Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. 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. 1 is a schematic flow chart of a wireless data transmission method according to an embodiment of the present invention, as shown in fig. 1, including:
101. detecting the current service type and a data packet sent by the current service;
102. and if the current service type is detected to be the precise control service and the data packet sent by the current service does not need to be segmented, adopting a rapid delivery mechanism to carry out wireless data transmission, wherein an RLC layer and an MAC layer are scheduled in the same task in the rapid delivery mechanism, and the data packet processed by the RLC layer is directly delivered to an application layer.
It should be noted that the execution subject of the embodiment of the present invention is a base station side, specifically, an MAC layer of the base station side, and an application scenario targeted by the embodiment of the present invention is mainly a precise control service in a private power network, but other application scenarios may also use the data transmission method provided by the embodiment of the present invention, and the embodiment of the present invention is not limited specifically.
Specifically, in step 101, it can be understood that, for different service scenarios, different data transmission processes may be adopted in the embodiment of the present invention, for example, for the characteristics of strict delay requirement, small data amount, and single packet transmission in the fine control service, the embodiment of the present invention needs to adopt a matched data transmission mechanism to meet the requirements of the service characteristics, and then, firstly, the current service scenario needs to be identified and the data packet transmitted by the current scenario needs to be detected. The embodiment of the present invention mainly includes two aspects, the first aspect is identification of a current service scenario, and the first aspect is that a base station side MAC layer multiplexes downlink Data, determines that the Data is a downlink Data Radio Bearer (DRB), and then detects a QCI (qos Class identifier) value of a current service, where it can be understood that the QCI value is used to specify a control Bearer level packet forwarding manner defined in an access node, and in the embodiment of the present invention, different QCI values are defined for different service scenarios, so that a current service scenario type can be detected by the QCI value. Second, in the embodiment of the present invention, a data packet transmitted by a current service is detected, where the detection process may include detection items such as message continuity determination, message length determination, downlink buffer data amount determination, and the like, and the data transmission type to be used is determined in combination with a service scenario and a data packet detection result.
Further, in step 102, because the scenario of the embodiment of the present invention is mainly directed to an accurate control service in a private power network, for the characteristics of low latency, small data volume, and single packet transmission required for the scenario, the embodiment of the present invention improves the existing protocol stack and data transmission mechanism, and performs wireless data transmission by using the fast delivery mechanism preset in the embodiment of the present invention. Fig. 2 is a schematic diagram illustrating comparison of terminal protocol stack transmission provided in the embodiment of the present invention, and as shown in fig. 2, the left side is a fast delivery mechanism adopted in the embodiment of the present invention, and a delivery manner of the fast delivery mechanism can be directly and quickly delivered from an MAC layer to an application layer. The right side is a protocol stack transmission mode provided by the prior art, and it can be understood that, firstly, the transmission from the MAC layer to the RLC layer needs to be performed with inter-service switching and transmitted through a message queue, generally having a 2ms delay, and then the data serial transmission from the RLC layer to the PDCP layer has a 1-2ms delay. The time delay of the rapid delivery mechanism provided by the embodiment of the invention can be controlled within 1ms in total. As can be seen from comparison with the content in fig. 2, the fast delivery mechanism provided in the embodiment of the present invention can significantly shorten the data transmission delay, and better meet the delay requirement of the fine control service. As can be seen from the content of step 101, in the embodiment of the present invention, the current service type and the data packet sent by the current service are detected, and then the base station side determines whether to trigger the fast delivery mechanism according to the detection result of the current service type and the data packet sent by the current service. The detection result needs to satisfy two conditions, the first is to detect that the current service scene is the fine control service, and the second is to detect that the data packet does not need to be segmented, which can be understood that the data packet does not need to be segmented, that is, the data packet is transmitted as a single packet, and the detection result meets the characteristics of the fine control service.
The wireless data transmission method provided by the embodiment of the invention simplifies the protocol stack aiming at the requirement of the precise control service, directly adopts the rapid delivery mechanism to deliver the data to the application layer, and eliminates the transmission delay caused by the serial transmission of the RLC layer recombined data packets to the PDCP layer.
On the basis of the foregoing embodiment, the detecting the current service type and the data packet sent by the current service includes:
and detecting the current service type, the message continuity of a data packet sent by the current service, the message length and the downlink cache data volume in a preset detection window.
As can be seen from the content of the above embodiment, in the embodiment of the present invention, for a service scenario of a fine control service in a private power network, a base station side needs to detect a current service type and a data packet sent by the current service to determine whether to trigger a fast delivery mechanism for data transmission. Then, in this scenario, the specific detection process is to detect each item in a preset detection window, and the detection content mainly includes: the type of the current service, the message continuity of a data packet sent by the current service, the message length and the downlink cache data volume. Specifically, the embodiment of the present invention determines whether the current service type is the fine control service according to the QCI value, detects the continuity of the packet according to the number of the arriving packets within a preset time period, to determine whether the packet is a single packet, and detects whether the length of the packet is within the downlink TBS setting, thereby ensuring that the packet can be transmitted by one scheduling, without performing segmentation processing on the RLC layer, and detecting whether the size of the downlink buffer data amount is zero.
On the basis of the above embodiment, if any one of the detection results of the current service type, the message continuity of the data packet sent by the current service, the message length, and the downlink cache data volume does not satisfy the preset condition, the wireless data transmission is performed by using a conventional delivery mechanism.
It can be known from the content of the above embodiment that, in the embodiment of the present invention, whether the current data transmission triggers the fast forwarding mechanism for forwarding is determined by detecting the current service type, the message continuity of the data packet sent by the current service, the message length, and the downlink cache data amount. Correspondingly, if any one of the previous service type, the message continuity of the data packet sent by the current service, the message length and the downlink buffer data volume does not meet the requirement, that is, the requirement of the precise control service cannot be met, the data transmission does not need to be carried out quickly, in order to save resources, the existing traditional transmission mechanism can be adopted to carry out wireless data transmission, the traditional transmission mechanism is as shown in fig. 2, tasks are switched from the MAC layer to the RLC layer, then the RLC layer is serially sent to the PDCP layer, and finally, in the network interface transparent transmission mode, the MCA is used for transmitting the data to the application layer.
On the basis of the above embodiment, detecting that the data packet sent by the current service does not need to be fragmented includes:
and in the preset detection window, when the continuity of the message is detected to be single packet, the length of the message is less than or equal to the size of a downlink transmission block TBS and the downlink cache data volume is zero, judging that the data packet sent by the current service does not need to be segmented.
As can be seen from the above description, the embodiment of the present invention detects the data packet in the preset detection window. The detection items comprise message continuity, message length and downlink cache data volume. For the continuous detection of the message, since the main characteristic of the fine control service is that a single packet is sent and the data volume is small, in the preset detection window, the embodiment of the present invention sets that the data packet arriving within the preset time length is less than 1, that is, the data packet is transmitted as a single packet, and preferably, the preset time length is 50 ms. For the message length detection, the requirement is satisfied when the detected message length is not greater than the downlink TBS, and it can be understood that when the detected message length is not greater than the downlink TBS, it can be guaranteed that the message can be transmitted by one-time scheduling, and the segmentation processing is not performed in the RLC layer. For the downlink buffer data amount detection, it is determined that the data packet sent by the current service does not need to be segmented when the downlink data buffer is zero, and it can be understood that, when a new data packet is received when the downlink buffer data amount is not zero, data segmentation or concatenation may be caused, and it is not possible to ensure that single packet data is completely sent, so that the downlink data buffer is required to be zero.
On the basis of the above embodiments, the performing wireless data transmission by using a fast delivery mechanism includes:
analyzing the data packet to obtain an FI field of a PDU data format of an RLC layer protocol data unit;
and if the value of the FI field is zero, analyzing the head of the RLC layer PDU, and sending a Service Data Unit (SDU) in the RLC layer PDU to the application layer according to an analysis result.
As can be seen from the content of the foregoing embodiments, the embodiments of the present invention adopt a fast delivery mechanism for wireless data transmission in a fine control service scenario, and in this mechanism, the embodiments of the present invention firstly analyze a data packet, and determine an FI (framing info) field of a data format of a protocol data unit PDU in an RLC layer, and it can be understood that information in the FI field indicates whether the PDU is segmented in the RLC layer.
Further, when the value of the FI field is 0, the PDU is indicated not to be segmented in the RLC layer, the header of the PDU in the RLC layer is parsed, and finally, the SDU in the PDU in the RLC layer is delivered to the application layer according to the parsing result to complete data transmission.
On the basis of the above embodiment, after the wireless data transmission is performed by using the fast delivery mechanism, the method further includes:
and updating the related parameters of the RLC layer.
As can be seen from the above description, the fast delivery mechanism adopted in the embodiments of the present invention directly transmits data to the application layer after the RLC has processed the data packet. Therefore, in order to ensure that data is correctly processed according to the conventional protocol stack flow, the embodiment of the present invention updates the related parameters of the RLC layer after the data, thereby ensuring the stability of data transmission.
