When SMSC issues the MT note to terminal, go up the inquiry routing iinformation according to MSISDN to terminal attaching HLR, inquiry obtains corresponding M SC address, after SMSC obtains the residing MSC of portable terminal address, note to be sent is sent to portable terminal by described MSC; But portable terminal is not the normal note that receives of total energy owing to various reasons.
Embodiment one
As shown in Figure 3, the note transmission method embodiment of the embodiment of the invention one is as follows:
S301, MSC know that note sends wrong (MT error);
When portable terminal can't normally receive note (for example not start, not in signal coverage, internal memory is full, can't receive new note etc.), its corresponding MSC can know that after sending note described note sends error message;
Concrete, note sends error message can be by pending datas such as information (MWD, message waiting data) state information is represented, the MWD state generally comprises following two kinds of failure cause signs: 1, the terminal memory size exceeds sign (Mobile-Station-Memory-Capacity-Exceeded-Flag), the internal memory of this sign expression portable terminal is full, does not have the space to receive new note again; 2, the unreachable sign of portable terminal (Mobile-Station-Not-Reachable-Flag), the reason that this sign expression can't send note is to find destination mobile terminal.Those skilled in the art as can be known, for MSC, can determine that described MWD state is that portable terminal is unreachable by the response timeout time is set, perhaps the information of replying by terminal determines that memory size has expired state etc., as for concrete definite mode, the embodiment of the invention is not done qualification at this.
S302, MSC MWD state information by preserving, the terminal MS ISDN number, SMSC address and their corresponding relation, notice SMSC note sends failure (ST SM FAIL);
In an embodiment of the present invention, MSC can be when note sends failure, preserve the receiving terminal Mobile Subscriber International ISDN Number, the SMSC address, MWD state information and their corresponding relation, and after receiving that terminal is recovered to receive the SMS capability notification message, according to the Mobile Subscriber International ISDN Number of terminal and the information of above-mentioned preservation, send to remind (alert) message to give corresponding SMSC, the MSC with above-mentioned functions is referred to as to support the MSC of quick prompting function (fast alert).In the prior art, MSC does not preserve described MWD state information, the terminal MS ISDN number, SMSC address and their corresponding relation, but directly with MT short message sending status notice SMSC, SMSC reinforms the transmit status of the described MT note of HLR then, by HLR with the MWD state information, the terminal MS ISDN number, SMSC address and their corresponding relation are preserved, in order to terminal can receive note the time, HLR can right judgement terminal note accepting state and reminder message is sent to corresponding SMSC.
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, then described note is not sent 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 the described note transmission failed message, for example, MSC table of configuration in SMSC, the MSC in this table supports quick prompting function, like this, as long as SMSC is according to the MSC address that receives, inquire about described MSC table, judge that described MSC whether in table, can confirm promptly whether this MSC supports quick prompting function;
In addition, MSC can send in failed message or other signalings in described note and carry the sign of whether supporting quick prompting function, SMSC can judge whether MSC supports quick prompting function according to described sign, 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, then note is sent failed message notice HLR if SMSC judges described MSC.
The notification message that is ready to receive note that S304, MSC mobile terminal receive send, Mobile Subscriber International ISDN Number according to terminal MS ISDN number and described preservation, the SMSC address, MWD state and their corresponding relation, affirmation need send note to terminal, generates the SMSC that reminder message sends to the SMSC address correspondence of described preservation;
(for example start again after terminal can receive note, get back to network's coverage area, memory headroom is more than needed), can send and be ready to receive the MSC of the message of note (readyforSM) to the terminal place, owing to preserve Mobile Subscriber International ISDN Number among the MSC, the SMSC address, MWD state and their corresponding relation, MSC can confirm SMSC address and MWD state according to Mobile Subscriber International ISDN Number, there is also the successful note of transmission in MSC according to this terminal of MWD state confirmation, and found the SMSC address according to described canned data, then MSC will send prompting (alert) message informing SMSC.In embodiments of the present invention, after terminal recover to receive SMS capability, MSC can send reminder message (alert) and give SMSC, avoided SMSC and HLR alternately.
