PURPOSE:To improve the information transfer efficiency of a system on the whole by modifying the assignment by monitoring in-use states of resources assigned to calls and then by modifying the information transfer efficiency on the basis of the modification of the assignment. CONSTITUTION:In response to request (2) for buffer assignment modification from call processing circuit 5, buffer control circuit 13 controlling the assignment of buffer memories 9-12 to all communication circuits 1-4 monitors in-use states of buffer memories 9-12 having been assigned to respective communication circuits 1-4 and then modifies the assignment of buffer memories 9 and 10 between communication circuit 2, having empty buffer 102 satisfying the request requirements, and communication circuit 1 generating request. Then, relative call processing circuit 6 checks efficiency in information transfer again on the basis of a newly assigned buffer memory and, upon occasion, sends modification request control signal (5), so that the information transfer can be performed with assigned efficiency in response to new emergency call (1). |
