Abstract

A short message transmission system in a mobile communication network and a service method thereof are provided to prevent a short message, of which the transmission time is important, from being treated as a spam message by deleting a short message, in case of expiring the transmission time, and canceling the transmission of the short message. A short message transmission system in a mobile communication network comprises an originating mobile terminal(10), an HLR(Home Location Register)(60), and an SMSC(Short Message Service Center)(50). The originating mobile terminal(10) sets up an expiration time for short message deletion, and makes out a short message. The HLR(60) confirms the location of a terminating mobile terminal(100) to which the short message will be delivered. The SMSC(50) receives the short message from an MSC(Mobile Switching Center), and deletes the short message if the HLR(60) fails in confirming the location of the terminating mobile terminal(100) within the expiration time of the short message.

Information transmitted from the mobile switching center (MSC) 40, 70 via the (30, 80), the information transmitted from the mobile switching center (MSC) 40, 70 is the base station (BTS) 20, 90 and the base station controller (BSC) (30, 80) is transmitted to the mobile terminal (10, 100).

The originating mobile terminal 10 of the present invention sets the expiration time when the subscriber creates the short message, and transmits the short message having the set expiration time to the mobile switching center (MSC) 40 through the base station (BTS) 20. do.

The base station (BTS) 20, 90 connects the mobile terminal 10, 100 to the base station controller (BSC) 30, 80, and communicates wirelessly with the mobile terminal 10, 100, and the base station controller (BSC) ( 30, 80) to perform a wired or wireless conversion function to perform a wired communication.

The base station controller (BSC) 30, 80 connects the base station (BTS) 20, 90 to the mobile switching center (MSC) 40, 70 to coordinate the connection between the base station (BTS) 20, 90, It supports the base station (BTS) 20, 90, and serves as a signal processing function for communication between the base station (BTS) (20, 90) and the mobile switching center (MSC) (40, 70).

Mobile switching center (MSC) (40, 70) is connected to the call of the mobile terminal (10, 100), connected to the base station controller (BSC) (30, 80) to establish and release the call of the mobile terminal (10, 100) Etc., performs various functions related to call processing and supplementary services, and performs interworking with other networks.

The short message service center (SMSC) 50 manages the short message parameter setting, the short message transmission to the mobile switching center (MSC) 40, 70, and the short message transmitted for a predetermined time. Then, the short message transmitted through the outgoing mobile terminal 10 or another network is transferred to the corresponding mobile switching center (MSC) 70 of the incoming mobile terminal 100.

The short message service center (SMSC) 50 of the present invention sends a short message having a set expiration time delivered from the mobile switching center (MSC) 40 of the calling mobile terminal 10 to the mobile switching center of the terminating mobile terminal 100. (MSC) 70, but if the incoming mobile terminal 100 is turned off, or when located in the shadow area that can not call, the short message is stored and managed during the expiration time of the short message. If the expiration time of the short message elapses, the short message is automatically deleted.

The home location register (HLR) 60 is a database that stores permanent information of the mobile terminals 10 and 100, subscribers, location information, and additional service information.

The short message transmission system of the mobile communication network according to the present invention configured as described above sets the expiration time together with the short message when the short message is created in the originating mobile terminal 10, and the short message having the set expiration time is the incoming mobile terminal 100. ) Together with the MIN number to the short message service center (SMSC) 50 via the base station (BTS) 20 and the mobile switching center (MSC) 40.

The short message service center (SMSC) 50 receives the mobile terminal 100 at the home location register (HLR) as the terminating mobile terminal 100 is turned off during the expiration time in the short message or is located in a shadowed area where the call is impossible. ) If the location is not registered, the short message is saved and managed.

If the expiration time of the short message has elapsed, the short message service center (SMSC) 50 deletes the short message and registers the location of the incoming mobile terminal 100 with the home location register (HLR) within the short message expiration time. In this case, the short message is transmitted to the mobile switching center (MSC) 70 where the called mobile terminal 100 is located.

Therefore, the present invention deletes the short message when the incoming mobile terminal 100 is turned off or when the transmission time of the short message has passed the set expiration time in a shaded area where the call is impossible, thereby canceling the transmission of the message. Important short messages (e.g. taxi calls, stock information, etc.) can be prevented from being treated as spam messages after the transmission time has elapsed.

2 is a flowchart sequentially illustrating a service method of a short message transmission system of a mobile communication network according to the present invention.

1 and 2, the short message transmission system of the mobile communication network according to the present invention proceeds as follows.

First, a short message is created in the outgoing mobile terminal (MS1) 10, the expiration time (for example, 3 minutes) is set together when the short message is created, and the message is transmitted after the incoming MIN number is input. The short message is transmitted to the mobile switching center (MSC) 40 through the base station (BTS) 20 and the base station controller (BSC) 30 in the form of a data burst message [Ack Req = 1]. Ack Order [Ack Req = 1], MS Ack Order [Ack Req = 0]). (S10) That is, referring to FIG. 3, the present invention uses Korean, English, or special characters through a keypad of an originating mobile terminal. When the short message is created 12 by inputting the expiration time, the expiration time (for example, 3 minutes) is set and inputted together.

The mobile switching center (MSC) 40 forwards the short message (SMDDP [MIN, OOA]) with an expiration time to the short message service center (SMSC) 50, stores it, and stores the short message service center (SMSC) 50 ) Transmits a message reception response (smdpp []) to the MSC 40 (S20).

The mobile switching center (MSC) 40 responds to the receipt of the message in the form of a Data Burst Message [Ack Req = 1] (BS Ack Order [Ack Req = 1], MS Ack Order [Ack Req = 0]). Is transmitted to the originating mobile terminal (MS1) 10 through the base station (BTS) 20, the base station controller (BSC) 30. (S30)

The short message service center (SMSC) 50 requests the home location register (HLR) 60 to confirm the location of the terminating mobile terminal (MS2) 100 (SMSREQ [MIN]).

The short message service center (SMSC) 50 transmits the short message to the called party mobile switching center (MSC) 70 located at the home location register (HLR) 60 when the expiration time of the short message has not elapsed. SMDDP [MIN, ESN, OOA]) (S50).

The destination mobile switching center (MSC) 70 converts the short message into a data burst message form (Data Burst Message [Burst Type = 3, Ack Req = 1]) when the short message is transmitted within the expiration time of the short message. (BSC) 80 and base station (BTS) 90 are transmitted to the corresponding destination mobile terminal (MS2) 100 (MS Ack Order [Ack Req = 1], BS Ack Order [Ack Req = 0]). (S60)

However, when the terminating mobile terminal (MS2) 100 is turned off in the home location register (HLR) 60, or when the positioning of the terminating mobile terminal (MS2) 100 is not made in a shaded area where the call is impossible, The home location register (HLR) 60 transmits the location resolution impossible to the short message service center (SMSC) 50 (smsreq [ESN, SMSADDRESS]). (S70)

And when the short message transmission from the destination mobile switching center (MSC) 70 to the destination mobile terminal (MS2) 100 has passed the expiration time set in the message, the short message service center (SMSC) 50 is notified of this (smdpp [ (S80)

The short message service center (SMSC) 50 deletes the short message when the expiration time of the short message has elapsed. (S90)

The short message service center (SMSC) 50 informs the destination mobile switching center (MSC) 70 that the short message whose expiration time has elapsed has been deleted (S100).

The destination mobile switching center (MSC) 70 transmits the deletion information of the short message whose expiration time has elapsed to the base station controller (BSC) 80 and the base station (BTS) in the form of a data burst message [Ack Req = 1]. (90) (BS Ack Order [Ack Req = 1], MS Ack Order [Ack Req = 0]) to the corresponding destination mobile terminal (MS2) 100 through (90).

Therefore, the present invention sets an expiration time together with a short message when the short message is created in the outgoing mobile terminal 10, and the short message having the set expiration time includes the MIN number of the destination mobile terminal 100 together with the base station (BTS) ( 20), to the short message service center (SMSC) 50 through the mobile switching center (MSC) 40, the destination mobile terminal 100 is turned off or in a shaded area where the call is turned off during the expiration time in the short message; If the location confirmation of the terminating mobile terminal 100 is not performed in the home location register (HLR), the short message service center (SMSC) 50 is stored and managed when the expiration time of the short message has elapsed. Deletes the short message and notifies the called mobile terminal 100 of this.

In the preferred embodiment of the present invention, the outgoing mobile communication terminal 10 has been described with an example of transmitting a short message having an expiration period. However, as another embodiment, the short message is received by the short message service center 50. If the location confirmation of the terminating mobile communication terminal 100 is not performed in the home location register 60 during the set message expiration time, the short message is automatically deleted and then the terminating mobile communication terminal 100 is notified of the deletion of the short message. have.

Meanwhile, in the embodiment of the present invention, the subject for transmitting the short message is limited to the mobile communication terminal. However, in another embodiment, the content providing server, for example, stock information, useful information for life, coupon information, etc. You can also send a short message from the content providing server provided by. In this case, the short message is transmitted to the short message service server (not shown) interworking with the content providing server and then provided to the short message service center 50, and the short message service center 50 is provided from the short message service server. When the expiration time is set in the short message, if the location is not confirmed after checking the location of the incoming mobile communication terminal 100 in the home location register 60 during the expiration time, the short message is deleted or the expiration time is set in the short message. If not, the short message may be deleted if the location is not confirmed after checking the location of the incoming mobile communication terminal 100 in the home location register 60 for a preset message expiration time.

As described above, the present invention deletes the short message by canceling the short message when the mobile terminal is turned off or when the transmission time of the short message has passed the set expiration time in the shadow area where the call is not available. Important short messages (eg taxi calls, stock information, etc.) can be prevented from being delayed and treated as spam messages.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
