In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In the following embodiments, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," and/or the like, specify the presence of stated features, integers, steps, operations, elements, components, or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof. Also, the term "and/or" as used in this specification includes any and all combinations of the associated listed items. "plurality" refers to two or more cases, for example, 2, 3, 5, 8, etc.
The RLC layer data transmission method provided by the embodiment of the present application can be applied to an application environment as shown in fig. 1. Wherein the mobile terminal 102 may be communicatively coupled to the base station 104, and the base station 104 may be coupled to the server 108 via the access network 106 to enable communication between the mobile terminal 102 and the server 108. Under the structure shown in fig. 1, the mobile terminal 102 may transmit an uplink message to the server 108 through the base station 104, and the server 108 may transmit a downlink message to the mobile terminal 102 through the base station 104. The mobile terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, etc. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The base station 104 may be a macro base station, a micro base station, a remote radio, a repeater, an indoor distribution system, or the like, where the base station 104 may support any standard of communication signals, for example, the base station 104 may support LTE (Long Term Evolution ) and/or 5G communication standards.
Specifically, the base station 104 may be implemented based on the network protocol architecture shown in fig. 1. The network protocol architecture includes a Physical Layer (PHY), a medium access control Layer (Media Access Control, MAC), a radio link control Layer (RLC), a packet data convergence protocol Layer (Packet Data Convergence Protocol, PDCP), and a GPRS tunneling protocol Layer (GPRS Tunneling Protocol, GTP). The base station 104 may implement communications with the mobile terminal 102 based on the network protocol architecture shown in fig. 1.
In the related art, the RLC layer may operate in an RLC AM mode, which is implemented based on ARQ (Automatic Repeat-Request). Specifically, after the RLC AM mode sends the downlink message, the RLC AM mode will be placed in a corresponding queue, and based on feedback information sent by the receiving end, whether to retransmit the downlink message or whether to clear the downlink message from the queue is determined. Therefore, the RLC can be provided with a guarantee transmission mechanism, and the reliability of data transmission is improved.
However, as the background art is, the current RLC layer data processing method has a problem of slow downlink data transmission rate. The inventor researches and discovers that the problem is caused by the fact that the traditional TCP (Transmission Control Protocol ) protocol also has the guaranteed transmission capability, and the base station has overlapping coverage on the guaranteed transmission of the RLC AM and the guaranteed transmission of the TCP protocol. However, the current RLC layer does not analyze the TCP data uploaded by the mobile terminal, and has a cognitive blind spot for the information displayed in the data packet by the TCP protocol, and does not perform deep processing and optimization based on the cognitive blind spot, thereby causing a problem of slow downlink data transmission rate. Meanwhile, the existing base station has overlapping coverage in the guaranteed transmission of the RLC AM and the guaranteed transmission of the TCP protocol, and the two base stations have a plurality of agreements in the aspect of data transmission, so that the mining and development are not few.
In order to solve the foregoing problems, the present application provides a method, an apparatus, a base station, and a storage medium for RLC layer data transmission, where uplink and downlink dual-path TCP joint analysis and TCP advanced acknowledgement are performed in the RLC layer, so that transmission of downlink data can be accelerated, and a service download rate can be improved.
In one embodiment, as shown in fig. 2, an RLC layer data transmission method is provided, and an RLC entity to which the method is applied at a base station is described as an example. The method specifically comprises the following steps:
s210, the initial TCP response number of the uplink message to be transmitted on the radio link control RLC layer is obtained.
Specifically, the RLC entity may buffer the downlink packet sent by the server in a downlink buffer queue corresponding to the RLC layer, and send the downlink packet to the mobile terminal, so as to complete downlink communication between the server and the mobile terminal. The RLC entity is further configured to receive an uplink packet sent by the mobile terminal, and report the uplink packet to an upper layer (e.g., PDCP layer) to implement uplink communication between the server and the mobile terminal.
The initial TCP response number is used for indicating the data receiving condition of the mobile terminal in the current downlink transmission process to the base station/server and indicating the initial message in the next downlink transmission process to the base station/server.
Specifically, when the server and the mobile terminal communicate based on the TCP protocol, the mobile terminal sends a corresponding TCP response message to the base station according to the reception condition of the downlink message. The TCP reply message may include an initial TCP reply number that may indicate to the base station and/or the server a message sequence number of a start message sent to the mobile terminal in a next downlink transmission process. For example, as shown in fig. 3, if the RLC entity receives a TCP response message and the initial TCP response number of the TCP response message is 200, it indicates that the mobile terminal has received downlink messages with message sequence numbers 0 and 100 in the current downlink transmission process, so in the next downlink transmission process, the base station/server may send a downlink message with message sequence number 200 as an initial message, for example, send downlink messages with message sequence numbers 200, 300, 400, and 500 to the mobile terminal in sequence.
In one embodiment, the step of obtaining an initial TCP response number of an uplink packet to be transmitted on the radio link control RLC layer includes:
and analyzing the uplink message to be transmitted to obtain an initial TCP response number.
S220, determining the downlink message which is matched with the initial TCP response number in the downlink buffer queue corresponding to the RLC layer as a target message.
Specifically, the RLC entity may perform a TCP advanced acknowledgement operation in combination with a received TCP acknowledgement message based on its own downlink buffer queue. Specifically, the RLC entity stores a plurality of downlink messages in its own downlink buffer queue. Under the condition that the RLC entity acquires the TCP response message, the RLC entity determines a target message matched with the initial TCP response number.
For example, in the example shown in fig. 3, if the initial TCP response number of the uplink packet is 200, the target packet is the downlink packet corresponding to the packet sequence number 200.
S240, in response to the existence of a plurality of continuous downlink messages taking a target message as a starting message in a downlink buffer queue, updating the initial TCP response number to the target TCP response number to obtain an updated uplink message, and uploading the updated uplink message to the PDCP layer; wherein the target TCP response number is greater than the initial TCP response number.
Specifically, the RLC entity stores a plurality of downlink messages in its own downlink buffer queue. Under the condition that the RLC entity acquires the target message, the RLC entity can judge whether a plurality of continuous downlink messages taking the target message as an initial message exist in a downlink buffer queue corresponding to the RLC layer. That is, whether there are at least two downlink messages with the target message as the initial message and the message sequence numbers being continuous in the downlink buffer queue corresponding to the RLC. If yes, the RLC entity may advance the TCP response number in the uplink packet, that is, update the TCP response number of the uplink packet from the initial TCP response number to a target TCP response number greater than the initial TCP response number. The RLC entity may upload the updated uplink packet to the PDCP layer, where the TCP response number in the updated uplink packet is the target TCP response number. It will be appreciated that the target TCP response number may be a value greater than the initial TCP response number, and its specific value may be determined according to actual requirements, which is not specifically limited in this application.
Taking the example shown in fig. 3 as an example, the initial TCP response number of the uplink packet is 200, and the target packet is the downlink packet corresponding to the packet sequence number 200, in this case, the RLC entity may determine whether there are a plurality of continuous downlink packets in the downlink buffer queue using the target packet as the initial packet, and determine whether to execute the advanced response operation according to the determination. As shown in fig. 3, there are downlink messages with message numbers 200, 300, 400, 500, 600 in the downlink buffer queue, so that it can be determined that there are 5 continuous downlink messages with the target message as the initial message in the downlink buffer queue, so that the RLC entity can advance the TCP response. The RLC entity may update the TCP acknowledgement number of the uplink message from 200 to 300, 400, 500 or 600 to implement the advanced acknowledgement.
Therefore, the RLC entity can execute TCP deep analysis, monitor TCP response messages of the mobile terminal in real time, combine a downlink buffer queue corresponding to the RLC layer, compare and analyze the TCP response messages with the downlink messages in the downlink buffer queue, and advance the TCP response under proper conditions, so that the guarantee transmission of the RLC AM mode and the transmission characteristics of the TCP protocol can be fused, the transmission of the downlink data is accelerated, and the downloading rate of the service is improved.
In the RLC layer data transmission method, the base station may obtain an uplink packet to be transmitted on the RLC layer, and obtain an initial TCP response number of the uplink packet to be transmitted. If a plurality of continuous downlink messages taking the target message as a starting message exist in the downlink buffer queue corresponding to the RLC layer, updating the TCP response number of the uplink message from the initial TCP response number to the target TCP response number, and uploading the updated uplink message to the PDCP layer. The target message is a downlink message matched with the initial TCP response number, and the target TCP response number is larger than the initial TCP response number. Therefore, the transmission capacity of the base station RLC AM mode can be fully developed, and the TCP transmission characteristics are combined, so that the base station can advance the TCP response of the mobile terminal for the message responsible for the transmission by the RLC, thereby greatly reducing the transmission delay of the TCP downlink message, saving part of wireless side delay loss, further pulling the transmission of the downlink message, improving the rate of the downlink service and improving the downloaded customer experience.
In one embodiment, as shown in fig. 4, before the step of updating the initial TCP response number to the target TCP response number, the method includes:
s230, determining a target TCP response number according to the message sequence number corresponding to any one of the continuous downlink messages.
Specifically, in the case that a plurality of continuous downlink messages using the target message as a starting message exist in a downlink buffer queue corresponding to the RLC layer, the RLC entity may determine the target TCP response number according to a message sequence number corresponding to any one of the plurality of continuous downlink messages. In one embodiment, the RLC entity may use the message sequence number of the next downlink message corresponding to a certain downlink message as the target TCP response number. In another embodiment, the RLC entity may use the message sequence number of any one of the remaining downlink messages except the start message in the continuous multiple downlink messages as the target TCP response number.
For example, in the example shown in fig. 3, a plurality of continuous downlink messages with the target message as the starting message are downlink messages corresponding to the message sequence numbers 200, 300, 400 and 500, respectively, and the RLC entity may determine the target TCP response number according to the message sequence number 300. Further, when determining the target TCP response number according to the packet sequence number 300, the RLC entity may confirm the packet sequence number 300 as the target TCP response number, or may confirm the packet sequence number of the next packet corresponding to the packet sequence number 300 (i.e. the packet sequence number 400) as the target TCP response number.
In this embodiment, the target TCP response number is determined according to the message sequence number corresponding to any one of the continuous multiple downlink messages, so that the target TCP response number can be matched with the downlink message buffered in the downlink buffer queue, and the occurrence of problems such as data loss is avoided, thereby improving the reliability of communication.
In one embodiment, the step of determining the target TCP response number according to the message sequence number corresponding to any one of the plurality of continuous downlink messages includes: and determining a target TCP response number according to the maximum message sequence numbers corresponding to the continuous multiple downlink messages.
Specifically, the RLC entity may determine the target TCP response number according to the maximum packet sequence number corresponding to a plurality of consecutive downlink packets, where the plurality of consecutive downlink packets use the target packet as an initial packet. In one embodiment, the target TCP response number includes a next message sequence number of the maximum message sequence number; specifically, the target TCP response number may be the next message sequence number of the maximum message sequence number. It should be noted that, if a message sequence number of a message in the downlink buffer queue is greater than a maximum message sequence number corresponding to a plurality of continuous downlink messages, and the two message sequence numbers are not continuous, the RLC entity determines the target TCP response number according to the maximum message sequence numbers corresponding to the plurality of continuous downlink messages.
For example, in the example shown in fig. 3, if there is no downlink packet with a packet number of 600 and a downlink packet with a packet number of 700 in the downlink buffer queue, the RLC entity may determine the target TCP acknowledgement number according to the packet number of 500. Further, the target TCP response number may be the next message sequence number of message sequence number 500, i.e., target TCP response number 600.
In this embodiment, the target TCP response number is determined according to the maximum message sequence number corresponding to the continuous multiple downlink messages, so that the downlink data transmission rate can be further accelerated while the communication reliability is ensured.
In one embodiment, as shown in fig. 5, the method further comprises:
s250, uploading the uplink message to be transmitted to the PDCP layer under the condition that the uplink message to be transmitted is not a TCP response message.
Specifically, if the uplink message acquired by the RLC entity is not a TCP acknowledgement message, the RLC entity may directly upload the uplink message to be a PDCP layer, so as to accelerate the communication rate.
In one embodiment, as shown in fig. 5, the method further comprises:
s260, if there is no continuous multiple downlink messages taking the target message as the initial message in the downlink buffer queue, uploading the uplink message to be transmitted to the PDCP layer.
Specifically, if the uplink message acquired by the RLC entity is a TCP response message, but there are no continuous multiple downlink messages using the target message as a start message in the downlink buffer queue, the RLC entity may not update the uplink message and upload the uplink message to the PDCP layer.
In one example, as shown in fig. 6, there is provided an RLC layer data transmission method, which specifically includes:
s310, receiving an uplink message to be transmitted on the RLC layer.
S320, judging whether the uplink message to be transmitted is a TCP response message, if so, jumping to step S330, and if not, jumping to step S360.
S330, analyzing the TCP response message to obtain TCP response information. The TCP response message includes an initial TCP response number.
S340, judging whether the downlink message requested by the initial TCP response number continuously exists in the downlink buffer queue corresponding to the RLC layer, if yes, jumping to the step S350, and if not, jumping to the step S360. That is, the RLC entity needs to determine whether there are a plurality of continuous downlink messages using the downlink message matched with the initial TCP response number as the initial message in the downlink buffer queue, and skip to the corresponding step according to the determination result.
S350, modifying the TCP response number of the TCP response message and increasing the advance. Specifically, the RLC entity may increase the TCP response number of the TCP response message from the initial TCP response number to the target TCP response number to implement an advanced response of TCP.
S360, uploading the uplink message to the PDCP layer.
