Abstract
In a communication network, which includes a call control level CCL, a resource control level RCL and at least one terminal A assigned to data transfer, a QoS requirement RQ determined for a data transfer is verified at expense at call control level CCL. An encrypted token T is then created from this and transferred via terminal A to resource control level RCL. This latter verifies an incoming QoS requirement RQ from terminal A only by means of the encrypted token T. If successful, the communication network is configured so that the data is transferred with the QoS verified according to the invention. The invention allows the efficient, secure and correct provision of QoS in integrated voice and data networks. In particular extensive modifications to existing routers are avoided at resource control level RCL. The regularly repeated transfer of tokens T also supports consistent termination of the QoS provided and secure and correct billing of the data transfer.
