1. A method for transmitting an inter-system measurement information, comprising:
determining, by a first base station, whether an interface for direct communication exists between the first base station and a second base station according to a pre-configuration information;
determining, by the first base station, a corresponding core network and an interface between the first base station and the corresponding core network according to its own configuration and a type of the second base station under a condition that the interface for the direct communication does not exist between the first base station and the second base station;
sending, by the first base station, a first measurement configuration information to a control plane entity of a first core network through an interface between the first base station and the first core network under a condition that the corresponding core network is the first core network corresponding to the first base station;
sending, by the control plane entity of the first core network, the first measurement configuration information to a control plane entity of a second core network through a first inter core network interaction information by using an interface between the first core network and the second core network corresponding to the second base station, wherein the second base station is registered in the control plane entity of the second core network but not registered in the control plane entity of the first core network;
sending, by the control plane entity of the second core network, the first measurement configuration information to the second base station by using an interface between the second base station and the second core network;
determining, by the second base station, an inter-system measurement configuration information of a terminal in a coverage of the second base station for the first base station according to the first measurement configuration information;
generating, by the second base station, a second measurement configuration information by using interactive request information sent by the first base station;
sending, by the second base station, the second measurement configuration information to the control plane entity of the second core network by using the interface between the second base station and the second core network;
determining, by the control plane entity of the second core network, whether the first base station is registered in the control plane entity of the second core network;
sending, by the control plane entity of the second core network, the second measurement configuration information to the first base station through an interface between the first base station and the second core network under a condition that the first base station is registered in the control plane entity of the second core network; and
determining, by the first base station, an inter-system measurement configuration information of a terminal in the coverage of the first base station for the second base station according to the second measurement configuration information.
