context: using the IP-CAN bearer for SIP signalling. [TS 24.302 Rel-14, clause 7.2.1A]: The UE performs ePDG selection for emergency bearer services based on the ePDG configuration information provided by the home operator in the UE via H-ANDSF or via USIM, or via implementation specific means: The ePDG configuration information used for selecting the ePDG for emergency bearer services includes: - when available in ANDSF MO, Emergency_ePDG_Identifier and ePDG selection information are provisioned in ePDG node under Home Network Preference as specified in 3GPP TS 24.312 [13]; and - when available in the USIM, the Emergency ePDG Identifier and ePDG selection information are provisioned in EFePDGIdEm and EFePDGSelection files as specified in 3GPP TS 31.102 [45]. NOTE: Implementation specific means apply only if the configurations via H-ANDSF and USIM are not present. When performing ePDG selection for establishing emergency bearer services, the UE shall proceed by following the general ePDG
description: The Evolved Packet Data Gateway (ePDG) provides connectivity between user equipment (UE) and the packet data network (PDN) in the evolved packet system (EPS). It acts as an entry point for UEs to access the PDN, enabling secure and authenticated communication.
explanation: The text describes ePDG's role in managing UE connections to the PDN, handling SIP signaling, emergency bearer services, and its selection based on configuration. These functions are characteristic of a Network Function responsible for network traffic routing and control.
