Controller 131 and regional complex management platform 132, each regional agency center 14 includes a regional agency
Controller 141, regional agency NMS 142 and security isolation system 143, described on-site terminal
Civilian access node 15, described command terminal 12 and region generation it is provided with between 11 and Regional Control Center 13
Open access node 16 it is provided with, the shortwave service controller of regional control centre between reason center 14
Constituting the first load sharing territory, the regional agency controller of regional Acting Center constitutes the second load sharing
Territory.
It should be noted that said structure only lists the some necessary structure of short wave communication network, but can not
Deny that short wave communication network can also include other structures, such as emergency information service platform, civilian net the Internet
Close and the data memory node etc. of user storage data.In the present embodiment short wave communication network, the three of civilian network side
Individual shortwave service controller constitutes a load sharing territory, with each emergency information service platform, the interconnection of civilian net
Node traffic controller in gateway and civilian access node realizes entirely interconnecting connection, it is provided that accesses and exchanges control
Uniform business.Three regional agency controllers of commander side constitute a load sharing territory, save with each open access
Access service controller in point realizes entirely interconnecting connection, it is provided that access and exchange control service.Bearing of both sides
Lotus shares territory provides mutually control service.
Based on above-mentioned short wave communication network system, Fig. 2 shows the flow process of load share method, with reference to Fig. 1 and
Fig. 2, the load share method that the present embodiment provides comprises the steps:
Step S101, when service conversation initiated by needs, upstream equipment selects concrete according to load-balancing algorithm
Upstream device.
Shortwave emergency communication net has high requirement to reliability, in existing network, and different shortwave business
Controller and regional agency controller are all independent, and same on-site terminal initiates session service with command terminal
Time, it is all selected fixing shortwave service controller and regional agency controller, this can cause controller load
Uneven, and if after certain controller on session path breaks down, it is likely that occur that conversation is existing
As, this is fatal to the reliability of short wave communication network.For the equipment in this this step, in load sharing territory
Functional equivalent, each equipment all can provide complete control function, and the fault of any appliance does not affect network industry
Business runs.When needs initiation business is replied, setting of the concrete participation current sessions work in load sharing territory
Standby, upstream equipment load-balancing algorithm determine when session setup, so can be by reasonable distribution Business Stream
Amount, it is to avoid network blockage.
Upstream equipment described here and upstream device are for the calling of different directions, and the concrete equipment of indication is different.
When on-site terminal calling command terminal, described on-site terminal is caller device, and command terminal is called equipment,
Described shortwave service controller is upstream device relative to civilian access node, and civilian access node is that upstream sets
Standby, described regional agency controller is upstream device relative to shortwave service controller, described shortwave business control
Device processed is upstream equipment；When command terminal calling on-site terminal, described command terminal is caller device, institute
Stating on-site terminal is called equipment, and described open access node is upstream relative to described regional agency controller
Equipment, described regional agency controller is upstream device, and described regional agency controller is relative to described shortwave
Service controller is upstream equipment, and described shortwave service controller is upstream device.
Step S102, when in the shortwave service controller in the first load sharing territory and the second load sharing territory
Regional agency controller selected after, caller device is initiated a session request to called equipment by short wave communication network
And set up session connection, the path of this session connection keeps constant before conversation end.
After shortwave service controller and regional agency controller are selected, the session path of short wave communication network determines that
, caller device initiates a session request to called equipment and sets up session connection, and this session connection
Path keeps constant before conversation end.
For above-mentioned steps S101, with reference to shown in Fig. 3, described upstream equipment selects according to load-balancing algorithm
Concrete upstream device step, specifically includes:
Step S201, upstream equipment use endless form to select downstream according to the enabled node list of self record
Equipment.
Enabled node list downstream is preserved in each upstream equipment this locality, such as needs when on-site terminal
During calling command terminal, civilian access node preserves the enabled node list of shortwave Service control downstream,
Described shortwave service controller preserves the enabled node list of regional agency controller downstream.Work as commander
During terminal call on-site terminal, what described open access node preserved regional agency controller downstream can
With node listing, the enabled node of shortwave service controller downstream preserved by described regional agency controller
List.Then upstream equipment is for each conversation request, selects upstream device according to enabled node list circulation.
As it is shown in figure 1, on-site terminal have issued three callings, shortwave industry to the command terminal opened under access node
Business controller have selected different regional agency controllers for three times.Certainly for civilian Node Controller, it is possible to
Different shortwave service controllers is selected with each session repeating query.
Step S202, upstream equipment send conversation message to selected upstream device, and start for described choosing
The fault detect intervalometer of fixed upstream device.
After selecting upstream device according to enabled node list, the upstream device also detecting this selected is actual
Available, concrete, need startup separator to detect intervalometer.
If step S203 upstream equipment receives selected downstream before described fault detect timer expiry and sets
The standby response message returned, then stop described fault detect intervalometer, completes this upstream device and selects.
During fault detect intervalometer timing, if receiving the response message that selected upstream device returns, then
Illustrate that the upstream device of current selection can be used, then stop described fault detect intervalometer, complete this downstream and set
Alternative.
Step S204, otherwise, assert that the current upstream device selected occurs abnormal, now by this upstream device
Frequency of abnormity add up 1；
If step S205 now frequency of abnormity is more than predetermined threshold value, then assert the current upstream device selected not
Available, temporarily this upstream device is deleted from enabled node list, and startup separator recovers intervalometer,
In the described fault recovery intervalometer time-out moment every time, send status poll to all disabled upstream devices and disappear
Breath, if receive the response message that upstream device therein returns, then will return to the downstream of response message
Equipment adds in enabled node list.
If fault detect timer expiry, after i.e. timing time arrives, do not receive selected upstream device yet and return
Response message, then the current upstream device selected is likely to occur exception, and this is set the exception of upstream device
Number of times adds up 1, if frequency of abnormity is more than predetermined threshold value, then assert that the current upstream device selected is unavailable,
So need this upstream device to delete from enabled node list, show the most unavailable, it is to avoid next time is again
Select this upstream device.Startup separator recovers intervalometer simultaneously, and this intervalometer is cycle timer, time length ratio
Common heart time is long, continues timing after every end cycle, and each time-out sends state immediately and looks into
Ask message to all disabled upstream devices.If receiving what certain or several upstream device returned
During response message, then the upstream device returning response message is added in enabled node list, after participation
Load sharing select.So when temporarily or permanently property fault occurs in the equipment in somewhere, its in system
His peer device can automatically be taken over it and control function, to ensure that whole system still is able to run well, and in event
Barrier point can reactivate this equipment after recovering and participate in load sharing.
As preferably, also include after described step S205:
Step S206, after cumulative frequency of abnormity still less than or during equal to described predetermined threshold value, upstream equipment is pressed
Next upstream device is selected according to enabled node list.
If accumulative frequency does not arrives predetermined threshold value, although illustrate that upstream device does not returns response message, but the most not
Must be that upstream device breaks down, it is also possible to be that upstream device transience mistake occurs, or downstream sets
Standby momentary traffic is busy, or temporary network blocking etc., now upstream equipment selects according to enabled node list
Select next upstream device.If frequency of abnormity exceedes predetermined threshold value, illustrate probably to occur equipment fault,
Then need from enabled node list, delete this upstream device, show the most unavailable.
It addition, after regional agency controller and shortwave service controller break down, be notified that maintainer is examined
Repair, after maintenance completes, regional agency controller and shortwave service controller break down start time, all to
Corresponding upstream equipment sends startup notifying message, after upstream equipment receives startup notifying message, if on
The enabled node list of trip equipment does not exist the equipment sending startup notifying message, then this equipment is added to
In enabled node list.
Generally, after regional agency controller and shortwave service controller are selected, current business session
Path be constant, but be likely to occur described regional agency controller or shortwave service controller occur therefore
The problem of barrier, now occurs that the upstream equipment of story equipment selects next equipment according to enabled node list repeating query
And startup separator detection intervalometer, until the response message having a upstream device to return, then session is cut
Shift to return the upstream device of response message.And temporarily will appear from the upstream device of fault from available section point range
Table is deleted, and startup separator recovers intervalometer, in the described fault recovery intervalometer time-out moment every time, to
All disabled upstream devices send STATUS ENQUIRY message, if receiving what upstream device therein returned
During response message, then the upstream device returning response message is added in enabled node list.Accordingly even when
Wherein regional agency controller or shortwave service controller break down, and also can be switched to next equipment in time,
Ensure conversation stability.
Storing for data, the present invention uses Distributed Data Store Model, each regional agency center also to wrap
Including a data memory node, each Regional Control Center the most also includes a data memory node, all
The data memory node at regional agency center constitutes the distributed data-storage system of commander side, and all regions are controlled
The data memory node at center processed constitutes the distributed data-storage system of civilian network side, any one data storage joint
Point failure or damage do not affect the operation of whole data-storage system, can be recovered by a memory node
The data of whole distributed data-storage system.Liang Ge distributed data-storage system working mechanism is identical, only
It is that storage data content is different with data volume.
