Description of the Related Art In recent years, it has become common for people to have at least one mobile communication terminal, and calls for various purposes using such mobile communication terminals are frequently performed. For example, in a corporation or an organization, a telemarketing team for advertisement or publicity is placed and a call intended for advertisement or promotion is made to a current customer or a potential customer's mobile communication terminal.

When people receive a call from an unspecified person who is not stored in a phone book in the mobile communication terminal, they can not receive it because they do not know who the person is from, and feel uncomfortable when they receive an unwanted advertisement or publicity .

To solve this problem, a caller information display service has appeared.

The caller information display service is a service for displaying a caller's pre-designated phrase (for example, an OO bank sales department) on the mobile terminal when the caller terminal tries to make a call from the calling terminal to the mobile communication terminal, Is a service that allows you to recognize who is calling from.

As described above, when providing a caller information display service that displays a phrase (for example, an OO bank sales department) pre-designated by the calling terminal side on the mobile communication terminal of the called party, only a desired phone can be received from a user who receives the call Therefore, the aforementioned existing problems can be solved naturally.

However, the current caller information display service can be provided only for the communication line associated with the mobile communication company.

This is because the present method of providing the caller information display service is implemented in a way that is achieved only when the cooperation between the communication terminal on the calling terminal side and the mobile communication terminal on the called side is premised.

Accordingly, in the present invention, a method of providing a caller information display service to a calling terminal on a communication company side that is not affiliated with a mobile communication company is proposed.

Preferably, the display object confirmation unit confirms that the calling terminal is a caller information display object when the calling number is registered in the caller information display object DB, based on the sender information display object DB, The DB may be different from the subscriber DB based on the specific relay apparatus.

According to a second aspect of the present invention, there is provided a method of operating a call switching system, the method comprising: receiving an origination request from an originating terminal; A display object checking step of checking whether the calling terminal is a caller information display object, based on a calling number confirmed in the calling request; A first transmission step of, when the calling terminal is not the caller information display target, transmitting the calling request to a specific network device without changing; And a second transmission step of, when the calling terminal is the caller information display target, changing a setting for setting a subscriber identifier indicating a caller information display destination in a specific field of the origination request, and then transmitting the change to the specific network device.

Preferably, the origination request of the originating terminal is received from the originating terminal through a specific relay device, and the specific field is a device, when the specific relay device is a device associated with the specific network device for displaying caller information, The specific relay apparatus may be a field designated to set a subscriber identifier or a non-subscriber identifier for determining whether the calling terminal is a subscriber terminal for displaying caller information based on the subscriber DB.

Thus, according to the call exchange apparatus and the call exchange apparatus operating method of the present invention, it is possible to provide a caller information display service even for a call attempted at a terminal of a communication company that is not affiliated with a mobile communication company, .

1 is an exemplary diagram showing a system including a call switching apparatus according to a preferred embodiment of the present invention.
2 is an exemplary diagram illustrating a configuration of a call switching apparatus according to a preferred embodiment of the present invention.
3 is a flowchart illustrating an operation method of a call switching apparatus according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

First, a system including a call switching apparatus according to a preferred embodiment of the present invention will be described with reference to FIG.

The system including the call switching apparatus of the present invention is related to the background in which the terminal attempts to communicate with another terminal. Here, the calling party is the calling terminal and the receiving party is the calling party, and the system including the call exchange apparatus of the present invention is particularly related to the case where the called terminal is the mobile communication terminal.

Hereinafter, for convenience of explanation, it is assumed that the terminal 1 shown in FIG. 1 is the calling terminal and the terminal 2 is the called terminal.

1, the system including the call switching apparatus of the present invention includes a terminal 1, a terminal 2, a relay apparatus 10 operated by a calling terminal, that is, a communication company to which the terminal 1 is subscribed, 2, a call switching apparatus 100, 200, and a network apparatus 300 operated by a mobile communication company.

At this time, the communication company to which the terminal 1 is subscribed may be a mobile communication company or a wired communication company.

Generally, if the calling terminal, that is, the terminal 1 tries to make a call to the called terminal, i.e., the terminal 2, if the telephone number of the terminal 1 is not stored in the telephone directory of the terminal 2, You will not be forced to accept it, and you will feel uncomfortable if you do not want an advertisement or promotion.

By displaying the caller information (for example, the OO bank sales department) previously designated by the terminal 1 in the case of attempting to make a call, i.e., call from the caller terminal, that is, the terminal 1 to the called terminal, i.e., the terminal 2, A caller information display service that allows the user to know who the caller is from.

However, the current caller information display service can be provided only to the communication terminal line associated with the terminal 2, that is, the mobile communication company to which the called terminal is subscribed. That is, currently, the caller information display service described above can be provided only for a call attempted at a terminal associated with a mobile communication company of the called terminal.

This is because the present method of providing the caller information display service is implemented in a manner that is achieved only when cooperation between the communication terminal of the calling terminal and the mobile communication terminal of the called terminal is assumed.

Hereinafter, a method of providing a caller information display service will be briefly described with reference to FIG. In addition, for convenience of explanation, it will be described by way of example that the terminal 1 is a terminal subscribed to a cable communication company.

For example, when the terminal 1 attempts to make a call or a call to the terminal 2, a call request of the terminal 1 is transmitted to the call exchanger 100 (100) of the mobile communication company to which the terminal 2 is subscribed via the relay apparatus 10 of the wired communication company to which the terminal 1 is subscribed ).

Here, the origination request of the terminal 1 transmitted from the relay apparatus 10 to the call switching apparatus 100 includes the originating number, that is, the telephone number of the terminal 1 and the called number, that is, the telephone number of the terminal 2. Further, May also be included.

At this time, if the wired communication company to which the terminal 1 is subscribed is pre-associated with the mobile communication company of the terminal 2 for the caller information display service, the relay apparatus 10 of the wired communication company transmits the caller information to the terminal 1 based on the subscriber DB (For example, 1) and an unused identifier (for example, 0) according to the determination result to the call switching device 100 in a specific field designated in the origination request of the terminal 1. [

In this case, the origination request conforms to the ISDN User Part_Initial Address Message (ISUP_IAM) standard, and a specific field in the origination request may be an LTR bit in User to User Information (UUI) information included in the ISUP_IAM.

The subscriber DB used in the relay apparatus 10 is a DB for storing information of subscription terminals subscribed through a subscription procedure for a caller information display service among a plurality of terminals subscribed to a wired communication company including the terminal 1, It is managed by a communication company.

That is, when the terminal 1 is a subscriber terminal for displaying caller information, the relay device 10 of the wireline communication company that is pre-associated with the mobile communication company transmits a subscription identifier (e.g., 1). If the terminal 1 is not a subscriber terminal for displaying caller information, it sets an unused identifier (for example, 0) in a specific field in the originating request of the terminal 1, for example, the LTR bit in the UUI information, ). ≪ / RTI >

On the other hand, if the wired communication company to which the terminal 1 is subscribed is not affiliated with the mobile communication company of the terminal 2, that is, if it is not affiliated, the relay apparatus 10 of the wired communication company that is not affiliated with the mobile communication company, (E.g., 0) or a blank in the LTR bits in the UUI information, for example, to the call switching apparatus 100. [

Accordingly, the call exchange apparatus 100 of the mobile communication company transmits the origination request of the terminal 1 received through the relay apparatus 10 to the network apparatus 300, and confirms the location where the destination terminal is connected, that is, And confirms the called party's call exchange apparatus 200 connected to the called terminal, that is, the terminal 2 from the network device 300 and connects the call between the terminal 1 and the terminal 2 in cooperation with the checked incoming call exchange apparatus 200 And performs the conventional general call connection procedure.

At this time, the network device 300 corresponds to a home location register (HLR) that stores / manages terminal information, service subscription information, location information, and the like of each terminal subscribed to a mobile communication company.

Here, while the call connection procedure as described above is being performed, the caller information display service for the calling terminal, i.e., the terminal 1, may be provided by the network device 300. [

That is, the network device 300 checks whether a subscription identifier (e.g., 1) is set in a specific field in the origination request of the terminal 1, and when the subscription identifier (e.g., 1) For example, the OO bank sales department, from the TIIS (Telephony & IP Integration System) 400 and provides to the called terminal, i.e., the terminal 2 via the called party call exchange apparatus 200, Make it possible to display caller information (for example, OO Bank Sales).

At this time, the TIIS 400 interworks with a legacy server (not shown) performing a function of subscribing / changing / inquiring / deleting the supplementary service to transmit pre-registered sender information (for example, And the like). When the caller information acquisition of the terminal 1 is requested from the network device 300 as described above, the server 1 stores the origination number included in the origination request of the terminal 1, the subscription identifier of the specific field in the origination request (For example, OO bank sales department) registered in correspondence with the terminal 1 after the authentication using the business ID and the like can be provided to the network device 300. [

On the other hand, when the subscription identifier (for example, 1) is not set in the specific field in the origination request of the terminal 1, the network device 300 can not access the relay device 10 (For example, 0) is set in a specific field by the relay device 10, or because the wired communication company operating the relay device 10 is not affiliated with the mobile communication company for the caller information display service, (E.g., 0) or blank is set in the field, the caller information display service for the terminal 1 is not provided.

Hereinafter, a more specific example will be described. A message requesting the calling party's call exchange apparatus confirmation by providing a call request of the terminal 1 from the call switching apparatus 100 to the network apparatus 300 is called a Location Request message. In the Location Request message, when the originating request (for example, the origination request of the terminal 1) is originated to the called terminal or the originating terminal is in the middle of communication with another terminal, , An additional field may be specified. This additional field may be the LTR bit in the P_SFI (PCS_Service Features Indicator) information of the Location Request message.

The call switching apparatus 100 transmits the transmission request of the terminal 1 received through the relay apparatus 10 to the network apparatus 300 as described above to check the location to which the called terminal is connected, that is, In the requesting process, when the call is originated to the called terminal or the calling terminal is in communication with another terminal, an unused identifier (for example, 0) can be set in the LTR bit in the P_SFI, (E.g., 1) can be set in the LTR bit in the P_SFI when the call is not originated to the called terminal while it is in the call with the other terminal.

In this case, while the call connection procedure between the terminal 1 and the terminal 2 is performed as described above, the network device 300 sets a subscription identifier (e.g., 1) in a specific field in the origination request of the terminal 1, (For example, the OO bank sales department) of the terminal 1 from the TIIS 400 when the subscription identifier (e.g., 1) is set in the LTR bit in the P_SFI, The terminal 2 can display the caller information of the terminal 1 (for example, the OO bank sales department) while the terminal 2 is ringing.

On the other hand, even if a subscription identifier (for example, 1) is set in a specific field in a call request of the terminal 1 while the call connection procedure between the terminal 1 and the terminal 2 is performed as described above, If the subscription identifier (e.g., 1) is not set in the LTR bit in the P_SFI, the caller information display service for the terminal 1 may not be provided.

As described above, the present method of providing the caller information display service is implemented in a manner that is accomplished only when the cooperation between the originating terminal, that is, the wired communication company of the terminal 1 and the mobile communication terminal of the terminal 2, is assumed.

As a result, the current method of providing the caller information display service for a terminal of a communication company (for example, the communication company 1) that has not established an affiliation for a caller information display service is a method in which the communication company 1 establishes an affiliation with a mobile communication company Only.

When the communication company 1 establishes an affiliation with a mobile communication company to provide a caller information display service, it is determined whether or not the calling terminal is a subscriber terminal for displaying caller information and a subscriber identifier (e.g., 1) is set in a specific field in the calling request It is necessary to change the existing network of the communication company 1, that is, the existing relay apparatus.

Accordingly, in the present invention, a call exchanger device for providing a caller information display service for a call attempted at a terminal of a communication company that is not affiliated with a mobile communication company while minimizing an existing network change is provided. Specifically, I want to.

Hereinafter, the configuration of a call switching apparatus according to a preferred embodiment of the present invention will be described in detail with reference to FIG.

For convenience of explanation, the call exchange apparatus 100 on the call side of the call exchange apparatuses 100 and 200 shown in FIG. 1 will be described.

The call switching apparatus 100 according to the present invention includes a call origination request receiving unit 110 for receiving a call origination request from an originating terminal and a call origination number determination unit for determining whether the call origination terminal is a caller information display target, And a transmission unit for transmitting the origination request to a specific network device without changing the origination request when the originating terminal is not the caller information display object, To the specific network device after changing the subscriber identifier indicating the sender information display destination.

The originating request receiving unit 110 receives an origination request of the originating terminal.

For example, if the terminal 1 is a calling terminal and the terminal 2 is a called terminal as described above, if the terminal 1 attempts to make a call to the terminal 2, i.e., to make a call, To the call exchange apparatus 100 of the mobile communication company to which the terminal 2 is subscribed via the relay apparatus 10 of the communication company (e.g., wire communication company).

The originating request receiving unit 110 receives the originating request of the terminal 1 transmitted from the originating terminal, that is, the terminal 1 through the relay apparatus 10 of the wired communication company to which the specific relay apparatus, that is, the terminal 1 is subscribed.

The display object confirmation unit 120 determines whether the calling terminal, i.e., the terminal 1 is the caller information display object, based on the calling number confirmed in the received calling request.

For example, the display object confirmation unit 120 can confirm that the calling terminal, that is, the terminal 1 is the caller information display object when the calling number is registered in the caller information display object DB based on the sender information display object DB.

At this time, the sender information display target DB is different from the aforementioned subscriber DB based on the relay apparatus 10 of the wired communication company to which the specific relay apparatus, for example, the terminal 1 is subscribed.

More specifically, as described above, the subscriber DB used in the relay apparatus 10 is a subscriber DB used in the subscriber terminal 1 through a subscription procedure for a caller information display service among a plurality of terminals subscribed to a wired communication company, It is a DB in which information is stored, and is managed by a cable communication company.

However, as a result, since the subject providing the caller information display service is a mobile communication company, in order to realize the present invention, the mobile communication company can display caller information The information of the registered terminals registered through the registration procedure for the registered terminals can be DB and stored and managed. The DB stored and managed as described above can be referred to as a sender information display target DB.

When the calling request is received from the calling terminal, i.e., the terminal 1 through the calling request receiving unit 110, the display target identifying unit 120 checks the calling number in the received calling request, When the telephone number of the terminal 1 is not registered in the sender information display object DB, the terminal 1 is determined not to be the caller information display object Can be confirmed.

When the calling terminal, that is, the terminal 1 is not the caller information display destination, the originating request processing unit 130 transmits the originating request of the terminal 1 to the specific network device, that is, the network device 300, To the post-change network device 300 for setting a subscription identifier (e.g., 1) indicating that the caller information is to be displayed in a specific field in the origination request of the terminal 1.

Here, the specific field is a specific field, that is, when the specific relay apparatus, that is, the relay apparatus 10 is an apparatus associated with a specific network apparatus, that is, the network apparatus 300 for displaying caller information, (For example, 1) or an unused identifier (for example, 0) for determining whether the terminal 1 is a subscriber terminal for displaying caller information.

That is, the specific field may be the LTR bit in the UUI information included in the ISUP_IAM if the origination request conforms to the ISUP_IAM standard, as described above.

If the terminal 1 is the caller information display target as a result of the confirmation by the display object confirmation unit 120, the call request processing unit 130 displays the caller information in the specific field in the origination request of the terminal 1, for example, the LTR bit in the UUI information To the network device 300 after the change to set the subscription identifier (e.g., 1).

On the other hand, when the display object confirmation unit 120 determines that the terminal 1 is not the caller information display target, the call request processing unit 130 may transmit the call request of the terminal 1 to the specific network device 300 without modification.

Here, the origination request of the terminal 1 received from the terminal 1 through the relay apparatus 10 may be largely different depending on three scenarios.

The first scenario assumes that the relay device 10 is a device associated with the network device 300 for displaying caller information, that is, a wired communication carrier operating the relay device 10 and a mobile communication device The relay apparatus 10 determines that the terminal 1 is the subscriber terminal for displaying caller information.

In this case, the relay apparatus 10 may set a subscription identifier (for example, 1) in a specific field in the origination request of the terminal 1 received through the relay apparatus 10. [

Of course, in this case, since the user of the terminal 1 has already subscribed to the caller information display service through the wired communication company to which the terminal 1 is subscribed, there is no need to register the caller information to the mobile communication company, The information of the terminal 1 is not registered in the DB.

Therefore, in the first scenario, the call interchanging apparatus 100 confirms that the terminal 1 is not the caller information display target based on the telephone number of the terminal 1, and transmits the call request of the terminal 1 to the network device 300 without changing will be.

Meanwhile, in the second scenario, when the relay apparatus 10 is an apparatus associated with the network apparatus 300 for displaying caller information, in other words, operates the wired communication company and the network apparatus 300 operating the relay apparatus 10 A scenario in which the relay apparatus 10 determines that the terminal 1 is not a subscriber terminal for displaying caller information in a case where it is pre-associated with mobile communication companies.

In this case, the relay apparatus 10 may set an unused identifier (for example, 0) in a specific field in the originating request of the terminal 1 received through the relay apparatus 10. [

However, when the user of the terminal 1 desires to use the caller information display service, the terminal 1 registers the caller information to the mobile communication company, not the wired communication company to which the user belongs, so that the information of the terminal 1 is registered .

Therefore, in the case of the second scenario, if it is assumed that the information of the terminal 1 is already registered in the sender information display object DB, the call exchange apparatus 100 judges that the terminal 1 is the caller information display object based on the telephone number of the terminal 1 Change network device 300 that sets a subscription identifier (e.g., 1) in a specific field in the origination request of the terminal 1, e.g., an LTR bit in the UUI information.

The third scenario is to operate the wired communication company and the network device 300 operating the relay device 10 when the relay device 10 is not a device associated with the network device 300 for displaying caller information Which are not affiliated with each other.

In this case, the relay apparatus 10 may set an unused identifier (for example, 0) or a blank in a specific field in the origination request of the terminal 1 received through the relay apparatus 10. [

However, when the user of the terminal 1 desires to use the caller information display service, the information of the terminal 1 may be registered in the sender information display object DB by registering for display of caller information in the mobile communication company.

Therefore, in the case of the third scenario, if it is assumed that the information of the terminal 1 is already registered in the sender information display object DB, the call exchange apparatus 100 determines that the terminal 1 is the caller information display object based on the telephone number of the terminal 1 Change network device 300 that sets a subscription identifier (e.g., 1) in a specific field in the origination request of the terminal 1, e.g., an LTR bit in the UUI information.

In addition, the call switching apparatus 100 transmits the origination request of the terminal 1 received through the relay apparatus 10 to the network apparatus 300 without changing or after changing as described above, That is, requesting confirmation of the destination call exchange apparatus, the destination terminal 200 confirms the destination call exchange apparatus 200 connected to the destination terminal, that is, the terminal 2, from the network apparatus 300. Then, the call switching apparatus 100 performs an existing general call connection procedure for connecting a call between the terminal 1 and the terminal 2 in cooperation with the checked incoming call switching apparatus 200.

When a subscription identifier (for example, 1) is set in a specific field in a call request of the terminal 1 while the call connection procedure between the terminal 1 and the terminal 2 is performed as described above, (For example, the OO bank sales department) from the TIIS 400 and provides it to the called terminal, that is, the terminal 2 via the called party call exchange apparatus 200, so that the caller information of the terminal 1 (For example, the OO Bank Sales Department).

At this time, the caller information (e.g., a phrase, an image, etc.) corresponding to the registered terminal registered for displaying the caller information is stored in the TIIS 400 in cooperation with the Legacy server (not shown) When the TIIS 400 requests the acquisition of caller information of the terminal 1 from the network device 300 as described above, the TIIS 400 transmits the calling number included in the calling request of the terminal 1, the subscription identifier of the specific field in the calling request (e.g., (For example, the OO bank sales department) corresponding to the terminal 1 to the network device 300 after authentication using the business ID and the like.

Of course, in the present invention, too, the call switching apparatus 100 transmits the transmission request of the terminal 1 received through the relay apparatus 10 to the network apparatus 300 as described above, (E.g., 0) can be set in the LTR bit in the P_SFI when the call is originated to the called terminal or is already in communication with another terminal in the process of requesting the call exchange apparatus confirmation, (E.g., 1) can be set in the LTR bit in the P_SFI when the call is not originated to the called terminal or the calling terminal is in communication with another terminal.

Accordingly, in the present invention, the network device 300 determines that a subscription identifier (e.g., 1) is set in a specific field in the origination request of the terminal 1 while the call connection procedure between the terminal 1 and the terminal 2 is performed as described above (For example, the OO bank sales department) of the terminal 1 is acquired from the TIIS 400 when the addition field (i.e., 1) is set in the LTR bit in the P_SFI, To the called terminal, that is, the terminal 2, so that the terminal 2 can display the caller information of the terminal 1 (for example, the OO bank sales department) while the telephone is ringing.

On the other hand, even if a subscription identifier (for example, 1) is set in a specific field in a call request of the terminal 1 while the call connection procedure between the terminal 1 and the terminal 2 is performed as described above, If the subscription identifier (e.g., 1) is not set in the LTR bit in the P_SFI, the caller information display service for the terminal 1 may not be provided.

As described above, the call switching apparatus 100 according to the present invention checks whether or not the calling terminal is the caller information display target based on the calling number when the calling request of the calling terminal is received, (For example, 1) is set in the origination request of the originating terminal and is transmitted to the network device 300 as set by the relay device of the communication company affiliated with the communication company, So that caller information can be displayed on the called terminal according to the subscription identifier (e.g., 1) of the originating request.

As a result, according to the call switching apparatus 100 of the present invention as described above, it is possible to provide a caller information display service for a call attempted at a terminal of a communication company that is not affiliated with a mobile communication company while minimizing the existing network change The effect is obtained.

Hereinafter, an operation method of the call switching apparatus according to a preferred embodiment of the present invention will be described with reference to FIG. For convenience of explanation, the call exchange apparatus 100 on the calling side of the call switching apparatuses 100 and 200 shown in FIG. 1 will be described.

The operation method of the call switching apparatus 100 according to the present invention receives a call request of the calling terminal (S110).

For example, if the terminal 1 is a calling terminal and the terminal 2 is a called terminal as described above, if the terminal 1 attempts to make a call to the terminal 2, i.e., to make a call, To the call exchange apparatus 100 of the mobile communication company to which the terminal 2 is subscribed via the relay apparatus 10 of the communication company (e.g., wire communication company).

The operation method of the call switching apparatus 100 according to the present invention is a method of operating the call switching apparatus 100 in which a calling request of the terminal 1 transmitted from the calling terminal, that is, the terminal 1 through the relay apparatus 10 of the wired communication company to which the specific relay apparatus, .

The operation method of the call switching system 100 according to the present invention checks whether the calling terminal, i.e., the terminal 1 is the caller information display target, based on the calling number confirmed in the received calling request (S120).

For example, the operation method of the call switching apparatus 100 according to the present invention is such that, when the calling number is registered in the caller information display object DB based on the sender information display object DB, the calling terminal, .

At this time, the sender information display target DB is different from the aforementioned subscriber DB based on the relay apparatus 10 of the wired communication company to which the specific relay apparatus, for example, the terminal 1 is subscribed.

In other words, in order to realize the present invention, the sender information display target DB is configured such that, even in the mobile communication company, a terminal registered in a communication company other than the mobile communication company, And stores and manages the information of the registered terminal.

The method of operation of the call switching system 100 according to the present invention checks the origination number in the received origination request when the originating terminal, i.e., the originating request of the terminal 1 is received through step S110, (S120 Yes). If the telephone number of the terminal 1 is not registered in the sender information display object DB, the terminal 1 confirms that the caller information is to be displayed on the caller information display target DB It can be confirmed that the information is not displayed (S120 No).

The operation method of the call switching apparatus 100 according to the present invention is such that if the calling terminal, i.e., the terminal 1 is not the caller information display target (S120 No), the calling request of the terminal 1 is transmitted to the network device 300, that is, the HLR (S140).

Meanwhile, when the terminal 1 is the caller information display target (S120 Yes), a method of operating the call exchange apparatus 100 according to the present invention is to add a subscriber identifier (for example, 1 (S130) to the network device 300 (S140).

Here, the specific field is a specific field, that is, when the specific relay apparatus, that is, the relay apparatus 10 is an apparatus associated with a specific network apparatus, that is, the network apparatus 300 for displaying caller information, (For example, 1) or an unused identifier (for example, 0) for determining whether the terminal 1 is a subscriber terminal for displaying caller information.
