  • Patent number: 12217288
    Abstract: The disclosed systems can regulate access to an online mode for a dynamic transportation matching system. For example, based on a provider efficiency parameter associated with the dynamic transportation matching system, the disclosed systems can prevent a transportation provider device from switching to the online mode within a geographic area. In addition, the disclosed systems can detect a pattern of behavior and, based on a comparison between the pattern of behavior and a behavioral threshold, cause a transportation provider device to switch from the online mode to an offline mode. Further, the disclosed systems can provide a map interface that indicates where a transportation provider device can switch from the offline mode to the online mode. Additionally, the disclosed systems can determine priorities associated with transportation provider devices and, based on the prioritization, selectively allow the transportation provider devices to switch from the offline mode to the online mode.

  • Publication number: 20150257092
    Abstract: A method and a base station for a cell selection are provided. The method comprises obtaining an uplink traffic status of a user equipment. The method also comprises determining, based upon the plink traffic status, a bias value for a measured quality indicator of a down link received signal with respect to the user equipment. In addition, the method comprises performing the cell selection based upon the bias value and the measured quality indicator. With the present invention, a proper cell could be selected and thus both peak DL and UL throughput can be improved in the heterogeneous network.
