Access network element, access network system and access method

The invention discloses an access network element, an access network system and an access method and aims to solve the problems of complicated system architecture of a long-term evolved (LTE) home NodeB, high overhead and long delay time. The access network element has integrated functions of a serving gateway and a packet data gateway or integrated functions of the serving gateway, the packet data gateway and a mobility management entity, and an interactive interface between the integrated access network element and a core network, an interactive interface between the access network elements and an interactive flow are provided. By adoption of the technical scheme provided by the invention, the system architecture of an LTE home access network can be simplified, overhead is reduced, and delay time is shortened.
