Call-admission controller and method of call-admission control

摘要

A call-admission controller is disclosed that allocates, out of shared resources in a communications system, resources required for communication in multiple calls of different priorities. The controller includes an impact-judging unit configured to make a judgment of, when having detected a low-priority call, the impact of the low priority call on the communications system, and a low-priority call admission-determining unit configured to make, based on the impact of which the judgment is made, a determination of whether to admit the low-priority call.
