The efficient use of the residual bandwidth in the segmentation and recombination (SAR) sublayer of the AAL layer

摘要

In the scheduling table of the sublayer and reassembly (SAR) sublayer of the AAL layer, the present invention comprises a first step (S1) of increasing 1 for a predetermined entry pointer set; A second step S2 of determining whether the current entry specified by the entry pointer of the first step S1 is empty or not and moving to the first step S1 if the entry is empty; A third step S3 of determining whether there is a cell to be sent in the entry if the current entry is not empty as a result of the determination in the second step S2; A fourth step (S4) of outputting the corresponding cell if there is a cell to be transmitted as a result of the determination in the third step (S3); As a result of the determination in the third step S3, if there is no cell to be transmitted, it is determined whether there is no cell to be transmitted in all entries. If the cell does not exist, Step S5; And a sixth step S6 of outputting an empty cell if there is a cell to be transmitted as a result of the determination in the fifth step S5.
