[0067] S220, establishing a communication connection based on the satellite information.

[0068] The communication establishment method provided by the embodiment of the present disclosure sends a subscription request to the AMF network element when it is determined that the terminal needs to adopt satellite services, so that the AMF network element determines the satellite information corresponding to the terminal based on the subscription request, and sends the satellite information to the SMF network element. In this way, the SMF network element can subscribe the satellite information corresponding to the terminal to the AMF network element for the terminal that may adopt satellite services, thereby avoiding the AMF network element from sending a large amount of invalid information to the SMF network element.
