摘要
A communication network architecture including a broadband radio access network is provided. The architecture includes a terminal for transmitting an application layer service request message to request a service, a Policy Charging Rule Function (PCRF) for generating Quality of Service (QoS) parameters of an Internet Protocol (IP) layer using QoS parameters of an application layer contained in the application layer service request message, a first Policy Decision Function (PDF) for generating one or more QoS parameters of the IP layer in addition to the IP layer QoS parameters generated at the PCRF and a second PDF for generating a QoS parameter set of a radio access network using the IP layer QoS parameters generated at the PCRF and the one or more IP layer QoS parameters generated at the first PDF. The communication network guarantees an end-to-end QoS.
