The IP multimedia subsystem (IMS) functionality is designed to work on a variety of wireless access technologies and in all network coverage such as macrocell, microcell and femtocell. In this paper we have implemented an IMS registration procedure for the LTE-based femtocell networks. Additionally, we proposed the SIP based IMS framework mechanism for LTE-based femtocell implementation. Two processes...
The aim of designing the architecture for the IP multimedia subsystem is to provide fixed and mobile multimedia services independent of the access network technologies. One of these access networks is the 4th generation broadband LTE which supports femtocell deployment as to improve the indoor end-user experience. In this work we proposed an IMS module for the signalling in the LTE-based femtocell...
