The present invention relates to a method for accessing integrated services by an access network, including: establishing at least one Multi-Protocol Label Switching (MPLS) Label Switch Path (LSP) in a broadband access network; MPLS encapsulating at a broadband access node a service to be transmitted, and transmitting the encapsulated service in the broadband access network via the LSP. As MPLS is a technology for providing multi-layered connection, in the embodiments of the present invention, MPLS is utilized as the means for networking of broadband access network and private line passing through the core network, so that the problem faced by the broadband access network serving as the bearer network of integrated services can be solved, the integrated services of video, voice, data and private line (including IP private line, and traditional private lines of ATM (Asynchronous Transfer Mode), TDM (Time Division Multiplexing) and FR (Frame Relay)) can be carried over the broadband access network at a lower cost.
