  • Patent number: 11122446
    Abstract: The invention provides a method and system for managing a plurality of Wi-Fi access points using a cloud based adaptive software defined network (A-SDN). The measurement data corresponding to a plurality of network variables are collected from one or more Wi-Fi access points and one or more client devices. Once the measurement data are collected, optimal operating channels and optimal transmit power for the one or more Wi-Fi access points are derived based on one or more network variables, backhaul limits corresponding to the one or more Wi-Fi access points and a download behavior of the one or more client devices using a real-time optimization. The real-time optimization includes deriving the optimal settings through heuristic solutions of an optimization problem formulated as a Mixed Integer Nonlinear Programming (MINLP) and a machine learning based optimization.

  • Patent number: 10412646
    Abstract: A method and system for transferring user equipment (UE) in a mobile communication system are disclosed. According to the method, a source core (CN) network determines to transfer a UE that it serves and sends a transfer instruction carrying UE transfer restriction information to the UE; an access network receives a transfer request that is sent by the UE according to the restriction information carried in the transfer instruction; the access network selects a target CN entity that is different from the source CN entity for the UE; and the UE is transferred to the target CN entity. The method and system provided by the disclosure are applicable to user transferring between CN entities in any communication network. The transferring is initiated by a network side entity, and a more preferable CN entity is selected for the UE to provide a better service.

  • Patent number: 10397964
    Abstract: In a wireless communication system, a terminal apparatus is capable of reporting, to a base station apparatus, information indicating a mobility state of the terminal apparatus. In a case where the terminal apparatus reports information (history information) to the base station apparatus as mobility state indicating information, the terminal apparatus notifies the base station apparatus of a radio resource control connection setup complete message containing information indicating the presence of the history information that is notified as the mobility state indicating information. The history information contains an identifier of a cell that the terminal apparatus visited and the duration of stay in the cell. The base station apparatus notifies the terminal apparatus of information as to whether to report the mobility state indicating information.

  • Patent number: 10349380
    Abstract: A base station transmits to a second base station, a first message comprising a first RAN area identifier of the first base station. The first base station receives from the second base station, a second message comprising a second RAN area identifier of the second base station. The first base station transmits to a wireless device, RRC message(s). The RRC message(s) comprises the first RAN area identifier. The RRC message(s) indicates a state transition of the wireless device to an RRC inactive state. The first base station receives packet(s) for the wireless device. The first base station transmits to the second base station, and in response to receiving the packet(s), a RAN paging message when the first RAN area identifier is identical to the second RAN area identifier. The RAN paging message comprises an identifier of the wireless device and the first RAN area identifier.
