DEVICE OF ATM GATEWAY HAVING MAPPING FUNCTION FOR QUALITY OF SERVICE AND CONTROLLING METHOD THEREOF

摘要

Purpose: there is a device of ATM (asynchronous transfer mode) gateway of the mapping function and its Mitigation options for QoS (service quality) to be arranged to support to receive QoS and be fixed on middle service to being suitble to itself use any type communication network and any kind of Terminal Type by selectable subscriber's network utility of service contact. Construction: when mapping function needs in an ATM gateways, a QoS is compared. The convert function needed at a real service is used for mapping definition by the map operation for executing QoS parameter between the parameter of the service quality based on ATM. The conversion operation for belonging to the service of the ability of the selection navigation content of appropriate services carries out the selection operation of service request from service terminal. When the programing change of the selection of an environment to suitable terminal is performed, transfer/variation operation of routing information will carry out providing the conversion of service display methods and the request of the QoS between appropriate terminal and a server. When service mapping is not requested or restores signal about the one of selected network utility is received, the traffic speed interface function between service terminal and server is performed. QoS appropriate is met according to the one of traffic priority control operation in order to request the traffic of specific QoS to be controlled. It is performed when restoring to complete the media formats change by transmission form terminal, between service terminal and server in the server of service or stop signal.
