Problems solved by technology

[0011] In such a mobile communication network of the prior art, when the mobile communication terminal deviates from the communication pollution area where handover is performed, packets that have no influence on the transmission speed are sent to the mobile communication terminal, causing consumption of the wireless channel, and mobile communication Decrease in the actual transmission speed of the terminal

Embodiment Construction

[0029] A preferred embodiment of the invention shown in the drawings will now be described in detail.

[0030] The present invention can be embodied as a mobile communication terminal capable of performing TCP data communication. However, the present invention can be additionally applied to wireless communication systems operating according to other specifications.

[0031] In the present invention, when an error occurs during packet transmission between a mobile communication terminal and a server, TCP flow is appropriately controlled by employing a mobile congestion avoidance scheme, resulting in preventing consumption of wireless resources and improving transmission speed when handover is performed. Therefore, the present invention focuses on the fact that a mobile TCP packet can be identified using the mobile option field of the TCP packet.

[0032] Fig. 4 is an exemplary diagram of a TCP connection in the present invention. As shown in the figure, the TCP of the server ...

Abstract

Provides data transmission in mobile communication networks, and more specifically, a TCP flow control method for data transmission in high-speed mobile communication networks performing manual short-circuit / handover, which focuses on the following aspects, using mobile options of TCP packets The field identifies a mobile TCP packet, and the method includes determining which of a wired or mobile communication terminal is connected to the server, and controlling the transmission speed using different congestion avoidance schemes according to the determination.

Description

technical field [0001] The present invention relates to TCP (Transmission Control Protocol) data transmission in a mobile communication network, and in particular to a TCP flow control method for data transmission in a high-speed mobile communication network performing manual short circuit / handover. Background technique [0002] TCP (Transmission Control Protocol) is used together with IP (Internet Protocol) to transfer message-type data between computers on the Internet. While IP basically controls data transfers, TCP queries and manages data packets. [0003] A connection method of such a TCP communication network will be described below. Wired communication terminal users such as PCs (Personal Computers) typically use SLIP (Serial Protocol) or PPP (Point-to-Point Protocol) to connect to the Internet. Instead, the mobile communication terminal communicates with the server using PPP provided by the mobile communication network. Also, considering the characteristics of th...
