摘要： A method and apparatus reduces the ambiguities in the determination of cellular telephone locations in a location finding system based on the use of multipath signals. A location finding base station determines a signal signature from a subspace of an array covariance matrix. The signature is compared to a database of calibrated signal signatures and corresponding locations, and a set of likely locations whose calibrated signatures best match the measured signature is selected. A subset of most likely locations is selected from among the likely locations by comparing a function which represents how closely the measured signature matches the set of calibrated signatures with functions which represent how closely each likely signature matches the set of calibrated signatures. The locations corresponding to the best matching function are selected.

摘要： The present disclosure provides a method, an apparatus and a system for informing a serving cell handover, which relate to radio communication technology, and can greatly reduce delay of the handover of the HS-DSCH serving cell, decrease the drop call rate, and enhance user's experience. The method for informing a serving cell handover includes: a radio network controller (RNC) sets up a radio link with a candidate cell, and sets configuration for the candidate cell during the process of setting up the radio link; the RNC sends configuration information of the candidate cell to user equipment (UE); and after acquiring an optimum cell, the RNC informs, through an Iub interface signaling message, a target base station of sending a serving cell handover instruction to the UE. The serving cell handover instruction instructs the UE to hand over to the optimum cell according to the configuration information. The present disclosure is suitable for occasions where the serving cell hands over in the radio network.

摘要： A method apparatus and system for cell handover are provided. The method includes the following steps. User equipment (UE) initiates a cell handover. If the UE is not in a downlink discontinuous reception state, the cell handover is performed when the UE is not in the downlink discontinuous reception state. If the UE is in a downlink discontinuous reception state, the UE exits the downlink discontinuous reception state and performs the cell handover when the UE is not in the downlink discontinuous reception state. The embodiments of the present invention prevent the problem that the UE cannot receive a handover indication command during the cell handover in time because the UE is in the downlink discontinuous reception state, thus reducing time delay of the cell handover, avoiding longer service interruption, and reducing the call drop rate.
