Description

METHOD FOR PROVIDING CHANGE OF CALLING NUMBER IN CALLING IDENTIFICATION DISPLAY SERVICE AND HOME LOCATION REGISTER THEREFORE}

The present invention relates to a caller information display service, and more particularly, to a caller ID change display service providing method and a system for displaying a caller's information before a change of a caller who changed a phone number as caller information. .

Calling Identification Display (CID) service refers to a service that displays a caller's name or telephone number on a terminal of a called subscriber before initiation of a call. Using the caller information display service, communication subscribers can know the caller's name or phone number before answering the call so that they can check who is calling. This caller information display service allows communication subscribers to not receive unwanted calls, or to identify from whom the missed call comes from.

On the other hand, when the subscribers subscribe to the communication service is assigned a unique phone number to use. However, if a terminal is lost or malfunctions, a new terminal may be purchased and an existing telephone number may be used as it is, but a new telephone number may be assigned and used by changing the telephone number. In recent years, service numbers (eg, 011, 016, 019) for distinguishing carriers have been consolidated into one service number (eg, 010). In particular, in order to use the 3G service while using the existing 2G service, the service number allocated from the existing 2G service should be changed to the service number for the 3G service. Therefore, a problem arises that the telephone number must be changed.

If you change the phone number in this way, there is a troublesome problem of notifying the neighbors, colleagues, etc. a new phone number one by one, in particular, workers hesitate to change the phone number due to the social relationship formed by the existing phone number, The policy of consolidating phone numbers to 010 identification numbers, which is being promoted by the United States, is being significantly delayed. To solve this problem, the telecommunications provider is providing a service that automatically connects to a new phone number when a call is made to the phone number before the change. In this process, the phone number change notification service is provided to the caller by voice notification that the caller's phone number has been changed or by text message.

However, such a conventional telephone number change notification service is limited to a service of notifying a caller who changes a telephone number to a caller who changes the telephone number. In contrast, when a subscriber who changes a telephone number makes a call, There is no way to notify the caller of his or her phone number change. Therefore, the terminal of the other party is not the existing phone number, but the newly changed phone number is displayed as the caller information, the other party has a problem that refuses to receive a call because it is mistaken as a caller.

The present invention has been proposed to solve the above problems, the subscriber before changing the phone number in the process of making a call so that the subscriber's phone number before the change is changed to display the caller information on the other terminal, An object of the present invention is to provide a calling number change indication service providing method and a system therefor.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention for achieving the above object, a method for providing a caller ID change indication service in a communication system includes: a receiving step of receiving a caller ID change indication service subscription request from a communication subscriber; An authentication step of authenticating whether the communication subscriber is a subscriber who has changed a telephone number; A registration step of registering a telephone number before and after the change of the communication subscriber upon successful authentication; A change step of changing the after-change telephone number included in the outgoing call originating from the communication subscriber as the outgoing telephone number to the before-change telephone number; And an incoming step of receiving the outgoing call with the outgoing telephone number changed to the called party.

In addition, the system for providing a caller ID change indication service according to another aspect of the present invention for achieving the above object is to authenticate whether the communication subscriber requesting subscription to the caller ID change indication service is a subscriber whose telephone number has been changed. Authentication means; And registering the telephone number before and after the change of the communication subscriber upon successful authentication in the authentication means, and changing the telephone number after the change included as the outgoing telephone number in the outgoing call when the outgoing call is received from the communication subscriber. It includes; core network to process the incoming.

The present invention as described above, by displaying the phone number before the change of the caller who changed the phone number on the called party's terminal as the caller information, the caller changes the phone number after the caller does not notify the acquaintances to the acquaintances, This allows you to see who the caller is. Accordingly, 2G subscribers, such as 011 and 016, can be subscribed to the 010 number to facilitate the integration of the mobile phone identification number.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which: There will be. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a schematic configuration of a communication system for a call number change indication service according to an embodiment of the present invention.

As shown in FIG. 1, the communication system according to the present embodiment includes mobile terminals 110 and 120, a wireless access network 130, a core network 140, and an authentication server 150.

In FIG. 1, the mobile terminals 110 and 120 are portable mobile communication terminals for providing a voice call and / or a video call during movement. This is possible. Preferably, the mobile terminal (110, 120) stores the address book, search for the corresponding name in the address book using the caller phone number included in the incoming call and displays the phone number and name as caller information. If there is no name corresponding to the address book, only the caller's telephone number is displayed as caller information.

The mobile subscriber who changes the phone number subscribes to the calling number change indication service through the mobile terminals 110 and 120 or by accessing a call center or a dedicated web site of an agency or a telecommunication company. In the case of using the mobile terminals 110 and 120, the subscriber accesses the related wireless web page through the mobile terminals 110 and 120 to subscribe to the calling number change indication service or calls the call center to subscribe to the calling number change indication service. (170). When not using the mobile terminals 110 and 120, the subscriber accesses a dedicated web site operated by an agency or a telecommunication company and subscribes to the calling number change indication service (160).

The mobile terminals 110 and 120 are connected to the core network 140 of the mobile communication system through the wireless access network 130. In FIG. 1, the mobile terminal 110 is described as a calling terminal that changes a phone number and makes a call as a terminal of a subscriber who subscribes to a calling number change indication service, and the mobile terminal 120 originates from the calling terminal. The following describes a call terminal receiving a call.

The radio access network 130 includes a base station Node B and a base station controller (RNC). The base station performs radio signal transmission and reception, radio channel encoding and decoding, baseband signal processing, diversity (space), radio resource management, and self maintenance. The base station controller performs functions such as matching with the base station, inter-cell handover processing, call control, and the like, and one base station controller controls several base stations.

The core network 140 is a core network of a mobile communication system that provides a mobile communication service to the mobile terminals 110 and 120 connected through the wireless access network 130. The core network 140 includes a switch, a home location register, an intelligent network, and a packet switching node. And the like. The core network 140 receives and registers the service subscription information of subscribers who have changed the telephone number and subscribed to the caller ID change indication service according to the present invention from the authentication server 150, and if there is a call origination of the subscribers, the caller The current phone number set as the caller's phone number of the call (that is, the phone number after the change) is changed to the phone number before the change and the call is processed (180). A specific method of the calling number change processing in the core network 140 will be described later.

The authentication server 150 authenticates whether the mobile communication subscribers who want to subscribe to the calling number change indication service can subscribe to the service, and registers the service subscription information in the core network 140 when the authentication is successful. An example of the authentication server 150 is KT's WISE system.

The caller ID change indication service according to the present invention is provided not only to all mobile subscribers but only to subscribers whose telephone numbers are changed. Therefore, when the authentication server 150 receives a request for approval of the caller ID change indication service from a call center or a communication company's dedicated web site, the authentication server 150 checks the phone number change history of the mobile communication subscriber who wants to subscribe and changes the phone number. Only if the service subscription is approved and the subscription information according to the registration in the core network 140.

2 is a flowchart illustrating a method of subscribing to a calling number change indication service according to an embodiment of the present invention.

Referring to FIG. 2, a mobile subscriber who wants to subscribe to a calling number change indication service subscribes to a calling number change indication service through a call center or a wireless web page or a wired web page dedicated to a carrier. Accordingly, the subscriber's calling number change indication service subscription request is transmitted to the authentication server 150 (S201). As the subscription request information, the subscriber's social security number, the current telephone number, and the like are transmitted.

Upon receiving the service subscription request, the authentication server 150 first checks whether the mobile communication subscriber who requested the subscription is a subscriber whose telephone number has been changed (S203). If the mobile communication subscriber is not the subscriber who changed the phone number, the authentication server 150 rejects the caller ID change indication service subscription request and transmits a service subscription impossibility message to the device that received the subscription request (S209). . In this case, the equipment receiving the subscription request is a counselor terminal of a call center or a web server that provides a wired or wireless web page.

On the contrary, when the mobile communication subscriber is a subscriber who has changed the phone number, the authentication server 150 registers service information of the mobile communication subscriber to the core network 140 (S205), and receives the subscription request to the equipment. The service subscription completion guide message is transmitted (S207). The registration of the service information consists of registering a telephone number before and after the change of the mobile communication subscriber with a device that performs the calling number change indication service logic, such as a home location register and an intelligent network device.

Accordingly, subscribers who do not change their phone number cannot use the calling number change indication service according to the present invention, and only subscribers who change the phone number can use the calling number change indication service according to the present invention.

3 is a flowchart illustrating a method for providing a calling number change indication service in a core network according to an embodiment of the present invention.

As shown in FIG. 3, when a call is sent from the calling terminal 110 having changed the telephone number to the called terminal 120, the calling call is transmitted to the calling side exchange of the core network 140 through the wireless access network (S301). ). At this time, the outgoing call includes the calling party number and the called party number.

The originating exchange receiving the originating call verifies the calling party's subscriber profile at the visited location register. However, in the subscriber profile of the caller whose telephone number is changed, trigger information for registering the calling home location register must be registered. Accordingly, the calling exchange exchange transmits a call initiation query message (Initial DP) including the calling party number and the called party number to the calling party home location register according to the trigger information (S303).

The calling party's home location register checks the calling party's subscriber profile based on the call initiation query message to confirm the subscription of the calling number change indication service, and thus includes the intelligent network routing information to route the calling call to the intelligent network. The message is transmitted to the calling exchange (S305, S307).

The originating exchange receiving the connection message routes the outgoing call to the intelligent network according to the routing information included in the connection message (S309), and the intelligent network receiving the call receives the registered information as described with reference to FIG. The caller's telephone number of the outgoing call is changed to the telephone number before the change (S311).

Then, the intelligent network requests the incoming side exchange to process the incoming call using the changed originating telephone number (S313). The receiving side exchange receiving the incoming processing request performs the incoming processing of the outgoing call to the called terminal. As described above, since the calling party telephone number of the outgoing call has been changed from the telephone number after the change to the telephone number before the change, the called terminal 120 In the caller's telephone number, the caller's previous telephone number is displayed (S315 and S317).

As described above, in the present embodiment, the information according to the outgoing number change indication service subscription is registered in the intelligent network, and when the call is sent from the subscriber, the outgoing call is changed to the outgoing number in the intelligent network and is received by the called terminal.

4 is a flowchart illustrating a method of providing a calling number change indication service in a core network according to another embodiment of the present invention.

As shown in FIG. 4, when a call is sent from the calling terminal 110 having changed the telephone number to the called terminal 120, the calling call is transmitted to the calling side exchange of the core network 140 through the wireless access network (S401). ). At this time, the outgoing call includes the calling party number and the called party number.

At this time, registration of the calling number change indication service information described with reference to FIG. 2 is performed at the caller's home location register. And, when registering the location of the calling terminal 110, the home location register of the caller lowers the subscriber profile to the calling exchange. The subscriber profile includes the telephone number before and after the change as the calling number change indication service subscription information.

Thus, the originating exchange receiving the originating call verifies the calling party's subscriber profile at the visited location register. However, since the caller ID change indication service information is registered in the subscriber profile of the caller who changed the phone number as described above, the calling party exchange checks the caller ID change indication service information (S403) and accordingly the caller's call of the caller. Change the number from the telephone number before the change to the telephone number after the change (S405).

Subsequently, the calling side exchange transmits the called location query message to the called party's home location register that receives the called party's information for the incoming call processing (S407), and receives the called location response message from the called party's home location register. It receives (S409).

The originating exchange, which has received the called location response message, transmits an initial address message (IAM) to the called exchange according to the routing information included in the called location response message and requests an incoming call processing (S411). Here, the initial address message includes a telephone number after the change of the sender.

The receiving side exchange receiving the incoming processing request performs the incoming processing of the outgoing call to the receiving terminal 120. As described above, since the calling party's telephone number is changed to the telephone number before the change, the called terminal 120 has the calling party's telephone. As a number, the telephone number before the change is displayed instead of the telephone number after the change (S415).

As described above, in the present embodiment, the information according to the caller ID change indication service subscription is registered in the subscriber's home location register, and when the call is sent from the subscriber, the caller's telephone number of the caller is changed from the calling party exchange to the called terminal. Incoming call is processed.

5 is a flowchart illustrating a method for providing a calling number change indication service according to another embodiment of the present invention.

As shown in FIG. 5, when a call is sent from the calling terminal 110 having changed the telephone number to the called terminal 120, the calling call is transmitted to the calling side exchange through the wireless access network (S501). At this time, the outgoing call includes the calling party number and the called party number.

At this time, registration of the calling number change indication service information described with reference to FIG. 2 is performed at the caller's home location register. When the location of the calling terminal 110 is registered, the home location register of the caller drops the subscriber profile to the calling exchange, and the calling profile of the subscriber includes trigger information that must pass through the calling home location register. Yes, O-CSI = 2000) is registered.

Therefore, the calling side exchange 130 receiving the outgoing call checks the calling party's subscriber profile at the visited location register. As described above, the calling party's subscriber profile whose telephone number has been changed must pass through the calling home location register. Since trigger information (for example, O-CSI = 2000) is registered (S503), the calling exchange exchanges the call initiation query message including the calling party number and the called party number to the calling party home location register according to the trigger information. Initial DP) is transmitted (S505).

The calling party's home location register checks the calling party's subscriber profile based on the call initiation query message to confirm the calling number change indication service subscription, thereby retrieving the calling party's unchanged phone number and including the unchanged phone number. (Connect) transmits a message to the calling exchange (S507).

The originating exchange, which has received the connection message, transmits the called location query message for the incoming call processing of the outgoing call to the called party's home location register accommodating the called party's telephone number (S509). Then, the called party home location register checks the location registration information of the called terminal based on the called party's telephone number and transmits a routing information request message to the called party's exchange (S511).

The called party exchange assigns a routing number and transmits a routing information response message to the called party home location register (S513). The called party home location register receiving the routing information response message transmits the called location response message including the routing number to the calling exchange (S515).

The originating exchange, which has received the called location response message, proceeds with the call establishment procedure based on the routing information, where the originating exchange before changing the originator of the originating message included in the connection message received from the originating home location register in step S507. The call setup procedure is performed using the telephone number (S517).

Specifically, the originating exchange exchanges an initial address message (IAM) for a call connection to the called exchange, wherein the initial address message is transmitted with the telephone number before the change as the caller's telephone number.

When such a call setup procedure is performed, the called party exchange performs the incoming call processing to the called terminal 120, wherein the called terminal 120 uses the caller's unchanged telephone number included in the initial address message. The incoming call of the outgoing call is performed (S519). Accordingly, the destination terminal 120 rings and the incoming phone number is displayed as the caller's phone number instead of the changed phone number as the caller's phone number (S521).

As described above, the information according to the caller ID change indication service subscription is registered in the home location register of the subscriber, and when a call is sent from the subscriber, the caller's telephone number of the caller is changed from the calling party exchange to the called terminal. Is processed. In the embodiment referring to Fig. 4, the originating exchange does not go through the originating home location register when calling, but in the embodiment referring to Fig. 5, the originating exchange is going through the calling home location register. In addition, in the embodiment referring to FIG. 4, the subscriber profile is transmitted to the calling side exchange when the caller's location is registered, and the phone number before the change is also transmitted. In the embodiment referring to FIG. Whenever a call is sent without being sent, the calling home location register will dial the calling number before the change to the calling exchange.

Meanwhile, in the above-described embodiment, the phone number before the change of the caller who changed the phone number has been described as always displayed on the called terminal, but the caller may select the phone number displayed as the caller's phone number. That is, the core network 140, when the originating call containing the function code for the deactivation of the service according to the present invention is received from the originating terminal 110, and deactivates the service. For example, delete trigger information that prevents the originating call from going through an intelligent network, sets service inactivity information in a subscriber profile stored at the originating location's visited location register, or directs all calls to the originating home location register. By registering general trigger information so that the originating call does not go through the originating home location register, a general call processing procedure may be performed so that the caller's current phone number, that is, the telephone number after the change, is displayed on the called terminal.

In addition, the caller who changed the telephone number may deactivate the service and temporarily activate the service as necessary. When an outgoing call including a function code for temporarily activating the service according to the present invention and a called party's phone number is received from the calling terminal 110, the core network 140 once the call before the change of the caller according to the temporary activation function code. Incoming call is processed using the number.

In addition, the caller who changed the phone number can activate the service after deactivating the service. As described above, if the caller has temporarily activated the service once, the service activation in this description is not a temporary activation but a process of continuous service activation such as service deactivation. When an outgoing call including a function code for activating a service according to the present invention is received from the originating terminal 110, the core network 140 performs a service activation process in a process opposite to the above service deactivation process, thereby changing the caller. Make sure that the entire telephone number is displayed on the called terminal.

As another embodiment, the above-described embodiment is described as changing the caller's telephone number without considering the called party's telephone number, but according to the embodiment, it is possible to determine whether to change the caller's telephone number in consideration of the called party's telephone number. That is, when an emergency call such as 112 or 119 is called, the called party may need to confirm the exact location of the caller. The phone number before the change of the caller is displayed as the calling party number, so that the called party may not be able to confirm the caller's exact location. have. Accordingly, in order to prevent such a problem, when the emergency call numbers such as 112 and 119 are called phone numbers, the core network 140 performs incoming call processing using the current phone number instead of the previous phone number. To this end, the core network 140 has a number change exception called party number table.

Further, as another embodiment, if the called party's telephone number of the outgoing call is not an exception number but is not also a mobile telephone number (ie, 01x type number), the core network 140 may call the current telephone number instead of the caller's previous telephone number. The incoming call is received. In the case of a wired terminal, the caller's telephone number display function is not many and additionally, a call that requires additional charging requires a correct caller's telephone number to be charged normally (e.g., 1588 service). Since the call is because the called party's phone number is not the mobile phone number, the core network 140 receives the incoming call using the current phone number instead of the caller's change phone number when the called party's calling party number is not the mobile phone number. Perform the process.

Although the above embodiments have been described with reference to a mobile communication network, it is clear that the same may be applied to a communication network providing caller information display services such as public networks and Internet telephones.

The method of the present invention as described above may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
