Claim Text:
1. A method for transferring signaling based immediate Minimization of Drive Test (MDT) configuration information, applied in an inter-Public Land Mobile Network (PLMN) handover process in a scenario of multiple PLMNs, comprising: during a handover process of a user equipment, a source network device determining whether a target PLMN selected for the user equipment is the same as a PLMN in an MDT-allowable PLMN list of the user equipment; and when the source network device determining that the target PLMN selected for the user equipment is the same as a PLMN in the MDT-allowable PLMN list of the user equipment, the source network device transmitting the immediate MDT configuration information of the user equipment to a target network device; wherein the method further comprising: the source network device selecting the target PLMN for the user equipment, which comprises: after selecting a target cell for the user equipment, the source network device acquiring information about PLMNs to which the target cell belongs, and selecting a PLMN from an intersection between the PLMNs to which the target cell belongs and the equivalent PLMN list allowed by the user equipment as the target PLMN; wherein the information about the PLMNs to which the target cell belongs is configured and issued by a network management background, or is acquired by the source network device interacting with the target network device through an X2 interface message; the equivalent PLMN list is configured and issued by a core network side.
