METHOD FOR CONTROLLING DYNAMIC COMBINED USE TIMER BASED CALL CONNECTION IN ATM ADAPTIVE LAYER 2

摘要

PURPOSE: A method for controlling a dynamic combined use timer based call connection in an ATM(asynchronous transfer mode) adaptive layer 2 is provided to minimize a consumption of a bandwidth by dynamically controlling a Time_CU value to reduce the time out number and use a remained bandwidth in a traffic for an available bit rate/unspecified bit rat service. CONSTITUTION: When a call is requested(S501), a cell assembly delay time is tested(S503). A Time_CU is increased(S505) and the cell assembly delay time is again tested(S507). The Time_CU is reduced to a previous value(S509) and a call request is received(S511). The Time_CU is compared with a MAX_TCU(S513). When the Time_CU is greater than the MAX_TCU, the call request is received(S511). When the Time_CU is less than the MAX_TCU, steps S505 to S513 are sequentially performed. The Time_CU is reduced(S515) and the cell assembly delay time is again tested(S517). The Time_CU is compared with a MIN_TCU(S519). When the Time_CU is greater than the MIN_TCU, the call request is rejected(S521). When the Time_CU is less than the MIN_TCU, steps S515 to S519 are sequentially performed.
