Abstract:
The present invention provide a network system and a network communication method. By this invention, a cache server or an application server is moved from an IDC equipment room in a metropolitan area network to a local radio access network or an IP transport network between the radio access network and a wireless core network, and an edge node is deployed to steer a TCP packet for a central server to the cache server or the application server, to implement traffic scheduling. In this way, a transmission delay from the radio access network to a packet core network is reduced, thereby improving user experience.

Claim (Index 6):
The network system according  claim 3 , wherein, when the terminal device is handed over from a first base station cell that comprises the edge node to a second base station cell,\n the central node is further configured to:\n replicate and encapsulate an uplink TCP packet sent by the terminal device; and \n forward a replicated and encapsulated uplink TCP packet to the edge node, wherein the edge node is configured to determine whether the terminal device has already been handed over from the first base station cell to the second base station cell; \n the edge node is further configured to:\n after decapsulating the replicated and encapsulated uplink TCP packet:\n perform DNAT on the uplink TCP packet according to the IP address that needs to be steered; and \n forward a translated uplink TCP packet to the third-party server; and \n \n after performing source network address translation (SNAT) on a downlink TCP packet received from the third-party server; replicate and encapsulate a translated downlink TCP packet; and forward a replicated and encapsulated downlink TCP packet to the central node; and the central node is further configured to:\n after decapsulating the replicated and encapsulated downlink TCP packet, forward a decapsulated downlink TCP packet to the terminal device.
