, and the other party can make a call with the customer or check the message transmitted by the customer.

Thereafter, the communication relay device 100 deletes the phone number recorded in the overwrite-allowed phone number field after a certain period of time when the phone number is recorded in the overwrite-allowed phone number field (S370). Through this, the customer can receive a call/message from a new counterpart while using the assigned virtual number as it is.

Referring to FIG. 5 , the application server 400b providing the designated driver service transmits a virtual number to the customer terminal and the designated driver terminal (S410). At this time, the virtual number may be used once.

The application server 400b transmits virtual number mapping information including setting information such as virtual number, customer phone number, surrogate driver phone number, valid time/caller ID phrase to the communication relay device 100 (S412). .

The communication relay device 100 stores virtual number mapping information during the effective time of the virtual number (S420). The effective time of the virtual number may be set as a basic time or as a specific time considering service completion time. Alternatively, the communication relay device 100 may delete the virtual number mapping information when receiving the virtual number use completion from the application server 400b.

The communication relay device 100 receives a call/message whose reception number is a virtual number (S430).

The communication relay apparatus 100 checks the virtual number mapping information of the virtual number included in the call/message, and determines whether the originating number of the call/message is recorded in the virtual number mapping information (S440).

If the originating number of the call/message is recorded in the virtual number mapping information, the communication relay device 100 extracts the phone number of the other phone number field connected to the virtual number (S442).

The communication relay device 100 changes the calling number to a virtual number and sends a call/message to the extracted phone number (S444).

If the originating number of the call/message is not recorded in the virtual number mapping information, the communication relay device 100 transmits a call connection failure/message transmission failure to the originating number (S450). That is, if the originating number of the call/message is not recorded in the virtual number mapping information, this is because the call/message is not originating from the customer or proxy driver mapped to the virtual number.

Referring to FIG. 6 , when a customer purchases a product, the application server 400c providing e-commerce service provides additional setting information such as virtual number, customer phone number, business person in charge phone number, valid time/caller ID, etc. The included virtual number mapping information is delivered to the communication relay device 100 (S510). In this case, the application server 400c may deliver the virtual number mapped to the purchased product to the terminal in charge of the task. The application server 400c may set purchase product information (eg, product code, product name, etc.) or a phrase for identifying a purchaser in the sender display phrase of the virtual number.

The communication relay device 100 stores virtual number mapping information (S520).

At this time, if the business process for the customer's purchase is changed to the purchase confirmation step, delivery step, etc., the phone number of the person in charge of the business must be changed, so the application server 400c relays the renewal of the phone number mapped to the virtual number A request can be made to the device 100 (S530).

The communication relay device 100 updates virtual number mapping information (S540).

Thereafter, the communication relay device 100 receives a call/message whose reception number is a virtual number (S550). When a business person in charge sends a call/message to a customer, the call/message whose received number is a virtual number can be sent. Alternatively, when a customer sends a call/message to a person in charge, a call/message whose received number is a virtual number may be sent.

The communication relay apparatus 100 checks the virtual number mapping information of the virtual number included in the call/message, and determines whether the originating number of the call/message is recorded in the virtual number mapping information (S560).

If the originating number of the call/message is recorded in the virtual number mapping information, the communication relay device 100 extracts the phone number of the other phone number field connected to the virtual number (S562).

The communication relay device 100 changes the calling number to a virtual number and sends a call/message to the extracted phone number (S564). The communication relay device 100 may transmit a call/message of a business manager to a customer mapped to a virtual number or a customer call/message to a business manager mapped to a virtual number.

If the originating number of the call/message is not recorded in the virtual number mapping information, the communication relay device 100 transmits a call connection failure/message transmission failure to the originating number (S570). That is, if the origination number of the call/message is not recorded in the virtual number mapping information, this is because the call/message is not originating from the customer and business manager mapped to the virtual number.

As such, according to the present disclosure, it is possible to transfer a call/message between a caller and a receiver without exposing the phone numbers of the caller and receiver through one virtual number.

According to the present disclosure, not only can two phone numbers be connected to a virtual number, but an overwrite indicator and timer can be set in a phone number field, so that a safe number service can be applied according to the characteristics of various application services.

The embodiments of the present disclosure described above are not implemented only through devices and methods, and may be implemented through a program that realizes functions corresponding to the configuration of the embodiments of the present disclosure or a recording medium on which the program is recorded.
