摘要： 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.

摘要： The disclosure discloses a handover method based on a cognitive technology. At least two working areas such as a Primary Working Area (PWA) and a Secondary Working Area (SWA), a RRM and a HOC are configured both in User Equipment (UE) and in a Base Station (BS); after receiving a handover request, according to the current radio environments, the PWA of the BS makes a handover negotiation with the neighboring BSs or with the neighboring BSs and the UE requesting handover, determines the communication parameters satisfying the handover request, and sends the determined communication parameters to the SWA of the BS and the SWA of the UE; the SWA of the BS and the SWA of the UE configure said communication parameters and notify the RRM of the BS after the configuration is finished; the RRM of the BS instructs the HOC of the BS and the HOC of the UE to activate the respective SWAs, and to perform the handover according to the communication parameters configured by the SWA. The disclosure also discloses a handover system based on the cognitive technology. The disclosure improves the resource utilization ratio and the quality of service in the current communication system.

摘要： The present invention discloses a method for adaptively adjusting uplink and downlink bandwidth, which includes: a base station counting a usage status of the uplink and downlink bandwidth in a preset time, and obtaining a bandwidth amount ” BW DL required to be coordinated of downlink bandwidth and a bandwidth amount ” BW UL required to be coordinated of uplink bandwidth; the base station determining a direction, amount and location of the required change of the uplink and downlink bandwidth according to the obtained ” BW DL and ” BW UL ; the base station carrying the determined direction, amount and location of the required change of the uplink and downlink bandwidth through residual ten bits in a logical channel message corresponding to a Physical Broadcast Channel (PBCH) and informing a terminal of the direction, amount and location. The present invention also discloses a device for adaptively adjusting the uplink and downlink bandwidth. With the present invention, utilization efficiency of frequency spectrum in a Long Term Evolution Frequency Division Duplex (LTE FDD) system is improved.

摘要： The present invention discloses a method for scheduling users in coordinated scheduling, which is applied in a long term evaluation-advanced system, a coordinated cell determines and stores user pairing information in initial scheduling, and the coordinated cell uses the user pairing information that has been stored to determine a scheduled user in subsequent iterative scheduling. The present invention also discloses a corresponding base station. With the scheduling schemes in the present invention, in intra-cell scheduling, user pairing information is stored in an initial scheduling process and is used in subsequent iterative scheduling without performing multiple user pairing search in the iterative scheduling, which reduces the computation amount in the iterative scheduling and system resources occupied by the iterative scheduling and accelerates the system processing time in a premise of not reducing the system performance, thereby making the performance in the whole domain trend to the optimal.
