Abstract
This application provides a non-terrestrial network (NTN) communication method and an apparatus. When performing a delay-sensitive communication service, UE may select a cell covered by a satellite since the UE cannot distinguish between a cell covered by a terrestrial base station and the cell covered by the satellite. A first network device determines cell type information of a cell covered by a second network device, where the cell type information indicates that the cell is a terrestrial network communication cell or a non-terrestrial network communication cell; and the first network device sends the cell type information to a third network device.
Claims19
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.
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.
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.
