ABSTRACT:
A method of assigning a connection identifier for an asynchronous transfer mode switching system, includes the steps of: (a) analyzing a parameter transmitted in a VPI allocation request if it is received, analyzing the number of connections and the number of VPI used in SIM, and confirming whether a VPI desired to be used in VPI allocation request if the input parameter is normal and connection is available; (b) changing the usage state of VPI assigned to a VPI management table if the VPI is designated and this is in no use, increasing the number of VPI and the number of VPI assigned in the connection identifier management table, indicating a VPI assigned, or selecting a VPI in no use in SIM if the VPI is not designated with reference to the VPI management table, and changing the usage state of the VPI assigned in the VPI management table.
