Method for realinzing ATM signaling of Neywork Interface Equipment in LMDS System

摘要

Local Multipoint Distribution Service (hereinafter referred to as LMDS) system, especially in LMDS system where LMDS system performs ATM signal processing effectively in order to reduce load of headend device in LMDS system. The present invention relates to a method for implementing ATM signal processing of a device, and includes a protocol for wireless media control (MAC), a protocol for defining an interface between a user and a network, and a network interface. In a network access device having a MAC control unit capable of controlling a subscriber modem and having an allocation function for the ATM signal processing and a radio channel area setting function between the subscriber and the headend device and a database for the subscriber, Directly requesting channel allocation from a network access device; Verifying authentication of one subscriber modem; if the network access device confirms whether the subscriber modem is authenticated, assigning a channel to the corresponding subscriber modem by the MAC control unit; and the plurality of subscriber modems and the network. ATM data is transmitted through a channel allocated by the signal processing procedure between access devices.
