Abstract

PURPOSE: A method and a system for transmitting a call back number of a short message service in accordance with mobile number portability are provided to introduce mobile number portability, so that an SMSC(Short Message Service Center) can transmit a call back number to a short message receiver without an error even after a subscriber number and terminal ID information are different. CONSTITUTION: When a user terminal(110) is powered on(210), MIN(Mobile Identity Number) information is transmitted to an MSC(125)(215). The MSC(125) transmits a subscriber information supply request to an HLR(220), and stores received subscriber information(225). The user terminal(110) transmits a short message to the MSC(125)(230). The MSC(125) transmits subscriber information on a subscriber who transmits the short message to an SMSC(140)(235). The SMSC(140) checks whether a call back number included in the short message is identical with the MIN information of the user terminal(110)(240). If so, the short message is transmitted at a receiver's telephone number designated by a user(245).

Description

METHOD AND SYSTEM FOR TRANSMITTING CALL BACK NUMBER OF SHORT MESSAGE SERVICE ACCORDING TO MOBILE NUMBER PORTABILITY}

The present invention relates to a method and a system for delivering a contact number of a short message service according to number portability, and in particular, to provide a contact number without error even when a user uses another mobile communication service system with an existing phone number by introducing number portability. It relates to a contact number delivery method and system of a short message service according to the number portability.

BACKGROUND OF THE INVENTION Due to the development of science and technology and the improvement of the economic level, the use of a mobile communication terminal for making a telephone service available while on the move is becoming common.

When a specific user subscribes to a specific mobile communication service (e.g., K-Phototel, SK Telecom), he or she is provided with a subscriber number (i.e. phone number) assigned to (or chosen by the subscriber) to a carrier providing the mobile communication service. do.

However, if the subscriber later wants to change to another mobile communication service (eg, SK Telecom, K-Phototel), the existing phone number is no longer available and is assigned a new subscriber number from the new carrier.

The inconvenience of not being able to maintain the existing number has been a factor that prevents the subscriber from switching to a mobile communication service that provides a better service, and as a result was one of the constraints for the smooth operation of the new operator.

Recently, however, the Ministry of Information and Communication has decided to adopt the mobile number portability policy based on the deliberations of the affiliated communication committee in order to enhance customer convenience and promote competition among companies.

Mobile Number Portability generally refers to a provider's portability that can continue to use an existing phone number even if the operator is changed. For example, an existing subscriber who used a phone number of 016-123-4567 as a K-freetel subscriber may register a new service (ie, change of service provider) as a service provider that provides services at a lower price. This will allow you to continue using your existing phone number -123-4567.

As such, the switching cost and mobility barrier that bind customers to operators through the introduction of number portability, which allows subscribers to change operators without changing their numbers, significantly lowers the operator switching and activates operators. It will increase customer convenience and influence competition among operators, such as promoting competition among companies. Therefore, retaining existing subscribers will be a primary marketing core goal for mobile operators and strengthening differentiated customer-oriented competition strategies to gain a competitive edge over competitors.

However, in order to apply the number portability as described above, it is necessary to introduce a separate identifier for distinguishing the subscriber's telephone number from the mobile communication terminal from the viewpoint of the mobile communication service system.

However, in the conventional method of delivering a call back number (SMS) for a short message service (SMS), a telephone number (for example, 016-123) of a mobile communication terminal having a mobile identity number of 10 digits (MIN) is used. -4567) is used as the mobile terminal identifier, so that even after the number portability is applied, it is entered as the MIN of the mobile terminal as the call back number of the short message service (SMS). Unlike the intention, there is a problem to be delivered. When the problem is described in detail, the mobile communication service system recognizes a mobile communication terminal using a mobile identity number (MIN) or an international mobile subscriber identity (IMSI).

The International Mobile Subscriber Identity (IMSI) is a terminal identifier composed of up to 15 digits, and is composed of a terminal country code (MCC), a mobile network number (MNC), and a terminal identification number (MSIN).

Conventionally, the terminal identification number (MSIN) has been used at the same value as the mobile identity number (MIN), and as a result, the MIN may be called a subscriber number (MDN). That is, the telephone number of the customer and the identifier for identifying the corresponding user terminal in the mobile communication service system were the same. Thus, the call back number entered by a particular short message sender while sending a short message to the recipient was either the same number as the MIN or a phone number to be actually contacted. As such, the terminal identification number (MSIN) and MIN (Mobile) Since the Identity Numbers are set and operated in the same way, the Short Message Service Center (SMSC) can send a short message service to the called party without checking whether the call back number entered by the short message sender is the correct number. The SMS contact number could be sent by way of delivery

However, when the number of subscribers and the information for identifying the terminal in the network are changed due to the introduction of mobile number portability, the conventional SMS contact number transmission method can no longer be applied.

That is, as a call back number of a short message service (SMS), a MIN, which is an identifier of a mobile communication terminal that is not an actual use number of the corresponding subscriber, is input and is transmitted differently from the intention of the subscriber.

Accordingly, an object of the present invention is to provide a number portability that allows a short message service center (SMSC) to deliver a call back number to a short message recipient without error even after the subscriber number and terminal identification information are changed according to the introduction of number portability. It is to provide a method and system for delivering a contact number for a short message service.

Another object of the present invention is to contact the short-term service according to the number portability so that the user terminal that can not enter the third party vendor number for the number portability application or change the mobile network number (MNC) information can be continuously used after the introduction of the number portability It is to provide a number transfer method and system.

There is provided a system, apparatus, and recording medium that allows the performance of that data transfer method.

Here, the recipient address and the sender address may be a telephone number, an IP address, an email address, and the like, and the transmission data may be voice data, text data, image data, video data, or the like.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing a short message transmission and reception system according to the prior art.

Currently, mobile communication service providers provide various types of paid services, such as caller ID service, short message transmission / reception service, long message transmission / reception service, and wireless Internet access service, to a mobile communication service subscriber. Among them, a service that can be used most cheaply and secures a wide user base may be referred to as a short message transmission / reception service. Hereinafter, a short message transmission / reception service method according to the prior art will be briefly described with reference to FIG. However, the system configuration of FIG. 1 illustrates only a part of a configuration of a mobile communication service system for performing a short message transmission / reception service, and various devices may be further included.

Referring to FIG. 1, a short message transmission / reception service system includes a base station transceiver base system (BTS) 115, a base station controller (BSC) 120, a mobile switching center (MSC) 125, A home location register (HLR) 130, a visitor location register (VLR) 135, and a short message service center (SMSC) 140. Of course, although not shown in Figure 1 it may further include an authentication center (AC). Of course, the base station (BTS) 115 is a baseband signal processing, wired and wireless conversion, and the transmission and reception of wireless signals, etc. A network termination device that is directly connected to a subscriber station by performing the operation, includes a baseband processor comprising an RF radio processor and a channel and a controller for processing a CDMA signal.

A base station controller (BSC) 120 is a device located between a base station (BTS) 115 and an exchange (MSC) 125 to manage base station management and control. In order to efficiently process CDMA variable voice codes, a packet-switched structure is employed. No. 7 signal system is used for various signal processing.

The exchanger (MSC) 125 is a device for performing basic and additional service processing functions, incoming and outgoing call processing functions of subscribers, location registration and handoff procedure processing functions, interworking functions with other networks of the existing network, and the like.

The home location register (HLR) 130 is a database that stores information on the subscribers of the mobile communication service, and exchanges almost all of the subscriber data, such as when calling from the mobile terminal, registering a location, and receiving a call to the mobile terminal (MSC) 125. It performs a function provided to the visitor location register (VLR) 135 and holds necessary routing information for incoming calls to the user terminals (110a, 110b). In addition, all information and data transmission is applied to N0.7 common line signaling.

The visitor location register (VLR) 135 is a database that registers the locations of user terminals 110a and 110b that are outside of the home network (ie, connected to the Visiting Network). In principle, the user terminals 110a and 110b often announce their location through the base station closest to the current location, and the visitor location register (VLR) 135 has the base station ID closest to the user terminals 110a and 110b. It will be registered. If the user terminal 110a or 110b is not found on the home network when a call is requested, the base station ID registered in the visitor location register (VLR) 135 is found and the user terminal 110a or 110b corresponds to the user terminal 110a or 110b. The short message service center (SMSC) 140 is a system for providing a short message service (SMS), and performs a message input function, a message management function, a message delivery function, and the like.

The short message transmission / reception service method according to the conventional method using the short message transmission / reception system illustrated in FIG. 1 will be briefly described. In the description of the short message transmitting / receiving service method with reference to FIG. 1, the user terminal of the user who transmits the short message is referred to as 110a and the user terminal of the user who receives the short message is referred to as 110b. In addition, although only a mobile communication terminal is illustrated as a type of the user terminal 110 that can use a short message transmission / reception service in FIG. 1, various devices (for example, a computer, a personal digital assistant (PDA), etc.) may be used. It is obvious that the same message can be applied. First, when a short message is transmitted from the user terminal 110a (that is, SMS transmission), the short message is transmitted to the base station (BTS) 115 and the base station controller ( BSC) 120 to the exchanger (MSC) 125.

Switch 125 (MSC) 125 uses a Short Message Delivery Point to Point (SMDPP) message to receive a short message (and subscriber information) corresponding to the recipient (i.e., the recipient of the short message). Transmit to the service center (SMSC) 140. At this time, the MSC 125 transmits the subscriber transmission data SMS_BearerData, the dialed number (ie, the destination number) as the destination address (SMS_Destination Address), and the identification number (MIN) of the calling subscriber terminal as the source address (SMS_Original Originating Address). And a short message including parameters such as an outgoing subscriber's telephone number (MDN) to the short message service center (SMSC) 140. The exchange (MSC) 125 then transmits a short message service center (SMSC) ( When the response message is received from the 140, the response message is transmitted to the user terminal 110a that has transmitted the short message.

Thereafter, the short message service center (SMSC) 140 corresponding to the called subscriber performs the incoming processing on the short message. That is, the short message service center (SMSC) 140 receives the location information of the called subscriber from the home location register (HLR) 130, and then exchanges (MSC) 125, the base station controller (BSC) 120, The short message is transmitted to the user terminal 110b of the receiver via the base station (BTS) 115.

If the user terminal 110b of the receiver is in the unreceivable state, the corresponding information is set by the MSC 125 to set the Pending Flag to '1'. SMS notification to the short message service center (SMSC) 140.

Subsequently, the short message service center (SMSC) 140 resets the pending flag to '0', and then transmits a short message to the corresponding exchange (MSC) 125, resulting in the receiver's user terminal 110b. In addition, if the user terminal 110b of the receiver is powered off, the MSC 125 sets a pending flag to the home location register HLR. After sending to 130, it resets the exchange (MSC) 125.

However, if the user terminal 110b of the receiver is in a callable state, the MSC 125 notifies the short message service center (SMSC) 140 of the information to the SMS message, and the short message is received. When a SMS Notification Ack message is received from the service center (SMSC) 140, the Pending Flag is released, and then a short message is received using the received SMPP message. In order for a specific user terminal 110a (hereinafter referred to as 110b) to be provided with a mobile communication service through a mobile communication service system, a location registration operation of the user terminal 110 by an MSC 125 must be preceded. do. The location registration process of the user terminal 110 will be described briefly as follows.

First, when the power of the user terminal 110 is turned on, the user terminal 110 sends a mobile identification number (MIN), which is a mobile communication terminal identifier, and a terminal unique number (ESN) to a nearby base station (BTS) 115. The base station (BTS) 115 transmits the received message to the exchange (MSC) 125. The exchange (MSC) 125 transmits a MIN, which is a terminal identifier included in the message, to a network ( Compared with all MINs in the network, it is determined whether the corresponding user terminal 110 is connected to a home network or a visitor network. If the corresponding user terminal 110 accesses the visitor network, the exchange 125 (MSC) 125 uses the routing information (that is, the tracking route) stored in the signaling transfer point (STP) to inform the corresponding subscriber. The home location register (HLR) 130 stores the information providing request message.

At this time, the home location register (HLR) 130, after receiving the information providing request message, using the MIN and ESN to determine whether the phone number is a valid number or illegally used number. Thereafter, after registering the location information of the subscriber (ie, the user terminal 110) with the home location register (HLR) 130, the subscriber information (eg, terminal information, etc.) is present in the visitor network. 125).

The exchange (MSC) 125 stores the subscriber information received from the home location register (HLR) 130 present in the home network in the visitor location register (VLR) 135, whereby the subscriber is present in the visitor network. It is possible to receive a mobile communication service such as a telephone call even without passing through an exchange (MSC) 125 provided in a home network.

2 is a data flow diagram illustrating a method of transmitting and receiving a short message according to an exemplary embodiment of the present invention, and FIG. 3 is an exemplary view of a screen display showing a general process of transmitting a short message in a user terminal.

If Number Portability is introduced, which means carrier portability that can continue to use an existing phone number even if the operator is changed, an existing subscriber using a phone number assigned by a specific operator may maintain his / her phone number. You can subscribe to other service providers to receive services. In other words, existing subscribers can sign up as a provider of higher quality services without the inconvenience of changing the phone number.However, if such a number portability is introduced, the existing subscriber has already entered the user terminal. There is a need to modify MIN (Mobile Identity Number) information to MIN information that can be recognized by the new service system. If the MIN information is modified to a form that can be recognized by the new service system (for example, a new subscriber number (MDN), the mobile directory number (MDN), the user still has his own subscriber number (MDN) and identification information of the user terminal ( MIN information) can be kept the same.

However, in the case of an old terminal or a user terminal that cannot modify the International Mobile Subscriber Identity (IMSI) information, the terminal identification information stored in the user terminal may be changed even if the subscriber number (MDN) is changed by the user joining the new operator. There is a problem that the user terminal can not be identified in the new service system because it can not be changed. Therefore, the present invention has been made to solve the problem, and the subscriber's subscriber number (MDN) and terminal identification information (MIN information) By separately managing), it can provide the benefits of number portability regardless of the type of terminal, and also reduce unnecessary call calls by providing accurate call numbers in the process of short message transmission / reception. do.

Such advantages and features of the present invention will be readily understood by reference to the following description made with reference to FIGS. 2 and 3.

Referring to FIG. 2, when the user terminal 110 is switched to a power-on state in step 210, the user terminal 110 proceeds to step 215 to transmit MIN (Mobile Identity Number) information through a wireless communication network. In addition, information transmitted from the user terminal 110 to the exchange (MSC) 125 for registration of its location is transmitted through the base station exchange (MSC) 125. Information is not limited only, and International Mobile Subscriber Identity (IMSI) information may be applied for the same purpose. As described above, the IMSI information is a terminal identifier composed of up to 15 digits, and is composed of a terminal country code (MCC), a mobile network number (MNC), and a terminal identification number (MSIN). ) Consists of the same content as MIN information.

The exchange (MSC) 125 uses the MIN information received from the user terminal 110 in step 220 to store subscriber information (eg, corresponding to the user terminal 110) stored in the home location register (HLR) 130. , MIN information, subscriber number (MDN) information, etc.) transmission request. The home location register (HLR) 130 in step 220 is a home location register provided in a home network corresponding to the user terminal 110.

Thereafter, the exchange (MSC) 125 stores the subscriber information (eg, MIN information, subscriber number (MDN) information, etc.) received from the home location register (HLR) 130 at step 225. Of course, the subscriber information may be stored in a visitor location register (VLR) 135 coupled with an exchange (MSC) 125.

As before, when number portability was introduced, MIN information was generally recognized as the same information as subscriber number (MDN) information. However, after the introduction of number portability, MIN information and subscriber number (MDN) information may be different.

For example, subscribe to A carrier and sign up with a subscriber number (MDN) of 011-234-5678 and IMSI information 40 (terminal country code (MCC))-00 (mobile number (MNC))-0112345678 (terminal identification number ( Suppose that an existing subscriber who had MSIN)) had a new subscription (subscriber number: 016-123-4567) while maintaining an existing phone number with K-Phototel, which provides better service. Also, suppose that the user terminal of the subscriber is a user terminal of a type in which the IMSI information is not modified. In this case, the subscriber's subscriber number (MDN) is 016-123-4567, but the identification information (MIN information) of the user terminal. ) Are different from each other as 0112345678, and it is necessary to separate and manage two different information in a newly subscribed mobile communication service system. The need to separate and manage two different information as described above will be more clearly understood through the following description of the drawings.

Referring to FIG. 2, in step 230, the user terminal 110 transmits a short message input by a user via a base station (BTS) 115 and a base station controller (BSC) 120 through a wireless communication network. The general process of transmitting a short message from the user terminal will be briefly described with reference to FIG. 3.

In general, a user may create a short message to be sent to a recipient by selecting the short message writing button 305 (for example, a function button of an envelope image) of the user terminal 110.

When the user who wants to send the short message selects the short message writing button 305, a new sentence writing screen such as screen 310 is displayed on the display of the user terminal 110.

After the user completes the input of the desired sentence, if the user selects the OK button 315, a display such as 320 is displayed on the display unit of the user terminal 110, so that the user can select the phone number (ie, You can enter the destination number and SMS_Destination Address.

After the user inputs the phone number of the recipient to be transmitted, and selects the OK button 315, the user terminal 110 displays a contact number input screen (that is, a call back number input screen) as shown on screen 330. ) Is displayed.

The phone number inserted and displayed as a default on the contact number input screen as shown in the screen 330 is MIN information input to the user terminal 110. If the user selects the OK button 315 in the state of screen 330 (without modifying the contact number), the MIN information displayed by default is inserted into the short message as the contact number (Call Back Number) and sent to the exchange (MSC) 125. In addition, a message indicating the completion of the transmission is displayed on the display unit 340 of the user terminal 110. That is, when the user transmits the short message without modifying the contact number, the call back number transmitted to the short message service center (SMSC) 140 via the exchange (MSC) 125 is MIN information. In this case, even though the transmission is performed in the related art, since the MIN information and the subscriber number (MDN) coincide with each other, no particular problem occurs.

However, if the number portability is introduced and the MIN information and the subscriber number (MDN) are different as in the above-described case, the contact number included in the short message and transmitted may be displayed as wrong information.

The method proposed by the present invention as a method for solving such a conventional problem will now be described with reference to the related steps in FIG. 2.

Referring to FIG. 2, when a short message is received from the user terminal 110 through step 230, the exchange (MSC) 125 receives subscriber information of the subscriber who transmitted the short message together with the short message (for example, MIN information, subscriber number (MDN), etc.) is transmitted to the short message service center (SMSC) 140.

Upon receiving the short message and subscriber information from the exchange (MSC) 125, the short message service center (SMSC) 140 receives the call back number included in the short message and the corresponding user terminal 110 in step 240. Check whether the MIN information matches. As described above, if the number portability is applied, if the call back number and the MIN information match, the user (ie, the short message sender) defaults to the contact number input step (see screen 330-FIG. 3). It may be the case that the telephone number indicated as (default) is designated as the contact number without modification. Subsequently, in step 250, the short message service center (SMSC) 140 performs the contact number (Call) in a predetermined manner according to the inspection result of step 240. Back Number), the short message is sent to the recipient's telephone number specified by the user.

For example, the following method may be applied to the method of setting a call back number using the contact number included in the short message and the subscriber information in step 250.

First, the short message service center (SMSC) 140 receives the MIN information and the call back number among the subscriber number (MDN), the MIN information, and the call back number received from the switching center (MSC) 125. Checks whether

In the present invention, since the MIN information is used as an identifier of the user terminal, the same subscriber number (MDN) as the MIN information cannot be assigned. When the MIN information and the call back number are the same, there is no called party. do. Therefore, in this case, the subscriber number (MDN) is inserted into the contact number (Call Back Number) to transmit a short message to the user terminal of the receiver. That is, the call back number transmitted from the user terminal of the short message sender is the MIN information, but the call back number transmitted to the user terminal of the short message is the subscriber number (MDN). If the call back number is different, the short message sender modifies and transmits the telephone number (ie, MIN information) indicated as default in the contact number input step (see screens 330 to 3). Send a short message containing the contact number to the recipient's user terminal. That is, the call back number transmitted from the user terminal of the short message sender is recognized as a subscriber number (MDN) or a third contact number.

So far, the method and system for transmitting a contact number of a short message service according to number portability have been described. However, the present invention can be equally applicable to all cases in which it is necessary to transmit a contact number of a sender to a receiver's user terminal such as a contact number of a voice message, a contact number of a multimedia message, etc., in addition to the purpose of delivering a contact number of a short message. Of course.

If the present invention is not connected to a short message service center in order to be applied to a multimedia message transmission and reception method and is immediately connected to a data transmission / reception apparatus located on the Internet, the above-described function of the exchange may be performed by a separate relay device. For example, the above-mentioned caller / destination information such as a transmission / reception telephone number can be variously applied to an e-mail address or an IP address.

In addition, the present invention is not limited to the above embodiment, and many modifications are possible by those skilled in the art within the spirit of the present invention.

As described above, the method and system for transmitting a contact number of a short message service according to the number portability according to the present invention, even after the subscriber number and terminal identification information are changed according to the introduction of the number portability, the short message service center (SMSC) without error is a call number (Call). Back number) to the short message recipient.

In addition, the present invention allows the user terminal that can not enter the third party vendor number for the application of number portability or change the mobile network number (MNC) information can be continuously used after the introduction of number portability.
