    摘要: A method of spectrum access for wireless communications by a secondary unlicensed unit in a CRN environment comprising one or more secondary unlicensed mobile units and one or more primary licensed units includes receiving information indicative of a location and movement of one or more secondary unlicensed units and a channel usage pattern and spatial distribution of one or more primary licensed units is accessed and a guard distance to shield the one or more primary licensed units from interference is calculated. The channel availability to the one or more secondary unlicensed units is then calculated according to a two-state Markov model including the guard distance as a constraint and based on the information indicative of the location and movement of the one or more secondary unlicensed units and the channel usage pattern and spatial distribution of the one or more primary licensed units.

    摘要: A method for navigation based on a cellid-aided positioning system includes: determining, at a cellid-aided positioning system-compatible device, that a user has moved through a sequence of cellids, wherein moving through a sequence of cellids comprises moving from a first region corresponding to a first cellid to a second region corresponding to a second cellid; accessing previously stored route information corresponding to the sequence of cellids, wherein the previously stored route information includes previously recorded sequences of cellids and global positioning system (GPS) information; estimating a current position of the user based on the previously stored route information; and displaying the current position of the user.

    摘要: A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the one or more of the objects. The location and image are transferred from the mobile communications device to a remote server via a wireless network, such that the one or more of the objects are identified at the server based on the image, and the location and identity of the one or more objects are stored on a database associated with the server.

    摘要: A method and apparatus for communicating over a network is provided. The method includes selecting between location-sensing methods for an LBA, such as between GPS and network triangulation. For each location-sensing method, a dynamic determination is made as to whether the accuracy of the location-sensing method, in the current environment, meets the application requirements. If two or more location-sensing methods meet the application requirements, then, location-sensing method selected is the location-sensing method that, from among the location-sensing methods that meet the application requirement, consumes the least power. Otherwise, the location-sensing method that is most accurate for the current environment is selected.
