The present disclosure relates to a mobile switching node and a mobility management node to page a terminal device. The present disclosure may provide a method for a mobile switching node to page a terminal device. The method includes: storing (S201) an indication of whether a terminal device supports a circuit switching call function; receiving (S202) a request to implement the circuit switching call function, in regard to a subscriber number corresponding to the terminal device; and sending (S203), to a mobility management node, a circuit switching paging request for the terminal device, in response to that the indication shows the terminal device supports the circuit switching call function.
