3GPP standards release 8 and 9 have introduced Long Term Evolution (LTE) Radio Access Technology (RAT) to provide broadband services to end users. LTE is an all-IP packet switched technology. The evolution path towards LTE can be done in two ways. First, for GSM only operators, internetworking between GSM networks and LTE is envisioned to go through IP Multimedia Subsystem (IMS). Second, for 3G/3...
Handover is the process of maintaining session Quality of Service (QoS) while the customer is changing radio access network point of attachment. Handover due to mobility, while seamlessly maintaining service continuity and QoS is one of the 3GPP standard requirements. Handover with in 2G/3G cellular networks has been successfully and widely deployed. However, deployment of new radio technologies in...
In this paper we present the results on performance evaluation of 6-sector-site deployment and compare against 3-sector-site deployment in the downlink UTRAN LTE systems. To facilitate the performance evaluation a quasi-dynamic multicell system level simulator that follows the 3GPP UTRAN LTE specifications has been used. A significant gain in the order of 88% in site capacity is achieved by changing...
