Abstract: Methods and systems for predicting a cell capacity associated with a cell of an electrochemical cell system are provided. In one exemplary embodiment, the method determines a first predicate cell capacity of the cell of the electrochemical cell system. The method further includes measuring a voltage of the cell to obtain a measured voltage. The method further includes determining a corrected predicted cell capacity of the cell based on the first predicted cell capacity, the measured voltage, and a gain factor.

Abstract: The present invention relates to an implementation of a battery State of Charge (SOC) estimator for any battery type. It addresses the problems associated with the existing implementations such as high error uncertainty, limited application (i.e. only one battery type) and susceptibility to temperature changes. Embodiments of the present invention use Kalman filter or Extended Kalman filter for a battery model that has SOC as an internal system state. Having an SOC internal state allows the invention to provide an uncertainty associated with its SOC estimation. One embodiment does not take battery temperature as a parameter in its SOC estimation. Another embodiment uses battery temperature as a parameter to adjust its SOC estimation to keep the accuracy of the SOC estimation from being affected by changing temperature. One embodiment allows different modeling parameters during battery operation to accommodate highly dynamic batteries used in Hybrid Electric Vehicles and Electric Vehicles.

Abstract: The call set-up technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen. Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference, as measured by the base station. The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.

Abstract: The call hand-over technique of this invention is characterized by the use of channel information from both the target base station and subscriber terminal in determining which radio traffic channel will be used to hand over a call in progress from a serving base station to a target base station. Calls are handed over to the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured by the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference, as measured by the target base station. The hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both the target base station and subscriber terminal.

Abstract: The intra-cell call hand-over technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining a standby radio traffic channel upon which to hand over a call. Communication between the base station and subscriber terminal is carried out on an inband or associated signalling channel for the selection of the standby traffic channel. The standby radio channel is the channel, which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference as measured by the base station. The call hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.

Abstract: An improved radio link architecture for digital wireless communication systems which is characterized by the use of information and signalling channels on a number of RF carriers, thereby providing common signalling channels for call set-up and control functions. A first group of RF carriers are allocated as traffic channels between base stations and subscriber terminals. Each RF carrier in the first group comprises at least one traffic channel. A second group of RF carriers is allocated for providing common signalling channels between the base stations and the subscriber terminals. Each RF carrier having common signalling channels operates in time division multiple access mode, and each common signalling channel being time division duplexed.
