The present invention relates to a short message service, and more particularly, a short message not arrived notification for informing the calling subscriber in the form of a short message of an unarrival status of the short message transmitted from the calling mobile terminal and the final processing result of the message. A service method and apparatus therefor.

Short Message Service (SMS) is a service that delivers various useful services and life information through text through the LCD screen of a mobile communication terminal. Short message service is provided by a mobile communication terminal subscriber to send and receive a short message in a text form in connection with a base station, an exchange, a home location register, and a short message center in a mobile communication system. The short message may be made between mobile communication terminals, or may be made between an information server of an operator providing various information and a personal mobile communication terminal.

The mobile communication terminal or information provider transmits the short message to be sent and the number of the called party's mobile communication terminal. The sent short message and called party are stored in the message queue of the short message center through the base station and the switching center. At this time, a message indicating whether the short message is normally transmitted to the short message center is transmitted to the calling party.

The short message center transmits the short message to the corresponding mobile communication terminal for a predetermined time according to the called number received together with the short message until the reception response message is received. The short message center deletes the short message stored in the message queue and terminates the short message transmission when the reception response message is not received or the reception response message is not received for a predetermined time.

As described above, since the short message is sent and the incoming call is divided, the calling party cannot confirm whether the short message is transmitted.

Therefore, in the short message service according to the prior art, there is a problem that the calling subscriber does not know the non-arrival status of the short message transmitted from the calling mobile terminal and the final processing result of the message.

Accordingly, the present invention has been made to solve the above-mentioned problems, the present invention, the present invention informs the SMS sending subscriber of the short message transmission result in the mobile communication system by the sender is a short message sent by the sender through his SMS short message service Short message arrival notification service method that can easily know whether the message is properly transmitted to the other party's wireless terminal, and that the calling subscriber can check whether the SMS arrives or retransmits to the mobile terminal of the other party without a specific procedure, and its In providing a device.

Short message not arrived notification service method according to a first aspect of the present invention for achieving the above object, in a mobile communication network, when receiving a request for the transmission of a text message from the terminal subscribed to the SMS not arrived notification service in the MSC, Requesting, by an MSC, an SMS notifying the short message of arrival of the short message; When the SMSC receives the non-arrival notification processing request for the short message from the MSC, the SMSC determines whether the text message is a non-arrival notification processing target based on the number of the called terminal including the text message and the number corresponding to the specific code. Judging by; If it is determined that the text message is a non-arrival notification object, the SMSC notifies the SMS originating subscriber of the transmission result according to the success, retransmission or failure of the text message based on a preset reference time. Characterized in that it comprises a.

Short message not arrived notification service device according to a second aspect of the present invention for achieving the above object, in the mobile communication network, when the terminal of the non-arrival notified service subscriber registers the location not registered to the corresponding switching center (MSC) HLR giving information; An MSC for requesting the SMSC to process the text message when receiving a request to send a text message from a terminal subscribed to an SMS not-arrival notification service; And an SMSC analyzing the specific code of the text message request information to determine whether the notification message has not been arrived, and notifying the SMS calling subscriber of the transmission result according to the success, retransmission, or failure of the text message based on a preset reference time. Characterized in that.

Therefore, according to the present invention, by sending a short message transmission result to the SMS calling subscriber in the mobile communication system, the sender can easily know whether the short message transmitted by the sender through the SMS short message service is properly transmitted to the other party's wireless terminal. In addition, the originating subscriber can check whether the SMS arrives and retransmits to the mobile terminal to which the other party is called, without a specific procedure.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

A diagram illustrating a call processing procedure when a call is successful before a predetermined time has elapsed after a subscriber sends a short message to a call destination mobile terminal in its own network using its own terminal.

First, the calling mobile terminal 10 transmits a short message to be transmitted to the BS 11 according to the calling subscriber input. That is, the short message is transmitted in the same manner as the conventional short message transmission.

The short message is then sent to the BS 11 and the originating mobile switching center (

: Is transmitted to the SMSC 15 through the Mobile Switching Center (12, 13). At this time, the calling mobile switching center (

12 transmits an SMS transmission request message (SMDPP) to the SMSC 15 (S201), and waits until a response message (smdpp) based on a short message transmission result is received from the SMSC 15 ( S202). At this time, the calling mobile switching center (

12 transmits an OSFI parameter value, such as "OSFI = SMS_Fail_Noti", to the SMSC 15 in the SMDPP operation to request an SMS transmission, and the SMSC 15 checks the OSFI parameter value to determine the text message. Confirm the transfer request. At this time, the OSFI parameter is transmitted to the mobile switching center based on the service information on the originating subscriber that the HLR 14 has.

Subsequently, the SMSC 15 checks whether the corresponding message is an SMS non-arrival notification service processing target message according to the present invention.

Abbreviated as) for a preset reference time (S203).

In addition, the reference time means a sufficient time for the transmission result message for the transmitted short message to be received, and the following operation is performed during the reference time.

In the checking process, the SMS non-arrival notification service is not provided in the following cases.

1) International SMS

2) Event SMS (It should be implemented to reflect the event SMS event number change)

3) Number to be routed to SMS server

4) In case of XMS message (TID = DBM)

5) In case of Long SMS and Total Segment ≠ Current Segment (that is, Long SMS handles the arrival notification service only for the last message).

Thereafter, the SMSC 15 transmits a subscriber information request message (SMS_Request) requesting information on the counterpart terminal subscriber to the HLR 14 (S204), and the counterpart terminal subscriber sends a short message from the HLR 14. A subscriber information response message (sms_request) indicating that it can be received is received (S205).

Thereafter, the SMSC 15 transmits the called party's mobile switching center (

In step S407, the short message transmission result message smdpp including the reason why the short message cannot be transmitted is received. At this time, the called party's mobile switching center (

The parameter value included in) 13 in the short message transmission result message smdpp is "SMS_CauseCode".

Then, the SMSC 15, if the short message transmission result message (smdpp) is a message that manages to immediately fail processing without attempting to resend the timer (

) And the short message is deleted (S408).

Thereafter, the SMSC 15 generates a message Noti-SMS1 indicating that the final failure is processed immediately during the incoming process without proceeding with the retransmission procedure and transmits the message Noti-SMS1 to the calling mobile terminal 10 (S409). In this case, the message (Noti-SMS1) is a message generated by the network and transmitted to the SMS originating subscriber in order to inform the final failure result of the incoming process without proceeding with the retransmission procedure for the non-arrival notification service processing target message according to the present invention. .

FIG. 5 illustrates a call processing procedure when an SMS originating subscriber sends a short message to an incoming target mobile terminal in its own network using his terminal, and attempts to resend the call without success when the reference time elapses. The figure shown.

Since the operations of steps S501 to S503 are the same as those of the steps S201 to S203 of FIG. 2 and the steps S504 to S507 of FIG. 4, they are omitted here.

First, the SMSC 15 attempts to retransmit the message according to a predetermined procedure, which means that the incoming call does not succeed during the reference time. At this time, the SMSC (15) is the timer (

) Generates a message (Noti-SMS2) indicating that the incoming call to the corresponding message was not successful until the reference time, and transmits the message to the calling mobile terminal 10 (S508). At this time, the message (Noti-SMS2) is generated in the network to inform the result of the unsuccessful call until the reference time after the transmission process proceeds to the re-transmission procedure, and the incoming call processing target message according to the present invention This message is sent to subscribers who send SMS. It can be expressed as "Currently the message cannot be delivered. (XXX Calling Number) (XX / XX XX: XX Time)".

Thereafter, the SMSC 15 repeats the message retransmission process of step S508 (S509).

Thereafter, the SMSC 15 generates a predetermined message (Noti-SMS3, Noti-SMS4) according to whether or not the incoming message is successfully received at the time when the corresponding message is finally deleted, and then the calling mobile terminal 10 (S510). Here, the predetermined message (Noti-SMS3) is a message indicating that the incoming call to the destination terminal is successful during the retransmission process. It can be expressed as "Successful message transmission. (XXX Caller ID) (XX / XX XX: XX time)", and the predetermined message (Noti-SMS4) means when the message is deleted due to expiration of the retransmission process. Message, and may be expressed as "Failure to send next message due to customer's circumstances. (XXX Caller ID) (XX / XX / XX: XX time)."

Since operations of steps S601 to S603 are the same as those of steps S201 to S203 in FIG. 2, they are omitted here.

First, the SMSC 15 transmits a subscriber information request message (SMS_Request) requesting information on the subscriber of the other party to the HLR 14 (S604). When the called terminal is powered off, the HLR 14 In step S605, a subscriber information response message (sms_request) indicating the status is received. At this time, the HLR 14 records "SMSADR = Postponed" in the subscriber information response message sms_request and transmits it to the SMSC 15.

The SMSC 15 attempts to retransmit the message according to a predetermined procedure.

If the incoming call to the corresponding message is not successful until the reference time is reached, the message Noti-SMS2 is generated and transmitted to the calling mobile terminal 10 (S606).

Then, when the incoming target terminal is in the power-on state (location registration) (S607), the progress message incoming procedure by the general power-on is performed (S608 ~ S610).

Thereafter, the SMSC 15 deletes the message after the successful reception of the message (S611), and finally, the message (Noti-SMS3) according to whether or not the incoming message is successfully received at the destination terminal when the message is deleted. Generate and transmit to the calling mobile terminal 10 (S612).

If the message is deleted from the SMSC 15 because the destination terminal does not become a power-on state within the retransmission setting reference time in steps S606 to S607, the message (Noti-SMS4) is deleted. ) Is generated and transmitted to the calling mobile terminal 10.

In case of receiving the subscriber information response message (sms_request) indicating the status from the HLR (14) (S805). At this time, the HLR 14 records "SMSADR = Ported_Out" in the subscriber information response message sms_request and transmits it to the SMSC 15.

Thereafter, the SMSC 15 terminates driving of the timer, which has been driven in step S803 (S806).

Thereafter, the SMSC 15 stores the esm_class parameter in the SMPP protocol deliver_sm to indicate that the SMS is not an incoming call to the subscriber of the number, and that the message has not been received. (S807).

Subsequently, the SMS server 17 performs a process of receiving the other network for the message received from the SMSC 15 and an SMS non-arrival notification service for the calling subscriber (S808).

Thereafter, the SMS server 17 generates a predetermined message (Noti-SMS) for notifying the non-arrival and final status of the message, and transmits the message to the subscriber who sent the SMS (S809). This process is the same as the procedure of transmitting a general message.

Since operations of steps S901 to S904 are the same as those of steps S701 to S704 of FIG. 7, the description thereof will be omitted here.

Subsequently, the SMS server 17 performs another incoming call processing for the message received from the SMSC 15 and an SMS non-arrival notification service for the calling subscriber (S905). In this case, when the target subscriber in the third party service network turns out to be the subscriber who has been ported to the same service network (own service network) as the SMS originating subscriber and returns the call, it queries the number portability solution (NPDB) and returns to the company's service network again. Proceed with the procedure.

Thereafter, the SMS server 17 transmits the message to the SMSC 15 (S906). At this time, the SMS server 17 is an incoming call according to the number portability subscriber whose number is transferred from the service network of the other party to the own network, and at the same time, the SMS server 17 indicates that the incoming message is a message to be processed by the SMS non-arrival notification service. The esm_class parameter is stored (S807).

Thereafter, the SMS server 17 drives the timer for the message received from the SMSC 15, and performs the incoming processing in the own network and the SMS non-arrival notification service for the calling subscriber (S908).

The HLR according to the present invention is given a function of adding an SMS_Fail_Noti according to an additional service field for each subscriber and enabling the subscriber to activate / deactivate (act / deact) using a specific code.

The above-described expression method of the predetermined messages (Noti-SMS1 to Noti-SMS4) indicating the reception success and failure described above is just one example and may be expressed in various forms.

As described above, in the present invention, the SMSC waits for a predetermined time without ending until the short message transmission result is received from the SMSC, and when the short message transmission result is received, the SMSC transmits the short message by notifying the subscriber of the SMS transmission. Since the result is not informed, the SMS outgoing subscription can solve the problem of not knowing the result of the short message transmission.

The present invention is only one embodiment, and many variations and modifications of the components of the present invention are possible without departing from the gist of the present invention, and are not limited to the embodiments according to the present invention.
