Embodiment
Below in conjunction with accompanying drawing short message of the present invention is exhaled flow controller (SM-MFLC) based on MSC end, (being called for short the SMS terminal call flow controller) and end exhale flow control methods to describe.
Fig. 1 is the network connection diagram of SMS terminal call flow controller of the present invention in short-message system.As shown in Figure 1, the present invention has increased a relatively independent network element for realizing the control of SMS terminal call flow in existing global system for mobile communications (GSM) the short-message system network architecture---the core control network element of SM-MFLC; Simultaneously, embed flow configuration cooperative module in the IW/G-MSC network element in existing GSM short-message system, the configuration of integrated SM-MFLC and alarm module in the operation and maintenance sub system of GSM short-message system.These three parts have been formed SM-MFLC, realize the controlled function of SMS terminal call flow jointly.
Be provided with timer internal in the flow control nucleus module simultaneously, regularly safeguard the dynamic flow information of MSC and the overload state information of MSC; And when the overload state of MSC is recovered, in time send the MSC overload state to the flow control cooperative module and recover notification message, also send the alarm recovery message that the MSC overload state is recovered simultaneously to the flow control alarm module.
Fig. 2 is the modular structure schematic diagram of SMS terminal call flow controller of the present invention.As shown in Figure 2, carry out communication by ICP/IP protocol between the configuration of SM-MFLC and alarm module, flow control cooperative module and the kernel control module, the specific implementation of each module and mutual concrete cooperation are described below:
SM-MFLC flow configuration module, this module is developed under Windows operating system, in order to the man-machine interface of the flow set maintenance of exhaling MSC eventually to be provided, and relevant configuration information is kept in the database, can be by " configuration synchronization " operation, the number information of MSC and flow restriction information etc. are sent to the SM-MFLC nucleus module by ICP/IP protocol and be embedded in flow control cooperative module among the SM-IW/GMSC;
SM-MFLC nucleus module and be embedded in flow control cooperative module among the SM-IW/GMSC after receiving the configuration messages that configuration module sends over, is changed the MSC status table of local core buffer, and is sent configuration synchronization response message as a result to configuration module;
The flow control cooperative module, when IW/GMSC receives SMS terminal call message, and after HLR request route obtains the address information of target MSC, the flow control cooperative module will carry out respective handling according to the MSC address, if processing is then directly transmitted by original flow process in this MSC address not in the MSC flow control meter; Else if in the MSC flow control meter, and this MSC present flow rate does not have overload, then at first send the flow registration message of this MSC to the SM-MFLC nucleus module, continue afterwards will to exhale end forwards to give target MSC by original flow process, if but this MSC present flow rate overload this moment, then exhale failure response eventually, this message no longer is transmitted to target MSC.
The SM-MFLC nucleus module after receiving the flow registration message that the flow control cooperative module sends, promptly carries out the flow registering events and handles.Also one second timer is set simultaneously, timing scan and the out-of-date flow information of removing in internal system.
The flow control cooperative module after receiving the overload notification message that nucleus module sends, changes to overload with the state curStatus of the corresponding record in the MSC status table in self module.
The flow control alarm module, this module is developed under windows operating system, in order to the man-machine display interface of exhaling the flow overload warning information of MSC eventually to be provided, highlights corresponding M SC address information, and, use for query history and statistical report form with the warning information warehousing.
Fig. 3 is the flow chart that SMS terminal call flow controller nucleus module of the present invention is handled.As shown in Figure 3, be the main handling process of SM-MFLC nucleus module.When system powers on, at first read configuration information and initialization internal memory MSC multidate information table, and foundation is connected with communication between external module, inner one second timer is set afterwards again, enter operating state afterwards, circular wait receives incident and also handles accordingly.If the reception incident is the configuration synchronization incident, then carry out the synchronous of MSC static table and internal memory dynamic table, finish synchronously, send synchronized result information to configuration module; If the timer internal incident is then carried out the processing of timer event; If the flow registering events then carries out the processing of flow registering events.
Fig. 4 is a SMS terminal call flow controller nucleus module flow registering events process chart of the present invention.As shown in Figure 4, be the flow registering events handling process of SM-MFLC nucleus module.In the flow registering events is handled, at first the MSC index that sends according to the flow control cooperative module finds corresponding record, and judge whether corresponding MSC has been in the flow overload state, if be in overload state, then send the overladen notification message of this MSC flow, the overload state of corresponding MSC record in the notice SM-MFLC cooperative module change cooperative module to transmit leg IW/GMSC; If do not have overload, then the present flow rate curFlux with this MSC record in the nucleus module adds 1, and judges that whether present flow rate value curFlux is greater than setting flow value mscFlux, if less than, represent that this MSC flow does not have overload, this event handling finishes, and continues the processing of incident; Else if greater than, represent this MSC flow overload, then earlier in system all IW/GMSC send the overladen notification message of this MSC flow, notice SM-MFLC cooperative module changes the overload state of corresponding MSC record in the module separately; Judge again afterwards whether laststate also is overload state, if not, the overload warning information of MSC then sent to the alarm subsystem of SMSC; If, represent that then this MSC is in overload state continuously, sent alarm before, this need not to send alarm; Use a state value lastStatus at last and preserve current state value curStatus, and be 1, represent overload current state value curStatus assignment.Continue to handle next event afterwards.
Fig. 5 is a SMS terminal call flow controller nucleus module timer internal event handling flow chart of the present invention.As shown in Figure 5, be the inner one second timer event handling process of the flow of SM-MFLC nucleus module.In inner one second timer time, at first search and be in overladen MSC record, and be recorded as one group with 5 and (as be less than 5, then with actual number), the flow control cooperative module of group bag in all SM-IW/GMSC sends the MSC overload and recovers message, for there not being overladen record (curStatus is 0), judges then whether laststate is overload state for current state, if then send alarm recovery message one by one to alarm module.Preserve the value of current state curStatus afterwards with laststate lastStatus, remove present flow rate value (curFlux=0) and current state value (curStatus=0) simultaneously.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those skilled in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
