1 is a block diagram illustrating a system for providing a caller setting information display service according to an embodiment of the present invention.

As illustrated in FIG. 1, a mobile communication system including a caller setting information display service providing system may include a roaming network, an international circuit, a home network, a calling terminal 1010, and a called terminal 1020. The caller setting information display service providing system according to an embodiment of the present invention is included in the home network shown in FIG.

Roaming network (Roaming Network) refers to a mobile communication network or a mobile communication system in which a roaming mobile communication terminal performs wireless communication. For example, when a user of a terminal that is subscribed to a Korean mobile communication company wants to use a communication service such as an incoming / outgoing call in Korea, the user subscribes to a roaming service. In this case, a US communication network used when a terminal subscribed to a roaming service performs wireless communication in the US is called a roaming network.

The home network is a communication network originally used by a terminal subscribed to a roaming service. In the case of the above-described example, the terminal is a terminal that is originally subscribed to a mobile communication company in Korea, and before using the roaming service, the communication is performed using a Korean communication network, thus the home network becomes a Korean communication network.

An international circuit network is a communication network that connects different roaming networks with different home networks, and a terminal included in a roaming network can make a call with a terminal included in a home network through an international circuit network.

Hereinafter, in this specification, the roaming network, the home network, and the international circuit network are used as the above meanings. In an embodiment, the calling terminal 1010 located in the roaming network attempts to connect to the called terminal 1020 located in the home network. It will be described on the premise that the present invention.

The caller setting information display service means that when a caller makes a call to a caller terminal, the caller rings and the caller's phone number is set in advance along with the caller's phone number display-for example, 'Hello KTF It is nothing. ' -Refers to the service indicated by the called terminal. Hereinafter, it will be clear that the caller setting information display service is used in the same meaning as above.

In the conventional caller setting information display service, when the calling terminal 1010 belongs to the roaming network and makes a call to the called terminal 1020 included in the home network, the number of the calling terminal is distorted and the calling party setting information is called. There was a problem that is not displayed.

 The reason why the number of the calling terminal is distorted and displayed on the called terminal is that the conventional calling terminal 1010 belongs to the roaming network and makes a call to the called terminal 1020 of the home network. This is because a distortion of the called number does not occur, but a distortion of the calling number occurs during the process of passing through 1200 to the gateway mobile switching center 1500 of the home network.

However, according to the present invention, when the international roaming originating terminal 1010 registers its location, it transmits the subscriber profile to the gateway location register of the home network through the ISD, and also transmits the outgoing CAMEL subscription information (O-CSI). The intelligent network call origination message generated by the overseas mobile switching center 1100 is transmitted without distortion to the home network via the international signal network (INTERNATION SCCP CARRIER), and the caller setting information and the calling terminal number are received. The terminal 1020 is displayed without being distorted.

 Hereinafter, the location registration process of the international roaming central calling terminal as described above will be described in more detail with reference to FIG. 3.

Hereinafter, a method of providing a caller setting information display service according to another embodiment of the present invention will be described with reference to FIGS. 3 to 6.

3 is a control flowchart illustrating a location registration process of a calling terminal, which is a premise of a method for providing a caller setting information display service according to another embodiment of the present invention.

First, the calling terminal 1010 located in the roaming network attempts to register a location abroad (S310). When the originating terminal 1010 attempts to register the location, the gateway location register 1800 receives the location registration message via the international roaming service control device 1300 and transmits it to the home location register 1600 again (S320). ).

The gateway location register 1800 receives a subscriber profile transmission message (ISD: Insert Subscriber Data) including the profile of the calling terminal 1010 from the home location register 1600 (S330), and then includes the subscriber profile transmission message in the subscriber profile transmission message. The information on whether to subscribe to the caller setting information display service among the profiles of the called terminal is stored (S340). Then, the information on whether to subscribe to the caller setting information display service is transmitted to the international roaming service control device so that the international roaming service control device can know what service the subscriber uses.

The gateway location register 1800 determines whether the roaming network in which the calling terminal 1010 is located is a network in which the CAMEL communication standard is supported (S350).

CAMEL communication standard stands for Customized Applications for Mobile network Enhanced Logic. If the roaming network is supported by the CAMEL communication standard, call processing initiated by the originating terminal in the roaming network can be simple and efficient compared to the conventional call processing process. In a conventional roaming network, when a calling terminal attempts to make a call connection with a destination terminal of a home network, a call is inevitably routed from a home network to a roaming network and back to a roaming network. However, when a calling terminal attempts to make a call from a roaming network supported by the CAMEL communication standard to a called terminal in the home network, the call is routed directly from the roaming network to the home network, which is much simpler and more efficient than the conventional call processing process. have.

The present invention assumes that roaming networks support the CAMEL communication standard. Therefore, according to an embodiment of the present invention, when the calling terminal 1010 in the roaming network attempts to make a call connection to the called terminal in the home network, an intelligent network call origination message message is directly transmitted from the roaming network to the home network.

If the roaming network is a network supported by the CAMEL communication standard, the gateway location register 1800 includes the outgoing CAMEL subscription information in the subscriber profile transmission message and transmits it to the foreign mobile switching center 1100 (S360). At this time, the outgoing CAMEL subscription information is set to trigger a call to the international roaming service control device 1300. As such, since the outgoing CAMEL subscription information is registered in the foreign mobile switching center 1100, the intelligent network call origination message may always be transmitted to the international roaming service control device 1300 when the originating terminal 1010 originates a call. .

As described above, the location registration process of the calling terminal 1010 indicates a process of registering the location of the calling terminal 1010 in the roaming network, and all embodiments of the method for providing caller setting information display service according to the present invention will be described later. It is a premise for

As shown in FIG. 3, according to the present embodiment, since outgoing CAMEL subscription information is registered at the foreign exchange 1100 through the location registration process of the calling terminal, when the calling terminal 1010 sends a call, the gateway moves. The international roaming control device 1300 directly receives the intelligent network call origination message through the international circuit network without passing through the switching center 1500. Through this process, as the call setting information message is received by the gateway location switching center 1500 through the international circuit operator 1200, the caller setting information may not be displayed on the called terminal.

Hereinafter, a method of providing caller setting information display service of an international roaming service control device according to another embodiment of the present invention will be described in detail with reference to FIGS. 4A to 6C. 4A to 6C are flowcharts illustrating a method for providing caller setting information display service of an international roaming service control device according to another exemplary embodiment of the present invention.

 The control flow diagram shown in FIGS. 4A to 6C clarifies that an embodiment of the present invention is shown in which the intelligent network call origination message is an IDP, the connection message is a CONNECT, and the call establishment information message is an initial address message.

First, referring to FIGS. 4A and 4B, a method for providing caller setting information display service based on an integrated services digital network user part (ISUP) of an international roaming service control device according to a fourth embodiment of the present invention. Let's take a look. 4A and 4B, the method for providing caller setting information display service of the international roaming service control apparatus according to the fourth embodiment of the present invention is performed by the international roaming service control apparatus described above with reference to FIG. 2A. Since it is the same as how to do it, duplicate description is omitted and briefly described.

As the call setup is attempted from the calling terminal 1010 (S410), an intelligent network call origination message including the calling terminal number and the called terminal number is received by the international roaming service control device 1300 (S420). As described above, when the originating terminal 1010 originates a call, the international roaming service control device 1300 directly receives the intelligent network call origination message by the originating CAMEL subscription information stored in the overseas mobile switching center 1100. (S420). That is, when a call setup is attempted from the originating terminal 1010 by the originating CAMEL subscription information transmitted from the gateway location register 1800 of the mobile communication system to the overseas mobile switching center 1100, international roaming is performed at the overseas mobile switching center 1100. The intelligent network call origination message is directly received by the service control device 1030.

Next, the international roaming service control device 1300 generates a temporary mobile station roaming number, maps and stores the generated temporary mobile station roaming number and the calling terminal number and the called terminal number included in the intelligent network call originating message (S430). . The special message and the temporary mobile station roaming number are included in the connection message and transmitted to the overseas mobile switching center 1100 (S431).

The first call setting information message including the special identification number and the temporary mobile station roaming number is received from the foreign mobile switching center 1100 that receives the connection message via the international circuit operator 1200 (S432).

Then, the caller setting information display service is provided using the caller terminal number and the caller terminal number, which will be described in more detail as follows.

The international roaming service control apparatus 1300 extracts the calling terminal number and the called terminal number from the received intelligent network call origination message using the temporary mobile station roaming number (S440).

Through the extracted calling terminal number, the international roaming service control apparatus 1300 determines whether the calling terminal 1010 subscribes to the caller setting information display service (S450).

When the international roaming service control device 1300 determines that the calling terminal 1010 is subscribed to the caller setting information display service, the international roaming service control device 1300 sets the caller to the caller setting information display service providing server 1400. The information display service request message is transmitted (S460). At this time, the caller setting information display service request message includes a calling terminal number and a called terminal number.

As such, when the caller setting information display service request message is transmitted to the caller setting information display service providing server 1400, caller setting information corresponding to the calling terminal number is received in response to the caller setting information display service request message (S470). ).

That is, a response message to the caller setting information display service request message including the caller setting information is received (S470). For example, when a user of the calling terminal 1010 has set the message 'Hello, KTF,' as the caller setting information, the caller setting information display service providing server 1400 is included in the caller setting information display service request message. According to the called terminal number, the user of the calling terminal transmits the message 'Hello KTF Anyone' message to the international roaming service control device 1300. Since the set messages are different according to the calling terminal number, the international roaming service control apparatus 1300 receives caller setting information corresponding to the calling terminal number (S470).

As such, when the international roaming service control apparatus 1300 receives the caller setting information, the international roaming service control apparatus 1400 receives the calling terminal number and the called terminal number obtained in step 440 and the caller setting information obtained in step 470. A second call setup information message is generated and transmitted to the gateway mobile switching center 1500 (S480). In this case, the second call setup information message corresponds to an embodiment of the message call setup request message.

Then, the gateway mobile switching center 1500 receiving the call setup information message proceeds with the general incoming process. The gateway mobile switching center 1500 transmits a third call setting information message including the calling terminal number, the calling party setting information, and the mobile station roaming number to the called mobile switching center 1700 (S490).

Then, the destination mobile switching center 1700 transmits the calling terminal number and the calling party setting information to the called terminal 1020 using the information included in the third call setting information message (S491), and accordingly the called terminal 1020. Caller terminal number and caller setting information is displayed.

That is, according to the fourth embodiment of the present invention, since the international roaming control device receives the call setting information message received from the foreign mobile switching center 1100 as it is (S432), the originating terminal 1010 in the overseas roaming network Even when making a call to the called terminal 1020 located in the domestic home network, caller setting information may be displayed. In this way, the caller setting information is displayed in the same manner as when making a call in Korea, even when roaming, so that the called terminal 1020 cannot know that the calling terminal 1010 is roaming.

Next, referring to FIGS. 5A to 6C, a method of providing a caller setting information display service of a CAMEL-based international roaming service control device according to an embodiment of the present invention will be described.

First, referring to FIGS. 5A to 5C, a method of providing a CAMEL-based caller setting information display service of an international roaming service control device according to a fifth embodiment of the present invention will be described.

(S535). In this case, the calling terminal number included in the second intelligent network call originating message is distorted because it is transmitted through the international circuit operator 1200, and the special identification number and the temporary mobile station roaming number are included corresponding to the called terminal number.

As such, the method for providing caller setup information display service according to the present embodiment receives and processes an ISUP-based call setup information message by receiving and processing a second intelligent network call origination message instead of an ISUP-based call setup information message. In comparison with the fourth embodiment to be processed, the load is reduced.

The international roaming service control apparatus 1300 extracts the calling terminal number and the called terminal number from the first intelligent network call origination message by using the temporary mobile station roaming number (S540). Through the extracted calling terminal number, the international roaming service control apparatus 1300 determines whether the calling terminal 1010 subscribes to the caller setting information display service (S550).

If it is determined that the calling terminal 1010 is subscribed to the caller setting information display service, the international roaming service control device 1300 transmits the caller setting information display service request message to the caller setting information display service providing server 1400 (S560). ). At this time, the caller setting information display service request message includes a calling terminal number and a called terminal number.

As such, when the caller setting information display service request message is transmitted to the caller setting information display service providing server 1300, caller setting information corresponding to the calling terminal number is received in response to the caller setting information display service request message (S570). ). For example, when the user of the calling terminal 1010 has set the message 'Hello KTF,' as the caller setting information, the caller setting information display service providing server 1400 is included in the caller setting information display service request message. According to the calling terminal number, the user of the calling terminal transmits the message "Hello KTF is a certain number" to the international roaming service control device 1300.

As such, when the international roaming service control device 1300 receives the caller setting information (S570), the international roaming service control device 1300 obtains the calling terminal number and the called terminal number obtained in step 540 and the step 570. A second connection message including caller setting information is generated and transmitted to the gateway mobile switching center 1500 (S580). In this case, the second connection message corresponds to an embodiment of the message call setup request message.

In addition, the gateway mobile switching center 1500 having received the second connection message transmits a call setup information message including the calling terminal number and caller setting information to the called mobile switching center 1700 to proceed with the call. . Then, the destination mobile switching center 1700 transmits the calling terminal number and the calling party setting information to the called terminal 1020 by using the information included in the call setting information message (S592), and sends the calling terminal number to the called terminal 1020. And caller setting information is displayed. Through the above-described process, even when the calling terminal 1010 makes a call to the called terminal 1020 located in the domestic home network from the overseas roaming network, the calling terminal number and caller setting information may be displayed together. .

Finally, referring to FIGS. 6A to 6C, a method of providing a CAMEL-based caller setting information display service of an international roaming service control device according to a sixth embodiment of the present invention will be described.
