A method is disclosed for providing reliable transmission Quality of Service (QoS) in communication network, in which a QoS connection is established between bearer network resource managers in bearer network control layer, and maintenance management mechanism is well established in terms of the QoS connection. Various QoS resource control messages can be carried through this established QoS connection, so that request of service bandwidth application of the user and the result thereof, as well as the path information allocated by bearer network resource managers can be transferred. The disclosed method is reliable and easy to implement and maintain, with good controlled quality, and can implement resource synchronization between bearer network resource managers. Therefore, implementation of the disclosed method makes it more convenient to manage resources of bearer network uniformly, and provides technical support on guaranteeing transmission reliability of important services.
