If the second information contains state information of the feeder link of the second satellite, the third information can be sent to the terminal to indicate whether the first device supports the store-and-forward function; or if the second information contains state information of the feeder link of the second satellite, and the state information indicates that the feeder link is unavailable, and the second device does not support the store-and-forward function, and the first device also does not support the store-and-forward function, the connection and / or service of the air interface can be determined to be closed; or the target operation can also be determined according to various contents in the second information based on other any possible rules, and the specific operation can be personalized according to actual satellite network application requirements.
