description PROBLEM TO BE SOLVED: To shorten a period during which communication between a terminal and a call control processor is impossible when switching call control processing between processors. SOLUTION: A multiprocessor system is provided with a plurality of call control processors #0-#2 capable of performing the processing of controlling call between terminals 1a-1c, a shared memory 9 to which a plurality of the respective call control processors #0-#2 can access, and a maintenance processor #3 which instructs the start of the control processing of continuing a call to the other call control processor when a trouble is detected in either of the call control processors #0-#2. The other call control processor receiving an instruction from the maintenance processor #3 accesses a region on the shared memory 9 to which the call control processor having the trouble accesses, reads call control data, and reports the change of the call control processor to the terminal of the continuing call.
