Distributed user access system and method

The invention discloses a distributed user access system and a distributed user access method. The system is positioned between a core network and a service network and comprises flow dividing equipment, and a plurality of user access gateways arranged in a distributed manner, wherein the flow dividing equipment is connected with the core network and is used for collecting data packets transmitted by a user terminal and redirecting the data packets to the corresponding access gateways according to the protocol types and preset forwarding policies of the data packets; and the plurality of useraccess gateways are connected with the flow dividing equipment and a corresponding service server, serve as epoxy nodes to initiate service requests corresponding to the data packets to the service server, and transmit service responses fed back to a user terminal through the flow dividing equipment and the core network. In the distributed user access system and the distributed user access method, which are disclosed by the embodiment of the invention, the functional entities are distributed separately and a uniform coordinated scheduling mechanism of the functional entities is established, so the flexible arrangement of a distributed user access mode is realized and the service expansion and post management and maintenance are facilitated.
