Description
Technical field
The present invention relates to communication technical field, refer to the method and the SMS service system of short message retransmitting in a kind of SMS system especially.
Background technology
In mobile communication, short message service (SMS, short message service) system is a passage with the signaling channel of GSM net, realizes that between user mobile phone short message transmits.In the practical application, short message is called note again, and the SMS system is called short message service center again.Existing short message service center has two types: (1) is according to regional classification short message service center, different short message service centers is responsible for the short message service of one or more administrative regions (such as districts and cities), and such short message service center is called point-to-point short message service center again; (2) according to delineation of activities short message service center, different short message service centers is responsible for the different short message service of all districts and cities.
In the process of short message issuing, owing to failure appears issuing in error reasons such as mobile phone terminal, radio congestion, user hurry, the user shuts down out server, short message will be temporarily stored in short message service center.Short message service center starts different short message retransmitting mechanism according to the different error reasons that receive, and this error reason is that terminal or switch return to short message service center.Retransmit the back user through single or multiple and may successfully receive this short message; If issue failure always, short message will be deleted after surpassing the term of validity automatically.For example, certain called subscriber's mobile phone terminal mistake (such as the mobile phone hardware and software failure) causes its short message to receive failure, this short message will be temporarily stored in short message service center, and conventional retransmission policy is: retransmit first to retransmitting 2 times in 10 minutes at interval, sent out 10 times in 2 hours at interval afterwards; If issue failure always, then retransmit operation can last till that short message service center will delete this short message automatically subsequently above slurt message validity period (such as 48 or 72 hours).It may be noted that short message service center when retransmission policy is set, need to consider the ability to bear of network, frequent repeating transmission can add the load pressure of macroreticular.
In the prior art, each short message service center only is provided with a kind of retransmission policy, the short message that remains to be retransmitted all adopts this retransmission policy, promptly this retransmission policy is applicable to all regions (may comprise a plurality of administrative regions) of this short message service center's administration or the whole zone of using certain short message service, and this retransmission policy can only be unified to revise.As can be seen, because the retransmission policy of a short message service center can only be unified to be provided with or to revise, its influence surface is a plurality of districts and cities or all districts and cities that use certain short message service, so there is following problem:
1, when the early warning of certain regional A (districts and cities or exchange area) generation resource, when needing short message service center's reduction short message retransmitting frequency or stopping to retransmit with the reduction network load, its retransmission policy can only be revised by short message service center, make the short message retransmitting mechanism of other a plurality of area B-D that this short message service center administers all be adjusted by unified, therefore the short message service of area B-D all can be subjected to unnecessary influence, after the recurrence frequency reduction, the short message arrival rate also reduces, and then the receiving short-message of user of area B-D can be affected.
2, when the switch of certain zone (districts and cities or exchange area) breaks down or paralyses, if short message still adopts conventional retransmission policy to send, the load of this switch can be subjected to more large impact, make current failure condition further worsen, the short message issuing index also can be subjected to involving more greatly simultaneously.
Generally speaking, existing short message service center can't carry out the setting of short message retransmitting strategy or parameter according to certain districts and cities or exchange area.Such as, when certain districts and cities or exchange area generation emergency case or rumour propagation, in the time of need stopping short message issuing or repeating transmission to this zone, can't be provided with special according to this regional ad hoc network situation at this regional short message retransmitting strategy.That is to say that if short message retransmitting will be yielded to the specific region, the necessity of making use of momentum has influence on the normal region; Otherwise if the situation of some specific region is ignored, the short message of these specific regions sends (even signal intelligence) and just can't improve.As can be seen, to the adjustment underaction of short message retransmitting, bring very big problem for the SMS system.
