Currently, the related art generally uses the architecture and principles of a terrestrial cellular network when facing an access scenario between a terrestrial terminal and a satellite-borne device, i.e., each satellite-borne device is allocated and establishes a connection with the terrestrial terminal using fixed and unique access information (e.g., frequency band, physical cell identifier, etc.). However, the on-board device is in a high speed motion and the area of the ground that it covers changes rapidly. When a ground terminal is served by one on-board device, the ground terminal must actively sense and switch to another on-board device using disparate access information as the on-board device flies away. This procedure results in frequent, complex handover operations, which makes the connection between the ground terminal and the on-board equipment less stable.
