Current mobile network architecture is constructed through introducing mobile IP protocol on the basis of IP network. On the one hand it cannot break away from the inherent limitation of IP network, such as no strong security, complex forwarding devices, lack of high expansibility and no QoS guarantee. On the other hand it brings some new problems due to the repair to IP network, such as the triangular routing problem. A new mobile network architecture based on vector network is proposed in this paper. The design philosophy of this architecture is to separate the name address and the switching address of the mobile nodes, so it can support node mobility inherently. Besides, this architecture also possesses many innovation characteristics. For example, soft handoff can be achieved through multi-path connection to improve the handoff performance.
