【資料目錄和簡介】：

This document presents the possible architectures of the 3GPP System covering both UTRAN and GERAN radio access technologies. In addition, this document also includes the Evolved Packet System providing support for E-UTRAN radio access technology in addition to UTRAN and GERAN radio access technologies. As well as providing support for E-UTRAN, UTRAN and GERAN radio access technologies, the Evolved Packet System also provides support for non-3GPP access technologies making it possible for these technologies to interwork with the 3GPP specified Evolved Packet Core network. The configuration of non-3GPP access networks using EPS is not within the scope of 3GPP specification.
This document also presents the architecture for the IP Multimedia Subsystem common to 3GPP and other access systems such as Fixed Broadband and those specified by 3GPP2 and provide architecture for interworking and session continuity between IMS and Circuit Switched systems.
