Problems solved by technology

[0006] The inventor found in the process of studying the prior art that the existing handover method considers the situation of linear coverage when determining the timing of the pre-handover, and ideally regards the position of the next handover as a point, which affects the pre-handover The precision of the timing leads to a high failure rate of the mobile node during the handover

Embodiment Construction

[0046] The invention provides a switching control method, a mobile node and a base station controller. In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] see figure 1 , figure 1 It is a flow chart of the first embodiment of the handover control method provided by the embodiment of the present invention. In the embodiment of the present invention, the mobile node can be installed on a high-speed train or a car, and the mobile node can be a mobile router or a relay station. The terminal equipment on the high-speed train or car is connected to the mobile network through the mobile node. The process of performing handover control in the process may specifically include:

[0048] Step A1. Obtain the current first location information and moving direction of the mobile node.

[0049] Specifically, the mobile node...

Abstract

The embodiment of the invention discloses a switching control method, a mobile node and a base station controller. In the switching control method, the mobile node computes the preswitching time and triggers the preswitching operation according to the start point of a switching section. In the prior art, during computing the preswitching time, the switching section is used as a point. Compared with the prior art, the invention has the advantages that the preswitching time computed in the embodiment of the invention is more accurate; and especially under the condition that the switching position is advanced relative to the fixed switching point, the probability that the target cell is identical to the preswitched cell or one of the preswitched cells is increased, thereby increasing the switching success rate of the mobile node and enhancing the communication quality.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a handover control method, a mobile node and a base station controller. Background technique [0002] In a wireless communication system, as the user equipment (UE, User Equipment) moves, the signal quality of the current cell of the user equipment deteriorates and cannot maintain the conditions required for communication, and the network side usually switches the user equipment to a cell with better signal quality. Adjacent cells to ensure the quality of service for users. In traditional cell handover, the network side obtains the signal strength of the current cell and neighboring cells according to the handover measurement report of the terminal, triggers the handover and selects the target cell during handover based on a certain handover decision algorithm. [0003] Due to the fast movement of large vehicles, such as high-speed trains, for the user equipment in ...
