Abstract

The present invention provides a method and device for forwarding mobile IPv4 data in communication network access equipment and a corresponding access communication network system. The system includes mobile nodes, network access equipment, and some or all of them with external agent functions. Several edge routers, wherein the network access device listens to the mobile IPv4 control message between the mobile node and the edge router, analyzes the control message, establishes a corresponding data forwarding table, and uploads the , The downlink mobile IP data packet is forwarded to the corresponding edge router or mobile node. The invention effectively solves the problem of supporting mobile IPv4 in the existing access network system.
