Asynchronous transfer mode (ATM) multiplexing process device and method of the broadband integrated service digital network subscriber access apparatus

Claim 1

An ATM multiplexing process device of a broadband integrated service digital network subscriber apparatus, comprising: (a) input buffering means for storing cells inputting each input terminal through a plurality of input lines momentarily; (b) cell identification means for classifying input cell data to a predetermined quality of service (QOS) class in accordance with connection establishment information, QOS class information and a header information of the input cell data after receiving the input cell data from said input buffering means, and outputting ATM cell data and input traffic information; (c) QOS class buffering means for storing the ATM cell data input from said cell identification means, respectively, according to the class, and for outputting buffer stage information; (d) scheduling control means for outputting the connection establishment information and QOS class information to said cell identification means, and for outputting all operation information of the ATM multiplexing process device and input traffic information, after receiving the input traffic information from said cell identification means, the buffer state information from said QOS class buffering means, and a QOS parameter; (e) scheduling means for outputting the cells input from said QOS class buffering means to the outside in accordance with scheduling order information input from said scheduling control means; and (f) connection state management means for outputting the QOS parameter to said scheduling control means in accordance with an added value of a network operator to provide network resources efficiently and equally to manage connection state information with the network, and for transferring all the operation information of the ATM multiplexing process device and the input traffic information to the network operator after receiving them from said scheduling control means.

Claim 4

A method for processing an ATM multiplexing of a broadband integrated service digital network subscriber access apparatus, comprising the steps of: (a) classifying cells to be transmitted according to a QOS class and storing the cells; and determining whether there is a full QOS class buffer; (b) outputting the cells in a buffer of the first priority according to the FIFO principle until the number of served cells becomes the same as a threshold value after making a filled buffer, if any, the buffer of the first priority by granting priority to the QOS class buffer; and outputting all cells in a buffer of subsequent priority according to the FIFO principle for all buffers sequentially if there is a cell; and (c) outputting all of the cells in a predetermined buffer of the first priority according to the FIFO principle if there is no filled QOS class buffer; outputting all cells in the QOS class buffer of the subsequent priority according to the FIFO principle sequentially; and outputting all cells for all QOS class buffers.

Claim 5

A method for processing an ATM multiplexing of a broadband integrated service digital network subscriber access apparatus, comprising the steps of: (a) classifying cells to be transmitted according to a QOS class and storing the cells; and determining whether there is a full QOS class buffer; (b) outputting the cells in a buffer of the first priority according to the FIFO principle until the number of served cells becomes the same as a threshold value after making a filled buffer, if any, the buffer of the first priority by granting priority to the QOS class buffer; and outputting all cells in a buffer of subsequent priority according to the FIFO principle for all buffers sequentially if there is a cell; and (c) outputting all of the cells in a predetermined buffer of the first priority according to the FIFO principle if there is no filled QOS class buffer; outputting all cells in the QOS class buffer of the subsequent priority according to the FIFO principle sequentially; and outputting all cells for all QOS class buffers.
