The present invention relates to a mobile telecommunication supplementary service. In particular, when a mobile telecommunication subscriber does not want to answer a phone call during a meeting or personal circumstances, an incoming call is blocked at the request of a subscriber, but a short message service (SMS) is provided. Service) relates to a method and system for providing an absentee service (aka, Only SMS service) that makes it possible.

In general, when a mobile communication terminal is used, it is difficult to immediately receive an incoming call while driving a vehicle, and even if a call is received, accidents are frequently caused to regulate a call while driving. In addition, a mobile communication terminal user may have difficulty in answering or not wanting to receive a call due to personal circumstances such as consulting a customer or attending a meeting or watching a performance.

When it is difficult to answer the call as described above, the mobile phone user can turn off the mobile phone or switch to the etiquette mode (or vibration mode). However, when the subscriber turns off the mobile phone, there is anxiety that he may not receive an urgent call or may be mistaken for intentionally turning off the mobile phone. Even when the phone is switched to etiquette mode, the phone user continues to be nervous and hasten because the phone vibrates continuously when a call comes in.

A user who has difficulty receiving a call can activate the voicemail (VMS). If the voice mailbox is activated, the calling party can recognize the absence of the called party and record the message to be sent to the called party in voice form. Can be. However, there is a hassle that the called subscriber has to access the voice mailbox for checking the voice message, and there may be some time difference between the voice message recording and the voice message checking.

In the event that it is difficult or does not want to answer the call, the subscriber may use the missed event notification method. One of the methods for reporting absence status according to the prior art is disclosed in Patent Application No. '10 -2001-0012474 'published on September 16, 2002 (name of invention:' Method and system for notification of absence status of mobile communication subscriber '). It is. This is because when a mobile subscriber is unable to attend a meeting or take a call, such as watching a movie, the subscriber presses a predetermined key to access the voice message center and stores a voice message for notifying that he or she is away. It is a technology that enables the caller to know the absence of a phone call. According to this conventional technique, when the calling terminal calls the called terminal, the mobile switching system sends a situation notification message preset in the voicemail system to the calling terminal. As a result, the calling terminal can listen to the status notification message of the called terminal and can recognize the receiving side situation.

However, the above-mentioned and missed situation notification method has an advantage of knowing the absence status of the receiving side from the caller's point of view, but has a disadvantage of not being able to identify the caller or accessing the voice mailbox system to verify the caller.

Therefore, if you do not want to answer the call or difficult to answer the call is blocked, but the service that can call the caller information is urgently requested.

Accordingly, the present invention is to solve the above problems, if the mobile communication subscribers are difficult to answer the call or do not want to answer the call, but the phone call reception is blocked without turning off the mobile phone, SMS text messages or outgoing subscribers The information is to provide a recording medium recording a method for the absence service by the subscriber request to receive and a computer program for performing the same.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

1 is a block diagram of a mobile communication system for implementing a missed service by a subscriber request according to an embodiment of the present invention. Referring to this, the mobile communication system includes a base station (BS) 121, 122, an exchange station 131, 132, a short message service center (SMC) 140, and a home location register (HLR) 150. Include.

The mobile communication terminals 111 and 112 are communication terminal devices that allow a mobile communication subscriber to communicate with other communication terminals using a mobile communication network. Base stations 121 and 122 are not specifically illustrated in FIG. 1, but include a base station transceiver (BTS) and a base station controller (BSC).

A base station transceiver (BTS) (not shown) is responsible for the air interface function with the mobile communication terminals (111, 112). A base station controller (BSC) (not shown) controls a plurality of base station transceivers (BTSs) and provides an interface function between the switching centers 131, 132 and the base station transceivers (BTSs).

The switching centers 131 and 132 process call and call from each base station 121 and 122. That is, it is in charge of switching function for call processing and provides an interface function with other network (for example, PSTN: Public Switched Telephone Network).

The home location register 150 includes a database (DB) that stores / manages information of mobile subscribers and is connected to the switching centers 131 and 132. When the call connection request is received by the mobile subscriber, the home location register 150 provides the switching center with information such as whether the mobile subscriber is a valid subscriber, service information set for the mobile subscriber, and location information of the mobile subscriber.

The home location register 150 has a field for indicating whether the missed service is activated for each mobile subscriber or for each missed service subscriber in order to provide the missed service according to the present invention.

The short message service center 140 stores and delivers a short message.

2 is a block diagram illustrating an example of an internal configuration of the home location register 150 shown in FIG. 1. Referring to this, the home location register 150 includes a feature code analysis unit 151, a missed service control unit 153, an exchange station interface unit 155, an SMC interface unit 157, and a subscriber information DB 159.

The subscriber information DB 159 stores / manages mobile communication subscriber-specific information such as a phone number, location information, additional service information, and the like. The subscriber information DB 159 preferably includes a missed service field for each mobile subscriber in order to activate / deactivate the missed service according to the present invention.

The switching center interface unit 155 is responsible for the interface function with the switching center. In particular, the switching center interface unit 155 receives a feature registration / release request signal transmitted from the switching center, and transmits a feature code included in the received signal to the feature code analysis unit 151 to interpret the feature code. The feature code analysis unit 151 analyzes the received feature code, so that the corresponding service can be activated / deactivated. For example, if the received feature code is a predefined code for activating the missed service, the missed service controller 153 controls the missed service to be activated by setting the missed service field of the corresponding mobile communication subscriber to a predetermined value. Also, for example, if the received feature code is a predefined code for the missed service deactivation, the missed service controller 153 controls the missed service to be deactivated.

The SMC interface unit 157 is responsible for the interface function with the SMC (140 in FIG. 1). In particular, the SMC interface unit 157 transmits a short message including outgoing subscriber information (for example, outgoing subscriber number) to the called subscriber when the incoming call comes to a subscriber whose missed service is activated. ).

3 is a flowchart illustrating a missed service activation method according to an embodiment of the present invention. Referring to FIG. 3 and FIG. 1, the missed service activation method according to an embodiment of the present invention will be described as follows.

First, when the mobile subscriber inputs a predefined series of key signals for the missed service request by using the terminal (assuming 112 in FIG. 1), the terminal 112 transmits an outgoing signal to the calling exchange 132. (S310). A series of key signals predefined for the missed service request may be defined as, for example, 'SMS_FC, SEND'. Here, SMS_FC is a feature code (hereinafter referred to as FC for missed service) for identifying the missed service according to the present invention and may be a kind of additional service identification code. SMS_FC is preferably set to '* 0', specifically, '* 0' for activating the missed service according to the present invention, and '* 00' for releasing (deactivating) the missed service according to the present invention. It is preferable to be set. In addition to '* 0', a series of numbers and / or letters may be further included, and the mobile communication service provider may designate in advance so as to be distinguished from a feature code for identifying an existing service.

Then, the originating switching center 132 receives the call origination signal including 'SMS_FC' through the base station 122 (S310). The originating switching center 132 transmits the feature registration request signal FEAT_REQ to the home location register 150 when the received call originating signal includes 'SMS_FC' (S312). At this time, when the originating switching center 132 receives the call originating signal from the terminal, it translates the number included in the call originating signal, and if the number starts with a specific value, for example, '*', the feature registration request signal (FEAT_REQ) Is preferably sent to the home location register.

The home location register 150 sets the missed service field corresponding to the user of the terminal 112 to a predetermined value in response to the feature registration request signal FEAT_REQ of the switching center 132, thereby providing the missed service to the corresponding mobile communication subscriber. Activate (S314). After activating the missed service for the subscriber, the home location register 150 transmits a response signal (feat_req_rr) to the switching center 132 (S316). The response signal feat_req_rr preferably includes information specifying a response tone. Switching station 132 provides a confirmation tone to the terminal 112 in response to the response signal (feat_req_rr) (S318), allowing the subscriber to know that the missed service is normally activated.

3 illustrates only the missed service activation method according to an embodiment of the present invention, but the missed service deactivation method may also be the same as the flow of FIG. 3. However, the feature code for activating the missed service may be different from the feature code SMS_FC for activating the missed service. Of course, the feature code for activating / deactivating the missed service may be the same so that the missed service activation and deactivation may be set in a toggle form.

4 is a flowchart illustrating a missed service providing method according to an exemplary embodiment of the present invention. 4 is a call from a calling terminal (mobile communication terminal) (assuming 111 in FIG. 1 is a calling terminal) to which a terminal with missed service is activated (assuming 112 in FIG. 1 is a terminal in a missed service activation state). It is a case where a call is sent to the side.

1 and 4 together, the user of the calling terminal 111 designates the telephone number of the missed service terminal 112 as the called phone number and sends the call (S410). Of course, the user of the originating terminal 111 may have no idea whether the called party is an absent service subscriber or the missed service is activated. When the originating exchange station 131 receives the call origination signal transmitted from the originating terminal 111, it requests the location information of the called terminal 112 to the home location register 150 (S412). That is, the source switching center 131 transmits the location information request signal LOC_REQ to the home location register 150 in order to obtain the location information of the called subscriber (S412). The location information request signal LOC_REQ includes information of the called party (eg, called phone number) and caller information (eg, called phone number).

When the home location register 150 receives the location information request signal LOC_REQ, the home location registerer 150 searches the subscriber information DB to determine whether the missed service is activated (S414). Specifically, the home location registerer 150 may check whether the missed service field of the called party is activated by checking whether the missed service field of the called party is set to a predetermined value. As a result of the check, if the missed service is activated for the called subscriber, the home location register 150 transmits a response signal loc_req_rr to the originating switching center 131 in response to the location information request. At this time, the response signal (loc_req_rr) to the location information request includes an announcement list for specifying a response message (that is, the missed service response message).

An example of an announcement list is shown in FIG. 6.

Referring to FIG. 6, the announcement list includes an announcement code parameter (ie, a response message parameter). The announcement code parameter defines the announcement or tone to be provided to the caller or subscriber. The length of the announcement code parameter is variable and preferably at least 1 octet. If Standard Announcement or Custom Announcement is specified in the Announcement List, Standard Announcement or Custom Announcement The tone takes precedence over the Tone. If the Standard Announcement or Custom Announcement is not specified or invalid, the tone is applied.

When the originating switching center 131 receives the response signal loc_req_rr of the home location register 150 (S416), the originating switching center 131 reproduces the response message (information broadcast) designated by the announcement code parameter included in the response signal. Provide the missed service response message to the terminal (S418). That is, the originating switching center 131 provides the missed service response message to the calling terminal 121 instead of allowing a call to be connected between the calling terminal 121 and the called terminal 122. To this end, a response message parameter for designating the missed service response message and a corresponding response message need to be predefined in advance. Customers who are now resident in a telecommunications service provider can set up out-of-office service response messages uniformly, as they can only receive SMS at this time. In addition, the missed service user can set his own response message.

The home location register 150 also sends a signal INFODIR requesting short message transmission to the short message service center (SMC) 140 (S420). The short message transmission request signal INFODIR includes the calling terminal information and the called terminal information. In response to the short message transmission request (INFODIR) of the home location register 150, the SMC 140 creates a short message including the calling terminal information, for example, the calling terminal's telephone number, and sends an SMS transmission request to the destination switching center 132. Send a signal (SMDPP) (S424). Then, the destination exchange station 132 transmits a short message including caller information to the corresponding destination terminal 112 through SMS paging (S426). In addition, the destination switching center 132 sends a response signal (smdpp) to the SMC 140 for the SMS transmission request (S428).

Steps S410 to S426 are flows when a call incoming request comes to a terminal in which the missed service is activated. In this case, the calling terminal 111 cannot make a call with the called terminal 112, but can create a short message and send it to the called terminal 112. Processes for transmitting the short message from the calling terminal 111 to the called terminal 112 are shown in steps S430 to S440.

When the user creates a short message in the calling terminal 111 and designates the called terminal as the called party (S430), the sending exchange station 131 transmits an SMS transmission request signal (SMDPP) to the short message service center 140. (S432), the short message service center 140 sends an SMS transmission request signal (SMDPP) to the destination exchange station 132 (S434), and the destination exchange station 132 sends the corresponding short message to the destination terminal 112. It is to be transmitted (S436).

On the other hand, the destination exchange station 132 transmits a response signal (smdpp) for the SMS transmission request to the short message service center 140 (S438), and the short message service center 140 again sends a response signal (smdpp) to the originating exchange station. Transfer to 131 (S440).

These steps S430 to S440 are the same as the normal short message transmission process.

As described above, when a call origination signal to the called party is received by the mobile subscriber with the missed service activated, the call connection to the mobile subscriber is blocked by the mobile communication system, and instead, the missed service response message is sent to the calling terminal. Is provided. In addition, a short message including calling terminal information (for example, a phone number of the calling terminal) may be transmitted to the mobile subscriber who has the missed service activated. In addition, when the calling terminal user needs to make an urgent contact, a short message may be created and transmitted to the mobile communication subscriber having the missed service activated.

Therefore, the mobile communication subscriber who is difficult to answer the call due to personal circumstances can activate the missed service by pressing a feature code for the missed service such as '0' (which can be arbitrarily defined by the service provider). When the missed service is activated, the mobile subscriber can be blocked from receiving the call without turning off the mobile phone and receive the SMS text message or the caller ID. If you want to deactivate the missed service, you can make a normal call call by sending '* 00' (which can be arbitrarily defined by the service provider).

5 is a flowchart illustrating a missed service providing method according to another exemplary embodiment of the present invention. 5 illustrates a case in which a call is sent from a calling terminal (PSTN terminal) with a mobile communication terminal having an absent service activated as a called party. 5 and 4, the method for providing an absent service according to another embodiment of the present invention is almost the same as the method for providing an absent service according to an embodiment of the present invention. However, since the originating terminal is a PSTN terminal, the gateway switching center receives a call origination signal (S510) and transmits a location information request signal (LOC_REQ) to the HLR (S512), and also responds to the location information request signal from the HLR at the gateway switching center. Receive the signal loc_req_rr and provide the missed service response message to the calling terminal (PSTN terminal). Therefore, in order to avoid duplication of description, detailed description is omitted.

In the above-described embodiments, only the mobile communication terminal and the PSTN terminal are used as examples of the calling terminal. However, it is obvious that an Internet phone or another type of terminal may be used as the calling terminal.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.

As described above, according to the present invention, a mobile communication subscriber who does not want to receive a call or is difficult to receive a call during a meeting or personal situation can block an incoming call at his or her request, but can receive an SMS or immediately check the calling party number. . That is, the subscriber can only receive the SMS while the mobile phone is turned on, and can block the call. By doing this, unlike when the mobile phone is turned off, there is an advantage of not inadvertently misunderstanding that the mobile phone is turned off by the other party, and can directly or indirectly inform the calling party that the conference attendance or unavoidable situation is caused. In addition, according to the present invention, since it is possible to receive an SMS or caller ID in case there is an important thing that you do not want to answer the call, there is an advantage that you can receive free and urgent contact from receiving the call. Therefore, it is possible to expand the range of service selection for mobile communication subscribers who do not want to receive calls or do not want to receive calls, thereby increasing convenience of service use.

On the service provider side (communication company), by using the present invention instead of turning off the mobile phone subscribers who do not want to answer or do not want to receive a call, it is possible to increase the income by the SMS call inducing effect.
