<p>PURPOSE:To suppress the increase of the number of states due to the increase of the number of connections and at the same time to make all connections select the same route (VPI). CONSTITUTION:A task starting part 31 receives the signals (call and connection control signals) from a signal control part 21 for generation of a call and generates a call control task 32a in response to the call to start the task. At the same time, the part 31 generates the connection control tasks 33a1-33am in response to the connections and starts these tasks. The task 32a performs the call control processing for the control of an entire call, like the charging control, the selection control of the same route for each connection, etc., based on the originating number and called number included in the call control signal. Meanwhile each of tasks 33a1-33am sets up and releases the path of each connection by the instruction of the task 32a.</p> |
