Embodiment
The present invention is in short-message system, exhales and exhale eventually the short message flow rising of SMSC side ACTIVE CONTROL ESME.Key of the present invention is, comprises the flow restriction information of message buffering thresholding and buffer memory total amount thresholding in advance for the ESME configuration; When SMSC receives the ESME short message, judge whether the present flow rate of described ESME reaches the message buffering thresholding, if, will carry out buffer memory above the ESME short message of message buffering thresholding part, and the ESME short message of the described buffer memory of Timing Processing.
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
Figure 1 shows that implementing the present invention rises ESME and exhale and exhale eventually short message to carry out the network connection layout of short-message system module after the flow control.SMSC-MAP is the short message service processor, and the flow control nucleus module embeds wherein; SMSC-DBC is the short message data storage platform, and the short message cache module embeds wherein; SMSC-CFG is the configuration section of SMSC, SMSC-ALARM is the display part of SMSC alarm, these two parts belong to the part of operating maintenance module (OMM), mainly be and the Operation and Maintenance personnel between man-machine interface, the configuration of flow control and alarm part also join respectively in these two parts; Short Message Peer to Peer agency (SMPP AGENT) module, the access link of management ESME, and with the SMSC-MAP communication, finish the processing of AO (ESME rises and exhales) message and AT (ESME exhales eventually) message together.In addition, SMSC-MAP also with alternately/gateway MSC (IW/GMSC) links to each other, and finishes the transmitting-receiving work of travelling carriage message, comprising the processing from Mobile Originated AT message.
Fig. 2 illustrates the cut-away view of flow control nucleus module and message buffering module.The various configuration informations of the SMSC that the configuration reception submodule reception SMSC-CFG of flow control nucleus module inside sends over are comprising flow restriction information.This moment, SMSC-CFG was the client of ESME flow configuration, under windows operating system, develop, the man-machine interface that provides the ESME flow set to safeguard, and relevant configuration information is kept in the client database, can ESME flow restriction information be sent to configuration by ICP/IP protocol receive submodule by " configuration synchronization " operation.Configuration receives the server end that submodule is the configuration of ESME flow, all belongs to SMSC-OMM with SMSC-CFG.Alarm sends submodule and is responsible for sending to alarm of ESME buffered message total amount and alarm clearing information on the alerting service platform of SMSC-ALARM by ICP/IP protocol, pass through the mode notifying operation attendant of acousto-optic then, and when alarm clearing, cancel audible and visual alarm.
The timing that the timer processing submodule is mainly finished the ESME buffered message detects and sends.The flow registration is to realize that the ESME flow is judged and the major part of control with the control submodule.The event handling flow process of these two modules is being described in Fig. 4-7 respectively.
The physical store submodule is finished the data cached storage on physical medium of ESME in the message buffering module, can be in the memory cache storehouse after system restarts with the data load in the physical library, and buffered message is not lost.The memory cache submodule is safeguarded the initialization and the use in memory cache storehouse, provides the memory cache interface operable to call to flow control nucleus module and data load submodule.
Fig. 3 has shown the main flow chart of flow control nucleus module event handling.This module adopts the operating mechanism of finite state machine, and circular treatment arrives the variety of event of this module.After system powers on, set up the TCP/IP communication link of good and other module earlier, read the synchronous flow restriction information of flow configuration module then, create rising of ESME and exhale and exhale eventually the flow control information table, after configuring the timer internal that needs, the incident that just begins the various arrival of circular treatment.
The flow control information table comprises the static data and the dynamic data of ESME flow control, and static data mainly comprises the message buffering thresholding and the buffer memory total amount thresholding of configuration; Dynamic data mainly is current discharge record value of ESME and the current total amount of message buffered etc.The judgement of flow control mainly is the comparison of doing dynamic data and static data.Flow configuration synchronization incident receives the flow restriction information of configuration and is updated in the static data of flow control information table.ESME rises and exhales that flow registration and control event are handled, ESME exhale eventually flow registration and control event handle and timer event to handle be the main flow process of flow control among the present invention.
Fig. 4 has described ESME and has worked the flow registration and control event handling process of exhaling.After the flow control nucleus module is received AO message, obtain the ESME Number for access, rise to exhale at ESME and search the corresponding static data and the dynamic data of exhaling flow control that rise in the flow control meter, CurAOFlux is the AO discharge record value of the current ESME of storage, earlier this value is added up, the message buffering thresholding AOFluxLimit value that it and configuration synchronization are come compares, if do not surpass the message buffering thresholding, then carrying out normal AO handles, otherwise whether the AO message number CurAOBuffMsgNum that judges the ESME of current cache has surpassed the AO buffer memory total amount thresholding AOBuffLimit of configuration, alarm if surpass then send AO message buffering total amount, otherwise the memory cache interface buffered message that the message call cache module provides, if buffer memory success then this AO message then handle temporary transient end are observed message to Operation and Maintenance platform log otherwise send failure.
Fig. 5 has described flow registration and control event handling process that ESME exhales eventually, and it is similar to have handled the flow control of exhaling among processing procedure and top Fig. 4, just repeats no more here.Uniquely different be, to carry out the process of AT buffer memory when having chain rupture between ESME and the SMPP AGENT for AT.If the ESME chain rupture is impossible send call message, but when exhaling eventually, if the ESME chain rupture, AT message just needs buffer memory, sends after waiting the ESME link normal again, has improved ESME like this and has exhaled success rate eventually.
Fig. 6 has described the flow process that message buffered is timed processing.The processing of buffered message can be adopted the mechanism of one second timer circular treatment.When timer time arrives, if buffer memory flow switch opens, then the flow control information table of each ESME of cyclic query, handle the AO buffered message earlier, reprocessing AT buffered message continues circulation from the end position of handling last time at every turn, and timeslice withdraws to then preserving end position.For the AO message of buffer memory, judge that ESME works the present flow rate of exhaling short message and whether reaches the message buffering thresholding, if do not reach, then from buffer memory, take out EMSE and exhale short message to exhale processing.Read current ESME and work the AO message buffering thresholding AOFluxLimit that exhales processing flow CurAOFlux and configuration, calculate AOFluxLimit-CurAOFlux, result of calculation is the buffer memory AO message bar number of manageable this ESME.But for fairness, the present invention can also limit the AO bar number of the each maximum manageable buffer memorys of each ESME of each circulation, for example is restricted to 10, and the buffered message of other ESME also can obtain handling liberally like this.The AT Message Processing of buffer memory is similar handling process, and different is to need also at first to judge whether the link of this ESME is normal, if normally just handle its AT buffered message.
Fig. 7 describes is the flow process that after system restart the AO of buffer memory in the physical store platform and AT message regularly is loaded in the memory cache storehouse.Here also be to adopt the timer processing incident to realize progressively loading, buffered message is read in circulation from the physical store platform in batches, and the invoke memory cache interface is inserted in the memory cache storehouse then.Data load is to keep higher handling property when handling the buffer memory short message in the memory cache storehouse.Because the number of short of buffer memory can not determine that the buffered message bar number that each timer event need load also is limited, needs timeslice to control the duration of each loading equally.
Should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spiritual scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
