Claim Text:
1. A method for service control on an access node, wherein the access node is divided into at least one access node control protocol (ANCP) partition, each ANCP partition managing a physical object, and each ANCP partition corresponding to at least one network access server (NAS), the method comprising: constructing an ANCP message comprising an access topology of the physical object; and reporting the access topology of the physical object to at least one corresponding NAS, wherein the access topology is carried on a circuit identifier (CID) field of the ANCP message, the CID field comprises an identifier of the access node and a logical identifier of the physical object, the physical object is a physical port or a permanent virtual circuit (PVC), the logical identifier is a slot number, frame number, port number, virtual channel identifier (VCI) or virtual path identifier (VPI), wherein when an activation mode between the access node and a user terminal is an asynchronous transfer mode (ATM), the ANCP message is based on an ATM format and when the activation mode between the access node and the user terminal is a packet transfer mode (PTM) the ANCP message is based on an Ethernet (ETH) format.
