Abstract
One embodiment of the present disclosure relates to a method implemented by a first gateway node for processing an emergency call from an untrusted non-3GPP access network. The method comprises: receiving an emergency call request initiated from a terminal device over an untrusted non-3GPP based access network; detecting an event of the emergency call depending upon the emergency network access identifier included in the request message; selecting for the terminal device an emergency access point name that identifies an external network providing an emergency call service; and establishing for the terminal device an emergency call session with a second gateway node interfacing with the external network which is identified by the selected emergency access point name. According to an aspect of the present disclosure, there are provided corresponding methods and devices.
