Call admission control device and call admission control method

摘要

Call admission control is performed by considering whether or not a mobile station that has already performed communications and a mobile station that is newly starting communications can attain respective target transmission data rates. A new call admission judgment unit controls admission of a call from a new mobile station based on a packet allocation frequency for satisfying an existing terminal transmission data rate relating to a plurality of mobile stations and a packet allocation frequency for satisfying a new terminal target transmission data rate relating to a new mobile station. Call admission control can be appropriately performed based on whether or not a target transmission data rate can be satisfied regardless of the cell mode and the way of the occurrence of traffic on a mobile station which has already started communications and a mobile station which is to newly start communications.
