Problems solved by technology

In the related art, according to the communication quality requirements of different mobile terminals, a method for the terminal to simultaneously establish a communication link through the original terrestrial mobile network access network (terrestrial access network) and satellite access network is proposed. However, in the actual implementation process In this dual-link solution, there are still many problems, one of which is: the mobile terminal needs to switch the access and mobility management network elements of the core network. In this case, how should the two links For switching, how to determine the switching sequence of links... For these problems, related technologies still lack a more feasible solution

Abstract

The invention discloses a ground and satellite fusion link switching method and system, and the method comprises the steps: enabling a terminal to access a link of a core network through a satellite access network, and enabling the terminal to access a link of the core network through a ground access network; according to the embodiment of the invention, a scheme that double-link switching is initiated by core network access at one side of a ground access network and switching of a mobility management network element is provided, and a link at one side of a satellite access network initiates switching according to link switching at one side of the ground access network, so the situation that connection between a terminal and the ground is unavailable due to satellite movement is prevented; the success rate of double-link switching is improved, a feasible scheme is provided for the double-link switching problem, and the method plays a positive role in development of a mobile network in which the ground and a satellite are fused. The embodiment of the invention can be widely applied to a ground and satellite fused mobile network system.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a ground-satellite fusion link switching method and system. Background technique [0002] With the continuous development of communication technology and the advent of the 5G era, the network transmission quality of terrestrial mobile communication is getting higher and higher. However, in some remote mountainous areas and other places, terrestrial mobile communication cannot achieve full coverage. The signal coverage of satellite communication is wider, and it can provide network signals for many areas that cannot be covered by terrestrial mobile signals. With the further development of mobile communications, it is foreseeable that the future trend will be the integration of terrestrial mobile networks and satellite mobile networks, and each will play to its strengths. In the related art, according to the communication quality requirements of different mobile termina...
