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 invention relates to the communication field, and discloses a data delivery method and device, which can reduce the influence of sequential delivery on the download rate of the terminal; in addition, can prevent the upper layer from disconnecting the link because the data packet cannot be received for a long time. The method includes: processing the unprocessed SDU, when the SDU is a TCP packet, judging whether there is a continuous TCP message in the socket to which the SDU belongs; if there is a continuous TCP message, the continuous TCP message is Document submission; if there is no continuous TCP message, continue to process the unprocessed complete SDU, if the continuous TCP message of the socket is obtained within the preset time, the continuous TCP message will be reassembled Submit; if the continuous TCP packets of the socket are not obtained within the preset time, the obtained TCP packets in the socket will be reassembled and delivered after the preset time is reached.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for data submission. 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, 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) protocol. The structure of the HSDPA protocol is divided into five layers, 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 LinkControl, radio link control) layer, MAC-hs (Medium Access Control High Speed,...
