摘要:
A method and apparatus is provided for transmitting data in a broadband wireless access communication system. If transmission data is generated, a data packet generator sets information corresponding to a service type of the generated data in a predetermined field of the generated data. A data packet parser parses the set information, and quality-of-service determiner determines a quality-of-service of the data set in the predetermined field according to the parsing result. A data mapper maps the data to transmission traffic according to the determined quality-of-service before transmission.

A transmission delay caused by a Bandwidth Request (BR) of a Mobile Station (MS) in a broadband wireless communication system can be avoided. An operation of the MS includes performing an initial BR to allocate resources across a plurality of frames. When a resource is allocated according to the initial BR, an adaptive BR is performed on the resource in a piggyback manner by using the resource while transmitting an acknowledge (ACK) message corresponding downlink Transmission Control Protocol (TCP) data.

The present invention relates to an accounting information processing method using a wireless communication network, and in particular to an accounting information process method using a wired communication network which is capable of classifying an accounting information input work into a work which may need an accounting knowledge and a work which may be performed without an accounting knowledge and is capable of implementing an accounting information generation work based on the internet by a plurality of part time workers who do not have an accounting knowledge with respect to an accounting information input work or who are capable of performing an accounting work at home.
摘要:
Disclosed herein is a method of discriminating a through-wall crack and measuring the through-wall length of the crack in a steam generator tube of a nuclear power plant. The method of the present invention is characterized in that the through-wall crack is discriminated and the through-wall length of the crack is measured in such a way that there are measured the number and positions of inflection points of a graph that is plotted by relating characteristic amplitude values of eddy current signals, which are generated whenever a coil of a motorized rotating probe passes the crack while being spirally rotated, to the positions in the length of the crack.
