摘要： A communication scheme for improving the performance of communications utilizing the transport layer connection provided via a radio network, by enabling a control of the transport layer connection according to the radio communication state and property of the radio terminal, without changing implementation of the transport layer of a terminal connected to a wire network. The gateway device is provided with a control unit for controlling a connection in the radio transport layer protocol according an information regarding a radio communication state of the radio terminal device, where the information regarding the radio communication state of the radio terminal device is notified from either a radio base station device covering a radio service area in which the radio terminal device is located or a home location register for carrying out at least registration and management of the radio terminal device.

摘要： A scheme for error control on AAL in ATM networks capable of realizing a reliable communication with a high throughput and a low latency. On AAL, the segmented data are sequentially written into each column of a matrix shaped data region in an interleaver, while variably setting a last column of the data region in the interleaver. Then, an error control code for the data up to the last column in each row of the data region in the interleaver is obtained and written into a corresponding location within a matrix shaped error control code region in the interleaver. The contents of each column of the data region and the error control code region in the interleaver are then read out, and a prescribed header/trailer is attached to a prescribed number of columns of the data and/or the error control codes read out from the interleaver to form a data unit. Each data unit is sequentially given to a lower layer such that data units are transmitted in forms of ATM cells through the ATM network and an error correction using the error control codes can be carried out for the data at a receiving side when an error occurs during data transfer.
