Abstract

PURPOSE: A CNIP(Calling Number Identification Presentation) service method using a destination screen is provided to display a destination screen based on a calling number so that a called subscriber can identify a caller. CONSTITUTION: An HLR(Home Location Register) sets up CNIP service for a subscriber(201). If a caller attempts call origination to the subscriber(202), a calling MSC(Mobile Switching Center) transmits a location request message(LOCREQ) to the HLR to request the present location of the called subscriber(203). The HLR transmits a routing request message(ROUTREQ) to the VLR(Visitor Location Register) of a called MSC to request connection information(204). The called MSC returns a TLDN to the HLR through a routing response message(routreq)(205). The HLR returns the TLDN to the calling MSC through a location response message(locreq)(206). The calling MSC attempts call connection to the called MSC(207). The called MSC informs the called subscriber's terminal that a call is being destined(Alert). Also the called MSC transmits CNIP information to the called terminal(208). The called terminal searches a calling number table for the received calling number(209) and confirms whether an item corresponding to the calling number exists(210). In case that the item corresponding to the calling number exists, the called terminal fetches a destination screen from the memory(211) and displays the fetched screen(212).

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a communication network to which the present invention is applied. Hereinafter, the mobile communication network will be described as an example. However, the present invention will be described in advance that the present invention can be applied to not only a wireless communication network but also a wired communication network (image telephone, etc.).

As shown in FIG. 1, in the caller identification service according to the present invention, a mobile communication network 12, an IWF (InterWorking Function) 14, etc., which is a data transmission device, is required for data transmission between terminals (mobile stations) 11, and WAP. In order to provide a service using (Wireless Application Protocol: a data standard for a wireless Internet service and a transmission protocol), a WAP gateway 15 is further required. Here, the data transmission device refers to a device capable of transmitting data to the terminal from the mobile communication network 12, such as SMS MC, IWF.

The caller identification service server 16 is a server for providing information that may be used as an incoming call screen such as an image, a character, or a video. The caller identification service server 16 uploads an image, a character, a video, or the like provided by a content provider (CP). UPLOAD) Performs a function to convert and provide an image, character, or video.

The mobile communication network 12 is composed of a general mobile communication switch (MSC), a base station, and the like, and the home location register (HLR) 13 is a server having subscriber information and service information. These techniques are already known and will not be described in detail here.

Next, briefly look at the gist of the present invention through Fig. 1, Fig. 1 shows the incoming screen of the called terminal differently according to the caller of the call, and also allows such a function to be set or remotely set by others Shows an example of a terminal, a system and a network environment. Accordingly, user A can designate which display screen to display when a caller is called, and display a display screen to another user B's terminal when another user B receives his (user A) 's call. The output can also be specified with the permission of the other user B.

In the present invention, for the caller identification service, a caller ID and a display screen are set, a caller ID identification process in a network and a terminal, a caller ID remote caller, and the like. Looking at each process in more detail as follows.

First, the mobile communication network of the existing IS-41 system protocol (internet interworking protocol of mobile wireless electrical system) does not transmit the caller's telephone number when an incoming call is announced. Accordingly, the caller identification service of the present invention uses a Calling Number Identification Presentation (CNIP) service, which is a service of IS-41C (the EIA / TIA IS-41C standard in the inter-interworking protocol of mobile wireless electrical systems). This allows the calling number to be sent.

In the present invention, when a call is received, the display screen specified in the corresponding phone number is searched and displayed on the called party's terminal using the calling party's telephone number transmitted as described above, so that the called party can identify the calling party.

In the present invention, the user sets the incoming screen of his service using the image of his terminal, sets the incoming screen of his service using the image of the server, or uses the image of his terminal The caller identification service is provided in various ways, such as setting an incoming call screen of another person's service or setting up an incoming call screen of another person's service using an image of a server.

2 is a flowchart illustrating an exemplary caller identification service method using a called screen according to the present invention. When a call is received, a caller identification service method enables the called party to identify the caller by displaying the called screen differently according to the calling number. The call processing procedure for.

First, in order to be able to use the caller identification service of the present invention, the subscriber is assigned a Calling Number Identification Presentation (CNIP) service (201). At this time, the setting information is stored in the home location register (HLR), this caller phone number display service allows the phone number of the calling terminal to be delivered to the called terminal.

Then, when the caller attempts to make a call (202), the originating mobile communication switch (MSC) sends a location request message (LOCREQ) to the home location register (HLR) to request the current location of the subscriber (203).

Then, the home location register (HLR) requests the connection information by sending a route setting request message (ROUTREQ) to the visitor location register (VLR) of the destination mobile communication switch (MSC) where the called party is located (204).

The terminating mobile communication exchange then returns the temporary connection number (TLDN) to the home location register (HLR) via a routing response message (routreq) (205), whereby the home location register locates the temporary connection number (TLDN). Return to originating mobile switching center (MSC) via response message (locreq) (206).

Then, the calling mobile communication exchange attempts to connect the call to the called mobile communication switch (207), and the called mobile communication exchange notifies the called terminal of the incoming call (Alert). In addition, since the subscriber is subscribed to the CNIP service, the terminating mobile communication exchange transmits the CNIP information to the called terminal (208). At this time, the called terminal basically outputs the calling number of the calling telephone number indication (CNIP) information on the screen of the called terminal, but there is currently a legal problem so that the calling number is not output on the screen.

Thereafter, the called terminal searches for the received caller ID in the caller ID table prepared in advance (209) and checks whether an item corresponding to the caller ID exists (210). As a result, if the calling number exists, the incoming call screen corresponding to the calling number is read from the memory (211), and if the calling number does not exist, the base screen is read from the memory (212).

Thereafter, the called terminal displays the read incoming call screen on the display of the terminal (213). In this case, the video is displayed as a video.

The terminal continues to process the call (214) and the call is connected when the called party answers (215). The following procedure is the same as the general call processing procedure.

As described above, in the present invention, by using an outgoing telephone number display (CNIP) service, the caller identification service can be provided without modification of the existing network. In addition, the terminal stores the 'calling number table' in the memory to store the calling number and the corresponding incoming screen, which stores the corresponding 'calling number' and the corresponding called screen address as a table, It provides a function to find out the memory address of the corresponding incoming screen.

Meanwhile, in the present invention, the above-mentioned 'calling number table' is preset in various ways, but this setting process may be executed in the caller identification service server through the WAP service, but the present invention will be described by way of example. Let's do it. Examples thereof will be described in detail with reference to FIGS. 3 to 6 as follows.

3 is a flowchart of a first embodiment of a process of setting a call screen according to the present invention, which shows an example of setting a call screen of a service by using a picture, a character, an image, a video, or the like in a terminal thereof; have. That is, it shows the process of setting which incoming call screen is displayed on the terminal when the caller receives a call from which caller.

Through this process, the user can register a new incoming screen for a new calling number or modify or delete the incoming screen for an existing calling number. Therefore, when a new call is received, the corresponding incoming call screen is displayed if the caller ID is set by the subscriber.

Looking at the above process in detail with reference to Figure 3, first, the subscriber selects the caller identification service to enter the caller ID you want to specify (301) the terminal to the incoming call screen to be used for the inputted caller ID number, picture, character, image Or select from the video (302).

Thereafter, the terminal searches the calling party number table with the inputted calling number (303) and checks whether an item corresponding to the inputted calling number exists (304).

As a result of the check, if the caller number exists, the incoming call screen of the caller ID is changed to the newly selected caller's call screen (305). If the caller ID does not exist, a new item is added to the caller ID table. The memory address is newly registered in the calling party number table (306).

As such, for the caller identification service of the present invention, the processing procedure of the terminal is changed as shown in FIG. Meanwhile, in the above example, the incoming call screen selection process 302 may be performed after the calling number search process 303 or the confirmation process 304. As such, the detailed process can be changed in various ways.

FIG. 4 is a flowchart of a second embodiment of a process of setting up an incoming call screen according to the present invention, and shows an example of setting up an incoming call screen of one's own service using a picture, a character, an image, or a video of a caller identification service server; have.

As shown in FIG. 4, in the present invention, a user accesses a caller identification service server through a terminal, selects and downloads a picture, a character, an image, or a video provided by the server, and sets an incoming call screen of his terminal. do.

In this way, the user can download his or her desired image among various images, characters or videos in the caller identification service server and use it as an incoming call screen. The user can also download and set the caller ID entered from the caller identification service server in the terminal. To this end, the caller identification service server has various images, characters or videos, and when a user selects an incoming call screen with a calling number to be applied, the caller identification service server transmits it to the user's terminal. It also converts photos into suitable images, saves them, and downloads them when the user selects them.

Referring to this process in detail with reference to Figure 4, first, when the subscriber accesses the caller identification service server using the terminal (401), the caller identification service server selects a desired image, character or video from the image classification list that it has After the 402, the caller receives a calling number to be applied when the selected image is used as the incoming screen (403). In other words, the selected image is used as the incoming call screen when a call of the calling number is received.

Then, when the subscriber confirms, the caller identification service server transmits the selected image data and the calling number to the subscriber's terminal (404). Then, the information is transmitted to the terminal through a data transmission device such as IWF and WAP gateway (405). In this case, when the WAP is implemented, the terminal receives the corresponding information from the caller identification service server through a WML script.

After receiving the image data and the calling number, the terminal performs a script (SCRIPT) for calling party identification service (406) to perform the following process.

That is, the received caller ID is searched from the caller ID table (407) to check whether there is an item corresponding to the received caller ID (408). If present, the image is stored in memory and the incoming call screen address used for the caller ID is received. The image is changed to the address of the received image (409). If it does not exist, the image is stored in the memory, a new item is added to the calling number table, and the received calling number and image address are registered (410).

Then, execution of the script SCRIPT is completed (411).

As such, for the caller identification service of the present invention, the processing procedure of the terminal is changed as shown in FIG. On the other hand, in the above example, the caller ID input process 403 may be performed after the image transmission process 404 is performed, so that the caller identification service server may be input to the terminal without inputting the caller ID. As such, the detailed process can be changed in various ways.

5 is a flowchart of a third embodiment of a process of setting up an incoming call screen according to the present invention, and shows an example of setting up an incoming call service screen of another person using a picture, a character, an image, a video, etc. in his terminal. have.

As shown in the figure, the third embodiment shows a process of setting the incoming call screen designated by the third party to be displayed when the call is made by another person. To this end, the telephone number of the calling terminal is designated as a calling number for displaying the incoming call screen on the called terminal. Therefore, when a call comes in from a telephone number of a calling terminal later, the called terminal already displays the incoming screen transmitted from the calling terminal at the called terminal.

Referring to FIG. 5, when the service is started as the subscriber selects a transmission function of the caller identification service in his terminal (501), the calling terminal receives the telephone number of the receiving terminal from the subscriber (502).

Subsequently, the calling terminal selects the incoming call screen to be transmitted to the subscriber. When the subscriber selects the incoming call screen (503), the subscriber confirms the transmission. When the subscriber confirms the transmission (504), the selected terminal reads the selected image from the memory. The called party number is transmitted together (505). Then, the information is transmitted to the receiving terminal through a data transmission apparatus such as an IWF and a WAP gateway (506).

Then, the receiving terminal receiving the image data and the incoming information performs a script (SCRIPT) for the caller identification service (507) to perform the subsequent processes.

That is, the receiving terminal uses the caller ID of the received message as the caller ID of the image (508) to display that the message of the caller identification service is received on the screen, and displays the caller's phone number and the image on the screen, and then the message A request is made for consent to use the contents of the data (509, 510).

Thereafter, if the user does not agree, the script execution is completed (515), and if the user agrees, the service is continued.

That is, the received caller ID is searched from the caller ID table (511) to check whether there is an item corresponding to the received caller ID (512). If present, the image is stored in the memory and the incoming call screen address used for the caller ID is received. The image is changed to the address of the received image (513). If it does not exist, the image is stored in the memory, a new item is added to the calling number table, and the received calling number and image address are registered (514).

Then, execution of the script SCRIPT is completed (515).

As such, for the caller identification service of the present invention, the processing procedure of the terminal is changed as shown in FIG.

6 is a flowchart of a fourth embodiment of a process of setting a call reception screen according to the present invention, which shows an example of setting a call reception screen of a service of another person using a picture, a character, an image or a video of a server.

As shown in the figure, in the fourth embodiment, the caller identification service server transmits the calling party's calling party number, which is designated as the calling party number for the incoming call screen at the receiving terminal. Therefore, when a call comes from a subscriber who transmits the calling number later, the receiving terminal displays the received image so that the called party can distinguish the calling party. On the other hand, a user using such a caller identification service can be used even if the user is not a subscriber.

Referring to FIG. 6, in detail, a user first accesses a caller identification service server using a calling terminal (601), and selects a desired image, character or video from an image classification list in the caller identification service server, or uploads himself / herself (UPLOAD). In operation 602, the converted image is selected. Then, the user inputs the incoming call number of the receiving terminal to receive the selected image (603). At this time, it is necessary to check whether the subscriber of the input telephone number is a subscriber to the caller identification service.

Then, if the user confirms the transmission, and transmits the image data and the user's calling number to the terminal of the incoming call number (604). Then, the information is transmitted to the receiving terminal through a data transmission device such as IWF and WAP gateway (605).

Then, the receiving terminal receiving the image data and the incoming information performs a script (SCRIPT) for the caller identification service (606) to perform the subsequent processes.

That is, the receiving terminal uses the caller ID of the received message as the caller ID of the image (607) to display that the message of the caller identification service is received on the screen, and displays the caller's phone number and the image on the screen, and then the message. A request is made for consent to use the content of the code (608,609).

Thereafter, if the user does not agree, the script execution is completed (614), and if the user agrees, the service is continued.

That is, the received caller ID is searched from the caller ID table (610) to check whether there is an item corresponding to the received caller ID (611). If present, the image is stored in the memory and the incoming call screen address used for the caller ID is received. The image is changed to the address of the received image (612). If it does not exist, the image is stored in the memory, a new item is added to the calling number table, and the received calling number and image address are registered (613).

Then, execution of the script SCRIPT is completed (614).

As such, for the caller identification service of the present invention, the processing procedure of the terminal is changed as shown in FIG.
