Since the advancement of current cellular systems and technology is augmented towards 4G(4th Generation) and beyond, the need for efficiency in terms of the Quality of Service(QoS) and reducing the signaling overhead between the mobile node and the various other equipment providing services within the core network becomes critical. Selection of application as per the user preference has much importance in the 4G networks. In 4G networks it is necessary to integrate WLAN (IEEE 802.11) systems with currently existing UMTS, GPRS systems which provide for wider mobility requirements, if the user requires obtaining a substantial amount of bandwidth within a hot-spot province.
