Provided is a method of resource management and call admission control in an access network in a hierarchical manner.The method of resource management and call admission control in an access network includes: (a) collecting resource information on all of devices constituting the access network and hierarchically constructing the resource information on the access network; (b) when a user requests a connection to the access network, hierarchically extracting position information on the access network from the resource information and connecting the extracted position information to link information in the hierarchically constructed resource information; (c) when a user who succeeds in connecting requests call admission control for an IP communication service, determining an availability of the resources of the hierarchically constructed position information; and (d) when the availability is certified, allocating a band required to the IP communication service to the link information and a part of a margin band of a service class to which the user belongs to respond to the call admission control request.
