Abstract

Methods and apparatuses are disclosed for implementing mobile terminating call. According to an embodiment, a subscriber management node obtains, from a mobility management node, an indication that indicates whether a packet switching (PS) connection is currently active for a terminal device. The subscriber management node receives, from a server, a first query about whether a PS access domain is to be used for a terminating call to the terminal device. The subscriber management node sends a response to the server based on the obtained indication.
