Rufzugangskontrollverfahren und Kommunikationssystem in dem das Verfahren angewandt wird

Each communication is classified into any one of a plurality of communication types in advance. A plurality of threshold values used for determining whether or not the resources are to be allocated are set up in advance. The plurality of threshold values differ from each other according to the communication types and a predetermined number of divided traffic amount ranges such that a difference in ease of resource allocation between the communication types increases as a traffic value increases. When a communication connection request is made (S7), the traffic of communication being executed is measured (S8, S9). A threshold value is selected according to the communication type of a communication associated with the connection request and the measured traffic (S10, S11, S15). Whether or not resources may be allocated to the communication associated with the connection request is determined based on the selected threshold value and the measured traffic (S12, S16).
