Abstract: The disclosure discloses a method and an apparatus for transforming a working mode in a Cognitive Radio (CR) system, which are used for solving the technical problem that a subsystem maliciously occupies the spectrum resources which are temporarily unused by other system in a system adopting a CR technology. In the disclosure, a network side measures the demand degree of each cell on borrowed spectrum and sets a conditions of enabling and disabling the CR working mode to determine whether to perform working mode transformation on the cell and specify a network allocation method for a mobile terminal in a corresponding working mode, so as to coordinate the allocation of the spectrum resources, and avoid the abuse of the borrowed spectrum resources; the CR working mode of the cell with low demand degree is disabled by the network side; the borrowed spectrum resources of the cell are released; and therefore, more borrowed spectrum resources are available to the other cells having a higher demand degree on the borrowed spectrum, and the overall performance of the system is improved.

Abstract: The disclosure discloses a method for handover based on a radio resource allocation database. The method includes that the radio resource allocation database is constructed and dynamically maintained; after receiving a handover request from a User Equipment (UE), a Base Station (BS) determines in the database a Radio Access Technology (RAT) and the corresponding carrier frequency resources suitable for a current communication condition of the UE for the UE according to a handover reason in the handover request, and notifies the UE of information regarding the determined RAT and information regarding the corresponding carrier frequency resource; and the UE performs QoS verification on the RAT and the corresponding carrier frequency resources notified by the BS, and switches to the corresponding carrier frequency with the RAT notified by the BS when the QoS on the RAT and the corresponding carrier frequency resources is superior to that of current communication. Meanwhile, the disclosure further discloses a system for handover based on a radio resource allocation database. The disclosure improves a resource usage rate and the QoS of a current communication system. The disclosure enables the UE to complete the handover quickly, such that user experience is improved.
