FIELD OF THE INVENTION
This application relates to the communication technology and in particular, to a method
and apparatus for handling delivery status report.
BACKGROUND
Current in GSM (Global System of Mobile communication) or SMPP (Short Message Peer
to Peer) network, delivery status report is very important information for the sender to know
the delivery status of the short message specifically when sending urgent SMS. Generally
SMSC sends status report in one language; it may be in Chinese or English etc.
But sometimes it is difficult for the sender to understand the message content to know the status because of the language problem. For example a sender who understands English, but gets a delivery status report in Chinese. He may not understand the delivery status report content if it was delivered successfully.
One solution can be that SMSC maintains language information for each user. However, the applicant found that: this needs huge resource and there will be impact on performance. Updating user information every time is very difficult task.
Also this will not provide flexibility to use the same mobile handset by multiple users of different language. For example, if a Chinese user wants to use the handset used by an English user, then he needs to provision again for Chinese language in the SMS (Short Message Service) system. Such that provisioning every time is not convenient.

The preferred embodiments of the present invention are described as follows in
reference to the drawings.
Embodiment 1
This embodiment of the present invention provides a method of handling delivery status report, applied in a SMSC.
Figure 1 is a flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention. As shown in Figure 1, the method includes:
Step 101, the SMSC receives a short message, wherein the short message includes language information for indicating language of the delivery status report;
Step 102, the SMSC handles the short message;
Step 103, the SMSC generates the delivery status report with the language indicated by the language information according to the result of handling the short message;
Step 104, the SMSC sends the delivery status report.
In this embodiment, the short message may include the language information, the language information may be added into the short message by the UE which sends the short message.
In this embodiment, the SMSC will handle the short message and generate the delivery status report according to the result of handling the short message. How to handle the short message, please refer to the existing technology.
In this embodiment, the SMSC may generate the message content of the delivery status report according to the language information when the SMSC generates the delivery status report. Or the the SMSC may translate the content of the delivery status report according to the

language information after the SMSC generated the delivery status report. However, it is not limited thereto.
In this embodiment, the SMSC sends the delivery status report in the requested language; such that the sender requests delivery status report at specific language by using language information included in the short message, and UE is not need to send a special message to set the language information into the SMS system in advance.
In this embodiment, the sender may inform the language information in addition optional field, and the short message may be submitted by using SMS-Submit or SMPP-Submit SM or SMPP-Data SM. However it is not limited thereto, this can be extended to other protocols of SMS standard, and particular implement way may be determined as actually required.
In this implement way, once the SMSC receives this language information, it will generate the message content of delivery status report with the language indicated by the language information.
So if the sender sends short message with language as English, then the SMSC will send message content in delivery status report in English. If the sender sends short message with language information as Chinese, then the SMSC will send message content in delivery status report in Chinese.
So, the sender will receive the delivery status report in correct language. He will be able to take corrective action in case the status in deliver reports says FAILED. If he does not understand the message content in the delivery status report, he will not be able to take any action.
In an implement way, the short message may be sent by a ESME (External Short Message Entity) in SMPP (Short Message Peer to Peer); and the short message is submitted by using submit_sm or data_sm in the SMPP protocol, and the language information is indicated by a TLV (Tag Length Value) of the submit_sm or data_sm in the SMPP protocol. The delivery status report is deliver_sm in SMPP, and the message content of the delivery status report is carried in the "short message "field o/deliver_sm.
Wherein the TLV may be named as Language_For_Delivery_Receipt, and the Language_For_Delivery_Receipt includes a value to indicate the language.
Table 1 has shown the Language_For_Delivery_Receipt as an example. In SMPP, following optional TLV will be added. The Language_For_ Delivery_Receipt parameter may be a required parameter for the ESME to request delivery receipt in particular language.

Figure 2 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention. As shown in Figure 2, the method includes:
Step 201, the SMSC receives a short message, wherein the short message includes language information for indicating language of the delivery status report;
In this implement way, a Language_For_ Delivery_Receipt is added to indicate the language information. That is to say, an ESME may submit message using submitsm or data_sm with optional TLV (Language_For_Delivery_Receipt) to request delivery receipt of SMS at specific language.
Step 202, the SMSC extracts the Language_For_ Delivery_Receipt from the short message;
Step 203, the SMSC records the Language_For_ Delivery_Receipt against the identifier of the short message.
Step 204, the SMSC handles the short message;
Step 205, the SMSC generates the delivery status report with the language indicated by the language information according to the result of handling the short message;
In implement, the SMSC may first generate a delivery status report according to the existing technology. And then translate the message content of the delivery status report based on the Language_For_Delivery_ Receipt. Then, the SMSC may insert translated message content into the delivery status report.
Or, when the SMSC generates the delivery status report, the message content of the delivery status report may be generated with the language indicated by the Language_For_Delivery_ Receipt directly.
Step 206, the SMSC sends the delivery status report with the language indicated by the language information.
In this implement way, the SMSC may extract the Language_For_ DeliveryReceipt and record the language information carried in the Language_For_ Delivery_Receipt against the identifier of the short message. The message content of the delivery status report is in English or Chinese or any other language depending upon Language_For_Delivery_Receipt TLV.
Figure 3 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention; Figure 4 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention.
As shown in Figure 3, the value of the Language_For_Delivery_Receipt is "0", this means the language is English; so that if the short message was expired in SMSC, the message

content carried in "shortjnessage" field of deliver_sm is "Expired".
In this case, English user requests for delivery status report in English language. The message was expired in SMSC. SMSC sends short jnessage content in delivery status report as "EXPIRED". So he knows the SMS has not been delivered successfully; now he can try sending again. If he received in Chinese, he would not have understood that the SMS was expired.
As shown in Figure 4, the value of the Language_ For_Delivery_Receipt is "1", this means the language is Chinese; so that if the short message was expired in SMSC, the message content carried in"short_message" field of deliver_sm is "□D".
In this case, Similarly, Chinese user requests for delivery status report in Chinese language. The message was expired in SMSC. SMSC sends short jnessage content in delivery status report as "□ □ ". So he knows the SMS has not been delivered successfully; now he can try sending again. If he received in English, he would not have understood that the SMS was expired.
In another implement way, the short message may be sent by a MS (Mobile Station) in GSM (Global System of Mobile communication); and the language information is indicated by a parameter, the short message is submitted by using SMS-SUBMIT in the GSM protocol, such as GSM 0340 protocol. The delivery status report is SMS-STATUS- REPORT in GSM, and the message content of the delivery status report is carried in the "TP-User-Data " field of SMS-STATUS- REPORT.
Wherein the parameter may be named as TP_LANGUAGE, and the TP_LANGUAGE is used to indicate the language.
Table 2 has shown the TP_LANGUAGE as an example. In GSM 0340 standard, following optional new field as below will be added.
Figure 5 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention. As shown in Figure 5, the method includes:
Step 501, the SMSC receives a short message, wherein the short message includes

language information for indicating language of the delivery status report;
In this implement way, a TPJLANGUAGE is added to indicate the language information. That is to say, a MS (Mobile station) may submit message using SMS-SUBMIT with optional parameter (e.g. TP-LANGUAGE) to request delivery receipt of SMS at specific language.
Step 502, the SMSC extracts the TP_LANGUAGE from the short message;
Step 503, the SMSC records the TP_LANGUAGE against the identifier of the short message.
Step 504, the SMSC handles the short message;
Step 505, the SMSC generates the delivery status report with the language indicated by the language information according to the result of handling the short message;
In implement, the SMSC may first generate a delivery status report according to the existing technology. And then translate message content of the delivery status report based on the TP_LANGUAGE. Then, the SMSC may insert the translated message content into the delivery status report.
Or, when the SMSC generates the delivery status report, the message content of the delivery status report may be generated with the language indicated by the TP_LANGUAGE directly.
Step 506, the SMSC sends the delivery status report with the language indicated by the language information.
In this implement way, the SMSC extracts TP-LANGUAGE and record the language information carried in the TP-LANGUAGE against the identifier of the short message. The message content is in English or Chinese or any other language depending upon TP-LANGUAGE field.
In this implement way, the parameter may be based on the MS's language setting, or based on user selection. This language selection (with TP-LANGUAGE) can be based on terminal's language setting. It can be also user select.
In one optional case (option 1: Auto select), this can be based on terminal language setting. If terminal's language is English, then terminal will consider it as English and will do auto add of TP-LANGUAGE parameter for English. If the user changes the terminal's language to Chinese, then terminal will do auto add of TP-LANGUAGE parameter for Chinese
In another optional case (option 2: User select), User terminal can provide option in UI (User Interface) to select this. TP-LANGUAGE parameter will be English or Chinese or any other language based on selection.
In another optional case (Option 3), both the auto select and the user select can be used and the user select can have higher priority than the auto select.
In this implement way, based on above selection, terminal will add TP-LANGUAGE

parameter in SMS-SUBMIT.
Figure 6 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention; Figure 7 is another flowchart of the method for handling delivery status report in accordance with an embodiment of the present invention.
As shown in Figure 6, the value of the TP-LANGUAGE is "0", this means the language is English; so that TP-User-Data of SMS-STATUS- REPORT is "Delivered".
In this case, English user requests for delivery status report in English language. The message was delivered by SMSC. SMSC sends TP-User-Data content in delivery status report as DELIVER. So he knows the SMS has been delivered successfully. If he received in Chinese, he would not have understood if the SMS was delivered to destination.
As shown in Figure 7, the value of the TP-LANGUAGE is "1", this means the language is Chinese; so that TP-User-Data of SMS-STATUS- REPORT is "D D".
In this case, Similarly, Chinese user requests for delivery status report in Chinese language. The message was delivered by SMSC. SMSC sends TP-User-Data content in delivery status report as DEI. So he knows the SMS has been delivered successfully. If he received in English, he would not have understood if the SMS was delivered to destination.
In this embodiment, wherein the method further includes: the SMSC may send the delivery status report with default language if the language information is not included in the short message.
In an implement way, If no Language_For_Delivery_Receipt TLV, then SMSC will send message content with default language at SMSC.
In another implement way, If no TP-LANGUAGE field, then SMSC will send message content with default language at SMSC.
In this embodiment, it will save resources as SMSC does not need to maintain this user information for each subscriber; and performance will be improved as no need to search subscriber information.
Furthermore, sender (user) satisfaction will be improved as he will be able to know final delivery status of the SM; and operator maintenance cost will reduce as operator does not require to provision for this information.
Furthermore, it helps users of different languages to use the same handset without provisioning each time; and during emergency, if user doesn't have a balance to call, he can use SMS with delivery status report to communicate the dear ones.
It can be seen from the above embodiment that: by adding language information in the short message, the sender will request delivery status report at specific language without provisioning to SMS system. Furthermore, this will help to use a same handset by different user and request for delivery status report at specific language.
