Abstract: A method and system for realizing service reallocation of core network are provided. The method includes the following steps. A load shunting flag and a shunting proportion corresponding to a core network node are configured in a radio network controller (RNC). When the RNC receives a message of a user and determines that the service requested by the user is a registration service, the core network node corresponding to the registration service is acquired. If the core network node has no load shunting flag, the core network node is selected. If the core network node has the load shunting flag, a load shunting is performed according to the configured shunting proportion of the core network. All the scenes that need the load reallocation can be realized simply and expediently by utilizing the method.
