Abstract

In this paper, we propose implementation of Internet protocol multimedia subsystem (IMS) for femtocell network. Femtocells designed for deployment in subscriber homes, are generating tremendous excitement among mobile operators. Femtocell promises improved indoor coverage and increased throughput for mobile data services while off-loading traffic from expensive macro radio networks onto the low cost public internet. There are some problems when femtocell supports legacy circuit switch (CS) domain user using IMS as a core network. Femtocell has a function for translation of CS number format to international format used in IMS network. The aim of this paper is to provide application plans of femtocell for IMS.
