EPC/IMS
From Iptechwiki
Description
3GPP by means of the system architecture evolution (SAE) technical study defines an Evolved Packet Core (EPC) as the result of the evolution of PS core network domain for GERAN and UTRAN to all IP architecture. EPC includes support for both 3GPP (LTE, WCDMA/HSPA, GSM, etc.) and non-3GPP (WiMAX, WLAN, etc.) access technologies providing seamless mobility between them. EPC has been developed with the IP multimedia subsystem (IMS) in mind. IMS represents a uniform open architecture platform for a managed IP-based infrastructure that will enable to support access to basic calling services in all-IP network and to provide an unlimited number of wireless-enhanced rich multimedia services that mix telecom and data services.
EPC/IMS research activity within the IP Technologies Area is called “IMS-capable Evolved Packet Core for enabling Next Generation Network services” and focused on following research lines:
• estimation of traffic load generated by NGN/IMS services towards PSCN/EPC from users of 3GPP and non-3GPP network,
• network dimensioning of PSCN/EPC nodes,
• CN data offloading,
• working out of ways to create and orchestrate wireless-enhanced rich IP multimedia services by means of the IMS platform over EPC for heterogeneous access networks,
• study of different IMS aspects related with an architecture to enable IMS-capable femtocell subsystem,
• deployment of IMS prototype based on open source software to evaluate the performance of IMS-related components and different IMS/NGN services and integration of the prototype with the EXTREME testbed® to validate IMS operation in close-to-real environment.
