The present invention discloses an inter-RAT cell reselection method, a terminal, and a network side device. The method is: sending, by a terminal, a first request message to a first base station, where the first request message carries first cause indication information, the first cause indication information indicates that the terminal needs to perform a cell reselection process from a second base station to the first base station, the first base station is located in a first radio access technology (RAT) system, the second base station is located in a second RAT system, the terminal is in a first connected mode when connecting to the second base station, and the first RAT system does not support the first connected mode; and receiving, by the terminal, an acknowledgement returned by the first base station for the first request message, and switching the first connected mode into a second connected mode based on the acknowledgement, where the first RAT system supports the second connected mode.

When a tall vehicle stops near an access point, reception of application information from the access point may be hindered. Calculation as to whether or not a radio wave from the access point is blocked by an obstacle such as a tall vehicle is performed on the basis of obstacle information created by the access point. If the radio wave is blocked, connection to another access point around the access point from which the radio wave is blocked is searched for.

Embodiments of the present invention provide systems and methods for a Session-level SDT component in the control plane to handle setup, recovery and mobility of individual session requests in real time. The Session-level SDT component may comprise path management that performs either stateless of stateful path switching for an ongoing session, whether download or uplink, according to the stateful requirements of the session. The path management may be in conjunction with user equipment mobility management operation; it may also be in conjunction with network scalability and automation operation, such as load balancing.

A communication apparatus aims to maintain directional communication even when a surrounding environment changes. The communication apparatus has a communication unit having a plurality of antenna elements and performs wireless communication with another communication apparatus by directional communication; an image pickup unit configured to shoot a surrounding environment; and a control unit. The communication unit controls directivity of the wireless communication being by changing phases or strengths of signals from the plurality of antenna elements. Before a communication route through which the communication unit is performing the wireless communication with the another communication apparatus is blocked, a switching candidate communication route is set based on a shot image of the surrounding environment shot, whereas if the communication route with the another communication apparatus is blocked, the directivity of the wireless communication by the communication unit is controlled to switch to the switching candidate communication route.

Systems and methods for managing the link topology of a directional wireless network having mobile communications nodes. In a general aspect, the method includes the steps of receiving a plurality of resource requests from a plurality of mobile communications nodes, classifying the received plurality of resource requests as at least one class of traffic flow overlay having one or more specified constraints, determining a link topology solution based upon the at least one class of overlay and the one or more specified constraints, and publishing a topology policy based upon an optimized link topology solution to the plurality of communications nodes. The determination of the link topology solution may involve the use of a mixed integer linear programming solver, a Lagrangian relaxation solver, and/or a Lagrangian relaxation solver implementing a Lagrangian heuristic.

The technology disclosed herein relates to enhanced millimeter (mm) wave coverage based on mm wave interactions with physical objects. For example, the technology disclosed herein can receive and store physical object data for physical objects located within a coverage area provided by antenna elements, which are each within a threshold distance of each other. Further, a location of a user device within the coverage area can be identified. An algorithm (e.g., an adaptive learning algorithm) can be used to determine a mm wave transmission path based on the location of the user device and the physical object data. For example, the algorithm can account for reflections and refractions of the mm wave signal with the physical objects. One or more of the plurality of antenna elements can transmit a mm wave signal for the user device to receive based on the determined mm wave transmission path.
