The present invention relates to a method for notifying a short message service (SMS) to a caller according to a status of a called subscriber in a mobile communication system. In particular, the called subscriber is absent, in a call, a power-off, In the case of a page no response, the present invention relates to an SMS notification method according to the status of a called subscriber in a mobile communication system suitable for notifying the sender by SMS of a pre-stored text message.

In general, a mobile communication system is a communication system that provides a mobile communication service for a mobile object such as a person, a car, a ship, a train, an aircraft.

1 is a block diagram of an SMS notification device to a caller according to a state of a called subscriber in a conventional mobile communication system.

As shown here, a mobile station (MS) 1 that uses a wireless communication service in a mobile communication system in a state of moving or stopping at an unspecified point; It is connected to the MS 1 to perform an exchange function, and according to the state of the MS 1 of the called subscriber, the call transfer number connection and the VMS (Voice Mail System, voice information system) 6 connection, announcement broadcast and tone A mobile switching center (MSC) 4 performing a transmission function; A Home Location Register (HLR) 5 which is connected to the MSC 4 and provides status information of the MS 1 of the called subscriber; It is composed of a VMS (6) connected to the MSC (4) so that the voice recording is performed when the state of the MS (1) of the called party is impossible to call.                         

2 is a flowchart illustrating an SMS notification method to a caller according to a state of a called subscriber in a conventional mobile communication system.

As shown in the figure, when the originating MS 2 requests the outgoing call to the MSC 4, the MSC 4 requests the incoming subscriber information from the HLR 5 to receive the called subscriber status information (ST1 to ST3). )Wow; If the MSC 4 cannot connect to the destination MS 3, the MSC 4 performs an additional call service to connect to the destination MS 3 through a Call Forward (CFW) number, and connects to the VMS 6; And transmitting announcements and tones to the originating MS 2 (ST4 to ST6).

The operation of the prior art configured as described above will be described in detail with reference to the accompanying drawings.

In the prior art, when a called party is absent, busy, powered off, or page not answered, a call is provided in which a caller hears only a voice message recorded by the called party or a voice guidance service provided by a service provider. The subscriber is to listen to the voice message or the current status of the called subscriber by voice guidance or message.

Therefore, the originating MS 2 first performs a call attempt to the MSC 4 to perform a call request request (ST1).

Then, the MSC 4 requests the information of the terminating subscriber 3 of the terminating subscriber requested by the originator MS 2 to the HLR 5 (ST2).

At this time, if the call connection to the destination MS (3) is impossible (absent, busy, power-off, page non-answer, etc.), the MSC (4) performs the incoming additional service.

Thus, the MSC 4 receives the status information from the HLR 5 that the status of the called subscriber is absent, busy, powered off, page not answered, and the like.

The MSC 4 then connects the call transfer number to the destination MS 3 (ST4).

The MSC 4 connects to the VMS 6 to enable voice recording at the originating MS 2 (ST5).

In addition, the MSC 4 transmits the announcement broadcast and the tone from the originating MS 2 (ST6).

In this case, when the calling subscriber is not immediately connected to the called subscriber, the calling subscriber connects to the announcement broadcasting device of the MSC 4 according to the status of the called subscriber and listens to the announcement provided by the operator, or listens to the VMS 6 of the called subscriber. By connecting to the voice message recorded by the called party, the current status of the called party can be determined and the voice message can be left to the called party.

However, this conventional technology has the following problems.

That is, in the related art, the problem in providing the voice guidance service when the called subscriber of the mobile communication system is missed, busy, power off, page not answered, etc. is as follows.

First, when an incoming subscriber incorrectly hears, forgets, or wants to listen to a recorded voice message, there is a hassle of having to call the recipient again to check the voice message.

Second, there is a problem in that the recording state of the voice message left by the called subscriber is poor, or the calling subscriber cannot correctly listen to the voice message due to a temporary instability of the mobile communication network.

Third, there is a limit in the message expression because the message should be left only in the form of voice.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is a text message stored in advance by the called party according to the case where the called subscriber is absent, busy, power off, page not answered, The present invention provides a method for notifying an SMS to a caller according to a status of a called subscriber in a mobile communication system capable of notifying the caller by SMS.

As shown therein, the MS 10 uses a wireless communication service in a mobile communication system while moving or stopping at an unspecified point; The MSC 20 is connected to the MS 10 to perform an exchange function and performs a call transfer number connection or VMS 40 connection or announcement broadcasting and tone transmission functions according to the state of the MS 10 of the called subscriber. Wow; An HLR 30 connected to the MSC 20 to provide status information of the MS 10 of a called subscriber; A VMS (40) connected to the MSC (20) so that voice recording is performed when the state of the MS (10) of the called subscriber cannot be connected; When the MS 10 of the called subscriber receives a subscriber text message transmission request from the HLR 30 when the call connection is unavailable, the MS 10 sends a text message to the MS 10 of the calling subscriber, and the MS of the called subscriber ( And a Short Message Service Center (SMSC) 50 for storing text messages from 10).

4 is a flowchart illustrating an SMS notification method for a caller according to a state of a called subscriber in a mobile communication system according to the present invention.

As shown in FIG. 1, when the originating MS 11 requests an outgoing call from the MSC 20, the MSC 20 requests the called subscriber information from the MSC 20 to the HLR 30 to receive the called subscriber status information (ST11). ~ ST13); If the call connection to the terminating MS 12 is not possible, the MSC 20 transmits an announcement and a tone from the MSC 20 to the originating MS 11, and connects the VMS 40 and the originating MS 11 to generate a voice message. A second step ST14 to ST16 for recording; If the call connection to the destination MS 12 is not possible, a third request is made to send a text message from the SMSC 50 to the originating MS 11 by requesting transmission of a subscriber text message from the HLR 30 to the SMSC 50. Step ST17 and ST18; A fourth step (ST19) of registering the additional service from the destination MS (12) to the HLR (30) after the third step; A fifth step (ST20) of recording a voice message from the destination MS (12) to the VMS (40) after the third step; And after the third step, a sixth step ST21 for storing a text message from the destination MS 12 to the SMSC 50.

The operation of the SMS notification method to the caller according to the state of the called subscriber in the mobile communication system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the present invention is intended to notify the caller by SMS of a text message stored in advance by the called party according to the case where the called subscriber is absent, busy, power off, and no page response.

Therefore, in the case where the called subscriber of the mobile communication system is absent, busy, power off, page not answered, etc., the receiver can supplement the problem of the voice guidance service and leave the message only in the conventional voice message. Save the text message that you want to leave in SMSC (50), and according to the status of the called subscriber to the SMS subscriber to send a text message stored by the called subscriber to the voice guidance service and text message at the same time with the voice guidance service of the called party And text messaging services.

Thus, the MS 10 uses the wireless communication service in the mobile communication system while moving or stopping at an unspecified point.

The MS 10 includes an originating MS 11 of an originating subscriber and a terminating MS 12 of a called subscriber.

Thus, the originating MS 11 performs the originating call request to the MSC 20. In addition, the originating MS 11 receives the announcement and tone transmission from the MSC 20 when the call connection is impossible at the destination MS 12. In addition, the SMSC 50 receives a text message. Therefore, the originating MS 11 can receive not only the voice message guide service but also the text message guide service in the absence of the destination MS 12.

In addition, the destination MS 12 may be connected to the HLR 30 to register additional services. In addition, the voice message may be recorded by the VMS 40, and the text message may be stored by the SMSC 50. In this way, the voice message and the text message stored in the VMS 40 and the SMSC 50 can be delivered to the originating MS 11 when the terminating MS 12 cannot make a call.

The exchange 20 is connected to the MS 10 to perform an exchange function, and according to the state of the MS 10 of the called party, the call transfer number connection or the VMS 40 connection or announcement broadcast transmission and tone transmission functions. do.

In addition, the HLR 30 is connected to the MSC 20 to provide status information of the MS 10 of the called subscriber. Thus, when the HLR 30 wants to register the additional service in the destination MS 12, it registers it. Such supplementary services include a service for providing a guide service as a text message as well as a voice message when the user is absent or busy.

In addition, the VMS 40 is connected to the MSC 20 so that the voice recording is performed when the state of the MS 10 of the called subscriber is not connectable. Therefore, the VMS 40 requests the outgoing MS 11 to send the subscriber voice message when the called MS 12 cannot connect to the call, thereby recording the voice message transmitted from the originating MS 11.

In addition, the SMSC 50 receives a subscriber text message transmission request from the HLR 30 when the MS 10 of the called subscriber is in an unreachable state, and sends a text message to the MS 10 of the calling subscriber. Save the text message from the MS 10.

Referring to the operation of the present invention in more detail as follows.

First, the subscriber registers and stores the subscriber's desired text message in his or her SMSC 50 according to the status of missed, busy, power off, no page response. Therefore, when the calling subscriber attempts to connect the call to the called subscriber, when the call cannot be connected, the voice guidance service connects to the calling subscriber and hears the text message left by the called party.

So, first, the originating MS 11 is connected to the MSC 20 to perform an outgoing call request (ST11).

The MSC 20 then requests the called subscriber information to the HLR 30 to the HLR 30 (ST12).

The HLR 30 then responds to the called subscriber information to the MSC 20. At this time, the HLR 30 informs the MSC 20 of a status such as missed or busy or power off or no page response when the incoming MS 12 cannot connect to the call (ST13).

The MSC 20 then performs announcement and tone transmission to the originating MS 11 (ST14).

The VMS 40 also requests the subscriber MS 11 to send a subscriber voice message (ST15).

Then, the originating MS 11 transmits the voice message to the VMS 40 so that the VMS 40 can record the voice message transmitted from the originating MS 11 and deliver it to the destination MS 12 later (ST16).

If the call connection to the destination MS 12 is not possible, the subscriber station sends a text message to the SMSC 50 from the HLR 30 (ST17).

Then, the SMSC 50 receives a text message containing the message that the call connection from the SMS MS 50 to the destination MS 12 is impossible (ST18).

Then you can register additional services and save text messages.

Therefore, the destination MS 12 is connected to the HLR 30 to register the additional service (ST19). These additional services include not only voice messages but also services that can guide services by text message.

In addition, it is possible to record a voice message from the destination MS 12 to the VMS 40 (ST20).

In addition, the recipient MS 12 allows the SMSC 50 to store the text message (ST21).

As described above, according to the present invention, the called party notifies the sender of the text message stored in advance by the called party according to the absence, busy, power off, and no page response.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, in the mobile communication system according to the present invention, the SMS notification method to the caller according to the status of the called party is stored in advance by the called party according to the case where the called party is absent, busy, power off, and no page response. It is effective to notify sender by SMS of one text message.

In addition, the present invention is a zoom to notify the caller by SMS in accordance with the status of the incoming subscriber (busy, busy, power-off, page non-response, etc.) in the mobile communication system, a text message to escape the conventional voice message type, By adding a type of guidance service, if the user forgets the voice announcement message recorded by the called party or wants to listen again, the caller can be called again to check the voice message left by the called party.

In addition, the present invention compensates for problems such as when the calling subscriber does not correctly listen to the voice message left by the called party due to poor recording state of the voice message or temporary instability of the mobile communication network, or the limitation of expression in the form of voice message. It is effective to provide a useful service to the.
