When being communicated between communication equipment, indeed through what is carried out in each protocol layer transmitting data packet, each agreement
Layer constitutes protocol stack.Wherein, necessary between the participant of communication equipment in order to make data complete to transmit between communication equipment
Identical rule of communication is followed, this set rule is known as agreement.LTE protocol stack is different according to the type of message of transmission, can be divided into
User-plane protocol stack and control plane protocol stack.The object of chain of command agreement stack carrying is control signaling；User face protocol stack
The object of carrying is user data.The EMS memory management process that Fig. 1 is communicated between protocol layer a kind of in the embodiment of the present application is corresponding
LTE protocol stack in user-plane protocol stack architecture diagram, Fig. 2 be communicated between a kind of protocol layer in the embodiment of the present application it is interior
Deposit the architecture diagram that plane protocol stack is controlled in the corresponding LTE protocol stack of management method.Wherein, it is wrapped in Fig. 1 user-plane protocol stack
The communication equipment included has: user terminal (User Equipment, UE), evolved base station (Evolved Node B, eNodeB),
Fourth generation mobile phone mobile communication standard core network (EPC).The communication equipment for including in Fig. 2 control plane protocol stack has:
UE,eNodeB.Specifically, user-plane protocol stack includes: physical layer PHY, multiple access access channel layer MAC, radio link layer control
Preparative layer RLC, packet data convergence protocol PDCP, radio resource control layer RRC, Non-Access Stratum NAS；Control plane protocol stack packet
It includes: PHY, MAC, RLC, PDCP, RRC.
LTE is applied in each network system, for example, cloud wireless access network (Cloud-Radio Access
Network, C-RAN) it is a kind of based on the green of collaborative radio, centralization processing and real-time cloud framework of China Mobile's proposition
Color wireless access planar network architecture.In order to solve the serious problems such as the high density base station deployment bring wasting of resources and inter-cell interference,
This centralized architecture of C-RAN is come into being.
In protocol stack architecture towards C-RAN, when being communicated between protocal layers entity, communication equipment needs to handle big
The data packet of amount.In the prior art, data packet only is completed to handle by a processing core of communication equipment, however, with data
The increase of amount, single requirement for handling core and being no longer satisfied service quality.Specific requirement includes: the protocol stack uplink of communication equipment
Data processing rate peak value is 150 megabits per second, and down peak magnitude is 75 megabits per second.Meanwhile in 1 millisecond, protocol stack
It must assure that and complete upstream data processing and downlink data processing.Therefore, with the increase of data volume, single core that handles is not able to satisfy
The requirement of service quality is a urgent problem to be solved.
The embodiment of the invention provides a kind of processing methods of long term evolution LTE protocol stack data interaction, as shown in figure 3,
It corresponds to the framework of each module interaction for the processing method of long term evolution LTE protocol stack data interaction a kind of in the embodiment of the present application and shows
It is intended to.
Each module is described as follows in the framework:
Task initiator 301: for generating processing task, specific task initiator can be eNodeB, LTE access net
The key control node (Mobility Management Entity, MME) of network, gateway (Serving GateWay,
SGW)。
Data distribution module 302: corresponding protocol processes thread is distributed to for task will to be handled.
Protocol process module 303: executing the entity of processing task, including N number of thread, and per thread is unique corresponding by one
Processing core execute, therefore N number of thread altogether by N number of processing core execution.N is the integer greater than 2.
Time management module 304: for the processing time according to N number of thread, management notice is generated, and is sent to data point
Send out module 302.
Management module 305: including management main module and managing process, managing process is for controlling agreement stack state
System, generates the management instruction of processing task, and the processing time of N number of thread is sent to time management module, manages main module
The data needed for storage management process.
Scheduling time TTI thread 306: it exercises supervision and records for the processing time to N number of thread.
Control software 307: the control information reported for receiving management main module.
The step of disposing this framework is as follows:
(1) base station software protocol stack parameter is configured, outside can be read simultaneously in code while operating file in compiling
Configuration file, this mentality of designing mainly facilitate the flexible change of base station inherent parameters, avoid replacing parameter information every time, be
It modifies and recompilates in source code.Parameter in configuration file includes the Internet protocol (Internet of eNodeB
Protocol, IP) address, the IP address of MME and SGW, the level of the protocol layer entity of print log etc..Particularly, for C-
The entire bulky systems of RAN have very convenient and fast function.
(2) protocal layers entity is decoupled, a protocol layer entity, which changes, will not influence another protocol layer entity
Work guarantees that reuse of code is high when code occurs correcting or develops again.Particularly, C-RAN is because whole system is huge
Greatly, it is related to each units such as protocol stack sofeware, control software 307, MME and SGW while runs and handling corresponding relationship.From grinding
Study carefully the engineering steps such as realization and test later, joint debugging, the mode of whole system division module is operated.It is fixed first
Interface message between adopted modules, then each block code and function are not interfere with each other, as long as the change to wherein some module
The change of external interface information it is not related to, then being all the variation of itself for whole system.It is noted that especially
Ground, C-RAN protocol stack sofeware are also that each protocol layer is divided into a module, and the interaction between modules is by specific
Data distribution systems transmitted.This way keeps message between protocol layer module more general, facilitates management.For the overall situation
Property common variable, structural body, message signaling etc. can also be managed collectively, to obtain more comfortable engineering-environment and experience.
(3) timer, memory management, global variable of entire LTE protocol stack software etc. are managed by management module 305 is unified
Reason, so as to guarantee the basic scheduling time demand of 1 millisecond of LTE protocol stack data distribution systems.When memory overhead and processing
Prolonging expense all is to manage software by higher to control.Control software passes through to each C-RAN protocol stack accessing user number, object
Reason layer bandwidth, runing time and CPU usage etc. are monitored to ensure the excellent of performance.
(4) finally in order to solve the problems, such as inter-core load unevenness, by reasonable distribution resource, resource utilization is improved.Busy,
Management module can handle more processing streams using central processing unit (Central Processing Unit, CPU) resource
Journey.
(5) to improve protocol handling capability, LTE protocol software needs to be promoted each layer protocol parallel processing degree, therefore each
Layer wants independent maintenance entity information and memory information, while to release interlayer coupling in interlayer interaction, supports message asynchronous
Processing.In addition, to improve treatment effeciency, protocol software internal support multi-threading parallel process, it is therefore desirable to use special number
Interlayer data interaction is handled according to dissemination system.
To realize computing resource statistic multiplexing function, protocol software operating status and computing resource to realize it is controlled,
Therefore a management module for the control of agreement stack state is increased inside the protocol software.The module independently of each layer it
Outside, it is responsible for management protocol stack operating status and resource allocation conditions.In initial phase, CPU money is distributed for LTE internal multi-thread
Initial memory address and size are distributed for each protocol module of LTE in source；During protocol migration, it is responsible for each layer memory of collection and moves
Data are moved, select proper timing to be migrated, and restore protocol state information in target protocol entity, guarantee agreement entity can
It is migrated with correct, seamless.
The computational resource allocation of protocol stack is by control agentbased control, therefore agreement stack entities need to act on behalf of to control and provide phase
Answer interactive interface, carried out for dynamically applying for resource, uploaded state information being acted on behalf of to control, with control agency protocol stack foundation,
A series of control operations such as protocol stack migration and agreement stack deletion.In addition, protocol stack sofeware will realize that (such as memory provides computing resource
Source) self-management, thus dynamic expand and reduce capacity, support telescopic protocol stack structure.
The framework of above-mentioned steps deployment has the advantages that
(1) improve the flexibility of protocol stack: each module of protocol stack needs to have preferable flexibility and independence, agreement
Stack entities realize that an important foundation of multi-core parallel concurrent is modularization, i.e. each layer entity of protocol stack is all used as a separate single
Member operation, can concurrently carry out data packet processing, release coupling completely between protocol layer entity, use unified interlayer interface
It is communicated.In this way, it is reduced into the parallel processing granularity between data packet by original entire protocol stack rank
Level is other, can greatly promote entire protocol stack data processing capacity when amount of user data increases.
(2) inter-core load is more balanced: LTE protocol stack multicore architecture should have good internuclear balanced basis.By new
Increase processing core number, according to the statistic algorithm of time, reasonable distribution handles core.
Below with reference to Fig. 3, as shown in figure 4, for long term evolution LTE protocol stack data interaction a kind of in the embodiment of the present application
The corresponding flow chart of steps of processing method.
Step 401: the communication equipment determines the load factor of each processing core in N number of processing core of the communication equipment.
N is the integer greater than 2.
Step 402: the communication equipment receives processing task, and the processing task is distributed in N number of processing core and is born
The smallest processing core of load rate executes.
In step 401, any one in communication equipment UE, eNodeB, EPC.
The load factor of each processing core is to characterize the index of the processing core payload size in N number of processing core of communication equipment.
For example, the ratio of the maximum quantity of data packet is handled for processing core currently processed data packet number and the processing core.
In step 402, the communication equipment receives the processing task that task initiator sends, and the processing task is divided
The smallest processing core of load factor executes in the N number of processing core of dispensing.
For example, when communication equipment receives task 1, totally 10 processing core.Handle core 1, processing core 2, processing core
3, core 4, processing core 5, processing core 6, processing core 7, processing core 8, processing core 9, processing core 10 are handled；Its load factor is followed successively by,
0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.95, then it will handle processing core of the core 1 as execution task 1.
A kind of the smallest mode for handling core of determining load factor is that remaining handling duration is shortest in N number of processing core
Handle core；The residue handling duration is duration needed for processing core has handled current task.Specifically, processing core is to execute
The processing time of each independent task calculates the remaining processing time.
For example, processing core 1 has handled processing task 1 and has taken time altogether 10 milliseconds, handles 1 processing task of core when distributing to
When 2, if processing core 1 also needs 2 milliseconds of processing task task 1 is disposed, the processing time for handling core 1 at this time is 2 millis
Second.
A kind of optional implementation is that the communication equipment determines the processing chained list of the processing task, and will be described
It is corresponding with a thread to handle chained list；The processing chained list stores the execution parameter of the processing task；
The communication equipment reads the execution parameter from the processing chained list；
The smallest processing core of the load factor of the communication equipment executes ginseng according to described by executing the thread
Number, executes the processing task.
When handling core execution processing task, need to execute the processing task according to some data, these data are stored in place
It manages in chained list, it is corresponding with a thread.Processing chained list includes but is not limited to the execution parameter of the processing task.For example,
Parameter is executed to include maximum execution time, execute unsuccessfully movement etc..
Before handling core execution processing task, communication equipment can read from processing chained list and execute parameter, according to reading
The execution parameter arrived executes the processing task by executing the thread by the smallest processing core of load factor.
When the communication equipment reads the execution parameter from the processing chained list, a kind of optional implementation is as follows:
The communication equipment reads the execution parameter in the first predetermined period；
If the processing chained list is occupied when the communication equipment reads the execution parameter, the communication equipment exists
Next first predetermined period, re-reads the execution parameter.
In step 401~step 402, a kind of optional embodiment is, by following formula, to determine N number of processing
The load balancing degrees of core:
Wherein, BqFor the load balancing degrees, TmCurrent all processing have been handled for N number of processing core
The handling duration of task, TsThe sum of the handling duration of currently processed task has been handled for each processing core in N number of processing core.
For example, processing core shares 3, and the time that this 3 processing cores have executed 3 tasks is 9 milliseconds, and this 3
The time that task has respectively executed is respectively 4 milliseconds, 6 milliseconds, 8 milliseconds, therefore load balancing degrees are 2/3.
A kind of optional embodiment is that the communication equipment reports described N number of to the control software of the communication equipment
Handle the status information of core；The status information includes but is not limited to: idle, normal operation, capacity reducing can increase according to specific requirements
Add, customized status information.
Wherein, the free time, it is available to represent the processing core, and does not execute processing task currently；It operates normally and represents, the processing core
It can use, and current execution processing task；It is unavailable that capacity reducing represents the processing core, then processing task will not be distributed to the processing
Core.
In the embodiment of the present invention, by the modularization to protocol stack, the flexibility of protocol stack is improved, i.e., protocol stack is each
Module is all used as a separate unit operation, can concurrently carry out data packet processing, release coupling completely between layers,
It is communicated using unified interlayer interface.In this way, make parallel processing granularity between data packet by original entire
It is other that protocol stack rank is reduced into level, and entire protocol stack data processing energy can be greatly promoted when amount of user data increases
Power.
In the embodiment of the present invention, the communication equipment includes N number of processing core, and processing capacity is more stronger than single processing core；In addition,
The processing task received is distributed to the smallest processing core of load factor in N number of processing core and executed by communication equipment, handles task dispatching
It is lower to the time, execute the more efficient of processing task.
As shown in figure 5, a kind of processing method of the long term evolution LTE protocol stack data interaction proposed for the embodiment of the present invention
The test experiments result figure of corresponding downlink data processing speed.
Specifically test process: data are issued from the reception of protocol stack data dissemination system, data are a length of 64-1500 words of packet
The IP data packet of section, then the long data packet for using 200 and 1000 bytes of packet is sent out data packet as experimental data in test
Processing thread is given, data are finally averagely given to the user of access.Increase number of users during the test to observe lower line number
According to the peak value of processing speed.Based on above-mentioned steps, respectively in the old framework of monokaryon, monokaryon new architecture, two core new architectures, the old frame of two cores
In the case of 6 kinds of structure, four core new architectures and old framework of four cores etc., test result is obtained.Wherein old framework is the association of LTE in the prior art
The framework of stack is discussed, new architecture is the framework of Fig. 3 in the embodiment of the present invention.
Test result shows: with the increase of terminal user's number, the peak rate of system can decline, this be primarily due to be
System increases with accessing user, and the increasing of system resource allocation difficulty causes system peak to decline, and belongs to normal condition.When CPU's
When nucleus number increases, the task treatment effeciency of each core can be improved, and peak value accordingly can also increase accordingly.Therefore multi-core parallel concurrent framework
CPU core number it is more, the downlink data of protocol stack processing peak value will increase.When the access quantity very little of user, old monokaryon frame
Structure is better than new multi-core parallel concurrent framework.User's access amount is few, and system is to the of less demanding of performance, for multicore architecture,
The other problems such as intercore communication lead to not reach desired peak.The size of data scale also influences whether system descending peak value speed
Rate, when user accesses one timing of quantity, data scale is bigger, and framework parallel processing is more, and corresponding processing speed also can be faster,
To which peak rate can also improve.
In addition, the time delay of data transmission can also reflect that the performance of system, the time delay of transmission depend on system load balancing
Ability.If the problems such as time delay of transmission is smaller, data packetloss or other Data reception errors can avoid as far as possible, thus system
Performance will improve.
As shown in fig. 6, a kind of processing method of the long term evolution LTE protocol stack data interaction proposed for the embodiment of the present invention
The test experiments result figure of corresponding data transmission delay rate.
Test process: one filling packet of construction, which sends program and fills packet, receives program, constructs 10000 in advance with number
IP data packet, the length of these data packets is all 1000 bytes, and concrete configuration is as shown in table 1.Wherein, iperf is to fill packet hair
Send program.
Table 1
Packet program is filled first to issue data packet, records sending time, while being received program and being started to receive data.Work as reception
When program starts to receive data, records the received time and observe corresponding coding, the data for counting identical coding send and connect
Difference between time receiving, this difference are exactly the time delay of data transmission.Since time delay has contingency, so in test process, it is right
10000 data packets sent are averaged, and guarantee the accuracy of result.
As the result is shown according to Fig. 6:
With the increase of terminal user's number, the data transmission delay of system can be increased.
When the access quantity very little of user, the time delay of monokaryon framework is better than new multi-core parallel concurrent framework.Monokaryon framework is only
It needs to carry out serial data processing using a function, and multicore architecture needs are cut into parallel, therefore the time delay of monokaryon wants more excellent.
When the nucleus number of CPU increases, the task treatment effeciency of each core can be improved, and time delay accordingly can also improve therewith.Cause
The CPU core number of this multi-core parallel concurrent framework is more, and the data processing time delay of protocol stack is more excellent.
