Abstract
Disclosed are a handoff system and a method among heterogeneous networks. The handoff system among heterogeneous networks has plural access nodes which supports wireless communication with a mobile terminal; and a crossover node which selects resources of an access node to which a handoff is made without repetitive communications between access modes and the mobile terminal in selecting an access node. The handoff system performs a handoff to a network if resources of the network are sufficient for wireless communication.
