8. A method of call-admission control which allocates out of shared resources in a communications system resources required for communication in a plurality of calls of different priorities, comprising the steps of:
-
judging, when having detected a low-priority call, an impact of said low-priority call on the communications system;
determining, when judged that said impact is large, a low-priority call-admission threshold value so that the ease of allocation of said low-priority call is set to be lower than the ease of the allocation of a high-priority call; and
determining, according to said determined call-admission threshold value, whether to admit said low-priority call.
