TRANSFER OF INFORMATION IN A COMMUNICATION NETWORK WITH A VERIFIED QOS

摘要

In a communication network comprising a call control level (CCL), a resource control level (RCL) and at least one endpoint (A) for an information transfer, a request (RQ) for a QoS determination for an information transfer is only fully verified in the call control level (CCL). An encoded token (T) is formed therefrom in the connection and transmitted to the resource control level (RCL) by the endpoint (A). A request (RQ) for QoS coming from the endpoint (A) is then merely determined by means of the encoded token (T). When successful, the communication network is configured such that the information is transmitted with the QoS as determined according to the invention. The invention permits an efficient, secure and accurate provision of QoS in integrated speech and data networks. Extensive modifications to existing routers in the resource control level (RCL) are particularly avoided. On regularly repeated transmission of the token (T), a consistent provision of the available QoS and a secure and accurate charging for the information transfer are supported.
