1. A method for processing cell handover, applicable to user equipment side and comprising:
obtaining a current movement trajectory;
matching the current movement trajectory with historical movement trajectories to obtain matching degrees;
determining a target cell according to the historical movement trajectory of the matching degree greater than a preset matching threshold, and correspondences between historical movement trajectories and cells; and
sending a handover request to a source base station, the handover request comprising a target cell identifier of the determined target cell,
wherein the method further comprises:
obtaining a current movement speed,
wherein the determining the target cell according to the historical movement trajectory of the matching degree greater than the preset matching threshold, and correspondences between historical movement trajectories and cells comprises:
determining the target cell according to the historical movement trajectory of the matching degree greater than the preset matching threshold, the current movement speed, and correspondences among historical movement trajectories, movement speeds and cells,
wherein in response to that the movement speed is in a first speed range, a microcell covering the movement trajectory is determined as the target cell, in response to that the movement speed is in a second speed range, a cell covering the movement trajectory is determined as the target cell; and in response to that the movement speed is in a third speed range, a macro cell covering the movement trajectory is determined as the target cell.
