Embodiments of the present invention relate to the communications field and provide an access control apparatus, system and method. The apparatus comprises: a receiver, a processor and a transmitter. The method comprises: receiving a first service chain forwarding rule sent by a controller; receiving a first packet sent by a classifier; and when a service chain identifier carried in the first packet matches a first service chain identifier in the first service chain forwarding rule, forwarding the first packet to a first access network element according to the first identifier. The present invention achieves control over an access network element based on an SDN mechanism; and moreover, a control plane can achieve forwarding control over an access network and a service processing network based on a unified forwarding control mode, thereby achieving service chain-based SDN access management and mobility management in a mobile network. |
