Title: Method of Call Processing in ATM Switching System
Inventor: MUN CHAN
IPC: H04L12/50
Filed: 2001-12-24
Abstract: PURPOSE: A method for processing calls in an ATM(Asynchronous Transfer Mode) switch is provided to prevent an additional incoming call to a corresponding VPCI(Virtual Path Connection Identifier) by transmitting a block message, for blocking the incoming call to the corresponding VPCI, to an object station in the ATM switch when the ATM switch senses that the maximum connection is generated in the corresponding VPCI. CONSTITUTION: If an IAM(Initial Address Message) is received from an outgoing switch, an incoming switch judges whether line information exists in the IAM(S10,S12). If line information exists in the IAM, the incoming switch judges whether it is possible to accommodate an additional connection in a VPCI which belongs in a line(S18). If it is impossible to accommodate the additional connection in the VPCI, the incoming switch transmits a block message with respect to the corresponding VPCI to an outgoing switch, for blocking an incoming call with respect to the corresponding VPCI, and receives a block accept message with respect to the corresponding VPCI from the outgoing switch(S22,S24). The outgoing switch selects a line which belongs in a new VPCI, with respect to an additionally generated outgoing call, and transmits a new IAM to the incoming switch(S26,S28).
