The present invention relates to a multi-number service, and more particularly, to a method and system for providing outgoing information for a call that has not been received by a multi-number service subscriber when the multi-number service subscriber is not available.

With the development of mobile communication technology and the increase in the number of wireless subscribers, mobile communication services have recently been developed and provided in addition to simple voice calls. As one of these additional services, a 'multi-number' service that can be used for different purposes by receiving two or more telephone numbers in one mobile communication terminal is widely used. An example of a multi-number service provided by a domestic mobile carrier is KTF's Two Number service.

Subscriber to the multi-number service can display the telephone number (hereinafter referred to as the basic telephone number) assigned at the time of first mobile communication service subscription to the called party's terminal as caller information, and additionally assigned additional telephone number to the called party's terminal Can be displayed as caller information. In addition, the multi-number service subscriber can selectively receive the incoming call to the terminal. For example, when an incoming call flowing into the terminal is received at its primary telephone number, the terminal of the multi-number service subscriber displays general caller information. However, if the incoming call flowing into the terminal is called to the additional telephone number of the subscriber, the terminal of the subscriber displays the caller's information together with an icon indicating that the incoming call is coming from the additional telephone number (or the caller information on the terminal). With additional phone numbers). The subscriber of the multi-number service receives the call selectively based on the caller information displayed on his terminal.

On the other hand, when the called terminal does not receive the incoming call because the power of the called terminal is currently turned off or in a call, a service for providing outgoing call information of the non-receiving call is provided to the called terminal when the called terminal becomes available. For example, KTF's catch call service. The called party can check what kind of call was made in the unavailable state of the call based on the outgoing call information provided by the called terminal, and, if necessary, can make a direct call based on the outgoing call information. On the other hand, by providing the call information of the incoming call to the called terminal can reduce the hassle of the caller unnecessarily attempt to re-call.

By the way, the call forwarding information providing service of the non-receiving call is provided for the basic telephone number in the multi-number service in which a plurality of telephone numbers are assigned to one mobile communication terminal, but not for the additional telephone number. For example, if a caller attempts to dial an additional number of a multi-number service subscriber, but the called terminal of the multi-number service is in a call-free state, when the called terminal becomes available, the call is made to the called terminal. Information is provided. However, it is not possible to distinguish whether the calling information is received by the basic telephone number or by the additional telephone number.

The present invention has been proposed to solve the above problems, and provides a method and system for providing outgoing information for a call that has not been received by a multi-number service subscriber when the multi-number service subscriber is not available. have.

There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a network configuration of a mobile communication system that provides outgoing call information of an unreceivable call in a multi-number service according to an embodiment of the present invention.

As shown in FIG. 1, the mobile communication system according to the present invention includes mobile communication terminals 110 and 120, a base station 130, a base station controller 140, a switch 150, an intelligent network system 160, and a home location. The registrar 170 and the short message service center 180 (hereinafter, SMSC) are included.

Here, it is assumed that the mobile communication terminal 110 is a terminal of a subscriber to a multi-number service, and the mobile communication terminal 120 is a terminal of a general subscriber. The mobile communication terminals 110 and 120 may be used as long as they can connect to the mobile communication system to perform basic voice call processing. At this time, the terminal 110 of the subscriber to the multi-number service may store a plurality of telephone numbers assigned to the subscriber in the terminal and provide an independent interface for each stored telephone number.

The base station (BTS, 130) is connected to the mobile communication terminal (110, 120) in a wireless section to control the mobile communication terminal (110, 120) and connect the call channel, the call originating from the mobile communication terminal (100, 120) It receives and transmits to the base station controller (BSC) 140. The base station controller 140 controls the base station 130, and assigns and releases radio channels to the mobile communication terminals 100 and 120, transmit power control of the mobile communication terminals 100 and 120 and the base station 130, and inter-cell software. It performs handoff and hard handoff determination, transcoding and vocoding, and operation and maintenance functions for the base station 130.

The exchange (MSC) 150 performs basic and additional service processing, incoming and outgoing call processing of subscribers, location registration procedure and handoff procedure processing, and interworking with other networks, that is, public or intelligent network system 160.

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 switching point (SSP) 161 and an intelligent network service controller (SCP) 162.

The intelligent network system 160 stores and manages subscription information of the multi-number service subscriber, and stores and manages additional phone numbers by mapping additional phone numbers to basic telephone numbers of the multi-number service subscriber. When a user calls the additional phone number of the multi-number service subscriber, the intelligent network system 160 changes the additional phone number included as the called party's phone number in the user's outgoing call to the default phone number and then multi-number service. Incoming call to subscriber's terminal.

Meanwhile, the home location register (HLR) 170 is a database that stores service profiles related to subscriber information, and includes a mobile identification number (MIN: Mobile Identification Number) of the mobile communication terminals 110 and 120, and a terminal unique number (ESN). Electronics Serial Number) and service type. In particular, the home location register 170 stores subscription information of the multi-number service subscriber. In the case of the home location register 170 accommodating additional telephone numbers, the home location register 170 adds a multi-number flag field to the subscriber DB to provide the multi-number service subscriber. Manage.

The SMSC 180 sends outgoing information in a text message for a call that has not been received by the multi-number service subscriber. That is, when the destination terminal 110 of the multi-number service is available to call, the message is notified that the missed call to the destination terminal 110. In this case, the SMSC 180 may insert and transmit an identification code indicating that the call is filtered by the additional number into the SMS message. Meanwhile, the SMSC 180 may include a database having information of a basic telephone number of a multi-number service subscriber and additional telephone numbers corresponding thereto.

Hereinafter, a method of providing outgoing information on an incoming call in the mobile communication system shown in FIG. 1 will be described in more detail with reference to FIGS. 2 to 3.

2 is a flowchart illustrating a method for providing outgoing call information of an unreceivable call in a multi-number service according to an embodiment of the present invention, in which a general subscriber calls an additional phone number of a multi-number service subscriber or a terminal of a multi-number service subscriber. This is an example of power off.

As shown in Figure 2, the general subscriber enters the additional phone number of the multi-number service subscriber to the calling party's telephone number to the calling terminal 120 and enters a call button to call (S201).

The originating switch 150 receiving the outgoing call requests routing information from the originating home location register 170 accommodating the additional telephone number (S203). At this time, the calling side exchange 150 transmits the calling party's telephone number and the called party's telephone number (ie, the additional telephone number of the multi-number service subscriber) to the calling home location register 170.

The originating home location register 170 that has received the routing information request responds to the originating exchange 150 with routing information (S205). At this time, the originating home location register 170 inquires routing information based on the called party's telephone number transmitted from the calling side exchange 150. The called party's telephone number transmitted from the calling side exchange 150 is a multi-number service subscriber. Since it is an additional telephone number of, the routing information to the intelligent network exchange 161 is returned to the originating exchange 150. To this end, the originating exchange 150 accepting additional telephone numbers manages the multi-number service subscriber information by adding a multi-number flag field to the subscriber information.

The originating exchange 150 connects to the intelligent network exchange 161 according to the routing information from the originating home location register 170 (S207). At this time, the calling side exchange 150 transmits the calling telephone number, called telephone number (ie, additional telephone number) to the intelligent network switch 161.

The intelligent network switch 161 requests the intelligent network service controller 162 whether the called party subscribes to the multi-number service for the outgoing call transmitted from the originating exchange 150 (S209). If the called party's telephone number (i.e., the additional telephone number) subscribes to the multi-number service, the intelligent network service controller 162 determines the called party's primary telephone number based on the called party's telephone number (i. Inquire (S211). To this end, the intelligent network service controller 162 stores and manages a table in which the information of the multi-number service subscriber and additional telephone numbers are mapped to the subscriber's basic telephone number.

Subsequently, the intelligent network service controller 162 changes the called party's telephone number to the basic telephone number and transmits it to the intelligent network switch 161 (S213). The intelligent network switch 161 requests the location information of the called side exchange 150 to the called side home location register 170 that receives the basic telephone number of the called party for establishing a call with the called side exchange 150 (S215). At this time, the intelligent network switch 161 is the called party's home location register 170, the basic telephone number of the called party (ie, multi-number service subscriber) and the calling terminal 120 is added to the called terminal 110. Send an identifier (hereinafter referred to as multi-number identifier, additional number = ON) to try to call the telephone number.

By the way, when the called terminal 110 is powered off (S217), the power-off state of the called terminal 110 is registered in the called home position register 170. Accordingly, the called party home location register 170 recognizes that the called terminal 110 is turned off, and transmits a location information response message including the state of the non-call status of the called terminal 110 to the intelligent network switch 161. (S219). The intelligent network switch 161 releases the call with the originating terminal 120 through the originating exchange as the call of the called terminal 110 is not possible (S221).

On the other hand, the destination home location register 170 requests the SMSC 180 to provide the outgoing information (S223). At this time, the called party home location register 170 transmits the caller's telephone number, the basic telephone number of the called party (ie, the multi-number service subscriber) and the multi-number identifier (eg, additional number = ON) to the SMSC 180.

The SMSC 180 creates and stores an outgoing information message using the caller's telephone number, the primary telephone number of the called party (ie, the multi-number service subscriber) and the multi-number identifier (eg, additional number = ON) (S225). . The SMSC 180 transmits an outgoing information message to the called terminal 110 when the called party can make a call (S227).

However, in step S227, an additional telephone number may be set and transmitted to the called party (that is, the multi-number service subscriber) telephone number of the outgoing information message. To this end, the SMSC 180 includes a database having a basic telephone number of a multi-number service subscriber and an additional telephone number corresponding thereto. The receiving terminal receiving the outgoing information message has an additional phone number set in the called party's phone number of the outgoing information message, so that the called party can recognize that the incoming message is a message introduced to the additional phone number (for example, , [B]) is displayed on the screen of the calling information message.

Meanwhile, in step S227, a basic telephone number of a called party (ie, a multi-number service subscriber) may be set and sent to the called party's telephone number of the outgoing information message. At this time, an identification code indicating that the message is transmitted to the additional phone number is inserted into a specific field of the outgoing information message and transmitted to the called terminal. Since the called terminal receiving the call information message includes an identification code in the call information message, an identification code for allowing the called party to recognize that the received message is an incoming message to an additional telephone number (for example, [B]). Is displayed on the screen of the calling information message.

3 is a flowchart illustrating a method of providing outgoing call information of an incoming call in a multi-number service according to another embodiment of the present invention, in which a general subscriber calls an additional phone number of a multi-number service subscriber or a terminal of a multi-number service subscriber. This is an example of not answering a call.

As shown in FIG. 3, the general subscriber enters an additional phone number of the multi-number service subscriber as the called party's telephone number to the calling terminal 120 and inputs a call button to make a call (S301).

The originating switch 150 receiving the originating call requests routing information to the originating home location register 170 accommodating the additional telephone number (S303). At this time, the calling side exchange 150 transmits the calling party's telephone number and the called party's telephone number (ie, the additional telephone number of the multi-number service subscriber) to the calling home location register 170.

The originating home location register 170 receives the routing information request and transmits routing information to the originating exchange 150 (S305). At this time, the originating home location register 170 inquires routing information based on the called party's telephone number transmitted from the calling side exchange 150. The called party's telephone number transmitted from the calling side exchange 150 is a multi-number service subscriber. Since it is an additional telephone number of, the routing information to the intelligent network exchange 161 is returned to the originating exchange 150. To this end, the originating exchange 150 accepting additional telephone numbers manages the multi-number service subscriber information by adding a multi-number flag field to the subscriber information.

The calling side exchange 150 connects to the intelligent network switch 161 according to the routing information from the calling side home location register 170 (S307). At this time, the calling side exchange 150 transmits the calling telephone number, called telephone number (ie, additional telephone number) to the intelligent network switch 161.

The intelligent network switch 161 requests the intelligent network service controller 162 whether the called party subscribes to the multi-number service for the outgoing call transmitted from the originating exchange 150 (S309). If the called party's telephone number (ie, additional telephone number) is subscribed to the multi-number service, the intelligent network service controller 162 determines the called party's primary telephone based on the called party's telephone number (ie, additional telephone number) included in the outgoing call. The number is inquired (S311). To this end, the intelligent network service controller 162 stores and manages a table in which the information of the multi-number service subscriber and additional telephone numbers are mapped to the subscriber's basic telephone number. The intelligent network service controller 162 changes the called party's telephone number to the basic telephone number and transmits it to the intelligent network switch 161 (S313).

Subsequently, the intelligent network switch 161 requests location information of the called side exchange 150 to the called side home location register 170 that receives the called party's basic phone number for establishing a call with the called side exchange 150 (S315). ). At this time, the intelligent network switch 161 to the called party's home location register 170, the telephone number of the caller and the basic telephone number of the called party (ie, the multi-number service subscriber), the calling terminal 120 and the multi-number identifier (eg, additional number). = ON).

At the request of the intelligent network switch 161, the called party home location register responds with the location information of the called party switch (S317). The intelligent network exchange 161 transmits a call setup message to the called side exchange 150 according to the location information response from the called party home location register 170 and requests a call setup (S319). In response to the call establishment request of the intelligent network exchanger 161, the called party exchanger 150 requests the call establishment to the called terminal 110 (S321).

When the called terminal 110 does not respond to the call establishment request of the called party exchange 150 for a predetermined period of time (S323, for example, when the call is released or the battery is forcibly released), the called party exchange 150 requests the call release to the intelligent network switch 161 (S325), the intelligent network switch 161 via the calling side switch 150 in response to the call release request of the destination side exchange 150, the originating terminal 120 Release the call with) (S327). At the same time, the intelligent network switch 161 requests the called party's home location register 170 to provide outgoing information of the called terminal 110 (S329). At this time, the intelligent network switch 161 together with the called party's home location register 170, the caller's telephone number, the primary telephone number of the called party (ie, the multi-number service subscriber), and a multi-number identifier (eg, additional number = ON). send.

Next, the called party home location register 170 requests the SMSC 180 to provide outgoing information (S331). Similarly, called party home location register 170 transmits the calling party's telephone number, the primary telephone number of the called party (ie, the multi-number service subscriber), and the multi-number identifier (eg, additional number = ON) to SMSC 180.

The SMSC 180 creates and stores an outgoing information message by using the caller's phone number, the primary telephone number of the called party (ie, the multi-number service subscriber) and the multi-number identifier (eg, additional number = ON) (S333). . The SMSC 180 transmits an outgoing information message to the terminal of the multi-number service subscriber if the called party can make a call (S335).

In step S335, an additional telephone number may be set and transmitted to the called party (ie, the multi-number service subscriber) telephone number of the outgoing information message. To this end, the SMSC 180 includes a database having a basic telephone number of a multi-number service subscriber and an additional telephone number corresponding thereto. The receiving terminal receiving the outgoing information message has an additional phone number set in the called party's phone number of the outgoing information message, so that the called party can recognize that the incoming message is a message introduced to the additional phone number (for example, , [B]) is displayed on the screen of the calling information message.

Meanwhile, in step S335, a basic telephone number of a called party (ie, a multi-number service subscriber) may be set and sent to the called party's telephone number of the outgoing information message. At this time, an identification code indicating that the message is transmitted to the additional phone number is inserted into a specific field of the outgoing information message and transmitted to the called terminal. The called terminal receiving the calling information message includes an identification code in the calling information message so that the called party can identify the incoming message as an incoming message to the additional telephone number (eg, [B]). Display on the screen of outgoing information message.

As described above, the multi-number service subscriber who has received the outgoing information message for the unreachable call can check when and who called his additional phone number through the outgoing information message.

Meanwhile, according to the embodiment, the called party, that is, the terminal of the multi-number service subscriber may be a terminal providing an independent interface for each phone number stored therein. That is, the basic telephone number assigned when the mobile communication service is first subscribed is stored in the internal memory, and additional telephone numbers assigned from the mobile communication network are stored in the internal memory when subscribing to the multi-number service. It may be a providing terminal. In this case, the terminal of the multi-number service subscriber independently manages a background screen, a ringtone, vibration / light emission, a call log, an address book, an outgoing / receiving message, a camera album, etc. for each basic phone number and additional phone numbers. Therefore, in the case of a call made with the main phone number, the call log is stored in the call log storage box corresponding to the base phone number. In the case of a call made with the additional phone number, the call log is stored in the call log storage box corresponding to the additional phone number. do. The same is true for text messages.

As such, when the terminal of the multi-number service subscriber is a terminal that independently provides an interface according to the telephone number, in steps S227 and S335, the SMSC 180 includes the caller's telephone number and the called party (ie, the multi-number service subscriber). Create the outgoing information message using the default phone number in and insert a code indicating that the outgoing information message is the call to the additional phone number in a specific field, or set the incoming phone number as the additional phone number of the multi-number service. The number is sent to the subscriber of the service subscriber. The terminal of the multi-number service subscriber stores the outgoing information message in the message storage box corresponding to the additional phone number when the code inserted in the specific field of the outgoing information message exists or the called phone number is the additional phone number. The subscriber of the multi-number service can check the outgoing information message stored in the message storage box corresponding to the additional telephone number to determine when and who called the additional telephone number.

4 is a block diagram showing the configuration of a mobile communication terminal providing a multi-interface according to an embodiment of the present invention.

Referring to FIG. 4, a mobile communication terminal providing a multi-interface according to the present invention includes a communication unit 410 for transmitting / receiving wireless data with a mobile communication system, a control unit 420 for handling incoming / outgoing calls, and user's. An input unit 450 for receiving an input signal, a display unit 440 for displaying information to a user, an interface unit 430 for providing various terminal functions to the user, and a memory 460 for storing and managing data.

The communication unit 410 connects to a base station of a mobile communication system and performs a function of transmitting / receiving and communicating wireless data. The communication unit 410 communicates with the base station through a pilot channel, paging channel, traffic channel, and the like.

The controller 420 drives the terminal, controls the overall work processing of the terminal, and handles and connects the mobile communication system to / from the call call through the communication unit 410. In addition, in conjunction with the interface unit 430, various programs in the terminal are executed and data is input / output into the memory. In addition, the controller 420 stores and sets the additional telephone number received from the mobile communication system through the communication unit 410 in a specific area of the memory.

The input unit 450 receives a voice of a micro user, and receives a signal for operating a terminal from a user using an input means such as a keypad.

The display unit 440 provides the user with the information processed in the terminal. The display unit 440 is a liquid crystal display for displaying the processing state of the terminal on the screen, a light emitting lamp for transmitting information through light emission of the light emitting device, a vibration device for transmitting information through the vibration of the vibration motor, through a ring tone or sound Loudspeakers and the like that convey information by sound.

The interface unit 430 functions to help the user to easily use the basic functions and various additional functions of the terminal. The interface unit 430 includes a first interface 431, a second interface 432, and a switching unit 433. In the present embodiment, it is described that physically configuring one interface unit 430 and the interface unit 430 provides multiple interfaces. However, according to the exemplary embodiment, multiple interface units may be configured independently of each other. Make sure it can be provided.

The first interface 431 is an interface corresponding to the basic telephone number assigned to the terminal, and sets an independent screen and allocates an independent storage area to the memory 460 to be described later. Store and access data in this area and manage data. In the first interface mode, when a user attempts to call an additional phone number, the user inserts an identification number (for example, * 77) directly into the called party's phone number and sends the call. In this case, it is preferable that the first interface 431 stores the call record in the second memory area 462 managed by the second interface 432, and the call record can be confirmed only in the second interface mode. Do.

The second interface 431 is an interface corresponding to the additional telephone number additionally assigned to the terminal according to the multi-number service. The second interface 431 also has an independent screen, and an independent storage area is allocated to store and manage data related to additional telephone numbers. In particular, the second interface 431 automatically adds an identification code to the called telephone number at the time of origination. This is to enable the aforementioned mobile communication system to display caller information with an additional phone number according to a multi-number service. Thus, when the call is made while the second interface 431 is activated, the caller information of the additional telephone number is displayed on the called terminal without any special action.

In addition, the interface settings 431 and 432 are set independently of terminal setting values such as a background screen, a ringtone, and vibration / light emission. This means that depending on the basic phone number and the additional phone number, the background picture, the ringtone, and the vibration / light emission are applied independently of each other. In addition, each of the interfaces 431 and 432 displays a reception indication of a message (a short message or a multimedia message) differently. As described above, each interface 431, 432 refers to a specific field of the received message, recognizes to which phone number the message is received, and receives the message received in the memory area of the interface corresponding to the corresponding phone number. Save it. The message receiving icon of the corresponding phone number is displayed.
