    Integrating femtocells with internet protocol multimedia subsystem
    (kca university, 2017) Agong, Raphael Wambi
    The functionality of IMS was to work with wireless access technologies and other network coverage like macro cell, microcells and Femtocells. The trend of next generation networks’ evolution is towards providing multiple and multimedia services to users through ever present networks. The aim of IMS is to integrate mobile communication networks and computer networks. The internet protocol subsystem (IMS) is a framework that was specified for the 3G mobile network to provide internet protocol telecommunication services. It supports multiple access types like GSM WCDMA, CDMA2000 or Wireless Fidelity (IEEE802.11). A Femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or not available. The Key functions of IP multimedia subsystem (IMS) are to introduce enhanced features like signal initiation protocol [SIP] (a protocol that has been devised for establishing, managing and terminating session on IP networks) in the fixed and AD HOC network infrastructures. The poor lose of signals in a an enclosed building forces communication to drop. Poor signals may be caused by poor building materials. There is no study that have been performed to addresse this problem adequatly. This study is to solve signal drops due to poor building material by integrating Femtocell with IMS.Use of Femtocells will greatly increase network capacity, coverage area, support high speed data rate and utilization of power. The focus of the study is to improve wireless signals indoors by using a Femtocell integrated with IMS. This will improve services, network capacity among other things for users and operators. Integrating a femtocell with IMS architecture will maintain the signal levels to a point that communication will not be dropped. Femtocell will improve signals by about 10% both TX and RX in an average distance of 10M between the ME and Femtocell.
