Problems solved by technology

However, when there are multiple TCP sockets for concurrent transmission of data and there is a loss of PDU, the data on the remaining sockets can continue to be transmitted only after the PDU is successfully retransmitted, which will increase the transmission delay on all sockets , resulting in a decrease in the rate at which the server sends data
Therefore, when the RLC layer on the network side sets in-order delivery to false (no), the user uses in-order delivery or out-of-order delivery, which cannot guarantee high-speed data transmission in the network when the number of concurrent TCP sockets is different.

Abstract

The present invention relates to the field of communication and discloses a data submitting method and device. The present invention can reduce the influence of adopting in-sequence submission on the download rate of a terminal and additionally, can prevent an uplink from being disconnected because a data packet cannot be received for long. The method comprises: processing an unprocessed SDU (Service Data Unit); when the SDU is a TCP (Transmission Control Protocol) packet, judging whether continuous TCP messages exist in a socket to which the SDU belongs or not; if the continuous TCP messages exist, submitting the continuous TCP messages; if the continuous TCP messages do not exist, continuing to process the unprocessed complete SDU; if the continuous TCP messages of the socket are obtained within preset time, submitting the continuous TCP messages after the continuous TCP messages are recombined; and if the continuous TCP messages of the socket are not obtained within the preset time, submitting the obtained TCP packet in the socket after the obtained TCP packet is recombined when the preset time is reached.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a data submission method and device. Background technique [0002] 3G (3rd-Generation, third-generation mobile communication technology) refers to cellular mobile communication technology that can support high-speed data transmission. In the mobile Internet, the downlink refers to the mobile Internet side to the user side. In the 3G-based mobile Internet, users can enjoy high-speed downlink services. [0003] The mobile Internet runs the HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) protocol. The structure of the HSDPA protocol is divided into five layers, which are in order from top to bottom: application layer TCP (Transmission Control Protocol, Transmission Control Protocol) / IP (Internet Protocol, Internet Protocol), PDCP (Packet Data Convergence Protocol, Packet data convergence protocol) layer, RLC (Radio Link Control, radio link co...
