The present invention relates to additional services in a communication network environment. More particularly, the present invention relates to a calling number conversion method for converting a calling number into a virtual calling number using an intelligent network.

The recent rapid development of mobile communication technology has rapidly promoted the popularization of mobile communication terminals, transforming our lives so that most ordinary people always carry mobile communication terminals such as mobile phones and PDAs. The mobile communication terminal has an effect of allowing the user to more easily access the communication network while efficiently allocating system resources of the conventional communication system.

In addition, the recent mobile communication service does not only provide a communication service for a voice call, but also provides various additional services suitable for a user's preference. As one of such additional services, an 'additional number' service that allows a subscriber to select and receive a desired phone number by assigning two or more telephone numbers to one mobile communication terminal is widely used. An example of an additional number service provided by a domestic mobile carrier is KTF's Two Number service.

Most mobile communication terminal users use one phone number assigned to one mobile communication terminal. As the structure of society and work becomes complicated, some users need more than two phone numbers. In this case, there is a method of using two or more mobile communication terminals, but a plurality of mobile communication terminals are not only inconvenient to carry, but also need to purchase additional terminals and pay additional fees. However, in the case of using the additional number service described above, two or more plurality of telephone numbers are given to one mobile communication terminal so that subscribers can properly promote their multiple telephone numbers to other users so that they can be used for the purpose or purpose of use. You can select to receive. The additional number may be classified as a work or personal phone number, if necessary, and as an example, the subscriber of the additional number service may select and receive a call to the work phone number or immediately transfer it to a voicemail.

However, in the conventional additional number service, only the additional number can be received and the outgoing telephone number cannot be displayed by the additional number. That is, in the case of an outgoing call in which an additional number service subscriber calls another user, only the original telephone number is displayed on the mobile communication terminal of the user regardless of who the user is.

For this reason, the conventional additional number service has the following problems. For example, when the subscriber of the additional number service informs the other subscriber A of the original telephone number of 'xxx-1000' and another subscriber B of the additional number of 'xxx-2000', the subscriber is the user A. When calling the user, it is not a problem that the subscriber's outgoing telephone number is displayed as 'xxx-1000', which is the original telephone number, in the user A's mobile terminal. However, when the subscriber calls User B, the calling number is not displayed as 'xxx-2000', which is an additional number previously informed to User B's mobile terminal, and the calling number is displayed as 'xxx-1000', the original number. do. In this case, the user B's position is displayed as a calling number different from the informed telephone number, so that the calling subscriber cannot be properly recognized, and the caller's own original number is also exposed to an unwanted user.

In order to solve this problem, even when the caller's caller's number is displayed, techniques have been proposed to allow the caller to display the caller's number as an additional number desired by the caller.

Republic of Korea Patent Application Publication No. 10-2005-0042870 (hereinafter referred to as 870 'patent) is provided with a subscriber information database that stores and manages the mother and child numbers in the home location register of the calling party separately at the time of sending It has been proposed a method of setting any one as a calling number and transmitting it to an exchange.

First, FIG. 1 shows a configuration of a communication network in which the present invention is realized.

As shown in the figure, the system 100 for converting a calling number according to the present invention includes a plurality of wireless subscriber stations 110 located in a communication area allocated in sector units, and wireless communication with the subscriber stations 110. A base station controller (BTS) 121, a base station controller (BSC) 122 controlling the base station 121; Exchanger 130; Visitor Location Register (VLR) 135; NO. 7 network 140; A home location register (HLR) 150; An intelligent network system (IN: Intelligent Network) 160 including an intelligent network service switching point (SSP) 161; and an intelligent network service controller (SCP) 162; Customer management database system 170; Public Switching Telephone Network (PSTN) 180; And a wired subscriber station 110 'connected to a public switched telephone network.

The subscriber station 110 is responsible for the basic call processing and caller ID display function. Subscriber terminal 110 according to the present invention includes a cellular phone, PCS (Personal Communication Service) phone, PDA phone, GSM phone, WCDMA phone, CDMA-2000 phone, DMB phone and the like.

The wired subscriber station 110 ′ is a wired telephone equipped with a caller ID display function and is a terminal of the called party displaying the caller ID information.

The radio access network 120 serves to guarantee the mobility of the subscriber station, and performs hand-off and radio resource management functions. The wireless access network 120 includes a base station 121 and a base station controller 122 so that the subscriber station 110 uses a wireless protocol between the subscriber station 110 and the switch 130. 7 allows access to network 140. In particular, the base station 121 receives an outgoing signal from an originating subscriber station (hereinafter referred to as an originating terminal) using a paging channel or a traffic channel among the signal channels, and transmits it to the base station controller 122. The base station controller 122 controls the base station 121, and assigns and releases radio channels for the subscriber station, transmit power control of the subscriber station and the base station, intercell soft handoff and hard handoff determination, transcoding and Performs vocoding, operation and maintenance of the base station.

The exchange 130 performs basic and additional service processing, incoming and outgoing call processing of the subscriber, location registration procedure and handoff procedure, interworking with other networks, and the like. In addition, the visitor location register 135 temporarily stores the location and subscriber information of the subscriber station located in the communication area of the exchange 130. In addition, when the exchange 130 receives an identification code for requesting calling number conversion service from the subscriber station 110, the exchange 130 performs a call processing from the visitor location register 135 to the intelligent network 160 corresponding to the identification code. Extracts routing information for the call and establishes a call to the corresponding intelligent network 160 according to the information. Here, as an example of the identification code, there may be a method of adding a special number (* 77) before the incoming number. Of course, the identification code according to the invention is not necessarily limited to this example.

The home location register 150 stores and manages subscriber information, additional service information for each subscriber, and location information of a mobile communication terminal. In particular, the home location register 150 stores profile information of the calling and called terminals. This profile information includes the subscriber station's MIN (subscriber phone number), ESN (mobile phone serial number), subscribed telecommunication supplementary service information, and the like. Therefore, the information of the subscriber subscribed to the calling number conversion service according to the present invention is recorded in the profile information. When the exchange 130 does not receive the routing information according to the calling number translation service from the visitor location register 135, the switch 130 receives the corresponding routing information from the home location register 150. That is, after receiving the routing information request signal from the switch 130, the home location register 150 inquires the stored subscriber profile and the additional service information, extracts the corresponding routing information, and delivers the routing information to the switch 130. .

The intelligent network system 160 is a network system that connects a computer to a communication network so that new technologies can be easily incorporated. That is, it is possible to flexibly provide various communication services or supplementary services using a computer by integrating the switch, service control node, and in-network control database scattered in the communication network through the common line signal network or data network. It is an easy system. The intelligent network system 160 includes an intelligent network service exchanger 161 and an intelligent network service controller 162.

The intelligent network service exchanger 161 recognizes the intelligent network service request call transmitted from the exchanger 130 and requests the intelligent network service controller 162 for necessary service control information. In addition, according to the information transmitted from the intelligent network service controller 162 performs a switching function to provide a desired service to the service user and to set up a call to the destination network. When the service request to the intelligent network service controller 162 uses a MAP protocol. The service is requested according to the protocol, and information is provided by loading information on detailed parameters of the protocol in response.

The intelligent network service controller 162 performs control processing of providing a corresponding service or information to a service processing request of the intelligent network service exchanger 161 while retaining detailed information on an additional service or an intelligent network service. The intelligent network service controller 162 stores caller ID conversion service subscriber information and a virtual caller ID that is a caller ID to be converted. Therefore, when the caller ID conversion request is received from the intelligent network service exchanger 161, it is determined whether to subscribe to the service, and in the case of the service subscriber, the virtual caller number is loaded in the detailed parameter according to the protocol. In addition, the intelligent network service controller 162 may easily add, change, or delete a service by using an interface between the subscriber and the intelligent network 160 such as an automatic response system (ARS) or a wired or wireless Internet.

The customer management database system (WISE) 170 stores information on the customer of the service provider. This information includes subscriber information, fee information, additional service information, and the like. It also manages the communication system and adds, changes, and deletes new services and subscriber information. The subscriber subscribes to the calling number conversion service to the customer management database system 170, and when the subscriber subscribes to the calling number conversion service, the information is stored in the customer management database system 170, and the home location register 150 is provided. The information is provided to the intelligent network service controller 162 of the intelligent network 160.

The public switched telephone network 180 enables a wide area communication network to be a network to which a plurality of exchanges are connected. The originating exchange transmits an incoming call to the public switched telephone network 180 according to the routing information, and the incoming call is set to the corresponding destination exchange of the public switched telephone network 180 according to the routing information. In addition, the intelligent network service exchanger 161 of the intelligent network 160 may transmit an incoming call along with routing information to the public switched telephone network 180.

The above-described system of the present invention has been described as a representative embodiment in which the incoming and outgoing subscribers are both CDMA subscribers and the mobile communication network is a CDMA network. However, the system of the present invention is not necessarily limited to such a system.

That is, the system of the present invention is equally applicable to the case where the mobile communication network is a CDMA network, at least one of the incoming and outgoing subscribers is a WCDMA subscriber, and the WCDMA subscriber is roaming in the CDMA network. In this case, the MSC may be replaced with SGSN and the HLR may be replaced with DS-HLR. That is, when the incoming and outgoing subscriber is a WCDMA subscriber roaming in the CDMA network, location information and profile information of the incoming and outgoing subscriber are obtained from the DS-HLR. In addition, of course, the same can be applied to a wired communication network, not a mobile communication network.

Referring to the calling number translation service procedure of the present invention executed based on the system described above is as follows.

The subscriber who wants to use the calling number conversion service according to the present invention uses the wired / wireless internet, or accesses the intelligent network 160 by using an automatic answering system (ARS), and uses his / her subscriber number (for example, MIN or ESN) is set and registered with the virtual call number to be converted. The calling number translation service subscription registration information is stored in the home location register 150 and the intelligent network service controller 162 of the intelligent network 160 that accommodate the corresponding subscriber through the WISE 170. At this time, the virtual call number is stored in the intelligent network service controller 162 of the intelligent network 160, it is possible to easily add, change, delete, etc. by the subscriber.

When the subscriber sends an incoming call including an identification code such as a special number (* 77) to receive a calling number conversion service using his terminal, the calling party exchange 130 managing the calling subscriber receives the identification code. As a result, the home location registerer 150 requests routing information for the call. The home location register 150 receives the call, translates the identification code, recognizes the calling number conversion service request call, and transmits routing information to the calling side exchange 130 to the intelligent network 160 that performs the corresponding service. do. Accordingly, the originating exchange 130 sets up a call to the corresponding intelligent network service exchange 161 according to the received routing information.

The intelligent network service exchanger 161 makes a service processing request to the intelligent network service controller 162 for checking whether the calling number translation service is subscribed and processing the corresponding service. The intelligent network service controller 162 receiving the service processing request determines whether the subscriber subscribes to the calling number conversion service and, if confirmed as the subscriber, adds the virtual calling number registered in advance to the calling party's calling number to the intelligent network service. Return to exchange 161. The intelligent network service exchanger 161 which has received the original calling number and the added virtual calling number is a called network or a called party's exchange according to the called number and includes the called number information replaced with the virtual calling number instead of the original calling number. Forward the call.

Accordingly, the called party exchange establishes a call to the called terminal. In this case, the virtual calling number converted by the intelligent network 160 is displayed in the calling number display information of the called terminal.

In this way, the original calling party number is not displayed on the called party's terminal, but may be displayed as a predetermined virtual calling number, so that the incoming call can be attempted without exposing the unwanted original original phone number. At this time, it is possible to designate and convert a virtual calling number to be converted in advance by using an intelligent network that supports flexible supplementary services, so that the service can be flexibly provided without any special change in the communication network system. In addition, it provides a function that can easily use the service to subscribers.

Hereinafter, a detailed call processing procedure for converting a calling number from a calling terminal to a virtual calling number previously determined at the time of calling based on the system and technical spirit of the present invention described above will be described.

2 is a flowchart illustrating a call processing procedure of a calling number translation service according to an embodiment of the present invention.

Referring to Figure 2, the calling number conversion service procedure according to the present invention, first, the subscriber for receiving the calling number conversion service using the calling party terminal 110, the called number with a special number (* 77) identification code And transmits an outgoing signal to the base station 121. Accordingly, the base station 121 transmits the originating signal to the originating exchange 130 where the originating terminal is located.

Receiving an outgoing signal including an identification code from the originating terminal, the originating exchange 130 recognizes that special routing information is needed by translating the identification code, and sends a routing information request signal (FET_REQ) to the home location register 150. (2)

The home location register 150 extracts routing information corresponding to the identification code from the profile information of the calling subscriber. This routing information is stored in the response message (fet_req [to intelligent network]) transmitted to the source exchange 130 and transmitted to the source exchange 130. (3)

The originating exchange 130 sets up a call to the intelligent network 160 according to the routing information contained in the response message. That is, the call setup message (IAM) is transmitted to the intelligent network service exchanger 161, which is the gateway exchange of the intelligent network 160, to perform call setup to the intelligent network 160. (4)

The intelligent network service exchanger 161 requests the service processing (A.I) according to the intelligent network protocol (MAP) to the intelligent network service controller 162 to process the calling number translation service.

The intelligent network service controller 162 receives the calling number translation service processing request and determines whether the calling subscriber subscribes to the service. To determine whether to subscribe to the service, the subscriber information and the additional service information provided from the customer management database system are used. When the calling subscriber is identified as the conversion service subscriber, a virtual caller number preset by the subscriber is extracted. The virtual call number is provided from the customer management database system or uses information stored and received directly from the subscriber through an automatic response system (ARS) or wired or wireless Internet. The extracted virtual call number is loaded in the new parameter WIN_INFO8 of the intelligent network protocol for transmission to the intelligent network service exchange 161. 3 shows a new parameter loaded with a virtual call number according to the intelligent network protocol. Referring to FIG. 3, in the case of a 10-digit virtual call number, Digit_Length becomes 10, and Digit_11 of Octet6 is peeled by H'F. In the case of an 11-digit virtual call number, Digit_Length becomes 11 and all of Digit_0 to Digit_11 are filled with the virtual call number. The message including the new parameter loaded with the virtual calling number (a.i [win_info8]) is transmitted to the intelligent network service exchanger 161. (6)

The intelligent network service exchanger 161 receiving the virtual calling number replaces the virtual calling number instead of the original calling number, and transmits an incoming call including the calling number information to the called network. In this case, the incoming request message is transmitted using the ISUP parameter, and FIG. 4 shows the definition of the ISUP parameter for transmitting the virtual calling number. Referring to FIG. 4, Octet 1 and 2 in the outgoing call setup ISUP parameter are processed in the same manner as the existing values. After Octet 3, the Address Signal is processed by matching Digits in Win_info8 to replace the virtual signal. At this time, the length of the Digits is checked. The final virtual call number is processed after determining by referring to the Digits_Length in the Win_info8 parameter of FIG. The incoming request (LOR_REQ) is made to the called network, including the outgoing relay ISUP parameter, and the call setup (IAM) is performed.

When the call is set up as a destination exchange of the called network, the called terminal according to the call is displayed by the caller ID service (CNIP). Therefore, the called terminal subscriber can check the virtual calling number other than the original telephone number of the calling subscriber.
