Provided are node authentication and node operation methods within service and access networks for bundle authentication between the service and access networks in a next generation network (NGN). A method of authentication processing of a node (S-CSC-FE/I-CSC-FE (Serving Call Session Control Functional Entity/Interrogating Call Session Control Functional Entity)) within a service network for bundle authentication between service and access networks, the method including: receiving first authentication information about access authentication of a terminal from a first node within the service networks; requesting to receive second authentication information from a second node within the service network based on the first authentication information; and comparing the first authentication information with the second authentication information to authenticate the terminal.

Node authentication and node operation methods within service and access networks in NGN environment

Provided is a method for forming a customized-quality integrated transport network based on synch and asynch frames, and a transport network forming apparatus thereof. The method of the present invention includes: a) synchronizing a transmission bit rate in a network; b) when the transmission bit rate is synchronized in the network and a connection request is received, establishing a connection by determining a route and a start cycle time of the link based on a quality of the connection request and transporting it to nodes of the link; and c) transmitting data to be transported to a link of an adjacent node within the virtual cycle time when the data are synch frames; or when the data are asynch frames and the data are not transmitted within a virtual cycle time of a link to be switched, keeping the data waiting for a next cycle time.
