Method for implementing integrated network subnet movement

TL;DR: In this paper, a method for implementing integrated network subnet movement is proposed, which comprises the following steps of: 1) detecting mobility, namely sending access request message to an access switching router and executing the following three steps 2) and 3) if a mobile router detects that the subnet moves to a new network, otherwise, sending response message to the access switch router; 2) informing a mapping server of a new mapping relationship, namely distributing the mapping relationship to terminals in the sub-net and informing the mapping servers of updating the mapping table by the access switching routers;

Abstract: The invention discloses a method for implementing integrated network subnet movement. The method comprises the following steps of: 1) detecting mobility, namely sending access request message to an access switching router and executing the following steps 2) and 3) if a mobile router detects that the subnet moves to a new network, otherwise, sending response message to the access switching router; 2) informing a mapping server of a new mapping relationship, namely distributing the mapping relationship to terminals in the subnet and informing the mapping server of updating the mapping table by the access switching router; and 3) updating the mapping relationship on the access switching router, namely deleting the old mapping relationship on an access switcher, increasing the mapping relationship of a communication opposite terminal node on the access switching router and updating the mapping relationship of terminals in a mobile network on a communication opposite terminal access switching router. The method can realize routing optimization and effectively support the movement of the subnet, and the terminals in the subnet do not know the position of core network equipment, so the security of the core network can be protected.
