1. A non-terrestrial network (NTN) communication method, comprising:
determining, by a first network device, cell type information of a cell covered by a second network device; and
sending, by the first network device, a message carrying the cell type information of the cell to a third network device,
wherein the cell type information indicates whether the cell is a terrestrial network communication cell or a non-terrestrial network communication cell; and, when the cell type information indicates that the cell is a non-terrestrial network communication cell, the cell type information further indicates an orbit type of the second network device; and
wherein the cell type information further indicates whether the cell is a moving cell or a fixed cell.
 
7. A non-terrestrial network (NTN) communication apparatus, wherein the apparatus is a first network device or the apparatus is used in a first network device, and the apparatus comprises:
at least one processor; and
one or more memories including computer instructions that, when executed by the at least one processor, cause the apparatus to perform operations comprising:
determining cell type information of a cell covered by a second network device; and
sending a message carrying the cell type information of the cell to a third network device,
wherein the cell type information indicates whether the cell is a terrestrial network communication cell or a non-terrestrial network communication cell; and, when the cell type information indicates that the cell is a non-terrestrial network communication cell, the cell type information further indicates an orbit type of the second network device, and wherein the cell type information further indicates whether the cell is a moving cell or a fixed cell.
 
12. A non-terrestrial network (NTN) communication apparatus,
wherein the apparatus is a third network device or the apparatus is used in a third network device, and the apparatus comprises:
at least one processor; and
one or more memories including computer instructions that, when executed by the at least one processor, cause the apparatus to perform operations comprising:
receiving a message carrying cell type information sent by a first network device, wherein the cell type information indicates whether a cell covered by a second network device is a terrestrial network communication cell or a non-terrestrial network communication cell; and
storing the cell type information,
wherein, when the cell type information indicates that the cell is a non-terrestrial network communication cell, the cell type information further indicates an orbit type of the second network device; and
wherein the cell type information further indicates that-whether the cell is a moving cell or a fixed cell.
