Abstract

The invention discloses a method, a system and a device for predicting a node to move out of a subnet based on position information. The method comprises the steps of: acquiring a speed vA, a course CA, longitudes and latitudes phi A and theta A, a speed vB, a course CB, longitudes and latitudes phi B and theta B, and a maximum communication range R between a node A and a node B; calculating an angular distance delta AB formed by the two nodes by taking the center of the earth as a vertex; calculating a linear distance S between the two nodes according to the angular distance delta AB and the flight height HA of the node A or the angular distance delta AB and the flight height HB of the node B; calculating an azimuth angle gamma of the node B relative to the node A; calculating an included angle alpha between the course of the node B and the course of the node A; calculating an included angle beta between a connecting line between the two nodes and the course of the node A; and calculating link duration between the node A and the node B according to the vA, the vB, the S, the R, the alpha and the beta, and predicting the time when the node moves out of the subnet. According to the method, prediction is accurately made by predicting the node to move out of the subnet, and the network performance is improved.

Description

Technical field [0001] The present invention relates to the field of layered self-organizing networks, and more particularly to a method, system, and apparatus for moving out the subnet based on a location information prediction node. Background technique [0002] In a hierarchical self-organizing network, the node has severe changes in the network topology when the node is free to move, and the node may move out of the subnet and move into the new subnet. In order to adapt to this node to move between the child network The routing failure problem and the mobile node cause communication interruption during the switching process, affecting network performance, requires the duration of the link, and the predictive node moves out of this subnet. Inventive content [0003] It is an object of the present invention to provide a method, system, and apparatus for moving out the subnet based on a location information prediction node, intended to resolve the predictive node to move out th...
