摘要： A bandwidth sharing method and device based on SDN control of terminal cell are disclosed. The bandwidth sharing method includes: determining, by a SDN controller, whether a trigger request for bandwidth sharing is received; upon receipt of the trigger request, selecting at least one second terminal cell for providing bandwidth sharing to the first terminal cell; controlling the first terminal cell and the at least one second terminal cell to jointly process the target service. The trigger request indicates a need of bandwidth sharing of a first terminal cell from other terminal cells when processing a target service on a backhaul link, and a bandwidth requirement of the target service equals to or exceeds a first predetermined threshold. The SDN controlled bandwidth-sharing scheme may ensure the application of a wireless backhaul sharing mechanism between T-SCs, thereby achieving flexible configuration of bandwidth resources on the backhaul link.

摘要： The present invention discloses a connection management method in device-to-device (D2D) relay communication, a terminal and a base station. The connection management method in D2D relay communication includes: determining whether a relay terminal for performing the D2D relay communication is selected when an Radio Resource Control (RRC) connection between a remote terminal in a network coverage and a base station is not released; when the relay terminal is determined to be selected, determining whether the RRC connection with the base station can be released according to a resource configuration mode used by the remote terminal when performing a D2D communication. By utilizing the connection management method, problems of state transition and connection management of the terminal in the D2D relay communication can be solved.

摘要： A method for reporting terminal location in a vehicle communication includes: detecting a location relationship with other terminals by a terminal, to determine a target terminal related to a location of the terminal. Location correlation information between the terminal and the target terminal to a base station or network side equipment is reported, to enable the base station or the network side equipment to select a terminal that needs to report a location from the terminal and the target terminal according to the location correlation information. By utilizing embodiments of the present disclosure, when a terminal reports a location, it is unnecessary for all terminals to report locations, unnecessary location reporting messages are reduced, loads on a base station or a network side caused by the terminals reports the locations are decreased, and also uplink resources of the base station or the network side are saved.

摘要： A channel detection method and system of an LTE system in an unlicensed frequency range, a device having base station functions, and a terminal are provided. The method includes: dividing an unlicensed frequency range into several frequency bands; setting a determination threshold value corresponding to each frequency band for detecting busy/idle states of channels in each frequency band; setting channel monitoring subframes for detecting the downlink channel state and/or the uplink channel state in each frequency band in the frame structure of the LTE system; detecting the busy/idle states of the downlink channel and/or the uplink channel in each frequency band according to the determination threshold value. The present invention increases a spectrum utilization rate of the unlicensed frequency range, and prevents an LTE system working in the unlicensed frequency range from causing large interference to other systems while ensuring the LTE system works in the unlicensed frequency range normally.

摘要： An embodiment of the disclosure provides a resource partition aggregating method and a device, the method includes acquiring a resource utilization ratio of each resource partition in a first signal unit. When there is a resource utilization ratio of each resource partition of at least two adjacent resource partitions in the first signal unit is less than a first preset threshold, whether a zone index used after aggregating the at least two adjacent resource partitions causes a communication interference with zone indexes used by resource partitions in an adjacent second signal unit is determined. If no communication interference is caused, determining area distribution parameters of the aggregated at least two adjacent resource partitions. A broadcast message carrying the area distribution parameters to a vehicle terminal is sent. By using the embodiment of the present disclosure, a resource utilization ratio can be improved.

摘要： An RRM measuring method of an LTE system in an unlicensed frequency band, a system, a terminal and a base station are provided. The method includes: receiving a downlink signal sent by each base station in at least one base station to determine a busy/idle status of an uplink channel and/or a downlink channel of each base station; calculating a value of RSRQ of each base station, when the uplink channel and/or the downlink channel of each base station is in a busy state or in an idle state; reporting the values of RSRQ to a service base station. The present disclosure measures the values of RSRQ according to the channel statuses of the base station, thus the serving base station determines the service performance of a neighboring base station to select a more appropriate auxiliary cell base station or a target base station when switching.
