FIELD OF THE INVENTION

[0001] The present invention relates to the mobile

communication field, and more specifically to a method, an apparatus, and a system for sending a status report from a Short Message Service Center (SMSC) to a Serv-ice Provider (SP).

BACKGROUND

[0002] There are some prior arts relating to the

com-munication between a short message sender and Short Message Service Center. U.S, patent No. 6097962 re-lates to a method of handling SMS messages in a radio telecommunications network when an originating mobile station-based Short Message Entity (MS-SME) sends a SMS origination message while operating in a first Mobile Switching Center (MSC) and then moves into a second MSC before the MS-SME receives a SMS acknowledge-ment message. European patent publication No.1650990A1 is directed to a method for routing short messages using a router in a mobile telecommunications network. The method comprises: receiving a short mes-sage from a short mesmes-sage element; attempting to deliver a short message without passing through a store and forward function; and if said attempted delivery fails, di-recting said short message using a mobile originated pro-cedure to a short message service center having a store and forward function. A publication entitled "Short Mes-sage Peer to Peer Protocol Specification v3.4" by SMPP Developers Forum relates to a technical standard, in par-ticular to short message peer to peer protocol specifica-tion version 3,4.

[0003] According to statistics, in a short message

net-work architecture, about 60% of the short messages can be delivered successfully at one time, and more and more short messages need to be stored and forwarded by the SMSC. This causes that the forwarding efficiency is de-creased gradually. Based on this situation, a Short Mes-sage Service Router (SMS Router) is introduced for a first time delivery. The short messages are submitted to the SMS Router by the SP. The SMS Router delivers the short messages to cell phones. For the short messages that are not delivered successfully for the first time, which are about 30% of the submitted short messages, the SMS Router may forward these short messages to the SMSC for delivering again.

[0004] In practicing the present invention, it is

discov-ered that the short message ID received when the SP submits the short message is assigned by the SMS Rout-er. The short message ID in a status report sent to the SP, however, is assigned by the SMSC after the SMS Router forwards the submitted short message and the SMSC resends the short message. Therefore, the SP may discover that the short message ID received when the SP submits the short message does not match with

the short message ID in the received status report.

SUMMARY

[0005] A method, an apparatus, and a system for

send-ing a status report are provided in order to address the ID matching issue occurred when the SMSC sends a status report via the SMS Router.

DETAILED DESCRIPTION

[0014] Detailed description is provided for the present

invention in connection with the annexed drawings and specific embodiments. In the below embodiments, a first ID indicates an ID of a short message assigned by the SMS Router. A second ID indicates an ID of the same short message assigned by the SMSC. The SMS Router needs to send a second status report whose message ID field carries the first ID.

[0015] The relationship between the first ID and the

second ID may be conveyed to the SMS Router by in-corporating the first ID and the second ID in a first status report sent from the SMSC to the SMS Router. A mes-sage ID field in the first status report carries the second ID assigned by the SMSC. An extension filed in the first status report carries the first ID. The SMS Router may extract the first ID from the extension field in the first status report and replace the second ID in the message ID field in the first status report with the first ID to generate a second status report.

second ID may be stored in the SMS Router. When the SMS Router receives the first status report from the SM-SC, the message ID field in the first status report carries the second ID assigned by the SMSC. The SMS Router then replaces the second ID carried in the message ID field in the first status report with the first ID based on the relationship between the first ID and the second ID. The second status report is thereby obtained.

second ID may also be stored in the SMSC. When the SMSC receives a response message from the receiver, the message ID in the response message carries the

second ID. The SMSC may directly generate a second status report based on the relationship between the first ID and the second ID. In the second status report, the message ID field carries the first ID. Alternatively, a first status report may be generated first. In the first status report, the message ID field carries the second ID. Then, a second status report is generated by replacing the sec-ond ID carried in the message ID field with the first ID based on the relationship between the first ID and the second ID.

[0018] Thus, the first ID carried in the message ID field

in the second status report is assigned by the SMS Rout-er. The short message ID received when the sender in-itially submits the short message to the SMS Router is also assigned by the SMS Router. Therefore, the ID matching issue occurred when the SMSC sends the sta-tus report via the SMS Router can be addressed. Con-sequently, the sender may perform a series of operations such as charging, service accounting and service up-grade based on the second status report.

[0019] Referring to FIG. 1, a method for sending a

sta-tus report according to an embodiment of the present invention includes the following steps.

[0020] The SMS Router receives a short message

from a sender. The SMS Router assigns a first ID to the short message.

[0021] The SMS Router sends the sender an

acknowl-edgement whose message ID field carries the first ID.

[0022] In this embodiment, the sender may be the SP. [0023] S1011: The SMS Router forwards a short

mes-sage to the SMSC. The short mesmes-sage carries a first ID.

[0024] Here, an extension field may be used for

carry-ing the first ID in the short message. For example, an extension TLV field may be used for carrying the first ID.

[0025] The SMSC assigns a second ID to the short

message.

[0026] After the SMSC receives the short message

carrying the first ID, the SMSC assigns the second ID to the short message and stores the first ID. The first ID can be stored by storing the extension field as a property of the short message.

[0027] S1012: The SMSC sends a forward

acknowl-edgement to the SMS Router.

[0028] Here, a message ID field in the forward

ac-knowledgement carries the second ID. S1013: The SM-SC delivers the short message to a receiver.

[0029] In the present embodiment, the receiver may

be a mobile terminal, a stationary terminal, a multimedia terminal, etc. The mobile terminal may be a cell phone, a PDA, etc.

[0030] S1014: The receiver sends a short message

acknowledgement to the SMSC.

[0031] S1015: The SMSC sends a first status report

to the SMS Router. The first status report carries the first ID and the second ID.

[0032] Here, the message ID field in the first status

report carries the second ID assigned by the SMSC, while the extension field in the first status report carries the first

(5)

ID. The message ID field is a field for identifying the ID of the message.

[0033] S1016: The SMS Router sends a status report

[0034] S1021: The SMS Router extracts the first ID in

the extension field in the first status report and replaces the second ID in the message ID field in the first status report with the first ID to generate a second status report.

[0035] S1031: The SMS Router sends a second status

report to the sender.

[0036] S1032: The sender sends a status report

ac-knowledgement to the SMS Router.

[0037] In the present embodiment, the first status

re-port carries the relationship between the first ID and the second ID. Thus, the storage function does not need to be provided for the SMS Router which saves the storage cost for the SMS Router.

[0039] The SMS Router assigns a first ID to a short

message.

[0040] The first ID is used by the SMS Router for

iden-tifying the short message.

[0041] S2011: The SMS Router forwards the short

carry-ing the second ID in the forward acknowledgement. For example, an extension TLV field in the forward acknowl-edgement may be used for carrying the second ID.

[0046] S2013: The SMS Router stores the relationship

between the first ID and the second ID. S2021: The SM-SC delivers the short message to a receiver.

[0048] S2023: The SMSC sends a first status report

to the SMS Router.

[0049] Here, the message ID field in the first status

report carries the second ID.

[0051] S2025: The SMS Router retrieves the

relation-ship between the first ID and the second ID and replaces the second ID in the message ID field in the first status report with the first ID to generate a second status report.

[0052] S2031: The SMS Router sends the second

sta-tus report to the sender.

[0053] S2032: The sender sends a status report

ac-knowledgement to the SMS Router.

[0054] In the present embodiment, the SMS Router is

provided with a caching function for storing the relation-ship between the first ID and the second ID.

[0055] In the present embodiment, since the SMS

Router needs to store the relationship between the first ID and the second ID for a mass of short messages, in practice, the present embodiment may also include a step for deleting the relationship between the first ID and the second ID. As a result, the cache shortage problem that is caused by the case the SMS Router has to con-stantly store the relationship can be addressed.

[0056] If the SMS Router still has not received the first

status report from the SMSC when the short message times out, the relationship between the first ID and the second ID may be deleted.

[0057] Alternatively, the relationship between the first

ID and the second ID may be deleted after the SMS Rout-er replaces, based on the relationship, the first ID in the message ID field in the first status report generated by the SMSC with the second ID to generate a second status report.

[0059] The SMS Router assigns a first ID to a short

message.

[0066] S3013: The SMSC stores the relationship

be-tween the first ID and the second ID. S3021: The SMSC delivers the short message to a receiver.

[0068] S3023: The SMSC generates a first status

re-port. The message ID field in the first status report carries the second ID.

[0069] S3024: The SMSC retrieves the relationship

between the first ID and the second ID and replaces the second ID in the message ID field in the first status report with the first ID to generate a second status report.

[0070] In S3023 and S3024, the second status report

can also be generated directly based on the relationship between the first ID and the second ID after the SMSC receives the short message acknowledgement. The message ID field in the second status report carries the first ID.

port to the SMS Router.

[0073] S3031: The SMS Router sends the second

sta-tus report to the SP.

[0074] S3032: The SP sends a status report

[0075] In the present embodiment, the relationship

be-tween the first ID and the second ID is stored in the SM-SC. The SMS Router does not have to be provided with the caching function, which saves the storage cost for the SMS Router. Moreover, after the SMSC replaces the ID in the first status report, the SMS Router may trans-parently sends the second status report to the SP.

[0076] Referring to FIG. 4, an SMS Router includes:

an assigning unit 401, configured to assign a first ID to a short message sent by a sender;

a delivering unit 402, configured to incorporate the first ID in the short message and send the short mes-sage;

a replacing unit 403, configured to replace a second ID in a first status report with the first ID to generate a second status report;

a transmitting unit 404, configured to send the sec-ond status report to the sender.

[0077] In this embodiment, the SMS Router receives

the first status report generated by the SMSC, replaces the second ID in the first status report with the first ID based on the relationship between the first ID and the second ID to generate the second status report, and sends the second status report to the SP. Thus, the mes-sage ID received when the SP submits the short mesmes-sage to the SMS Router is the first ID. If the SMS Router fails to deliver the short message for the first time, the SMS Router may submit the short message to the SMSC for delivering again. Ultimately, the short message ID in the second status report returned to the SP is also the first ID. Thus, the ID matching issue occurred when the SMSC sends the status report to the SP via the SMS Router can be addressed. The SP may perform a series of op-erations such as charging, service accounting and serv-ice upgrade based on the second status report.

[0078] Referring to FIG. 5, an SMS Router includes:

an assigning unit 501, configured to assign a first ID to a short message sent by a sender;

a delivering unit 502, configured to send a short mes-sage;

a receiving unit 503, configured to receive an ac-knowledgement carrying a second ID and a first sta-tus report;

a storing unit 504, configured to store the relationship between the first ID and the second ID for the short message;

a replacing unit 505, configured to replace the sec-ond ID in the first status report with the first ID to

generate a second status report;

a transmitting unit 506, configured to send the sec-ond status report to the sender.

[0079] In the present embodiment, the storing unit for

storing the relationship between the first ID and the sec-ond ID of the short message is provided in the SMS Rout-er, which means that storage function is added to the SMS Router.

[0080] Referring to FIG. 6, an SMSC includes:

an assigning unit 601, configured to assign a second ID to a short message carrying a first ID;

a delivering unit 602, configured to send the short message to a receiver;

a storing unit 603, configured to store the relationship between the first ID and the second ID of the short message;

a reporting unit 604, configured to generate a second status report according to a response message re-turned from the receiver and the relationship. a transmitting unit 605, configured to send the sec-ond status report.

[0081] A storing unit for storing the relationship

be-tween the first ID and the second ID of the short message is provided in the SMSC. The SMSC generates the sec-ond status report based on the response message and the relationship. Thus, the SMS Router only needs to perform the transparent transmission and does not need to extent the storage function, which saves the storage cost for the SMS Router. Consequently, the issue that the ID does not match when the SMSC sends the status report to the SP via the SMS Router can be addressed. The SP may perform a series of operations such as charging, service accounting and service upgrade based on the second status report.

[0082] The second status report may be directly

gen-erated by the SMSC with the first ID as its ID, or may be generated by generating a first status report with the sec-ond ID first and then replacing the ID in the first status report with the first ID.

[0083] Referring to FIG. 7, an SMSC includes a

as-signing unit 701, a delivering unit 702, a storing unit 703, a reporting unit 704 and a transmitting unit 705. The re-porting unit 704 includes a first status subunit 7041 and a replacement subunit 7042.

[0084] The assigning unit 701 is configured to assign

a second ID to a short message carrying a first ID.

[0085] The delivering unit 702 is configured to deliver

the short message to a receiver.

[0086] The storing unit 703 is configured to store the

relationship between the first ID and the second ID for the short message.

[0087] The first status subunit 7041 is configured to

generate a first status report based on a response mes-sage returned by the receiver.

(7)

replace the second ID in the first generated status report with the first ID to generate a second status report.

[0089] The transmitting unit 705 is configured to send

the second status report.

[0090] A storing unit for storing the relationship

be-tween the first ID and the second ID for the short message is provided in the SMSC. The SMSC replaces the ID in the first status report and generates a second status re-port. Thus, the SMS Router only needs to perform the transparent transmission and does not need to extent the storage function, which saves the storage cost for the SMS Router. Consequently, the issue that the ID does not match when the SMSC sends the status report to the SP via the SMS Router can be addressed. The SP may perform a series of operations such as charging, service accounting and service upgrade based on the second status report.

[0091] A system for sending a status report is also

pro-vided according to an embodiment of the present inven-tion. The system includes:

an SMSC, configured to assign a second ID to a short message, deliver the short message to a re-ceiver and generate a first status report, wherein the message ID field in the first status report is the sec-ond ID;

an SMS Router, configured to assign a first ID to the short message, replace the second ID in the first status report with the first ID based on the relation-ship between the first ID and the second ID to gen-erate a second status report and send the second status report to a sender.

[0092] It is appreciated by those skilled in the art that

the entire or partial steps described in the above embod-iments can be implemented by associated hardware when instructed by program. The program may be stored in a computer readable storage medium. For instance, the program, when executed, performs the following steps: receiving a short message sent by the sender, assigning a first ID to the short message; incorporating the first ID in the short message and sending the short message, receiving a first status report carrying a second ID and the first ID, generating a second status report based on the first ID, and sending the second status re-port to the sender. The storage medium may be ROM/RAM, magnetic disc, optic disc, etc.

[0093] The foregoing embodiments are merely

exem-plary embodiments of the present invention. It should be noted that several modifications and variations can be made by those skilled in the art without departing from the principle of the present invention. These modifica-tions and variamodifica-tions shall be construed as falling within the scope of the present invention, as defined by the claims.
