Switching method, switching device and communication equipment

Abstract

The invention provides a switching method, a switching device and communication equipment, and belongs to the field of wireless communication. The switching method is applied to an aircraft and comprises the following steps: reporting flight information of a service base station to the service base station; receiving reserved wireless resource information sent by the service base station, whereinthe reserved wireless resource information is generated according to the flight information; and initiating random access and / or data transmission to a candidate cell base station by using the wireless resources indicated by the reserved wireless resource information. Through the technical scheme of the invention, the switching success rate of the aircraft can be improved, the switching performance and the user experience are improved, and meanwhile, the waste of reserved resources is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a switching method, switching device and communication equipment. Background technique [0002] Due to flight safety considerations and the limitation of communication network coverage, civil aviation aircraft has always been a communication blind spot, and the potential of the civil aviation communication market has yet to be discovered. At present, there are two main implementation methods for the communication link from civil aviation aircraft to the Internet: communication satellite forwarding and ground base station air coverage (ATG). Compared with satellite communications, ATG has natural bandwidth and cost advantages, and is more suitable for domestic land flights. However, the coverage of ATG is smaller than that of satellites, and it still needs to switch between cells when serving civil aviation aircraft. [0003] A current handover method is p...

AI Technical Summary

Problems solved by technology

Due to the fast flight speed of civil aviation aircraft, they may penetrate into neighboring cells during the handover waiting time, so the handover command sent by the original serving cell cannot be correctly received due to excessive interference from the neighboring cells, resulting in handover failure, which seriously affects handover performance and user experience.

For the pre-handover method, since candidate cells need to reserve resources, if the selection of candidate cells is unreasonable, it may cause waste of channel resources and large signaling overhead
