METHOD FOR SUPPORTING LEASED LINE SERVICE OF BROADBAND-WIRE LOCAL LOOP(B-WLL)

摘要

PURPOSE: A method for supporting a leased line service of a broadband-wire local loop(B-WLL), is provided to supply a leased line service through the B-WLL system, by defining a protocol stack and a service scenario for supplying a leased line service. CONSTITUTION: A method for supporting a leased line service of a broadband-wire local loop(B-WLL), performs an initialization step by a media access control(MAC) protocol performing a wireless media control and utilizes allocated wireless resources according to the performance of the initialization step, for bidirectional communication through a leased line between a network and a subscriber. The initialization step comprises the steps as follows. A polling time slot is allocated, and a state of the subscriber is confirmed by the allocation. A MAC session connection is performed between the network and the subscriber, according as the state of the subscriber is confirmed. The wireless resources are allocated to the subscriber, according as the MAC session connection is completed.
