Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a software topology diagram of a communication test instrument according to an embodiment of the present application, where fig. 2 includes three Digital Signal Processors (DSPs). The DSP0 and the DSP1 are respectively used for a Physical Layer (PL) to process Data of CELL0 and CELL1, the DSP2 is used for distribution of a Protocol stack software version, C0 to C2 to process CELL0, C3 to C5 to process CELL1, MAC uplink (Up Load, UL)/downlink (Down Load, DL) respectively occupy one core to process uplink and downlink services, and tasks of a Packet Data Convergence Protocol (PDCP) and an RLC are located on the same core due to small Load.
Under the current architecture, taking a cell as an example, the physical layer only uses the DSP0, and the cores 0 to 2 on the DSP2 are used for realizing the protocol stack function; if two cells are used for carrier aggregation, the physical layer uses the DSP0 and the DSP1 to process the data of the two cells respectively, and meanwhile, the cores 3 to 5 on the DSP2 are used as protocol stack function cores of a second cell. In a single-cell scenario, the grouping and grouping of data are completed by the RLC task of the C1 core, and in a dual-cell scenario, the grouping and grouping of data of the primary and secondary cells of the same user are also completed by the C1 core, and the C4 core is essentially an idle core.
The following description of the present data packaging process is given by way of example in fig. 1:
step 1: when 0us interruption of each subframe header arrives, rlc (pcell rlc) of the main cell sends Buffer Occupancy (BO) of data to be sent in the queue to the MAC. In order to reduce the performance overhead caused by message interaction, the RLC and MAC use a memory sharing mode.
Step 2: and after receiving the BO, the MAC (PCELL MAC) of the main cell carries out scheduling queuing, the BO is divided according to a specific main and auxiliary cell allocation strategy when queuing is carried out, meanwhile, the UE scheduling queuing is carried out according to the modified BO, and the grouped queuing information is copied and added with a message header to the MAC (SCELL MAC) of the auxiliary cell.
And step 3: after receiving the message in the step 2, the MAC of the auxiliary cell directly allocates resources; and after the resource allocation is finished, transmitting the resource allocation result of the auxiliary cell to the MAC of the main cell.
And 4, step 4: the MAC of the main cell checks when the latest waiting time point arrives, and if the resource allocation result of the auxiliary cell is received, the resource allocation result of the main cell and the auxiliary cell is assembled in a message and sent to the RLC of the main cell; if the resource allocation result of the auxiliary cell is not received when the latest waiting time point arrives, only sending the resource allocation result of the cell to RLC; and the RLC of the primary cell is responsible for completing the grouping of the primary cell and the secondary cell after receiving the message, and setting the transmittable mark as TRUE after the grouping is completed.
And 5: and when the MAC of the main and auxiliary cells arrives at the sending time point, checking the sending identifier, and if the sending identifier is TRUE, sending the data to PL and then sending the data from an air interface.
Through the above process of the scheme, the RLC of the primary cell completes the data packet process, the RLC of the secondary cell does not undertake any task, and the packet of Transport Blocks (TB) is completed in the C1 core. When the data amount is small, the process of data packaging may be completed before the MAC data transmission time point comes, and if the data amount is large, the process of data packaging may not be completed, thereby causing data transmission failure.
In view of this, embodiments of the present application provide a data packaging method and apparatus, which perform real-time monitoring on a load of each core, and determine a core that performs data packaging according to the load of the core, so that a data packaging process can be completed on time in an existing time sequence.
It is to be understood that the terms "first," "second," and the like in the description herein are used for descriptive purposes only and not for purposes of indicating or implying relative importance, nor order.
The embodiment of the application can be applied to a communication test instrument, and the implementation process of large data volume package is carried out on the basis of the communication test instrument scene.
Fig. 3 is a flowchart of a data packaging method according to an embodiment of the present application, and referring to fig. 3, the method includes:
s301: and acquiring the load value of the current core.
In the embodiment of the present application, the current core is one of the cores included in the digital signal processor DSP where the protocol stack is located. Corresponding to C0-C5 in the DSP shown in FIG. 2, namely, the current core is one of C0-C5.
S302: and when the data package request message is received, determining a data package strategy according to the load value of the current core.
In one possible implementation, the policy of the data set package may be determined according to the following:
comparing the load value of the current core with a set threshold value; if the load value of the current core is larger than the set threshold value, a first data packet strategy is adopted for data packet packing; and if the load value of the current core is smaller than the set threshold value, performing data packet by adopting a second data packet strategy.
In some embodiments, data packaging with the first data packaging policy comprises:
determining identification information of a load sharing core;
sending a group package request message to a core corresponding to the identification information of the load sharing core;
and when determining that the confirmation message sent by the core corresponding to the identification information of the load sharing core is received, performing data packet packing by using the core corresponding to the determined identification information of the load sharing core and the current core.
In this embodiment of the present application, the load value of the current core may be compared with a set threshold, and when the load value of the current core is greater than the set threshold, the load sharing core may be selected, and a group package request is sent to the load sharing core, a group package task is shared to another core, and then the self core and the sharing core complete the group package task together. And if the load value of the current core is smaller than the set threshold value, the current core completes the packaging task by itself.
S303: and packing the data according to the determined data packing strategy.
When the data package strategy is a first package strategy, the package task can be completed through the core and the sharing core; when the data package strategy is the second package strategy, the package task can be completed through the core.
According to the data packaging method provided by the embodiment of the application, the load value of the current core is obtained, and the current core is one of the cores included in the DSP where the protocol stack is located; when receiving a data packaging request message, determining a data packaging strategy according to the load value of the current core, and packaging data according to the determined data packaging strategy, so that when the data volume is large, a packaging task can be completed within a set time, and the success rate of data transmission is improved.
Preferably, the load sharing cores in the embodiment of the present application include at least one core, that is, one or two load sharing cores may be provided, but the number of the load sharing cores may not exceed 5 (since there are only 6 cores in total, there are at most 5 cores that can share in addition to itself).
In one possible embodiment, the identification information of the load sharing core may be determined as follows:
acquiring load values of all cores included in a Digital Signal Processor (DSP) where a protocol stack is located;
sorting the load values of all cores according to a preset strategy to obtain a sorting result in a certain order;
and selecting the identification information of the load sharing core corresponding to the load value from the sorting result.
In this embodiment of the present application, the load values of all cores may be sorted according to a preset policy, for example, sorted from large to small or from small to large, and then the core corresponding to the smaller load value is selected from all load values. For example, assume that the load values of the cores are arranged in order from large to small: 60. 50, 45, 30, 20, 10, then cores with a load value of 10 and/or a load value of 20 may be selected.
For example, the comprehensive load of each core may be calculated according to a certain weight, and then the comprehensive loads are sorted. It is understood that the preset strategy is not limited to the examples illustrated in the present application, and other strategies may be used, which are not limited in the present application.
Of course, it is understood that the magnitude of the load value and the selected core are not limited to the above examples.
Further, before performing data package by using the core corresponding to the determined identification information of the load sharing core and the current core, the method further includes:
and determining to receive a response message of data copy completion sent by the core corresponding to the identification information of the load sharing core.
And the data copying is carried out by utilizing a direct memory access DMA mode.
Compared with the mode of using the Memory copy function (MEMCPY) in the prior art, in the embodiment of the application, the data is copied by using a Direct Memory Access (DMA) mode, so that the time delay of copying the data can be reduced.
Based on the above embodiments, the present application takes aggregation of two cell carriers as an example to describe the above process, and fig. 4 is a flowchart of another data packet packaging method provided in the embodiments of the present application. In fig. 4, steps 1 to 4 and step 5 are the same as those in the prior art, and are not described herein again. The description will be made mainly with respect to the method between step 4 and step 5.
(1) The main cell RLC Core1 (Core 1) firstly performs virtual package operation of the auxiliary cells TB0 and TB1 according to the resource allocation result reported by the MAC, acquires a Core number which needs to bear the copy task to the load monitoring module after completing the virtual package operation of one TB block, and if the load threshold is exceeded and the burden Core selected from the priority list is C4, C1 sends a data package request to the auxiliary cell RLC Core4 to trigger the package operation of Core 4; after the virtual package of the primary cell TB is completed, if C1 determines that the core does not exceed the load threshold, the package of the primary cell TB is completed by the core itself without performing sharing processing.
(2) And the secondary cell RLC Core4 completes actual group packing according to the virtual group packing result by using a DMA (direct memory access) group packing mode, and simultaneously sends a group packing completion response to the primary cell RLC Core 1.
(3) After receiving the response message, the primary cell RLC Core1 determines the source of the message (i.e. determines who sent the response message) according to the message header, further determines that if the data in the primary and secondary cells are moved, the RLC entity node is released, and sends a data sending request to the MAC, so that the data is sent out from the air interface.
In the embodiment of the present application, the C1 core may be understood as a decision module, and the C0, C2 to C5 may be understood as a monitoring module. The monitoring module reports a group of parameter information of the core to the decision module at regular intervals, for example, the parameter information includes CPU, IO load information, and the like, and the decision module calculates the comprehensive load of the core where each monitoring module is located according to a certain weight after receiving the parameter information and sorts the load.
Further, in the present application, the RLC downlink data processing process mainly includes two processes, i.e., a data packetization and a data transfer, and the packetization and packetization processing of the data is not independent, so that this process cannot be implemented by independent parallel processing of 2 cores, but the group TBs are independent from each other, so that the data transfer process can be processed by 2 cores (or multiple cores) respectively. Therefore, in the implementation of the scheme, a task is added to each of the other cores, the task is specially used for receiving the data sending request of the multi-core load module, the actual data copying task is completed according to the message content, and a response is replied to the decision core after the copying is completed. Meanwhile, in order to further reduce the copying time delay, DMA is adopted for all copying tasks in the scheme to replace the traditional MEMCPY scheme, and the copying performance of the scheme is further improved compared with that of the existing scheme. Specifically, as shown in fig. 5, an interactive schematic view of a load sharing module provided in an embodiment of the present application is provided, and refer to fig. 5.
In fig. 5, the C1 decision core sends a copy request to one or more copy cores, the copy cores perform a copy task after receiving the copy request, and a message is responded to the C1 core after the copy is completed. In fig. 5, O _ rlc _ DMA _ REQ indicates that the decision core sends a data COPY DMA request to the load core, O _ rlc _ MEMORY _ COPY _ RSP indicates that the load core sends a response to the decision core after completing the COPY task, O _ DDRLC _ DMA _ RSP indicates that the driver completes the COPY completion message to the local core, and OSP _ STRU _ TSM _ DMA _ TRANSFER _ ARG indicates that the local core sends a DMA COPY request to the driver. Where DD denotes a Device Driver (Device Driver).
