Description
Technical field
The present invention relates to the communication system technology, particularly relate to a kind of in veneer the method for memorying data flow.
Background technology
At present, communication system is gradually towards the high integration development, and the disposal ability of communication system has obtained growth at double, has possessed the ability that more loquacity is engaged in and the carrying more business are loaded of handling.And in order to reach the purpose of handling the more business load, communication system then must have higher capacity.
For being based upon the structural communication system of single-plate grade, how reasonable store various kinds of data stream in veneer is the key factor that is related to veneer capacity and even overall system capacity.
Fig. 1 is that prior art one is by dividing the schematic diagram that permanent storage area is implemented in memorying data flow in the veneer in advance.Referring to Fig. 1, prior art one can be implemented in memorying data flow in the veneer by dividing permanent storage area in advance.When this method of application, prior art one marks off a plurality of fixed sizes in advance in the internal memory of veneer storage area is used to store different types of data flows, such as, marking off memory block A storage class is the data flow of A, memory block B storage class is the data flow of B, and memory block C storage class is the data flow of C.After veneer has obtained data flow, veneer according to the type of data flow with the storage of classifying of each data flow.Receiving type when being the data flow of A such as, veneer, is that the data flow of A is stored among the A of memory block with the type, receives type when being the data flow of B at veneer, is that the data flow of B is stored among the B of memory block with the type.
This shows, prior art one is this divide permanent storage area in advance and in veneer the method for classification memorying data flow have following shortcoming:
1, the size of the storage area that marks off is fixed, and the size how many each storage areas is set that does not flow according to different types of data, therefore, when the data flow of a certain particular type a lot, need take a large amount of memory spaces, and the data flow of other type seldom, in the time of only need taking less memory space, the size that the memory block of this specific type of data stream then can occur storing can't satisfy the storage demand of this specific type of data stream of arrival, and the memory block of storing other categorical data stream still has the situation of a large amount of residual memory spaces, thereby wasted the storage resources of veneer, reduced the veneer capacity, and then reduced power system capacity.
2, when the storage area that is used to store certain categorical data stream in the veneer can't satisfy the storage demand of the type data flow, must be by increasing the capacity that the veneer number improves system, to satisfy the storage demand of this type data flow, the number that still increases veneer then will inevitably cause the shortcoming that cost is higher and board integration is low.
Fig. 2 is prior art two is implemented in memorying data flow in the veneer by dynamic assigning memory a schematic diagram.Referring to Fig. 2, in prior art two, need not to divide in advance the operation of internal memory of single board.When veneer obtains a data flow, do not distinguish the type of data flow, in self EMS memory, open up a memory space according to the size of this data flow, and this data flow is stored in the memory space of being opened up.Receive type when being the data flow of A such as, veneer, veneer is opened up a memory space according to the size of this data flow in self EMS memory, and this data flow is stored in the memory space of being opened up.When veneer receives type when being the data flow of B, veneer is that the size of the data flow of B is opened up a memory space once more according to the type in self EMS memory, and is that the data flow of B is stored in this memory space of opening up with the type.
This shows that prior art two is this comes the method for memorying data flow to have following shortcoming by the dynamic assignment internal memory of single board:
1, because when receiving a data flow, veneer all needs to open up a memory space according to the size of data flow in self EMS memory, can consume a large amount of cpu resources and frequently open up the memory space operation, thereby reduce the processing speed of veneer widely, reduce the performance of veneer.
2, because not to the storage of classifying of various data flow, make that internal memory planning is chaotic, be difficult to use inner modes such as integer index to search and locate the data flow of a certain particular type, and be difficult to use the mode that directly reads internal memory to carry out case study and location, thereby increased maintenance difficulties greatly data stored on the boards.
Summary of the invention
In view of this, main purpose of the present invention be to provide a kind of in veneer the method for memorying data flow, make it can reduce the capacity that takies and improve greatly veneer to the veneer storage resources.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of in veneer the method for memorying data flow, may further comprise the steps:
A, determine influence the data stream type of veneer disposal ability, according to traffic model draw every kind the maximum concurrent processing number that flows of definite categorical data, wherein,
Described definite data stream type that influences the veneer disposal ability comprises: one type individual traffic in the traffic model is carried out performance test, judge when this individual traffic increases whether influential to the disposal ability of veneer, if then this data stream type is defined as influencing the data stream type of veneer disposal ability;
Described according to traffic model draw every kind the maximum concurrent processing number of definite categorical data stream comprise: according to the maximum concurrent processing Capability Requirement of system, the numerical value of all types of data flow in the traffic model is decomposed each veneer, then by analyze, the systematic function influence of the individual traffic of the definite type of test institute and verification method draw every kind the maximum concurrent processing number that flows of definite categorical data;
B, veneer are divided into different memory areas according to determined each data stream type with self EMS memory, and determine the size of the memory block corresponding with this data stream type according to the maximum concurrent processing number of data flow;
C, when veneer receives data flow, this data flow is stored in the internal memory in the memory block corresponding to this data stream type.
In step B, described maximum concurrent processing number according to data flow determines that the step of the size of the memory block corresponding with this data stream type comprises: the unit memory space that each the type data flow is required multiply by the maximum concurrent processing number of determined the type data flow in the steps A, obtains the size of the memory block corresponding with this data stream type.
In step B, veneer is carried out described division memory block and is determined the step of memory block size when starting.
Between steps A and step B, further comprise: the system parameters that determined each data stream type is defined as veneer, the maximum concurrent processing number of the data flow that drawn is defined as the numerical value of system parameters, and all system parameterss and numerical value thereof are arranged in the system parameters configuration file this system parameters configuration file of configuration in system then;
Described step B comprises:
B1, veneer obtain system parameters corresponding with self and numerical value thereof from the system parameters configuration file that system disposed;
B2, veneer are divided into different memory areas according to the different system parameter of being obtained with self EMS memory;
B3, veneer are determined the size of the memory block corresponding with this system parameters according to the numerical value of the system parameters of being obtained.

Table 2b
By showing 2a and table 2b as can be seen, in fact the system parameters configuration file of traffic model has provided required each system parameters and the numerical value thereof of veneer in the system.
After all traffic models that operator is used defined the system parameters configuration file, if when traffic model changes, the present invention's traffic model for a change defined the system parameters configuration file, with the variation of flexible adaptation Operator Specific Service.
Step 304: the system parameters configuration file of the traffic model that the current system of configuration uses in system.
Here, for an area, in a period of time, the employed traffic model of operator is fixed as a kind of, and therefore, in the present invention, the system parameters configuration file that only is required to be the traffic model of its current use of system configuration gets final product.Such as, in the Beijing area, what current operator used is traffic model 1, so, the present invention only needs the system parameters configuration file of configuration traffic model 1 in system to get final product.
Step 305: behind single board starting, system is transferred to this veneer with each system parameters and the numerical value thereof corresponding to this veneer in the system parameters configuration file of traffic model of self configuration.
Here, referring to table 1 and table 2a, such as what dispose in the current system is the system parameters configuration file of traffic model 1, so, when service processing board starts, system comprises that with each system parameters and the numerical value thereof corresponding to service processing board in the system parameters configuration file adhering to number of users is 40000, activate PDP Context number and be 30000 and static PDP Context number be 60000 etc. to be transferred to service processing board, when interface board starts, system with in the system parameters configuration file corresponding to each system parameters of interface board comprise adhere to number of users be 60000 and the RNC linking number be 5 etc. to be transferred to interface board.
Step 306: this veneer is according to each system parameters and the numerical division self EMS memory thereof that receive.
Here, because the maximum of all types of data flow that the numerical value of system parameters is veneer can receive, therefore, the various types of data of having represented veneer will receive in practical business flows the size of required memory space.The numerical value of the system parameters that veneer is received is big more, expression is big more corresponding to the required memory space of the data stream type of this system parameters, the numerical value of the system parameters that veneer is received is more little, represents more little corresponding to the required memory space of the data stream type of this system parameters.Therefore, veneer size according to each system parameters numerical value in self EMS memory is opened up a storage area for each data stream type.
Fig. 4 is the schematic diagram that the present invention divides internal memory of single board.Referring to Fig. 4, such as, the system parameters and the numerical value thereof that receive when service processing board comprise that system parameters 1 and numerical value 40000 thereof promptly adhere to number of users 40000, it is several 60000 o'clock of static PDP Context that system parameters 2 and numerical value 30000 thereof promptly activate PDP Context several 30000 and system parameters 3 and numerical value 60000 thereof, this service processing board is opened up 3 memory blocks for 3 system parameterss that receive in self EMS memory, be and adhere to user's data stream (being set at the data flow that type is A), activate the data flow (being set at the data flow that type is B) of PDP Context and the data flow (being set at the data flow that type is C) of static PDP Context and open up a storage area, memory block A respectively, memory block B and memory block C.
And this service processing board is determined the size of this memory block according to the size of the system parameters numerical value of this memory block correspondence when opening up the memory block.Because service processing board is known the size of the required unit of each data flow memory space that self receives, therefore, the size of service processing board this memory block of opening up equals to multiply by i.e. this system parameters numerical value of the type data flow maximum allowable number order corresponding to the required unit memory space of each data flow in the data stream type of this system parameters.Such as, for service processing board, be the data flow of A when opening up memory block A promptly corresponding to type at system parameters 1, the size of memory block A=each type is the numerical value 40000 of the required unit of data flow memory space * system parameters 1 of A.
Step 307: when this veneer obtains data flow, this data flow is stored in the memory block corresponding with this data stream type.
Here, referring to Fig. 4, receiving type when being the data flow of A such as, veneer, is that the data flow of A is stored among the A of memory block with the type, receives type when being the data flow of B at veneer, is that the data flow of B is stored among the B of memory block with the type.
So far, the present invention has finished according to traffic model and has divided internal memory of single board, and in each memory zone that is marked off the reasonable process of memorying data flow.
