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.

Abstract: A mobility management node and a method in a mobility management node for reducing signalling caused by changes of location of a radio terminal, which mobility management node is configured to be operatively comprised by a wireless communication system and to operatively manage the mobility of the radio terminal and to operatively communicate with a gateway node acting as an interface between the system and an external network. The method comprises obtaining initial position information; obtaining boundary information indicating a boundary area wherein at least one of a policy or a charging rule is to be applied for the radio terminal; obtaining current position information; determining whether the radio terminal is inside or outside the boundary area; providing mobility information when the radio terminal is outside the boundary area and not providing mobility information to the gateway node when the radio terminal is inside the boundary area.

Abstract: A method for selection of a core network. The method which can be performed by a first network node comprises receiving a message for a terminal device from a second network node. The message can enable the first network node to determine a category of the terminal device. The method further comprises selecting a core network for the terminal device based at least in part on the category of the terminal device. The terminal device can be served by a dedicated core network selected for the terminal device adaptively, so that network configuration and resource efficiency can be improved.
