Summary:The invention relates to an optimal switching method supporting multiple PDN (Packet Data Network) connections, a network node and an optimal switching system supporting multiple PDN connections. In the optimal switching process in an activated state of UE (User Equipment) from an LTE (Long Term Evolution) network to an eHRPD (evolved High Rate Packet Data) network, an MME (Mobility Management Entity) acquires information of each PDN connection established by the UE, and the information of each PDN connection comprises unique identification information of each PDN connection and a corresponding GRE (Generic Routing Encapsulation) KEY; the information of each PDN connection is sent to an HSGW (HRPD Serving Gateway) by an eAN/ePCF (evolved Access Network/evolved Packet Control Function); the HSGW receives the unique identification information of each PDN connection established by the UE and the corresponding GRE KEY; and according to the unique identification information of each PDN connection, the correspondin
