The embodiment of the present invention provides a kind of data processing method for air protocol data surface.As shown in figure 3, being this hair
A kind of data processing method schematic flow sheet for air protocol data surface that bright embodiment is provided, including：
Step 301：The hardware core total number Y and base station for obtaining base station need the number of cells N for supporting.
Specifically, the quantity of the processor cores of inquiry base station, obtains hardware core total number Y.The cell that inquiry base station is supported
Number, obtains number of cells N.
Step 302：The relation of the hardware core total number Y of the number of cells N and base station supported is needed according to base station, it is determined that being used for
The hardware check figure M1 for the treatment of cell MAC layer scheduling；
Step 303：Hardware core total number Y according to base station and the hardware check figure M1 for processing the scheduling of cell MAC layer, it is determined that
For the hardware check figure M2 of processes user data, wherein, M1+M2≤Y.
Specifically, in step 302, taking a hardware core according to each cell carries out cell MAC layer scheduling, and each
Whether cell takes a principle for hardware core processes user data, determine Y more than or equal to 2N.Now, for each hardware core
Load balancing, considers each cell scheduling sets of threads individually one user scheduling of cell for the treatment of, a cell configuration one first
Individual user data sets of threads carrys out processes user data.
In Y >=2N, it is determined that be N for processing the hardware check figure M1 of cell MAC layer scheduling, it is determined that for processing number of users
According to hardware check figure M2=Y-N.
Now, cell scheduling sets of threads needs to take N number of hardware core, and remaining hardware core can be used for processes user data,
Due to Y-N >=N, i.e., remaining hardware check figure can completely or partially be used to dispose more than or equal to cell number, thus remaining hardware core
User data sets of threads, can meet a cell and at least configure a user data sets of threads to process user in the case
Data.
For example, hardware core total number Y=8 of base station, the number of cells N=3 of base station, due to Y ＞ 2N, then for processing cell
The hardware check figure M1=3 of MAC layer scheduling, for the hardware check figure M2=5 of processes user data.I.e. cell scheduling sets of threads needs
3 hardware cores are taken, remaining 5 hardware cores are used for processes user data.Wherein, 5 hardware cores are not limited to all or part of place
Reason user data sets of threads, the number of users that can be supported as needed is disposed accordingly.Preferably, a cell is at least matched somebody with somebody
Put a hardware core processes user data sets of threads.
It is two principles of cell serves according to the hardware core that a treatment cell MAC layer is dispatched in Y ＜ 2N, it is determined that
Hardware check figure M1, M1 for processing the scheduling of cell MAC layer are the integer not less than N/2；And determine for processes user data
Hardware check figure M2=Y-M1.
Now, a cell scheduling sets of threads processes two user schedulings of cell, at least needs N/2 hardware core to come portion
Administration's cell scheduling sets of threads, remaining hardware core is used to dispose user data sets of threads.
Specifically, when N/2 is not integer, it is necessary to be rounded up.For example, cell number N=3, then N/2=1.5, this
When M1 need to round up, i.e. M1=2.
It should be noted that in the case where hardware core total number Y is less, a hardware core for treatment cell MAC layer scheduling
Can also be two or more cell serves, i.e., the use of more than two cells can also be processed by a cell scheduling sets of threads
Family is dispatched, and is not limited herein.
As N≤Y-M1, i.e., remaining hardware check figure is more than or equal to cell number, and now remaining hardware core can be all or part of
For disposing user data sets of threads, a cell can be met in the case and at least configures a user data sets of threads
Processes user data.
For example, hardware core total number Y=7 of base station, the number of cells N=4 of base station, due to Y ＜ 2N, then using a treatment
The hardware core of cell MAC layer scheduling is two cell serves, i.e., one cell scheduling sets of threads processes two users of cell and adjusts
Degree, now for processing the hardware check figure M1=2 that cell MAC layer is dispatched, for the hardware check figure M2=5 of processes user data.
Due to N ＜ M2, remaining 5 hardware cores are used to process 4 user data of cell.
For another example, hardware core total number Y=9 of base station, the number of cells N=5 of base station, due to Y ＜ 2N, then using a treatment
The hardware core of cell MAC layer scheduling is two cell serves, i.e., one cell scheduling sets of threads processes two users of cell and adjusts
Degree, is now 3 for processing the hardware check figure M1 of cell MAC layer scheduling and rounding up, for the hardware core of processes user data
Number M2=6.Due to N ＜ M2, remaining 6 hardware cores are used to process 5 user data of cell.
As N ＞ Y-M1, i.e., remaining hardware check figure is less than cell number, and now remaining hardware core can completely or partially be used for portion
User data sets of threads is affixed one's name to, now a user data for user data sets of threads at least one cell for the treatment of.
For example, hardware core total number Y=5 of base station, the number of cells N=4 of base station, due to Y ＜ 2N, then using a treatment
The hardware core of cell MAC layer scheduling is two cell serves, i.e., one cell scheduling sets of threads processes two users of cell and adjusts
Degree, now for processing the hardware check figure M1=2 that cell MAC layer is dispatched, for the hardware check figure M2=3 of processes user data.
Due to N ＞ M2, remaining 3 hardware cores are used to process 4 user data of cell.
It should be noted that when N ＞ Y-M1, and N/2 are not integer, M1 can also be rounded downwards, not done herein
Limitation.For example, hardware core total number Y=6 of base station, number of cells N=5, may also set up for processing the hard of cell MAC layer scheduling
It is 2 that part check figure M1 is rounded downwards, then for the hardware check figure M2=4 of processes user data.Due to N ＞ M2, remaining 4 hardware cores
For processing 5 user data of cell.
It should be noted that in LTE system, it is up to a hundred or thousands of orders of magnitude that base station needs the number of users supported, therefore
Reasonable distribution user to each user data sets of threads is needed, each hardware core load balancing is just can guarantee that.Therefore, after step 303,
Also need to the deployment of the user of the load adjustment access user data sets of threads of hardware core according to processes user data.Based on pin
To the data processing method of air protocol data surface, the embodiment of the present invention is additionally provided and ensured respectively in the case where number of users is big
Three kinds of methods of hardware core load balancing.
Method one：According to the number of users that each user data sets of threads record is accessed, the number of users that will have been accessed is minimum
User data sets of threads as new access user user data sets of threads.
Specifically, the number of users S that each user data sets of threads record has been accessed, each user data sets of threads accesses one
S adds one during individual new user, and S subtracts one during one user of release.When accessing new user every time, selected in M2 user data sets of threads
The minimum user data sets of threads of accessed user's number S of record is selected as the user data thread of new access user.The method
It is relatively easy, easily to realize, the number of users of each user data sets of threads treatment is essentially identical, but because each customer service is different,
Data volume size is also just different, and the load of each hardware core there may be certain lack of uniformity.
Method two：
According to the CPU average loads of the affiliated hardware core in each user data sets of threads record setting duration, CPU is put down
The user data sets of threads disposed on the minimum hardware core of equal load as new access user user data sets of threads.
Specifically, each user data sets of threads records the CPU average treatment loads of the affiliated hardware core in T seconds duration.
When new user accesses, the user data sets of threads disposed on the minimum hardware core of selection CPU average treatments load is used as newly connecing
The user data sets of threads of access customer, the method relative manner one realizes complexity, but can make each hardware core load balancing substantially.
Method three：
According to the CPU average treatment loads of the affiliated hardware core in each user data sets of threads record setting duration, if
The difference of maximum CPU average loads and minimum CPU average loads exceedes given threshold, then by the hardware core of maximum CPU average loads
The user of the user data sets of threads of upper deployment adjusts to the hardware core of the minimum CPU average loads user data of deployment
Sets of threads.
The above method one and method two are all that affiliated user data sets of threads is determined when new user accesses, but user
Business datum amount size is dynamic change, although user's each hardware core load when accessing is in a balanced way, but with each user
The change of business datum amount size, hardware core load is also dynamic change.Therefore the user belonging to dynamic adjustment user is needed
Data thread group.
Specifically, the real-time CPU average treatments of the affiliated hardware core in T seconds duration of each user data sets of threads record are born
Lotus.If the difference of maximum cpu load and minimum cpu load exceedes given threshold H, by the hardware core of maximum CPU average loads
The user of the user data sets of threads of deployment adjusts to the hardware core of the minimum CPU average loads user data line of deployment
Journey group, then repeats as above dynamic adjustment process, so that the real-time CPU treatment of the affiliated hardware core of each user data sets of threads
The difference of load is no more than given threshold.The method is complex, but can make the load real time equaliser of each hardware core.
The embodiment of the present invention provides a kind of data processing method for air protocol data surface, by the way that hardware core is total
Reasonable distribution is carried out, the hardware core for the treatment of cell MAC layer scheduling is specifically divided into, quantity is M1；And processes user data is hard
Part core, quantity is M2.Reached using the class sets of threads of polycaryon processor reasonable distribution parallel processing two and meet LTE air protocol stack numbers
According to face it is high handle up, multiple cell, multi-user purpose, while make each hardware core load balancing, improve hardware resource utilization and be
System stability.
The embodiment of the present invention also provides a kind of data processing method for air protocol data surface, as shown in figure 4,
It is a kind of data processing method flow chart for air protocol data surface provided in an embodiment of the present invention, including：
Step 401：Obtain the hardware core total number Y of base station and the number of cells N of base station.
Step 402：Judge whether Y >=2N sets up, if so, then performing step 403, no person performs step 404.
Step 403：It is determined that the hardware check figure M1=N for processing the scheduling of cell MAC layer, it is determined that being used for processes user data
Hardware check figure M2=Y-N.
For example, hardware core total number Y=8 of base station, the number of cells N=3 of base station, due to Y ＞ 2N, then for processing cell
The hardware check figure M1=3 of MAC layer scheduling, for the hardware check figure M2=5 of processes user data.I.e. cell scheduling sets of threads needs
3 hardware cores are taken, remaining 5 hardware cores are used for processes user data.
Step 404：It is determined that be M1 for processing the hardware check figure of cell MAC layer scheduling, M1 is the integer not less than N/2,
Continue executing with step 405.
Step 405：Judge whether N ＞ Y-M1 set up, if so, then performing step 406, no person performs step 407.
Step 406：One user data sets of threads of configuration processes the user data of at least one cell.
