METHOD AND ARRANGEMENT FOR CHECKING WHETHER THE USE OF A SERVICE IS PERMISSIBLE

摘要

The invention relates to an access control function (ZF) which checks a requested use (NU) of a service (DI) by considering an available capacity CV which is detected by considering the entire transmission capacity (G) and is available to an access node (ZK) for transmitting traffic flows (VS) to the communications network. Said service is carried out in at least one communications network (KN) that is provided with an entire transmission capacity (G). Said access node (ZK) is allocated to the access control function (ZF) which checks whether said requested use (NU) of the service (DI).
