Description
Technical field
The present invention relates to moving communicating field, particularly relate in mobile communication system flow control methods and system thereof based on service priority.
Background technology
Each functional entity of mobile communication system, system's maximum processing capability is exactly a power system capacity.When external business request during, will make system be in overload state greater than power system capacity.As this overload state not being controlled or being alleviated, systematic function will be descended rapidly, cause responding the collapse of slow, information drop-out even whole system.
(Mobile Switching Center) is example with moving exchanging center MSC, and MSC needs to handle various service request as the important network element of communication system, comprises calling, short message, switching, supplementary service or the like.Therefore the stable operation of MSC is most important.When service request surpasses the power system capacity of MSC,, can reduce the response speed of MSC so if do not control, the user continues service request because of professional not response, make MSC load higher, produced " snowball effect ", final result is exactly the MSC request of can't managing business fully.Therefore must adopt certain strategy that the overload state of MSC is controlled, prevent similar catastrophic effect, load control that Here it is.
In sum, load control system is the indispensable key technology of moving communicating field, when service request, method by the request of selectivity refusal partial service, guarantee under the overladen situation of service request, can keep system's certain processing capabilities and response speed, even if all can cause resource to be exhausted up to refusing all message.Select which kind of strategy to carry out the core content that service denial is a load control system.
Current load control strategy mainly contains two kinds:
First kind: the load class of determining system according to various parameters.Parameter can comprise CPU, memory usage, data field occupancy or the like, and load class is the load condition of current system.For different load class professional percent of pass is set respectively, in general, load class is high more, and percent of pass is low more.In service access, business is handled then, or abandoned according to load class and professional percent of pass, or normal process.
Be controlled to be example to load at MSC, load class is only determined according to CPU.Following load Control Parameter is set:
| CPU usage (percentage) | 0～75 | 75～80 | 80～85 | 85～90 | 90～95 | 95～100 |
| The MSC load level | 0 | 1 | 2 | 3 | 4 | 5 |
| Professional percent of pass (percentage) | 100 | 90 | 70 | 50 | 30 | 10 |
According to above-mentioned load Control Parameter, if current C PU is 82%, then load class is confirmed as 2 grades so, and professional percent of pass is 70%.100 call requests are promptly arranged, just should abandon 30 by 70.
This method can prevent because CPU is too high, and causes the danger of system crash, the control of loading to a certain extent, but disadvantage is arranged:
1) when system is in the overload situation, some business can initiatively be refused by system, and the user tends to attempt because of service denial reattempt, and other user can add to come in, this time can be further the overload of increasing system, vicious circle may cause system's machine of delaying like this.
2) system is provided with different load class,, must causes the change of load class so between two ranks, cause load fluctuated, produce fluctuation if load just fluctuates so.Still give an example with previous example, according to CPU usage, 75～80% is 1 grade, and 80%～85% is 2 grades.When CPU reaches 86%, load class is 2 grades, only by 70% business.Make CPU drop to 83% because having reduced percent of pass, that load class becomes 1 grade again, allows the business by 90%, traffic carrying capacity has increased again, CPU rises to 86% again, and variation has taken place again load class, just constantly fluctuation between 1 grade and 2 grades of the load of MSC like this.Therefore in order to keep the stabilized treatment ability of MSC, unavoidable ground need increase rank, and 10 grades even more, but obviously increased the complexity of system, and do not avoid above-mentioned shortcoming effectively.
Therefore, in order to overcome the existing shortcoming of first method, the second method below having occurred again:
Second kind:, system's permission service request number that inserts and the call through whether setting allows to insert are set identify, and the startup timer circulates regularly according to system loading; In each timing cycle, (also claim professional control cycle), when the ingress for service place of described communication system produces service request, judge whether described call through sign is labeled as permission and inserts; If, then refuse described service request for not allowing to insert; Otherwise insert this service request, the service request number that has inserted in the current timing cycle of accumulative total, and when this service request number that has inserted allows the service request of access to count greater than system, described call through identity marking is inserted for not allowing; And regularly the actual load of system is compared with the target load that will carry out Flow Control, revise in good time and allow access service request number and call through sign, in allowed limits the control of the load of system.Detailed content is 200410037030 referring to application number, and publication number is the Chinese patent application file " carrying out the method for flow control in communication system " of CN1691617A.
With MSC is example, is provided with to allow 100 of access service in the parameter 1 second, and the 101st later business all will be rejected so.
This method can remedy the problem of first kind of tactful load fluctuation and load vicious circle, but the shortcoming below still existing:
Professional nongraded system is to all uniform service control, if certain business burst growth so can cause other professional all failures.Through regular meeting the short message storm appearred during festivals or holidays such as the MSC system; at short notice; sending grouped short message has taken system's ample resources; make system's overload; in professional control cycle, reach total traffic load very soon, cause other business all can't insert, comprise the exigent business of real-time such as calling; this situation will produce a large amount of customer complaints, and the reputation of operator is made a big impact.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is made further more detailed description.
As shown in Figure 1, be the networking schematic diagram of mobile communication system of the present invention, the load control system that the present invention proposes can be applied in each communication entities such as MSC 20, PSTN 31, PLMN32, SGSN 33, HLR 34, BSC35, the Internet Internet 36, portable terminal 40 and go.
Wherein, HLR (Home Location Register) is an attaching position register, BSC (Basic StationController) is a base station controller, PSTN (Public Switched Telephone Network) is a public switch telephone network, PLMN (Public Land Mobile Network) is a public land mobile network, SGSN (Serving GPRS Support Node) is a Serving GPRS Support Node, and GPRS (GeneralPacket Radio Service) is GPRS.
As Fig. 2, shown in Figure 3, be load control system fundamental diagram of the present invention.
Load control system claims flow control system again, and regulation allows the service traffics sum that passes through in the unit interval, and the service request that surpasses the service traffics sum of regulation all is rejected; The expense of each professional institute consumption systems is set to professional weight, professional number of times in every class service traffics sum=unit interval * corresponding service weight.
The service traffics of system add up to miscellaneous service flow sum sum.
Increase the setting of service priority, different service priority is provided with different service traffics ratios, the business that priority is high more, it is high more that the service traffics ratio that takies is set, and guarantees that the service access of high priority under overladen situation will be higher than the business of low priority.
When service access system, judge that whether the current flow sum that has received allows the service traffics sum that inserts less than the system that is provided with, if greater than, refuse information then; Otherwise obtain this business corresponding service priority, the professional weight of this priority service and this priority service account for the ratio of total service traffics, and judge that whether flow sum that this priority service inserts allows the service traffics ratio that takies less than flow system flow sum * this priority service, if greater than, refuse information then; Otherwise the service traffics sum to current reception adds up, and the service traffics sum of this priority is added up.
Further, service traffics cycle, professional weight, service priority and the setting that takies activity ratio are dynamic, allow in system's modification in service.
In conjunction with Fig. 2, be example with MSC, the load control principle is as follows:
MSC 20 comprises load control module 22,24 two modules of Service Processing Module.When service request, at first filter by load control module 22, just can enter Service Processing Module 24 then and handle.
Among Fig. 2, when system did not have excess load, N service request remained N service request and gives Service Processing Module 24 processing after overload control module 22 is filtered.
Among Fig. 3, when system was in excess load, N service request only allowed to give Service Processing Module 24 by N1 request and handles after overload control module 22 is filtered, and remaining N-N1 service request is rejected.
As shown in Figure 4, be load control curve chart of the present invention.This figure has illustrated load control curve, and effectively load control will reach such effect exactly.Be example with MSC still, system loading is only considered CPU usage.
When constantly increase of access service request (calling or short message etc.), the CPU usage of MSC is increase constantly.When the critical value of finding to surpass certain CPU usage, when promptly arriving the load control point, load control begins to work.Service denial is constantly carried out in load control, makes CPU usage reach stable at the C point, even service request increases again, still can guarantee a stable CPU usage.Limiting case when service request reaches the M point, even refuse the also situation of excess load of all business, can't guarantee the disposal ability of system, and CPU usage is uncontrollable, sharply raises.
Load control system of the present invention, as 1 second, this timeslice was called the service traffics period T again the timeslice of the whole service time div in par aeq of system.According to every class operation flow consume system resources what,, be used for such once professional load that is spent of expression system to professional weights W of every class business setting.Total service traffics are the professional number of every class and the corresponding business weights W sum of products.Wherein the service traffics period T of system and professional weights W can dispose.
More importantly be to increase the setting of service priority P.Under the situation that guarantees the whole system performance, the business that can have precedence over low priority for the business of high priority is passed through.The principle that service priority P is set is to take into full account professional real-time and customer requirements, and service priority P can dispose; If when increasing business newly, then revise configuration and get final product.
Business setting corresponding business flow rate ratio K for the different business priority P
P, service traffics ratio K
PRepresent that this type of business can take the percentage of total service traffics.Like this, no matter how certain business increases, as long as to a threshold values, just or else allows to insert, up to next service traffics period T.
At last, when control load, whether judge earlier the current total service traffics that inserted less than the total service traffics that are provided with, and then judge that total service traffics that this priority service inserts are whether less than total service traffics * service traffics ratio K of setting
P, when these two judgements all are "Yes", just allow to insert.
Therefore, in a service traffics period T, other business of certain grade can insert maximum number and can calculate according to the example of following MSC:
Following parameter at first is set:
(1) master control parameter:
| The service traffics cycle (S) | 5 |
| Total service traffics | 300 |
(2) the professional weights W of all kinds of business and service priority P:
| Class of service | Call out | The interoffice calling | Short message | Switch | Mobile management | Supplementary service |
| Professional weights W | 3 | 3 | 2 | 4 | 2 | 2 |
| Service priority P | 4 | 4 | 2 | 4 | 3 | 1 |
(3) each service priority P corresponding service flow rate ratio K
P:
| Service priority P | 1 | 2 | 3 | 4 |
| Service traffics ratio K P(percentage) | 20％ | 25％ | 35％ | 40％ |
For short message service, can handle the short message number in the service traffics period T at most and be (total service traffics * service traffics ratio * service traffics cycle)/professional weight=188.
Even adopt this method can guarantee that the business of other priority also can insert when the message storm occurring.
As shown in Figure 5, be the flow chart of the control of loading of the present invention.In conjunction with Fig. 2,3, load control module of the present invention is described in further detail according to Fig. 5.This flow process is on the basis of " carrying out the method for flow control in communication system " patent application document, a kind of flow control implementation method based on service priority is proposed, adopt this method to make load control more reasonable, can more effectively guarantee the disposal ability of system.
When receiving service request, load control module 22 is called, and specifically comprises following several steps:
Step 501, the service traffics cycle of configuration-system is T, the total service traffics that allow in the load control system unit interval to insert are N
