Abstract: A method for selecting a cell in a non-terrestrial network (NTN) The method includes user equipment queries whether there is first prestored information and determines a frequency for preferential searching based on the first prestored information. The user equipment then determines values of a first decision factor, a second decision factor, a first weighting coefficient, and a second weighting coefficient in a first decision criterion. The user equipment searches for a cell according to the determined first decision criterion and selects a cell with the largest value of the first decision criterion is largest to camp.

Abstract: A satellite communication method and a network device are disclosed. A first network device learns of traffics of a plurality of satellite communications link or air interface resources allocated to a plurality of satellite base stations. The first network device sends identification information to a second network device, where the identification information indicates that a traffic of a satellite communications link reaches a specified threshold, or that an air interface resource allocated by a ground station to a satellite base station reaches a specified threshold. The second network device receives an identifier message, determines a to-be-linked satellite base station that has an idle resource, and sends, to the to-be-linked satellite base station, a second message including information about a generated beam of the to-be-linked satellite base station.

Abstract: An inter-satellite link construction method includes receiving, by a first satellite, an inter-satellite link creation message of a second satellite. The inter-satellite link creation message includes at least one of an address of the second satellite or a satellite number of the second satellite. The address of the second satellite is determined based on a projection location of the second satellite on a second ground projected track. The inter-satellite link construction method also includes, in response to the second satellite and the first satellite satisfying an inter-satellite link matching rule, creating, by the first satellite, an inter-satellite link between the first satellite and the second satellite. The inter-satellite link matching rule is determined based on at least one of the address of the second satellite or the satellite number of the second satellite.
