Abstract

In a packet transmission device and control method thereof which can improve the transmission rate of a packet without adding a high speed user data-conversion card, when packet data is inputted through a single arbitrary channel among a plurality of channels, from among a predetermined number of low speed user data-conversion cards provided common to the plurality of channels, the low speed user data-conversion cards by a number corresponding to a ratio between an output transmission rate of the low speed user data-conversion card and an input transmission rate of the packet data are extracted. The packet data is sequentially and cyclically distributed to the low speed user data-conversion cards extracted. Predetermined length user data outputted from the low speed user data-conversion cards are converted into a frame of HSDPA (High Speed Downlink Packet Access) system and multiplexed into a single channel HS-DSCH (High Speed Downlink Shared Channel) to be outputted.

Description

Technical field [0001] The present invention relates to a packet transmission device and a control method thereof, and more particularly to a packet transmission device and a control method thereof for dividing input packet data into user data of a predetermined length to output it. Background technique [0002] The prior art embodiments [1] and [2] of the packet transmission technology as described above will now be described with reference to FIGS. 16 to 18. [0003] The radio communication system 1 shown in FIG. 16 represents the configuration of a system to which the prior art embodiments [1] and [2] are applied, and the system includes a core network 10 and two radio network control devices 20_1 connected to the core network 10 And 20_2 (hereinafter sometimes denoted as reference number 20), four base stations 30_1 to 30_4 (hereinafter sometimes denoted as reference number 30) managed by the radio network control device 20, and a call connected to the radio network control d...
