Description
Technical field
The present invention relates to short message and send the field, be meant a kind of method and system of short message retransmitting especially.
Background technology
In 3G network, calling terminal sends SMS message to terminal called, and said short message carries calling terminal number, called terminal number; Calling terminal sends to short message the Visited Mobile Switching Center (VMSC) at calling terminal place; By VMSC short message is sent to short message service center (SC, Short Message Center), SC stores short message; And short message is transmitted to short messaging gateway (SMS-GMSC); Said SMS-GMSC is according to the called terminal number that carries in the short message, and (HLR) carries out the short message routing inquiry to attaching position register, and said short message routing inquiry is used to inquire about the VMSC at terminal called place; HLR is according to called terminal number; The MSC Number of the VMSC at the current place of terminal called that this locality is preserved returns to SMS-GMSC, and SMS-GMSC sends to the VMSC at terminal called place to short message according to MSC Number, is transmitted to terminal called to short message by this VMSC.
Concrete, the complete flow process that sends SMS message is as shown in Figure 1, may further comprise the steps:
Step 101, SC receive the short message of the VMSC transmission at calling terminal place, and SMS-GMSC is given in the request of sending SMS message then;
Wherein, said short message request comprises short message, SC number, short message call number; Said short message call number is the numbering of SC to short message, is used to identify short message;
Step 102, SMS-GMSC are to the HLR routing inquiry request that sends SMS message, the VMSC at the current place of inquiry terminal called;
Step 103, HLR return to SMS-GMSC with the MSC Number of the VMSC at the current place of terminal called through the response of short message routing inquiry;
Step 104, SMS-GMSC do GT (Global Title) translation with MSC Number, and VMSC is given in the request of sending SMS message then;
Here, said GT translation is to convert MSC Number into SMS-GMSC and the discernible type of code of VMSC;
The short message authority of step 105, VMSC inspection terminal called is initiated paging request to terminal called then;
Here, the short message authority of said inspection terminal called is meant whether the terminal called of preserving in the VMSC inquiry VLR Visitor Location Register (VLR) has the authority that receives short message; Said paging request is that VMSC and terminal called connect;
Step 106, terminal called return page response, then are connected foundation between VMSC and the terminal called;
Step 107, VMSC send to terminal called with the short message request;
Step 108, terminal called return the response that sends SMS message to VMSC, and notice VMSC short message sends successfully; The said response that sends SMS message comprises the short message call number;
Step 109, VMSC return the response that sends SMS message to SMS-GMSC;
Step 110, SMS-GMSC will send SMS message to respond and return to SC, the SC short message that deletion has been sent according to the short message call number.
Can find out that from above-mentioned flow process in the process that short message sends, move at the terminal under two kinds of situation; May cause short message to send failure; A kind of situation is as shown in Figure 2: at SMS-GMSC when HLR carries out the short message routing inquiry, the situation that terminal called moves, detailed process is following:
Step 201, SC receive the short message of the VMSC transmission at calling terminal place, and SMS-GMSC is given in the request of sending SMS message then;
Step 202, SMS-GMSC are to the HLR routing inquiry request that sends SMS message, the VMSC at the current place of inquiry terminal called;
Step 203, HLR return to SMS-GMSC with the MSC Number of the VMSC at terminal called place through the response of short message routing inquiry;
Step 204, when SMS-GMSC carries out the short message routing inquiry, terminal called moves under the NewVMSC, and initiates position updating request to New VMSC;
Here, said position updating request comprises: the positional information of terminal called, for example sub-district etc.;
After step 205, New VMSC receive the position updating request of terminal called initiation, initiate position updating request to HLR;
Wherein, said position updating request comprises the MSC Number of called terminal number, New VMSC;
Step 206, HLR receive terminal called after the position updating request under the New VMSC, preserve the MSC Number of the New VMSC of called terminal number and correspondence, and HLR is to VMSC then; The VMSC at place initiated canceling position district's request before just terminal called moved;
Wherein, said canceling position district's request comprises called terminal number;
After step 207, VMSC receive the request of canceling position district,, return the response of canceling position district to HLR then according to the related data of the local said terminal called of preserving of called terminal number deletion;
Wherein, the related data of said terminal called comprises positional information, CAMEL-Subscription-Information of terminal called etc.;
Step 208, HLR receive the canceling position district response of VMSC, send the position to New VMSC and upgrade success response;
Step 209, SMS-GMSC do the GT translation according to the MSC Number that obtains from HLR, and VMSC is given in the request of sending SMS message;
Step 210, VMSC receive the short message request, and the short message authority of terminal called is checked, then terminal called are initiated paging request;
Here, because the related data that VMSC has deleted terminal called, VMSC can find that the user is absent, thereby causes paging failure; VMSC returns short message to SMS-GMSC and sends failure response, and said short message sends failure response and comprises the short message call number;
Step 211, SMS-GMSC receive short message and send failure response, obtain SC number, the called terminal number of local this short message of preserving according to the short message call number; The short message status report is sent to HLR;
Wherein, said short message status report comprises: SC number, called terminal number;
Step 212, HLR receive the short message status report, add short message to and send in the failure record, return to SMS-GMSC then and receive the response of short message status report;
Step 213, SMS-GMSC return short message to SC and send failure response; Short message sends failure procedures to be finished.
Another kind of as shown in Figure 3, for VMSC when the terminal called paging, terminal called moves, detailed process is following:
Step 301, SC receive the short message of the VMSC transmission at calling terminal place, and SMS-GMSC is given in the request of sending SMS message then;
Step 302, SMS-GMSC are to the HLR routing inquiry request that sends SMS message, the VMSC at the current place of inquiry terminal called;
Step 303, HLR return to SMS-GMSC with the MSC Number of the VMSC at terminal called place through the response of short message routing inquiry;
Step 304, SMS-GMSC do the GT translation according to MSC Number, and VMSC is given in the request of sending SMS message;
Step 305, VMSC receive the short message request, and the short message authority of terminal called is checked, then terminal called are initiated paging;
Step 306, at this moment, terminal called moves under the New VMSC, and initiates position updating request to New VMSC;
Step 307, New VMSC send position updating request to HLR;
After step 308, HLR receive position updating request, initiate canceling position district's request to VMSC;
Step 309, VMSC receive the request of canceling position district, and the related data of local this terminal called preserved of deletion is returned the request response of canceling position district to HLR, and ended ongoing paging,
Step 310, HLR upgrade success response to New VMSC home position after receiving the request response of canceling position district;
Step 311, VMSC end paging, cause paging failure, return short message to SMS-GMSC and send failure response;
Step 312, SMS-GMSC are to the HLR status report that sends SMS message;
Step 313, HLR receive the short message status report, add short message to and send in the failure record, return to SMS-GMSC and receive the response of short message status report;
Step 314, SMS-GMSC return short message to SC and send failure response; Short message sends failure procedures to be finished.
Also having a kind of situation is that the terminal called internal memory is full, can't receive short message, and at this moment, VMSC also can paging failure, and SMS-GMSC returns short message to SC and sends failure response.
In the prior art, in the process of sending SMS message, terminal called move to other VMSC down or internal memory full, when causing short message to send failure, can triggering short message Alert process, make the short message retransmitting that sends failure.Said short message Alert process is meant: after HLR receives New VMSC position updating request or receives the message that the internal memory of mobile terminal reporting empties; Can send failure record by the local short message of inspection; Whether inquiry has the short message at this terminal to send failure record; If have, the SC in the informing message failure record resends the short message of the transmission failure at said terminal.But because in the flow process that sends SMS message, the terminal moves to New VMSC and carries out the position renewal, and when perhaps the portable terminal internal memory had been expired, current short message service process possibly also not finish; That is to say, receive the internal memory flush message of position updating request or portable terminal of VMSC at HLR after, HLR does not also receive the short message status report of SMS-GMSC; Thereby also the short message at this terminal does not send failure record; So this moment can triggering short message Alert process, must wait terminal position renewal next time or internal memory to empty after; Just meeting triggering short message Alert process will influence the ageing and success rate that short message sends like this.

Embodiment
Basic thought of the present invention is: SC initiates the short message transmission flow via SMS-GMSC to VMSC; After VMSC confirms the terminal called paging failure, through SMS-GMSC to the SC transmission failure response that sends SMS message; SC retransmits the short message that sends failure.
Come the present invention is elaborated through specific embodiment and accompanying drawing below.
The method of short message retransmitting is as shown in Figure 4 among the present invention, and concrete steps are following:
Step 401, SC send to SMS-GMSC with the short message request, and SMS-GMSC sends to VMSC according to the short message route of inquiry with the short message request;
Concrete, SC receives the short message of the VMSC transmission at calling terminal place, and SMS-GMSC is given in the request of sending SMS message then; Wherein, said short message comprises calling terminal number, content of short message, called terminal number; Said short message request comprises short message, SC number and short message call number; SMS-GMSC inquires about the short message route according to the called terminal number in the short message to HLR; HLR is according to the MSC Number of the VMSC at the local current place of terminal called of preserving of called terminal number inquiry; MSCNumber is sent to SMS-GMSC through the route response of inquiry short message; SMS-GMSC does the GT translation according to MSCNumber, and the request of sending SMS message is to the VMSC at terminal called place.
After step 402, VMSC confirm the terminal called paging failure, through SMS-GMSC to the SC transmission failure response that sends SMS message;
Concrete, VMSC receives said short message request, after the short message authority of inspection terminal called; Initiate paging request to terminal called; After receiving the page response of terminal called, the short message request is sent to terminal called, return short message through SMS-GMSC to SC then and send response; Wherein, said short message sends in the response and comprises the short message call number, and SC receives short message and sends response, deletes said short message according to the short message call number.
If terminal called when HLR inquires about the short message route, moves to New VMSC at SMS-GMSC, terminal called can carry out the position to be upgraded; Said position is upgraded and comprised: terminal called is initiated position updating request to New VMSC, and New VMSC initiates position updating request to HLR, the VMSC that HLR belongs to before terminal called moves; Initiate canceling position district's request; The district's request of said canceling position comprises called terminal number, and the related data of the local terminal called of preserving of VMSC deletion is returned the request response of canceling position district to HLR; HLR replys the position to New VMSC and upgrades success response; So far, terminal called moves under the NewVMSC, carries out position updating process and finishes.
After VMSC receives short message, search the related data less than terminal called, the user is absent, thereby causes paging failure; Perhaps, VMSC receives said short message request, after the short message authority of inspection terminal called; When terminal called was initiated paging request, terminal called moved to New VMSC, can carry out the position equally and upgrade; Said VMSC is to the terminal called paging time; Receive the canceling position district request of HLR, VMSC ends paging, thereby causes paging failure; Perhaps, the terminal called internal memory is full, can't receive short message, causes paging failure; VMSC is to the SMS-GMSC transmission failure response that sends SMS message, and said short message sends and comprises roaming retry (RoamingRetry) indication, short message call number in the failure response.
SMS-GMSC receives said short message and sends failure response; Obtain SC number, the called terminal number of local this message of preserving according to the short message call number; To the HLR status report that sends SMS message; HLR receives said short message status report, adds short message to and sends in the failure record, and said short message status report comprises SC number, called terminal number.
Step 403, SC receive said short message and send failure response, retransmit short message.
Concrete, SMS-GMSC returns short message to SC and sends failure response, after SC receives said short message transmission failure response; Confirm to comprise the RoamingRetry indication,, obtain the short message that sends failure according to the short message call number; The short message request that will comprise short message sends to SMS-GMSC, resends short message, and flow process is identical with said process; Repeat no more at this, receive the response that sends SMS message, explain that then short message sends successfully until SC; The short message deletion that the transmission that SC preserves this locality is successful, the short message transmission flow finishes.
For realizing above method, the present invention also provides a kind of system of short message retransmitting, and is as shown in Figure 5, and this system comprises: SC 501, SMS-GMSC 502, VMSC 503;
SMS-GMSC 502, are used to receive the short message request, to HLR inquiry short message route, according to said short message route, the short message request sent to the VMSC 503 at terminal called place;
Concrete, if the user is absent, can cause paging failure; Perhaps, receive the district's request of HLR canceling position, end paging, can cause paging failure; Perhaps, the terminal called internal memory is full, can't receive short message, can cause paging failure; Accordingly, VMSC 503 sends the short message that comprises the RoamingRetry indication through SMS-GMSC 502 to SC 501 and sends failure response.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to replacement and improvement etc., all should be included within protection scope of the present invention.
