Abstract

PURPOSE:To improve the processing capability of a decentralized control processing packet exchange with a few memory capacities by decentralizing a call setting processing function and a packet protocol processing function to plural processors. CONSTITUTION:A terminal device 301 connected to a packet protocol processing processor 401 through a line 100 is used as a calling terminal device and a terminal device 302 connected to a packet protocol processing processor 402 through a line 400 is used as an incoming terminal device. The packet protocol processing processor 401 receiving a call setting request packet from the calling terminal device 301 selects a call setting processing processor 501 among call setting processing processors 501-503 and transmits a call setting request signal corresponding to the call setting packet. Thus, the processor 501 uses a calling and a called terminal address of the call setting request signal to recognize a call from the terminal device 301 to the terminal device 302, selects the packet protocol processing processor 402 accommodating the incoming terminal device 302 and transmits an incoming notice signal.

ある。(Structure of the Invention) In order to achieve the above object, the distributed control processing packet switching system according to the present invention comprises a packet switching equipment including a packet protocol processing processor and a call setup processing processor, and the packet protocol processing processor receives a call setup request packet from a terminal. When the call setup processor receives the call setup processor, it selects one of the call setup processors and sends a call setup request signal, and that call setup processor recognizes the calling terminal and the called terminal from the call setup request signal, and sends the call setup request signal to the call setup processor. A packet protocol processing processor to accommodate is selected and an incoming call notification signal is sent, and the packet protocol processing processor to which the incoming call notification signal has been sent processes the calling terminal and the packet protocol that received the call setup request packet from the calling terminal. Recognizing that the call is via the processing processor, it sends an incoming call notification signal to the called terminal and also sends a line selection completion notification to the call setting processor, which then converts this signal into a call setting request packet. The received packet is transferred to a protocol processing processor and the call setup process is completed.
