MEASUREMENT-BASED CONNECTION ADMISSION CONTROL IN PACKET-BASED MOBILE SERVICE NETWORKS

摘要

A method for processing connection requests for guaranteed bit rate connections in a transport network section of a mobile service network, wherein with a connection request for a guaranteed bit rate connection a required bandwidth and a quality class identifier value are specified on the air interface comprises mapping the quality class identifier value of the connection specified on the air interface to a service class identifier value used in the transport network section; determining a value representing an initial estimate of the respective connection bandwidth required in the transport network section using at least one of the required bandwidth specified for the connection on the air interface and its respective quality class identifier value; determining in the transport network section at least one value representing a traffic load corresponding to guaranteed bit rate connections carried on the transport network section; and deciding about acceptance or rejection of the connection request using the service class identifier value, the value representing an initial estimate of the respective connection bandwidth required in the transport network section, and at least one of the at least one values representing a traffic load corresponding to guaranteed bit rate connections carried on the transport network section.
