Abstract

The invention provides a non-ground network switching method and system without positioning capability of a terminal, and the method comprises the steps that M1, through information of a source air communication node, the source air communication node periodically calculates the service duration and service interruption time of a service provided by the source air communication node for the terminal in a service geographic region; m2, the source air communication node periodically sends a space information request to candidate air communication nodes in a broadcasting mode, one or more candidate air communication nodes feed back space information to the source air communication node, and the source air communication node selects a target air communication node for a ground terminal in theservice area according to the fed back space information; and m3, the target air communication node is switched to after the service of the source air communication node is interrupted according to aswitching command sent by the source air communication node. According to the invention, the switching problem of a large number of terminals without positioning capability in a 5G and B5G mobile communication system with integration of a ground network and a non-ground network is solved.

Description

technical field [0001] The present invention relates to the field of non-terrestrial networks (NTN, Non-terrestrial networks), in particular to a non-terrestrial network switching method and system in which a terminal has no positioning capability. Background technique [0002] With the increasing maturity of 5G (fifth generation mobile communication system) technology, the integration of non-terrestrial communication platforms represented by satellites and terrestrial communication networks has attracted more and more attention, including 3GPP (Third Generation Mobile Communication Partnership Project ), ITU (International Telecommunication Union) and other international standardization organizations have set up a special working group to study the standardization of satellite-ground integration. Enterprises and research organizations in the industry have also invested in the research work of satellite-ground integration. [0003] Taking 3GPP (Third Generation Partnership P...
