Abstract
The present invention discloses a short message scheduling management method in a wireless mobile network. In the method, important time points and the duration time of each important time point are determined in a specified time period; short message retransmission strategies within the duration time of different time points are configured; the loads of a short message scheduling center are divided into multiple grades, and short message processing strategies in different loads are configured. Consequently, within the duration time of different time points, the corresponding short message retransmission strategies are used for retransmitting short messages which are temporarily stored in the network; when the loads of the short message scheduling center of the network change, the corresponding short message processing strategies are used for processing the short messages which are temporarily stored in the network according to the size of the loads. When the proposal is used, the short messages which are temporarily stored in the scheduling center can be dynamically scheduled and managed; consequently, the time of the stable operation of the system is increased, and the quality of service and the reliability of the short message scheduling center of the network are greatly improved.
Description
Technical field
The present invention relates to the short message management method in the mobile radio network.
Background technology
For mobile radio network, Public Land Mobile Network (PLMN) for example, online short message service request is kept at the control centre, by this control centre the short message in the network is carried out dispatching management, as, temporarily can not transmit success to travelling carriage forwarding message, then by temporary this message in control centre, in suitable, attempt once more transmitting.The message that is temporarily stored in the control centre will take certain resource, comprises memory source, clock trigger resource etc.Along with the message that is temporarily stored in the control centre increases, the load of control centre also increases accordingly, when load increases to a certain degree, and the decreased performance of control centre, thereby cause the Short Message Service quality to descend, therefore need adopt the method that is fit to carry out dispatching management the control centre.
Existing short message scheduling management method carries out work according to the following pattern that sets in advance: travelling carriage sends a management object (MO) short message to Short Message Scheduling Center, after Short Message Scheduling Center receives this message, be kept in control centre's internal memory, issue this message to travelling carriage or External Short Message Entity (ESME) then, when issuing when unsuccessful, (generally be configured to interim wrong error reason " subscriber absent " arranged if unsuccessful cause value is configured to " interim wrong ", " user of full mobile phone EMS memory " etc.), according to the repeating transmission stand-by period of configuration, issue this message once more, issue success or surpass the lifetime until message, this message will be deleted by the control centre from internal memory; Be configured to " permanent error " (reason that generally is configured to permanent error has " disabled user ", " telecommunication service is not supported " etc.) if issue unsuccessful mistake, then this message is deleted at once by the control centre.ESME also can submit short message to Short Message Scheduling Center, and Short Message Scheduling Center is basic identical to the processing of the processing of the short message of its submission and MO message.Different with the MO short message is, the attribute of the short message that ESME submits to also comprises regularly attribute, and promptly the control centre preserves this short message and do not issue immediately, when time is up short message design issue the time time, just issue for the first time this message.This requires Short Message Scheduling Center the clock dispatching all to be arranged to each user.
From the above, the Short Message Scheduling Center core just is retransmission mechanism.Retransmission mechanism has determined the service quality of control centre.If most of short message error reasons are interim mistake, temporary short message will increase in control centre's internal memory so, if it is short more to be configured to the interim wrong short message retransmitting time, the repeating transmission number of times of control centre is also just many more, the load of control centre is also just corresponding to increase, but the service reliability of control centre can promote.On the contrary, if most of short message error reason is a permanent error, the message of keeping in control centre's internal memory is just few more so, thereby load also just reduces, but reliability of service also just reduces.Because the short message retransmitting of existing method mechanism and treatment mechanism all pre-set, can't carry out dynamic dispatching management to the short message that is temporarily stored in the control centre according to the load variations of control centre, thereby be difficult to guarantee to provide top quality service quality for the user.
Summary of the invention
The object of the present invention is to provide the short message scheduling management method in a kind of mobile radio network, use this method to carry out dynamic dispatching management to the short message that is temporarily stored in the control centre, thereby guarantee to provide top quality service quality for the user according to the load variations of Short Message Scheduling Center.
For achieving the above object, the short message scheduling management method that is used for mobile radio network provided by the invention may further comprise the steps:
Step a: material time point and duration thereof that the superlative degree, second advanced, regular grade at the appointed time are set in the cycle;
Step b:, will not support that the type, other type of error also is revised as permanent error except that illegal user, telecommunication service for the superlative degree; For second advanced, the type of error of non-user's reason is revised as permanent error; For regular grade, except that illegal user, telecommunication service do not support that the type, other type of error all is made as interim mistake;
Step c:, retransmit or keep in the short message of Short Message Scheduling Center according to the short message retransmitting strategy that is disposed at described material time points at different levels and in the duration.
Described method also comprises following steps:
Steps d: the load of described Short Message Scheduling Center is divided into some ranks according to its size;
Step e: for the short message processing policy is disposed in described each other load of level respectively;
Step f: when there is short message in Short Message Scheduling Center, determine the load level of described control centre, and, adopt corresponding short message processing policy to handle described short message according to described rank.
The load of described Short Message Scheduling Center is to determine as parameter with the number of the occupancy of the central processing unit of Short Message Scheduling Center, memory usage, short message clock trigger.
Because the present invention can be in the duration of different time points, adopt corresponding short message retransmitting strategy to retransmit the short message that is temporarily stored in the network, and can adopt corresponding short message processing policy to handle the short message that is temporarily stored in the network according to the load size of network Short Message Scheduling Center, make the present invention to carry out dynamic dispatching management to the short message that is temporarily stored in the control centre according to the load variations of Short Message Scheduling Center, thereby increase the parallel-adder settle-out time of system, and the service quality of network Short Message Scheduling Center and reliability are improved greatly.
Description of drawings
Fig. 1 is the embodiment flow chart of the method for the invention.
Embodiment
In the actual motion of network, Short Message Scheduling Center load increase is mainly caused by two kinds of reasons: the one, and during festivals or holidays, point-to-point size of message rolls up, and may be at ordinary times many times; The 2nd, control centre's load increases suddenly in a time at random, and this situation generally is because ESME submits a large amount of message suddenly to or has a large amount of broadcasts, and the not start of a large amount of purpose mobile phone.Usually the time point that above-mentioned first kind of situation occurs can expect, for example generally in New Year's Day, the Spring Festival, May Day, ten first-class festivals or holidays, the lasting time also can expect, for example about 2 to 3 days or a week; And above-mentioned second kind of situation is at random, usually can not expect. essence of the present invention, be exactly according to above-mentioned concrete condition, dynamically adjust the repeating transmission or the processing policy of short message, thereby improve the service quality and the reliability of network Short Message Scheduling Center according to the load of Short Message Scheduling Center.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the embodiment flow chart of the method for the invention.Implement the present invention according to Fig. 1, at first material time point and duration thereof in step 1 is determined cycle fixed time in this example, promptly are time point and the duration of determining all festivals or holidays in 1 year.Then in step 2, according to the character of time point the short message retransmitting strategy is divided into different grades, and the short message retransmitting strategy in the configuration different time points duration.So that in the duration of different time points, adopt the short message retransmitting strategy of different brackets.For example, the short message retransmitting strategy is divided into three ranks, the retransmission policy of tackling when the Spring Festival is the superlative degree; Other time in red-letter day is second advanced; Be regular grade at ordinary times.Retransmission policy is normally summarized to construct to the situation of online actual motion and is formed, and other short message retransmitting strategy of three levels of this example is respectively:
Highest: most of type of errors are revised as permanent error, if be made as interim mistake, repeating transmission time lengthening.
Second advanced: the type of a few class mistakes that quantity is bigger is revised as permanent error, if be made as interim mistake, prolongs the repeating transmission time as far as possible.
Regular grade: except that types such as " disabled user ", " telecommunication service is not supported ", other type of error all is made as interim mistake, the interim wrong repeating transmission time of reasonable disposition.
Like this, Short Message Scheduling Center just can use the configuration of regular grade when normally moving at ordinary times, and when red-letter day, time point arrived, the control centre automatically switched to corresponding configuration level.And after red-letter day, time point was gone over, the control centre can automatically switch to regular grade again.
Owing to may occur the growth of load of randomness in the network, for example ESME may submit a large amount of message suddenly to, make and only can't solve the problem of dynamically adjusting short message processing or retransmission policy according to the load variations of Short Message Scheduling Center according to the expected load variations that takes place festivals or holidays, therefore in step 3, also the load of Short Message Scheduling Center to be divided into multistage, and the short message processing policy under the configuration different loads, so that adopt corresponding short message processing policy to handle the short message that is temporarily stored in the network according to the size of load.In this example, the load of Short Message Scheduling Center is divided into 4 grades, is respectively regular grade, one-level, secondary, three grades, rank is high more, and the expression load is big more.When load arrives the one-level critical value, control centre's automatic switchover retransmission policy (comprise interim bug patch is permanent error, prolongs the repeating transmission time etc.) is sent out the alarm short message to attendant's mobile phone simultaneously, notify his control centre current load, so that take the measure tackled.If control centre's load descends, when load drops to below the normal level, the control centre will return to normal retransmission policy.If load continue to be risen, load arrives the secondary critical value, so the control centre will to each connect that gateway (comprising SGW and dream net gateway etc.) request reduces or the submission that stops message up to control centre's load decline one-level.If load continues to rise, arrive three grades of critical values, Short Message Scheduling Center will initiatively clear up unessential message, for example think in this example that mobile phone is more important to the business or the message of Business-to-Business than mobile phone to the message of mobile phone, so point-to-point message of message right and wrong of cleaning, the mode of cleaning is, when this message issue once unsuccessful after deletion immediately.
Based on above-mentioned steps, be in the duration of different time points, adopt corresponding short message retransmitting strategy to retransmit the short message that is temporarily stored in the network in step 4.For example during the Spring Festival, adopt five-star short message retransmitting strategy.Simultaneously, dynamically determine the load of network Short Message Scheduling Center, adopt corresponding short message processing policy to handle the short message that is temporarily stored in the network according to the size of load in step 5.The load of described definite network Short Message Scheduling Center is that occupancy, the memory usage of the central processing unit (CPU) with Short Message Scheduling Center, the number of short message clock trigger are determined as parameter.Promptly with the number of the CPU usage of Short Message Scheduling Center, memory usage, clock trigger as input, go out the load of control centre according to certain algorithm computation.Concrete algorithm is with reference to following content in this example: at first calculate the ratio of each value, that is:
CPU usage=the get current C PU of system occupancy * 100%;
Clock trigger ratio=present clock trigger number/maximum clock trigger number * 100%;
The maximum committed memory of memory usage=current Short Message Scheduling Center committed memory/Short Message Scheduling Center * 100%;
Then according to the empirical value of on-line apparatus actual motion, obtain the weights of each value: if above-mentioned weights are made as: W1, W2, W3, if constraints is W1+W2+W3=1, the load of control centre so=(CPU usage * W1+ clock trigger ratio * W2+ memory usage * W3)/3.
Need to prove that above-mentioned short message retransmitting strategy and short message processing policy can adopt same set of strategy.
