Background

The transmission Control/Internet Protocol (TCP/IP) reference model is an abstract layered model in which all TCP/IP-based network protocols are categorized into 4 abstract "layers". Each layer is built on the services provided by the first layer, providing services to the higher layers. As shown in FIG. 1, the TCP protocol resides at the transport layer of the TCP/IP reference model.

Both communication parties using TCP for data communication need to establish TCP connection before service data transmission, specifically, the process of establishing TCP connection includes 3 times of message interaction, as shown in fig. 2, including the following steps:

step 1: a user terminal sends a Synchronization (SYN) message to a server;

step 2: the server responds to the SYN + ACK message to the user terminal;

and step 3: the user terminal responds to the server with an Acknowledgement (ACK) message;

the three-time message interaction is three-time handshake of TCP connection, after the handshake is successful, the base station is used as an intermediate network element of the user terminal and the server, corresponding connection resources are distributed for the user terminal, and the user terminal and the server can start service data transmission.

Compared with a 4G network, the requirement of a 5G network for delay and throughput is higher, and for the low-delay and high-throughput characteristics of the 5G network, the prior art discloses a scheduling method for evolving to a 5G low-delay, including: receiving newly transmitted data at a current subframe, generating a pre-scheduling user queue, and synchronously receiving retransmission service and/or emergency service data; adjusting pre-scheduling users in the scheduling queue, and inserting emergency service users and retransmission service users into the pre-scheduling user queue; multiplexing and packaging the sending user, and sending the multiplexing and packaging to a baseband; and returning the user queue of the unsuccessfully transmitted retransmission failure user/new data, wherein the user of unsuccessfully transmitted emergency service generates a preemption queue return. Or the congestion data is judged according to the priority, so that the low-delay high-throughput characteristic of a 5G network is met, for example, a congestion data priority judging method for a 4G/5G high-speed network is disclosed, an upper computer obtains the maximum transmission efficiency and the packet header delay according to a Channel Quality Indicator (CQI) fed back by user equipment, and a weighting coefficient is obtained through calculation; setting the queue length and the window size of a Transmission Control Protocol (TCP) according to 4G/5G network transmission; the upper computer obtains the current transmission rate through the feedback data of the user equipment; obtaining throughput according to the window size of the TCP; establishing a scheduling model according to the length queue, the current transmission rate and the throughput of the TCP; and calculating the priority weight according to the scheduling model and the weighting coefficient, and judging the priority according to the priority weight, wherein the user with high priority weight has high priority, and the user with high priority preferentially distributes resource blocks.

However, in the present day of the rapid development of the mobile internet, a large number of connections are based on the TCP, the handshake delay of the TCP connection will result in the increase of the delay of the 5G network, and how to increase the transmission rate of the TCP connection and reduce the link delay becomes a difficulty.

and if the current handshake stage of the terminal and the server is judged to be the completion of TCP connection, allocating a second uplink resource to the terminal which completes the TCP connection.

Specifically, the method can be applied to, for example, a 4G communication system, a 5G communication system, and other such communication systems; the first device of the execution main body can be a base station, such as an eNB, a gNB and the like; the terminal is alternatively referred to as user equipment, and may be, but is not limited to, various mobile phones, smart terminals, multimedia devices, streaming media devices, and the like; when a terminal and a server need to establish TCP/IP connection, the terminal and the server communicate by mutually sending data packets carrying handshake signals so as to establish the TCP/IP connection; the method comprises the steps that a terminal sends an uplink data packet to a server through a base station, the uplink data packet comprises connection request information and connection confirmation information such as SYN request and ACK response, after the server receives the uplink data packet of the terminal, a downlink data packet is replied to the terminal through the base station, and the downlink data packet comprises reply confirmation information of the request information of the server to the terminal, such as SYN + ACK response; the base station judges the current handshake stage of the terminal and the server according to the received uplink data packet and the downlink data packet, if the uplink data packet comprises connection request information, the base station can judge that the current handshake stage of the terminal and the server is the first handshake, if the downlink data packet comprises reply confirmation information, the base station can judge that the current handshake stage of the terminal and the server is the second handshake, and if the uplink data packet comprises connection confirmation information, the base station can judge that the current handshake stage of the terminal and the server is the third handshake, namely TCP connection is completed.

When uplink data needs to be transmitted by the terminal, the terminal needs to Request allocation of uplink resources to the base station when the terminal and the server complete the second handshake, that is, an uplink Scheduling Request (SR) and a brs (buffer Status report) are reported to the base station, however, a time delay is introduced by the SR and BSR mechanisms, and thus the efficiency of TCP connection is reduced. Therefore, in order to reduce the time delay introduced by the report of SR in the third step of the TCP connection handshake phase, when the base station determines that the current handshake phase between the terminal and the server is the second handshake, the base station allocates a first uplink resource to the terminal that completes the second handshake according to a preset resource size, specifically, the preset resource size may be, but is not limited to, 10bytes or 15 bytes; in order to reduce the end-to-end time delay of TCP connection, the base station determines that the TCP connection is completed in the current handshake stage of the terminal and the server when the third handshake is completed, and second uplink resources are distributed to the terminal which completes the TCP connection.

wherein B represents the uplink resource size, Period_cRepresenting a preset statistical period, S representing the transmission rate of the downlink data packet in the preset statistical period, A₁Represents the average size of the downlink data packet in the preset statistical period, A₂And Q represents a correction factor.

Specifically, the correction factor Q may be set by itself, or may be determined according to how many downlink data packets are averagely acknowledged by one ACK data packet sent by the terminal.

The specific implementation process may be that, when the base station determines that the current handshake stage of the terminal and the server is to complete TCP connection, the base station counts the received uplink data packets within 1000ms according to a preset counting period of 1000ms and calculates the average size a of the uplink data packets₁Counting the received downlink data packets within 1000ms and calculating the average size A thereof₂And calculating the transmission rate S of the downlink data packets within 1000ms, determining a correction factor Q according to the average number of downlink data packets confirmed by one ACK data packet within the statistical period of 1000ms, and finally calculating according to a formula (2) to obtain the size of the uplink resource.
