Universal Mobile Telecommunications System (UMTS); LTE; Access to the 3GPP Evolved Packet Core (EPC) via non-3GPP access networks; Stage 3 (V11.4.0; 3GPP TS 24.302 version 11.4.0 Release 11)
The present document specifies the discovery and network selection procedures for access to 3GPP Evolved Packet Core (EPC) via non-3GPP access networks and includes Authentication and Access Authorization using Authentication@ Authorization and Accounting (AAA) procedures used for the interworking of the 3GPP EPC and the non-3GPP access networks. The present document also specifies the Tunnel management procedures used for establishing an end-to-end tunnel from the UE to the ePDG to the point of obtaining IP connectivity and includes the selection of the IP mobility mode. The non-3GPP access networks considered in this present document are cdma2000? HRPD and Worldwide Interoperability for Microwave Access (WiMAX)@ and any access technologies covered in 3GPP TS 23.402 [6]. These non-3GPP access networks can be trusted or untrusted access networks. The present document is applicable to the UE and the network. In this technical specification the network is the 3GPP EPC.
