Abstract: Embodiments of the application relate to the technical field of Optical Coherence Tomography (OCT) devices, and disclose a detection method and system directly applying noninvasive OCT to an endometrium, and a detection device. The method includes: inserting an OCT probe into a uterine cavity through a cervical orifice until reaching a fundus of a uterus; pulling back the OCT probe, and starting an image acquisition apparatus at the same time to obtain a plurality of OCT images; and dividing the plurality of OCT images into four areas, namely a uterine fundus area, a uterine upper section area, a uterine lower section area, and a cervical area, each area having one or more OCT images, and analyzing the OCT image of each area. By implementing the embodiments of the application, each area may be analyzed according to the OCT image, a human body cannot be injured, and the detection is accurate.

Abstract: The present invention provides a method for User Equipment (UE) handover between home Node Bs, comprising steps of: sending, by a source home Node B that stores the ID of the connected gateway, a message to the gateway, the message including the gateway ID and a destination home Node B ID; sending by the gateway a message to the destination home Node B identified by the destination home Node B ID to establish a radio bear of the destination home Node B for the UE; sending by the destination home Node B the radio bearer allocated to the UE to the gateway; sending by the gateway the radio bearer to the source home Node B; sending by the source home Node B the radio bearer to the UE; and completing by the UE a handover to the destination home Node B. With the present invention, successful handover between home Node Bs under the same access control can be guaranteed in the case of the same gateway.
