摘要： A method implemented in a UE. NAS signaling is initiated or performed for an emergency call in order to establish a connection between the UE and one of a plurality of core networks (CNs). In a non-limiting example, the NAS signaling is initiated or performed after the ending of a prior established connection or emergency call. A determination is made whether the UE is already attached for emergency bearer services. Responsive to the UE being already attached for emergency bearer services, a NAS layer of a protocol stack of the UE causes transmission of a UE identification (ID) when requesting a radio resource control (RRC) connection for further NAS signaling. The UE ID includes data which can be used to determine to which CN of the plurality of CNs the connection should be directed.
