SERVICE CONTROL METHOD AND APPARATUS AT ACCESS NODE

Embodiments of the present invention provide a method and an apparatus for service control on an access node, where the access node is divided into at least one access node control protocol ANCP partition, and each ANCP partition corresponds to one network access server NAS. The method includes: obtaining, according to a set rule, a logical identifier of a physical object managed by an ANCP partition, where each logical identifier is used for identifying one physical object, and saving an obtained logical identifier in the ANCP partition; and obtaining, according to the logical identifier in the ANCP partition, an access topology of the physical object managed by the ANCP partition, and reporting the access topology in the ANCP partition to a corresponding NAS, so that the corresponding NAS performs service control according to a reported access topology.
