In the time that SMSC issues MT note to terminal, go up query routing information according to MSISDN to terminal attaching HLR, inquiry obtains corresponding MSC address, when SMSC obtains behind the residing MSC of mobile terminal address, note to be sent is sent to mobile terminal by described MSC; But mobile terminal, due to various reasons, is not the normal note that receives of total energy.
Embodiment mono-
As shown in Figure 3, the note transmission method embodiment of the embodiment of the present invention one is as follows:
S301, MSC know that note sends wrong (MT error);
For example, in the time that mobile terminal cannot normally receive note (not start, not in signal coverage, internal memory is full, cannot receive new note etc.), its corresponding MSC can know that after transmission note described note sends error message;
Concrete, note sends error message can be by the pending datas such as information (MWD, message waiting data) state information represents, MWD state generally comprises two kinds of failure cause marks below: 1, terminal memory size exceeds mark (Mobile-Station-Memory-Capacity-Exceeded-Flag), this mark represents that the internal memory of mobile terminal is full, does not have space to receive new note again; 2, the unreachable mark of mobile terminal (Mobile-Station-Not-Reachable-Flag), this mark represents that the reason that cannot send note is to find destination mobile terminal.Those skilled in the art are known, for MSC, can determine that described MWD state is that mobile terminal is unreachable by the response timeout time is set, or the information of replying by terminal determines that memory size has expired state etc., as for concrete definite mode, the embodiment of the present invention does not limit at this.
S302, MSC pass through the MWD state information of preserving, terminal MS ISDN number, and SMSC address and their corresponding relation, notice SMSC note sends unsuccessfully (ST SM FAIL);
In an embodiment of the present invention, MSC can be in the time that note sends unsuccessfully, preserve receiving terminal Mobile Subscriber International ISDN Number, SMSC address, MWD state information and their corresponding relation, and receiving that terminal recovery receives after SMS capability notification message, according to the information of the Mobile Subscriber International ISDN Number of terminal and above-mentioned preservation, send and remind (alert) message to corresponding SMSC, there is the MSC of above-mentioned functions, be referred to as to support the MSC of quick prompting function (fast alert).In prior art, MSC does not preserve described MWD state information, terminal MS ISDN number, SMSC address and their corresponding relation, but directly by MT short message sending status notice SMSC, then SMSC reinforms the transmission state of MT note described in HLR, by HLR by MWD state information, terminal MS ISDN number, SMSC address and their corresponding relation save, can receive note in order to terminal time, the judgement terminal note accepting state that HLR can be correct also sends to corresponding SMSC by reminder message.
S303, SMSC receive the described note transmission failed message that MSC sends;
Further, SMSC can judge whether described MSC supports quick prompting function, if the judgment is Yes, described note is not sent to failed message notice HLR, proceeds to step S304;
Concrete, SMSC can judge whether described MSC supports quick prompting function according to the address of the MSC in described note transmission failed message, for example, in SMSC, configure a MSC table, the MSC in this table supports quick prompting function, like this, SMSC is as long as according to the MSC address receiving, inquire about described MSC table, judge that described MSC whether in table, can confirm whether this MSC supports quick prompting function;
In addition, MSC can send in failed message or other signalings and carry the mark of whether supporting quick prompting function in described note, SMSC can judge whether MSC supports quick prompting function according to described mark, for example, MSC can pass through at MAP version negotiation process (MAP version negotiation), identify it and whether support quick prompting function, for example, version V has identified this MSC can support quick prompting function;
Certainly, do not support quick prompting function if SMSC judges described MSC, note is sent to failed message notice HLR.
The notification message that is ready to receive note that S304, MSC mobile terminal receive send, according to the Mobile Subscriber International ISDN Number of terminal MS ISDN number and described preservation, SMSC address, MWD state and their corresponding relation, confirmation need to send note to terminal, and generation reminder message sends to the SMSC corresponding to SMSC address of described preservation;
For example, when terminal can receive (start again after note, get back to network's coverage area, memory headroom is more than needed), can send the message that is ready to receive note (readyforSM) to the MSC at terminal place, owing to preserving Mobile Subscriber International ISDN Number in MSC, SMSC address, MWD state and their corresponding relation, MSC can confirm SMSC address and MWD state according to Mobile Subscriber International ISDN Number, MSC exists and does not also send successful note according to this terminal of MWD state confirmation, and find SMSC address according to described canned data, MSC will send prompting (alert) message informing SMSC.In embodiments of the present invention, recover to receive after SMS capability in terminal, MSC can send reminder message (alert) to SMSC, avoided SMSC and HLR alternately.
S305, SMSC receive prompting (alert) message that described MSC sends, and note is sent to mobile terminal.
SMSC receive resend note flow process after reminder message and prior art similar, the embodiment of the present invention is not repeated herein.
The scheme of the embodiment of the present invention, because MSC is in the time that terminal is recovered note receiving ability, can be directly initiate to remind (alert) to SMSC, thereby it be higher to make to retransmit the efficiency of note, expends time in shorter, further, by being judged by SMSC whether MSC supports quick prompting function, if the judgment is Yes, described note is not sent to failed message notice HLR, thereby reduce the Signalling exchange of SMSC and HLR, saved the network bandwidth.
